Kuhn-Tucker approach and its dual have been proposed to the demand system estimation when there are non-negativity bindings. However, empirical researchers have been struggling two decades in applying this method into practice due to: (1) the difficulty in derivation of a coherent econometric...

In this study, we develop and estimate a censored LA/AIDS model using household-level purchase data. In addition to imposing non-negativitity constraints, we account for the endogeneity of unit value. We address the non-negativity issue using an Amemiya-Tobin approach, which imposes the...

We study both empirically and theoretically the consequences of introducing a conditional cash transfer scheme for the distribution of program impacts. Intuitively, if the conditioned-on good is normal, then better-offhouseholds tend to receive a larger positive impact. I formalize this insight...

In this working paper we demonstrate that some of the statistical tests used by Huang and Smith in a recent Land Economics article (74(2 1998): 186-202) were erroneous, and raise concerns about their corresponding conclusions. Specifically, using data from one of the studies that they showcase,...
