| The specification and estimation of models of consumer and producer demand with kink points are considered. The presence of kink points divides the demand or production schedule into different regimes. Our approach utilizes the concept of virtual prices. The virtual prices transform binding quantities into nonbinding ones and provide a rigorous justification for structural change in the observed demand functions across regimes. The comparison of virtual prices with market prices determines regime occurences. An application to energy demand in Indonesian manufacturing firms based on the translog cost function is provided. |

| In this paper, we demonstrate the difficulties of identifying both the own- and cross-effects of health on the allocation of time within a household, and develop and implement a method for estimating the effects of infant morbidity on the differential allocation of time by other family members based on discrete indicators of health and of activity participation commonly available in survey data. Estimates obtained from Indonesian household data indicate that inattention to problems of the measurement and endogeneity of health leads to a substantial underestimate of the effects of variations in child morbidity on the intrahousehold division of labor, and our estimates that take into account the "simultaneity" of health-activity associations indicate that... |

| In this paper we assess the importance of heterogeneity and selective fertility in altering estimates and interpretations of the determinants of the human capital of children. We set out a sequential model of human capital investments in children incorporating endogenous fertility and heterogeneity in human capital endowments to illustrate the fertility selection problem and issues of identification. Empirical results based on parametric and semi-parametric estimates of selectivity models applied to data on birthweight and schooling in Malaysia indicate that the hypothesis of no fertility selection is strongly rejected, with mothers having higher birthweight children tending to have substantially lower birth probabilities (negative birth selectivity). As a... |

| This paper provides a theoretically consistent approach to estimating demand relationships in which kink points occur either in the interior or on the vertices of the budget set. There are important classes of problems in developing countries which demonstrate such kinked budget sets including binding non-negativity constraints. This paper also extends these methods to the estimation of production structures. As an application a translog cost function for three energy inputs is estimated from cross-sections of individual Indonesian firms. |

| This paper investigates the determinants of rice seed variety choice in Indonesia with respect to a meta-profit function. Varietal choice is modeled as depending on the profitability of high yielding varieties of seed relative to traditional varieties of seed, the schooling of cultivators and factors associated with yield uncertainty and risk aversion. Careful attention is paid to the stochastic structure of the estimated simultaneous equations switching regimes model. The maximum likehood method applied to Indonesian farm-level data is complicated by endogenous regressors and heteroskedastic errors. Adoption of high yielding varieties was found to be positively associated with its relative profitability, the likelihood of flooding, quality of irrigation... |
