The provision of public goods in developing countries is a central challenge. This paper studies a model where each agent's effort provides heterogeneous benefits to the others, inducing a network of opportunities for favor-trading. We focus on a classical efficient benchmark – the Lindahl...

In this paper we show the benefits of regional connectivity and specialization to growth. Starting with one region we show how welfare measured by utility per head increases as the number of connected regions increase. We assume a common connectivity infrastructure implemented by satellite,...

This document, intended to be discuss and criticized, aims for the implementation on the city of Barreiro, Portugal, of a Local Investment Agency. The final objective of such project is to allow entrepreneurs and investors to build in the city new ventures that can create employment, build an...

A growing literature relies on natural experiments to establish causal effects in macroeconomics. In diverse applications, natural experiments have been used to verify underlying assumptions of conventional models, quantify specific model parameters, and identify mechanisms that have major...

In this paper, we analyze the role of cooperation between firms through a model of growth and social capital. In a growth model à la Solow we incorporate the set of resources that a relational network has at its disposals, as a distinct production factor, and thus examine its dissemination...

In this paper we show the benefits of regional connectivity and specialization to growth. Starting with one region we show how welfare measured by utility per head increases as the number of connected regions increase. We assume a common connectivity infrastructure implemented by satellite,...

We re-examine the literature on mobile termination in the presence of network externalities. Externalities arise when firms discriminate between on- and off-net calls or when subscription demand is elastic. This literature predicts that profit decreases and consumer surplus increases in...
