Disputes by their nature involve contentious behavior. If one attributes such behavior to underlying personality traits, these attributions can be quite damning. The current research investigated negative trait attributions and their impact on dispute resolution decisions. We hypothesized that judging one's opponent to be low in agreeableness and high in emotionality (e.g. stubborn and volatile) shifts one?s preference towards more formal procedures ? formal in the sense that a third party judge controls the process and outcome.

This paper presents an approach to modeling workers where human performance has a significant impact on system productivity. Highly technical industries such as semiconductor manufacturing and service industries like banking are relying on fewer but more skilled workers. In these systems, productivity depends on worker availability and organization; therefore, modeling system performance may require accurate representations of individual worker behavior.

We model the trade-off between low-asset risk and low leverage to satisfy preferences for low-risk deposits and apply it to interwar New York City banks. During the 1920s, profitable lending and low costs of raising capital produced increased bank asset risk and increased capital, with no deposit risk change. Differences in the costs of raising equity explain differences in asset risk and capital ratios. In the 1930s, rising deposit default risk led to deposit withdrawals. In response, banks increased riskless assets and cut dividends.

This paper examines transfer pricing in multinational firms when individual divisions face different income tax rates. Assuming that a firm decouples its internal transfer price from the arm's length price used for tax purposes, we analyze the effectiveness of alternative pricing rules under both cost- and market-based transfer pricing. In a tax-free world, Hirshleifer (1956) advocated that the internal transfer price be set equal to the marginal cost of the supplying division.

We analyze the Pareto optimal contracts between lenders and borrowers in a model with asymmetric information. The model generalizes the Rothschild-Stiglitz pure adverse selection problem by including moral hazard. Entrepreneurs with unequal "abilities" borrow to finance alternative investment projects which differ in degree of risk and productivity. We determine the endogenous distribution of projects as functions of the amount of loanable funds, when lenders have no information about borrowers' ability and technological choices.

In an environment where trading volume affects security prices and where prices are uncertain when trades are submitted, quasi-arbitrage is the availability of a series of trades that generate infinite expected profits with an infinite Sharpe ratio. We show that when the price impact of trades is permanent and time-independent, only linear price-impact functions rule out quasi-arbitrage and thus support viable market prices. When trades have also a temporary price impact, only the permanent price impact must be linear while the temporary one can be of a more general form.

We propose that consumers' investment decisions involve processes of promotion and prevention self-regulation that are managed across separate mental accounts, with different financial products seen as representative of promotion versus prevention.

Preference structures that underlie survey or experimental responses may systematically vary during the administration of such measurement. Maturation, learning, fatigue, and response strategy shifts may all affect the sequential elicitation of respondent preferences at different points in the survey or experiment. The consequence of this phenomenon is that responses and effects can vary systematically within the dataset.

This paper examines search across competing electronic commerce sites. By analyzing panel data from over 10,000 Internet households and three commodity-like products (books, CDs and air travel services), we show that the amount of online search is actually quite limited. On average, households visit only 1.2 book sites, 1.3 CD sites, and 1.8 travel sites during a typical active month in each category. Using probabilistic models, we characterize search behavior at the individual level in terms of (1) depth of search, (2) dynamics of search, and (3) activity of search.

Perspective-taking, by means of creating an overlap between self and other cognitive representations, has been found to effectively decrease stereotyping and ingroup favoritism. In the present investigation, the authors examined the potential moderating role of self-esteem on the effects of perspective-taking on prejudice. In two experiments, it was found that perspective-takers, but not control participants, with temporarily or chronically high self-esteem evaluated an outgroup more positively than perspective-takers with low self-esteem.

Teacher quality is widely believed to be important for education, depsite substantial but inconsistent evidence that teachers' credentials matter for student achievement. To accurately measure variation in achievement due to teachers' characteristics—both observable and unobservable—it is essential to identify teacher fixed effects while controlling for fixed student characteristics and classroom specific variables.

Griliches' 1994 presidential address considers the limited success economists had in trying to account for the productivity slowdown of the 1970s and 1980s and "urges us toward the task of observation and measurement." In the 1990s, the high rates of productivity growth emphasized the need for new models of productivity, this time turning to estimating organization-level determinants of productivity focusing on businesses' use of new computer-based information technologies (IT), and new methods of work organization (Timothy Bresnahan et al., 2002).

