　　　　报告摘要：

　　　　I show that the composition of the financial sector has important asset pricing implications beyond the health of the aggregate financial sector. To assess the impact of massive balance sheet adjustments within the intermediary sector during the Great Recession and resolve conflicting asset pricing evidence, I propose a dynamic asset pricing model with heterogeneous intermediaries facing financial frictions. Asset flows between intermediaries are quantitatively important for both the level of and variation in the risk premium. An empirical measure of the composition of the intermediary sector negatively forecasts future excess returns and is priced in the cross-section with a positive price of risk.

　　　　报告摘要：This paper develops methods for constructing asymptotically valid confidence intervals for  the date of a single break in multivariate time series, including I(0), I(1), and deterministically  trending regressors. Although the width of the asymptotic confidence interval does not decrease  as the sample size increases, it is inversely related to the number of series which have a common break date, so there are substantial gains to multivariate inference about break dates. These  methods are applied to two empirical examples: the mean growth rate of output in three European  countries, and the mean growth rate of U.S. consumption, investment, and output.
