An intriguing problem in stochastic growth theory is as follows: even when the return on investment is arbitrarily high near zero and discounting is arbitrarily mild, long run capital and consumption may be arbitrarily close to zero with probability one. In a convex one-sector model of optimal...

The recent literature has shown that income inequality is one of the main causes of borrowing and debt accumulation by working households. This paper explores the possibility that household indebtedness is an important cause of rising income inequality. If workers experience rising debt burdens,...

This paper studies the effect of digitalization on consumption inequality. We assemble a novel dataset of digital technology in the consumption basket of US households and establish a new stylized fact: High-income households have a higher consumption share of digital products than low-income...

This paper studies how digitalization affects consumption inequality. We assemble a novel dataset of digital technology used in the production process, link it to US consumption data and establish a new stylized fact: High-income households consume a higher share of digitally produced products...

Various deviations from the Permanent Income consumption model with rational expectations have been discussed in the literature, including loss aversion and liquidity constraints. In the existing literature, these two types of consumption asymmetry are usually considered as mutually exclusive....

This paper tests how subjects behave in an intertemporal consumption/saving experiment when borrowing is allowed and whether subjects treat debt differently than savings. Two treatments create environments where either saving or borrowing is required for optimal consumption. Since both...

This paper investigates the behaviour of estimators based on the Kullback-Leibler information criterion (KLIC), as an alternative to the generalized method of moments (GMM). We first study the estimators in a Monte Carlo simulation model of consumption growth with power utility. Then we compare...

This paper empirically estimates a micro-founded model which studies the macroeconomic impact of environmental and financial risks on consumption choices in the Mediterranean Region. The analysis is carried out using time series aggregate data for fourteen Mediterranean countries over the period...

Carroll and Kimball (1996) show that the consumption function for an agent with time-separable, isoelastic preferences is concave in the presence of income uncertainty. In this paper I show that concavity breaks down if we abandon time-separability. Namely, if an agent maximizing an isoelastic...
