TAX-RATE UNCERTAINTY, FACTOR SUPPLIES, AND WELFARE

Uncertainty about prospective changes in tax rates may increase factor supplies, and hence the tax base, permitting a reduction in tax rates that could result in a net increase in welfare. Under empirically relevant assumptions about attitudes towards risk we find that when an individual exclusively saves or works, the tax base rises in response to greater tax-rate uncertainty, so that welfare could indeed increase. However, when an individual both saves and works, the supply of the randomly taxed factor declines with increased uncertainty, implying that tax revenue and welfare decrease when the nonrandom tax rate is sufficiently low.     

SHORT‐TERM E‐PROCUREMENT STRATEGIES VERSUS LONG‐TERM CONTRACTS

In this paper we compare the following procurement strategies based on their expected costs: strategic partnership, which is based on a long‐term relationship with a single supplier; online search, which is a short‐term strategy; and a combined strategy, which is some combination of the first two strategies. In addition, we determine for the online search and combined strategy the optimal number of suppliers to contact for a price quote, and analyze how it depends on the various cost and demand parameters. The main contribution of this paper is that it does not assume a single procurement strategy, but rather compares three alternatives.     

GUNS AND OIL: AN ANALYSIS OF CONVENTIONAL WEAPONS TRADE IN THE POST‐COLD WAR ERA

This paper analyzes the global conventional weapons trade between 1989 and 1999. We postulate that a key reason for the huge transfer of weapons to the Persian Gulf region is the enormous value of the oil wealth there along with the dependence of Western economies on access to the relatively cheap and steady supply of crude oil. We find a strong, positive, and robust empirical association between arms trade and crude oil trade and explain it as the result of a target price band arrangement that was responsible for the remarkably stable crude oil prices during our study period.

The Meaning and Meaningfulness of Corporate Social Initiatives

In response to pressures to be more “socially responsible,” corporations are becoming more active in global communities through direct involvement in social initiatives. Critics, however, question the sincerity of these activities and argue that firms are simply attempting to stave off stakeholder pressures without providing a corresponding benefit to society. By drawing on institutional theory and resource dependence theory, we consider what factors influence the adoption of a “meaningful” social initiative—an initiative that is sustainable and has the potential for a significant positive impact on society—as opposed to a symbolic initiative. In addition, we raise the question of how social initiatives—both meaningful and symbolic—participate in the “institutional war” over the meaning of corporate social responsibility.
