Goal of Taxation

Sunday, July 20th, 2008

“Isn’t it lawful for me to do what I want to with what I own?” — Matt 20:1-16

A reliable distinction between Conservative and Liberals is the way they view the purposes of taxation. While it is clear that Liberals are more expansive in their view of the ways that taxes should be used for public welfare programs, Liberals also view taxes as a redistributionist tool even if its use for this purpose reduces the level of taxes available.

H. L. Menchan  once defined Puritanism as “The haunting fear that someone, somewhere, may be happy.” By analogy, please permit the observation that some Liberals scowl fretfully at the world with the apprehension that someone, somewhere, may have accumulated what Liberals judge a disproportionate amount of money.

With such an attitude, one purpose of taxation becomes punitive. It is just unfair that some people have very much more money than others. By definition, this money could not have been accumulated entirely fairly. Even people who make money in direct proportion to a conspicuous talent, like a professional athlete or an entertainer are viewed with suspicion. The fact that some of these people become extraordinarily wealthy is not evidence of extraordinary talent, but a  economic system that unfairly rewards such talent.

All would agree that taxes are needed and in general it is better demand more taxes from those with more resources. Bank robber Willie Sutton when asked why he robbed banks, is reputed to have replied “because that’s where the money is.” Similarly, government taxes the more affluent because that is where the money is. Less cynically, the affluent can be said to have benefited more from the social arrangements under which they have prospered. Hence, they have a greater obligation for its maintenance.

However, the perpetual desire to punish the affluent can sometimes create a system where ironically the affluent less pay a smaller fraction of federal taxes, despite more progressive rates. In a recent article, Stephen Moore of the Wall Street Journal cites a study by Columbia University economist Glenn Hubbard. In President Carter’s administration, the highest marginal tax rate was 70% (twice the current 35%). However, the top 1% paid only 16.7% of all federal income taxes. At the current 35% highest marginal rate, the top 1% actually pay more than twice the fraction of total federal income taxes (39%) than they did in the 1970’s. Hence, the federal income tax system became more progressive with lower marginal rates.

How can this be? The answer is simple. Capital and the wealthy who own capital have many options available to them. They can decide not to take the risks necessary to earn some additional income because the rewards are too small. They can shield themselves from taxes by finding tax loopholes, like the simple tax-free municipal bonds. They can move themselves and money overseas. Indeed, it is now far easier for capital to migrate to those regions of the world where wealth accumulation is treated more favorably than it was in the 197os.

Conservatives and Liberals rightly view taxation as a necessary expense for the functioning of government, though clearly Conservatives and Liberals differ on the proper role of government. However, it is simply wrong-headed and counterproductive for Liberals to seek to increase tax rates beyond the point where revenues go down and the federal tax system becomes less progressive to satisfy their congenital anger at the affluent.

Cars and Freedom

Sunday, June 22nd, 2008

A important notion inherent in the Conservative political perspective, often incomprehensible to Liberals, is the intimate link between money and freedom. Money, as a broad measure of economic wherewithal, provides choices. With money a person can decide where to live, what to wear and eat, where to travel to, what recreational and educational activities to engage in, and even what opportunities to provide children. The more money the broader the scope of choices in our lives. Money is so important that most of us willing trade the precious commodity of time for money in our jobs.

Personal transportation is also a measure of freedom. Sure there are some people who take special pride and interest an automobiles or manage to travel from place to place via public transportation. However, for the most part, a car allows ordinary people to control their lives like few other possessions. Cars permit us broad discretion in where to live. We are not limited to high-traffic corridors that may be serviced by mass transportation. Cars have made possible for many the achievement of the American dream of a house and yard.

Cars allow us to plan our day more independently of the schedules of others. We can on a given day, deviate from a work-route to pick up a child from baseball practice or purchase groceries.

Cars also provide a sense of possibility. One can spontaneously choose to simply jump into the car and visit grandma in the next state. One can tour and view the country more intimately from a car. The freedom of the open road underpins much of our culture and literature from the TV show Route 66, the movie The Open Road, and the book Blue Highways.

No one wonder Americans are in love with their cars. No wonder car use has increased in European countries, even those with significant mass transportation alternatives. No wonder that as both China and India have become more affluent, the population has raced to own and drive cars.

