In an exchange economy in which there is a complete set of markets for macroeconomic risks but no market for idiosyncratic risks, we consider how the efficient risk-sharing rules for the macroeconomic risk are affected by the heterogeneity in the consumers' risk attitudes and idiosyncratic...

A univariate real-valued function is said to be completely monotone if it takes positive values and alternate the signs of its higher order derivatives, starting from everywhere negative first derivatives. We prove that the representative consumer's discount factor of a continuous-time economy...

We examine the risky choices of contestants in the popular TV game show “Deal or No Deal” and related classroom experiments. Contrary to the traditional view of expected utility theory, the choices can be explained in large part by previous outcomes experienced during the game. Risk aversion...

We study how the 1997-1998 Asian Financial Crisis affected consumption smoothing across households in Korean prefectures. The crisis caused the cross-sectional mean and volatility of household consumption to fall substantially. We show that such falls bias two standard tests towards rejecting...

This paper is based on a two-stage model of an incumbent firm and a potential entrant. We consider two cases in terms of strategic relevance between both firms. We also consider both price-setting competition and quantitysetting competition. Therefore, we examine four cases. Each case is...

This paper studies the empirical relationship between consumption and saving under two different sources of uncertainty: financial risk and environmental risk. The analysis is carried out using time series data for six advanced economies in the period 1965-2007. The results support the...

This article evaluates the predictive performance of the market variance risk premium (VRP) in Japan on the Nikkei 225 returns, credit spreads, and the composite index of coincident indicators. Different measures such as expected and ex-post VRPs, which are constructed from model-free implied...

This paper investigates the existence and degree of variation across house holds and over time in the intertemporal elasticity of substitution (IES) and the coefficient of relative risk aversion (RRA) that is generated by habit forming preferences. To do so, we develop a new nonlinear GMM...

We investigate how childbirth affects intrahousehold resource allocation for married Japanese couples. We develop reduced-form and structural-form specifications from a unified theoretical framework. Under a weak set of assumptions, we can focus on private goods to track the changes in...
