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 household decisions when individual utility depends on a consumption reference level. The desire to ``keep up with the Joneses'' represents one such example. The prior literature shows that, in a Ramsey model, consumption externalities have no impact on steady state...

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...

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 paper sets up a dynamic general equilibrium model to study how the composition of technical progress affects the asymptotic speed of convergence. The following questions are addressed: Will endogenizing a fraction of the productivity increases as coming from learning by investing help to...

In the quantitative macro literature, single agent models are heavily used to explain "per-adult equivalent" household data. In this paper, we study differences between consumption predictions from a single agent model and "adult equivalent" consumption predictions from a model where household...

In the quantitative macro literature, single agent models are heavily used to explain "per-adult equivalent" household data. In this paper, we study differences between consumption predictions from a single agent model and "adult equivalent" consumption predictions from a model where household...

In the quantitative macroeconomics literature, single agent models are widely used to explain ``per-adult equivalent'' data, which are obtained at the household level. In this paper we suggest a simple framework to understand the sources of bias when these models are used to make predictions for...

Homotheticity induces a dramatic statistical bias in the estimates of the intratemporal and intertemporal substitutions. I find potent support in favor of nonhomotheticity in aggregate consumption data, with nondurable goods being necessities and durable goods luxuries. I obtain the...

The aim of this paper is to gain insights from studying adaptation to natural disasters in the past in order to analyze optimal adaptation in Switzerland in the future. Most adaptation measures already undertaken in Switzerland are so-called reactive measures. They may be eective, but not...
