Increased coordination in public transport—which mechanisms are available?

After several years of New Public Management reforms within public transport, coordination seems to receive increased attention. With examples of actual as well as suggested changes taken from Denmark, Sweden and the UK the aim of the article is to analyse and classify the mechanisms utilized and suggested to increase coordination between core stakeholders within passenger railway services and bus services. Four distinctive mechanisms of coordination are suggested, namely organisational coordination, contractual coordination, partnership coordination and discursive coordination. Each coordination mechanism has its strengths and failures. The article also debates to what extent the mechanisms conflict with three core characteristics of New Public Management: Unbundling of the public sector into corporatized units; more contract-based competitive provision; and greater emphasis on output controls.     

Regimen changes and duration in the European Monetary System

This article examines the regime changes in the Exchange Rate Mechanism (ERM) of the European Monetary System (EMS), applying the duration model approach to weekly data of eight currencies participating in the ERM, covering the complete EMS history. When using the non-parametric (univariate) analysis, it was found that for those regimens with long durations, the ERM would have been relatively stable, while for the (more common) regimes associated with short durations would have been more unstable. The probability of maintaining a certain regime is estimated to be 0.685. When applying a parametric (multivariate) analysis to investigate the role of other variables in the probability of a regime change, it is concluded that the interest rate differential with Germany and the magnitude of the realignment would have negatively affected the duration of a given regime, while credibility would have positively influenced such duration. Finally, when distinguishing between groups of currencies, it is observed that those in the core are more stable than those in the periphery, obtaining evidence against equality of survival functions among these groups of currencies.     

TECHNICAL NOTE A MODIFIED EOQ MODEL WITH TEMPORARY SALE PRICE DERIVED WITHOUT DERIVATIVES

Most previous works applied differential calculus to derive optimal solutions for economic ordering policy. The formulations are suggested in this short note to show that optimal solutions can be derived algebraically without using differential calculus to treat the EOQ model with a temporary sale price.     

Implementation of Four Models for Outstanding Liabilities in Winbugs: A Discussion of a Paper by Ntzoufras and Dellaportas

Abstract

Ntzoufras and Dellaportas (2002) described four models for outstanding claim amounts of the “reported but not settled” variety. Two of the models incorporated claim-counts data in addition to the claim amounts themselves in order to add a hierarchical stage in the usual log-normal and state-space models. The purpose of this discussion is to describe how the models presented in Ntzoufras and Dellaportas may be implemented using WinBUGS. The use of WinBUGS to implement the Bayesian analysis of a number of other actuarial models was considered by Scollnik (2001).     

A Note on Laurence Seidman’s Article

Mihail Manoilescu was among the foremost intellectual figures of the interwar period in Romania. He was known as a politician and central banker, as well as an economist. From the very beginning of his theoretical and practical career, or at least from the late 1920s onward, Manoilescu’s ideas and theories (especially his corporatist theory) were marked by clear continuity and consistency based on the theory of protectionism grounded on productivity differences. By developing his model — an alternative to the theory of comparative advantage — Manoilescu endeavored to show the need for protectionist measures to promote the development of peripheral countries. His defense of protectionism is usually presented as clumsy and founded on an incorrect method, even if he is often recognized as the forerunner of the theory of unequal exchange and the dependency theory. Few scholars note the similarity of Manoilescu’s theory with Karl Marx’s labor theory. This paper contributes to validating Manoilescu’s conclusions, the soundness of which we test here by reconstructing the theory from a Marxian perspective. A reconstruction of this type offers new possibilities of evaluating his theory and a better understanding of its contributions and limitations.     

The Effects of Average Norm Model Regulation: The Case of Electricity Distribution in Sweden

Following the reform of energy sectors, some countries have used engineering norm models in incentive regulation of network utilities. In 2003, Sweden adopted this approach to regulation of electricity distribution networks. This paper examines whether the norm models represent the real networks and create incentives for performance improvement. We analyse data from 138 network concession holders between 2000 and 2007. The results show that norm models are not adequate representations of real networks. Also, utilities that perform better than their norm models tend to behave opportunistically. Finally, we find that private utilities respond more strongly to incentives.
