Public policy work is hard, especially when one works in developing countries. It is even difficult to define what success looks like, and thus how to manage towards success. Literature helps manage such difficulty, providing studies that define the concept and show how it can be achieved. A...

Development economics is split between macro-development economists - who focus on economic growth, international trade, and fiscal/macro policies - and micro-development economists - who study microfinance, education, health, and other social programs. Recently there has been substantial...

The bulk of global inequality is accounted for by income differences across countries rather than within countries. Expanding trade with China has aggravated inequality in some advanced economies, while ameliorating global inequality. But the “China shock” is receding and other low-income...

The seminal contributions of William Nordhaus to scholarship on the long-run macroeconomics of global climate change are clear. Much more challenging to identify are the impacts of Nordhaus and his research on public policy in this domain. We examine three conceptually distinct pathways for that...

The Paris Agreement has achieved one of two key necessary conditions for ultimate success – a broad base of participation among the countries of the world. But another key necessary condition has yet to be achieved – adequate collective ambition of the individual nationally determined...

Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level. At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful...

We examine an implication of the “Coase Theorem” which has had an important impact both on environmental economics and on public policy in the environmental domain. Under certain conditions, the market equilibrium in a cap-and-trade system will be cost-effective and independent of the...

We describe the major features of a post-2012 international global climate policy architecture with three essential elements: a means to ensure that key industrialized and developing nations are involved in differentiated but meaningful ways; an emphasis on an extended time path of targets; and...

We describe three essential elements of an effective post-2012 international global climate policy architecture: a means to ensure that key industrialized and developing nations are involved in differentiated but meaningful ways; an emphasis on an extended time path of targets; and inclusion of...
