Regulatory reforms across European countries have attempted to increase consumer welfare by introducing competition and choice into public service markets. But it has been questioned whether reforms have benefited all people equally, suggesting that vulnerable groups of service users are...

There is the possibility to affirm on a very surprising (methodological) equivalence, beyond a historian space-time, between two important attempts toward the forever difficult "problem solving": I: Consolation of Philosophy, by Roman philosopher and mathematician Boetius (ca. 480–524 or 525),...

This paper analyzes the patenting decision of a successful inventor in a model of dynamic technology adoption with asymmetric firms. We show that the extent of the inventor's technological headstart is decisive for his patenting behavior. The overall patenting effect consists of two parts, a...

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

I study the incentives of Cournot duopolists to share their technologies with their competitor in markets where intellectual property rights are absent and imitation is costless. The trade-off between a signaling effect and an expropriation effect determines the technology-sharing incentives. In...

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...

In the ICT sector, product-software is an important factor for the quality of the products (e.g. cell phones). In this context, open source software enables firms to avoid quality competition as they can cooperate on quality without an explicit contract. The economics of open source (OS) versus...

Recent evidence on world trade patterns reveals North-South specialization across products of the same industries and product groups but different quality, which is not matched by the predictions of traditional and new trade theory. This paper analyzes a model of North-South trade and endogenous...

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 paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy-efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes,...
