With the extension of its competence for social policy legislation in the Maastricht and Amsterdam treaties, the EU has adopted a significantly new social dimension in the past ten years. According to the Copenhagen criteria, the CEEC candidate countries have to adopt the former via the acquis...

In a baseline micro model a band of inaction due to hiring- and firing-costs is widened by option value effects of exchange rate uncertainty. Based on this micro foundation an aggregation approach is presented. Under uncertainty, intervals of weak response to exchange rate reversals (called...

A simple model evaluating a firm’s optimal employment reaction to an imminent recession is presented. Firing costs shelter employment – and this effect is typically amplified by uncertainty due to an option value of waiting. However, this job protection effect is reduced if the expected...

Efficiency wage effects of profit sharing are combined with option values related to stochastic future profit variations. These option effects occur if the workers' profit share is fixed by long-term contracts. The Pareto-improving optimal level of the sharing ratio is calculated for two...

This paper deals with the impact of the $/€ exchange rate on German exports in the period from 1995Q1 to 2008Q4. Our main aim is to identify 'pain thresholds' for German exporters. We rely on a non-linear model according to which suddenly strong spurts of exports occur when changes of the EXR...

Efficiency wage effects of profit sharing are combined with option values related to stochastic future pofit variations. These option effects occur if the workers' profit share is fixed by long-term contracts. The Pareto-improving optimal level of the sharing ratio is calculated for two...

A non-linear model is applied where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction. We call the latter a 'play' area - analogous to mechanical play and implement an algorithm describing path-dependent play-hysteresis into a regression...

Relations between economic variables are often characterized by a situation where initial conditions and the past realizations of economic variables matter. I.e. past (transient) exogenous disturbances and past states of the economic system do have an influence on the current economic relations....

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...

Transition from one economic equilibrium to another as a consequence of shocks is often associated with sunk adjustment costs. Firm specific sunk market entry investments (or sunk market exit costs) in case of a reaction to price shocks are an example. These adjustment costs lead to a dynamic...
