Decision Making & Negotiations

We study a model of imperfect competition and limited production capacity, in which a choice of low product quality enables firms to increase total production. We find that in the presence of limited capacity, such reduced quality often results in increased social welfare. We also explore the relation between the extent of competition and the choice of quality. We find that, in some cases, reduced competition leads to increased production, decreased average quality, increases total welfare, and makes consumers better off.

Does country transparency affect international portfolio investment? We examine this question by constructing new measures of transparency and by making use of a unique microdata set on portfolio holdings of emerging market funds around the world. We distinguish between government and corporate transparency. There is clear evidence that funds systematically invest less in less transparent countries. Moreover, funds have a greater propensity to exit nontransparent countries during crises.

Mental state inferences - judgments about what others think, want, and feel - are central to social life. Models of such "mind-reading" have considered main effects, including social projection and stereotyping, but have not specified the conditions that govern when these tools will be used. This paper develops such a model, claiming that when perceivers assume an initial general sense of similarity to a target, they engage in greater projection and less stereotyping. Three studies featuring manipulations of similarity supported this claim.

This empirical investigation tests the hypothesis that the benefits of personal choosing are restricted to choices made from among attractive alternatives. Findings from vignette and laboratory studies show that, contrary to people's self-predictions, choosers only proved more satisfied than non-choosers when selecting from among liked alternatives. When selecting from among disliked alternatives, the reverse is observed - that is, non-choosers proved more satisfied with the decision outcome than choosers.

The contribution of the feelings-as-information hypothesis to our understanding of the role of affect in judgment and decision making is discussed. Basic principles and regularities in how affective feelings guide judgments and decisions are then identified. Based on these principles and regularities, it is argued that the role of feelings in judgment and decision making may be more adaptive than has been assumed in most academic circles.

The Millennium Date Change (often referred to as Y2K) was anticipated to be a major liquidity event by many financial and corporate institutions as well as the central banks around the world. The timing of the event was foreseeable and thus satisfies the assumptions in the economic theory on public provision of private liquidity. We apply the theory to understand the liquidity premium in financial markets and the actions of the U.S. central bank in the period surrounding Y2K.

Participants in 401(k) retirement plans violate the basic principle of diversification by investing significant fractions of their savings in their employers' equity. This paper characterizes investors' active changes to their company stock investment over time by analyzing new inflows and transfers. The average investor seems to base active changes on salient information, paying attention to past returns, volatility, and business performance.

Many fundamental questions in oligopoly models reduce to the analysis of the monotonicity properties of various performance measures under the model's Nash equilibrium, with respect to specific exogenously specified parameters. These strategic parameters may have an impact on the demand functions of the various competitors, their cost structures or both.

In asset pricing models, the uncertainty surrounding firm fundamentals plays a central role, driving expected returns, volatility, and valuation ratios. In this paper, we extract estimates of the uncertainty embedded in earnings announcements using option prices. To do this, we take seriously the fact that the timing of earnings announcements, although not the response of equity prices, is known in advance. We develop a no-arbitrage option pricing model incorporating jumps on earnings announcement dates.
