We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality---through climate change---from using fossil energy. A central result of our paper is an analytical derivation of a simple formula for the marginal externality damage of emissions. This formula, which holds...

This paper studies structural transformation of Soviet Russia in 1928-1940 from an agrarian to an industrial economy through the lens of a two-sector neoclassical growth model. We construct a large dataset that covers Soviet Russia during 1928-1940 and Tsarist Russia during 1885-1913. We use a...

In this paper, we consider a dynamic economy in which the agents are privately informed about their skills, which evolve stochastically over time in an arbitrary fashion. We consider an asset pricing equilibrium in which equilibrium quantities are constrained Pareto optimal. Under the assumption...

We assume that individuals can fully insure themselves against cross-country shocks, but not against individual-specific shocks. We consider two particular models of limited risk-sharing: domestically incomplete markets (DI) and private information-Pareto optimal (PIPO) risk-sharing. For each...

We study the interplay of share prices and firm decisions when share prices aggregate and convey noisy information about fundamentals to investors and managers. First, we show that the informational feedback between the firm's share price and its investment decisions leads to a systematic...

With only minimal restrictions on security payoffs and trader preferences, noisy aggregation of heterogeneous information drives a systematic wedge between the impact of fundamentals on the price of a security, and the corresponding impact on cash flow expectations. From an ex ante perspective,...
