Time to learn? The organizational structure of schools and student achievement

Utilizing parametric and nonparametric techniques, we asses the impact of a heretofore relatively unexplored ‘input’ in the educational process, time allocation, on the distribution of academic achievement. Our results indicate that school year length and the number and average duration of classes affect student achievement. However, the effects are not homogeneous – in terms of both direction and magnitude – across the distribution. We find that test scores in the upper tail of the distribution benefit from a shorter school year, while a longer school year increases test scores in the lower tail. Furthermore, test scores in the lower quantiles increase when students have at least eight classes lasting 46–50 min on average, while test scores in the upper quantiles increase when students have seven classes lasting 45 min or less or 51 min or more.     

WHO BENEFITS FROM JOB CORPS? A DISTRIBUTIONAL ANALYSIS OF AN ACTIVE LABOR MARKET PROGRAM

Using recently developed econometric techniques to estimate quantile treatment effects (QTE) and experimental data, we examine the impact of Job Corps on earnings distribution. Our results indicate a great deal of heterogeneity in the effects of Job Corps. The QTEs show an increasing pattern along the earnings distribution, with much more pronounced differences at the upper quantiles for males, whites, and ages 20–24. Moreover, we find the QTEs to be very small at quantiles below the median for males, ages 16–17 and 18–19, and non‐resident students. We propose strong economic conditions and skill hypotheses to explain the heterogeneity observed over the earnings distribution. Copyright © 2013 John Wiley & Sons, Ltd.     

Export Performance: Is It Possible through Knowledge and Capabilities? Evidence from Turkish Manufacturing Firms

Purpose: This article measures to what extent export performance is affected by certain resource-based view (RBV) elements and seeks to elucidate relationships between these elements. Design: Among those RBV elements, knowledge and experience as resources, and marketing, production, product development, logistics, and service differentiation as capabilities, are chosen to be the basis of this research. Their effects on export performance are measured with a survey applied to personnel of Turkish manufacturing firms operating in Istanbul district. Findings: The results show us that marketing planning capabilities and service differentiation capabilities have a significant effect on export performance. The overwhelming effect of knowledge and experience of firms on marketing planning capabilities is one of the intriguing findings. Notwithstanding that, we found no trace of a relationship between product development capabilities and service differentiation capabilities. Value: This research provides several managerial and academic implications by contributing to a resource-based view in terms of knowledge and capabilities. Additionally, in this study, it is underlined that collective knowledge is vital for achieving high export performance.     

Estimating Euler equations with noisy data: two exact GMM estimators

In this paper we exploit the specific structure of the Euler equation and develop two alternative GMM estimators that deal explicitly with measurement error. The first estimator assumes that the measurement error is log‐normally distributed. The second estimator drops the distributional assumption at the cost of less precision. Our Monte Carlo results suggest that both proposed estimators perform much better than conventional alternatives based on the exact Euler equation or its log‐linear approximation, especially with short panels. An empirical application to the PSID yields plausible and precise estimates of the coefficient of relative risk aversion and the discount rate. Copyright © 2008 John Wiley & Sons, Ltd.     

R&D tax incentives: a reappraisal

This paper examines R&D tax incentives in oligopolistic markets. We characterize the conditions under which tax incentives reach the socially desirable level of firm-financed R&D spending. The outcome of the market depends not only on the level of technological spillover in the industry but also on the degree of strategic interaction between the firms. One major result emerges from the model: The socially desirable level of R&D investment is not necessarily reached by subsidizing R&D. When the technological spillover is sufficiently low, the government might want to tax R&D investments, and this result does not necessarily arise because firms are overinvesting in R&D. There are also cases in which an R&D tax is desirable even though firms are underinvesting in R&D compared with the first-best optimum. In practice, this theoretical finding calls for a lower sales tax combined with an R&D subsidy in oligopolistic industries with high technological spillovers, and a lower sales tax combined with an R&D tax in oligopolistic industries with low technological spillovers.     

