Macroeconomic regimes

A New-Keynesian macro-model is estimated accommodating regime-switching behavior in monetary policy and macro-shocks. A key to our estimation strategy is the use of survey-based expectations for inflation and output. Output and inflation shocks shift to the low volatility regime around 1985 and 1990, respectively. Monetary policy experiences multiple shifts with an important role in shaping macro-volatility. New estimates of the onset and demise of the Great Moderation are provided and the relative role played by macro-shocks and monetary policy is quantified. The estimated rational expectations model exhibits indeterminacy in the mean-square stability sense, mainly due to passive monetary policy

The Determinants of Stock and Bond Return Comovements

We study the economic sources of stock-bond return comovements and its time variation using a dynamic factor model. We identify the economic factors employing a semi-structural regime-switching model for state variables such as interest rates, inflation, the output gap, and cash flow growth. We also view risk aversion, uncertainty about inflation and output, and liquidity proxies as additional potential factors. We find that macro-economic fundamentals contribute little to explaining stock and bond return correlations, but that other factors, especially liquidity proxies, play a more important role. The macro factors are still important in fitting bond return volatility; whereas the "variance premium" is critical in explaining stock return volatility. However, the factor model primarily fails in fitting covariances.

Macroeconomic Regimes

We estimate a New-Keynesian macro model accommodating regime-switching behavior in monetary policy and in macro shocks. Key to our estimation strategy is the use of survey-based expectations for inflation and output. We identify accommodating monetary policy before 1980, with activist monetary policy prevailing most but not 100% of the time thereafter. Systematic monetary policy switched to the activist regime in the 2000-2005 period through an aggressive lowering of interest rates. Discretionary policy spells became less frequent since 1985, but the Volcker period is identified as a discretionary period. Output shocks shift to the low volatility regime around 1985 whereas inflation shocks do so only around 1990, suggesting active monetary policy may have played role in anchoring inflation expectations. Shocks and policy regimes jointly drive the volatility of the macro variables. We provide new estimates of the onset and demise of the Great Moderation and the relative role played by macro-shocks and monetary policy.

The estimated rational expectations model exhibits indeterminacy in the mean square stability sense, mainly because monetary policy is excessively passive

The determinants of stock and bond return comovements

We study the economic sources of stock-bond return comovement and its time variation using a dynamic factor model. We identify the economic factors employing structural and non-structural vector autoregressive models for economic state variables such as interest rates, (expected) inflation, output growth and dividend payouts. We also view risk aversion, and uncertainty about inflation and output as additional potential factors. Even the best-fitting economic factor model fits the dynamics of stock-bond return correlations poorly. Alternative factors, such as liquidity proxies, help explain the residual correlations not explained by the economic models

Flights to safety

Despite a large and growing theoretical literature on flights to safety, there does not appear to exist an empirical characterization of flight-to-safety (FTS) episodes. Using only data on bond and stock returns, we identify and characterize flight to safety episodes for 23 countries. On average, FTS days comprise less than 5% of the sample, and bond returns exceed equity returns by 2 to 3%. The majority of FTS events are country-specific not global. FTS episodes coincide with increases in the VIX, decreases in consumer sentiment indicators and appreciations of the Yen, Swiss franc, and US dollar. The financial, basic materials and industrial industries under-perform in FTS episodes, but the telecom industry outperforms. Money market instruments, corporate bonds, and commodity prices (with the exception of metals, including gold) face abnormal negative returns in FTS episodes. Liquidity deteriorates on FTS days both in the bond and equity markets. Both economic growth and inflation decline right after and up to a year following a FTS spell

Flights to safety

We identify flight-to-safety (FTS) days for twenty-three countries using only stock and bond returns and a model averaging approach. FTS days comprise less than 2% of the sample and are associated with a 2.7% average bond-equity return differential and significant flows out of equity funds and into government bond and money market funds. FTS represents flights to both quality and liquidity in international equity markets, but mainly a flight to quality in the U.S. corporate bond market. Emerging markets, endowment funds, and hedge funds perform poorly during FTS, whereas hedge funds appear to vary their systematic exposures prior to an FTS
