Central Bank Transparency and the Volatility of Exchange Rates
Stefan Eichler, Helge Littke
Abstract
We analyze the effect of monetary policy transparency on bilateral exchange rate volatility. We test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010. We find strong empirical evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility. Using interaction models, we find that this effect is more pronounced for countries with a lower flexibility of goods prices, a lower level of central bank conservatism, and a higher interest rate sensitivity of money demand.

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,
No. 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.

Macro-Financial Modelling of the Singapore Economy: a GVAR Approach
Alessandro Galesi, Filippo di Mauro
Monetary Authority of Singapore Macroeconomic Review,
October
2017
Abstract
Globalisation has greatly increased the degree of interdependence across countries. Macroeconomic policy must therefore take a global perspective, particularly in the case of small open economies such as Singapore. From a modeller’s point of view, this requires considering many countries, regions and markets, as well as multiple channels of transmission, including trade and financial linkages. Cross-country interdependencies are increasingly reflected in the effects of global shocks, to oil or food prices for example, as well as technology and policy uncertainty spillovers.

Pricing Sin Stocks: Ethical Preference vs. Risk Aversion
Stefano Colonnello, Giuliano Curatola, Alessandro Gioffré
Abstract
We develop a model that reproduces the return and volatility spread between sin and non-sin stocks, where investors trade off dividends with the ethical assessment of companies. We relax the assumption of boycott behaviour and investigate the role played by the dividend share of sin stocks on their return and volatility spread relative to non-sin stocks. We empirically show that the dividend share predicts a positive return and volatility spread. This pattern is reproduced by our model when dividends and ethicalness are complementary goods and investors are sufficiently risk averse.

Criminal Network Formation and Optimal Detection Policy: The Role of Cascade of Detection
Liuchun Deng, Yufeng Sun
Journal of Economic Behavior and Organization,

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.

Reformvorschlag: Renten künftig an Verbraucherpreise koppeln
Bislang orientiert sich die jährliche Anpassung der Renten in Deutschland vor allem an der Entwicklung der Bruttolöhne und -gehälter. Ein Nachhaltigkeitsfaktor in der Rentenanpassungsformel berücksichtigt zudem den demographischen Wandel, dämpft also die Rentenanpassung bei einer Alterung der Bevölkerung – allerdings bislang nicht genug, um trotz eines sinkenden Rentenniveaus einen deutlichen Anstieg der Beiträge in der Zukunft zu verhindern. Zu dem bestehenden System gibt es durchaus Alternativen. So könnte das Rentenniveau bei Renteneintritt auf dem heutigen Niveau oder sogar etwas darüber fixiert werden und dennoch der Beitragsanstieg gedämpft werden, wenn die Renten derjenigen, die bereits in Rente sind, nur noch mit der Inflationsrate steigen. Der Lebensstandard bliebe dadurch erhalten, so lautet ein Vorschlag Oliver Holtemöllers, Leiter der Abteilung Makroökonomie und Vizepräsident am Leibniz-Institut für Wirtschaftsforschung Halle (IWH).

The German economy: Growing strongly
In the summer of 2017, the upswing in Germany continues. „For this year, we forecast gross domestic product to expand by 1.9%, as it did in 2016, and for 2018 by 2.0%” says Oliver Holtemöller, head of the Department Macroeconomics and IWH vice president.

Predicting the Rise of EU Right-Wing Populism in Response to Unbalanced Immigration

2017
Abstract
Among the central tenets of globalization is the free migration of labor. Although much has been written about the benefits of globalization, little is known about its limitations and how antiglobalist sentiment can be strongly affected by high levels of immigration. Analyzing poll data from a group of EU countries affected by the recent migrant crisis, we find that over the last three years the percentage of right-wing (RW) populist voters in a given country depends on the prevalence of immigrants in this country’s population and the total immigration inflow into the entire EU. The latter is likely due to the perception that the EU functions as a supranational state in which a lack of inner borders means that “someone else’s problem” can easily become “my problem.” We find that the increase in the percentage of RW voters substantially surpasses the percentage of immigration inflow, implying that if this process continues, ongoing democratic processes will cause RW populism to prevail and globalization to rapidly decrease. We locate tipping points between the fraction of immigrants and the rise of RW populism, and we model our empirical findings using a complex network framework in which the success of globalization rests on a balance between immigration and immigrant integration.

How Do Political Factors Shape the Bank Risk-Sovereign Risk Nexus in Emerging Markets?
Stefan Eichler
Review of Development Economics,
No. 3,
2017
Abstract
This paper studies the role of political factors for determining the impact of banking sector distress on sovereign bond yield spreads for a sample of 19 emerging market economies in the period 1994–2013. Using interaction models, I find that the adverse impact of banking sector distress on sovereign solvency is less pronounced for countries with a high degree of political stability, a high level of power sharing within the government coalition, a low level of political constraint within the political system, and for countries run by powerful and effective governments. The electoral cycle pronounces the bank risk–sovereign risk transfer.

Abstract
Gegenstand der Untersuchung sind Schlüsselereignisse und politischen Strategien in der Wirtschaftsgeschichte der früheren DDR. Das Growth Accounting Model wird angewandt, um den Einfluss des Inputs von Arbeit und Kapital sowie des technischen Fortschritts auf das Wachstum des Bruttoinlandsprodukts in den verschiedenen Perioden abzuschätzen. Hauptergebnis ist die Erkenntnis, dass nur während der Wirtschaftsreformen in der zweiten Hälfte der Sechziger von der die totale Faktorproduktivität der entscheidende Einfluss auf das Wirtschaftswachstum ausging.