The recent tremendous increase in gas prices has robbed Americans both of a measure of both economic and transportation freedom. People feel pressure but their scope of choice as been reduced and Americans are apprehensive that it might be reduced further.

The salient political point to understand is that Americans will embrace solutions that allows them to maintain their transportation freedom. There are some on the Left who are smugly happy with high prices because they feel Republicans will be blamed and because they believe it will push people away from cars. Americans will resent this loss of freedom, even if the Left believes it is for their own good of people

There are many possible ways to alleviate the current problem including: the movement to higher mileage gs automobiles, substitution of hybrid and electric vehicles for solely gas powered cars, improving the road infrastructure to reduce eneregy-wasting bottlenecks, and increasing oil production. All will likely play an important and necessary role. However, the option to use high prices to ween people from their cars will not be politically sustainable over the long term. If the Left attacks personal freedom, they will ultimately pay a price. For example, banning offshore oil drilling can be popular when oil is $22 a barrel, less so at $130 a barrel oil.


Energy Schizophrenia

Sunday, June 8th, 2008

One problem with trying to engage Democrats on energy issues is that they are irremediably schizophrenic. In 2006, when gas prices were substantially lower than they are now, Democrats ran on a platform of reducing the price of gas. On April 19, 2006 the then minority leader Democrat Nancy Pelosi said, “Democrats have a plan to lower gas prices…join Democrats who are working to lower gas prices now.”

Whatever approach they have implemented certainly has not been successful in reducing gas prices. Indeed, aided and abetted by Republicans, the government’s mandates for use of ethanol have managed to be a failure in lowering gas prices but wildly successful in increasing the income for corporate farmers and food prices.

Regardless of the success or failure of the Democratic plan for reducing gas prices and for whatever reasons, it was clear in 2006 that lower gas prices was a prominent Democratic goal. On the other hand, the presumptive Democratic nominee Barack Obama now seems somewhat sympathetic to high gas prices, suggesting that it will push Americans toward the use of hybrids.

But how does reducing gas prices square with other goals of the Left: decreasing in carbon dioxide emissions, increasing the use of public transportation, and reversing suburban sprawl?  Accomplishing these goals will require pain and increased gas prices are the quickest and most direct way of applying the necessary discipline. If by some miracle, all the cars in the country got twice the mileage, the pain of oil prices would be reduced by a factor of two and Americans would likely drive more than they do now. However, the goals of greater use of public transportation or less suburban sprawl will be thwarted.

Thus lies the current contradiction of Democratic energy policies. They are anti-oil, but wish to make gas cheaper. They rail against the middle-class suburban sprawl, but object to the pain in gas prices that mitigates sprawl. Like a dog trapped in a yard, the are really only for action, action, action, direction is unimportant.


How Long Will Retirement Assets Last?

Sunday, December 2nd, 2007

It is a symptom of middle age that one begins to ponder the prospects of retirement and an occupational affliction of a scientist to marshal mathematics to consider this question. It is difficult to estimate how much income one needs upon retirement. There are many mitigating factors. A retired person is no longer contributing to Social Security and a retirement plan and so this portion of gross income can be dispensed with. The costs of commuting are no longer a factor and usually by the time of retirement one’s house has been paid for and children have left the home. On the other hand, idleness is not a hopeful retirement prospect. Engaging in activities such as travel introduce additional costs. For someone of modest retirement assets, Social Security will form a larger fraction of post-work income. At higher incomes, Social Security drops to a smaller fraction of the total expected income. For baby boomers, there is also the prospect that demographic trends will place strong downward pressure on Social Security payments, particularly for those whose may have other resources.

Here we put off the question of exactly how much income one needs and try to compute for a given amount of retirement assets, what is a reasonable spending level that will allow those assets to last a lifetime. There are two key factors to answering this question: (1) What is a reasonable rate of return on accumulated assets? (2) How much will inflation erode these assets. To answer this question, we performed a simple simulation, the results of which are shown below in Figure 1.


Figure 1. Retirement scenarios.

