Continued lobbying by high-end, American designers for intellectual property-type fashion design protection has culminated in the proposed Innovative Design Protection and Piracy Prevention Act, intended to introduce EU standards. Using a sequential, 2-firm, vertical differentiation framework,...

This paper studies the incentives that developing countries have to protect intellectual properties rights (IPR). On the one hand, free-riding on rich countries technology reduces their investment cost in R&D. On the other hand, firm that violates IPR cannot legally export in a country that...

In this paper, we offer a novel explanation to the surge in patenting bserved during the last years. With low patentability standards at PTOs (Patent and Trademark Offices awarding so-called bad patents), not only “false innovators” have the chance of being granted patents but also, and more...

This paper analyzes the optimal protection strategy for an innovator of a complex innovation who faces the risk of imitation by a competitor. We suppose that the innovation can be continuously fragmented into sub-innovations. We characterize the optimal mix of patent and trade secrets when 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...

We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly improve upon frontier technologies, and productivity improvements are drawn in a stochastic manner. The presence of positive knowledge spillovers implies that the decentralized...

For the first time we develop a time series of tax evasion (in % of official GDP) for 38 OECD countries over the period 1999 to 2010 based on MIMIC model estimations of the shadow economy. Considering indirect taxation and self-employment as the driving forces of tax evasion, we observe a...

This paper introduces a new measure of dependence or jointness among explanatory variables. Jointness is based on the joint posterior distribution of variables over the model space, thereby taking model uncertainty into account. By looking beyond marginal measures of variable importance,...

Slower growth of the labour force and an increase in old-age dependency will reduce the growth of aggregate output and output per capita in many developed countries. However, a major question is whether there is any systematic link between demographics and the productivity of those who will...

This paper presents the various methods to estimate the size of the shadow economy, their strengths and weaknesses. The purpose of the paper is twofold. Firstly, it demonstrates that no ideal method to estimate the size and development of the shadow economy exists. Because of its flexibility,...