The question of whether higherlifetime income households save a larger fraction of their income was the subject of much debate in the 1950s and 1960s, and while not resolved, it remains central to the evaluation of tax and macroeconomic policies. We resolve this long-standing question using new empirical methods applied to the Panel Study of Income Dynamics, the Survey of Consumer Finances, and the Consumer Expenditure Survey.

How do people react to those who have helped them? The authors propose that a recipient's evaluation of a helper's intentions and the recipient's own attitudes about future interactions with the helper depend partly on the recipient's perceptions of how the helper decided to assist: on the basis of affect, of role, or of cost-benefit calculation.

Two experiments explored the hypothesis that the impact of activating gender stereotypes on negotiated agreements in mixed-gender negotiations depends on the manner in which the stereotype is activated (explicitly vs. implicitly) and the content of the stereotype (linking negotiation performance to stereotypically male vs. stereotypically female traits). Specifically, two experiments investigated the generality and limits of stereotype reactance.

We address infinite-horizon models for oligopolies with competing retailers under demand uncertainty. We characterize the equilibrium behavior which arises under simple wholesale pricing schemes. More specifically, we consider a periodic review, infinite-horizon model for a two-echelon system with a single supplier servicing a network of competing retailers. In every period, each retailer faces a random demand volume, the distribution of which depends on his own retail price as well as those charged by possibly all competing retailers.

We study estimation of the tail-decay parameter of the marginal distribution corresponding to a discrete-time, real-valued stationary stochastic process. Assuming that the underlying process is short-range dependent, we investigate properties of estimators of the tail-decay parameter which are based on the maximal extreme value of the process observed over a sampled time interval. These estimators only assume that the tail of the marginal distribution is roughly exponential, plus some modest "mixing" conditions.

Motivation research distinguishes two types of goals: (a) ideals, which relate to people's hopes, wishes, and aspirations, and (b) oughts, which relate to people's duties, obligations, and responsibilities. We propose that, in persuasion, the accessibility of ideals increases consumers' reliance on their subjective affective responses to the ad relative to the substance of the message, whereas the accessibility of oughts increases consumers' reliance on the substance of the message relative to their subjective affective responses.

The authors hypothesize that when managers integrate two projections to form a sales estimate, they evoke and use a sales range to judge inappropriately the plausibility of each projection. This judged plausibility, as well as the "margin of error" (based on the market research company's typical accuracy), is used to assign weights to each projection. Five experiments find strong evidence for this process and demonstrate a resulting bias.

The authors propose and test a new "polyhedral" choice-based conjoint analysis question-design method that adapts each respondent's choice sets on the basis of previous answers by that respondent. Polyhedral "interior-point" algorithms design questions that quickly reduce the sets of partworths that are consistent with the respondent’s choices. To identify domains in which individual adaptation is promising (and domains in which it is not), the authors evaluate the performance of polyhedral choice-based conjoint analysis methods with Monte Carlo experiments.

It is increasingly apparent that the financial value of a firm depends on intangible assets (e.g., brands, customers, employees, knowledge) that are not on the balance sheet. In this paper, we focus on the most critical aspect of a firm—its customers. Specifically, we demonstrate how valuing customers makes it feasible to value firms, including high growth firms with negative earnings.

This paper develops a stochastic general equilibrium model for an oligopoly, in which all inventory constraint parameters are endogenously determined. We propose several systems of demand processes whose distributions are dunctions of all retailers' prices and all retailers' service levels. We proceed with the investigation of the equilibrium behavior of infinite-horizon models for industries facing this type of generalized competition, under demand uncertainty.

High-dimensional problems frequently arise in the pricing of derivative securities—for example, in pricing options on multiple underlying assets and in pricing term structure derivatives. American versions of these options, i.e., where the owner has the right to exercise early, are particularly challenging to price. We introduce a stochastic mesh method for pricing high-dimensional American options when there is a finite, but possibly large, number of exercise dates.

We study linguistic access in a mixed language context by integrating the Bilingual Interactive Activation model and the Language Differential Processing model. We show that highly proficient bilinguals, compared to less proficient bilinguals, activate phonological and semantic representations of the dominant as well as the non-dominant language, and engage in differential processing for different types of scripts (phonetic vs. logographic). For highly proficient bilinguals, language emphasis (Chinese vs.
