Investment composition and international business cycles
This paper studies a two country model with economies disaggregated into traded and nontraded sectors and in which investment goods as in practice are produced by combining inputs from all sectors. The model also accounts for nontraded distribution services employed in retailing traded goods to consumers. The results show that the model with multiple input investments outperforms the standard model in which sectoral output also serves as its capital. In particular, it substantially improves (a) the movements of trade balance and relative prices, (b) within country comovements of sectoral and aggregate quantities, and (c) cross-country comovements of output vis-à-vis consumption.
