, the Discussion Paper series within each division and the Director General's Office of IFPRI were merged into one IFPRI-wide Discussion Paper series. The new series begins with number 00689, reflecting the prior publication of 688 discussion papers within the dispersed series. The earlier series are available on IFPRI's website at www.ifpri.org/pubs/otherpubs.htm#dp. 2 IFPRI Discussion Papers contain preliminary material and research results. They have not been subject to formal external reviews managed by IFPRI's Publications Review Committee but have been reviewed by at least one internal and/or external reviewer. They are circulated in order to stimulate discussion and critical comment.

This paper estimates attitudes towards risk using data obtained through interviews of 400 households in villages in Indonesia. Participants were invited to play investment games in order to identify household risk attitudes. The game result supports the hypothesis of non-decreasing partial relative risk aversion. Using an ordered probit model, the determinants of risk attitude were investigated. The results show that the variable of co-residence is important: an individual living with his or her parents is less risk averse than an individual in a nuclear household. Co-residence can be viewed as a type of 'security blanket'. Partial relative risk aversion decreases with the level of education and wealth.

This paper analyzes the changes in determinants of inter-provincial income inequality in Indonesia from 1983 to 2004 associated with structural changes using the bi-dimensional decomposition method of a population-weighted coefficient of variation. The method unifies two inequality decompositions by regional groups and GRP components (industrial sectors) and thus enables us to assess the contributions of GRP components to within-region and between-region inequalities, as well as to overall inequality. As the share of mining has decreased, the spatial distribution of manufacturing has played a more important role in the inequality of Sumatra and Kalimantan, while the primacy of Jakarta, with strong urbanization economies, facilitated by globalization and trade and financial liberalization, has determined much of Java-Bali's inequality and, therefore, overall inequality in Indonesia.
