Consumption is the largest component of GDP. Since the 1950s, the life cycle and the permanent income models have constituted the main analytical tools to the study of consumption behavior, both at the micro and at the aggregate levels. Since the late 1970s the literature has focused on versions...

This paper presents an (S,s) model for automobile consumption and estimates it using a data set of US households. The model allows for unobserved heterogeneity in both the target level and the band width, takes into account the possibility of a zero desired level, constrains the band to be non...

Liquidity constraints and, more generally, imperfections in credit markets, can be extremely important for the intertemporal allocation of consumption and have received a substantial amount of attention in the theoretical and empirical literature on consumption. In the first part of the paper I...

In this paper I analyze the pattern of saving behavior by U.S. households, using the Consumer Expenditure (CEX) Survey. The analysis' main goal is to explain the decline in aggregate personal saving in the United States in the 1980s. I estimate a typical' saving-age profile and identify...

In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of the preference parameters. When utility is isoelastic and a sample covering a long time period is available, consistent estimates are obtained from...

Children's experiences during early childhood are critical for their cognitive and socio-emotional development, two key dimensions of human capital. However, children from low income backgrounds often grow up lacking stimulation and basic investments, leading to developmental deficits that are...

We propose a rich model of household behavior to study the effect of two important policies: mortgage interest tax deduction and mandatory mortgage amortization. These policies have attracted some controversy, first because they are conceived to increase overall saving, an objective that the...
