In cross-sectional studies, countries with greater income inequality typically exhibit less support for government-led redistribution and greater acceptance of wage inequality (e.g., United States versus Western Europe). If individual nations evolve along this pattern, a vicious cycle could form...

While vote-buying is common, little is known about how politicians determine who to target. We argue that vote-buying can be sustained by an internalized norm of reciprocity. Receiving money engenders feelings of obligation. Combining survey data on vote-buying with an experiment-based measure...

While economic models have already proven useful to analyze big picture questions about climate policy such as the choice between a carbon tax or cap-and-trade permit system, the 19 chapters in this book show how economic models also are useful to address the many remaining smaller questions...

A new and important concept in global warming economics and policy is the social cost of carbon or SCC. This concept represents the economic cost caused by an additional ton of carbon-dioxide emissions or its equivalent. The present study describes the development of the concept as well as its...

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...

Policy-makers have instituted a variety of fuel economy tax policies -- polices that tax or subsidize new vehicle purchases on the basis of fuel economy performance -- in the hopes of improving fleet fuel economy and reducing gasoline consumption. This article reviews existing policies and...

This paper develops an analytical model to quantify the costs and distributional effects of various fiscal options for allocating the (large) rents created under prospective cap-and-trade programs to reduce domestic, energy-related CO2 emissions. The trade-off between cost effectiveness and...

This paper uses data from the Health and Retirement Study to explore the mechanism that underlies the robust relation found in the literature between cognitive ability, and in particular numeracy, and wealth, income constant. We have a number of findings. First, the more valuable the pension,...

This paper investigates how increases in the level of maximum earnings subject to the Social Security payroll tax have affected Social Security benefits and taxes. The analysis uses data from the Health and Retirement Study to ask how different the present value of own benefits and taxes would...

We develop a theory of optimal unemployment insurance (UI) that accounts for workers’ job-search behavior and firms’ hiring behavior. The optimal replacement rate of UI is the conventional Baily [1978]-Chetty [2006a] rate, which solves the trade-off between insurance and job-search...
