August 2017Household Finance in China
with Russell Cooper: w23741
This paper studies household finance in China, focusing on the high savings rate, the low participation rate in the stock market, and the low stock share in household portfolios. These salient features are studied in a lifecycle model in which households receive both income and medical expense shocks and decide on stock market participation and portfolio adjustment. The structural estimation explicitly takes into account important regime changes in China, such as the re-opening of the stock market, the privatization of the housing market and the labor market reforms that changed household income processes. The paper also compares household finance patterns in China to those in the US, and shows that between-country differences in financial choices are driven by both institutional factors (...
November 2014Household Finance over the Life-Cycle: What does Education Contribute?
with Russell Cooper: w20684
This paper studies household financial choices: why are these decisions dependent on the education level of the household? A life-cycle model is constructed to understand a rich set of facts about decisions of households with different levels of educational attainment regarding stock market participation, the stock share in wealth, the stock adjustment rate and the wealth-income ratio. Model parameters, including preferences, the cost of stock market participation and portfolio adjustment costs, are estimated to match the financial decisions of different education groups. Based on the estimated model, education affects household finance mainly through increased average income. The estimation also finds evidence that higher educational attainment is associated with a lower stock market en...

September 2013Household Finance: Education, Permanent Income and Portfolio Choice
with Russell Cooper: w19455
This paper studies household financial choices: why are these decisions dependent on the education level of the household? A life cycle model is constructed to understand a rich set of facts about decisions of households with different levels of education attainment regarding stock market participation, the stock share in wealth, the stock adjustment rate and wealth-income ratio. Model parameters, including preferences, the cost of stock market participation and portfolio adjustment costs, are estimated to match the financial decisions of different education groups. Based on the estimated model, education matters through two channels: the mean of income and the discount factor.
April 2011Consumption Smoothing and Portfolio Rebalancing: The Effects of Adjustment Costs
with Yosef Bonaparte, Russell Cooper: w16957
This paper studies the dynamics of portfolio rebalancing and consumption smoothing in the presence of non-convex portfolio adjustment costs. The goal is to understand a household's response to income and return shocks. The model includes the choice of two assets: one riskless without adjustment costs and a second risky asset with adjustment costs. With these multiple assets, a household can buffer some income fluctuations through the asset without adjustment costs and engage in costly portfolio rebalancing less frequently. We estimate both preference parameters and portfolio adjustment costs. The estimates are used for evaluating consumption smoothing and portfolio adjustment in the face of income and return shocks.
