Using food prices and consumption to examine Chinese cost of living

Abstract

AbstractThis paper considers two approaches to examining potential bias in China's consumer price index: (i) inferring true changes in cost of living from consumer behaviour; and (ii) creating alternative price indices to compare with official indices. For (i), our semi‐parametric estimates agree with the recent finding of a large understatement in increases to the true cost of living. For (ii), we focus on food prices and explore potential causes of bias. We find some evidence of a new‐good bias. China's large‐scale migration also causes changes in the cost of living that are not reflected in the consumer price index.
