The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor's share typically have relied on industry or macro data, obscuring heterogeneity among firms. In...

The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a "superstar firm" model where industries are increasingly characterized by "winner take most" competition, leading a small number of highly profitable (and low labor...

This paper examines the impact of an export market expansion created by the US-Vietnam Bilateral Trade Agreement (BTA) on competition among manufacturing firms in Vietnam's local labor markets. Using a nonparametric production function approach, we measure distortionary wedges between...

We build a model where firm size is a source of labor market power. The key mechanism is that a granular employer can eliminate its own vacancies from a worker's outside option in the wage bargain. Hence, a granular employer does not compete with itself. We show how wages depend on employment...

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment, and the political difficulties in implementing more extensive reform programs. We argue that the heart of...

Considering a finance constrained economy, we discuss the stabilization role of variable labour and capital income taxes under a balanced-budget rule in the presence of consumption externalities of the "keeping up with the Joneses" type. We find that sufficiently procyclical labor and/or capital...

We study the interactions between capital income tax and social security privatization in the context of rising longevity. In an economy with idiosyncratic income shocks, redistributive defined benefit social security provides some insurance against income uncertainty. This insurance comes at...

The elasticity of substitution between capital and labor (σ) is usually considered a "deep parameter". This paper shows, in contrast, that σ is affected by both globalization and technology, and that different intensities in these drivers have different consequences for the OECD and the...

Since the beginning of the Industrial Revolution, technological change has led to the automation of existing tasks and the creation of new ones, as well as the reallocation of labor across occupations and industries. These processes have been costly to individual workers, but labor demand has...
