Pricing Sin Stocks: Ethical Preference vs. Risk Aversion
Stefano Colonnello, Giuliano Curatola, Alessandro Gioffré
European Economic Review,
2019
Abstract
We develop an ethical preference-based model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading off dividends against ethicalness. When dividends and ethicalness are complementary goods and investors are sufficiently risk averse, the model predicts that the dividend share of sin companies exhibits a positive relation with the future return and volatility spreads. An empirical analysis supports the model’s predictions. Taken together, our results point to the importance of ethical preferences for investors’ portfolio choices and asset prices.

History, Microdata, and Endogenous Growth
Ufuk Akcigit, Tom Nicholas
Annual Review of Economics,
2019
Abstract
The study of economic growth is concerned with long-run changes, and therefore, historical data should be especially influential in informing the development of new theories. In this review, we draw on the recent literature to highlight areas in which study of history has played a particularly prominent role in improving our understanding of growth dynamics. Research at the intersection of historical data, theory, and empirics has the potential to reframe how we think about economic growth in much the same way that historical perspectives helped to shape the first generation of endogenous growth theories.

East Germany Three Decades After the Wall Came Down: What has Been Achieved and What Should Economic Policy Do?
Reint E. Gropp, Gerhard Heimpold
Wirtschaftsdienst,
No. 7,
2019
Abstract
The persistent difference in productivity between East and West Germany not only results from the relative absence of large firms based in the East as many believe. Companies of all sizes exhibit an East-West productivity gap. The gap is larger in urban regions. Scarcity of skilled labour has emerged as the new barrier to business development. In order to boost productivity, economic policy should avoid additional subsidies that are conditional on creating jobs. Additionally, the potential of East German urban areas should be better explored. Mitigating the shortage in qualified workers requires in-migration of skilled labour from abroad, supported by an open mindset and environment.

Study: How financial crises lower life satisfaction and how to prevent this
Financial crises not only result in severe disruptions to the economic system, they also affect people’s life satisfaction. A new study by Martin Luther University Halle-Wittenberg (MLU) and the Halle Institute for Economic Research (IWH) shows that weaker members of society are more affected by increased uncertainty during crisis times, even if they may not be speculating on the stock market themselves. This could potentially also lower their propensity to consume, thereby intensifying the impact of a financial crisis. The study was recently published in “The B.E. Journal of Economic Analysis & Policy”.

Weak foreign demand – economic downturn in Germany

According to IWH summer economic forecast, gross domestic product is expected to increase by only 0.5% in 2019; the forecast for East Germany is 0.8%. The German labour market remains largely robust despite the economic downturn.

Stellungnahme zum „Strukturstärkungsgesetz Kohleregionen“ anlässlich der Anhörung im Ausschuss für Wirtschaft und Energie des Deutschen Bundestages am 15. Mai 2019

Abstract
Die Bundesregierung plant, bis zum Jahr 2038 die Produktion von Strom aus Braunkohle zu beenden. Den von dem Braunkohleausstieg besonders betroffenen Regionen will die Bundesregierung finanzielle Hilfe für den Strukturwandel gewähren. Dazu soll das „Strukturstärkungsgesetz Kohleregionen“ beschlossen werden. In dieser Stellungnahme werden ökonomische Aspekte des vorgesehenen beschleunigten Braunkohleausstiegs diskutiert. Zentrale Aussagen der Stellungnahme sind, dass ein beschleunigter Braunkohleausstieg zwar geeignet ist, nationale Emissionsziele zu erreichen, aber die europäischen bzw. globalen Treibhausgasemissionen dadurch kaum beeinflusst werden. Die gesamtwirtschaftlichen Kosten eines beschleunigten Braunkohleausstiegs dürften überschaubar sein, aber die wirtschaftliche Entwicklung in einzelnen Regionen würde aufgrund der regionalen Konzentration des Braunkohleabbaus deutlich beeinträchtigt werden. Maßnahmen zur Förderung des Strukturwandels in den betroffenen Regionen sollten an den wichtigsten langfristigenWachstumstreibern Bildung sowie Forschung und Entwicklung ansetzen und vor allem das Humankapital stärken. Eine Konzentration auf die Förderung von Sachinvestitionen, auf die Industrie oder auf bestimmte Technologien ist hingegen nicht aussichtsreich in Bezug auf langfristige ökonomische Ziele.

Bank profitability increases after eliminating consolidation barriers
When two banks merge because political consolidation barriers are abolished, the combined entity is considerably more profitable and useful to the real economy. This is the headline result of an analysis of compulsory savings banks mergers carried out by the Halle Institute for Economic Research (IWH). The study yields important insights for the German and the European banking market.
