European Firms after the Crisis – New Insights from the 5th Vintage of the CompNet Firm-level-based Database

Elena Ashtari Tafti Richard Bräuer Sante De Pinto Marco Grazioli Matthias Mertens Daniel Stöhlker Marta Tagliabue

2016

Abstract

This report intends to shed light on the competitive stance of European firms after the crisis. In line with CompNet cutting-edge approach, we take a firm-level perspective to analyse the competitive position of European firms by drawing from the new vintage of the firm-level-based CompNet database. This micro-level approach allows us to ascertain the extent in which firms performances are heterogeneous across EU, also in relation of possible determinants of such performance.

Die Wirkungen von Handelsliberalisierungen: Ein Vergleich zwischen dem Melitz-Ansatz und der endogenen Wachstumstheorie

Matthias Mertens

in: Springer Gabler, Wiesbaden, 2016

Abstract

Matthias Mertens diskutiert Vor- und Nachteile des Melitz- und des endogenen Wachstumsansatzes hinsichtlich der Analyse von (Wohlfahrts-)Effekten einer Handelsliberalisierung und zeigt, dass beide Ansätze eine Daseins-Berechtigung besitzen, da sie verschiedene Handelsliberalisierungsaspekte in den Fokus setzen. Die Arbeit ermöglicht eine einfache Modellauswahl für die Analyse relevanter handelspolitischer Fragestellungen und Anwendungsfälle. Weiterhin verdeutlicht der Autor das Zukunftspotential hybrider Ansätze, welche endogene Wachstumsmodelle und Melitz-Modelle miteinander kombinieren und zur Entwicklung einer generalisierten Modelltheorie für die Analyse von Handelsliberalisierungswirkungen beitragen können.

Labour Market Power and the Distorting Effects of International Trade

Matthias Mertens

in: IWH Discussion Papers, No. 18, 2018

Abstract

This article examines how trade shocks shape labour market imperfections that create market power in labour markets and prevent an efficient allocation of labour. I develop a framework for measuring such labour market distortions in monetary terms and document large degrees of those distortions in Germany’s manufacturing sector. Import competition can only exert labour market disciplining effects when firms rather than workers have labour market power. Otherwise, export demand and import competition shocks tend to fortify existing distortions by amplifying labour market power structures. This diminishes the gains from trade compared to a model with perfectly competitive labour markets.
