Exports,borders, distance,and plant size

The fact that large manufacturing plants export relatively more than small plants has been at the foundation of much work in the international trade literature. We examine this fact using Census microdata on plant shipments from the Commodity Flow Survey. We show that the fact is not entirely an international trade phenomenon; part of it can be accounted for by the effect of distance, distinct from any border effect. Export destinations tend to be farther than domestic destinations, and large plants tend to ship farther distances even to domestic locations compared with small plants. We develop an extension of the Melitz (2003) model and use it to set up an analysis with model interpretations of ratios between large plant and small plant shipments that can be calculated with the data. We obtain a decomposition of the overall ratio into a term that varies with distance, holding fixed the border, and a term that varies with the border, holding fixed the distance. The distance term accounts for more than half of the overall difference.     

A behavioral theory of governments’ ability to make credible commitments to firms: The case of the East Asian paradox

An expansive literature exists linking institutional constraints, credible commitments, and economic growth. Yet, this literature runs into difficulty when it tries to explain the East Asian “paradox:” rapid economic growth achieved by countries with low levels of formal constraints on government discretion. We use a behavioral theory of commitment to argue that the characteristics of the salient actors (governments) and their actions (policies) affect the credibility of their behaviors in ways independent of the structural underpinnings of a country’s political institutions. This behavioral theory of commitment provides a distinct but complementary lens through which to view the apparent paradox presented by these East Asian countries, and more generally provides an alternative theoretical mechanism to explain and predict governments’ ability to credibly signal their commitment to a course of action to investing firms. The success of East Asian countries in encouraging investment from both domestic and foreign firms implies that firms interpret governments’ actions as credible signals of their intention to honor their commitments to firms, consistent with the behavioral theory of commitment.     

International Equity and Differentiation in Global Warming Policy

ne of the major obstacles to reaching a comprehensive agreement on global warming is the setting of greenhouse gas emission reduction targets for individual countries. Long-standing tensions between industrialized and developing countries have raised the issue of equity in burden-sharing. Moreover, individual industrialized nations have pleaded special circumstances and have sought differentiation in their obligations. This paper analyzes alternative rules for distributing tradable carbon dioxide emissions permits. A non-linear programming model, which distinguishes between allocation-based and outcome-based rules, is used to analyze the relative welfare outcomes. The model is applied to the world body of nations and yields several important policy implications.     

An exploratory study of determinants for restaurant servers’ actual tip earnings: Individual characteristics and work conditions

This exploratory study investigates two different types of determinants for servers’ actual tip earnings (individual characteristics versus work conditions) using readily available organizational data. Unlike previous studies that measured servers’ tips by asking subjects (servers or customers) to report tip amounts, we measure the actual tip earnings of each server extracted from the point of sale system. The results show that work conditions (daily work hours, weekend work hours, and immediate supervisors’ characteristics) have stronger relationships with servers’ tip earnings than servers’ individual characteristics (gender, tenure, and job satisfaction). This study represents an initial attempt to use objective data to measure servers’ tip earnings and explore its potential relationship with work conditions compared to its relationships with individual characteristics which have been frequently examined in previous studies.     

Sign This Agreement Not to Compete or You're Fired! Noncompete Agreements and the Public Policy Exception to Employment at Will

A California jury recently awarded an employee who was fired for refusing to sign a noncompete agreement $1.2 million in damages for wrongful discharge. Whether employees have a right to refuse to sign unenforceable noncompete agreements is an emerging employment law issue. This article considers whether a wrongful discharge remedy is available in such cases under the public policy exception to the employment-at-will doctrine. State court decisions addressing the question are conflicting. Some courts have allowed employers to discharge employees who refuse to sign a noncompete agreement even if the agreement is unreasonable. Other courts have recognized a claim for damages under the public policy exception. This article explores the issue from policy and managerial perspectives, critically analyzing the policy justifications advanced by the courts in those decisions, and comments on the liability risks to employers and the proper resolution of the issue.     

Variable Selection for Portfolio Choice

We study asset allocation when the conditional moments of returns are partly predictable. Rather than first model the return distribution and subsequently characterize the portfolio choice, we determine directly the dependence of the optimal portfolio weights on the predictive variables. We combine the predictors into a single index that best captures time variations in investment opportunities. This index helps investors determine which economic variables they should track and, more importantly, in what combination. We consider investors with both expected utility (mean variance and CRRA) and nonexpected utility (ambiguity aversion and prospect theory) objectives and characterize their market timing, horizon effects, and hedging demands.
