The most fundamental proposition about growth and competition is that there is a tradeoff between static welfare and long-term growth. This paper reconsiders this basic proposition in an increasing product variety endogenous growth model with competitive markets for "old" innovative products and...

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...

Traditionally patents are seen as the gold standard for intellectual property protection. But, in line with empirical findings that secrecy is considered more important for appropriating returns, recent theories predict that firms keep their most important inventions secret. This article...

Patents have long been regarded as the 'gold standard' of intellectual property protection. In "Little patents and big secrets: managing intellectual property", Anton and Yao (2004) call this traditional view into question by finding that firms keep their most important innovations secret. This...

While economic theory suggests substitutability between labor and capital, little evidence exists regarding the causal effect of labor supply on inventing labor-saving technologies. We analyze the impact of exogenous changes in regional labor supply on automation innovation by exploiting an...

Big companies and small innovation factories possess different advantages in a patent contest. While large firms typically have a better access to product markets, small firms often have a superior R&D efficiency. In this paper I model a patent contest with asymmetric firms. In a pre-contest...

We investigate the impact of incremental trade liberalization in a dynamic model of endogenous growth with heterogeneous firms and costly trade. Growth originates from horizontal specialization and the steady state productivity growth rate is positive. Innovations require costly R&D and are...

This paper develops an endogenous growth model based on the idea of new combinations of input factors as a growth mechanism. The model integrates the idea of several technologies used simultaneously in producing final output. Innovations are of the horizontal and vertical type and in addition of...

Both mergers and innovation are central elements of a firm s competitive strategy. However, model-theoretical analysis of the merger-innovation link is sparse. The aim of this paper is to analyze the impact of mergers on innovative activities and product market competition in the context of...

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...
