Preferences, Spatial Prices and Inequality
研究了1999/2000至2009/2010年间印度农村价格对不平等的影响，基于EASI需求系统计算精确价格指数，发现通胀性质从累退变为累进，且时间与空间价格对不平等的影响不同。
This study examines the effect of prices on inequality in rural India during the period of economic reforms and beyond (1999/2000–2009/2010). It proposes a framework for calculating ‘exact’ price indices, based on the ‘Exact Affine Stone Index’ (EASI) demand system, and shows its usefulness by calculating spatial prices and regionally varying temporal prices that allow for both differences in preferences between states and over time. The study finds that the nature of inflation has been regressive during (1999/2000–2004/2005) and progressive during (2004/2005–2009/2010) and that the effects of temporal price inflation and spatial prices on inequality are qualitatively different.
