This paper develops new estimates of flows into and out of unemployment that allow for unobserved heterogeneity across workers as well as direct effects of unemployment duration on unemployment-exit probabilities. Unlike any previous paper in this literature, we develop a complete dynamic...

This paper explores the role that unobserved heterogeneity within an observed category plays in the dynamics of disaggregate unemployment and in the cross-sectional differences across individuals of the duration of unemployment spells. The distribution of unobserved heterogeneity is...

In this paper, I test the savings accumulation conjecture that is used to rationalize return migration decisions in the context of immigrants in Germany. Using cross-country and time variation in purchasing power parity, I distinguish between the two competing capital accumulation conjectures...

In this paper I test the capital accumulation conjecture that is used to rationalize return migration decisions in the context of immigrants in Germany and examine how labor market outcomes influence return migration decisions, with particular attention to selection in these outcomes in return...

We explore in this paper how trading noise, when considered as a market friction, reacts to trading activity. Transactions cost is a good explanation for intraday trading behavior in the market according to our data. Particularly, we show that in general trading brings friction to market....

We analyze in this study investor trading behavior based not on information related assumptions but on the search model of Vayanos and Wang (2007). Our study shows that search cost dictates trading polarization across investors, firm size and time of day. We find that individual investors prefer...

We analyze in this study what could have caused herding in the stock market. Information cascades have often been considered as a major cause. However, we present in this study evidences inconsistent with that hypothesis. Our analysis is in support of an alternative theory based on search cost...

This study tests the hysteresis hypothesis of unemployment in fourteen OECD countries by examining the stationarity of unemployment rates using several panel unit root tests. Empirical results show that the hysteresis hypothesis cannot be rejected for majority of the OECD when the tests are...

We attempt to identify in this paper the role of trading noise as a transactions cost to market participant in the sense of Stoll (2000), especially in the presence of trading concentration. Applying the measures of Hu (2006) and Kang and Yeo (2008), we analyze the noise proportion in intraday...
