This paper develops a model of costly firm creation in an economy with weak institutions, costly business environment as well as skill gaps where one of the equilibrium outcomes is a low-productivity trap. The paper tests the implications of the model using a cross-sectional dataset including...

In this paper, we show that the wage assimilation of immigrants is the result of the intricate interplay between individual skill accumulation and dynamic equilibrium effects in the labor market. When immigrants and natives are imperfect substitutes, increasing immigrant inflows widen the wage...

This paper brings together the modern literatures on monopsony power and labor unions by empirically examining the effects of unionization on the dynamics of worker earnings across differently concentrated markets. Exploiting tax reforms to union due deductions as exogenous shocks to...

As skills of labor-market entrants are usually not directly observed by employers, individuals acquire skill signals. To study which signals are valued by employers, we simultaneously and independently randomize a broad range of skill signals on pairs of resumes of fictitious applicants among...

The paper introduces a model of enterprise formation in a unionized economy with labor protection and wage bargaining. Enterprise formation is subject to future market risk and is shaped by labor market institutions in the post-entry stage. The predictions of the model are tested in...

We argue that the narrative of variety-induced gains from trade in differentiated goods needs revision. If producing differentiated varieties of a good requires differentiated skills and if the work force is heterogeneous in these skills, then firms are likely to have monopsony power. We show...

We develop a model that combines monopolistic competition on goods markets with skill-type heterogeneity on the labor market to analyze the effects of trade and migration on welfare and inequality. Skill-type heterogeneity and partial specificity to firms' endogenously chosen skill requirements...

We study the effects of a voluntary skill certification scheme in an online freelancing labour market. We show that obtaining skill certificates increases freelancers' earnings. This effect is not driven by increased freelancer productivity but by decreased employer uncertainty. The increase in...

For emerging professions, such as jobs in the field of Artificial Intelligence (AI) or sustainability (green), labour supply does not meet industry demand. In this scenario of labour shortages, our work aims to understand whether employers have started focusing on individual skills rather than...
