Using a proprietary dataset of the portfolio holdings of millions of US households, we document how agents who believe in different models of the world update their beliefs heterogeneously in response to a public signal. We identify households ex ante that hold different models of the world...

Using proprietary portfolio data on millions of households, we show that (likely) Republicans increase the equity share and market beta of their portfolios following the 2016 presidential election, while (likely) Democrats rebalance into safe assets. We provide evidence that this behavior is...

In data from an account aggregator, households increase consumption when they receive (expected) tax refunds, as if they are liquidity constrained. However, this behavior is not due to liquidity constraints or hand-to-mouth behavior. These same households smooth consumption when making payments...

This paper employs a synthetic cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of...

We develop a machine-learning solution algorithm to solve for optimal portfolio choice in a detailed and quantitatively-accurate lifecycle model that includes many features of reality modelled only separately in previous work. We use the quantitative model to evaluate the consumption-equivalent...

We develop a tractable dynamic model of credit markets in which lending standards and the quality of potential borrowers are endogenous. Competitive banks privately choose their lending standards: whether to pay a cost to screen out some unprofitable borrowers. Lending standards have negative...

Tracking the movement of top managers across firms, we document the importance of manager-specific fixed effects in explaining heterogeneity in firm exposures to systematic risk. These differences in systematic risk are partially explained by managers' corporate strategies, such as their...

We examine how third party ratings and mandatory benchmark disclosure affect aggregate risk adjustment by retail investors. Morningstar changed its ratings methodology in June 2002. Before the change, the ratings were based on a risk-adjusted performance ranking of all US equity funds and highly...

Two types of intervention are commonly implemented in networks: characteristic intervention which influences individuals' intrinsic incentives, and structural intervention which targets at the social links among individuals. In this paper we provide a general framework to evaluate the distinct...

The present paper assesses the interactions between innovation and economic institutions within the context of the inequality-growth nexus. By carrying out fixed effects estimations on a cross-country panel, we find that both institutional quality and innovations improve economic growth at the...
