IWH Discussion Papers,
Nr. 1,
2023
Abstract
Several models posit a positive cross-sectional correlation between markups and firm size, which characterizes misallocation, factor shares, and gains from trade. Accounting for labor market power in markup estimation, we find instead that larger firms have lower product markups but higher wage markdowns. The negative markup-size correlation turns positive when conditioning on markdowns, suggesting interactions between product and labor market power. Our findings are robust to common criticism (e.g., price bias, non-neutral technology) and hold across 19 European countries. We discuss possible mechanisms and resulting implications, highlighting the importance of studying input and output market power in a unified framework.

The Value of Firm Networks: A Natural Experiment on Board Connections
Ester Faia, Maximilian Mayer, Vincenzo Pezone
SAFE Working Papers,
Nr. 269,
2022
Abstract
We present causal evidence on the effect of boardroom networks on firm value and compensation policies. We exploit a ban on interlocking directorates of Italian financial and insurance companies as exogenous variation and show that firms that lose centrality in the network experience negative abnormal returns around the announcement date. The key driver of our results is the role of boardroom connections in reducing asymmetric information. The complementarities with the input-output and cross-ownership networks are consistent with this channel. Using hand-collected data, we also show that network centrality has a positive effect on directors’ compensation, providing evidence of rent sharing.

Understanding Post-Covid Inflation Dynamics
Martín Harding, Jesper Lindé, Mathias Trabandt
Abstract
We propose a macroeconomic model with a nonlinear Phillips curve that has a flat slope when inflationary pressures are subdued and steepens when inflationary pressures are elevated. The nonlinear Phillips curve in our model arises due to a quasi-kinked demand schedule for goods produced by firms. Our model can jointly account for the modest decline in inflation during the Great Recession and the surge in inflation during the Post-Covid period. Because our model implies a stronger transmission of shocks when inflation is high, it generates conditional heteroscedasticity in inflation and inflation risk. Hence, our model can generate more sizeable inflation surges due to cost-push and demand shocks than a standard linearized model. Finally, our model implies that the central bank faces a more severe trade-off between inflation and output stabilization when inflation is high.

Resolving the Missing Deflation Puzzle

Abstract
A resolution of the missing deflation puzzle is proposed. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.

Globalization, Productivity Growth, and Labor Compensation

Nr. 7,
2022
Abstract
We analyze how changes in international trade integration affect productivity and the functional income distribution. To account for endogeneity, we construct a leaveout measure for international trade integration for country-industry pairs using international input-output tables. Our findings corroborate on the country-industry level that international trade integration increases productivity. Moreover, we show that both trade in intermediate inputs and trade in value added is associated with lower labor shares in emerging markets. For advanced countries, we document a positive effect of trade in value added on the labor share of income. Further, we show that the effects on productivity and labor share are heterogeneous across different sectors. Finally, we discuss the implications of our results for a possible throwback in international trade integration due to experiences from recent crises.

International Trade Barriers and Regional Employment: The Case of a No-Deal Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Journal of Economic Structures,
Nr. 11,
2021
Abstract
We use the World Input–Output Database (WIOD) combined with regional sectoral employment data to estimate the potential regional employment effects of international trade barriers. We study the case of a no-deal Brexit in which imports to the United Kingdom (UK) from the European Union (EU) would be subject to tariffs and non-tariff trade costs. First, we derive the decline in UK final goods imports from the EU from industry-specific international trade elasticities, tariffs and non-tariff trade costs. Using input–output analysis, we estimate the potential output and employment effects for 56 industries and 43 countries on the national level. The absolute effects would be largest in big EU countries which have close trade relationships with the UK, such as Germany and France. However, there would also be large countries outside the EU which would be heavily affected via global value chains, such as China, for example. The relative effects (in percent of total employment) would be largest in Ireland followed by Belgium. In a second step, we split up the national effects on the NUTS-2 level for EU member states and additionally on the county (NUTS-3) level for Germany. The share of affected workers varies between 0.03% and 3.4% among European NUTS-2 regions and between 0.15% and 0.4% among German counties. A general result is that indirect effects via global value chains, i.e., trade in intermediate inputs, are more important than direct effects via final demand.

