This paper develops a two-country monetary DSGE model in which households choose a portfolio of home and foreign equities, and a forward position in foreign exchange. Some goods prices are set without full information of the state. We show that temporarily sticky nominal goods prices can have large effects on equity portfolios. Home and foreign portfolios are not identical in equilibrium. In response to technology shocks, sticky prices generate a negative correlation between labor income and the profits of domestic firms, biasing portfolios in favor of home equities. In contrast, under flexible prices, labor income and the profits of the domestic firms are positively correlated. Even a small amount of nominal price stickiness can generate these portfolio differences, depending on the diversification role played by the terms of trade. Returns on human capital and equities may be positively correlated under sticky prices when the source of shocks is monetary, but this risk is hedged through nominal assets rather than through equities.

Abstract.  Though financial globalization should improve international risk sharing, empirical support is lacking. We develop a simple welfare‐based measure that captures how far countries are from the ideal of perfect risk sharing. Applying it to data, we find some evidence that international risk sharing has improved during globalization. Improved risk sharing comes mostly from the convergence in rates of consumption growth among countries rather than from synchronization of consumption at the business cycle frequency.

What is global liquidity and how does it affect an economy? The paper addresses that question by looking at liquidity from two different perspectives: global liquidity as availability of funds in safe and risky asset markets. This distinction between safe and risky asset markets is important due to market segmentation, which called for unconventional monetary policy to restore a function of risky asset markets. To analyze the effect of global liquidity, I construct proxy variables and then asses how they affect an emerging economy whose interest rate is affected by a world risk-free rate and a risk premium. Using the data from four major Latin American countries, I find that these two aspects of global liquidity have similar effects on economic performance in emerging market economies except for their effect on inflation.

This Working Paper should not be reported as representing the views of the IMF.The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. This paper analyzes the role of nonseparable utility and nontradables in business cycles and portfolio choice. I find that nonseparability in utility can change the portfolio choice significantly. Unlike previous results in literature, the optimal portfolio of the traded-good sector equities is no longer a well diversified portfolio and becomes sensitive to parameter values. As a result, the model often generates extreme home bias or anti-home bias portfolios implying that some frictions in asset markets, which prevent agents from holding these extreme portfolios, can explain the lack of international risk sharing.
