This paper analyzes the implications of advertising for firm dynamics and economic growth through its interaction with R&D investment at the firm level. We develop a model of endogenous growth with firm heterogeneity that incorporates advertising decisions. We calibrate the model to match...

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...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

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 learning-by-doing and organizational forgetting in R&D on...

This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving in-novation that incorporates industries with heterogeneous innovation sizes. Government de-mand in high-tech industries...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

I model knowledge (patent) licensing and evaluate intellectual property regulation in an endogenous growth framework where the engine of growth is in-house R&D performed by high-tech firms. I show that high-tech firms innovate more and economic growth is higher when there is knowledge licensing,...
