This report assesses conceptually and empirically the extent to which the stringency of environmental regulations drives international trade in environmental goods. Many of the measures governments adopt to address issues such as local air and water pollution or GHG emissions take the form of...

Many developing countries depend crucially on open-access renewable natural resources (NR). Trade is generally viewed as hurting the long-term health of NR in commodity-exporting countries. I examine whether trade might be beneficial in the case of population growth. Dynamic general equilibrium...

Production of commodities based on open-access renewable natural resources (NR) has usually been examined under "low" congestion (LC) - where MC AC and both increase with output. I identify two additional congestion categories, "high" (HC) and "super" (SC) congestion - where AC is...

Numerous developing economies depend vitally on renewable natural-resource (NR)-based commodities. This study develops a general equilibrium model to examine the steady-state impact of changes in a small economy's NR congestion under open access and optimal regulation. This issue has often been...

Many developing countries depend crucially on open-access renewable natural resources (NR). Trade is generally viewed as hurting the long-term health of NR in commodity-exporting countries. I examine whether trade might be beneficial in the case of population growth. Dynamic general equilibrium...

The natural capital concept is generating broad interest that extends well beyond economists. Economics has a long history of applying capital theory to natural resources. However, measurement of the value of ecosystems has mostly focused on income flows rather than valuing stocks of natural...

This article discusses the aggregation problem and its implications for ecological economics. The aggregation problem consists of a simple dilemma: when adding heterogeneous phenomena together, the observer must choose the unit of analysis. The dilemma is that this choice affects the resulting...

Investment arbitration was originally developed primarily to protect investors from wealthy developed countries against arbitrary expropriations by governments in developing countries. However, over time, it has taken on a very broad dynamic and is nowadays often used to limit regulatory...

A major concern in climate negotiations is that decarbonization may significantly hurt the development process. This paper shows that international specialization can contribute to making environmental and economic objectives compatible. When carbon efficiency differs between two trading...

A spatial welfare framework for the analysis of the spatial dimensions of sustainability is developed. It incorporates agglomeration effects, interregional trade, negative environmental externalities and various land use categories. The model is used to compare rankings of spatial configurations...
