The 19th century economist, Thomas Robert Malthus, hypothesized that the long-run supply of labor is completely elastic at a fixed wage-income level because population growth tends to outstrip real output growth. Dynamic equilibrium with constant income and population is achieved through...

This paper sketches a theory of the secular decline in morbidity and mortality that takes account of changes in human physiology since 1700. The synergism between technological and physiological improvements has produced a form of human evolution, much more rapid than natural selection, which is...

While output declined in virtually all transition economies in the initial years, the speed and extent of the recovery that followed has varied widely across these countries. The contrast between the more and less successful transitions, the latter largely in the former Soviet Union, raises many...

When Roosevelt abandoned the gold standard in April 1933, he converted what had been effectively real government debt into nominal government debt to open the door to unbacked fiscal expansion. We argue that he followed a state-contingent fiscal rule that ran nominal-debt-financed primary...

It is well known from anecdotal, survey and econometric evidence that the relationship between the exchange rate and macro fundamentals is highly unstable. This could be explained when structural parameters are known and very volatile, neither of which seems plausible. Instead we argue that...

What is good for big business need not generally advance a country's overall economy. Big business turnover correlates with rising income, productivity, and (in high income countries) faster capital accumulation; consistent with Schumpeter's (1912) creative destruction and recent formalizations...

In this paper we investigate the sources of the important shifts in the volatility of U.S. macroeconomic variables in the postwar period. To this end, we propose the estimation of DSGE models allowing for time variation in the volatility of the structural innovations. We apply our estimation...

To American and European economists in 1945, the countries of Asia were unpromising candidates for high economic growth. In 1950 even the most prosperous of these countries had a per capita income less than 25 percent of that of the United States. Between the mid-1960s and the end of the...

This paper surveys much of modern macroeconomics. The focus is on the core macroeconomic issue, of the reasons for macroeconomic fluctuations and sometimes persistent unemployment. To provide continuity and perspective on how promising research leads of the past turned out, the paper starts by...

A recent endogenous growth literature has focused on the transition from a Malthusian world where real wages were linked to factor endowments, to one where modern growth has broken that link. In this paper we present evidence on another, related phenomenon: the dramatic reversal in...