We begin the simulation with $1,000,000 in retirement assets. Any values we compute can easily be scaled based on actual assets. We also begin with the assumption that we can safely expect a long-term investment rate of return of 5%. We then assume that the first year we withdraw an income $40,000 (4% of the total). If we started with $2,000,000 in retirement assets, the yearly income would scale to $90,000.For the each subsequent year we increase the withdrawal amount by the inflation rate. Overtime, the $40,000 withdrawal gets nominally larger to maintain a real income of $40,000.

The blue curve starting at year 0 shows the remaining assets as a function of time for a 2% inflation rate (left scale). Note that for more than the first 25 years, there is actual growth in the nominal level of assets.

The other blue curve represents the nominal income as a function of time (right scale). After 40 years, the nominal income under this scenario would grow to nearly $90,000, but it would presumably purchase what $40,000 would have bought at the start of retirement.Note further, that after 40 years, there are sill significant assets remaining, nominally over $500,000. Assuming a retirement age of 65, retirement assets would still remain at age 105.

The red and yellow curves represent the results of similar scenarios assuming inflation rates of 3% and 4%, respectively. Even with a 3% inflation rate, we could maintain a $40,000 real income until age 100. At 4% inflation (or a real rate of 1% for a nominal 5% investment return), funds would last until age 95. In other words, if we can maintain real rates of return on our investment of 1% or greater, a retirement income of 4% of the original assets should should last a lifetime.

How reasonable is it to assume that such rates could last over the three or four decades of retirement? As Physicist Neils Bohr once quipped, “Prediction is very difficult, especially about the future.” If we knew with certainty future inflation rates, investment rates of return, and the number of years we would live, retirement planning would be substantially easier. We can, however, look at the past to determine whether our assumptions about the future are plausible.

Figure 2. Comparison of CPI-derived inflation rates with CD rates.

The yellow curve in Figure 2 is the inflation rate computed from the Consumer Price Index for Urban Areas (CPI-U) from the Bureau of Labor Statistics from 1913 to 2006 (left scale). There have been many oscillations in the past, yet over the last few decades these extremes seem to have modulated. The end of the 1970’s was the last time that we suffered under double-digit inflation. From the 1980’s to the present we have enjoyed inflation rates less that 5%, usually much less.

For our purposes here, the relationship between inflation rates and the nominal rates of return on safe investments is what matters. As long as the investment rate of return on accumulated assets is appreciably larger than the inflation rate, then inflation risks are alleviated. The blue curve inf Figure 2 represents the rate of return from an average of 3-month Certificate of Deport (left scale). Usually, but not always. CDs have rates of return greater than the inflation rate.The red curve is the difference between the CD and CPI-derived inflation rates (right scale). Since 1968, the period over which we have managed to find data, the difference between the two has averaged 2%. For the scenarios outlined in Figure 1, assuming an investment rate of return of 5% and inflation rate of 3% seems reasonable.

There are a number of factors which will mitigate inflation risks associated with retirement. First, a CD rate of return is about about as conservative as one can get. A slightly more aggressive investment strategy would likely improve the long-term investment rate of return. Moreover, the CPI is thought to overestimate the real inflation rate. We actually might be able to increase withdrawals from assets at a rate lower than the inflation rate and maintain the same standard of living. Finally, any retirement strategy need not be rigid. As the investment returns and inflation change, it is possible to alter the withdrawal strategies as accumulated assets increase or decrease unexpectedly.

Onward and Upward

Sunday, November 18th, 2007

Class warfare has never had the saliency in the United States that it has had in Europe. Part of the reason is that in the United States, it has largely been the case, that economic opportunity has been open to merit. There have been critical exceptions like slavery that ended over 140 years ago, Jim Crow in the South, and lingering discrimination. Nonetheless, economic success is as open to talent in the United States as anywhere. It is hard to rail against the rich if the audience aspires to become affluent at some point and this aspiration is realistic.

A recent report from the Department of Treasury confirms the nature of upward economic mobility in the United States. The study began with taxpayers in 1996 and followed their income as reported to the IRS as well as Social Security payments. Individuals were tracked even with joint returns to follow incomes after divorce. Only taxpayers older than 25 were considered in the original cohort because students can go from virtually no income to high income quickly and overstate actual income mobility. About 88% of the original taxpayers in 1996 could be tracked to 2005, with a large fraction of the attrition associated with the death of the taxpayer. Death generally has very negative effect on personal income.

