I study the consumption-saving problem with non-separable utility under ambiguity. Using smooth ambiguity aversion, I show that the introduction of ambiguity and greater ambiguity aversion raise optimal saving. When relative prudence in ambiguity preferences is bounded by 2, also greater...

When the financial positions of pension funds worsen, regulations prescribe that pension funds reduce the gap between their assets (invested contributions) and their liabilities (accumulated pension promises). This paper quantifies the business cycle effects and distributional implications of...

The instability of wealth effect on consumption over the business cycles is widely recognized in recent empirical studies. We develop a consumption and investment problem for an investor with direct preference for wealth where the drift and volatility of asset return switches between two...

What are the cumulative effects of health shocks over the life-cycle? The answer depends on the nature of persistence of bad health and the extent to which it changes individuals' economic circumstances. We measure the lifetime costs of bad health using a rich structural model that can reproduce...

We develop an experimental production economy to study the general equilibrium and welfare effects of speculation and stabilization policies. Participants playing the role of household-investors interact in labor, output, and, in some treatments, asset markets. Without the ability to trade...

Motivated by experimental findings and the literature on modular brain functions, we simulate the intertemporal decisions of consumers affected by temptation. In this framework, the lack of self-control distorts agents choices and reduces their wellbeing. While their consumption behaviour is...

This paper studies the response of saving decisions to two alternative capital taxation, i.e., wealth tax and capital income tax. I conduct a "life-cycle" experiment on Amazon Mturk, where subjects make dynamic saving decisions. Subjects exhibit an overreaction to the wealth tax, not to the...

Most economic models assume that time preferences are stable over time, but the evidence on their long-term stability is lacking. We study whether and how time preferences change over the life cycle, exploiting representative long-term panel data. We provide new evidence that discount rates...

This paper examines the early effects of dismantling the one-child (fertility) policy, which China relaxed in 2013 and eliminated prior to 2017. Birth rates, female labor force participation, and saving behavior have already changed. Between 2015 and 2017, the proportion of households with...
