Economic Growth: The Past, the Present, and the Future

Ufuk Akcigit
Journal of Political Economy, Nr. 6, 2017
Abstract
“Is there some action a government of India could take that would lead the Indian economy to grow like Indonesia’s or Egypt’s? If so, what, exactly? If not, what is it about the ‘nature of India’ that makes it so? The consequences for human welfare involved in questions like these are simply staggering: Once one starts to think about them, it is hard to think about anything else. (Lucas 1988, 5)” These words by the Nobel laureate Chicago economist Robert Lucas Jr. summarize why so many great scholars found it hard to “think about anything else” and spent their careers trying to understand the process of economic growth. Economies are complex systems resulting from the actions of many actors. This complexity makes it challenging, but also infinitely interesting, to understand the determinants of economic growth. What are the roles of human capital, fertility, ideas, basic science, and public policy for growth? These are just some of the important questions that were posed by many highly influential studies featured in the issues of the Journal of Political Economy over the years. Indeed, this journal has been the platform to diffuse many of the brilliant ideas and start important debates in the field of economic growth. In this short paper, my goal is to revisit some of those seminal papers, briefly describe some of the more recent contributions, and end with some thoughts about the future direction of the field. The reader should note in advance that the list of work covered here is by no means exhaustive and mostly targets work that has been featured in issues of the JPE.

R&D Collaborations and the Role of Proximity

Philipp Marek, Mirko Titze, Clemens Fuhrmeister, Ulrich Blum
Regional Studies, Nr. 12, 2017
Abstract
R&D collaborations and the role of proximity. Regional Studies. This paper explores the impact of proximity measures on knowledge exchange measured by granted research and development (R&D) collaboration projects in German NUTS-3 regions. The results are obtained from a spatial interaction model including eigenvector spatial filters. Not only geographical but also other forms of proximity (technological, organizational and institutional) have a significant influence on the emergence of collaborations. Furthermore, the results suggest interdependences between proximity measures. Nevertheless, the analysis does not show that other forms of proximity may compensate for missing geographical proximity. The results indicate that (subsidized) collaborative innovation activities tend to cluster.

Coming to Work While Sick: An Economic Theory of Presenteeism With an Application to German Data

Boris Hirsch, Daniel S. J. Lechmann, Claus Schnabel
Oxford Economic Papers, Nr. 4, 2017
Abstract
Presenteeism, i.e. attending work while sick, is widespread and associated with significant costs. Still, economic analyses of this phenomenon are rare. In a theoretical model, we show that presenteeism arises due to differences between workers in (healthrelated) disutility from workplace attendance. As these differences are unobservable by employers, they set wages that incentivise sick workers to attend work. Using a large representative German data set, we test several hypotheses derived from our model. In line with our predictions, we find that bad health status and stressful working conditions are positively related to presenteeism. Better dismissal protection, captured by higher tenure, is associated with slightly fewer presenteeism days, whereas the role of productivity and skills is inconclusive.

Betriebsräte und andere Formen der betrieblichen Mitarbeitervertretung – Substitute oder Komplemente?

Stefan Ertelt, Boris Hirsch, Claus Schnabel
Industrielle Beziehungen, Nr. 3, 2017
Abstract
Der Beitrag untersucht anhand des IAB-Betriebspanels (2004-2013) die Verbreitung, Entwicklung und Interdependenz von Betriebsräten und anderen, meist betriebsinitiierten Formen der Mitarbeitervertretung (wie z.B. Runde Tische). In der Privatwirtschaft sind Betriebsräte gleich häufig zu finden wie andere Mitarbeitervertretungen, doch kommt eine gleichzeitige Existenz beider Gremien in einem Betrieb kaum vor. Ökonometrische Analysen mit rekursiven Probit-Modellen verdeutlichen, dass z.T. unterschiedliche Faktoren das Vorhandensein dieser alternativen Formen der Mitarbeitervertretung erklären und dass bezüglich ihrer Existenz, Gründung und Auflösung Betriebsräte und andere Mitarbeitervertretungen negativ miteinander korrelieren. Dies deutet darauf hin, dass zwischen beiden Formen der Arbeitnehmerpartizipation eine überwiegend substitutive Beziehung besteht.

