Intertemporal choice and the cross-sectional variance of marginal utility
No full textThe theory of intertemporal choice predicts that the cross-sectional variance of the marginal utility of consumption is equal to its own lag plus a constant and a random component. Using general preference specifications and some assumptions about the nature of the random component, we provide an explicit test of this hypothesis. Our approach circumvents the necessity to identify a pure age profile of the cross-sectional variance of consumption and yields a well-specified statistical test. This test is applied to data from the United States, the United Kingdom, and Italy. The results are remarkably consistent with the restrictions implied by the theory of intertemporal consumption choices
Inequality in Living Standards since 1980: Income Tells Only a Small Part of the Story
No full textStudies of wage and income inequality among U.S. citizens over the past thirty years have engendered the common wisdom that the rich are getting richer and the poor are getting poorer. But is it really that simple? In this meticulous economic study, Orazio P. Attanasio, Erich Battistin, and Mario Padula contend that the evolution of income and wage inequalities offers only a partial picture of changes in prosperity in recent decades. Studying changes in the distribution of consumption and expenditure helps to amplify this picture--income, after all, is valued in large part because it allows consumption--and yields a more complete understanding of economic well-being in America.
Inequality in Living Standards since 1980: Income Tells Only a Small Part of the Story finds that income-poor households do not always coincide with consumption-poor households--income-poor households often report spending considerably higher than their income level. Income and consumption patterns also vary according to the age and education level of an individual or household head; a thorough and nuanced understanding of economic well-being should therefore consider both differences across groups and inequalities within groups. Finally, examining income levels in conjunction with consumption patterns provides valuable insights about the nature of income shocks that affect households (whether positive or negative) and the instruments available for smoothing out these shocks, such as personal savings, borrowing, and private or public transfers. Temporary shocks may not affect consumption and welfare at all, while the effects of permanent shocks on the same variables are more significant.
Has economic inequality worsened in the United States since 1980? Attanasio, Battistin, and Padula conclude that although inequality as measured by consumption has increased, that increase is not as large as when inequality is measured by income and wages alone. This thorough analysis has important implications for the design of U.S. economic policy and welfare programs in the twenty-first century

Quali atenei scelgono i diplomati del Mezzogiorno d’Italia?
No full textLa geografia della mobilità degli studenti meridionali nel passaggio dalle superiori all’università è qui analizzata nel periodo che va dal 2011/12 al 2016/17 (anni scolastici o accademici). I dati, analizzati da Massimo Attanasio, Marco Enea e Andrea Priulla mostrano una fuga allarmante, e persino crescente nel tempo, dal Mezzogiorno verso gli atenei del Centro- Nord
Risk sharing in private information models with asset accumulation: explaining the excess smoothness of consumption
No full textWe study testable implications for the dynamics of consumption and income of models in which first-best allocations are not achieved because of a moral hazard problem with hidden saving. We show that in this environment, agents typically achieve more insurance than that obtained under self-insurance with a single asset. Consumption allocations exhibit "excess smoothness," as found and defined by Campbell and Deaton (1989). We argue that excess smoothness, in this context, is equivalent to a violation of the intertemporal budget constraint considered in a Bewley economy (with a single asset). We also show parameterizations of our model in which we can obtain a closed-form solution for the efficient insurance contract and where the excess smoothness parameter has a structural interpretation in terms of the severity of the moral hazard problem. We present tests of excess smoothness, applied to U.K. microdata and constructed using techniques proposed by Hansen, Roberds, and Sargent (1991) to test the intertemporal budget constraint. Our theoretical model leads us to interpret them as tests of the market structure faced by economic agents. We also construct a test based on the dynamics of the cross-sectional variances of consumption and income that is, in a precise sense, complementary to that based on Hansen, Roberds, and Sargent (1991) and that allows us to estimate the same structural parameter. The results we report are consistent with the implications of the model and are internally coherent
Food and Cash Transfers: Evidence from Colombia
No full textWe study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total consumption and for the price variability across villages, our estimates imply that an increase in consumption by 10% would lead to a decrease of 1% in the share of food. However, quasi-experimental estimates of the impact of the programme show that the share of food increases. This result is not inconsistent with the hypothesis that the programme could increase the bargaining power of women, inducing a more than proportional increase in food consumption
Consumption and Saving: Models ofIntertemporal Allocation and TheirImplications for Public Policy
No full textThis paper provides a critical survey of the large literature on the life cycle model of consumption, both from an empirical and a theoretical point of view. It discusses several approaches that have been taken in the literature to bring the model to the data, their empirical successes, and their failures. Finally, the paper reviews a number of changes to the standard life cycle model that could help solve the remaining empirical puzzles
Mexico in the 1990s: the main cross-sectional facts
No full textThis paper describes the main cross-sectional facts on individual and household earnings, labor supply, income, consumption and wealth in Mexico in the decade of the 1990s. We use two different data sources: the Mexican Employment Survey (ENEU) and the Mexican Income and Expenditure Survey (ENIGH). The contribution of this paper is twofold. First, we integrate the two surveys to provide a complete characterization of the changes in employment, wages, income, consumption and wealth in the 1990s. Second, we highlight some distinctive features that characterize the Mexican economy in this decade. In particular, we focus on the changes in the size of the informal sector and we study the relationship between changes in informality and changes in wage inequality. © 2009 Elsevier Inc.
