Did the Swiss Exchange Rate Shock Shock the Market?

Manuel Buchholz Gregor von Schweinitz Lena Tonzer

in: IWH-Diskussionspapiere, Nr. 9, 2018

Abstract

The Swiss National Bank abolished the exchange rate floor versus the Euro in January 2015. Based on a synthetic matching framework, we analyse the impact of this unexpected (and therefore exogenous) shock on the stock market. The results reveal a significant level shift (decline) in asset prices in Switzerland following the discontinuation of the minimum exchange rate. While adjustments in stock market returns were most pronounced directly after the news announcement, the variance was elevated for some weeks, indicating signs of increased uncertainty and potentially negative consequences for the real economy.

On the Empirics of Reserve Requirements and Economic Growth

Jesus Crespo Cuaresma Gregor von Schweinitz Katharina Wendt

in: IWH-Diskussionspapiere, Nr. 8, 2018

Abstract

Reserve requirements, as a tool of macroprudential policy, have been increasingly employed since the outbreak of the great financial crisis. We conduct an analysis of the effect of reserve requirements in tranquil and crisis times on credit and GDP growth making use of Bayesian model averaging methods. In terms of credit growth, we can show that initial negative effects of higher reserve requirements (which are often reported in the literature) tend to be short-lived and turn positive in the longer run. In terms of GDP per capita growth, we find on average a negative but not robust effect of regulation in tranquil times, which is only partly offset by a positive but also not robust effect in crisis times.

7. IWH/INFER-Workshop on Applied Economics and Economic Policy: “Challenges and Implications of Inflationary Dynamics“

Birgit Schultz Gregor von Schweinitz

in: Wirtschaft im Wandel, Nr. 4, 2017

Abstract

Am 7. und 8. September 2017 fand am IWH in Zusammenarbeit mit dem International Network for Economic Research (INFER) und unter Förderung der Stadt Halle (Saale) der 7. Workshop in der Reihe „Applied Economics and Economic Policy“ statt. Im Rahmen des Workshops stellten Wissenschaftlerinnen und Wissenschaftler europäischer Universitäten und internationaler Organisationen ihre neuesten Forschungsergebnisse zu aktuellen ökonomischen Fragen und Problemen vor und diskutierten diese intensiv. Insbesondere gab es einen regen Austausch über das Spezialthema „Challenges and Implications of Inflationary Dynamics“. Hier ging es vor allem um die Entwicklungen von Inflationserwartungen sowie mögliche Gründe und Folgen dieser Entwicklungen.

Qual VAR Revisited: Good Forecast, Bad Story

Makram El-Shagi Gregor von Schweinitz

in: Journal of Applied Economics, Nr. 2, 2016

Abstract

Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, originally proposed by Dueker (2005). The Qual VAR is a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonable well in forecasting (outperforming a probit benchmark), there are substantial identification problems even in a simple VAR specification. Typically, identification in economic applications is far more difficult than in our simple benchmark. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, use of the Qual VAR is inadvisable.

The Diablo 3 Economy: An Agent Based Approach

Makram El-Shagi Gregor von Schweinitz

in: 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.

Real Effective Exchange Rate Misalignment in the Euro Area: A Counterfactual Analysis

Makram El-Shagi Axel Lindner Gregor von Schweinitz

in: Review of International Economics, Nr. 1, 2016

Abstract

The European debt crisis has revealed severe imbalances within the Euro area, sparking a debate about the magnitude of those imbalances, in particular concerning real effective exchange rate misalignments. We use synthetic matching to construct a counterfactual economy for each member state in order to identify the degree of these misalignments. We find that crisis countries are best described as a combination of advanced and emerging economies. Comparing the actual real effective exchange rate with those of the counterfactuals gives evidence of misalignments before the outbreak of the crisis: all peripheral countries appear strongly and significantly overvalued.

Why They Keep Missing: An Empirical Investigation of Rational Inattention of Rating Agencies

Gregor von Schweinitz Makram El-Shagi

in: IWH-Diskussionspapiere, Nr. 1, 2017

Abstract

Sovereign ratings have frequently failed to predict crises. However, the literature has focused on explaining rating levels rather than the timing of rating announcements. We fill this gap by explicitly differentiating between a decision to assess a country and the actual rating decision. Thereby, we account for rational inattention of rating agencies that exists due to costs of reassessment. Exploiting information of rating announcements, we show that (i) the proposed differentiation significantly improves estimation; (ii) rating agencies consider many nonfundamental factors in their reassessment decision; (iii) markets only react to ratings providing new information; (iv) developed countries get preferential treatment.
