Can variations in the expected future return on a portfolio of sovereign bonds itself have real effects on a small open economy? We build a model where banks face a capital sufficiency requirement to demonstrate that news about a fall in the expected return on a portfolio of long bonds can lead...

An emerging view of business cycles from the news-shock literature suggests that recessions may occur when agents depress their demand for new capital upon the realization that they have accumulated too much conditional on current information. In this paper I use a New Keynesian model with a...

The boom-years preceding the "Great Recession" were a time of rapid innovation in the financial industry. We explore the idea that both the boom and eventual bust emerged from overoptimistic ex-pectations of efficiency-gains in the financial sector. We treat the bankruptcy costs facing...

What is the effect of the fear of future sovereign default on the economy of the defaulting country? The typical sovereign default model does not address this question. In this paper we wish to explore the possibility that changing expectations about future default themselves can lead to...

We pursue a novel empirical strategy to identify monetary news shocks and determine their effects on the US economy during the Greenspan-Bernanke era of Federal Reserve Chairmanship. We first construct a monetary policy residual as gap between the observed federal funds rate and a policy rule....

The news-shock literature interprets empirical news-shock identifications as signals about future productivity. Under this view, changes in productivity cause changes in expectations. I investigate an alternative interpretation whereby changes in expectations cause changes in productivity. I...

We explore the ability of a model with knowledge capital to generate business cycles driven by expectations of future movement in total factor productivity (TFP). These cycles are characterized by a boom in which consumption, investment, output and hours-worked all rise in advance of any actual...

The years leading up to the "great recession" were a time of rapid innovation in the financial industry. This period also saw a fall in credit spreads and a boom in liquidity and asset prices that accompanied the boom in real activity, especially investment. In this paper we argue that these...

What is the effect of the fear of future sovereign default on the economy of the defaulting country? The typical sovereign default model does not address this question. In this paper we wish to explore the possibility that changing expectations about future default themselves can lead to...

I present a theoretical model where the economy endogenously adopts the technological ideas of a slowly evolving technological frontier, and show that the presence of a "technological gap" between unadopted ideas and current productivity can lead to multiple equilibria and therefore the...
