Amphoe or "county" level test within Thailand's five major geographic regions indicate that consumption smoothing across households (risk-sharing that is) is good for farmers in the North and Northeast, but less significant for entrepreneurs or farmers whose primary crop is rice, and less significant for all other occupations in other regions of the country. The results are consistent with the hypothesis that the effectiveness of mechanisms for sharing of risk may diminish as a country grows, with effectiveness lower in regions with high levels and higher growth rates of income.