Even separate from the question of mobility the study found the the entire economic escalator had risen several steps. For the group in question, the median real income had increased by 25 percent over 10 years.

Over the course of lifetime, people progress through at least some portion of the income distribution. Most start at a relatively low income, maximizing their income in middle age, living in retirement off Social Security and accumulated assets at at lower income level. The width of the income distribution is a snapshot of the dynamic movement within the distribution.

The study had several other key findings:

  • About one half of the original cohort in the bottom quintile moved into a higher income quintile during the study period.
  • A similar percentage moved from one quintile to another quintile during the 10-year study.
  • At the very tip of the income distribution, the top one-hundredth of one percent, only 25 percent of those in this group in 1996 remained there in 2005. It is not that these people were now poor, only that people occupy the very pinnacle of the income distribution for a short time.
  • Income mobility in this period is consistent with income mobility in early decades.
  • “…[T]he median incomes of those initially in the lower income groups increased more than the median incomes of those initially in the higher income groups.”

These results are consistent with previous studies showing intergenerational income mobility: i.e., that parental income is not a limiting factor to a child’s income. A University of Chicago study found that parental income explains only 37 percent of the child’s income. Extending to the next generation, the a grandparent’s income can explain only 14% of the variation in a grandchild’s income. There are very few hereditary limits on individuals in the United States.

As long as income mobility is maintained, the United States is likely to remain economically free, largely immune from populist animosity.

Liberty and Safety

Saturday, October 27th, 2007

Benjamin Franklin is often cited as the source of the observation, “They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.” Despite the fact that there is some dispute as to the origin of the quote, it remains a marvelously malleable remark, able to assume various meanings suitable for buttressing different political points.

Civil libertarians can call upon Franklin to support the argument that government should be hobbled in its intrusiveness even if by doing so may make the life of criminals a little easier. Those in favor a military force to fight forces of oppression can use Franklin to weigh on the side of liberty as opposed to the safety of acquiescence .

Nonetheless, there really is a balance between liberty and safety that must be struck. We are constantly told by our friends on the Left that the Patriot Act is poor trade off between safety and liberty. We put this argument off to another time, but point out here that there is another liberty and safety trade off that is at the heart of Conservative political philosophy: the balance between safety and economic liberty.

Civil liberties such as the freedom of speech, freedom of association, and privacy are defining elements of a free society, however, in terms of day-to-day activities, it is through economic freedom that we exercise control over our own lives. The economic resources at our disposal allow us to decide where to live, where to travel, what to eat, and what clothing to wear. Economic resources empower us to make the myriad of small choices that define how we live our lives. I may cherish my freedom of speech, but I enjoy economic freedom daily. To understand the importance of economic freedom just ask yourself if you had 10% greater or 10% fewer economic resources at your disposal how would the scope of your personal choices increase or decrease.

What Conservatives understand intuitively and what Liberals need to learn is that when people are taxed to provide resources for the state to ameliorate social problems, they are doing so at the cost of personal economic freedom. Just as some might exaggerate external threats to argue for reductions in civil liberties, others might exaggerate social problems to make the case for the reduction of economic liberty.

This is not to conclude that there ought not be any social programs or any government spending. Rather, it is to argue that we recognize that taxation entails a very real reduction of personal liberty. For Conservatives, the balance between taxation and the government modulation of the vagaries of a dynamic economy is tipped a little more to the side of economic freedom. We can steal from Franklin and assert “They that can give up economic freedom to obtain a little temporary safety deserve neither freedom nor safety.”

Calculating Global Warming Costs and Benefits

Sunday, October 14th, 2007

If asked how much is a human life, alleviating human suffering, or a child’s well-being is worth, most of us would rightly wince at the thought of placing any monetary value on these. We are instinctively moved to devote whatever resources are necessary to protect even a single human life, ease human suffering, or help a child. This natural and appropriate human response, however, does not alleviate us of the moral responsibility for proper stewardship of finite resources. Resources are always finite. If we spend too much to save a particular life, we may consume resources that if more judiciously applied could save many lives. While it may be distasteful to assert that a life is worth a specific number of dollars, we can say that protecting many lives deserves a higher priority than saving one life. Sometimes dollars provide a convenient mechanism for computing the number of lives that may be saved. Using such an approach we often find that it is more efficient to apply resources to preventative care than enormous resources at the end of life that may add only a few days of life. The scary part is that if we move to a socialized health care system, we find that it is government rather than individuals who balancing resources against lives. This, however, is another story.

