Currency substitution and the stability of the Italian demand for money before the entry into the monetary union, 1972–1998

A money demand function for M2 is estimated for Italy for the period 1972–1998 within an error correction framework. This period has been characterized by major structural changes in the Italian financial system and by major changes in monetary policy. This study takes these changes into account. Moreover, currency substitution, especially between Italy and Germany is incorporated into the model. By accounting for structural breaks and currency substitution a stable money demand function can be found.Financial support from the Deutsche Forschungsgemeinschaft, SFB 373, is gratefully acknowledged.

A customer’s utility measure based on the reliability of multi-state systems

The main focus of this paper is on the development of utility measures for dynamic multi-state systems that have M + 1 discrete states of working efficiency. To develop the utility measures for multi-state systems, we assume that the degradation of the multi-state systems follows a non-homogeneous semi-Markov process together with a backward recurrence time process and that the system can directly degrade into any lower state. The measure considers the immediate utility derived from the state of the system occupancy and the utility due to the system survival expectations derived from its reliability. Moreover, in order to measure the customer’s cumulative utility, the discounted non-homogeneous continuous time semi-Markov process with rewards is implemented. In such a way, the higher order moments of the reward process can be evaluated and then, in particular, the expectation and the standard deviation of the consumer’s accumulated discounted utility. These statistic indices are useful both to the industry in order to compare different system designs offered by the market and to the market itself, in order to know the customer’s utility deriving from the goods she/he consumes. Finally, a numerical example shows the possibility of implementing the model in real-life problems.     

The Return of Keynesian Economics: A Contribution in the Spirit of John Cornwall's Work

This paper assesses the recent interest for Keynesian economics in academia and policy-making circles. It examines the main features of Keynesian economics vis-à-vis neoclassical economics, before presenting the three-equation New Consensus Macroeconomics (NCM) model and its Keynesian roots. Drawing on the work of John Cornwall, the main conclusion of the paper is that the most important criticisms of the model are related to the acceptance of the axiom of independence between aggregate supply and aggregate demand by proponents of the NCM view.     

The new public corruption: Old questions for new challenges

This paper focuses on corruption in public procurement. It describes the contemporary face of corruption by investigating the role of public accountability in the fight against corruption. The paper describes a specific episode of corruption relative to the awarding of government contracts for big events, such as the celebration of the 150th anniversary of Italian unification. Relying on the philosophical insights of Rousseau, Popper, Kant and others, the study suggests the need for enabling a democratic control and constructing a public ethics for the common good.     

Endogenous Money: An Analytical Approach

The paper proposes a constructive interpretation of the Post Keynesian debate between horizontalists and structuralists. Both approaches defend an endogenous money theory, but they discriminate between different analyses of the credit market and the reserve market. A more general model encompassing both approaches is presented here and some of its implications are discussed.     

Delegating management to experts

Owners of property and assets frequently delegate decisions about operating and maintaining their property to managers who are better informed about local market conditions. We analyze how owners optimally contract with managers who vary in their expertise at prescribing service. We show that the most expert managers offer the greatest variation in operating recommendations. Owners benefit from dealing with experts provided they contract sequentially, whereby terms are negotiated gradually as the manager acquires information.     

“Mr Keynes and the ‘Classics’” Again: A Methodological Enquiry

Keynes is usually interpreted as proposing, or intending to propose an original theory of employment and income. However, this paper shows that Keynes was actually proposing more than a theoretical alternative. He saw himself breaking away from the ‘Classics’ at the connected levels of theory and methodology. This paper thus argues that modern economists going back to the old story of the relation between Mr. Keynes and the ‘Classics’ can learn something about several controversial issues in macroeconomics and methodology like for instance the role of experiments and formal arguments in economics.The paper is the development of a chapter in my Ph.D. thesis and has greatly benefited from discussion with Mark Blaug, Anna Carabelli, Bill Gerrard, Marc Lavoie, Tony Lawson, Roy Rotheim, and especially Geoff Harcourt and Malcolm Sawyer. Errors and omissions are, of course, solely my responsibility. A first draft of the paper was presented at the UK Autumn HET Conference (Glasgow Caledonian University, September 1999) and the AISPE Conference (University of Florence, September 1999). Finally, the paper was completed when I was visiting Research Professor at the Economics Department and C-FEPS, University of Missouri Kansas City (UMKC), Kansas City (USA) and Visiting Fellow at Clare Hall College and CCEPP, University of Cambridge, Cambridge (UK). I would like to express appreciation to members of those institutions for providing a stimulating and pleasant working environment.
