Health shocks - Labor supply - Income (earned and unearned) - Medical spending Food consumption Non-food consumption - Health insurance - Coping methods: - Saving - Gift - Borrowing/loan - Asset • - Social insurance/security • Informal solidarity Financial risks Consumption insurance
Which kind of insurance can protect welfare loss? • For common minor illnesses vs. • for unanticipated major illnesses • First-dollar coverage with low capped benefits vs. • catastrophic insurance with patient cost-sharing 1 1 Townsend (1995); Kochar (1995) found families in LICs were able to insure illness shocks fairly well.

hij Xij ln(C/n)ij 2.1 2.2 1. Moving from being able to perform all ADLs to being able to perform none would lower consumption by 19.5%
Section V: The extent to which households are able to insure consumption Biased est.: For each Rp. that income falls, consumption falls by only 3% Unbiased est.: For each Rp. that income falls, consumption falls by 35% Households are able to insure only 65% of the consumption with respect to income loss due to a loss in ADL
Instrument Variable (IV) OLS method C = 0 + 0Y + X0 + 0 Consumption: Y is endogenous: some unobserved variables affect both Y and C. Hence, Is biased (change in Y affecting change in C is spurious). IV method Y = 1 + 1h + Z1 + 1 Step 1. Income C = 2 + 2 + X2 + 2 Step 2. Consumption Predicted Y as an instrument

Urban Rural Effects on income per household Regression coefficient and (t-statistics) An urban household’s earned income is more vulnerable to death shocks than an rural household’s. Statistically non-significant An increase in unearned income offsets a decrease in earned income; whereby other-than death shocks in urban area are larger than in rural area. Statistically non-significant
Effects on income per capita Urban Effect of a death on per capita income Is statistically non-significant and is less than on household income. Rural
Effects on medical expenditure (1) Urban Rural
Effects on medical expenditure (2) Insured Uninsured
Urban Rural Effects on food consumption Households cannot smooth their food consumption in the face of some health shocks!
Urban Rural Effects on non-food/non-medical consumption The evidence is more mixed!
