Econometric Methodology and Preliminiary FindingsFuture work
Focus on the influence of housing and financial wealth onhealthcare expenditure.
Only few studies have provided empirical evidence on theeffect of wealth on healthcare spending. These includeOkunade, Suraratdecha, and Benson (2010), Marshall,McGarry, and Skinner (2010), and Kim and Ruhm (2012).

Motivation1 Okunade, Suraratdecha, and Benson (2010): the first
study to analyse the effect of wealth (using proxies such as airconditioner, motorbike, car, television etc) on the householdhealthcare expenditure, but they focus on data of Thailand.
2 Marshall, McGarry, and Skinner (2010): use the Healthand Retirement Survey and find that the expenditures arestrongly positively related to wealth but weakly related toincome (near the end of life).
3 Kim and Ruhm (2012): use the Health and RetirementSurvey and inheritances as an instrument for positive wealthshock and find positive and small but insignificant effect ofshocks on the probability of positive expenditures.

Research gap and Contribution1 Previous studies on U.S. focus only on elderly population.
2 Previous studies donot analyze the independent role offinancial and housing wealth, though the literature on wealthand consumption indicates that such effects could exist (e.g.,Bostic, Gabriel, and Painter, 2009; Case, Quigley, and Shiller,2012).
3 Previous studies donot include the most recent data (2010).

Household healthcare expenditure data are obtained fromConsumer Expenditure Survey (BLS)
1 Survey also provides information on demographiccharacteristics and assets and liabilities
2 Healthcare expenditure is the sum of four components: healthinsurance, medical services, prescription drugs, and medicalsupplies
3 Each household is interviewed five consecutive times, once perquarter. Focuses only on the households who completed allfive interviews.
4 Uses the Survey of Consumer Finance (SCF) to impute thewealth data (Bostic, Gabriel, and Painter, 2009). SCF hasrelatively good coverage of wealth data compared to othersurveys conducted in U.S. ( Kennickell and Woodburn, 1999)

Survey of Consumer Finance (SCF) handles missing data problemby employing multiple imputation method. Under this method,SCF provides five different estimates (called implicates) resulting ina total data set with five times the actual number of householdsand hence five different matched datasets. The results providedearlier are only for the first implicate. However, these results areconsistent with the results for other four implicates.

1 The analysis needs to be conducted separately for thecalendar years 2004, 2001, 1998, 1995, 1992, and 1989 andthen for the pooled sample (1989-2010).
2 Examine the robustness of results to using net wealthmeasures (net financial wealth), home equity, and otherresidential real estate equity.
3 Examine whether the credit/liquidity constraints will haveeffect on the households healthcare spending.
4 Use Box Cox hurdle model to take into account non-normalityin health care expenditure.
