This paper develops a novel theory of trade in a global supply chain. We expand on a monopolistic competition trade model. Countries produce both intermediate and final goods that are sold domestically or, incurring country-pair specific trade costs, internationally. This links countries in a...

It is well established that incumbent firms may try to deter market entry by pretending to be stronger than they really are. In this article, we show that in some cases an incumbent may prefer the opposite, namely to encourage entry by signaling weakness. If the incumbent cannot deter entry of a...

Research and development (R&D) partnerships are formed to share the risks and benefits of R&D. At the macro level, they result in a globe-spanning network that can be a valuable source of international knowledge spillovers. This network is the subject of a considerable body of literature....

Empirical work shows that networks of research and development alliances are asymmetric, with a small number of firms involved in the majority of partnerships. This article investigates the welfare-relevant effects of such concentrated networks in a model of network formation in an oligopolistic...

Experimental economics has provided evidence for fairness concerns, but their relative strength and even their stability is still under debate. We reconcile the seemingly inconsistent results by presenting a theory of marginal fairness concerns. The key assumption is that fairness concerns are...

On the basis of a large (new) dataset of cities in Europe, North Africa and the Middle East in the millennium between 800 and 1800, we try to provide an answer to the question why, during this millennium, the urban center of gravity moved from Iraq (or more generally the Arab world) to Western...

Abstract This paper sheds empirical light on the relationship between agglomeration and economic growth and its impact on the convergence hypothesis. Using a sample of 208 European regions over 25 years, ‘standard’ growth regressions are estimated using panel data techniques. Both the effect...

To explain cross-country income differences, research has recently focused on the so-called deep determinants of economic development, notably institutions and geography. This paper sheds a different light on these determinants. We use spatial econometrics to analyse the importance of the...

Civil wars tend to cluster in particular areas of the world. We provide empirical evidence that cross-border conflict spillovers are an important factor in explaining this pattern. Moreover, we show that ethnicity plays a key role in conditioning the spread of civil wars. Only ethnic wars tend...