Entry costs and stock market participation over the life cycle

Several explanations for the observed limited stock market participation have been offered in the literature. One of the most promising is the presence of market frictions mostly in the form of fixed entry and/or transaction costs. Empirical studies point to a significant structural (state) dependence in the stock market entry decision, which is consistent with costs of this type. However, the magnitude of these costs is not yet known. This paper focuses on fixed stock market entry costs. I set up a structural estimation procedure which involves solving and simulating a life cycle intertemporal portfolio choice model augmented with a fixed stock market entry cost. Important features of household portfolio data (from the PSID) are matched to their simulated counterparts. Utilizing a Simulated Minimum Distance estimator, I estimate the coefficient of relative risk aversion, the discount factor and the stock market entry cost. Given the equity premium and the calibrated income process, I estimate a one-time entry cost of approximately two percent of the permanent component of the annual labor income. My estimated model matches the zero median holding as well as the hump-shaped age–participation profile observed in the data.     

How and when do prior international experiences lead to global work? A career motivation perspective

While research suggests a link between individuals' prior international experiences and their future participation in global work, we know little about how and the conditions under which this relationship occurs. Drawing on career motivation theory, we conceptualize global identity as a mediator between individuals' density of prior international experiences—defined as the extent to which time spent in culturally novel countries has provided individuals with developmental opportunities—and their global work aspirations, which in turn leads to their global work involvement. Further, this multi-stage mediation model holds mainly when individuals receive positive feedback regarding their intercultural competencies (i.e., cultural intelligence) from their peers. We test our model using a multi-wave multi-source dataset spanning 6 years. We discuss implications for the literatures on prior international experiences and global careers.     

Does the law of one price hold in a high-inflation environment? A tale of two cities in Turkey

This study addresses the price convergence in two cities in Turkey (Istanbul and Ankara) using annual data over the three-quarters of the twentieth century (1922–1998), characterized by prevailing high inflation rates for most of the period. In contrast to the rest of the literature addressing convergence in price levels with a typical result of extremely slow convergence rates at best, we argue that convergence is much easier detected in growth rates rather than levels of prices. We suggest using the bounds testing procedure of Pesaran et al. (2001) for this purpose. We find a clear-cut evidence on the existence of a common driving force behind inflation dynamics in Istanbul and Ankara – a finding that is in contrast with the results typically reported in related literature.     

Revenue management for make-to-order manufacturing systems with a real-life application

Abstract

Due to successful applications of revenue management in the airline industry, in recent years, there has been a growing interest to adopt revenue management in make-to-order (MTO) manufacturing systems. Several interrelated decision problems such as order acceptance/rejection, short-term capacity planning, due date assignment, and order scheduling need to be studied simultaneously in order to manage revenues effectively in MTO manufacturing systems. Both the producer’s and customer’s requirements need to be taken into account through some negotiation mechanisms that are sensitive to the service-level reputation of the manufacturing companies. In this article, we propose a new dynamic bid price–based revenue management model that considers all of the aforementioned decision problems simultaneously. A simulation optimization approach is utilized in order to determine the best possible values of control parameters for bid price, due date assignment, and price increment/reduction mechanisms. The performance of the proposed integrated revenue management model is tested on both a hypothetical example and a real problem of a bridal gown company. The computational results show that the proposed model provides significant improvements in total revenue compared to other static and dynamic bid price policies.     

How Ethical Behavior of Firms is Influenced by the Legal and Political Environments: A Bayesian Causal Map Analysis Based on Stages of Development

Even though potential impacts of political and legal environments of business on ethical behavior of firms (EBOF) have been conceptually recognized, not much evidence (i.e., empirical work) has been produced to clarify their role. In this paper, using Bayesian causal maps (BCMs) methodology, relationships between legal and political environments of business and EBOF are investigated. The unique design of our study allows us to analyze these relationships based on the stages of development in 92 countries around the world. The EBOF models structured through BCMs are used to explain how EBOF in a given country group are shaped by how managers perceive political, legislative, and protective environments of business in these countries. The results suggest that irregular payments and bribes are the most influential factors affecting managers’ perceptions of business ethics in relatively more advanced economies, whereas intellectual property protection is the most influential factor affecting managers’ perceptions of business ethics in less-advanced economies. The results also suggest that regardless of where the business is conducted in the world, judicial independence is the driving force behind managers’ perceptions of business ethics. In addition, the results of this study provide further support for scholars who argue that business ethics is likely to vary among countries based on their socio-economic factors. In addition to its managerial implications, the study provides directions for policy makers to improve the ethical conduct of businesses in their respective countries.
