What Makes the Difference? Microfinance Versus Commercial Banks
Afsheen Abrar, Iftekhar Hasan, Rezaul Kabir
Borsa Istanbul Review,
No. 4,
2023
Abstract
We make a comparison of microfinance banks (MBs) and commercial banks (CBs) in terms of efficiency, business orientation, stability, and asset quality by analyzing a large sample of banks from 60 countries around the world. Our findings indicate that microfinance banks have higher intermediation, non-interest income, wholesale funding and liquidity, but lower efficiency and asset quality. These significant variations are influenced by smaller microfinance banks and are driven mostly to African and Latin American microfinance banks.

Marginal Jobs and Job Surplus: A Test of the Efficiency of Separations
Simon Jäger, Benjamin Schoefer, Josef Zweimüller
Review of Economic Studies,
No. 3,
2023
Abstract
We present a test of Coasean theories of efficient separations. We study a cohort of jobs from the introduction through the repeal of a large age- and region-specific unemployment benefit extension in Austria. In the treatment group, 18.5% fewer jobs survive the program period. According to the Coasean view, the destroyed marginal jobs had low joint surplus. Hence, after the repeal, the treatment survivors should be more resilient than the ineligible control group survivors. Strikingly, the two groups instead exhibit identical post-repeal separation behavior. We provide, and find suggestive evidence consistent with, an alternative model in which wage rigidity drives the inefficient separation dynamics.

Minimum Wages, Productivity, and Reallocation
Mirja Hälbig, Matthias Mertens, Steffen Müller
IZA Discussion Paper,
No. 16160,
2023
Abstract
We study the productivity effect of the German national minimum wage by applying administrative firm data. At the firm level, we confirm positive effects on wages and negative employment effects and document higher productivity even net of output price increases. We find higher wages but no employment effects at the level of aggregate industry × region cells. The minimum wage increased aggregate productivity in manufacturing. We do not find that employment reallocation across firms contributed to these aggregate productivity gains, nor do we find improvements in allocative efficiency. Instead, the productivity gains from the minimum wage result from within-firm productivity improvements only.

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.
