IWH-CompNet Discussion Papers
Die IWH-CompNet Discussion Papers beinhalten Forschungsergebnisse auf Basis von Daten zur Produktivität, die durch das Competitiveness Research Network (CompNet) bereitgestellt werden. Das internationale Netzwerk verfolgt das Ziel, einen einheitlichen Analyserahmen zu entwickeln, mit dessen Hilfe Produktivität und Wettbewerbsfähigkeit eingeschätzt werden können. Die Papiere ermöglichen den Zugang zu den Forschungsergebnissen von CompNet in einer vorläufigen Fassung, zu der Kommentare und Empfehlungen vor der endgültigen Veröffentlichung gern angenommen werden.
Price-cost Margin and Bargaining Power in the European Union
in: IWH-CompNet Discussion Papers, Nr. 4, 2019
Using firm-level data between 2004 and 2012 for eleven countries of the European Union (EU), we document the size of product and labour market imperfections within narrowly defined sectors including services which are virtually undocumented. Our findings suggest that perfect competition in both product and labour markets is widely rejected. Levels of the price-cost margin and union bargaining power tend to be higher in some service sectors depicting however substantial heterogeneity. Dispersion within sector and across countries tends to be higher in some services sectors assuming a less tradable nature which suggests that the Single Market integration is partial particularly relaxing the assumption of perfect competition in the labour market. We report also figures for the aggregate economy and show that Eastern countries tend to depict lower product and labour market imperfections compared to other countries in the EU. Also, we provide evidence in favour of a very limited adjustment of both product and labour market imperfections following the international and financial crisis.
Micro-mechanisms Behind Declining Labour Shares: Market Power, Production Processes, and Global Competition
in: IWH-CompNet Discussion Papers, Nr. 3, 2019
This article investigates how changing production processes and increasing market power at the firm level relate to a fall in Germany’s manufacturing sector labour share. Coinciding with the fall of the labour share, I document a rise in firms’ product and labour market power. Notably, labour market power is a more relevant source of firms’ market power than product market power. Increasing product and labour market power, however, only account for 30% of the fall in the labour share. The remaining 70% are explained by a transition of firms towards less labour-intensive production activities. I study the role of final product trade in causing those secular movements. I find that rising foreign export demand contributes to a decline in the labour share by increasing labour market power within firms and by inducing a reallocation of economic activity from nonexporting- high-labour-share to exporting-low-labour-share firms
Labour Market Power and the Distorting Effects of International Trade
in: IWH-CompNet Discussion Papers, Nr. 2, 2019
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 labor market distortions in monetary terms and document large degrees of those distortions in Germany’s manufacturing sector. Import competition can only exert labor 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.
The Effect of the Single Currency on Exports: Comparative Firm-level Evidence
in: IWH-CompNet Discussion Papers, Nr. 1, 2019
We investigate how adopting the euro affects exports using firm-level data from Slovakia and Estonia. In contrast to previous studies, we focus on countries that adopted the euro individually and had different exchange rate regimes prior to doing so. Following the New Trade Theory we consider three types of adjustment: firm selection, changes in product varieties and changes in the average value of the exports that compose the exports of individual firms. The euro effect is identified by a difference in differences analysis comparing exports by firms to the euro area countries with exports to the EU countries that are not members of the euro area. The results highlight the importance of the transaction costs channel related to exchange rate volatility. We find the euro has a strong pro-trade effect in Slovakia, which switched to the euro from a floating exchange rate, while it has almost no effect in Estonia, which had a fixed exchange rate to the euro prior to the euro changeover. Our findings indicate that the euro effect manifested itself mainly through the intensive margin and that the gains from trade were heterogeneous across firm characteristics.
Living with Lower Productivity Growth: Impact on Exports
in: IWH-CompNet Discussion Papers, Nr. 1, 2018
This paper investigates the impact of sustained lower productivity growth on exports, by looking at the role of the productivity distribution and allocative efficiency as drivers of export performance. It follows and goes beyond the work of Barba Navaretti et al. (2017), analysing the effects of productivity on exports depending on the dynamics of allocative efficiency. Low productivity growth is a well-documented stylised fact in Western countries – and possibly a reality likely to persist for some time. What could be the impact of persistent sluggish growth of productivity on exports? To shed light on this question, this paper examines the relationship between the productivity distribution of firms and sectoral export performance. The structure of firms within countries or even sectors matters tremendously for the nexus between productivity and exports at the macroeconomic level, as the theoretical and empirical literature documents. For instance, whether too few firms at the top (lack of innovation) or too many firms at the bottom (weak market selection) drives slow average productivity at the macro level has very different implications and therefore demands different policy responses.