Here we suggest the necessity of performing a similar cost-benefits analysis on dealing with the prospect of climate change. As much as we might wish to anything possible to alleviate the effects of climate change, This is an approach recently suggested by the “skeptical environmentalist” Bjorn Lomborg. While we may wish to do whatever we can to reduce climate change and its effects, since resources are finite, reason compels us to ask how best to use these resources.

What are the costs of proceeding along the same course we are currently pursuing versus the costs of attempting to abate climate change? Of course the specific answer depends on who you ask and what part of the world you are concerned about. In a recent paper, “The Distributional Impact of Climate Change on Rich and Poor Countries,” published in Environmental and Development Economics, Robert Mendelsohn, Ariel Dinar, and Larry Williams attempt to bound the problem. They use the predictions of three climate models spanning the range of conventional predictions. The models predict a global increase in temperatures by 2100 ranging from 2.5 degrees C to 5.2 degrees C. The predicted precipitation changes range from a 15.5 increase to a 5.6% decrease. The increases in sea level range from 0.3 to 0.9 m. Local changes in different continents, though less certain, show far more variability.

The authors then couple the local climate change predictions with the local economies to determine the effect of climate on global and regional gross national product. On balance, the tropical countries, that are already warm, suffer the most. As one might expect, poorer countries, both because they tend to be nearer the equator and have a larger fraction of their GDPs linked to agriculture, suffer typically experience the largest negative impact.

Globally the effect of climate change on GDP by 2100, depending on both the climate and economic model ranges from a positive 0.10% to a negative 0.13%. Since the world economy will be substantially larger than by 2100, a 0.13% reduction will be a lot of money but the per capita effect would seem to be small, perhaps even a net positive. This would suggest that only we should accept only tiny changes on GDP as a cost of climate change reduction. This conclusion is especially true if we cannot eliminate, but only modestly reduce the effects of climate change. Of course, this calculus would be different for certain areas that would be more severely impacted.

Resources devoted to climate change abatement should also be balanced against other uses of the same resources, including providing clean water and medical resources to impoverished areas.

The work by Mendelsohn et al. is by no means a conclusive assessment of the economic effects of climate change and there is always the small but non-negligible possibility that climate change could be dramatically greater than the current best estimates. Nonetheless, the balance of the costs and benefits of climate change abatement against other possible uses of finite resources constitutes the only rational terms defining the debate.

What About Those Higher Gas Prices?

Sunday, June 3rd, 2007

Willing the ends without willing the means is almost the very definition of puerile behavior. Nonetheless, this behavior is descriptive of the Democratic approach to the twin issues of climate change and gasoline prices. Al Gore and his environmental minions constantly remind us of imminent climate disaster posed by greenhouse gas emissions, much of it released from the tailpipes of our cars. The quickest way for us to move toward reduction of these emissions, either by developing and purchasing higher mileage cars or altering our traveling habits, is by increasing the price of gasoline. Indeed, the Clinton-Gore Administration modestly increased the federal gasoline taxes. On the other hand, higher gas prices automatically induce spasms of anti-oil company rhetoric. This is reflective of the internal contraction within the Democratic Party of populist rhetoric and the impulse to use the government to manage our lives for us.

Economist Robert Samuelson recently elaborated on the hypocrisy. Samuelson explained how the cause in the recent spike in gasoline prices is limited refining capacity. Because of low profit margins in this sector of the industry, refining capacity has not increased very much over the last few decades. In the early 1980’s, the US enjoyed an excess of refining capacity and partially as a consequence no new refinery has been built in the US since 1976. Recent increases in US refining capacity have been the product of modernization of existing facilities rather than the construction of new ones. Of that capacity, the US is currently using nearly 90%. It is not generally possible to run at 100% of capacity, given accidental stoppages and scheduled maintenance.

