We propose an extension of standard asymmetric volatility models in the generalized autoregressive conditional heteroskedasticity (GARCH) class that admits conditional non-Gaussianities in a tractable fashion. Our “bad environment–good environment” (BEGE) model utilizes two...

We show that the newly developed exchange-traded world equity index funds, or iShares, trade at economically significant premiums for 10–50% of the times even after controlling for transaction costs and time-zone measurement errors. Moreover, iShares price returns exhibit excessive volatility...

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. Output and inflation shocks shift to the low volatility regime around 1985 and...

We identify the relative importance of changes in the conditional variance of fundamentals (which we call uncertainty) and changes in risk aversion in the determination of the term structure, equity prices and risk premiums. Theoretically, we introduce persistent time-varying uncertainty about...
