We develop a tractable asset-pricing framework characterized by imperfect risk sharing among cohorts, who experience different levels of integrated life-time endowments. While all asset-pricing implications stem from the heterogeneity of consumption among investors, cross-sectional measures of...

We study asset-pricing implications of innovation in a general-equilibrium overlapping-generations economy. Innovation increases the competitive pressure on existing firms and workers, reducing the profits of existing firms and eroding the human capital of older workers. Due to the lack of...

In this paper we study the implications of general-purpose technological growth for asset prices. The model features two types of shocks: "small", frequent, and disembodied shocks to productivity and "large" technological innovations, which are embodied into new vintages of the capital stock....

We propose a tractable model of an informationally inefficient market featuring non-revealing prices, no noise traders, and general assumptions on preferences and payoff distributions. We show the equivalence between our model and a substantially simpler model whereby investors face...

We propose a unified model of limited market integration, asset-price determination, leveraging, and contagion. Investors and firms are located on a circle, and access to markets involves participation costs that increase with distance. Despite the ex-ante symmetry of investors, their strategies...