Criminal Network Formation and Optimal Detection Policy: The Role of Cascade of Detection

Liuchun Deng, Yufeng Sun
Journal of Economic Behavior & Organization, September 2017
Abstract
This paper investigates the effect of cascade of detection, how detection of a criminal triggers detection of his network neighbors, on criminal network formation. We develop a model in which criminals choose both links and actions. We show that the degree of cascade of detection plays an important role in shaping equilibrium criminal networks. Surprisingly, greater cascade of detection could reduce ex ante social welfare. In particular, we prove that full cascade of detection yields a weakly denser criminal network than that under partial cascade of detection. We further characterize the optimal allocation of the detection resource and demonstrate that it should be highly asymmetric among ex ante identical agents.

Benchmark Value-added Chains and Regional Clusters in R&D-intensive Industries

Reinhold Kosfeld, Mirko Titze
International Regional Science Review, Nr. 5, 2017
Abstract
Although the phase of euphoria seems to be over, policy makers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and related fields. Although there has been some progress in locating clusters, in most cases only limited knowledge on the geographical extent of regional clusters has been established. In the present article, we present a hybrid approach to cluster identification. Dominant buyer–supplier relationships are derived by qualitative input–output analysis from national input–output tables, and potential regional clusters are identified by spatial scanning. This procedure is employed to identify clusters of German research and development-intensive industries. A sensitivity analysis reveals good robustness properties of the hybrid approach with respect to variations in the quantitative cluster composition.

Gender Quotas and Human Capital Formation: A Relative Deprivation Approach

Walter Hyll
German Economic Review, Nr. 3, 2017
Abstract
We study a quota's effect on individual human capital investment incentives beyond merely altering individual's overall probability of being promoted. We assume that individuals sense relative deprivation from unfavorable (income) comparisons within their reference group and that comparisons take place within the same gender. The introduction of a female quota increases (decreases) the number of women (men) holding top positions. On one hand, the relative deprivation to which female individuals are subjected to increases. These female individuals respond to an increase in their relative deprivation by acquiring additional human capital which, because it enables them to increase their earnings, reduces their relative deprivation. On the other hand, male individuals invest less in human capital in response to a decrease in relative deprivation. We show that the human capital formed by women who are encouraged to do so by the quotas is larger than the human capital that men who are discouraged by the quotas refrain from forming. However, the positive human capital accumulation effect hinges on a certain level of ability by gender and on how much individuals perceive relative deprivation.

Imputation Rules for the Implementation of the Pre-unification Education Variable in the BASiD Data Set

André Diegmann
Journal for Labour Market Research, 2017
Abstract
Using combined data from the German Pension Insurance and the Federal Employment Agency (BASiD), this study proposes different procedures for imputing the pre-unification education variable in the BASiD data. To do so, we exploit information on education-related periods that are creditable for the Pension Insurance. Combining these periods with information on the educational system in the former GDR, we propose three different imputation procedures, which we validate using external GDR census data for selected age groups. A common result from all procedures is that they tend to underpredict (overpredict) the share of high-skilled (low-skilled) for the oldest age groups. Comparing our imputed education variable with information on educational attainment from the Integrated Employment Biographies (IEB) reveals that the best match is obtained for the vocational training degree. Although regressions show that misclassification with respect to IEB information is clearly related to observables, we do not find any systematic pattern across skill groups.

When the Meaning of Work Has Disappeared: Experimental Evidence on Employees’ Performance and Emotions

Adrian Chadi, Sabrina Jeworrek, Vanessa Mertins
Management Science, Nr. 6, 2017
Abstract
This experiment tests for a causal relationship between the meaning of work and employees’ motivation to perform well. The study builds on an existing employer–employee relationship, adding realism to the ongoing research of task meaning. Owing to an unexpected project cancelation, we are able to study how varying the information provided about the meaning of previously conducted work — without the use of deception, but still maintaining a high level of control — affects subsequent performance. We observe a strong decline in exerted effort when we inform workers about the meaninglessness of a job already done. Our data also suggests that providing a supplemental alternative meaning perfectly compensates for this negative performance effect. Individual characteristics such as reciprocal inclinations and trust prompt different reactions. The data also show that the meaning of work affects workers’ emotions, but we cannot establish a clear relationship between emotional responses and performance.

The Dynamic Effects of Works Councils on Labour Productivity: First Evidence from Panel Data

Steffen Müller, Jens Stegmaier
British Journal of Industrial Relations, Nr. 2, 2017
Abstract
We estimate dynamic effects of works councils on labour productivity using newly available information from West German establishment panel data. Conditioning on plant fixed effects and control variables, we find negative productivity effects during the first five years after council introduction but a steady and substantial increase in the councils’ productivity effect thereafter. Our findings support a causal interpretation for the positive correlation between council existence and plant productivity that has been frequently reported in previous studies.
