Corporate Saving in Global Rebalancing
In this paper, we examine theoretically how corporate saving in emerging markets is contributing to global rebalancing. We consider a two-country dynamic general equilibrium model, based on Bacchetta and Benhima (2014), with a Developed and an Emerging country. Firms need to save in liquid assets to finance their production projects, especially in the Emerging country. In this context, we examine the impact of a credit crunch in the Developed country and of a growth slowdown in both countries. These three shocks imply smaller global imbalances and a positive output comovement, but have a different impact on interest rates. Contrary to common wisdom, a slowdown in the Emerging market implies a trade balance improvement in the Developed country.
News, Sentiment and Capital Flows
We examine empirically the effect of two types of shocks related to expectations -- "news" (increases in expected future productivity) and "sentiment" (surges in optimism unrelated to future productivity) -- on gross capital flows. These two shocks together explain more than 80% of the variation in gross capital flows at all horizons, with the largest part being due to sentiment shocks. Both shocks drive a positive correlation between gross inflows and outflows but only sentiments shocks generate procyclical gross flows. We show that sentiment shocks are not accounted for by financial, monetary or uncertainty shocks, nor are they purely global. The empirical effect of news and sentiment shocks constitute a challenge to most theories of capital flows, but are consistent with the existence of asymmetric information between domestic and foreign investors about the country's fundamentals.
Safety Traps
Fear of risk provides a rationale for protracted economic downturns. We develop a real business cycle model where investors with decreasing relative risk aversion choose between a risky and a safe technology that exhibit decreasing returns. Because of a feedback effect from the interest rate to risk aversion, two equilibria can emerge: a standard equilibrium and a "safe" one in which investors invest in safer assets. We refer to the dynamics of this second equilibrium as a safety trap because it is self-reinforcing as investors accumulate more wealth and show it to be consistent with Japan's lost decade.
The Demand for Liquid Assets, Corporate Saving, and Global Imbalances
In the recent decade, capital outflows from emerging economies, in the form of a demand for liquid assets, have played a key role in the context of global imbalances. In this paper, we model the demand for liquid assets by firms in a dynamic open-economy macroeconomic model. We find that the implications of this model are very different from standard models, because the demand for foreign bonds is a complement to domestic investment rather than a substitute. We show that this complementarity is at work when an emerging economy is on its convergence path or when it has a higher TFP growth rate. This framework is consistent with global imbalances and with a number of stylized facts such as high corporate saving rates in high-growth, high-investment, emerging countries.
When Do Long-Term Imbalances Lead to Current Account Reversals?
We extend the literature on sharp reductions in current account deficits by taking into account not only short-term determinants, but also the deviation of net foreign assets from their long-run equilibrium level. First, we analyse the long-term relationship between net foreign assets and a set of explanatory variables and construct a measure of imbalances. Next, we model current account reversals by incorporating this new measure and compare the predictive power of this model with the baseline specification that does not account for long-term imbalances. Our new model has a superior performance in and out-of-sample, especially when we control for the sign of imbalances. We also find that low net foreign assets do not necessarily lead to sharp reductions in current account deficits; it is rather the situation when they are below their equilibrium level that triggers reversals. Finally, we document that our new measure of net foreign asset imbalances is important only for developing countries, whereas standard models perform well for industrial economies.
