<title>Abstract</title> Hydrogen is often seen as a promising future energy carrier given the major reliance of today's transport sector on finite fossil fuels. This article assesses the macroeconomic effects of introducing hydrogen as fuel in passenger transport within the framework of the computable general...

We simulate corporate tax reform in a single good, five-region (U.S., Europe, Japan, China, India) model, featuring skilled and unskilled labor, detailed region-specific demographics and fiscal policies. Eliminating the model's U.S. corporate income tax produces rapid and dramatic increases in...

This paper develops a dynamic, life-cycle, general equilibrium model to study the interdependent demographic, fiscal, and economic transition paths of China, Japan, the U.S., and the EU. Each of these countries/regions is entering a period of rapid and significant aging requiring major fiscal...

This paper and its companion study, Fehr, Jokisch, and Kotlikoff (2004), develop a three-region dynamic general equilibrium life-cycle model to analyze general and skill-specific immigration policy during the demographic transition. The three regions are the U.S., Japan, and the EU. Immigration...

America's aging coupled with high and growing old age health and pension benefits augers for much higher payroll taxes, with potentially damaging effects on the U.S. economy. This prognosis is supported by our analysis of a detailed dynamic life-cycle general equilibrium model, which closely...

The world's leading economies, both developed and developing, are engaged in an ever-changing economic symbiosis that is governed in large part by demographics and technological change, but also by pension, healthcare, and other fiscal policies. This interconnected economic evolution--what...

This chapter examines the micro- and macroeconomic effects of generational policies using closed and open general equilibrium dynamic life-cycle models. The models illustrate the broad array of demographic, economic, and policy issues that can be simultaneously incorporated within todays...
