This paper extends recent developments in general-equilibrium theory and applies them to the problem of measuring the real output of an economy's insurance sector. These developments permit a priced commodity to be a complex incentive-compatible contract. These contracts are not bundles of more...

We study the aggregate implications of (S, s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S, s) inventory policies are optimal because of fixed order costs. The distribution of...

Does capital-embodied technological change play an important role in shaping labour-market outcomes? To address this question, we develop a model with vintage capital and search-matching frictions where irreversible investment in new vintages of capital creates heterogeneity in productivity...

We derive the quantitative implications of growth theory for U.S. corporate equity plus net debt over the period 1960-2001. There were large secular movements in corporate equity values relative to GDP, with dramatic declines in the 1970's and dramatic increases starting in the 1980's and...
