The body of literature on vulnerability is growing. We classify studies on the concepts and measurements of vulnerability to poverty into welfarist, expected poverty, and axiomatic approaches. Empirical studies on vulnerability to poverty in Asia and elsewhere show that poverty and vulnerability...

We investigate how childbirth affects intrahousehold resource allocation for married Japanese couples. We develop reduced-form and structural-form specifications from a unified theoretical framework. Under a weak set of assumptions, we can focus on private goods to track the changes in...

Health and wealth are found positively correlated, but whether the spatial inequality in health and wealth necessarily exhibits a similar pattern is unclear. We apply the small-area estimation technique to the estimation of inequality in consumption poverty and undernutrition. We develop a...

We propose a method to decompose the logarithmic change of the Divisia price index into the pure price effect, the preference effect and the substitution effect. Our empirical results in the Philippines shows the effects of preference change on the Divisia price index are heterogeneous but...

We study the impact of international remittances on schooling in the Philippines. Unlike the previous studies, we allow for the potential heterogeneity in the impact across households due to the school-age child's relationship to the head of household. This is potentially important, because the...

We consider a simple two-period model with irreversible investment with strategic interactions. In this setup, we try to extend the concept of the quasi-option value (QOV) by Arrow and Fisher (1974), Henry (1974), Fisher and Hanemann (1987) and Hanemann (1989) to a game-theoretic situation. In...

Trade policies can promote aggregate efficiency, but the ensuing structural adjustments generally create both winners and losers. From an incomes perspective, trade liberalization can raise GDP per capita, but rates of emergence from poverty depend upon individual household characteristics of...

We compare two methods of commune-level poverty rankings in Cambodia, one based on the small-area estimation and the other based on the principal component analysis of aggregate data. We also compare them against the rankings based on the local leaders. While all of the three produce reasonably...

The possibility of non-constant discounting is important in environmental and resource management problems where current decisions affect welfare in the far-distant future, as with climate change. The difficulty of analyzing models with non-constant discounting limits their application. We...
