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)...

The utility function with traditional exponential discount cannot explain individuals´ problems of inter-temporal inconsistence and self-control. Several economists have explained these problems with what is known as “present-bias”. The present-bias means that a good becomes more tempting...

This study investigates the hypothesis that shifts in women’s relative income, which affects their bargaining power in the household, have discernible effects on aggregate saving due to differing saving propensities by gender. An analytical framework for pooled and non-pooled savings...

This paper shows that a Nash equilibrium consisting of strategies of choosing a Pareto inefficient transition path is selected by households even without frictions as a result of the revealed government failure in supervision of financial markets. The Pareto inefficiency causes the generation of...

This paper analyzes the optimal consumption behavior of a consumer who faces uninsurable labor income risk and borrowing constraints. In particular, it provides conditions under which the decision rule for consumption is a concave function of existing assets. The current study presents two main...

A disturbing feature of the conventional objective function for intertemporal decisions under uncertainty is that the agent's attitudes toward intertemporal substitution and risk aversion are entangled. This paper shows that, in contrast to common perception, the two attitudes can be completely...

Two key components of the upcoming health reform are a reorganization 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 general...

This thesis is built upon two core arguments. The first is the notion that the demographic transition should be narrated through the perspective of ageing rather than population growth and the second is that ageing on a macroeconomic level represents a strong driver of international capital...

Using the Chinese urban household survey data between 1997 and 2006, we find that income inequality has a negative (positive) impact on households’ consumption (savings), even after we control for family income. We argue that people save to improve their social status when social status is...

This paper investigates the impact of the desire to keep up with the Joneses (KUJ) on economic growth and optimal tax policy in a continuous time overlapping generations model with AK technology and gradual retirement. Due to the desire to KUJ, the propensity to consume out of total wealth rises...
