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.

Anchoring the yield curve using survey expectations

The dynamic behavior of the term structure of interest rates is difficult to replicate with models, and even models with a proven track record of empirical performance have underperformed since the early 2000s. On the other hand, survey expectations can accurately predict yields, but they are typically not available for all maturities and/or forecast horizons. We show how survey expectations can be exploited to improve the accuracy of yield curve forecasts given by a base model. We do so by employing a flexible exponential tilting method that anchors the model forecasts to the survey expectations, and we develop a test to guide the choice of the anchoring points. The method implicitly incorporates into yield curve forecasts any information that survey participants have access to—such as information about the current state of the economy or forward‐looking information contained in monetary policy announcements—without the need to explicitly model it. We document that anchoring delivers large and significant gains in forecast accuracy relative to the class of models that are widely adopted by financial and policy institutions for forecasting the term structure of interest rates.     

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.     

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.
