Why should multilateral lending exist in a world where private capital markets are well developed and governments have their own bilateral aid programs? If lending by the World Bank, IMF, and regional development banks has an independent rationale, it must rest on advantages generated by the...

The accumulation of international reserves by emerging markets raises the question of how to best utilize these funds. This paper explores two routes through which the pooling of reserves could enhance stability and welfare. First, the reserve pool could be used for emergency lending in response...

This paper looks at the problem of making multiple lending decisions which affect the supply of the product when the consequences of these lending decisions are interrelated via the effect on the world price of the product. This is termed the 'adding up problem'. It is argued that thinking of...

Re-orienting current energy systems toward a far greater reliance on technologies with low or no carbon dioxide emissions is an immense challenge. At the broadest level the histories presented here are very much consistent with widely held views within the energy innovation policy literature. In...

Energy efficiency improvements “rebound” when economic responses undercut their direct energy savings. I show that general equilibrium channels typically amplify rebound by making consumption goods cheaper but typically dampen rebound by increasing demand for non-energy inputs to production...

Within the field of environmental economics, the role of technological change has received much attention. The long-term nature of many environmental problems, such as climate change, makes understanding the evolution of technology an important part of projecting future impacts. Moreover, in...

The most cost-effective policies for achieving CO2 abatement (e.g., carbon taxes) fail to get off the ground politically because of unacceptable distributional consequences. This paper explores CO2 abatement policies designed to address distributional concerns. Using an intertemporal numerical...

Historically, innovation in the energy sector proceeded slowly and entrepreneurial start-up firms played a relatively minor role. We argue that this may be changing. Energy markets are going through a period of profound structural change. The rise of hydrofracturing lowered fossil fuel prices so...

To reliably achieve deep decarbonization of the US power sector, a candidate policy must perform robustly across a range of possible future trajectories of demand, fossil fuel prices, and prices of new wind and solar capacity. Using a modified version of the NREL ReEDS model with scenarios that...

This paper deals with three important issues related to real exchange rates. First, it discusses the analytical concept of real exchange rate (RER) placing particular emphasis on providing an operational definition for the equilibrium real exchange rate. Of course, once this concept is defined...
