This paper develops a multi-period model, in which workers are matched with jobs according to imperfect educational signals and in which their subsequent productivities depend on both their inherent ability and on the quality of the job match. It outlines a sequential process, in which underpaid...

This paper utilizes the self-employed to analyze the observed increase in the educational earnings premium in the 1980?s. The paper compares the predictions of the signaling and human capital models in response to an exogenous demand shock such as a skill-biased technological change. Since the...

This paper investigates whether education is used as a signaling device for worker productivity in developing countries. To do such we employ a simple test of employer learning on Ghana manufacturing data. We find no evidence of educational signaling for individuals who were hired through direct...

This paper presents a test of the educational signaling hypothesis. If employers use education as a signal in the hiring process, they will rely more on education when less is otherwise known about applicants. We find that employers are more likely to lower educational standards when an...

In my asymmetric-information model of layoffs, high-productivity workers are more likely to be recalled to their former employer and may choose to remain unemployed rather than to accept a low-wage job. In this case, unemployment can serve as a signal of productivity, and duration of...

The academic circles are devoting a growing interest to delayed graduation and overeducation, but none has analyzed the joint consequences of these two phenomena. Thus, this paper studies the link between graduation not within the minimum period and overeducation, and the effects of these...

This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

Assessing the migration potential and predicting future migration streams are among the most relevant, yet least well understood topics of migration research. The usual approach taken to address aggregate-level prediction problems is to fit ad hoc specifications to historical data, and to...

The current economic crisis requires fast information to predict economic behavior early, which is difficult at times of structural changes. This paper suggests an innovative new method of using data on internet activity for that purpose. It demonstrates strong correlations between keyword...

An important issue in the analysis of cross-sectional dependence which has received renewed interest in the past few years is the need for a better understanding of the extent and nature of such cross dependencies. In this paper we focus on measures of cross-sectional dependence and how such...
