We consider the problem of estimating and decomposing wage differentials in the presence of unobserved worker, firm, and match heterogeneity. Controlling for these unobservables corrects omitted variable bias in previous studies. It also allows us to measure the contribution of unmeasured...

This paper investigates the effects of a decrease in fixed costs on the division of labor within firms. In the constant markup rate model, a decrease in fixed costs curbs the division of labor. In the short run, the division of labor is promoted through labor reallocation within firms while in...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationshipbetween (i) the unemployment rate, (ii) the value of non-market time, and (iii) themax-mean wage differential. The latter measure of wage...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

Besides the theoretical approach, the paper also includes an research conducted with students of the Faculty of Jornalism and Communication at the University of Bucarest. The main objective of this research was to determine the extent to which the media fiction (television series for youth)...

Comparing labor markets of the United States and Germany over the period 1980 − 2004 uncovers three stylized differences: (1) transition rates from unemployment to employment (UE) were lower by a factor of 5 and inflow rates from employment to unemployment (EU) were lower by a factor of 4 in...

This paper looks at some of the fundamental ideas in contemporary economics such as the basic economic problem, opportunity cost and allocation a person is expected to encounter when they are first introduced to economic theory. It attempts to explain how the manner in which these concepts are...

In this paper, we propose a matching and search model with adjustment costs in the form of labor disruption charges that can generate counter-cyclical real wages. Empirically, we use a measure of wage cyclicality based on the generalized impulse response function of real wages to a shock in a...

An extensive empirical literature has documented that workers with high tenure suffer large and persistent earnings losses when they get displaced. We study the reasons behind these losses in a tractable search model with a life-cycle dimension, endogenous job mobility, worker- and...

In this paper, we explore the fluctuations of unemployment and vacancies in the Italian labour market over the last twenty years. For reasons of data availability on unfilled job openings, this period is split in two parts. The former is covered by a help-wanted time series, while the latter is...
