of the history of stock prices from consumption data. It explains the short- and long-run equity premium puzzles despite a low and constant risk-free rate. The results are essentially the same whether we model stocks as a claim to the consumption stream or as a claim to volatile dividends poorly correlated

inter-firm reallocations towards more productive firms. These phenomena have been empirically documented but can not be explained by current general equilibrium trade models, because they rely on a representative firm framework. The paper also shows how the aggregate industry productivity growth

This study investigates whether market-wide liquidity is a state variable important for asset pricing. We find that expected stock returns are related cross-sectionally to the sensitivities of returns to fluctuations in aggregate liquidity. Our monthly liquidity measure, an average of individual

In this paper we study both market risks and non-market risks, without complete markets assumption, and discuss methods of measurement of these risks. We present and justify a set of four desirable properties for measures of risk, and call the measures satisfying these properties "

We present a simple overlapping generations model of an asset market in which irrational noise traders with erroneous stochastic beliefs both affect prices and earn higher expected returns. The unpredictability of noise traders ’ beliefs creates a risk in the price of the asset that deters rational

This paper develops a general framework for analyzing corporate risk management policies. We begin by observing that if external sources of finance are more costly to corporations than internally generated funds, there will typically be a benefit to hedging: hedging adds value to the extent

This paper compares three institutions that offer an elastic currency- open market operations, a discount window, a private, banknote-issuing clearinghouse- in an economy with financial markets otherwise hampered by a lack of liquidity. When this economy is subject to aggregate financial shocks

This paper assesses the long-run optimal level of public debt in a non Ricardian framework with aggregate fluctuations. Households are subject to aggregate and idiosyncratic risk, face borrowing constraints and the incompleteness of markets prevents them from perfectly insuring against risk. We

The authors suggest that the most promising route to effective strategies for the prevention of adolescent alcohol and other drug problems is through a risk-focused approach. This approach requires the identification of risk factors for drug abuse, identification of methods by which risk factors

This paper assesses the optimal level of public debt in a new framework where aggregate fluctuations are taken into account. We find that the optimal level of public debt is higher when fluctuations at the macro level are considered when compared to an economy that leaves them aside. To show
