Empirical studies on price transmissions between North American and European agricultural futures neglect the period of financialization in the US commodity market, the increase of futures trading in Europe and the recent price turmoils. We fill this gap by analyzing the price dynamics of...

In case of herding, investors follow each other, prices move together more than they normally do, and the cross-sectional dispersion of returns decreases. Chang, Cheng, and Khorana (2000) suggest to test for herding by regressing the cross-sectional absolute deviation on the absolute and squared...

In the context of the present-value stock-price model, we propose a new rational parametric bubble specification that is able to generate periodically recurring and stochastically deflating trajectories. Our bubble model is empirically more plausible than its predecessor variants and has neatly...

It is still an unanswered question how much trading activity is needed for efficient price discovery in commodity futures markets. For this purpose, we investigate the price discovery process of two thinly traded agricultural futures contracts traded at the European Exchange in Frankfurt. Our...

We introduce a forecasting method that closely matches the econometric properties required by the theory on exchange rate prediction. Our approach formally models (i) when (and if) explanatory variables enter or leave a regression model, (ii) the degree of parameter instability, (iii) the...

The Gain-Loss-Ratio, proposed by Bernardo and Ledoit (2000), evaluates the attractiveness of an investment opportunity for an investor with a given stochastic discount factor. It can either be used as a performance measure on a market with known prices or to derive price-intervals in incomplete...

This paper introduces a Bayesian version for Dynamic Model Averaging for predicting aggregate stock returns. Our suggested approach simultaneously accounts for many sources of uncertainty. It is designed to handle (i) parameter instability, (ii) time-varying volatility, (iii) model uncertainty...

Several formal methods have been proposed to check local identification in linearized DSGE models using rank criteria. Recently there has been huge progress in the estimation of non-linear DSGE models, yet formal identification criteria are missing. The contribution of the paper is threefold:...

This paper challenges the existing literature examining the impact of the introduction of index futures trading on the volatility of its underlying. To overcome econometric shortcomings of previously published work using the dummy variable approach, we employ a Markov-switching-GARCH technique....

This paper estimates equilibrium rates of macroeconomic aggregates for small open economies. We simultaneously identify the transitory and permanent components of output, inflation, the interest rate and the exchange rate by means of a multivariate trend-cycle decomposition. Realizations of the...
