This paper develops an agent-based model of learning process that systematically organizes actual choice behavior along the path to equilibrium. The model relies on expected utility maximization to provide directions for economic agents to make choices at the margin toward their ends in adaptive...

We consider the demand for state contingent claims in the presence of a zero-mean, nonhedgeable background risk. An agent is defined to be generalized risk averse if he/she reacts to an increase in background risk by choosing a demand function for contingent claims with a smaller slope. We show...

This paper tests one specific monetary transmission mechanism through households: portfolio rebalancing. We use a unique panel dataset of household's credit and debit card spending, ATM withdrawals, financial investments into risky assets such as mutual funds and equities, as well as bank...

This paper explores the optimal consumption and investment behavior of an individual who derives utility from the ratio between his consumption and an endogenous habit. We obtain closed-form policies under general utility functionals and stochastic investment opportunities, by developing a...

I revisit the question of which motive underlies insurance demand. I draw on the literature of state-dependent utility and on the literature of imperfectly divisible consumption to argue that the general purpose of insurance is not a risk transfer, but meeting a conditional need. In this way,...

We study interest rates transmission to savings at low and negative rates. Exploiting cohorts of consumers from a data-rich multi-country survey, we show how the strength of interest rate transmission to savings varies with the level of nominal interest rates. This response is positive when...

Deriving an optimal asset allocation for institutional investors hinges crucially on the quality of inputs used in the optimization. If the mean vector and the covariance matrix are known with certainty, the classical mean-variance optimization of Markowitz (1952) produces optimal portfolios....

We estimate risk aversion from investors' financial decisions in a person-to-person lending platform. We develop a method that obtains a risk aversion parameter from each portfolio choice. Since the same individuals invest repeatedly, we construct a panel dataset that we use to disentangle...

Existing studies of household stock trading using administrative data offer conflicting results: Discount brokerage accounts exhibit excessive trading, while retirement accounts show inactivity. This paper uses population-wide data from PSID and SCF to examine the overall extent of household...
