This article analyzes the labor mobility and human capital accumulation of male immigrants from the former Soviet Union to Israel. We estimate a dynamic choice model for employment and training in blue‐ and white‐collar occupations, where the labor market randomly offered opportunities are affected by past choices. The estimated model accurately reproduces the patterns in the data. The estimated direct earning return to local training, local experience, and knowledge of Hebrew are very high, whereas imported skills have zero (conditional) return. The welfare gain from the impact of training on job offer probabilities is larger than its effect on wages. 相似文献

Influence of institutional environment on entrepreneurial intention: a comparative study of two countries university students 总被引:1,自引:0,他引:1

Institutional environment influences the perceptions of desirability and feasibility, society’s social and cultural environment,
such as beliefs, values and attitudes, conditions behaviour and decisions made by individuals. This research evaluates the
influence of institutional environment on entrepreneurial intention using a comparative analysis of different attitudes among
university students in two countries: Portugal and Spain. In particular, this study aims to examine the perceptions of desirability,
feasibility and intention toward the creation of one’s own business and how that variables influence the entrepreneurial intention
as compared these two different institutional contexts. Results revealed difference among attitudes toward entrepreneurship
in both countries. With respect to the perception of feasibility, the majority of students in Extremadura (Spain) consider
that it is easier to create a business in nowadays than it was several decades ago. However, from the students of Beira Interior
(Portugal) consider that it is more difficult. Furthermore, in Extremadura, the entrepreneurial intention is higher than in
Beira Interior. 相似文献

This paper explores the factors influencing the board composition of an international sample of commercial banks over the period 1996–2006. After considering the dual role of the board as monitor and advisor, our analysis shows that no one board composition is optimal for the banking industry and that any such recommendation could harm bank governance. Our results suggest that more complex banks that have a low ownership concentration and are headquartered in a civil law country should have larger and more independent boards.

The allocation problem for multivariate stratified random sampling as a problem of stochastic matrix integer mathematical programming is considered, minimizing the estimated covariance matrix of estimated means subject to fixed cost or fixed total sample size. With these aims the asymptotic normality of sample covariance matrices for each strata is established. Some alternative approaches are suggested for its solution. An example is solved by applying the proposed techniques. 相似文献

This study examines the relationships among the PMBOK® Guide, project performance, customer satisfaction, and project success by assessing the efficacy of management techniques, tools, and skills for implementing infrastructure and building construction. Experienced interviewees from private engineering firms and public agencies were asked to complete a questionnaire, and the responses were analyzed by means of a structural equation model. The analytical results indicate the appropriateness of prioritizing the practice of the PMBOK® Guide in the construction industry. This study contributes to the literature by providing insight into interactions among the PMBOK® Guide and construction project outcomes in engineering practices. Particularly, the “bidder's conference” and “procurement negotiations” are the priority techniques to minimize bidding and legal procurement problems. Moreover, the study recommends the use of “stakeholder analysis,” “communication requirements analysis,” and the “communication methods” to perform effective communication management. Although the conclusions are based on the sample collected in Taiwan, the research findings can be used by project managers and educators to tailor the PMBOK® Guide to their unique needs and to design effective training programs for construction specialists. 相似文献

This paper examines the degree of persistence in international monthly arrivals to Australia by using data disaggregated by tourism‐source countries. We employ two competing models, which are very general in the sense that they include (seasonal and non‐seasonal) unit roots as particular cases of interest. The first model is based on a long‐memory process in the non‐seasonal part of the series along with a short‐memory autoregressive (AR) seasonal structure. The second model is based on a long‐memory process for the seasonal structure of the series, the short‐term evolution being described through a non‐seasonal AR(1) process. Results based on the residuals and forecasting assessment indicate that the second model is preferable in terms of fitting the data. We provide persistence ranking of all countries included in the study and discuss the managerial implications of the main findings. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This paper proposes a new model to discover customer value of air passengers by using data mining technologies. The results of this research can be applied in database marketing systems. The procedure applies See5/C5.0 (RuleQuest Research Pty Ltd, St Ives, New South Wales, Australia) decision tree; transaction records; Frequency, Price Discount, Destination and No‐Show (FPDN model; Recency, Frequency and Monetary model based) model variables; and socio‐economic variables to create decision rules for airline business. An empirical case of air passengers' market in Taiwan is implemented for the identification of this procedure and the Frequency, Price Discount, Destination and No‐Show model.

This article seeks to square two seemingly contradictory strands in the literature on economic development in the late nineteenth‐century Habsburg Empire. On the one hand, there is an extensive historiography stressing the rise of nationalism and its close correlate of growing efforts to organize economic life along ethno‐linguistic lines. On the other, there is a substantial body of research that emphasizes significant improvements in market integration across the empire as an outcome of the diffusion of industrialization and an expanding railway network, among other factors. In this article, it is argued that the process of market integration was systematically asymmetric, shaped by intensifying intra‐empire nationality conflicts. While grain markets in Austria‐Hungary became overall more integrated over time, they also became systematically biased: regions with a similar ethno‐linguistic composition of their population came to display significantly smaller price gaps between each other than regions with different compositions. The emergence and persistence of this differential integration cannot be explained by changes in infrastructure and transport costs, simple geographical features, asymmetric integration with neighbouring regions abroad, or communication problems. Instead, differential market integration along ethno‐linguistic lines was driven by the formation of ethno‐linguistic networks due to intensifying conflict between groups—economic nationalism mattered. 相似文献
