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...

Prior to the famous One Child Policy, China's total fertility rate declined by more than 50% during the 1970s - one of the most rapid sustained fertility declines documented in modern history. Coinciding with this transition was China's first national population policy, Wan Xi Shao, also known...

We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions accounting for the fact that...

This paper investigates how fertility responds to changes in the price of a marginal child and in household income. We construct a large, individual-level panel data set of married Israeli women during the period 1999-2005 that contains fertility histories and detailed controls. We exploit...

Is there an economic rationale for pronatalist policies? In this paper we propose and analyze a particular market failure that may lead to inefficiently low equilibrium fertility and therefore to a need for government intervention. The friction we investigate is related to the ownership of...

There is longstanding debate in population policy about the relationship between modern contraception and abortion. Although theory predicts that they should be substitutes, the existing body of empirical evidence is difficult to interpret. What is required is a large-scale intervention that...

This paper studies the effect that changing demographic patterns have had on the household saving rate in China. We undertake a quantitative investigation using an overlapping generations (OLG) model where agents live for 85 years. Consumers begin to exercise decision making when they are 18....

The share of the population aged 60 and over is projected to increase in nearly every country in the world during 2005-2050. Population ageing will tend to lower both labor-force participation and savings rates, thereby raising concerns about a future slowing of economic growth. Our calculations...

We develop a consistent and comprehensive theoretical framework for assessing whether economic growth is compatible with sustaining well-being over time. The framework focuses on whether a comprehensive measure of wealth - one that accounts for natural capital and human capital as well as...

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...
