Public employment and compensation reform: the role of social dialogue and structural measures

This paper compiles and compares recent and past measures introduced to contain the public wage bill in a number of emerging and advanced economies to assess their effectiveness in bringing down expenditure in a sustained way. In the aftermath of the financial crisis, a number of countries have approved measures on the wage bill as part of fiscal consolidation efforts. These recent episodes are compared to past cases implemented in advanced economies over the period 1979–2009. Findings suggest that public wage bill consolidation episodes pre- and post-2009 are similar in many respects. Moreover, typically countries that were able to achieve more sustained reductions in the wage bill have implemented to larger extent structural measures, and/or these measures were accompanied with substantial social dialogue and consensus.     

Efficient selection of copper sales contracts for small- and medium-sized mining

The purpose of this study is to generate efficient policies for the selection and postponement of copper sales contracts by a mining company. To do so, it uses a two-stage stochastic programming model that determines solutions considering different contract types, random prices, and risk aversion. The results show how it is possible for the selection to involve the lowest risk possible for different revenue levels required. During a period of high price volatility, an efficient solution may deliver an increase in monthly revenue of US$210,000 for a mining company that produces 50,000 tons per year, without any additional risk.     

The impact on the pricing process of costly active management and performance chasing clients

One of the necessary features of markets to produce efficient pricing is competition between information-based investors who quickly impound new information into price. However, a significant proportion of funds invested in today’s equity markets are in the hands of managers who pursue a style that utilises little or none of the available information. We simulate such a market where the funds are being managed using the following three investment styles: fundamental, momentum and index. We confirm that the major pricing anomalies that have been highlighted previously in the literature are a natural consequence of competition between managers utilising these three investment styles. More importantly, we show that this situation is unlikely to change as long as markets continue to be dominated by costly active managers with clients who pursue outperformance.     

Capitalization of R&D costs and earnings management: Evidence from Italian listed companies

The capitalization of research and development (R&D) costs is a controversial accounting issue because of the contention that such capitalization is motivated by incentives to manipulate earnings. Based on a sample of Italian listed companies, this study examines whether companies' decisions to capitalize R&D costs are affected by earnings-management motivations. Italy provides a natural context for testing our hypothesized relationships because Italian GAAP allows for the capitalization of R&D costs. Using a Tobit regression model to test our hypotheses, we show that companies tend to use cost capitalization for earnings-smoothing purposes. The hypothesis that firms capitalize R&D costs to reduce the risk of violating debt covenants is not supported.     

Anonymity in nonatomic games

This paper purpose is twofold. First, it offers a critical review of the proofs of existence of pure strategy Nash Equilibria in nonatomic games. In particular, it focuses on the alternative ways of formalizing the critical assumption of anonymity. Second, the paper proves the existence of pure strategy Nash Equilibria by relaxing anonymity and allowing instead for “limited anonymity” (i.e. players’ decisions depend on the average strategy of a finite number of players’ subsets and not on the average strategy of the whole set of players).

The Effect of Specialisation on Banks' Efficiency: An International Comparison

This study analyses the effects of specialisation on the cost efficiency of a set of banking systems of the European Union over the period 1992–1998. Unlike in the established literature in which specialisation differences are not considered, in this paper cost inefficiencies are decomposed into two different components: the first is related to the inefficiency associated with the composition of specialisations in each banking system and the second is related to specific inefficiencies of banks within their specialisation. The results show the existence of high cost inefficiencies. However, the intra‐specialisation inefficiencies indicate that the inefficiencies of the European banking systems are much smaller when the effect of productive composition (specialisation) is discounted. This effect is much more evident in those banking systems specialised in the more costly types of business (retail banking) because their composition inefficiency is higher.     

Modelling low income transitions

We examine the determinants of low income transitions using first‐order Markov models that control for initial conditions effects (those found to be poor in the base year may be a non‐random sample) and for attrition (panel retention may also be non‐random). The model estimates, derived from British panel data for the 1990s, indicate that there is substantial state dependence in poverty, separate from persistence induced by heterogeneity. We also provide estimates of low income transition rates and lengths of poverty and non‐poverty spells for persons of different types. Copyright © 2004 John Wiley & Sons, Ltd.
