ECONOMISTS generally take tastes as given and work out consequences of changes in prices, incomes, and other variables under assumption that tastes do not change. When pressed, either they engage in ad hoc theorizing or they explicitly delegate discussion of tastes to sociologist, psychologist, or anthropologist. Unfortunately, these disciplines have not developed much in way of systematic usable knowledge about tastes. Although economists have been reluctant to discuss systematically changes in structure of tastes, they have long relied on assumptions about basic and enduring properties of tastes. Self-interest is assumed to dominate all other motives,' with a prominent place also assigned to benevolence toward children2 (and occasionally others), and with self-interest partly dependent on distinction and other aspects of one's position in society.3 The dominance of self-interest and persistence of some benevolence have usually been explained by nature, or an equivalent evasion of problem. The development of modern biology since mid-nineteenth century and of population genetics in twentieth century made clear that is only beginning, not end of answer. The enduring traits of human (and animal) nature presumably were genetically selected under very different physical environments and social arrangements as life on earth evolved during millions of years. It is not difficult to understand why self-interest has high survival value under very different circumstances,4 but why should altruistic behavior, sometimes observed among animals as well as human beings, also survive? This kind of question has been asked by some geneticists and other biologists especially during last two decades. Their work has recently been christened sociI For example, Adam Smith said, We are not ready to suspect any person of being defective in selfishness [9, 1969, p. 446], and it is not from benevolence of butcher, brewer, or baker, that we expect our dinner, but from their regard to their own interest [10, 1937, p. 14]. 2According to Alfred Marshall, . . men labor and save chiefly for sake of their families and not for themselves [6, 1920, p. 228]. 3Nassau Senior said, the desire for distinction . . . may be pronounced to be most powerful of human passions [8, 1938, p. 12]. 4Ronald Coase argues convincingly that Adam Smith, especially in his Moral Sentiments, was groping toward an explanation of importance of selfinterest in terms of its contribution to viable social and economic arrangements (see Coase [5, 1976]).

Abstract Two influential papers in the tax‐avoidance literature (Desai and Dharmapala ; Desai, Dyck, and Zingales ) argue that aggressive forms of tax avoidance employ technologies that complement managerial rent extraction, and provide supporting evidence from firms in Russia. Several papers rely on this theory to motivate and interpret tests in a U.S. setting, but these tests are open to multiple interpretations. This paper investigates the extent to which shareholders of U.S. companies are affected by any such rent extraction. The evidence is inconsistent with the tax‐avoidance technologies employed by U.S. firms allowing managers to extract sufficient rents to negatively affect future performance. Additional tests on poorly governed U.S. firms find no evidence that tax‐avoidance activities relate positively to either overinvestment or higher executive compensation, and no evidence that either complexity or the Sarbanes‐Oxley Act moderates the relation between future performance and tax avoidance. The evidence suggests that caution is warranted in interpreting evidence according to this theory in a U.S. setting.

In addition to being a function of traditional fundamentals such as cash-flow persistence and the discount rate, the equilibrium association between a security price and a value-relevant statistic can simply be a function of what rational investors believe the association will be. We refer to this phenomenon as beliefs-driven price association (BPA). By explicitly considering the phenomenon of BPA, we show that the price response to information releases can vary over time even if the risk-free interest rate and investor preferences are static and the earnings/cash flow generating process is stable. This observation suggests, for example, that price-to-earnings associations and price volatility can vary over time even if a stable pattern of economic fundamentals suggests otherwise. The possibility of BPA suggests that measures of the cost of capital, information content, and growth prospects inferred from observed market prices will be confounded. While we do not predict when periods of BPA will arise, we provide empirically testable predictions about how prices should behave during periods of BPA. In particular, we predict that, during sufficiently long periods of high (positive or negative) BPA, price volatility, price levels, and expected returns will be higher than would be implied by a fundamental valuation framework. Finally, while BPA in the pricing of one security does not cause BPA in the pricing of other securities, the price levels of those other securities will be affected if the securities with BPA are sufficiently large relative to the market as a whole.

Using an integrated model to control for simultaneity, as well as new risk measurement techniques such as Adapted Exposure CoVaR and Marginal Expected Shortfall (MES), we show that the aggregate systemic risk exposure of financial institutions is positively related to sovereign debt yields in European countries in an episodic manner, varying positively with the intensity of the financial crisis facing a particular nation. We find evidence of a simultaneous relation between systemic risk exposure and sovereign debt yields. This suggests that models of sovereign debt yields should also include the systemic risk of a country's financial system in order to avoid potentially important mis-specification errors. We find evidence that systemic risk of a country's financial institutions and the risk of sovereign governments are inter-related and shocks to these domestic linkages are stronger and longer lasting than international risk spillovers. Thus, the channel in which domestic sovereign debt yields can be affected by another nation's sovereign debt is mostly an indirect one in that shocks to a foreign country's government finances are transmitted to that country's financial system which, in turn, can spill over to the domestic financial system and, ultimately, have a destabilizing effect on the domestic sovereign debt market.

A major aspect of social policy in the United States during the 1960's was the effort to increase employment and lessen the extent of poverty. The effects of these efforts, in particular those of the Manpower Development and Training Act, have been discussed by economists solely within the framework of empirical cost-benefit analysis. In this note we take a different approach to the study of manpower programs. Under a set of admittedly restrictive assumptions we analyze the relative efficiencies in reducing unemployment of several alternative subsidy programs. It should be remembered that the reduction of unemployment is merely one goal of these programs and that the usefulness of our result must be qualified accordingly.

Using micro-data from 48 developing countries, this article studies changes in cross-sectional patterns of fertility and child investment over the demographic transition. Before 1960, children from larger families obtained more education, in large part because they had richer and more educated parents. By century's end, these patterns had reversed. Consequently, fertility differentials by income and education historically raised the average education of the next generation, but they now reduce it. Relative to the level of average education, the positive effect of differential fertility in the past exceeded its negative effect in the present. While the reversal of differential fertility is unrelated to changes in GDP per capita, women's work, sectoral composition, or health, roughly half is attributable to rising aggregate education in the parents' generation. The data are consistent with a model in which fertility has a hump-shaped relationship with parental skill, due to a corner solution in which low-skill parents forgo investment in their children. As the returns to child investment rise, the peak of the relationship shifts to the left, reversing the associations under study.

Do consumers boycott in response to international conflict? We show that during the 2003 U.S.-France dispute over the Iraq War, the market share of French-sounding, U.S. supermarket brands declined. The dispute was a negative shock to U.S. consumers’ associations with France. French-sounding brands, which consumers perceive to be French imports but are not, allow us to isolate the dispute’s effect on economic behavior, as these brands’ only link to France is through consumers’ associations. Our estimates, derived from a nationwide sample of weekly supermarket sales for over 8, 000 brands, are robust to a variety of alternate explanations. We also show that supermarkets with a higher proportion of customers who are U.S. citizens (i.e., who more strongly identify with the U.S. national identity) exhibited sharper boycotts.

We find that PIPE issues that do not provide any protections to investors convey positive information about the firm and result in positive announcement period returns. However, PIPE issues that provide protections do not convey any new information about the firm and hence do not result in significant positive or negative announcement period returns. PIPE issuers that offer no protections to investors outperform their matched portfolios for up to 9 months after the issue. PIPE issuers that offer protections underperform their matched portfolios for 18 to 36 months after the issue.
