The legal monopoly granted by the patent system has often been criticized for its inefficiency, which is exacerbated by the peculiarities of knowledge as a public good. In this paper we aim at studying more deeply the latter concern. Hence we build a model in which monopolistic exploitation does...

We consider an endogenous growth model with two sectors: an intermediate input (or "upstream") sector and a final product (or "downstream") sector. Innovation takes place in both sectors. Following Gilbert and Shapiro (1990), we define patent breadth as the ability of the innovator to reap...

We examine the timing and quality of product introduction in an R&D stopping game, where we allow for horizontal and vertical differentiation in the product market. We observe that discontinuous changes in introduction dates can occur as firms' abilities as researchers change. Further, when the...

This article presents an empirical model of non-stationary and cointegrated panel data to explain the impact of industrial property, measured by patents, on the GDP of 10 Latin America countries during the period 1990 to 2010. Apply traditional unit root tests and unit root test of art, which...

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...

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...

This paper constructs an analytically tractable model of endogenous innovation with a special focus on the effects of barriers to entry, namely patents. Conventional models of endogenous growth rely on the existence and enforcement of intellectual property rights with patents. Those legal rights...

This paper analyzes the effects of a varying patent strength on the incentives to undertake cost-saving innovations in a product-variety model with hierarchical preferences. If the majority of the agents does not derive profit income from patents, a reduction in patent strength can lead to an...
