The question this paper addresses is how the market structure evolves due to innovative activities when firms' level of technological competence is valuable for more than one project. The focus of the work is the analysis of the effect of learningbydoing and organizational forgetting in R&D on...

This paper presents a general-equilibrium model of endogenous skilled-biased technological change and matching unemployment in a disaggregated economy. We simultaneously endogenise both the direction and pace of technological change as well as the unemployment rates. We show that an increase in...

We extend the standard quality-ladder model with heterogeneous workers by including efficiency wages and unions. We find that higher union bargaining power leads to a negative relationship between growth and unemployment. An increase in the supply of human capital, however, on the one hand...

Capital accumulation and creative destruction is modeled together with risk-averse households. The novel aspect - risk-averse households - allows to use well-known models not only for analyzing long-run growth as in the literature but also short-run fluctuations. The model remains analytically...

This paper offers a comprehensive study on transitional dynamics within R&D-based models of endogenous growth. There are two main motivations. First, the complete dynamic system for the market solution is derived in general form. Second, using this dynamic system as a unifying framework the...

This paper analyzes the effects of new business formation on industry growth. Dynamic panel techniques are used to test two hypotheses. First, does hit-andrun competition secure efficiency in an industry? Second, do innovative startups lead to amplified innovations by diminishing the knowledge...

We develop an endogenous growth model with capital, labor and energy as production factors and three productivity variables that measure accumulated innovations for energy production, energy savings, and neutral growth. All markets are complete and perfect, except for research, for which we...

We develop an economic model for fossil-fuel and carbon-free energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. We use the model to study inter-temporally efficient carbon taxes for...

We develop a partial one-sector model with capital, natural resources, and labor as production factors, and endogenous technological change through research. Production exhibits increasing returns to scale. We compare the response of output and resource use to a change in resource prices with...

We develop an economic partial equilibrium model for energy supply and demand with capital and labor as production factors, and endogenous technological change through learning by research and learning by doing. Our model reproduces the learning curve typical for (bottom-up) energy system...
