We argue that the complex interactions of competitive heterogeneous firms lead to a statistical equilibrium distribution of firms? profit rates, which turns out to be an exponential power (or Subbotin) distribution. Moreover, we construct a diffusion process that has the Subbotin distribution as...

In this paper, we explore a dynamical version of by Aoki and Yoshikawa model (AYM) for an economy driven by demand. We show that when an appropriate Markovian dynamics is taken into account, AYM has different equilibrium distributions depending on the form of transition probabilities. In the...

Diese Arbeit beschäftigt sich mit speziellen Aspekten der stochastischen Überlagerung, die als Anonymisierungsmethode zur Sicherstellung der faktischen Anonymität von Mikrodaten eingesetzt wird.2 Insbesondere soll der Zusammenhang zwischen der Überlagerung mittels einer Mischungsverteilung...

Die Arbeit betrachtet die Auswirkungen von additiver und multiplikativer Überlagerung mit Messfehlern auf die Schätzung linearer Modelle. Dabei erfolgt diese Überlagerung geplant mit dem Ziel der Anonymsierung von Mikrodaten. Im Mittelpunkt steht die Überlagerung mittels einer (bimodalen)...

We propose a test of the hypothesis of stochastic monotonicity. This hypothesis is of interest in many applications in economics. Our test is based on the supremum of a rescaled U-statistic. We show that its asymptotic distribution is Gumbel. The proof is difficult because the approximating...

When analysing the volatility related to high frequency financial data, mostly non-parametric approaches based on realised or bipower variation are applied. This article instead starts from a continuous time diffusion model and derives a parametric analog at high frequency for it, allowing...

Many structural econometric models include latent variables on whose probability distributions one may wish to place minimal restrictions. Leading examples in panel data models are individual-specific variables sometimes treated as "fixed effects" and, in dynamic models, initial conditions. This...

European economic integration is commonly believed to be incomplete, and that further reforms are needed. In this context, the union of U.S. states is considered the benchmark of complete economic integration and is often the basis for comparison regarding the extent of E.U economic integration....
