We offer the first direct evidence of an implicit contract in a goods market. The evidence we offer comes from the market for Coca-Cola. We demonstrate that the Coca-Cola Company left a substantial amount of written evidence of its implicit contract with its consumers—a very explicit form of...

We use U.S. county data (3,058 observations) and 41 conditioning variables to study growth and convergence. Using OLS and 3SLS-IV we report on the full sample and metro, non-metro, and 5 regional samples: (1) OLS yields convergence rates around 2 percent; 3SLS yields 6–8 percent; (2)...

In this paper we outline (i) why sigma-convergence may not accompany beta-convergence, (ii) discuss evidence of beta-convergence in the U.S., and (iii) use U.S. county-level data containing over 3,000 cross-sectional observations to demonstrate that sigma-convergence has not occurred at the...

Measuring labor's share of an economy's aggregate income seems straightforward,at least in principle. Count up wage and salary income, along with the value of benefitsprovided to employees, and divide it by total income. However, one fundamentalconcept of labor's share in macroeconomic theory is...

Julius Caesar and Cornelius Tacitus provide characterizations of early Germanic (barbarian) society around, respectively, 50 BC and 50 AD. The earlier date corresponds to expansion of Rome to the Rhine and Danube. During the subsequent century Germanic governance institutions changed in a number...

We consider a decentralized version of the neoclassical growth model where labor share is chosen by workers to maximize their long run (permanent) wages. In this framework, if the labor share increases relative to the competitive share, workers capture a larger share of a smaller total income in...

We examine a balanced panel of globalization indices for 129 countries over the years 1991-2010. We report evidence of cross-country sigma convergence in the overall globalization index. Sigma convergence also holds for each of the economic, political, and social globalization indices, as well...
