Obesity has become a major health issue. Research in economics has provided important insights as to how technological progress reduced the relative price of food and contributed to the increase in obesity. However, the increased availability of food might well have overstrained will power and...

In this paper, I survey the previous literature on the saving behavior of the aged in Japan and then present some survey data on the saving behavior of the aged in Japan that became available recently. To summarize the main findings of this paper, all previous studies as well as the newly...

We estimate the elasticity of charitable giving with respect to its price and after-tax income using a panel of over 550,000 disproportionately high-income tax returns spanning the years 1979 through 2005. Improvements relative to the previous literature include: using state tax variation to...

This paper investigates the co-movements of job security perceptions and household saving rates using data from the 1992 to 2010 waves of the German Socio-Economic Panel. The empirical analysis reveals that higher job insecurity is generally accompanied by slightly lower saving which suggests...

This paper measures how households smooth changes in consumption when incomes are shifted by permanent or transitory shocks at country and regional level. I compute insurance capacity using the Spanish Continuous Family Expenditure Survey skipping the imputation methods used by the previous...

We estimate the importance of preference interdependence from consumption choices. Our strategy follows the literature that tests the constraints imposed by optimality in the evolution of individual consumption. We derive a Euler equation from a preference specification that allows for...

This paper studies how demographic variation affects the aggregate household saving rate. We focus on China because it is experiencing an historic demographic transition and has had a massive increase in household saving. We conduct a quantitative investigation using a structural overlapping...

In response to income fluctuations, households smooth consumption by substituting between market expenditure and time inputs. This paper provides evidence of this substitution in the context of food consumption over transitory and permanent income fluctuations in Mexico. Household time...

We investigate partial insurance and group risk sharing in extended family networks. Our approach is based on decomposing income shocks into group aggregate and idiosyncratic components, allowing us to measure the extent to which each is insured, having accounted for public insurance programs....

Endogeneity between health and wealth presents a challenge for estimating causal effects of health shocks. Using a quasi-experimental design, comprising exogenous shocks sustained as bus accident injuries in India, with controls drawn from travelers on the same bus routes one year later, I...
