Social policy to limit interactions can slow the spread of infection, but this benefit comes at the cost of reduced output. We solve an optimal control problem to choose the degree of interaction to maximize an objective function that rewards output and penalizes excess deaths. Optimal policy...

A financial constraint that prevents access to external funds induces non-classical measurement error in average q as a proxy for unobservable marginal q. Unlike classical measurement error, this measurement error biases upward the coefficient on average q in a univariate regression of...

Recurrent intervals of inattention to the stock market are optimal if consumers incur a utility cost to observe asset values. When consumers observe the value of their wealth, they decide whether to transfer funds between a transactions account from which consumption must be financed and an...

Government debt can be rolled over forever without primary surpluses in some stochastic economies, including some economies that are dynamically efficient. In an overlapping-generations model with constant growth rate, g, of labor-augmenting productivity, and with shocks to the durability of...
