We study an asymmetric triopoly in a heterogeneous product market where quantity decisions are delegated to managers. The two biggest firms are commonly owned by shareholders such as index funds while the smallest firm is owned by independent shareholders. Under such a common holding owner...

The paper studies a two-stage location-price duopoly game in a disk city with consumer concentration around the city center. When consumers are uniformly distributed over the plane, unconstrained firms locate outside of the city. Consumer concentration, however, induces firms to locate nearer to...

In a capacity-then-price-setting game we experimentally identify capacity precommitment, the possibility to communicate before price choices, and prior competition experience as crucial factors for collusive pricing. The theoretical analysis determines the capacity thresholds above which firms...

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...
