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...

Sunk firing costs shelter employment and this effect is typically amplified by uncertainty due to an option value of waiting. Thus, if sunk firing costs are high, e.g. due to a employment protection legislation, and if recession related losses are with a high probability expected to be only...

A one-sector model of endogenous growth based on the accumulation of real capital by saving/investing and accumulation of human capital via learning-by-doing is presented. Experience is measured by means of production output aggregated over time. Explicitly separating learning and real capital...

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...

A model with two different production sectors and endogenous growth based on the accumulation of sector-specific human capital due to learning-by-doing is presented. Accumulation of experience is measured by means of sectoral production output aggregated over time. Growth is controlled by a...

Hysteresis in economics is up to now usually based on a representation of a system with only a single input variable, which has a persistent effect on an economic outcome (i.e. the output variable). However, in general there is more than one factor influencing economic decision problems, why the...

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 playhysteresis into a regression...

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...
