| While China's economic reform has brought about significant economic growth, there is a considerable debate about the impact of such market-oriented reform on income and welfare distributions. This paper examines the changes in income and welfare distributions in urban China from 1981 to 1998 and discusses implications for China's food consumption patterns and trade behavior. While the Lorenz curves estimated using Kakwani's interpolation method indicate that the level of income inequality in urban China has increased significantly since 1981, welfare comparisons based on generalized Lorenz curves suggest that the rise in real average income has more than compensated for the increase in inequality and has therefore brought about continuous improvement... |

| This article proposes a semiparametric two-step procedure for estimating a censored consumer demand system with micro data. The semiparametric estimator considered in the first step is suggested by Klein and Spady (1993). This estimator, used as a counterpart of the probit estimator in a conventional two-step model, does not make any distributional assumptions about the disturbances and so is exempt from model misspecification and plausible heteroscedasticity. In the second step, we motivate the choice of the Almost Ideal Demand System (AIDS) as an economic representation of consumers' demand behavior. Implementing our proposed semiparametric two-step procedure as well as Shonkwiler and Yen (1999)'s two-step model to a household meat consumption dataset... |
