This paper is an attempt to develop a unified approach to endogenous heterogeneity by constructing general class of two-player symmetric games that always possess only asymmetric pure-strategy Nash equilibria. These classes of games are characterized in some abstract sense by two general...

We study robustness of the model of demand driven innovation and spatial competition over time with log-concavely distributed signals in Jovanovic and Rob (1987) to heavy-tailedness assumptions. We demonstrate that implications of the model remain valid for not extremely heavy-tailed...

Companies that want to grow face a fundamental dilemma: They can only increasetheir current base of sales substantially if they introduce really new products into themarket. However, the risk of a market failure also increases with the degree of innovativenessof the product (Booz, Allen &...

In this paper we study the welfare effect of a monopoly innovation. Unlike many partial equilibrium models carried out in previous studies, general equilibrium models are constructed and analyzed in greater detail. We discover that technical innovation carried out by a monopolist could...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behavior of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...

In this paper, we use a CGE model with endogenous growth to study the interplay between environmental regulation, innovation and sectoral growth. We find that a stringent reduction target for carbon emissions combined with a CO2-tax leads to structural changes. Under the assumption of a...
