This paper studies the evolution of city population and the land use policy in China. We show that the population distribution of cities in China tends to cluster around 2-8 million people, and the distribution has become more clustered in recent years. Using a general equilibrium urban model,...

This paper examines the strategic rationale behind the formation of Canada's Oil Sands Innovation Alliance (COSIA). COSIA's members account for ninety percent of the total production in the Oil Sands. COSIA's main goals are to improve the industry's environmental performance and to increase oil...

We study the effects of environmental policy commitments in a futuristic world in which solar radiation management (SRM) can be utilized to reduce climate change damages. Carbon and sulfur dioxide emissions (correlated pollutants) can be reduced through tradable permits. We show that if both...

We examine the formation of hub-and-spoke and multilateral green technology international agreements. Green R&D provision produces two types of positive externalities, a global public good (i.e., reduction of carbon dioxide emissions) and spillovers in technology agreements. We utilize the...

The Perfectly Coalition-Proof Nash equilibrium (PCPN) concept is extended to allow for the emergence of overlapping coalitions in equilibrium. We apply the extended concept to study the efficiency and stability properties of environmental agreements to control emissions of correlated continental...

This paper is the first systematic examination of (counter)terrorism dynamic games with two types of externalities: temporal and spatial. We consider two types of non-cooperative behavior; one in which national authorities are sensitive with respect to the spatial spillovers of counterterror...