Die veränderten Wettbewerbsbedingungen von Nordrhein-Westfalen durch ein verändertes ‚level-playing-field‘ in den Wirtschaftsbeziehungen zum Vereinigten Königreich und Nordirland

Abstract
Am 31.01.2020 ist das Vereinigte Königreich Großbritannien und Nordirland (Großbritannien) aus der Europäischen Union (EU) ausgetreten. Das Land ist bisher als Handelspartner der nordrhein-westfälischen Wirtschaft von erheblicher Bedeutung gewesen: 2015, im Jahr vor dem britischen Volksentscheid zugunsten eines Austritts, war es mit einem Anteil von 7,7% der drittwichtigste Absatzmarkt für Warenexporte aus Nordrhein-Westfalen, und immerhin 4,6% aller Warenimporte stammten aus Großbritannien. In der vorliegenden Studie werden die Konsequenzen des Brexit für das Land Nordrhein-Westfalen erörtert. Der Fokus liegt dabei auf der kurzen bis mittleren Frist, denn das zentrale Instrument der Analyse, die Input-Output-Rechnung, nutzt Informationen über gegenwärtige Wirtschaftsstrukturen, die sich an die nach dem Austritt Großbritanniens neuen Rahmenbedingungen im Lauf der Zeit anpassen werden. Die Perspektiven für die wirtschaftlichen Beziehungen zwischen Großbritannien und der EU, wie sie sich im Frühjahr 2020 darstellen, werden am Anfang der Studie (Abschnitt 2) skizziert. Daran schließt sich ein Überblick der Literatur zu den wirtschaftlichen Folgen des Brexit für Europa, für Deutschland und für einzelne Regionen an (Abschnitt 3). Das zentrale Kapitel der Studie (Abschnitt 4) beleuchtet die Effekte des Brexit auf die Wirtschaft Nordrhein-Westfalens. Dabei geht es vor allem um den Güterhandel, die Produktion und die Beschäftigung, aber auch um Effekte auf Investitionen und Arbeitsproduktivität. Um auch wichtige indirekte Effekte über Vorleistungsbeziehungen zu erfassen, kommt die Input-Output-Analyse zum Einsatz. Nach einer kurzen Darstellung der Wirtschaftsstruktur Nordrhein-Westfalens und der Handelsverflechtungen zwischen Großbritannien, Deutschland und der EU werden die kurz- bis mittelfristigen Effekte des Brexit auf den Güterhandel, die Produktion und die Beschäftigung in Deutschland und in neun nordrhein-westfälischen Regionen simuliert. An die so erzielten Ergebnisse schließen sich qualitative Überlegungen zu den Effekten auf Investitionstätigkeit und Produktivitätsentwicklung an. In Abschnitt 5 wird diskutiert, ob sich mit dem Brexit nicht auch Chancen für die Wirtschaft Nordrhein-Westfalens bieten. Zu diesem Zweck wird untersucht, in welchen Branchen sowohl Großbritannien als auch Nordrhein-Westfalen bisher innerhalb der EU komparative Vorteile gehabt haben, und ob der Austritt Großbritanniens dort Marktanteilsgewinne der heimischen Wirtschaft ermöglichen könnte. In Abschnitt 6 wird der Frage nachgegangen, welche Instrumente und Maßnahmen von der Politik genutzt werden könnten, um einen fairen und regelbasierten Wettbewerb auf Basis des bisherigen ‚level-playing-field‘ zwischen nordrhein-westfälischen und britischen Unternehmen zu gewährleisten. In einem abschließenden Abschnitt 7 werden die wichtigsten Ergebnisse der Studie zusammengefasst.

Optimizing Policymakers’ Loss Functions in Crisis Prediction: Before, Within or After?
Peter Sarlin, Gregor von Schweinitz
Macroeconomic Dynamics,
Nr. 1,
2021
Abstract
Recurring financial instabilities have led policymakers to rely on early-warning models to signal financial vulnerabilities. These models rely on ex-post optimization of signaling thresholds on crisis probabilities accounting for preferences between forecast errors, but come with the crucial drawback of unstable thresholds in recursive estimations. We propose two alternatives for threshold setting with similar or better out-of-sample performance: (i) including preferences in the estimation itself and (ii) setting thresholds ex-ante according to preferences only. Given probabilistic model output, it is intuitive that a decision rule is independent of the data or model specification, as thresholds on probabilities represent a willingness to issue a false alarm vis-à-vis missing a crisis. We provide real-world and simulation evidence that this simplification results in stable thresholds, while keeping or improving on out-of-sample performance. Our solution is not restricted to binary-choice models, but directly transferable to the signaling approach and all probabilistic early-warning models.

The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession

Macroeconomic Dynamics,
Nr. 6,
2020
Abstract
In this paper, we analyze the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimizing households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical components of output, hours worked and private investment. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, and transfers prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to considering fiscal foresight.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms.
