On the dynamics of inflation persistence around the world

We study the dynamics of inflation persistence in 45 countries for the period 1960–2008 using a recently developed test for multiple changes in persistence, which decomposes the sample information between adjacent I (0) and I (1) periods. We find that: (i) inflation persistence and average inflation tend to fall and rise at the same time; (ii) in some countries there are changes in the level of inflation which do not seem to be related to changes in inflation persistence; (iii) around half of the countries analyzed do not present any burst of I (1) behavior, and hence have stationary inflation throughout; (iv) for the other half, we detect switches of the type I (0) ? I (1) ? I (0), hence, inflation persistence, when it has occurred, has been temporal; and, (v) for about half of the countries in which inflation has presented I (1) behavior, persistent inflation lasted more than a decade. In addition, we find that in the last 50 years there have been mainly two episodes where long bursts of I (1) inflation took place simultaneously among groups of countries. In general, the “Great Inflation” occurred during the seventies and eighties in advanced economies, whereas it occurred during the eighties and nineties in emerging economies, particularly in Latin America.     

Ugo Broggi: a precursor in mathematical economics

The concern for the existence of solution to the Walras - Cassel model is usually dated at the beginning of the 1930s, and one decade later the proof of existence of utility function. Ugo Broggi, however, posed both issues in 1923 and 1919, respectively, and even hinted at modern ways of solving them. He was an outstanding mathematician, a former disciple of David Hilbert and collaborator with the Giornale degli Economisti. Broggi's achievements are also linked to a critical reading of Osorio's treatise on Paretian economics.     

Bentham and Owen on entrepreneurship and social reform

Abstract

Jeremy Bentham invested an important amount of money in New Lanark's cotton mills, which at that time were run by Robert Owen. However, apparently Bentham never took a serious interest in the organisation of such a successful entrepreneurship and new model society, although it seemed to fit in with Bentham's ideas of the entrepreneur (‘projector’) and also with Bentham's ideas on social reform, seeking the greatest happiness of the greatest number. This article explains how Bentham's share in New Lanark came about. It tries to ascertain whether the New Lanark experiment and Owen's ideas fit Bentham's managerial theory and ideas on social reform so as to understand why Bentham did not pay more attention to Robert Owen's practice.     

The evolving role of organisational and personal networks in international market venturing

In a study of 1304 Australian manufacturing industry SMEs, we investigate the relationships among networking (i.e., inter-personal and inter-organisational networks), international market venturing (i.e., export intensity), and family ownership. We find evidence that (1) inter-personal networking and inter-organisational networking positively influence SME international market venturing, but this relationship is contingent on a time lag effect, and (2) family ownership negatively moderates the effect of inter-organisational networking on international market venturing. Implications for managerial practice and public policy are discussed.     

Unbundling tolls from contracts: a new road PPP model

Considerable evidence from different countries has revealed important shortcomings in most road public–private partnership (PPP) models. In this paper a new PPP model is presented that overcomes some of the problems found in PPP road contracts. The new model is based on separating user tolls from the fees paid to PPP contractors and setting up new institutional arrangements to oversee PPPs.     

Developing an alert system for local governments in financial crisis

This article presents a new model which will show whether a local authority is heading for financial trouble. The model is simple for national audit bodies to use and provides an early warning of financial tensions allowing corrective action to be taken before there is a crisis.     

Enterprise Web Accessibility Levels Amongst the Forbes 250: Where Art Thou O Virtuous Leader?

The research team measured the enterprise web accessibility levels of the Forbes 250 largest enterprises using the fully automatic accessibility evaluation tool Sortsite, and presented the compliance of the evaluated websites to WCAG 1.0, WCAG 2.0 and Section 508 accessibility levels. Given the recent attention to organizational leaders having ethical duties towards their dedicated employees, we propose that ‘societal citizenship behaviour’ concerns ethical duties of organizational leaders towards society in general and in particular to those who have less means to assert their needs. In effect, we found enterprise website accessibility levels to be in need of significant improvement. An interpretation of a positive path forward to better enterprise website accessibility levels is put forth based on a focus-group interaction and using BNML—a novel Business Narrative Modelling Language.     

The influence of human resource management in savings bank performance

The aim of this article was to analyse the value of human resources (HR) for competitive advantage and their influence on the firm's performance in the service industry. To achieve our goal, we have first proposed a resource-based framework to discuss the circumstances under which human resources can be a source of competitive advantage. Then, an empirical research was developed in the Spanish savings bank sector to analyse the relationship between HR management and the firm's performance. Our results, suggest that those savings banks which better combine their HR practices to create and to develop a strategic human capital pool have shown better levels of profitability and productivity.     

Multiplicity in general financial equilibrium with portfolio constraints

This paper explores the role of portfolio constraints in generating multiplicity of equilibrium. We present a simple financial market economy with two goods and two households, households who face constraints on their ability to take unbounded positions in risky stocks. Absent such constraints, equilibrium allocation is unique and is Pareto efficient. With one portfolio constraint in place, the efficient equilibrium is still possible; however, additional inefficient equilibria in which the constraint is binding may emerge. We show further that with portfolio constraints cum incomplete markets, there may be a continuum of equilibria; adding incomplete markets may lead to real indeterminacy.
