We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if there is some fully-allied group of countries that can defeat that country and its (remaining) allies based on a function of their...

We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two- city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when...

We compile a database of energy uses, energy sources, and carbon dioxide emissions for the USA for the period 1850-2002. We use a model to extrapolate the missing observations on energy use by sector. Overall emission intensity rose between 1850 and 1917, and fell between 1917 and 2002. The...

Stabilization of greenhouse gases at sustainable levels is the objective of the FCCC. Strategies to achieve this aim have been the object of intense debate. This paper focuses on one emissions trading system under scrutiny, Joint Implementation (JI). The basic premise of JI is that one nation...

The goal of the Framework Convention on Climate Change (FCCC) is to stabilize the concentration of greenhouse gases in the atmosphere at levels which avoid dangerous anthropogenic interference with the climate (United Nations, 1992). This paper examines the performance and cost characteristics...

Using an applied general equilibrium model, we explore the impacts of uniform reduction targets, a uniform carbon tax, and permit trading in the Annex 1 countries for the period 2000-2020. Next, we assess the impacts of enlarging the A-1 coalition to the globe, and allow for global permit...

This paper critically assesses the literature on the relationship between economic integration and the environment. In particular, we investigate how trade liberalisation and capital market integration affect environmental policy and thus environmental quality. Conversely, we also study how...
