If agents in workhorse business cycle models with financial frictions are allowed to index contracts to observable aggregates, they share aggregate financial risk (almost) perfectly. Thus, the borrowing-constrained capital holders' wealth share does not collapse following adverse shocks and the...

We study optimal growth under learning. We extend the Mirman-Zilcha stochastic growth results characterizing optimal programs for general utility and production functions to the case of learning. We then use recursive methods to study the effect of learning on the dynamic program by considering...

Households' and firms' subjective inflation expectations play a central role in macroeconomic and intertemporal microeconomic models. We discuss how subjective inflation expectations are measured, the patterns they display, their determinants, and how they shape households' and firms' economic...

We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies...

This paper studies the differences between private and government provision of infrastructure. Capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...

The paper studies the determinants of income distribution and growth in an overlapping generations economy with heterogeneous households. Our framework has the following main features: (1) heterogeneity of consumers with respect to wealth and parental human capital; (2) intergenerational...

We are interested in three related questions: (1) How should accounting prices be estimated? (2) How should we evaluate policy change in an imperfect economy? (3) How can we check whether intergenerational well-being will be sustained along a projected economic programme? We do not presume that...

We introduce learning in a Brock-Mirman environment and study the effect of risk generated by the planner's econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty from the anticipation...
