United Country – Three Decades After the Wall Came Down
Einzelveröffentlichungen,
2019
Abstract
Die Berliner Mauer als das Symbol der deutschen Teilung ist mittlerweile länger verschwunden als sie gestanden hat, doch die Unterschiede innerhalb des Landes sind auch nach drei Jahrzehnten noch sichtbar. Jüngste Forschungsergebnisse zeigen jedoch, dass die Bruchkante der wirtschaftlichen Entwicklung nicht immer ausschließlich entlang der ehemaligen innerdeutschen Grenze verläuft, sondern neben dem West-Ost-Gefälle auch Süd-Nord- oder Stadt-Land-Unterschiede zutage treten.

How Do Banks React to Catastrophic Events? Evidence from Hurricane Katrina
Claudia Lambert, Felix Noth, Ulrich Schüwer
Review of Finance,
No. 1,
2019
Abstract
This paper explores how banks react to an exogenous shock caused by Hurricane Katrina in 2005, and how the structure of the banking system affects economic development following the shock. Independent banks based in the disaster areas increase their risk-based capital ratios after the hurricane, while those that are part of a bank holding company on average do not. The effect on independent banks mainly comes from the subgroup of highly capitalized banks. These independent and highly capitalized banks increase their holdings in government securities and reduce their total loan exposures to non-financial firms, while also increasing new lending to these firms. With regard to local economic development, affected counties with a relatively large share of independent banks and relatively high average bank capital ratios show higher economic growth than other affected counties following the catastrophic event.

Inference in Structural Vector Autoregressions when the Identifying Assumptions are not Fully Believed: Re-evaluating the Role of Monetary Policy in Economic Fluctuations
Christiane Baumeister, James D. Hamilton
Journal of Monetary Economics,
2018
Abstract
Point estimates and error bands for SVARs that are set identified are only justified if the researcher is persuaded that some parameter values are a priori more plausible than others. When such prior information exists, traditional approaches can be generalized to allow for doubts about the identifying assumptions. We use information about both structural coefficients and impacts of shocks and propose a new asymmetric t-distribution for incorporating information about signs in a nondogmatic way. We apply these methods to a three-variable macroeconomic model and conclude that monetary policy shocks are not the major driver of output, inflation, or interest rates.

Within Gain, Structural Pain: Capital Account Liberalization and Economic Growth
Xiang Li, Dan Su
New Structural Economics Working Paper No. E2018010,
2018
Abstract
This paper is the first to study the effects of capital account liberalization on structural transformation and compare the contribution of within term and structural term to economic growth. We use a 10-sector-level productivity dataset to decomposes the effects of opening capital account on within-sector productivity growth and cross-sector structural transformation. We find that opening capital account is associated with labor productivity and employment share increment in sectors with higher human capital intensity and external financial dependence, as well as non-tradable sectors. But it results in a growth-reducing structural transformation by directing labor into sectors with lower productivity. Moreover, in the ten years after capital account liberalization, the contribution share of structural transformation decreases while that of within productivity growth increases. We conclude that the relationship between capital account liberalization and economic growth is within gain and structural pain.

Urban Occupational Structures as Information Networks: The Effect on Network Density of Increasing Number of Occupations

Abstract
Urban economies are composed of diverse activities, embodied in labor occupations, which depend on one another to produce goods and services. Yet little is known about how the nature and intensity of these interdependences change as cities increase in population size and economic complexity. Understanding the relationship between occupational interdependencies and the number of occupations defining an urban economy is relevant because interdependence within a networked system has implications for system resilience and for how easily can the structure of the network be modified. Here, we represent the interdependencies among occupations in a city as a non-spatial information network, where the strengths of interdependence between pairs of occupations determine the strengths of the links in the network. Using those quantified link strengths we calculate a single metric of interdependence–or connectedness–which is equivalent to the density of a city’s weighted occupational network. We then examine urban systems in six industrialized countries, analyzing how the density of urban occupational networks changes with network size, measured as the number of unique occupations present in an urban workforce. We find that in all six countries, density, or economic interdependence, increases superlinearly with the number of distinct occupations. Because connections among occupations represent flows of information, we provide evidence that connectivity scales superlinearly with network size in information networks.

Public Investment Subsidies and Firm Performance – Evidence from Germany
Matthias Brachert, Eva Dettmann, Mirko Titze
Jahrbücher für Nationalökonomie und Statistik,
No. 2,
2018
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.

What is holding back the banking union?
The European Commission wants to better regulate and monitor the European banking sector. In many EU Member States, however, the necessary directives are being implemented extremely slowly. Surprisingly, the reasons for this do not lie in politics and banking structures, but in the institutional framework conditions and existing regulations in the Member States, as argued by Michael Koetter, Thomas Krause and Lena Tonzer from the Halle Institute for Economic Research (IWH).

Non-linearity in the Finance-Growth Nexus: Evidence from Indonesia
Nuruzzaman Arsyad, Iftekhar Hasan, Wahyoe Soedarmono
International Economics,
August
2017
Abstract
This paper investigates the finance-growth nexus where bank credit is decomposed into investment, consumption, and working capital credit. From a panel dataset of provinces in Indonesia, it documents that higher financial development measured by financial deepening and financial intermediation exhibits an inverted U-shaped relationship with economic growth. This non-linear effect of financial deepening is driven by both investment credit and consumption credit. These results suggest that too much investment credit and, to a lesser extent, consumption credit are detrimental to economic growth. Ultimately, only financial intermediation associated with working capital credit has a positive and monotonic impact on economic growth.

Abstract
The Halle Institute for Economic Research (IWH) was founded in 1992 and operates three research departments: Macroeconomics, Financial Markets, and Structural Change and Productivity. The IWH’s research structure is designed to foster close interplay between micro and macroeconomic research, however it has its roots in the empirical research conducted on the transition from a planned to a market economy, with a particular focus on East Germany.
