This paper investigates the dimension requirements of informationally decentralized Pareto-satisfactory processes in production economies with increasing returns to scale or more general types of non-convexities. We show that the marginal cost pricing (MCP) mechanism is informationally effcient...

Recent theoretical advances have emphasised the importance of localised increasing returns to scale in understanding both the regional growth and agglomeration processes. However, considerable empirical controversy still exists over whether returns to scale are constant or increasing....

In this paper I present an explanation to the fact that in the data wealth is substantially more concentrated than income. Starting from the observation that the composition of households' portfolios changes towards a larger share of high-yield assets as the level of net worth increases, I first...

In this paper we analyse how the distribution of land property rights affects industrial takeoff and aggregate income through its impact on effective demand. We apply a modified version of the model provided in Murphy et al. (1989, QJE) which allows us to analyse the role of land distribution...

The role played by endogenous growth models in growth literature might be analyzed from two perspectives. In the first place, is it emphasized the necessity to replace the hypothesis of perfect competition with monopolistic competition in every mathematical model. Secondly, there is no...

From its early days, the World Wide Web space has demonstrated strong agglomeration trends with a very small number of web sites capturing the larger part of the Internet population. At a first glance, agglomeration over the virtual space sounds as a paradox. Web sites are numerous and highly...

We address the notion of dynamic, endogenous diversity and its role in theories of investment and technological innovation. We develop a formal model of an innovation arising from the combination of two existing modules with the objective to optimize the net benefits of diversity. The model...
