We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complement the results with a measure based on optimal portfolio choice. Among households with relatives living in the same village, full insurance cannot be rejected, suggesting that...

Fully implemented in Thailand in 2002, the Universal Health Care Coverage (UC) Program aimed to provide cheap access to health care services, for 30 baht (less than 1 U.S. dollar) per visit, to all uninsured Thais. In this paper, we studied the impact of the UC in Thailand on the demand for...

Return on assets (ROA) of household enterprise is crucial for understanding the productivity of households in developing economies. Yet the definition and measurement of household enterprise ROA remain inconsistent or unclear. We illustrate potential measurement problems with examples from...

We present a framework for the study of risk and return of household enterprise in developing economies. We make predictions from two polar benchmarks: (1) an economy with Pareto optimal allocations under full risk sharing, and (2) an economy in which each autarky household absorbs risk in...

We present a vision for improving household financial surveys by integrating responses from questionnaires more completely with financial statements and combining them with payments data from diaries. Integrated household financial accounts - balance sheet, income statement, and statement of...

In village economies, insurance networks are key to smoothing shocks, while production networks can propagate them. The interplay of these networks is crucial. We show that a significant health expenditure shock to one household propagates to other linked households via supply-chain and labor...

Despite the considerable attention paid to the theory of tax incidence, there are surprisingly few estimates of the pass-through rate of sales taxes on retail prices. This paper estimates the effect of a suspension and subsequent reinstatement of the gasoline sales tax in Illinois and Indiana on...

Some gasoline markets exhibit remarkable price cycles, where price spikes are followed by a series of small price declines: a pattern consistent with a model of Edgeworth cycles described by Maskin and Tirole. We extend the model and empirically test its predictions with a new dataset of daily...
