While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...

This paper analyzes the theoretical and quantitative implications of optimal capital taxation in the neoclassical growth model with aggregate shocks and incomplete markets. The model features a representative-agent economy with proportional taxes on labor and capital. I first consider the case...

A key rationale for fiscal stimulus is to boost consumption when aggregate demand is perceived to be inefficiently low. We examine the ability of the government to increase consumption by evaluating the impact of the 2009 "Cash for Clunkers" program on short and medium run auto purchases. Our...

We specify a structural life-cycle model of consumption, labour supply and job mobility in an economy with search frictions that allows us to distinguish between different sources of risk and to estimate their effects. The sources of risk are shocks to productivity, job destruction, the process...

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...

A dynamic model of the demographic structure of Japan is summarized. It is capable of tracing the dynamic development of the Japanese population, including the distribution of families by age, sex, and marital status of the head, as well as by the number and age of children and other dependents....

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....

Using comprehensive account records, this paper examines how individuals respond to a temporary drop in income following the 2013 U.S. Federal Government shutdown. Affected employees saw their income decline by 40% on average, which was recovered within two weeks. Despite having no effect on...

China has experienced remarkably stable growth and inflation in recent years according to official statistics. We construct alternative estimates using detailed information on Chinese household-purchasing patterns. As households become richer, a smaller fraction of total expenditures are spent...

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, virtually all previous studies as well as the...
