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...

This paper examines the theoretical foundations of precautionary wealth accumulation in a multi-period model where consumers face uninsurable earnings risk and borrowing constraints. We begin by characterizing the consumption function of individual consumers. We show that consumption function is...

In this paper, we incorporate a price search decision into a life cycle model and differentiate consumption from expenditure. Consumers with low wealth and bad income shocks search more for cheaper prices and pay less, which makes their consumption higher than in a model without search option. A...

This paper discusses the links between earnings, consumption and economic welfare inequality. It places emphasis on the role of leisure and labor supply in the assessment of cross-household inequality and argues that the documented increase of such inequality has its origin in the labor market....

In this paper, we study the interaction between self insurance and public insurance. In particular, we provide evidence on the relationship between unemployment insurance benefits and home production using the American Time Use Survey (ATUS) and the state-level unemployment insurance data of...

We reexamine the empirical relevance of habit formation preferences with micro-data on households' portfolio choices. We first derive the analytical solution to the risky asset share in a theoretical model with both habits and time-varying labor income. Our analytical results indicate that (1)...

According to the life-cycle theory, countries with high and rising youth ratios or high and rising old-age ratios tend to have low savings relative to investment, which depresses their capital outflows. This paper puts life-cycle theory to the test and studies the impact of demographic change on...

We estimate the long-run discount factor for a group of developed and developing countries through standard methodology incorporating adaptive expectations of inflation. We find that the discount factor of developing countries is relatively nearer to unity as compared to that of the developed...

Two key components of the upcoming health reform in the U.S. are a new regulation of the individual health insurance market and an increase in income redistribution in the economy. Which component contributes more to the welfare outcome of the reform? We address this question by constructing a...

Although the link between household size and consumption has a strong empirical support, there is no consistent way in which demographics are dealt with in standard life-cycle models. We study the relationship between the predictions of the Single Agent model (the standard in the literature)...