Some have argued that the oil industry has deliberately arranged to minimize refining capacity to force an increase in prices. Such activity is illegal, if it can be proved. Illegal restraint of trade seems unlikely, given that refining capacity in the US is not concentrated in one or two firms. Samuelson cites Michael Salinger of the Federal Trade Commission as describing the concentration in the oil refinery business as “low to moderate.” Moreover, foreign refinery capacity would tend to limit the ability of US refining firms to create artificial shortages. Given the stated governmental goals of reducing gasoline consumption over the next decade, it is not clear whether it makes economic sense for oil companies to make the long-term, large-scale capital investments in significant increases in refinery capacity.

Even if one could demonstrate that oil companies were artificially generating increases in prices, aren’t they doing what environmentalists want but to do but do not have the political power to execute? The only question seems to be whether the government is enriched by taxes or oil companies by windfall revenues, for consumers the effect is the same. High gas prices will push the US economy toward lower gasoline consumption, the stated goal of environmentalists.

The disheartening part is that despite the rhetoric, the higher gasoline prices we have experienced may decrease gasoline consumption but will have only have marginal, perhaps not even measurable, climatic impact over the next few decades. To have a significant effect would require rapid decreases in emissions, changes that are sufficiently aggressive that they would likely cause painful and disruptive economic transitions. Such transitions could stunt economic growth just when we need it to finance Social Security and Medicare for the baby boomers, and they would likely hurt the less affluent the most severely. This is the truth that Democrats are unwilling to acknowledge.

We are told we need to invest those renewable energy sources with less of a climatic impact. If such alternatives were available on a large scale and less expensive, we would have moved to them already. If they are more expensive, it means that no matter which way one cuts it, more personal resources will be used to pay for more expensive energy. Less money to be spent on everything else. Under normal free market economic circumstances, economic transitions make life better because there is a trend to move to the more efficient provision of goods and services. Government forces transitions are, almost by definition, inefficient.

Democratic partisan James Carville recently criticized the manner in which George Bush led us in the War on Terror because he did not involve most Americans directly in the cost of war. Bush did not raise taxes; rather he encouraged economic growth through tax cuts. He asked Americans to lead their lives normally and did require additional economic sacrifices. Carville argues that when you go to war you have to take the entire country to war. Everyone needs to feel the sacrifice [1]. If we take Carville at his word, should not Democrats be asking for sacrifices in the fight to save the planet? Too many subscribe to the illusion that by relatively modest efforts; people driving a few more Prius’s, coupled with a few more wind farms and solar panels, we can significant alter the climate change trajectory. Should not the true economic costs of the economic transformation required to deal with what Al Gore claims is the greatest global challenge of the age be made clear.

Ultimately, the argument made by those who advocate aggressive measures be taken to reduce climate change, is that the present, almost certain, negative economic consequences necessary to alleviate climate change are much smaller than the predicted negative consequences of not doing so. Honesty demands that such a case be made without minimizing current costs or maximizing future ones.

[1] Leave aside for a moment that the US won the Cold War by essentially economically outgrowing the Soviet Union. In a very real way, Americans won the Cold War not through economic retrenchment, but through the growth associated with business as normal. Maintaining economic strength is a necessary strategy in winning a war. What Carville is really complaining about is that Bush chose tax cuts rather than tax increases in order to invigorate the economy.

Disappearing Deficit

Sunday, February 18th, 2007

During the 2004 presidential elections, Democrats tried to persuade the American public that job creation was the worst since the Great Depression and the country was in a downward economic spiral. In order to make the case, Democrats had to employ statistics creatively. We could no longer look at the unemployment rate, the traditional measure, because it was too good. Instead, they used other Bureau of Labor statistics that notoriously lag the economic growth that was beginning even in 2003 and 2004.

