SVILUPPI DELLA FOTOELASTICITÀ RGB

Questa memoria considera le caratteristiche della fotoelasticità RGB con riferimento al massimo ordine di frangia rilevabile che dipende dalla modulazione del segnale, dalla sorgente luminosa, dalla presenza di colori simili e dal gradiente delle frange. Le esperienze mostrano che la lampada ad incandescenza consente di rilevare ritardi fino a circa 4 ordini di frangia mentre la lampada a fluorescenza consente di determinare ordini di frangia ben più elevati (12 in questa memoria) grazie alla natura discreta della sorgente

Political institutions and central bank independence revisited

We build on earlier studies regarding Central Bank independence (CBI) by relating it to political, institutional and economic variables. The data suggest that CBI is positively related to the presence of federalism, the features of the electoral system and parties, the correlation between the shocks to the level of economic activity in the countries included in the sample and, for a sub-sample of economies, the convergence criteria to join the European Monetary Union (EMU).ICentral Bank independence; institutional systems; variable selection

The Federal Funds Rate and the Conduction of the International Orchestra

In the first ten years of EMU, monetary policy choices of the European Central Bank (ECB) in setting the short-term interest rate have followed, systematically, monetary policy decisions made by the Federal Reserve System (Fed). For, despite the presence of variable lags with respect to Fed decisions, turning points of European short-term interest rates have been largely anticipated by movements in the federal funds rate. In this paper we show that, in the context of a bivariate cointegrated system, a clear long-run US dominance emerges. Moreover, the structural analysis reveals that a permanent increase in the federal funds rate causes a permanent one-for-one movement in the eonia rate.Monetary policy; Identification; Structural Cointegrated VARs

L'efficacia e l'efficienza dei processi di pagamento delle PP.AA. e la riforma federalista.

La “cattiva pratica” del ritardo nei pagamenti delle transazioni commerciali sembra essere diventata un’abitudine consolidata nei rapporti tra i privati e le Pubbliche Amministrazioni, un’abitudine che costituisce, fra l’altro, un motivo di instabilità in più per le imprese, già costrette a confrontarsi con un difficile scenario macroeconomico caratterizzato da prospettive future incerte e da crescenti difficoltà di accesso al credito. La questione posta in questo saggio non riguarda, tuttavia, soltanto il corretto rapporto che dovrebbe instaurarsi tra le imprese e gli Enti locali. Essa investe anche altre importanti questioni: quella del significato del bilancio, quale luogo nel quale le preferenze della collettività amministrata sono definite, sono poste a fronte delle risorse disponibili e danno luogo, sul piano giuridico, ad affidamenti, ad oneri, a responsabilità; quella del dissesto, riferito alla impossibilità, cui per la via dei ritardi nei pagamenti si giunge, di assicurare ai cittadini la corretta gestione dei servizi; quella del significato dei vincoli che lo Stato impone, vincoli che impediscono una corretta implementazione delle procedure contabili e che possono produrre aggravi di costo e disfunzioni difficilmente giustificabili; ed infine quella importantissima della corretta interpretazione ed attuazione dell’articolo 119 della Costituzione e della sostenibilità finanziaria (nel medio-lungo periodo) del sistema pubblico, inteso nel suo complesso. Da essa dipende, infatti, anche la tanto auspicata attuazione della riforma federalista, che è stata ormai avviata in Italia con l’emanazione della legge delega n. 42 del 5 maggio 2009

The Italian Labour Market and the Crisis

The aim of this paper is to analyse the effects of the crisis on the Italian labour market. The Italian labour market is characterized by deep gender differences and regional variability. The data show that the crisis lead to an increase in the gap of female employment rates and women?s inactivity rates with respect to Europe. The North of Italy experienced a higher increase in unemployment than the South, where many people withdrew from the labour market because of poor employment prospects. Moreover, in Italy, the increase in unemployment has been mitigated by the increase in the number of workers having access to the wage supplementation fund who are not computed within the unemployed. However, the heterogeneity in the system of unemployment benefits increased inequalities amongst the unemployed. Using a micro simulation techniques, we estimate the effect of the crisis on income distribution and poverty and find that at the national level, the population showed a reduction in equivalised household income by about 1 percent. The limited impact on household?s equivalent income can be connected to the relatively high share of unemployed who are young with relatively low income and sustained by other members of the householdlabour market, poverty, economic crisis

Are defined contribution pension schemes socially sustainable? A conceptual map from a macroprudential perspective

If the combined retirement income, provided by public and private defined contribution (DC) pension schemes, falls below socially acceptable standards, there is a political risk that consensus seeker policymakers could yield to pressures to commit future fiscal revenues. These contingent liabilities, when incorporated in markets’ expectations, are bound to create spillovers on sovereign risk, with negative feedback loops on the capital adequacy of banks and of other intermediaries, owing to losses on their government paper. Among the causes of reduced annuities out of the final assets in DC pension funds is an equity risk premium much lower than the commonly values advertised by the industry and by policymakers. From a macroprudential perspective, this political risk should be taken into account in stress tests assessing banks’ resilience to financial shocks.pensions, equity risk premium, political risk, sovereign risk, stress test;

The Fragile Definition of State Fragility

We investigates the link between fragility and economic development in sub-Saharan Africa over a yearly panel including 28 countries for the 1999-2004 period. Beside the conventional definition of fragility adopted by the OECD Development Assistance Committee, we introduce the more severe definition of extreme fragility. We show that only the latter exerts a significantly negative impact on economic development, once standard economic, demographic, and institutional regressors are accounted for. As a by-product of this investigation we produce up-to-date evidence on the growth performance of the area. We find a tendency to convergence and no influence of geographic and historical factors.State fragility; growth; Africa; aid.
