We study a general static noisy rational expectations model, where investors have private information about asset payoffs, with common and private components, and about their own exposure to an aggregate risk factor, and derive conditions for existence and uniqueness (or multiplicity) of...

Agents forming adaptive expectations generally make systematic mistakes. This characterization has fostered the rejection of adaptive expectations in macroeconomics. Experimental evidence, however, shows that in complex environments human subjects frequently rely on adaptive heuristics –...

The adaptive learning approach has been fruitfully employed to model the formation of aggregate expectations at the macroeconomic level, as an alternative to rational expectations. This paper uses adaptive learning to understand, instead, the formation of expectations at the micro-level, by...

The path breaking work of Card and Krueger (1993), showing higher minimum wage can increase employment turned the age-old conventional wisdom on its head. This paper demonstrates that this apparently paradoxical result is perfectly plausible in a competitive general equilibrium production...

Industrial activity periodically experiences breakthrough innovations in energy efficiency, but the estimated impacts of these innovations on aggregate energy use are highly varied. We develop a general equilibrium model to investigate whether this variation is determined by the structure of the...

This paper studies the impact of optimism on occupational choice using a general equilibrium framework. The model shows that optimism has four main qualitative effects: it leads to a misallocation of talent, drives up input prices, raises the number of entrepreneurs, and makes entrepreneurs...

The Atkinson-Stiglitz theorem on uniform consumption taxation breaks down if prices are endogenous. This paper investigates the implications for optimal food subsidies in China. To do so, we build a general equilibrium model where low-skilled workers have a comparative advantage in the...

The growth of for-profit colleges has been historically aided by online instruction, and budget crunches at public institutions, circumstances which have resurfaced during the COVID-19 pandemic. We set up and calibrate a general equilibrium model of competition between public and for-profit...