There was a downturn beginning in late 2000 and early 2001 as the country entered a mild recession. This was cyclical response to the growth at the end of the 1990s and the collapse of the “Dot.Com Bubble.” Then after the terrorist attacks of September 11, the downturn grew deeper as the national mood soured and the stock market plunged. The combination of a loose money supply provided by the Federal Reserve and President Bush’s tax cuts pulled us back to prosperity. Inflation stayed low, unemployment fell, the economy roared back and since 2003 stock market values have reached new highs. In 2004, the fullness of the recovery was not yet as obvious as it is now. Democrats can no longer complain that the overall economy was not doing well. Instead, they have to try to provoke class warfare with erroneous complaints that the benefits of economic growth have not been wide spread. These statistics on income and wealth inequality cited are just as misleading that those previously used by Democrats to disguise rebounding employment.

There is at least one other economic index whose rebound has been hidden. One of the largest complaints by the Democrats now was that tax cuts increased the federal deficit. Now the size of the deficits may be large, they are not large with respect to the economy. Indeed, as a fraction of the Gross National Product (GNP) they have already been decreasing. Unfortunately, relative measures, though more meaningful, are more difficult to explain. It seems now that federal receipts are growing so rapidly that the nominal deficit may soon disappear and the one remaining Democratic economic complaint will evaporate.

The value of the nominal federal deficit over last decade is shown below. This is a plot of the twelve-month running average in the federal deficit in billions of dollars. The month-to-month numbers are noisy. Note, that the plot shown is a “following” running average. The value for the current month is the total deficit for the last 12 months. This plot would tend to be a lagging indicator.


Federal Deficit - 12-month running average
The combination of loose monetary policies, spending restraint and growth accounted for the surplus in the latter half of the 1990s, President Clinton’s second term. The year 2001 would have seen a decrease in the surplus in any case, but after September 11, the plunge was precipitous. The budget deficit reached its largest value at the end of 2003. Since then the deficit has been steadily disappearing. Steve Conover of the Skeptical Optimist has been carefully tracking the federal deficit. In his plot below, he fits a trend to the budget surplus/deficit data since January 2005. By his extrapolation, the nominal federal deficit should disappear in the middle of 2008.
Skeptical Optimist Projection
The exact point of zero deficit depends on precisely how one does the fit. If one begins the fit in January 2004 when the deficit first began to decrease, the crossover point to zero nominal deficit occurs in 2009. The longer the fit period, the more statistically significant the linear fit and projection are. However, the shrinking of the deficit has been accelerating and since the twelve-month running average is a lagging indicator perhaps Conover’s projection is most accurate. Conover concedes noisiness in the extrapolation of current trends. This collapse of the federal deficit is amazing and a testament to the power of tax cuts. The deficit is decreasing despite an expensive war in Iraq, a period of little spending restrain, and the introduction of prescription drug plan for seniors, a new entitlement. It suggests that rapid growth is perhaps the only realistic way of balancing the federal budget, whether in real or nominal terms. You can tell that the economy is doing well when Democrats stop talking about it.The Democrats’ position has been out-of-phase with reality: complaining about unemployment just as employment accelerates or complaining about the deficit just as it is about to disappear. Are they equally as out-of-phase with respect to other issues?You can tell that Iraq is not going well, or is at least perceived as not going well, when the Democrats incessantly talk about it. Unfortunately, Democrats now have a vested political interest in failure in Iraq. It is not that they really want failure, but they are in the uncomfortable position of knowing that good news for Americans in Iraq is bad news for Democratic political ambitions. If the surge of forces in Iraq works, Democrats may find themselves conspicuously wrong again — just before an election. They will then have to rely on the traditional method of concealing and ignoring success.

Income and Wealth

Sunday, January 21st, 2007

Paul Krugman, op-ed writer for the New York Times and economics professor at Princeton University, once boasted about his algebraic understanding. Whereas most political and social commentators speak or write of unquantifiable philosophical notions, coming from an economic background, Krugman is adept at algebraic symbol manipulation. Economists try to model their social science on the physical sciences like physics or chemistry, whose universal language is mathematics. Indeed, Krugman was correct in writing, “There are important ideas in [economics] that can be expressed in plain English, … [b]ut there are also important ideas that are crystal clear if you can stand algebra, and very difficult to grasp if you can’t.” Krugman concedes his impatience with those less precise in thought and presentation than he fancies himself to be. The danger, of course, is that after having postured so, someone will challenge Krugman on his own terms.

