Reservation Raises: The Aggregate Labour Supply Curve at the Extensive Margin
Preston Mui, Benjamin Schoefer
Review of Economic Studies,
forthcoming
Abstract
We measure desired labour supply at the extensive (employment) margin in two representative surveys of the U.S. and German populations. We elicit reservation raises: the percent wage change that renders a given individual indifferent between employment and nonemployment. It is equal to her reservation wage divided by her actual, or potential, wage. The reservation raise distribution is the nonparametric aggregate labour supply curve. Locally, the curve exhibits large short-run elasticities above 3, consistent with business cycle evidence. For larger upward shifts, arc elasticities shrink towards 0.5, consistent with quasi-experimental evidence from tax holidays. Existing models fail to match this nonconstant, asymmetric curve.

A Congestion Theory of Unemployment Fluctuations
Yusuf Mercan, Benjamin Schoefer, Petr Sedláček
American Economic Journal: Macroeconomics,
No. 1,
2024
Abstract
We propose a theory of unemployment fluctuations in which newhires and incumbentworkers are imperfect substitutes. Hence, attempts to hire away the unemployed during recessions diminish the marginal product of new hires, discouraging job creation. This single feature achieves a ten-fold increase in the volatility of hiring in an otherwise standard search model, produces a realistic Beveridge curve despite countercyclical separations, and explains 30–40% of U.S. unemployment fluctuations. Additionally, it explains the excess procyclicality of new hires’ wages, the cyclical labor wedge, countercyclical earnings losses from job displacement, and the limited steady-state effects of unemployment insurance.

European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Journal of the European Economic Association,
No. 2,
2023
Abstract
This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Stubborn Core Inflation – Time for Supply Side Policies
The leading economic research institutes have raised their forecast for growth in German economic output in the current year to 0.3%. In the fall, they were still expecting a decline of 0.4%. “The economic setback in the winter half-year 2022/2023 is likely to have been less severe than feared in the fall. The main reason for this is a smaller loss of purchasing power as a result of a significant drop in energy prices,” says Timo Wollmershäuser, Head of Forecasts at ifo. Nevertheless, the rate of inflation will fall only slowly from 6.9% last year to 6.0% this year.
