Skill Mismatch and the Costs of Job Displacement
Frank Neffke, Ljubica Nedelkoska, Simon Wiederhold
Abstract
Establishment closures have lasting negative consequences for the workers they displace from their jobs. We study how these consequences vary with the amount of skill mismatch that workers experience after job displacement. Developing new measures of occupational skill redundancy and skill shortage, we analyze the work histories of individuals in Germany between 1975 and 2010. We estimate differencein- differences models, using a sample of displaced workers who are matched to statistically similar non-displaced workers. We find that displacements increase the probability of occupational change eleven-fold. Moreover, the magnitude of postdisplacement earnings losses strongly depends on the type of skill mismatch that workers experience in such job switches. Whereas skill shortages are associated with relatively quick returns to the counterfactual earnings trajectories that displaced workers would have experienced absent displacement, skill redundancy sets displaced workers on paths with permanently lower earnings. We show that these differences can be attributed to differences in mismatch after displacement, and not to intrinsic differences between workers making different post-displacement career choices.

Identifying Rent-sharing Using Firms‘ Energy Input Mix
Matthias Mertens, Steffen Müller, Georg Neuschäffer
IWH Discussion Papers,
No. 19,
2022
Abstract
We present causal evidence on the rent-sharing elasticity of German manufacturing firms. We develop a new firm-level Bartik instrument for firm rents that combines the firms‘ predetermined energy input mix with national energy carrier price changes. Reduced-form evidence shows that higher energy prices depress wages. Instrumental variable estimation yields a rent-sharing elasticity of approximately 0.20. Rent-sharing induced by energy price variation is asymmetric and driven by energy price increases, implying that workers do not benefit from energy price reductions but are harmed by price increases. The rent-sharing elasticity is substantially larger in small (0.26) than in large (0.17) firms.

Evolvement of China-related Topics in Academic Accounting Research: Machine Learning Evidence
June Cao, Zhanzhong Gu, Iftekhar Hasan
China Accounting and Finance Review,
No. 4,
2020
Abstract
This study employs an unsupervised machine learning approach to explore the evolution of accounting research. We are particularly interested in exploring why international researchers and audiences are interested in China-related issues; what kinds of research topics related to China are mainly investigated in globally recognised journals; and what patterns and emerging topics can be explored by comprehensively analysing a big sample. Using a training sample of 23,220 articles from 46 accounting journals over the period 1980 to 2018, we first identify the optimal number of accounting research topics; the dynamic patterns of these accounting research topics are explored on the basis of 46 accounting journals to show changes in the focus of accounting research. Further, we collect articles related to Chinese accounting research from 18 accounting journals, eight finance journals, and eight management journals over the period 1980 to 2018. We objectively identify China-related accounting research topics and map them to the stages of China’s economic development. We attempt to identify the China-related issues global researchers are interested in and whether accounting research reflects the economic context. We use HistCite TM to generate a citation map along a timeline to illustrate the connections between topics. The citation clusters demonstrate “tribalism” phenomena in accounting research. The topics related to Chinese accounting research conducted by international accounting researchers reveal that accounting changes mirror economic reforms. Our findings indicate that accounting research is embedded in the economic context.

Transactional and Relational Approaches to Political Connections and the Cost of Debt
Taufiq Arifin, Iftekhar Hasan, Rezaul Kabir
Journal of Corporate Finance,
December
2020
Abstract
This paper examines the economic effects of a firm's approach to developing and maintaining political connections. Specifically, we investigate whether lenders favor transactional connection as opposed to relational connection. By tracing firms in a politically volatile emerging democracy in Indonesia, we find that firms following a transactional political connection strategy experience a relatively lower cost of debt than those with a relational strategy. The effect is more pronounced for firms facing high financial distress. The finding is robust to cost of bank loans and a variety of regression methods. Overall, the evidence suggests that in times of frequently changing political regimes, firms benefit from a transactional relationship with politicians as it enables to update connection with the government in power. Relational connection is valuable for a firm only when the political regime connected with it gains power.

Ostdeutschland - Eine Bilanz
Einzelveröffentlichungen,
Festschrift für Gerhard Heimpold, IWH
2020
Abstract
Anlass dieser Festschrift ist die Verabschiedung von Dr. Gerhard Heimpold, dem stellvertretenden Leiter der Abteilung Strukturwandel und Produktivität am Leibniz-Institut für Wirtschaftsforschung Halle (IWH), aus dem aktiven Berufsleben in den wohlverdienten Ruhestand. Gerhard Heimpold forschte am IWH zu Aspekten der Regionalentwicklung Ostdeutschlands unter Beachtung des politischen und wirtschaftlichen Transformationsprozesses. Er gehört heute zu den wenigen Experten in Deutschland, die umfassende ökonomische Kenntnis über den gesamten Verlauf des Transformationsprozesses der ostdeutschen Wirtschaft seit Mitte der 1980er Jahre vorweisen können. Gerhard Heimpold hat im Laufe seiner akademischen Ausbildung und seiner ersten wissenschaftlichen Tätigkeit tiefe Einblicke in die Ausgestaltung und Funktionsweise der sozialistischen Planwirtschaft der DDR erhalten und konnte dieses Wissen nach dem Mauerfall 1989 in wichtige wissenschaftliche Beiträge auf dem Gebiet der internationalen Transformationsforschung einbringen.

Managerial Effect or Firm Effect: Evidence from the Private Debt Market
Bill Francis, Iftekhar Hasan, Yun Zhu
Financial Review,
No. 1,
2020
Abstract
This paper provides evidence that the managerial effect is a key determinant of firms’ cost of capital, in the context of private debt contracting. Applying the novel empirical method developed by an earlier study to a large sample that tracks the job movement of top managers, we find that the managerial effect is a critical and significant factor that explains a large part of the variation in loan contract terms more accurately than firm fixed effects. Additional evidence shows that banks “follow” managers when they change jobs and offer loan contracts with preferential terms to their new firms.

Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis
Jutta Günther, Maria Kristalova, Udo Ludwig
Journal of Evolutionary Economics,
No. 5,
2019
Abstract
When an external shock such as the economic crisis in 2008/2009 occurs, the interconnectedness of sectors can be affected. This paper investigates whether the R&D sector experienced changes in its sectoral integration through the recession. Based on an input-output analysis, it can be shown that the linkages of the R&D sector with other sectors remain stable. In some countries, the inter-sectoral integration becomes even stronger. Policy makers can be encouraged to use public R&D spending as a means of fiscal policy against an economic crisis.
