The consumption growth data strongly favor a two-regime specification. The high volatility, low growth regime is associated with deep recessions: the Great Depression, the recession of 1937-1938, the post-war recession of 1945, and the most recent financial crisis. I develop parsimonious models in which (i) consumption and dividend growth follow regime-switching dynamics, (ii) the regime characteristics are consistent with the empirical evidence from the consumption growth data, and (iii) the risks associated with regime shifts are priced in asset markets. The models explain major regime-dependent asset market phenomena. Regime-shift risk exhibits the dominant influence on asset prices: It generates a high equity premium, and also induces time-varying risk premiums and explains the return predictability.

We examine various dynamic term structure models for monthly US Treasury yields from 1964 to 2001. Of particular interest is the predictability of bond excess returns. Recent evidence indicates that using multiple forward rates can sharply predict future excess returns on bonds; the R2 of this predictability regression can be as high as 30%. In addition, the projection coefficients in these predictability regressions exhibit a tent shaped pattern that relates to the maturity of the forward rate. This dimension of the data in conjunction with the transition dynamics of bond yields (i.e., conditional volatility and cross-correlation of bond yields) poses an serious challenge to term structure models. In this paper we present and estimate a regime-shifts term structure model - our findings show that this model can account for all aspects of the predictability regression and the transition dynamics of yields. Alternative models, such as, affine factor models cannot account for these features of the data. We find that the regimes in the model are related to the NBER business cycle indicator.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Risk and Business Cycles examines the causes of business cycles, a perennial topic of interest within economics. The author argues the case for the revival of an important role for monetary causes in business cycle theory, which challenges the current trend towards favouring purely real theories. The work also presents a critique of the traditional Austrian theory of the trade cycle. This controversial approach will ensure that the book is of interest to all those involved with business cycles, as well as Austrian economics.
