Kommentar: IWH-Präsident Reint E. Gropp: Die EZB widersteht der Kritik und hält am Anleihekaufprogramm fest; behält sich sogar offen, es auszuweiten. Diese Entscheidung ist vollkommen angemessen.
Die Europäische Zentralbank (EZB) hält an ihrer bisherigen Strategie fest. Darunter fällt auch das vielkritisierte Anleihekaufprogramm, das zunächst bis März 2017 laufen soll. Die EZB hielt sich heute offen, das Programm über den März hinaus weiter zu verlängern und widerstand damit der lauten Kritik, die unter anderem aus den europäischen Großbanken zu hören war.

Monetary-fiscal Policy Interaction and Fiscal Inflation: A Tale of Three Countries
Martin Kliem, Alexander Kriwoluzky, Samad Sarferaz
European Economic Review,
2016
Abstract
We study the impact of the interaction between fiscal and monetary policy on the low-frequency relationship between the fiscal stance and inflation using cross-country data from 1965 to 1999. In a first step, we contrast the monetary–fiscal narrative for Germany, the U.S., and Italy with evidence obtained from simple regression models and a time-varying VAR. We find that the low-frequency relationship between the fiscal stance and inflation is low during periods of an independent central bank and responsible fiscal policy and more pronounced in times of non-responsible fiscal policy and accommodative monetary authorities. In a second step, we use an estimated DSGE model to interpret the low-frequency measure structurally and to illustrate the mechanisms through which fiscal actions affect inflation in the long run. The findings from the DSGE model suggest that switches in the monetary–fiscal policy interaction and accompanying variations in the propagation of structural shocks can well account for changes in the low-frequency relationship between the fiscal stance and inflation.

Wirtschaft im Wandel,
Nr. 2,
2016
Abstract
Der Euroraum verharrt in einer tiefen, vierfachen Krise. Die erste ist eine Wachstumskrise. Im Euroraum liegt die wirtschaftliche Leistung immer noch unterhalb des Niveaus von vor der Finanzkrise 2008. Zudem leidet der Euroraum weiterhin unter hoher Arbeitslosigkeit und zu niedriger Inflation. Der Euroraum leidet außerdem unter einem zu geringen Produktivitätswachstum, vor allem bei den Dienstleistungen. Es fehlt hier an Innovationsdynamik und Investitionen.

On the Low-frequency Relationship Between Public Deficits and Inflation
Martin Kliem, Alexander Kriwoluzky, Samad Sarferaz
Journal of Applied Econometrics,
Nr. 3,
2016
Abstract
We estimate the low-frequency relationship between fiscal deficits and inflation and pay special attention to its potential time variation by estimating a time-varying vector autoregression model for US data from 1900 to 2011. We find the strongest relationship neither in times of crisis nor in times of high public deficits, but from the mid 1960s up to 1980. Employing a structural decomposition of the low-frequency relationship and further narrative evidence, we interpret our results such that the low-frequency relationship between fiscal deficits and inflation is strongly related to the conduct of monetary policy and its interaction with fiscal policy after World War II.

Konjunktur aktuell: Stabile Konjunktur in Deutschland trotz krisenhaften Umfelds
Die deutsche Konjunktur ist trotz internationaler Risiken und politischer Verwerfungen kraftvoll in das Jahr 2016 gestartet. Beschäftigung und Einkommen nehmen zu, und die Binnennachfrage steigt deutlich, auch weil der Staat zusätzliche Ausgaben im Zusammenhang mit der Flüchtlingsmigration tätigt. Allerdings dürfte es nach Einschätzung des IWH im Frühjahr zu einer vorübergehenden Verlangsamung der Dynamik kommen, darauf deuten Stimmungsindikatoren hin. Mit Fortschritten bei der Bewältigung der aktuellen politischen Probleme in Europa dürfte die Zuversicht wieder zunehmen und die deutsche Konjunktur insgesamt stabil bleiben, sodass das Bruttoinlandsprodukt im Jahr 2016 wohl mit einer Rate von 1,5% expandieren wird.

A Market-based Indicator of Currency Risk: Evidence from American Depositary Receipts
Stefan Eichler, Ingmar Roevekamp
IWH Discussion Papers,
Nr. 4,
2016
Abstract
We introduce a novel currency risk measure based on American Depositary Receipts(ADRs). Using a multifactor pricing model, we exploit ADR investors’ exposure to potential devaluation losses to derive an indicator of currency risk. Using weekly data for a sample of 831 ADRs located in 23 emerging markets over the 1994-2014 period, we find that a deterioration in the fiscal and current account balance, as well as higher inflation, increases currency risk. Interaction models reveal that these macroeconomic fundamentals drive currency risk, particularly in countries with managed exchange rates, low levels of foreign exchange reserves and a poor sovereign credit rating.

The Diablo 3 Economy: An Agent Based Approach
Makram El-Shagi, Gregor von Schweinitz
Computational Economics,
Nr. 2,
2016
Abstract
Designers of MMOs such as Diablo 3 face economic problems much like policy makers in the real world, e.g. inflation and distributional issues. Solving economic problems through regular updates (patches) became as important to those games as traditional gameplay issues. In this paper we provide an agent framework inspired by the economic features of Diablo 3 and analyze the effect of monetary policy in the game. Our model reproduces a number of features known from the Diablo 3 economy such as a heterogeneous price development, driven almost exclusively by goods of high quality, a highly unequal wealth distribution and strongly decreasing economic mobility. The basic framework presented in this paper is meant as a stepping stone to further research, where our evidence is used to deepen our understanding of the real-world counterparts of such problems. The advantage of our model is that it combines simplicity that is inherent to model economies with a similarly simple observable counterpart (namely the game environment where real agents interact). By matching the dynamics of the game economy we can thus easily verify that our behavioral assumptions are good approximations to reality.
