Does trade integration alter monetary policy transmission?

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies.     

Currency momentum strategies

We provide a broad empirical investigation of momentum strategies in the foreign exchange market. We find a significant cross-sectional spread in excess returns of up to 10% per annum (p.a.) between past winner and loser currencies. This spread in excess returns is not explained by traditional risk factors, it is partially explained by transaction costs and shows behavior consistent with investor under- and overreaction. Moreover, cross-sectional currency momentum has very different properties from the widely studied carry trade and is not highly correlated with returns of benchmark technical trading rules. However, there seem to be very effective limits to arbitrage that prevent momentum returns from being easily exploitable in currency markets.     

Common stochastic volatility trends in international stock returns

The aim of this work is to capture common stochastic trends in weekly volatilities of the Dow Jones, Nikkei, Hang Seng and Strait Times index using a multivariate stochastic volatility (SV) model. The results suggest a very high correlation among the volatility innovations, so that it is examined whether the four series share any common stochastic trends. A Principal Component Analysis and a Factor Analysis in the state space setting reveal that two common stochastic trends can be found to underlie the volatility series. The resulting linear combinations of the volatility series no more exhibit any stochastic trend but are stationary in the state space framework. Thus, it can be concluded that volatilities of the four stock indexes are in essence co-persistent.     

Actor and Institutional Dynamics in the Development of Multi-stakeholder Initiatives

As forms of private self-regulation, multi-stakeholder initiatives (MSIs) have emerged as an important empirical phenomenon in global governance processes. At the same time, MSIs are also theoretically intriguing because of their inherent double nature. On the one hand, MSIs spell out CSR standards that define norms for corporate behavior. On the other hand, MSIs are also the resultof corporate and stakeholder behavior. We combine the perspectives of institutional theory and club theory to conceptualize this double nature of MSIs. Based on a stage model that looks at the interplay of actor and institutional dynamics, we generate insights into why actors join a voluntary MSI, how the various motivations and intentions of the actors influence the standard development, and how these as well as the MSI design are subsequently influenced by both external (institutional) and internal (club) dynamics.     

Innovativer Energiespeicher Bundeswasserstraßen

The present analysis provides a contribution to the question of how a system integration of large-scale energy storages can be implemented. It is to be investigated if and how federal waterways can be used for this purpose. Initially, a baseline study was carried out in which the federal waterways are systematically assessed with regard to their suitability for/as energy storage systems. Apart from the technical and the hydro mechanical implementation of the storage process, the advantages and disadvantages of the federal waterways in comparison to conventional pump storage stations play a significant role. A presentation and classification of the potentially available canal sections provides an overview of the suitable storage systems of the federal waterways. A specifically designed storage simulation on the basis of a sample application is used, in order to determine the capacity of the canal system for energy storage. Consequently, the simulation showed the theoretical capability of the federal waterways as energy storage systems, through their ability to balance the load and temporal fluctuations of the energy input. The simulation program Matlab was used on the basis of the synthetic load and delivery profiles. Finally, based on the example of the ships lock in Uelzen and the Scharnebeck boats lift, a simulation of the possible re-equipping options will be described, technically abstracted, economically analysed and combined with renewable energy facilities within a virtual power plant. The detailed formulation of further approaches and the calculation of possible application scenarios play a central role within this analysis.     

The response of long-term interest rates to news about monetary policy actions: Empirical evidence for the U.S. and Germany

The Response of Long-Term Interest Rates to News about Monetary Policy Actions. Empirical Evidence for the U.S. and Germany. — The authors reestimate the expectations theory of the term structure focusing on the question of how monetary policy actions indicated by changes in the very short rate affect long-term interest rates. Their main point is that the expectations hypothesis implies that very long rates should only react to unanticipated changes of the very short rate. In contrast to cointegration tests of expectations theory, this implication only requires rational expectations but not stationary risk premia. Therefore, its empirical test sheds new light on the importance of expectations theory for the determinants of the term structure of interest rates.     

Factors of unsustainability: Identification,links and hierarchy

Although numerous, definitions of sustainable development remain vague or incomplete, living in an unsustainable world, it is more convenient to observe factors of unsustainability (FOUs) than to extrapolate to the conditions of sustainability. Furthermore, it would be more convenient to have a categorization of FOUs in order to correct them in a more direct way. To achieve this, the dynamics of FOUs have been studied within the scope of the business decision-making process, which can easily be extrapolated to other contexts. This analysis provides some recommendations with which to eliminate FOUs. The key points are cultural change by education, communication, continuous dialogue, learning and adaptation by the whole of society. Eliminating unsustainability does not always mean becoming sustainable. © 1998 John Wiley & Sons, Ltd and ERP Environment.
