Stochastic differential equations (SDE) are used as dynamical models forcross sectional discrete time measurements (panel data). Thus causal effectsare formulated on a fundamental infinitesimal time scale. Cumulated causaleffects over the measurement interval can be expressed in terms of the...

We analyze the effects of offshoring in a multisector-growth-model where the sectors differ by TFP-growth. Our results imply that offshoring influences the long run grwoth rate of the economy along different channels and that the grwoth effects depend on the development of terms of trade and on...

This paper introduces a new method for online estimation and predictionof states and parameters of nonlinear stochastic differential equations. Inthis setup parameters are considered as random variables in a Bayesiansense, which requires integration over parameter distributions. This...

The stock level in industrial companies is frequently subject of critical discussions. Material managers tendtowards high stock levels to ensure delivery and operational readiness. In contrast, controllers demand lowerstock levels to minimize the costs of capital commitment. This decision...

This paper studies the impact of labour taxation in a shirking model with wage bargaining.It is shown that if the ratio of unemployment compensation to the net-of-tax wage iskept fixed a tax cut leads to higher unemployment. When the unemployment benefitsreplacement ratio is allowed to change,...

This paper studies the optimal design of monetary policy in an optimizing two-country sticky price model. We suppose that the production sequence of final consumption goods stretches across both contries and is associated with vertical trade. Prices of final consumption goods are sticky in the...
