Gli scenari legati alle modalità attraverso cui si incrocia la domanda con l’offerta di lavoro flessibile risultano essere alquanto ardui da illustrarsi. Nel presente lavoro, dopo aver presentato i principali ostacoli oggi esistenti, si evidenziano, in riferimento alla figura delle prestazioni coordinate e continuative, le modalità attraverso cui tale inrocio risulti essere intercettabile attraverso la Rilevazione Continua sulle Forze di Lavoro dell’Istat accompagnate da una loro analisi numerica.

Historically, consumer behaviour has always been a subject of great interest for economists. Indeed, the theoretical and empirical approaches to the analysis of consumption phenomenon represent two interrelated, though autonomous, veins of research on a subject, which has undergone substantial conceptual changes over time to reach its present form. This paper provides a comprehensive study of consumer behaviour in Italy over the period 1970-2007. Traditionally, this type of studies gives partial and biased description of household spending habits because based on individual/few groups of commodities. This paper provides a de tailed assessment of the phenomenon by considering simultaneously all the first twelve divisions of the COICOP through two broad levels of analysis. The first is an analytic description of the key patterns of Italian consumption in volume terms, budget shares and relative prices over the period analysed with data from the Italian Institute of National Statistics. The second is an empirical evaluation of the phenomenon through the implementation of two classic functional forms. Specifically they are the Indirect Translog System as defined by Christensen, Jorgenson and Lau (1975), and the Generalised Leontief model as proposed by Diewert (1974). An economic and econometric comparison of outcomes is also worked out. Results indicate consumption habits, income and relative price differentials as main factors influencing consumer behaviour.

L’attuale scenario economico rivela in modo fin troppo evidente come sia in atto un processo di mutamenti organizzativi che stanno di fatto imponendo un maggiore utilizzo delle forme di lavoro flessibile. L’impatto che le forme di lavoro flessibile hanno sullo scenario economico è certamente frutto di interventi normativi che ne disciplinano gli aspetti fiscali, lavoristici e previdenziali, nonché oggetto di studio in ambito giuridico, ma per poter essere analizzato compiutamente deve essere affiancato da analisi quantitative atte ad indagare su ciò che in effetti accade seguendo un’ottica non solo microeconomica, ma soprattutto macroeconomica. Il presente lavoro analizza la tipologia di lavoro atipico identificata dai rapporti di lavoro occasionale è stata condotta attraverso l’elaborazione dei micro dati su base trimestrale relativi alla Ricerca continua sulle Forze di Lavoro per gli anni dal 2004 al 2007.

Owing to the considerable complexity of obtaining balanced accounting systems simultaneously at both constant and current prices, most countries publish national accounting data at current prices and only for a small number of aggregates at constant prices. In this paper, a suitable method is proposed to balance a very large set of National Accounts simultaneously at current and constant prices. The method is more flexible compared to the others in literature, and allows the consistency of the system of deflators to be controlled. An application to the Italian 2006 Supply-Use tables has been worked out, and it has yielded good outcomes.
