Two-country single-good real business cycle models predict that the cr
osscountry correlation of output is smaller than the cross-country cor
relations of consumption and productivity, in contrast to the evidence
in historical samples. The objective of this paper is to reproduce th
e observed empirical evidence in a two-country real business cycle mod
el with endogenous growth. Central features of the model include a non
market sector and international externalities in production. The model
generates realistic cross-country correlations for output, consumptio
n, and productivity with standard parameter values.
