Summary Based on a stochastic dynamic model of a firm's optimal innovative behavior we derive a simultaneous equation system for product and process innovations with intertemporal spillover effects. We estimate various versions of the model with dichotomous innovation data at the firm level by...

Summary Based on an extended game-theoretic innovation-race model, we derive some Schumpeterian hypotheses of the impact of technological rivalry, market power, technological opportunities and demand expectations on the timing of product and process innovations. Using innovation data at the firm...

Summary The paper presents a dynamic general-equilibrium model of education, quality and variety innovation, and scale-invariant growth. We consider endogenous human-capital accumulation in an educational sector and quality and variety innovation in two separate R&D sectors. In the balanced...

Abstract We study product market competition between firm owners (principals) where workers (agents) decide on their efforts and, hence, on output levels. Various worker compensation schemes are compared: a piece-rate compensation as a benchmark when workers’ output performance is verifiable,...

We study interaction effects between intra-firm conflicts and interfirm competition on a duopolistic market with seller firms employing one or more agents and implementing tournament incentives. We show that inter-firm competition leads to higher incentive intensity, higher efforts and output...

In two-person generosity games the proposer's agreement payoff is exogenously given whereas that of the responder is endogenously determined by the proposer's choice of the pie size. Earlier results for two-person generosity games show that participants seem to care more for efficiency than for...
