Hedge Fund returns are often highly serially correlated mainly due to illiquidity exposures given that investments in such securities tend to be inactively traded and associated market prices are not always readily available. Following that, observed returns of such alternative investments tend...

We propose new methods for estimating the bid-ask spread from observed transaction prices alone. Our methods are based on the empirical characteristic function instead of the sample autocovariance function like the method of Roll (1984). As in Roll (1984), we have a closed form expression for...

We develop and apply a new methodology in order to study the transmission mechanisms of international macroeconomic and financial shocks in the context of emerging markets. We propose a time-varying multi level factor augmented global VAR model which combines aspects of factor analysis and GVAR...

The present paper examines the degree of comovement of gross capital inflows, which is a highly sensitive issue for policy makers. We estimate a dynamic hierarchical factor model that is able to decompose inflows in a sample of 47 economies into (i) a global factor common to all types of flows...

Recent empirical evidence suggests that reversing current account balances imply costly adjustment processes leading to reduced economic growth. Using large panel data sets to analyze determinants and costs of reversals asks for controls of heterogeneity among countries. This paper contributes a...

This study analyses relative sectoral specialisation of EU regions on the basis of investment and employment patterns. Controlling for heteroscedasticity and potential endogeneity in the econometric analysis, we find that relative specialisation in manufacturing sectors is higher in central...

This paper analyzes the effects of public R&D funding on R&D expenditure and patenting behavior of German firms. The main focus is the direct impact of subsidies on R&D and the indirect effect on innovation output measured by patent applications. We distinguish the productivity of purely...

This study analyses relative sectoral investment patterns in EU regions. In an exploratory spatial data analysis, spatial clusters of high relative investments can be identified for some sectors. In the econometric analysis, we control for heteroscedasticity and potential endogeneity and find...

This paper analyses the level of relative specialisation in terms of gross fixed capital formation in EU regions. Larger market and regional sizes diminish; a higher unemployment rate, population density, the fact of being a central region, the distance to the economic centre, and economic...

This paper analyses the level of relative specialisation in terms of gross fixed capital formation in EU regions for the period between 1985 and 1994. Controlling for heteroscedasticity and potential endogeneity problems, we get consistent econometric results. Larger market and regional sizes...
