A necessary and sufficient condition for the dominance of an improved family of estimators in linear regression models

This article presents a necessary and sufficient condition for the dominance, with respect to the risk under a general quadratic loss function, of the double k-class estimators (characterized by non-stochastic scalars) over the least squares estimator of coefficients in linear regression models.     

ACCOUNTING FOR HOUSEHOLD PRODUCTION: A PROTOTYPE SATELLITE ACCOUNT USING THE AMERICAN TIME USE SURVEY

This paper presents a satellite account where households are treated as production units. It extends previous work that treats consumer durables as investment and that values nonmarket household production activities such as cooking, cleaning, and childcare. Services from consumer durables and government capital related to household production are also valued. In constructing the updated accounts, this paper incorporates new time use data from the American Time Use Survey (ATUS) and the harmonized time use data from the Multinational Time Use Study (MTUS). This paper also discusses and incorporates recommendations made by the U.S. National Academies panel on nonmarket accounts.     

Dynamic effects of externalities,optimal saving and economic growth

Conclusion Recognizing the fact that provision of mixed public goods can result in both consumption externalities of the Samuelsonian variety as well as production externalities we set out to extend the earlier results of Rao and Kalpagam (1977) on the effect of public goods on economic growth. In so doing, we considered three standard specifications of production externalities and enlarged the concept of consumption displacement. Our basic conclusion is that the results of our earlier paper remain valid under the more general conditions set out in this paper.     

An Analysis of Differences in Earnings Between Small and Large Commercial Banks

This paper introduces a simple, yet rich, measure of efficiency changes based on the revenue-generating-ability (RGA) principle. Using this principle, we explain the connections between efficiency changes and the variables, such as pretax profits, interest expense, non-interest expense, profit margins, loan loss provision, and asset quality. These connections are used to explain earnings differences between small and large commercial banks.     

Too Much Competition in Higher Education? Some Conceptual Remarks on the Excessive‐Signaling Hypothesis

Within the economics of higher education, there is a small but influential literature that describes and analyzes the outcomes of competitive processes on markets for higher educational services. Colleges and universities in the United States currently invest a vast amount of resources in order to attract well-qualified students. Costly activities like advertising, infrastructure investments, the recruitment of academic stars, or the granting of merit-based tuition discounts can be interpreted as different forms of market signaling in the sense of Spence. According to some social science authors, these signaling activities have reached a dimension that has to be classified as excessive or socially wasteful from a welfare-economic viewpoint. The present article makes some conceptual remarks on this excessive-signaling hypothesis, and intends to contribute to the debate about the (potentially) harmful and beneficial effects of competition in higher education.     

Stereotypes, Asian Americans, and Wages: An Empirical Strategy Applied to Computer Use at Work

This article examines the effect on wages of the Asian-American stereotype as mathematically and technically adept, and the role this stereotype may play in explaining racial wage differences. We propose an empirical strategy to examine the influence of stereotypes on labor market outcomes, with a specific application to the wage premium associated with computer use at work. Using Current Population Survey data, ordinary least squares estimates do not provide compelling evidence that a positive stereotype affects wages for Asian Americans.     

Performance of French intensive care units: A directional distance function approach at the patient level

By using a novel adaptation of the free-disposable hull analysis of productivity, we assess the medical and technical efficiency of patient care in 25 Parisian intensive care units (ICUs) during 2000. The robust free disposable hull (RFDH) as defined by [Cazals et al., 2002. Nonparametric frontier estimation: a robust approach. Journal of Econometrics 106, 1–25] reduces the impact outliers may have on findings by employing Monte-Carlo techniques and repeated sample selection. Among our key findings, there was no overall significant correlation between medical and technical efficiencies for all the ICUs, therefore performing well in one does not guarantee good performance in the other. We also found that over 80% of inefficiency is concentrated in less than 20% of the sampled patients.     

A multivariate cointegrated model testing for temporal causality between exports and outward foreign investment: the Spanish case

Historically, outward foreign direct investment has been contemplated as an alternative way of firms' internationalization. In this line, a relational substitution between exports and foreign direct investment would be expected. However, this seems to contrast with recent developments in the ‘new trade theory’ which show that the volume of trade and the emergence of multinational firms may be positively related one to the other. This paper investigates if some empirical evidence exists either supporting a substitution or a complementary relationship between both forms of internationalization. With this aim, an aggregate time series approach was adopted using quarterly aggregate data (seasonal adjusted) from the Spanish economy covering the period 1970.I–1992.III. A vector autoregressive model was employed for both multivariate cointegration analysis and Granger temporal causality testing. The strength and direction of causal relationships are shown through the dynamic variance decomposition and the impulse response technique. Once controlling for relative market size and prices, the results provide evidence of a positive long-term Granger causality going from foreign direct investment to exports, although not in the opposite direction.
