When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations and demonstrate that they interact over the life-cycle. The interactions appear even though...

We study the impact of diverse beliefs on conduct of monetary policy. We use a New Keynesian Model solved with a quadratic approximation. Aggregation renders the belief distribution an aggregate state variable. Diverse expectations change standard results about a smooth trade-off between...

The collapse of an investment mania usually reminds people that the phrase "This time is different" is dangerous. Recollections of this mantra then typically either state outright or at least imply that "It is never different." However, there is at least one counterexample to this cautious view,...

Three shocks, distinguished by whether their effects are permanent or transitory, are identified to characterize the post-war dynamics of aggregate consumer spending, labor earnings, and household wealth. The first shock accounts for virtually all of the variation in consumption and has effects...

We show that there is strong commonality in the volatility of a wide range of diversified equity portfolios. Common factor volatility (CFV) exists even when factor or anomaly returns are market-adjusted and does not appear to be attributable to common microstructure noise or a lack of...

Libor is arguably the world's most important number with more than USD 350 trillion of loans and financial contracts referencing this rate. Libor benchmark interest rates are being replaced with alternative reference rates (ARRs). There is no guarantee Libor rates will continue to be quoted...

Why do risk premia vary over time? We examine this problem theoretically and empirically by studying the effect of market belief on risk premia. Individual belief is taken as a fundamental state variables. Market belief is observable, it is central to the empirical evaluation and we show how to...

This paper investigates the impact of agents' expectations about future fundamental economic disturbances (news) on macroeconomic dynamics. Several intuitive tests provide insight into the information content of the yield curve and its' ability to identify these 'news' disturbances. Bayesian...
