For more than one hundred years, economists have discussed the concept of positional goods—that the utility conferred by many, perhaps even most, goods depends not only on the amount the individual consumes, but also on the amount others consume (e.g., Thorstein Veblen, 1899; James Duesenberry, 1949; John K. Galbraith, 1958; Robert Frank, 1985). While economic interest in “positional goods” is increasing (e.g., Mark Pingle and Mike Mitchell, 2002; Kenneth Arrow et al., 2004; Ed Hopkins and Tatiana Kornienko, 2004), the literature remains largely theoretical rather than empirical. If status concerns affect all items in the utility function equally (leisure as well as goods), the positional effect would operate like a lump-sum tax, reducing well-being without changing the allocation of time or money (Arrow et al., 2004). However, if positional concerns are stronger for some things than for others, then in order to understand how people can become better off in well-being, not simply in wealth, we must investigate how interpersonal competition interacts with material gains (Frank, 1997). Evidence about what goods are more positional than others is essential for correct policy recommendations (Gregory Besharov, 2002), but little is actually known about the relative positional rankings of items in the typical consumer’s utility function. Four hypotheses proposed in the literature are:

Different beliefs about the fairness of social competition and what determines income inequality influence the redistributive policy chosen in a society. But the composition of income in equilibrium depends on tax policies. We show how the interaction between social beliefs and welfare policies may lead to multiple equilibria or multiple steady states. If a society believes that individual effort determines income, and that all have a right to enjoy the fruits of their effort, it will choose low redistribution and low taxes. In equilibrium, effort will be high and the role of luck will be limited, in which case market outcomes will be relatively fair and social beliefs will be self-fulfilled. If, instead, a society believes that luck, birth, connections, and/or corruption determine wealth, it will levy high taxes, thus distorting allocations and making these beliefs self-sustained as well. These insights may help explain the cross-country variation in perceptions about income inequality and choices of redistributive policies.

In the United States, two-thirds of the nonelderly population is covered by employerprovided health insurance (EHI). According to a Kaiser Family Foundation national survey (2003), the cost of EHI has increased by over 59 percent since 2000 with no accompanying increase in the scale or scope of benefits. These increases in health insurance premiums may have significant effects on labor markets, including changes in the number of jobs, hours worked per employee, wages, and compensation packages. Indeed, it is possible that a significant portion of the increase in the uninsured population may be a consequence of employers shedding this benefit as health insurance premiums rise. Understanding how labor-market characteristics affect adjustments to increased health insurance costs is of vital policy importance. Some proposals to cover the uninsured rely on “employer mandates” requiring employers to cover eligible workers. Other proposals provide tax credits for the purchase of non-employer health insurance. The effects of these proposals on employment, wages, and health insurance coverage will be driven by the elasticities of labor supply and demand, institutional constraints on wages and compensation packages, and how much workers value the increase in health insurance costs. Since employers provide such coverage voluntarily, if workers fully value these benefits and are able to sort between firms based on their preferences, then (in the absence of other institutional constraints) they will bear the cost of the increase via reduced wages, with no accompanying change in employment, employment costs, or employee utility. There are many reasons to believe, however, that firms are limited in their ability to offset increases in the price of health insurance premiums through lower compensation, so that increases in the cost of providing health insurance may affect both employment and the structure of work. Identifying the magnitude of these effects empirically is difficult both because of data availability and because of multiple avenues for causality. In this paper we uncover the causal effect of increases in the cost of benefits on labor-market outcomes by exploiting an exogenous source of variation in the cost of providing health insurance: the recent “medical malpractice crisis” in which malpractice costs for physicians grew dramatically in some states but not in others. The growth in malpractice payments affects malpractice insurance premiums and health insurance premiums, but it should not affect other aspects of employment (see Baicker and Chandra, 2005b). Using this source of variation, we examine the effect of increases in health insurance premiums on employment patterns, earnings, and health insurance coverage. We find that the cost of increases in health insurance premiums is borne in large part by workers through increased unemployment and also through decreased hours for those workers moved from full-time jobs with benefits to parttime jobs without. These results have strong implications for the distributional impact of health-care reforms. * Both authors: Economics Department, Dartmouth College, 6106 Rockefeller Hall, Hanover, NH 03755, Dartmouth Medical School, and National Bureau of Economic Research (e-mails: [email protected], achandra@ dartmouth.edu).

A $1 increase in the value of fringes may be offset by a $1 reduction in wages—or a $1/(1 tax rate) reduction for tax-favored benefits. For example, Jonathan Gruber (1994) demonstrates that the passage of the Pregnancy Discrimination Act in 1978 resulted in employers shifting the entire cost of the mandate onto employees.

On 1 October 2002, the State of Alaska increased taxes on malt beverages from $0.35 per gallon to $1.07 per gallon, increased taxes on wine from $0.85 per gallon to $2.50 per gallon, and increased taxes on distilled spirits from $5.60 per gallon to $12.80 per gallon. The net effect is that the tax on a standard serving rose from about 3 cents for beer, 2 cents for wine, and 4 cents for spirits to a uniform tax of 10 cents per standard serving of each type of alcohol beverage. This paper uses primary data on alcoholic beverage prices in Alaska to study a very basic question: What was the impact of the tax hikes on prices? An alcohol tax hike is often viewed as a public health policy tool to discourage excessive alcohol consumption and alcohol-related problems such as drunk driving. The impact of a tax hike on alcoholic beverage prices is a key link in the chain of the causality from the tax to public health. Economic theory and previous empirical studies, mainly of taxes on goods other than alcoholic beverages, do not provide very much guidance on what to expect following a tax hike. It is an empirical question. To answer the question, I conducted telephone surveys, just before and a year after the tax hike, of on-premise and off-premise alcohol retail establishments across Alaska.

This paper argues that the textbook search and matching model cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies in response to shocks of a plausible magnitude. In the United States, the standard deviation of the vacancy-unemployment ratio is almost 20 times as large as the standard deviation of average labor productivity, while the search model predicts that the two variables should have nearly the same volatility. A shock that changes average labor productivity primarily alters the present value of wages, generating only a small movement along a downward-sloping Beveridge curve (unemploymentvacancy locus). A shock to the separation rate generates a counterfactually positive correlation between unemployment and vacancies. In both cases, the model exhibits virtually no propagation.

In recent financial crises and in recent theoretical studies of them, abrupt declines in capital inflows, or sudden stops, have been linked with large drops in output. Do sudden stops cause output drops? No, according to a standard equilibrium model in which sudden stops are generated by an abrupt tightening of a country?s collateral constraint on foreign borrowing. In this model, in fact, sudden stops lead to output increases, not decreases. An examination of the quantitative effects of a well-known sudden stop, in Mexico in the mid-1990s, confirms that a drop in output accompanying a sudden stop cannot be accounted for by the sudden stop alone. To generate an output drop during a financial crisis, as other studies have done, the model must include other economic frictions which have negative effects on output large enough to overwhelm the positive effect of the sudden stop.
