Demand Systems Estimation with Microdata: A Censored Regression Approach

Equivalence scales, the cost of children and household consumption patterns in Italy

“…Starting from the early work of Heien and Wessels (1990), estimation procedures for censored consumer demand systems have been developed and include the efficient Generalized Maximum Entropy procedure (Golan et al 2001) and consistent but less efficient approaches such as Perali and Chavas (2000) multistep procedure and Shonkweiler and Yen (1999) Two-Step (TS) estimator involving probit estimation in the first step and a selectivity-augmented equation system in the second step. 8 We use the TS procedure by Shonkwiler and Yen (1999) due to its simplicity.…”

The Demand for Books Estimated by Means of Consumer Survey Data

“…5 Attempts have been made to combine models and methods for censored data like the Tobit method with models and methods for simultaneous equations like AIDS, cf. Amemiya (1979) and Heien and Wessells (1990). There are several unsettled issues in this context, and thus we have not explored their performance.…”

A censored system of demand analysis to unpacked and prepackaged milk consumption in Turkey

“…Results are used to obtain the missing prices for those households which do not report the product in question. Several studies provide the description of properties of this computation (Gourieroux and Monfort 1981;Heien and Wessells 1990) used extensively in the microeconometric studies (Diansheng et al 2004;Diansheng and Kaiser 2005;Yen and Lin 2006). Once missing implicit prices are computed, we then compute the quality-adjusted prices because calculated implicit prices may reflect more than spatial variation caused by supply shocks (i.e., transportation costs, cost of where milk is produced, seasonal variation, etc.).…”

“…The procedures that do not specifically account for censoring in the dependent variables result in biased and inconsistent demand estimates (Yen et al 2004;Yen 2005a,b). Pazarlioglu et al (2007) and Akbay et al (2007) did realize to accommodate censoring with the two-step procedure of Heien and Wessells (1990) but did not correct the standard errors of the parameter estimates at the second step. Shonkwiler and Yen (1999) showed that the aforementioned procedure is incorrect analytically and performs poorly in Monte Carlo simulations even in the presence of corrected standard errors of parameters of the second step.…”
