Given the growing dissatisfaction with exclusion and long-run restrictions in structural vector autoregressive analysis, sign restrictions are becoming increasingly popular. So far there are no techniques for validating the shocks identified via such restrictions. Although in an ideal setting...

Using quarterly data from 2000-2007 and applying Error Correction Model and Johansen Co-integration Approaches I estimate the impact of real oil price on the real exchange rate of Azerbaijani manat. Estimation outputs derived from these approaches are very close to each other and indicate that...

This paper investigates the time-varying impact of oil price uncertainty on stock prices in China using weekly data on ten sectoral indices over the period January 1997-Febraury 2014. The estimation of a bivariate VAR-GARCH-in-mean model suggests that oil price volatility affects stock returns...

This paper estimates a bivariate VAR-GARCH(1,1) model to examine linkages between food and energy prices. The adopted framework is suitable to analyse both mean and volatility spillovers, and also allows for possible parameter shifts resulting from four recent events, namely: 1) the 2006 food...

In order to identify structural shocks that affect economic variables, restrictions need to be imposed on the parameters of structural vector autoregressive (SVAR) models. Economic theory is the primary source of such restrictions. However, only over-identifying restrictions can be tested with...

Benchmarking methods are widely used in the regulation of firms in network industries working under heterogeneous exogenous environments. In this paper we compare three recently developed estimators, namely conditional DEA (Daraio and Simar, 2005, 2007b), latent class SFA (Orea and Kumbhakar, 2004;...

In this paper, we analyze the technical efficiency of CO2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiencies in the transformation of inputs into desirable...

Gegenwärtig sind die verschiedenen Energieträger in Deutschland unterschiedlich stark mit Abgaben und Umlagen belastet. Um die energie- und klimapolitischen Ziele der Bundesregierung zu erreichen, müssen fossile Heiz- und Kraftstoffe stärker bepreist werden (Kemfert et al. 2019; Dertinger und...

The purpose of this contribution is to illustrate the mechanism by which higher oil prices might lead to lower interest rates in the context of a simple model that takes into account the global external savings equilibrium. The simple model has interesting implications for how one views the huge...

The global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both originate in the combination of economic policies adopted by the two key economies, the US and China. Global financial markets served as a transmission belt, both during the boom as during...
