Identifying the depreciation rate of durables from marginal spending responses

This paper presents a novel method to estimate the depreciation rate of durable goods using a combination of identified marginal and average spending shares. We apply our method to Chinese spending responses to disposable income changes induced by monetary policy in 2008-2009. The marginal spending response is 0.40. Durable goods make up about 45% of this marginal spending response. By combining this marginal spending share on durables with an average spending share of 14%, we estimate the annual depreciation rate of durables in China to be 0.16.publishedVersio

Fertility Cost, Intergenerational Labor Division, and Female Employment

China has set to increase the minimum retirement age, to ease the pressure from pension expenditure and the falling labor supply caused by the aging population. However, policy debates have so far neglected the crucial fact that families in China largely rely on retired grandparents for childcare. Using novel and high-quality survey data, we demonstrate that intrafamily downward labor transfer towards childcare significantly increases young females’ labor force participation rate and their labor income, and such effects do not exist for males. Furthermore, we show that the positive effects from grandparental childcare are higher for better-educated, urban females with younger children. This paper thus reveals a large, hidden cost in the new retirement policy — the reduced feasibility of grandparental support, due to postponed retirements, may crowd out productive labor of young females, — and rationalizes a series of social protection policies to accompany the phase-in of the new retirement scheme
