The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of...

The world has pledged to protect 30 percent of its land and waters by 2030 to halt the rapid deterioration of critical ecosystems. We summarize the state of knowledge about the impacts of protected area policies, with a focus on deforestation and vegetation cover. We discuss critical issues...

The pace of biodiversity loss requires drastic shifts in conservation efforts that carry substantial costs. We investigate how the financial market prices such conservation costs exploiting the "Green Shield Action," a major regulatory initiative launched by the Chinese central government in...

We estimate the impact of the COVID-19 crisis on business failures among small and medium size enterprises (SMEs) in seventeen countries using a large representative firm-level database. We use a simple model of firm cost-minimization and measure each firm's liquidity shortfall during and after...

This paper discusses the likely evolution of the trade and environment issue in the World Trade Organization after the upcoming ministerial meeting in Singapore this December. It makes a number of points. Progress within the GATT/WTO on this issue looks likely to be slow and painfully...

By reducing the costs of environmental protection, technological change is important for promoting green growth. This entails both the creation of new technologies and more widespread deployment of existing green technologies. This paper reviews the literature on environmentally friendly...

The purpose of this paper is to introduce the concept of power density [Watts/m²] into economics. By introducing an explicit spatial structure into a simple general equilibrium model we are able to show how the power density of available energy resources determines the extent of energy...

Green growth is about making growth resource-efficient, cleaner and more resilient without slowing it. This paper aims at clarifying this in an analytical framework and proposing foundations for green growth. This framework identifies channels through which green policies can potentially...

This chapter applies recent research on environmental enforcement to a potential U.S. program to control greenhouse gases, especially through emission trading. Climate policies present the novel problem of integrating emissions reductions that are relatively easy to monitor (such as carbon...
