Implementing the International Public Sector Accounting Standards for consolidated financial statements: facilitators,benefits and challenges

ABSTRACT

Portugal and Spain have reformed their national standards to adapt them to the International Public Sector Accounting Standards (IPSAS). This paper explains the process of implementing the IPSAS for consolidated reporting in the two countries and the advantages and disadvantages which have emerged. The results highlight the role of the IPSAS in improving the quality and use of consolidated financial statements (CFS) and will be of interest to other countries that are intending to implement the IPSAS.     

Nonparametric correlation models for portfolio allocation

This article proposes time-varying nonparametric and semiparametric estimators of the conditional cross-correlation matrix in the context of portfolio allocation. Simulations results show that the nonparametric and semiparametric models are best in DGPs with substantial variability or structural breaks in correlations. Only when correlations are constant does the parametric DCC model deliver the best outcome. The methodologies are illustrated by evaluating two interesting portfolios. The first portfolio consists of the equity sector SPDRs and the S&P 500, while the second one contains major currencies. Results show the nonparametric model generally dominates the others when evaluating in-sample. However, the semiparametric model is best for out-of-sample analysis.     

Cournot equilibrium without apology: Existence and the Cournot inverse demand function

In a multi-commodity framework with absence of wealth effects, we prove the existence of equilibrium for Cournot oligopoly, and that the concept is completely non-ambiguous. We also obtain a uniquely defined endogenous inverse demand function, depending only on the competitive sector.     

Unpacking the interplay between organisational factors and the economic environment in the creation of consumer vulnerability

ABSTRACT

Access to credit is a key enabler of modern life. Yet many consumers face factors beyond their control which sometimes render them unable to borrow from mainstream lenders. This paper documents how firm-related factors determine lending thresholds and shape who is, or is not, a creditworthy customer. The impact of the 2008 economic recession on lending decisions is explored, an aspect that has been insufficiently discussed even though recessions are cyclical events. Drawing on semiotics and using multiple case studies, the study captures not only the groups that were excluded but also the reasons for exclusion. Empirical support is offered for the notion of vulnerability as a fluid state and the role of the timing of decisions as a source of vulnerability is described.     

Tax incentives… or subsidies for business R&D?

We study whether firms’ actual use of R&D subsidies and tax incentives is correlated with financing constraints -internal and external- and appropriability difficulties and investigate whether both tools are substitutes. We compare the use of both policies by SMEs and by large firms and find significant differences both across instruments and across firm size. For SMEs, financing constraints are negatively correlated with the use of tax of credits, while they are positively associated with the likelihood of receiving a subsidy. The use of legal methods to protect intellectual property is positively correlated with the probability of using tax incentives, but not with the use of subsidies. For large firms external financing constraints are correlated with instrument use, but results regarding appropriability are ambiguous. Our findings suggest that (1) direct funding and tax credits are not perfect substitutes in terms of their ability to reach firms experiencing barriers associated to market failures; (2) one size may not fit all in innovation policy when the type or intensity of market failure differs across firm size, and (3) subsidies may be better suited than tax credits to encourage firms, especially young knowledge-based firms, to start doing R&D.     

Spend as I say,not as I do: Children,families and household consumption in different socio‐economic contexts

This article aims at contributing to a body of work about children and families by exploring the importance of socio‐economic context and social capital for understanding the ways in which money is perceived, obtained and used by children. Alleged contrasts in terms of money management, consumption priorities and postponement of gratification, especially among middle and working classes, have already been debated. It seems thus relevant to investigate if these presumable contrasts apply to children and why. Do children from different socio‐economic contexts reveal the traits that have been attributed to their households? To this end, a mixed methods research project was developed involving 245 children attending different primary schools in Portugal—one private school targeted at upper class children and one state‐sponsored school located in a working‐class area. The results revealed significant differences by school and household typology.     

Estimators for the common principal components model based on reweighting: influence functions and Monte Carlo study

The common principal components model for several groups of multivariate observations is a useful parsimonious model for the scatter structure which assumes equal principal axes but different variances along those axes for each group. Due to the lack of resistance of the classical maximum likelihood estimators for the parameters of this model, several robust estimators have been proposed in the literature: plug-in estimators and projection-pursuit (PP) type estimators. In this paper, we show that it is possible to improve the low efficiency of the projection-pursuit estimators by applying a reweighting step. More precisely, we consider plug-in estimators obtained by plugging a reweighted estimator of the scatter matrices into the maximum likelihood equations defining the principal axes. The weights considered penalize observations with large values of the influence measures defined by Boente et al. (2002). The new estimators are studied in terms of theoretical properties (influence functions and asymptotic variances) and are compared with other existing estimators in a simulation study.     

DETERMINANTS OF FOREIGN DIRECT INVESTMENT – A TALE OF NINE THEORETICAL MODELS

Abstract.  This paper presents a review of nine theoretical models of foreign direct investment (FDI). Discussed are early studies of determinants of FDI (1) as well as determinants of FDI based on the neoclassical trade theory (2), ownership advantages (3), aggregate variables (4), the ownership, location and internalization advantage framework (5), horizontal and vertical FDI models (6), the knowledge-capital model (7), diversified FDI and risk diversification models (8) and policy variables (9). From each of the nine theories, the relevant determinants of FDI are derived. Empirical studies indicate the importance of these determinants in the real world. The paper shows that there is not one single theory of FDI, but a variety of theoretical models attempting to explain FDI and the location decision of multinational firms. Therefore, any analysis of determinants of FDI should not be based on a single theoretical model. Instead, FDI should be explained more broadly by a combination of factors from a variety of theoretical models such as ownership advantages or agglomeration economics, market size and characteristics, cost factors, transport costs, protection, risk factors and policy variables.     

Price discovery in the aluminum market

An extended version of the S. Beveridge and C. R. Nelson (1981) decomposition and a latent variable approach are used to examine how the noise content, and therefore the informativeness, of four aluminum prices that have been quoted at various times since 1970—the (now defunct) U.S. producer price, a transactions price reported in a trade journal, and the LME and Comex exchange prices. It was found that the start of aluminum futures trading in 1978 resulted in greater price transparency in the sense that the information content of transactions prices increased. LME prices quickly came to be more informative than published transactions prices. Although the initial Comex aluminum contract failed to attract liquidity and had low information content, the 1999 contract, trading currently, is as transparent as the LME contract. © 2005Wiley Periodicals, Inc.
