AbstractIndivisible labour is not the only type of non‐convexity affecting labour supply decisions. Another type of non‐convexity arises in economies with sectors whenever individuals can work in only one sector at a time. I introduce this restriction into an open economy model with a tradeable and a non‐tradeable sector, and I use lotteries to convexify the consumption possibilities set. This approach implies that the aggregate elasticity of labour supply becomes infinite. I compare the performance of the model with an analogous model in which the labour supply elasticity is finite. I find that there is a disconnect between the response of wages to monetary shocks and the open economy variables. The labour supply elasticity plays a more important role in the transmission of technology and government expenditure shocks to the real exchange rate and the terms of trade.

AbstractWe introduce equilibrium indeterminacy into a two‐country incomplete asset model with imperfect competition to analyze the role of self‐fulfilling expectations or beliefs in explaining international business cycles. We find that, when self‐fulfilling beliefs are correlated with technology shocks, the model can account for the countercyclical behaviour observed for the terms of trade and real net exports while simultaneously generating higher volatilities relative to output, as in the data. The choice of the labour‐supply elasticity is shown to be critical for generating a negative correlation between the real exchange rate and relative consumption, thereby resolving the Backus–Smith puzzle.
