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.     

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.

Consuming Alone: Broadening Putnam's “Bowling Alone” Thesis

Despite the popularity of Wi‐Fi technologies and social networks, many residents in developed nations are more socially isolated now than a few decades ago. Applying fuzzy‐set qualitative comparative analysis, using a nationally representative sample in one developed nation this study investigates the relationship between social isolation and advice‐giving and advice‐seeking behaviors with regard to brands or products. This study raises the proposition that people who are socially isolated lack the opportunity to give and seek advice, and, thus, abstain from doing so. Additionally, the study proposes that lacking ability or motivation also represent causal conditions for isolation. The study also investigates consumer behavior outcomes of low advice‐giving and advice‐seeking behaviors; that is, pampering and status buying. The findings from an analysis of an omnibus annual survey of residents in one nation support the propositions that the study proposes from theory and are likely relevant for residents of most developed nations.
