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
Dalla triennale alla magistrale: continua la “fuga dei cervelli” dal Mezzogiorno d'Italia
No full textGuardando alla geografia della mobilità degli studenti meridionali negli anni accademici dal 2014/15 al 2017/18 nel passaggio dalla laurea triennale a quella magistrale, Massimo Attanasio, Marco Enea e Alessandro Albano rilevano che la fuga, già evidente nel passaggio dalle superiori all’università, continua anche in seguito: gli atenei del Mezzogiorno continuano a perdere iscritti potenziali a favore degli atenei del Centro-Nord
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

Micro drilling of hard-to-cut materials: An experimental analysis
No full textThe introduction of machine tools specifically designed and industrialised for micro cutting processes, the development of high performance micro tools, and the possibility of easily realising complex shaped surfaces have increased the competitiveness and the industrial interest on these processes. Consequently, many researchers are studying the phenomena involved in the mechanics of micro cutting processes. This paper is focused on the micro drilling process for difficult to cut materials. An experimental analysis, consisting tool life tests, was performed with the aim of highlighting limits and advantages of this cutting process. Three hard-to-cut alloys, namely AISI 310H stainless steel, Hastelloy C22 and Inconel 625 nickel based alloys, were tested. By using standard micro drills, holes 500 μm diameter with two different depths were realised by utilising peck drilling strategy. The final results showed that, differently from macro scale cutting, the workability of hard-to-cut materials at micro scale is mainly affected by the material ductility rather than its hardness
Parise e il visibile: il «sentimento dei sensi»
No full textIl saggio, attraverso sollecitazioni filosofiche e artistiche, indaga il ruolo del dato visivo nell’opera di Goffredo Parise, mettendo a fuoco in particolare il rapporto con la pittura di Filippo De Pisis. La riflessione proposta traccia, all’interno della scrittura parisiana, un itinerario dominato dalla preminenza dello sguardo, a partire dal Ragazzo morto e le comete, romanzo cinematografico e teatrale, fino ai Sillabari, dove il dato visivo si sedimenta in una più ampia indagine percettiva
John Attanasio Dedication

There is nothing that gives a teacher greater delight than a student who—in the words my own teacher Flemming James Jr. used about me—“pushes the quest further,” and so it is with John and me
