In this paper the long-run effects of demand and recharge uncertainty on the socially optimal management of groundwater reserves are studied. Demand uncertainty is modeled in a dynamic framework by letting the demand function shift randomly but continuously through time according to a random...

The Kyoto protocol allows Annex I countries to deduct carbon sequestered by land use, land-use change and forestry from their national carbon emissions. Thornley and Cannell (2000) demonstrated that the objectives of maximizing timber and carbon sequestration are not complementary. Based on this...

Climatic changes will affect the dynamics of a forest ecosystem. Consequently, carbon sequestration costs can only be estimated correctly if changes in climatic conditions are considered. This article determines the changes in mitigation costs of an optimal forest management regime in the...

This paper makes a proposal for a taxonomy of boundary changes in Spanish municipalities along time. The different types of changes are organized in a hierarchy, as well as represented in a homogeneous manner, independently of the number of municipalities involved and of the changes suffered....

This paper provides empirical evidence on the relationship between indicators of competitive pressure and innovation incentives using panel data of Spanish manufacturing firms for the period 1990-2006. Instead of using standard indicators of competition, such as market concentration measures or...

During the years of crisis, Spain’s autonomous communities have experienced a significant general increase in their deficits and, until 2012, have had severe difficulties to control them. Their debts have grown strongly and are considered the most worrying element of Spain’s public finance...

This paper aims to contribute to the literature on New Economic Geography by providing empirical evidence for the connections between new trade theory and the spatial distribution of economic activities. To do this, we apply Social Network Analysis specifically to the World Automotive Trade...

This paper presents an exercise in the definition of cities from clear and explicit quantitative criteria. The city concept is linked to the local political level, so in this sense we can talk about “administrative cities”, since they are formed by one municipality, or a group of them that...
