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...

This paper offers the first study of job polarization in Great Britain using workplace level data. We document widespread and increasing occupational specialization within establishments, along with substantial heterogeneity in specialization within industries. Changes in the specialization...

This study considers the economic impact of Covid-19 on enterprises in four Central American countries – El Salvador, Guatemala, Honduras and Nicaragua. At the time of the analysis neither the pandemic nor its economic consequences had fully run their course. It is not, therefore, a definitive...

This paper explores the importance of firm dynamics, including entry and exit and the allocation of carbon emissions across firms, on the green transition. Using the 2000–2019 firm-level register data on greenhouse gas emissions matched with the Financial Statement data in the Finnish...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

Multinational labor demand responds to wage differentials at the extensive margin, when a multinational enterprise (MNE) expands into foreign locations, and at the intensive margin, when an MNE operates existing affiliates across locations. We derive conditions for parametric and nonparametric...

This note provides a useful property of the Allen-Uzawa partials for the translog cost function. It also suggests how the main results extend to any functional form with certain properties. The curvature of the Allen-Uzawa matrix is the same as the curvature of the Hessian matrix. Intuitively...

Skill-biased technical change is usually interpreted in terms of the efficiency parameters of skilled and unskilled labor. This implies that the relative productivity of skilled workers changes proportionally in all tasks. In contrast, we argue that technical changes also affect the curvature of...
