The nexus between firm growth, size and age in U.S. manufacturing is examined through the lens of quantile regression models. A number of interesting features are unveiled that linear frameworks could not detect. Size pushes both low and high performing firms towards the median rate of growth,...

This paper presents a model of international trade in differentiated intermediate goods. Because intermediates are invented through costly R&D investments, employing foreign intermediates implies sharing the return to R&D with the inventor country. We first derive how domestic productivity is...

Starting from CO2 emissions data collected during both the production phase and during the lifetime of cars and trucks, we argue that impressive opportunities to reduce emissions can be found in the consumption phase. It is however obvious that energy taxes alone will not lead to a strong...

The US government has decidedly moved towards encouraging co-operation in research and development (R&D) between firms, universities, and other research institutes since the early 1980s. The Republican Administration in the early 1980s set the stage for a radical shift in market environment...

This paper examines the link between imported technologies and a country's export performance, as measured by product quality. The analysis is set in the background of the process of regional integration between the EU and its neighbouring developing countries. The underlying question is whether...

The purpose of the present paper is to describe the role of uncertainty and technical change in an environmental context. Which impact does ecological uncertainty have on physical and R&D investments' decisions? How are pollution trajectories modified when uncertainty is taken into account? To...

In this paper we consider a model with two industrialised countries and immigrants that come from "the rest of the world". The countries are distinguished on the basis of three parameters: population size, bias towards immigrants, and production complementarity between native population and...

The present stalemate in climate negotiations has led policy analysts and economists to explore the possible emergence of alternative climate regimes. This paper explores the idea of replacing international cooperation on greenhouse gas emission control with international cooperation on...

The question of the spatial impacts of Information and Communication Technology (ICT) has animated intellectual and policy debate for a long time. At the beginning of the 1990s the advent of the Internet brought a new surge of debate: it was argued that the Internet would free the economy from...
