This paper uses a unique panel dataset of consumer financial transactions to study how consumers respond to an exogenous unanticipated income shock. Consumption rose significantly after the fiscal policy announcement: during the ten subsequent months, for each $1 received, consumers on average spent $0.80. We find a strong announcement effect—19 percent of the response occurs during the first two-month announcement period via credit cards. Subsequently, consumers switched to debit cards after disbursement before finally increasing spending on credit cards in the later months. Consumers with low liquid assets or with low credit card limit experienced stronger consumption responses.

It is well established that consumption is “hump” shaped over an individual's lifecycle, peaking in middle age and then declining in the years that follow. Prior research has documented that consumption declines at retirement, which is inconsistent with the standard lifecycle model with consumption smoothing. Using a unique dataset with detailed administrative records of credit and debit card transactions, we show the hump shaped lifecycle consumption pattern as documented in the literature. Additionally, we show compositional changes in consumption expenditures across individuals in the years surrounding retirement confirming the results of Aguiar and Hurst (2005, 2013).

Immediately following a minimum wage hike, household income rises on average by about $250 per quarter and spending by roughly $700 per quarter for households with minimum wage workers. Most of the spending response is caused by a small number of households who purchase vehicles. Furthermore, we find that the high spending levels are financed through increases in collateralized debt. Our results are consistent with a model where households can borrow against durables and face costs of adjusting their durables stock.

We study the participation of women in golf, a predominately male social activity, and its influence on their likelihood of serving on a board of directors. Exploiting a novel dataset of all golfers in Singapore, we find that woman golfers enjoy a 54% higher likelihood of serving on a board relative to male golfers. A woman's probability of serving on the board in a large firm or in a predominately male industry increases by 117% to 125% when she plays golf. Joining the boy's informal network appears to facilitate women's entrance or success in the executive labor market.
