Objective To re-estimate price elasticity of different income groups’ demand for cigarette in terms of the lastest national tobacco consumption data and provide policy-makers with evidence to make decision on public policy of tobacco control. Methods A total of 16 056 adults of different income were surveyed in 27 provinces in 2002 and the data analyzed by using two-part model (logistic and log-linear model). Results We found that the demand elasticities were -0.589, -0.234, -0.017 and 0.247 for the poor group, low income group, middle income group and high income group, respectively. Conclusions Increasing tobacco tax will result in decreasing more cigarette consumption of lower income groups than higher groups, bearing more taxation of higher income groups than lower income groups, therefore tobacco taxation is not regressive.
Objective To investigate the elasticity of demand for health care services in China, and to provide suggestions for further studies. Methods Databases including PubMed, The Cochrane Library (Issue 10, 2015), EMbase, CNKI, VIP and WanFang Data were searched from inception to December 2015 to collect studies about price elasticity or income elasticity of demand for health care services. Literatures were screened and related information was independently extracted by two reviewers. Then qualitative approaches were applied to describe the elasticity. Results A total of 31 studies were included. Estimates of the own-price elasticity of demand for health care services ranged from –2.520 to 2.944 in 25 studies; 2 studies estimated cross-price elasticity between outpatient and inpatient service and one study estimated cross-price elasticity between different levels of inpatient services and all estimates were positive; Estimates of the income elasticity ranged from –0.020 to 2.480 in 28 studies. Demand for inpatient services was more income sensitive than the demand for outpatient services and urban citizens were more sensitive to income than their rural counterparts. Conclusion Health service is insensitive to price and belongs to necessity; inpatient service and outpatient service are substitutes for each other and different levels of inpatient services are substitutes for each other; government are supposed to tackle with the unbalanced increase of the demand of outpatient and inpatient services along with the increase of income to guide rational health-seeking behaviors.
