This paper analyzes volatility spillovers in multivariate GARCH-type models. We show that the cross-effects between the conditional variances determine the persistence of the transmitted volatility innovations. In particular, the influence of a foreign volatility innovation on a conditional...

Peat is a fossil material and is since decades the major growing media constituent for horticulture in Europe. Because of its climate impacts, some European countries developed national strategies to reduce peat use. A coordinated European action would bring fairer and more effective impacts...

Mixed-data sampling (MIDAS) regressions allow to estimate dynamic equations that explain a low-frequency variable by high-frequency variables and their lags. To account for temporal instabilities in this relationship, this paper discusses an extension to MIDAS with time-varying parameters, which...

Due to their well-known indeterminacies, factor models require identifying assumptions to guarantee unique parameter estimates. For Bayesian estimation, these identifying assumptions are usually implemented by imposing constraints on certain model parameters. This strategy, however, may result...

Consequences of path-dependent supply side hysteresis on the market equilibrium are illustrated. Supply is only a subsystem of the entire market with its forcing variable (price) being endogenous from the perspective of the entire market. This results in feedbacks on the equilibrium of price and...

Over millennia, mankind has used hard cash in various forms ranging from shells to gold coins and paper. More recently, cash has become unpopular in political circles, as it effectively restricts states’ power to tax (explicitly or via negative interest rates) or to survey and potentially...

We demonstrate that upward-looking comparisons induce "keeping up with the richer Joneses"-behavior. Using data from the German Socio-Economic Panel, we estimate the effect of reference consumption, defined as the consumption level of all households who are perceived to be richer, on household...

One important parameter in the decision process when buying a private annuity is individuals' subjective life expectancy, because it directly infuences the expected rate of return. We examine the market for private annuities in Germany and evaluate potential selection effects based on subjective...

Based on the German Socio-economic Panel (SOEP), we show that household consumption drops and saving rises significantly within four years after a child moves out of a household. Per capita consumption of parents is approximately leveled up to that of childless peers after all children are gone....

Das 1. Symposium für Ökonomie im Gartenbau fand am 27. November 2013 in der Paulinerkirche in Göttingen statt. Es wurde als Kooperation der Georg-August-Universität Göttingen, des Thünen- Instituts für Betriebswirtschaft und des Agrarkompetenznetzes WeGa durchgeführt. Die Veranstaltung...
