How Should the Graduate Economics Core be Changed?

The authors present suggestions by graduate students from a range of economics departments for improving the first-year core sequence in economics. The students identified a number of elements that should be added to the core: more training in building microeconomic models, a discussion of the methodological foundations of model-building, more emphasis on institutions to motivate and contextualize macroeconomic models, and greater focus on econometric practice rather than theory. The authors hope that these suggestions will encourage departments to take a fresh look at the content of the first-year core.     

Analyzing the Market for Imported Cheese in Mexico

Rapid growth of U.S. dairy exports to Mexico began even before the 1994 North American Free Trade Agreement (NAFTA) and has been fueled by rapid population increases coupled with an expanding Mexican economy. This study uses a nonlinear approximate almost ideal demand system (NLAIDS) to estimate own and cross-price elasticities in the Mexican cheese import market to better understand market behavior and to assess the comparative position of the UnitedStates relative to other cheese market participants. Results of this study imply that attributes of cheese play a strong role in the composition of Mexican cheese import market.     

Linear SAM models for inequality changes analysis: an application to the Extremadurian economy

Social accounting matrices are adequate databases for the economic modelling. These matrices emphasize the role of households in the economy, and so, they usually disaggregate the household sector into several groups. This disaggregation allows social accounting matrices to be used for diverse income distribution analysis. The objective of this work is to use the linear SAM models to study how inequality is modified by several exogenous injections of income. The set of multipliers and indicators presented is applied to the economy of Extremadura – a region situated in the southwest of Spain. In particular, together with the accounting multipliers, two redistributed income matrices are presented to show how changes in final demand and in income transfers cause opposite effects in inequality. For contrasting these results, Gini and Theil indices are also used. Finally, a major reduction in both would result from an appropriate re-allocation of transfers.     

How former business owners fare in the labor market? Job assignment and earnings

This study uses detailed longitudinal matched employer–employee data to examine the impact of entrepreneurial experience on job assignments, careers, and wages. The results suggest that there are significant differences in career mobility between former business owners and workers who were always wage employees. Former business owners enter firms at higher job levels and progress faster up the hierarchy than wage employees without entrepreneurial experience. The majority of the former business owners find jobs in small firms. The return to business ownership experience is lower than the return to wage employee experience, thus suggesting that the labor market imposes a penalty for business ownership experience.     

Outliers - robust ECM cointegration tests based on the trend components

The main goal of this paper is to analyze the behavior of the ECM non-cointegration test when there are additive outliers in the time series under different co-breaking situations. We show that the critical values of the usual ECM test are not robust to the presence of transitory shocks and we suggest a procedure based on signal extraction to bypass this problem. These procedure renders ECM tests with a left tail of distribution under the null that is robust to the presence of additive outliers in the series. The small sample critical values and the empirical power of the test are analyzed by Monte Carlo simulations for several low frequency filters. The proposed empirical methodology is applied to the CPI-based US/Finland real exchange rate.JEL Classification: C22, C12, C15, C52, C51 Corresponding author: Alvaro EscribanoWe thank A.

Human resources audit

Human resource management (HRM) has experienced a strong evolution. In order to provide useful information to managers, it is necessary to evaluate the results generated by the design and implementation of personnel policies. This is the goal of the HR audit that includes two different analyses and valuations: the HR policies and their level of fit with the strategy of the firm, and the characteristics of human capital. Several criteria have been used to assess different HR policies. Nevertheless, the measurement of the value that human capital brings to the firm is a very complex topic. Consequently, different models are being presented that aim to properly solve this challenge. This paper will analyze the HR function from two perspectives: the evaluation of the implemented policies and the quality of human capital in relation to real competencies, and the capability to learn and develop new skills.     

Learning,non-equilibrium beliefs,and non-pecuniary payoffs in an experimental game

Summary. We present a parametric learning model of players' dynamic and possibly out-of-equilibrium beliefs about other players' preferences that also incorporates random utility (noise). We estimate the model using the data from the four-country ultimatum game experiments of Roth et al. (1991). We find evidence that in the US and in Israel, the estimated beliefs of proposers are stationary and out-of-equilibrium, that in Slovenia, they are in equilibrium, and that in Japan, they are out-of-equilibrium, change from period to period and move away from equilibrium over time. In Japan and in the US, the estimated proposers' beliefs are further away from the uniform prior than the estimated equilibrium beliefs. The results seem to provide support for a non-pecuniary payoff explanation in all countries.

Beware of the Watchdog: Rethinking the Normative Justification of Gatekeeper Liability

One of the prevailing explanations of the corporate scandals of the Enron era and the recent financial crisis is the failure of professional gatekeepers—such as auditors, corporate lawyers, and securities analysts—to detect and disrupt corporate misconduct. The alleged solution to this failure—typically proposed and justified on consequentialist grounds—is to impose legal liability on professionals. The purpose of this paper is to critically examine the normative foundations of gatekeeper liability. In the course of this paper, I shall defend the claim that gatekeeper liability may be morally objectionable not only on grounds of fairness but also on consequentialist grounds. The expected contribution of this paper is threefold. First, it systematizes the framing and moral justification of gatekeeping duties. Second, it calls into question the normative underpinnings for targeting intermediaries instead of primary wrongdoers. Third, it anticipates some negative (and often overlooked) results of gatekeeping strategies in the accounting profession, specifically in the realm of clientele selection, the expectation gap, and auditor compensation.     

POVERTY IN MEXICO DURING ADJUSTMENT

The paper analyzes the changes in poverty in Mexico during the 1980s adjustment program. We decompose poverty into its distribution and growth components, as well as by population subgroups, in order to illustrate the causes of the deterioration in the standard of living of the poorest of the poor. We suggest a transformation of the methodology by Datt and Ravallion (1992), to determine the likelihood of future compensation for those sectors of the population which suffered higher social costs derived from the contractionary policies. The importance of this exercise, is that it shows that contractionary measures may provoke deep structural transformations in an economy, which can make it more difficult to eradicate poverty in a reasonable time horizon.
