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...

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...
