In this paper, we investigate the relationship between public capital spending and population dynamics at the state level. Empirically, we document two robust facts. First, states with faster population growth do not spend more (per capita) to accommodate the needs of their growing population....

For generations of scholars and observers, the "transportation revolution," especially the railroad, has loomed large as a dominant factor in the settlement and development of the United States in the nineteenth century. There has, however, been considerable debate as to whether transportation...

Debt neutrality is said to occur if, given a program for public spending on current goods and services over time, the real equilibrium of the economy (private consumption, investment, relative prices, etc.) is independent of the pattern of government borrowing and lump-sum taxation over time....

In traditional societies it is often argued that parents' desire for old age security in the form of transfers from their children provides an important motive for childbearing. Some doubt has been cast on this "old age security hypothesis" by recent estimates which suggest that the rate of...

Population growth has declined markedly in almost all major economies since the 1970s. We argue this trend has important consequences for the process of firm dynamics and aggregate growth. We study a rich semi-endogenous growth model of firm dynamics, and show analytically that a decline in...

We develop a novel method for assessing the effect of constraints imposed by spatially-fixed natural resources on aggregate economic output. We apply it to estimate and compare the projected effects of climate change and population growth over the course of the 21st century, by country and...

We assess the evidence on the contribution of changes in the population age structure to the changing fortunes of youths in labor markets in advanced economies over the 1970s, 1980s and early 1990s, and use this evidence to project the likely effects of future cohort sizes on youth labor...

This paper reviews and analyzes forecasts of the Social Security trust funds, government spending, medical expenditures, and other elements of aggregate income and spending. According to these forecasts, the aging of the U.S. population will require some increases in taxes to support the...

Using a highly stylized dynamic microsimulation model, we project the labor force of the United States up to the year 2060 and contrast these projections with projections for Germany to assess differential effects on outcomes The projections are consistent with the U S Census Bureau's and...
