Argumente gegen die Reform des Stabilitätsgesetzes wenig überzeugend — eine Replik

In their reply, Dullien and van Treeck criticise the argument of Michaelis, Elstner and Schmidt that the German Stability and Growth law (StabG) from the 1960s must not be reformed. They claim that Michaelis et al. neglect that the concept of sustainability has changed over the past 50 years and that nowadays issues such as social and ecological sustainability should be included. Moreover, the claim by Michaelis et al. that the StabG provides important tools for business cycle management is hardly convincing, given that these tools have not been used since the 1970s and stimulus packages have been passed on other legal grounds. / In their response Michaelis et al. stress that economic policy has to consider equally aspects of economic, social and ecological sustainability. The StabG, however, is a completely inappropriate basis for attempts to address aspects of social and ecological sustainability. The main use of the StabG consists in the possibility to quickly implement fiscal measures that could mitigate the consequences of severe economic downturns. Proposals of Dullien and van Treeck that various dimensions of sustainability are controllable by a predetermined set of instruments neglect the complexity of the social market economy.     

Experimental investigation of stationary concepts in cyclic duopoly games

We experimentally test the predictive success of three stationary concepts in two cyclic duopoly games. The concepts are Nash equilibrium, impulse-balance equilibrium and payoff-sampling equilibrium. In the experiment 11 independent subject groups, consisting out of six participants interacting over 200 rounds, were gathered for each game. The comparison of the three concepts with mixed strategies shows that the order of performance from best to worst is as follows: payoff-sampling equilibrium, impulse-balance equilibrium, and Nash equilibrium. In addition the data exhibit a weak but significant tendency over time in the direction of coordination at a pure strategy equilibrium.     

(No) Limits to Anglo-American accounting? Reconstructing the history of the International Accounting Standards Committee: A review article

The development of the current International Accounting Standards Board (IASB) from the earlier International Accounting Standards Committee (IASC) provides insight into many issues of international financial reporting, among them the characteristics of international accounting standards themselves. This article reviews Camfferman and Zeff’s [Camfferman, K., & Zeff, S. A. (2007). Financial reporting and global capital markets. A history of the international accounting standards committee 1973–2000. Oxford: Oxford University Press] volume on the organizational development of the IASC and contextualizes it in the broader literature of cross-border standardization in accounting. While having produced a seminal piece, the authors take a clear Anglo-American perspective. The downsides are insufficiencies regarding a simplistic understanding of experts and expertise, a neglect of the role of auditing firms, and only an imbalanced integration of different stakeholders.     

Hedge-Fonds als Asset-Klasse: Betrachtungen aus der Perspektive der deutschen Versicherungswirtschaft

The over performance of hedge funds until the current financial market turbulences led to a large number of insurers increasing their hedge funds quota. In the following this asset class is examined and particularly analyzed with respect to its adequacy for an insurance company's asset allocation by focusing on the axiom of safety, as demanded by national law. The problem of survivorship-bias and the Markowitz requirements of normal-distribution and constant correlations among the asset classes and their impact on a strategic asset allocation are studied.     

EXCHANGE RATE MISALIGNMENT IN DEVELOPING COUNTRIES

This article analyzes the theory of equilibrium real exchangerates and defines misalignment as a deviation of the real exchangerate (RER) from its equilibrium level. The role of macroeconomicpolicies is then analyzed under three alternative nominal exchangerate regimes: predetermined nominal exchange rates, floatingnominal rates, and dual or black market nominal exchange rates.This discussion points out how inconsistent macroeconomic policiesoften lead to real exchange rate misalignment. Corrective measures,including nominal devaluations and several alternative approaches,are then evaluated.      

Price relationships between qualitatively differentiated agricultural products: organic and conventional wheat in Germany

Organic agriculture, which produces commodities that can be qualitatively differentiated from conventional food products, has grown into an important market in many countries. The dynamics of commodity prices in both sectors are partly interdependent, but are also shaped by independent determinants and have rarely been studied. We analyze organic food markets and their interdependencies with conventional markets in the context of wheat markets in Germany, which have been subject to a number of fundamental changes during the last two decades. Based on institutional market characteristics, we suggest a flexible Markov‐switching asymmetric time series model. We find a pronounced temporal sequence of market phases that differ in their asymmetric dynamics and the extent to which the organic price is influenced by the conventional price. Organic wheat prices tend to be increasingly connected to prices of conventional wheat.

Too Many Cooks? Committees in Monetary Policy

How many people should decide monetary policy? In this article, we take an empirical perspective on this issue and analyze the relationship between the number of monetary policy decision makers and monetary policy outcomes. Using a new data set that characterizes central bank monetary policy committees (MPCs) in more than 30 countries from 1960 through 2006, we find a U‐shaped relationship between MPC size and inflation; our results suggest that the lowest level of inflation is reached at MPCs with an intermediate size of about five to nine members. Similar results are obtained for inflation variability. Other MPC characteristics also matter for monetary policy outcomes, though to a smaller degree. For instance, the membership composition of the MPC as well as the frequency of MPC membership turnover appears to affect economic variables.
