Abstract
The German government provides discretionary investment grants to structurally weak regions in order to reduce regional inequality. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of regional actors to receive investment grants to identify the causal effects of the policy. We find positive effects of the programme on district-level gross value-added and productivity growth, but no effects on employment and gross wage growth.

Import Competition and Firm Productivity: Evidence from German Manufacturing
Richard Bräuer, Matthias Mertens, Viktor Slavtchev
Abstract
This study analyses empirically the effects of import competition on firm productivity (TFPQ) using administrative firm-level panel data from German manufacturing. We find that only import competition from high-income countries is associated with positive incentives for firms to invest in productivity improvement, whereas import competition from middle- and low-income countries is not. To rationalise these findings, we further look at the characteristics of imports from the two types of countries and the effects on R&D, employment and sales. We provide evidence that imports from high-income countries are relatively capital-intensive and technologically more sophisticated goods, at which German firms tend to be relatively good. Costly investment in productivity appears feasible reaction to such type of competition and we find no evidence for downscaling. Imports from middle- and low-wage countries are relatively labour-intensive and technologically less sophisticated goods, at which German firms tend to generally be at disadvantage. In this case, there are no incentives to invest in innovation and productivity and firms tend to decline in sales and employment.

flexpaneldid: A Stata Command for Causal Analysis with Varying Treatment Time and Duration
Eva Dettmann, Alexander Giebler, Antje Weyh
Abstract
>>A completely revised version of this paper has been published as: Dettmann, Eva; Giebler, Alexander; Weyh, Antje: flexpaneldid. A Stata Toolbox for Causal Analysis with Varying Treatment Time and Duration. IWH Discussion Paper 3/2020. Halle (Saale) 2020.<<
The paper presents a modification of the matching and difference-in-differences approach of Heckman et al. (1998) and its Stata implementation, the command flexpaneldid. The approach is particularly useful for causal analysis of treatments with varying start dates and varying treatment durations (like investment grants or other subsidy schemes). Introducing more flexibility enables the user to consider individual treatment and outcome periods for the treated observations. The flexpaneldid command for panel data implements the developed flexible difference-in-differences approach and commonly used alternatives like CEM Matching and difference-in-differences models. The novelty of this tool is an extensive data preprocessing to include time information into the matching approach and the treatment effect estimation. The core of the paper gives two comprehensive examples to explain the use of flexpaneldid and its options on the basis of a publicly accessible data set.

Public Investment Subsidies and Firm Performance – Evidence from Germany

Jahrbücher für Nationalökonomie und Statistik,
No. 2,

Abstract
This paper assesses firm-level effects of the single largest investment subsidy programme in Germany. The analysis considers grants allocated to firms in East German regions over the period 2007 to 2013 under the regional policy scheme Joint Task ‘Improving Regional Economic Structures’ (GRW). We apply a coarsened exact matching (CEM) in combination with a fixed effects difference-in-differences (FEDiD) estimator to identify the effects of programme participation on the treated firms. For the assessment, we use administrative data from the Federal Statistical Office and the Offices of the Länder to demonstrate that this administrative database offers a huge potential for evidence-based policy advice. The results suggest that investment subsidies have a positive impact on different dimensions of firm development, but do not affect overall firm competitiveness. We find positive short- and medium-run effects on firm employment. The effects on firm turnover remain significant and positive only in the medium-run. Gross fixed capital formation responses positively to GRW funding only during the mean implementation period of the projects but becomes insignificant afterwards. Finally, the effect of GRW-funding on labour productivity remains insignificant throughout the whole period of analysis.

Who Benefits from GRW? Heterogeneous Employment Effects of Investment Subsidies in Saxony Anhalt

IWH Discussion Papers,
No. 27,
2017
Abstract
The paper estimates the plant level employment effects of investment subsidies in one of the most strongly subsidized German Federal States. We analyze the treated plants as a whole, as well as the influence of heterogeneity in plant characteristics and the economic environment. Modifying the standard matching and difference-in-difference approach, we develop a new procedure that is particularly useful for the evaluation of funding programs with individual treatment phases within the funding period. Our data base combines treatment, employment and regional information from different sources. So, we can relate the absolute effects to the amount of the subsidy paid. The results suggest that investment subsidies have a positive influence on the employment development in absolute and standardized figures – with considerable effect heterogeneity.

Wage Bargaining Regimes and Firms‘ Adjustments to the Great Recession
Filippo di Mauro, Maddalena Ronchi
IWH-CompNet Discussion Papers,
No. 1,
2017
Abstract
The paper aims at investigating to what extent wage negotiation set-ups have shaped up firms’ response to the Great Recession, taking a firm-level cross-country perspective. We contribute to the literature by building a new micro-distributed database which merges data related to wage bargaining institutions (Wage Dynamic Network, WDN) with data on firm productivity and other relevant firm characteristics (CompNet). We use the database to study how firms reacted to the Great Recession in terms of variation in profits, wages, and employment. The paper shows that, in line with the theoretical predictions, centralized bargaining systems – as opposed to decentralized/firm level based ones – were accompanied by stronger downward wage rigidity, as well as cuts in employment and profits.

Declining Dynamism, Allocative Efficiency, and the Productivity Slowdown

American Economic Review: Papers and Proceedings,
No. 5,
2017
Abstract
A large literature documents declining measures of business dynamism including high-growth young firm activity and job reallocation. A distinct literature describes a slowdown in the pace of aggregate labor productivity growth. We relate these patterns by studying changes in productivity growth from the late 1990s to the mid 2000s using firm-level data. We find that diminished allocative efficiency gains can account for the productivity slowdown in a manner that interacts with the within-firm productivity growth distribution. The evidence suggests that the decline in dynamism is reason for concern and sheds light on debates about the causes of slowing productivity growth.

Social Comparisons and Attitudes towards Foreigners. Evidence from the ‘Fall of the Iron Curtain’
Walter Hyll, Lutz Schneider
IWH Discussion Papers,
No. 12,
2016
Abstract
We exploit the natural experiment of German re-unification to address the question whether distress from social (income) comparisons results in negative attitudes towards foreigners. Our empirical approach rests upon East German individuals who have West German peers. We use the exogenous variation of wealth of West German peers shortly after the fall of the Berlin Wall as an instrument to identify the effect of distress from social comparisons on East Germans’ attitudes. We find robust evidence that East Germans expose strong negative attitudes towards foreigners, particularly from low-wage countries, if they worry about their economic status compared to better-off peers.

Wirtschaft im Wandel,
No. 5,
2015
Abstract
In Deutschland besteht ein enormer Bedarf an evidenzbasierter Politikberatung. Viele wirtschaftspolitische Interventionen werden bislang nicht umfassend evaluiert, und falls doch, wenden die wenigsten Untersuchungen geeignete Verfahren der Kausalanalyse an, um einen ursächlichen Zusammenhang zwischen der Intervention und dem Erreichen von wirtschaftspolitischen Zielen zu identifizieren. Das Leibniz-Institut für Wirtschaftsforschung Halle hat für diese Aufgabe das Zentrum für evidenzbasierte Politikberatung (IWH-CEP) eingerichtet. Eine Pilotstudie zu den Wirkungen der betrieblichen Investitionsförderung ist bereits angelaufen.
