We model biological invasions as an unintended by-product of capital accumulation. We distinguish three spillover effects: (1) a negative production externality, (2) a negative or positive consumption externality and (3) an increase in the risk of future welfare loss. We also consider the...

Remittances to developing countries exceed $550 billion annually. Although many poor rural households that depend on these remittances also harvest local common-pool resources, few studies explore this relationship. We develop a dynamic model of a coastal fishing household with remittance...

We model biological invasions as an unintended by-product of capital accumulation. We distinguish three spillover effects: (1) a negative production externality, (2) a negative or positive consumption externality and (3) an increase in the risk of future welfare loss. We also consider the...

This paper explores the value of mangrove systems as a breeding and nursery habitat for off-shore fisheries, focusing on mangrove-shrimp production linkages in Campeche State, Mexico. We develop an open access fishery model to account explicitly for the effect of mangrove area on carrying...

There is now increasing recognition that the world's marine ecosystems, especially coastal areas and semi-enclosed seas, are suffering from degradation and modification due to human influences. One of the most serious problems is nutrient enrichment, which in the long term harms productivity and...

An important evaluation problem in developing countries is assessing the value and optimal use of environmental resources as inputs into production. This is a key methodology required for many general evaluation approaches, e.g. ensuring the most efficient use of a resource requires...

This paper explores the link between poverty and resource allocation, including the management of natural resources, by chronically indebted rural smallholders in developing countries. The paper proposes a formal intertemporal model of a credit constrained farm household that can invest in...

Nutrient enrichment of marine ecosystems is regarded as a pressing global environmental problem. For certain marine species it may be a mixed blessing, resulting in damaging ecosystem events, but contributing to primary productivity. Consequently, the impact of enrichment on fishery profits may...

This paper uses panel analyses to estimate relationships for agricultural planted area and beef cattle numbers at the state level in Mexico during the periods 1970-85, in order to determine the main factors affecting forest land conversion. Of the key policy variables, maize and fertilizer...

This paper both introduces the special issue on the economics of tropical deforestation and land use and conducts a synthesis crosscountry analysis of tropical agricultural land expansion. Agricultural development is the main factor determining land expansion, but institutional factors have an...
