Towards monetary constitutionalism in Italy

Various facts which belong to the past, present, and future of Italy, which concern both politics and economics, and which are relevant within a broad discussion of monetary policy support the request for a constitutionalization of the target of monetary stability. The authors are grateful to James M. Buchanan for his encouragement in carrying out the research and to an anonymous referee of this journal for his helpful comments on an earlier version of the paper.     

A Model of Employment in the Arts

The behaviour of artists appears to be influenced by non-pecuniary benefits that lead to employment choices inconsistent with traditional expectations of labour supply theory. The paper develops a model of employment in the arts with similarities to the Harris-Todaro model. Seemingly paradoxical results arise. For example, the model illustrates how an increase in wage rates for non-artistic activity may lead to a reduction in the amount of non-artistic activity and a commensurate increase in the amount of time devoted to artistic endeavours. Additionally, the model illustrates how individual work preferences of artists can lead to substantial underemployment in the arts.     

Criteri di sensitività in problemi di dominanza stocastica

Questo lavoro fornisce condizioni di dominanza stocastica di 1°, 2° e 3° ordine per problemi di decisione in condizioni d'incertezza, quando sia nota la funzione d'utilità solo in un numero finito di punti e quando le funzioni di ripartizione dei guadagni aleatori s'intersecano più d'una volta.     

Optimal demand policies against stagflation

Zusammenfassung Optimale Nachfragepolitik zur Bek?mpfung der Stagflation. — Der Aufsatz besch?ftigt sich mit der Wahl einer optimalen Gesamtnachfrage-Politik als Antwort auf einen inflation?ren Schock — optimal in dem Sinne, da\ die Volkswirtschaft zur Vollbesch?ftigung und Preisstabilit?t auf einen Pfad zurückgeführt wird, der die sozialen Kosten minimiert. Es wird die Ansicht vertreten, da\ die Kosten eines gegebenen Stabilisierungspfades proportional sind zu den über die Zeit aufsummierten Abweichungen der Inflationsrate und der Arbeitslosenquote von den langfristigen Zielwerten. Auf der Grundlage einer sehr allgemeinen Formulierung der Phillips-Kurve wird die optimale wirtschaftspolitische Antwort auf einen Inflationsschock analysiert und gezeigt, da\ sie gew?hnliche ?Turnpike?-Eigenschaften besitzt. Dieser Ansatz wird veranschaulicht, indem er auf die USA für den Zeitraum 1971–1975 angewandt wird, wobei die Sensitivit?t des optimalen Pfades in bezug auf alternative Wohlfahrts-Bewertungen und Ansichten hinsichtlich der Natur des Trade-off untersucht wird.

Résumé Les politiques de demande optimum contre la stagflation. — Cet article a pour sujet la selection d’une politique de demande agrégée optimum en réponse à un choc — optimum de manière qu’elle reconduit l’économie au plein emploi et à la stabilité de prix le long d’un sentier d’inflation-ch?mage minimisant des frais sociaux de ?welfare?. Nous arguons que les frais du chaque sentier donné de stabilisation peuvent être pris comme proportioneis à l’excès d’inflation et de ch?mage au-dessus du but à long terme, cumulé sur le sentier. En se fiant à une expression très générale de la ?courbe de Phillips? l’article analyse et démontre la réponse de politique optimum à un choc inflationniste pour exhiber des simples ?barrières? propriétés. L’approche est illustrée par l’application sur les E. U. pour la période de 1971 à 1975. Elle explore la sensibilité du sentier optimum aux évaluations alternatives de ?welfare? et aux vues de la nature du ?trade-off?.

Resumen Políticas óptimas de demanda contra la estagflación. — Este artículo se ocupa de la selección de una política de demanda agregada óptima en respuesta a un ?shock? óptimo inflacionario en el sentido que devuelve el pleno empleo y la estabilidad de precios a la economía a través de una trayectoria de inflación-desempleo minimizando los costos sociales de bienestar. Se argumenta que el costo de cualquier trayectoria de estabilización dada puede tomarse como proporcional al exceso de inflación y desempleo por sobre la meta de largo plazo, acumulado a través de la trayectoria. Basándose sobre una formulación muy general de la ?curva de Phillips? se analiza la respuesta de política óptima a un ?shock? inflacionario y se muestra que exhibe propiedades simples de Camino de portazgo. El enfoque se ilustra aplicándolo a los EEUU para el período 1971–75, investigando la sensibilidad de la trayectoria óptima con respecto a evaluaciones de bienestar alternativas y apreciaciones sobre la naturaleza del ?trade-off?.

Scelta tra alternative incerte con informazioni parziali sulle funzioni di utilità

In questo lavoro si considera la classe dei decisori avversi al rischio e per questa classe viene proposto un metodo per verificare la dominanza stocastica tra due possibilità in alternativa quando la funzione d'utilità sia nota soltanto in un numero finito di punti.

This paper deals with the set of adverse to risk decision-makers. For this set a method to check stochastic dominance is proposed. The method works when utility function value is known only on a finite set of points.

Macroeconomic shocks, structural change and real exchange rates: Evidence from historical data

We present empirical evidence on the forces driving real exchange rates in the long-run. Using data from the US, UK and Italy across different exchange rate regimes, we find support for the hypothesis that productivity and fiscal shocks matter. However, in some cases fiscal shocks cause depreciations, likely triggered by the monetary accommodation of fiscal shocks. We also find that the traditional Harrod–Balassa–Samuelson effect of productivity on real exchange rates is reversed in some cases, which confirms the importance of the distributive sector in driving productivity gains.     

Shareholder value efficiency in European banking

This paper advances the studies of [Hughes, J.P., Lang W.W., Mester L.J., Moon C.G., Pagano M.S., 2003. Do bankers sacrifice value to build empires? Managerial incentives, industry consolidation, and financial performance. Journal of Banking and Finance 27, 417–447] by developing a new measure of bank performance which we refer to as “shareholder value efficiency” – a bank producing the maximum possible Economic Value Added (EVA), given particular inputs and outputs, is defined as “shareholder value efficient”. This new efficiency measure is estimated using the stochastic frontier method focussing on the French, German, Italian and UK banking systems over the period 1997–2002 and includes both listed and non-listed banks. We find that European banks are, on average, 36% shareholder value inefficient. Shareholder value efficiency is found to be the most important factor explaining value creation in European banking, whereas cost and profit efficiency only have a marginal influence.
