After the Ban: The Japanese Market for U.S. Beef, April 2007

In the months following the reopening of the Japanese market to imports of U.S. beef on July 26, 2006, Japanese importers were unable to procure adequate supplies. This paper discusses reasons for early supply shortages and some of the policy and trade issues that will affect demand for U.S. beef in the short to medium term. The paper also discusses current marketing efforts for domestic and imported beef, new marketing technologies, and general consumer trends. The information presented in this paper includes on-site observations and data from meetings with Japanese importers and retailers and industry experts during market research in Tokyo and Osaka in November 2006.

On the impact of fundamentals, liquidity and coordination on market stability

We develop a coordination game to model interactions betweenfundamentals and liquidity during unstable periods in financial markets.We then propose a flexible econometric framework for estimationof the model and analysis of its quantitative implications. The specificempirical application is carry trades in the yen dollar market, includingthe turmoil of 1998. We find a generally very deep market, withlow information disparities amongst agents. We observe occasionallyepisodes of market fragility, or turmoil with up by the escalator, downby the elevator patterns in prices. The key role of strategic behaviorin the econometric model is also confirmed.

The optimal length of contracts with application to outsourcing

This paper resolves three empirical puzzles in outsourcing by formalizing the adaptationcost of long-term performance contracts. Side-trading with a new partner alongside a long-term contract (to exploit an adaptation-requiring investment) is usually less effective than switching to the new partner when the contract expires. So long-term contracts that prevent holdup of specific investments may induce holdup of adaptation investments. Contract length therefore trades of specific and adaptation investments. Length should increase with the importance and specificity of self-investments, and decrease with the importance of adaptation investments for which side-trading is ineffective. My general model also shows how optimal length falls with cross-investments and wasteful investments.

Improved estimation of the covariance matrix of stock returns with an application to portofolio selection

This paper proposes to estimate the covariance matrix of stock returnsby an optimally weighted average of two existing estimators: the samplecovariance matrix and single-index covariance matrix. This method isgenerally known as shrinkage, and it is standard in decision theory andin empirical Bayesian statistics. Our shrinkage estimator can be seenas a way to account for extra-market covariance without having to specifyan arbitrary multi-factor structure. For NYSE and AMEX stock returns from1972 to 1995, it can be used to select portfolios with significantly lowerout-of-sample variance than a set of existing estimators, includingmulti-factor models.

KemapMobile: una adaptación de la herramienta software KeMap a la plataforma Android

Este trabajo describe el proceso de creación de la herramienta de software KemapMobile para la plataforma Android. El artefacto es una adaptación del software de escritorio KeMap que se integra en la plataforma educativa VerilUOC y permite a los estudiantes conectarse a ella para descargar, en la aplicación, ejercicios con los que poner a prueba y afianzar sus conocimientos sobre la simplificación de funciones lógicas booleanas con mapas de Karnaugh y tablas de verdad. La arquitectura cliente-servidor de la aplicación permite a los estudiantes disponer de ejercicios personalizados y al profesorado obtener datos sobre el uso de la herramienta y sobre la progresión del alumnado.