Alan Reynolds, of the Libertarian Cato Institute, did not write Income and Wealth as a specific rebuttal to Krugman. However, Krugman has been so argumentative and prolific in writing about the economic demise of the middle class and poor at the expense of the affluent and has done so via the exploitation of sloppy statistics that he provides convenient and oft-mentioned examples of the misuse of statistics. Krugman’s professional background makes it impossible to plausibly plead ignorance to their misuse. None one who seriously wants to understand income and wealth and how it has changed over time in the United States, can be ignorant of the concepts explained by Reynolds in Income and Wealth.

The fundamental problem for Liberal economists is history. In the 1970’s under a regime of high tax rates, the economy suffered high inflation, high interest rates, high unemployment, and low growth. Then President Ronald Reagan arrived and slashed marginal tax rates by half. After a relatively short transition period, the economy radically improved with high growth rates, low inflation, low interest rates, and low unemployment. Clinton marginally increased tax rates but only modestly and, with the help of a Republican Congress, passed the North American Free Trade Agreement (NAFTA). Clinton’s free trade policies were in direct conflict with trade unions, a traditional member of the Democratic electoral coalition. The economy was buoyant in the 1990s. After the short recession caused by the attacks of September 11, Bush’s tax cuts have revived the economy. Moreover, those industrialized countries in Europe that have adhered to a high-tax strategy, the policy advocated by Liberal economists, are burdened with low growth and high unemployment. The Conservative prescriptions for the economy are conspicuously successful.

The response from the Left is to concede the high growth, low unemployment, low inflation, and low interest rates; but to argue a series of “Yes, buts.” Yes, but the real median wages have remained static for the last twenty-five years. Yes, but only the rich have experienced increasing incomes as the expense of the poor. Yes, but the rich have increased their wealth more than others. Yes, but income and wealth inequality have grown.

Unfortunately for the rhetorical convenience of the Left, in order to make such claims, it is necessary to make any number of rather simple errors. Reynolds systematically explains the real nature of the data. For example:

Real wages have only remained static if you use an obsolete measure of inflation. With more modern measures, median wages have risen by over a third.

Median wages only include the wages of those who are employed. In the late 1970’s, the base period often used for comparisons, unemployment was high. The least skilled and the lowest paid were laid off first, ironically increasing median wages for those still employed during that period. However, no one would reasonably want to increase unemployment to increase median wages.

Wages measure only a part of compensation. Medical and retirement benefits have become an increasingly large part of total compensation. Counting only wages neglects this important component. Also ignored are transfer payments to the lower income quintile such as Social Security or in-kind assistance like food stamps.

The Gini index is a broad measure of inequality. People often point to the increase in inequality as measured by the Gini index during the 1990s. Of course, it is often neglected that for technical reasons the Census Department altered the way it computed the index in the early 1990s. This resulted in a one time jump in the Gini index that did not reflect any change in the economy. Without this jump, the Gini index has remained relatively stable.

In measuring the distribution of wealth, many studies only include immediately accessible wealth, i.e., liquid financial instruments. Counting in this ignores the enormous increase in the wealth of the middle class from increasing housing values and increasing asset value of 401(k) or 403(b) retirement plans.

In addition, the demographic composition of the United States has aged dramatically over the last two-and-half decades. Typically, young people are rich in human capital, with the prospect of earning income over many years. Older people have less human capital, but have accumulated a lifetime of assets and savings. By conventional measures, the older people are wealthier than younger ones. Changes in wealth distribution in large measure represent a change in the age distribution rather than a direct economic change.

Reynolds explains that the single biggest discriminator on which households occupy different income quintiles is the number of people who work in the household. Two income households fill the top quintile, while the bottom quintile usually has no worker or only a part-time worker, perhaps a single mother. Family structure is highly correlated with economic success.

The media is too full of glib and incorrect assertions about who has and has not benefited from explosive economic growth of the last two-and-half decades. Reynolds sorts through the errors and the rhetoric in a readable style. And in the end who could disagree with his conclusion:

“No matter what one thinks ought to be done about taxes, spending, unions, immigration, trade, minimum wage laws, and so on, the first thing that needs to be done is to get the facts right. If that happens there will still be plenty of room for lively debates about all sorts of public policies. And they will be honest debates.”
