The quarterly national accounts trend–cycle filter versus model–based filters

Abstract. In this paper, we first review the Spanish Quarterly National Accounts (Sqna) trend–cycle filter and give a formula to compute the first component of the filter that corrects an error in the expression that has been used in the Sqna System so far. Then, the results obtained with this last filter are compared to the ones obtained using the Tramo andSeats programs, which apply a model–based methodology. It is concluded that the {sc Sqna} filter presents some problems, such us the generation of spurious cycles, a phase delay, non–efficient initial conditions and larger estimation errors, which can be avoided if model–based filters are used. A Hodrick–Prescott filter with a suitable smoothing parameter is proposed to smooth trend–cycle series that are somewhat volatile and have been obtained with model–based filters. In this way, smooth signals can be obtained that are free of spurious cycles.     

A useful tool for forecasting the Euro-area business cycle phases

Based on a novel extension of existing multivariate Markov-switching models, we provide the reader with a useful tool for analyzing current business conditions and making predictions about the future state of the Euro-area economy in real time. Apart from the Industrial Production Index, we find that the European Commission Industrial Confidence Indicator, which is issued with no delay, is very useful for constructing the real-time predictions.     

An Evaluation of the Value Relevance of Consolidated versus Unconsolidated Accounting Information: Evidence from Quoted Spanish Firms

In this paper we investigate the value-relevance of consolidated versus parent company accounting information. In particular we investigate the value relevance of the minority interest components of net total assets and earnings as currently reported and under the full entity approach to consolidated reporting. An Edwards-Bell-Ohlson valuation framework is used to generate results. By this means we cast light on the suitability of accounting regulation being developed based upon the entity or parent company theories of consolidation. We carry out the analysis in the Spanish context and the sample contains 474 observations of non-financial firms quoted in the Madrid Stock Exchange for the period 1991–97. The results from this analysis not only have domestic relevance but provide guidance of a more international nature relating to the impact of group definition, concepts of control and the most value relevant method of consolidated disclosure. The results show that, from a valuation perspective, consolidated information dominates non-consolidated, or parent company, information. However, neither the currently reported minority interest components of net total assets and earnings, nor their values under the full equity method of consolidation, are found to be value relevant. These results raise the question of whether group definitions based on the equity theory of consolidation are the most useful to investors.     

A city of trades: Spanish and Italian immigrants in late-nineteenth-century Buenos Aires,Argentina

The city of Buenos Aires in the 1890s is an extreme case in immigration history since the native workers accounted for less than one-third of the labour force. In this paper, we look at the labour market performance of Argentineans vis-à-vis the largest two immigrant groups, Italians and the Spaniards. We find that, on average, Argentineans enjoyed higher wages, but workers specialised in particular occupations by nationality. Immigrants clustered in occupations with lower salaries. Despite higher literacy levels and the language advantage, Spaniards did not outperform Italians in earnings. Ethnic networks facilitated the integration of immigrants into the host society and played a role in the occupation selection of immigrants. Our results suggest that Italian prosperity in Buenos Aires was not based on superior earnings or skills but on older and powerful networks.     

The welfare effects of the allocation of airlines to different terminals

Many airports around the world have recently built, rebuilt or are in the process of constructing new terminals. Incumbent airlines and new entrants must be allocated to the new and old facilities. When spaces at airport terminals are directly allocated, the allocation should be done by taking into account the implications for airlines’ competition and social welfare, given the airlines’ network configuration. We use a theoretical model in which two airlines compete in prices with differentiated products for a given network structure. The model shows that, in general, if airlines are allocated to different terminals, the level of competition is reduced, the ticket prices are higher and the consumer surplus and social welfare are lower. Only in some routes, and under certain conditions on the market size, ticket prices may be lower.

El desempeño económico financiero y responsabilidad social corporativa Petrobrás versus Repsol

Alterations in the institutional environment, as a result of the markets integration process and the consequent alterations in stakeholders’ conduct are one of the important vectors of changes in companies’ behavior. In that context, in addition to their yields those companies happen to worry about their attitudes in relation to social and environmental factors. Thus, the corporate social responsibility (CSR) is seen as one more strategy to maintain or increase their income and to harness the enterprise development. The main purpose of this study is the verification of the existing relation between Social Responsibility and the economic and financial performance of two companies in the business of Petroleum, Gas and Bio-combustibles. The investigation was based on a comparison of social-environmental practices developed by Petrobras S/A (Brazil) and Repsol S/A (Spain). For the purpose of verification of the relation between social-environmental performance and the economic-financial one, a linear regression analysis was carried out.
