TRUST AND VIRTUAL DISTRICTS: EVIDENCE FROM THE MILAN INTERNET EXCHANGE

Peering decisions between Internet Service Providers (ISPs) contain substantial non‐measurable aspects requiring trust and informal cooperation among peering partners. We study whether virtual districts are observed between Internet peers. Our empirical analysis of the bilateral peering decisions at the Milan Internet Exchange confirms that these decisions are significantly influenced by: travel time either between ISPs' headquarters or towards the exchange—a proxy for distance, bandwidth—a proxy for size, and European connectivity. Proximity still plays a role in reducing the transaction costs of monitoring and punishing deviant behavior within an industry where trust is essential for Internet universal connectivity.     

Value stream mapping implementation in the third sector

An analysis of the development of non-profit organizations highlights critical issues related to the efficiency and strategic capacity of many organizations. To do this, it is necessary to use management models that combine the effectiveness of social solidarity with acceptable levels of efficiency. This study focuses on the application of Value Stream Mapping (VSM) to reorganize the work placement service in one of Italy??s major third sector organizations. A telephone survey, administered to 184 diocesan counseling services, provided an exhaustive overview of the macro-environment and the work placement service features. The process re-engineering is dealt with by an interdisciplinary approach. Implementing the Allison and Kaye model provides an approach specific to non-profit organizations. Furthermore, the use of VSM in the strategic planning enriches the model itself and provides a practical and pragmatic approach typical of re-engineering that focuses on the organization??s objectives. VSM allows the identification of the critical points in the value flow chain, and the suggested actions support the development of the work placement service.     

Sustainable Rates of Return for Milk Quotas in Ontario

This paper utilizes the capital asset pricing model, together with available econometric estimates of the cost function of Ontario dairy farms, to estimate rates of returns for three types of milk quotas. The estimated rates follow the trend of the interest rate in the economy, and the rate of return on fluid milk quota is higher than the rate of return on industrial milk quotas. Cet article utilise un modèle de formation des prix des actifs, avec des estimées économetriques de la fonction de coûts des producteurs laitiers de ?Ontario, pour estimer les taux de retour associés avec trois differents types de quotas laitiers. Les taux estimés suivent la même tendence que le taux ?intérêt dans ?économie, et le taux de retour du quota pour le lait fluide est plus elevée que les taux de retour du quotas pour le lait industriel.     

Differentiated oligopolistic markets with concave cost functions via Ky Fan inequalities

A Nash–Cournot model for oligopolistic markets with concave cost functions and a differentiated commodity is analyzed. Equilibrium states are characterized through Ky Fan inequalities. Relying on the minimization of a suitable merit function, a general algorithmic scheme for solving them is provided. Two concrete algorithms are therefore designed that converge under suitable convexity and monotonicity assumptions. The results of some numerical tests on randomly generated markets are also reported.     

Models to date the business cycle: The Italian case

The problem of dating the business cycle has recently received many contributions, with a lot of proposed statistical methodologies, parametric and non-parametric. In general, these methods are not used in official dating, which is carried out by experts, who use their subjective evaluations of the state of economy. In this work we try to apply some statistical procedures to obtain an automatic dating of the Italian business cycle in the last 30 years, checking differences among various methodologies and with the ISAE chronology. The purpose of this exercise is to verify if purely statistical methods can reproduce the turning points detection proposed by economists, so that they could be fruitfully used in official dating. To this end parametric as well as non-parametric methods are employed. The analysis is carried out both aggregating results from single time series and directly in a multivariate framework. The different methods are also evaluated with respect to their ability to timely track (ex post) turning points.     

Marx and Sraffa: A Comment on Gehrke and Kurz

This comment focuses on the assertion by Gehrke and Kurz (2018) that the origin of the equations which formed the backbone of Sraffa’s Production of Commodities by Means of Commodities is not related in any way to Marx, and particularly Marx’s reproduction schemes, as argued by the late Giorgio Gilibert and myself. This comment argues that the 2018 article by Gehrke and Kurz makes significant—but unacknowledged—retreats from positions previously presented by the authors, and that the relevance of Marx and his reproduction schemes for the origin of Sraffa’s (1960) work for Production of Commodities is beyond reasonable doubt.     

Expectations and systemic risk in EMU government bond spreads

This paper explores the determinants of 10-year sovereign bond spreads over the German Bund benchmark in the Euro Zone from 2000 to 2013, relying on cross-country quarterly data panel analysis. The paper focal point is the role of contagion and euro break-up risks in widening the sovereign bond yield differentials among EU member countries. Using a novel synthetic index capable of monitoring the sustainability of currency unions, the paper finds that market expectations of a euro’s break up and contagion from Greece were fundamental drivers of sovereign risk premia in peripheral countries.     

INTEREST RATE PEGS,WEALTH EFFECTS AND PRICE LEVEL DETERMINACY

This paper analyses the issue of price level determinacy in an optimizing general equilibrium model with overlapping generations. It is shown that under a pure interest rate peg wealth effects rule out nominal indeterminacy but give rise to multiple equilibria.     

The characteristics of a monetary economy: a Keynes-Schumpeter approach

Mainstream monetary theory considers money only as an instrumentmeant to facilitate trading without having any effect on incomeor on the evolution of the economic system. The aim of thispaper is to elaborate a monetary theory capable of supportingthe thesis of money non-neutrality based on the arguments developedby Keynes and Schumpeter. The synthesis of the theories of thesetwo great economists will be formulated starting from the twopoints which are common in the views of Keynes and Schumpeter.First, in contrast with mainstream theory, Keynes and Schumpeterstate that the diffusion of a fiat money induces a radical modificationinto the way in which the economic system works. Second, whenKeynes and Schumpeter describe the reasons why money and financialaggregates are not neutral, they highlight the fundamental roleof the credit market and of banks; in contrast with the mainstreamtheory, they do not consider the credit market as the mirrorimage of the goods market.
