We present a model of efficient regulation along the lines of Demsetz (1967). In this model, setting up and running regulatory institutions takes a fixed cost, and therefore jurisdictions with larger populations affected by a given regulation are more likely to have them. Consistent with the...

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...

In this paper, we generalize the notion of Pareto-efficiency to make it applicable to environments with endogenous populations. Two efficiency concepts are proposed, P-efficiency and A-efficiency. The two concepts differ in how they treat people who are not born. We show how these concepts...

One of the economic benefits of immigration is that the diversity of the population is enhanced. Diversity, it is argued, enriches the environment in which individuals live and trade and may contribute to greater creativity. What does diversity mean? Do current immigration policies enhance...

Fertility change is distinct from other forms of social and economic change because it directly alters the size and composition of the next generation. This paper studies how changes in population composition over the fertility transition feed back into the evolution of average fertility across...

Despite being key to theories of economic growth and the demographic transition, evidence on how fertility responds to aggregate income change is mixed. We analyze economic growth and fertility change in the developing world over six decades, using data on 2.3 million women from 255 surveys in...

In this short note I simulate the DR under various conditions and make comparisons with the US. Japan has experienced a large increase in its DR because its fertility rate is low, its people are long lived and it has little immigration. Fertility is the largest of the contributors in Japan. If...

I argue in this paper for more interaction between economic history and economic development. Both subfields study economic development; the difference is that economic history focuses on high-wage countries while economic development focuses on low-wage economies. My argument is based on recent...

A stylized fact of modern growth is that as countries become richer, education levels rise while family size decreases. This paper provides evidence that well before the onset of modern growth, changes in the return to education affected household choice of children's quantity versus quality....
