Does public capital affect private sector performance?: An analysis of the Spanish case, 1964–1988

Abstract The possible influence of public capital accumulation on private sector economic performance is examined using Spanish data for the 1964–1988 period. To do this, a simple aggregate production function for private output, including government-owned capital as a separate factor, is estimated by cointegration techniques. The results tend to support the view that the stock of public capital plays an important role in affecting private sector productivity.

Exchange-rate forecasts with simultaneous nearest-neighbour methods: evidence from the EMS

Abstract In this paper we extend nearest-neighbour predictors to allow for information content in a wider set of simultaneous time series. We apply these simultaneous nearest-neighbour (SNN) predictors to nine EMS currencies, using daily data for the 1st January 1978–31st December 1994 period. When forecasting performance is measured by Theils U statistic, the (nonlinear) SNN predictors perform marginally better than both a random walk and the traditional (linear) ARIMA predictors. Furthermore, the SNN predictors outperform the random walk and the ARIMA models when producing directional forecasts.When formally testing for forecast accuracy, in most of the cases the SNN predictor outperforms the random walk at the 1% significance level, while outperforming the ARIMA model in three of the nine cases. On the other hand, our results suggest that the probability of correctly predicting the sign of change is higher for the SNN predictions than the ARIMA case.

Chaotic behaviour in exchange-rate series : First results for the Peseta--U.S. dollar case

Abstract We test for the presence of deterministic chaos on daily data for the (spot and forward) Spanish Peseta–U.S. Dollar exchange rates. The finding of a chaotic behaviour in the series allows us to make short-run predictions which in general outperform those from the random walk model.

Modelling the Linkages between Us and Latin American Stock Markets

This paper examines the linkages between US and Latin American stock markets during the 1995-2002 period using recently developed cointegration techniques that allow for structural shifts in the long-run relationship. Results suggest that when conventional cointegration tests are applied, a long-run relationship is found only in the cases of Brazil and Mexico for the Dow Jones (DJ) index, and in the case of Brazil for the Standard and Poors 500 (SP500) index. In contrast, if the possibility of structural breaks is introduced, strong evidence is found in favour of such a relationship between the Argentine, Chilean and Venezuelan indices and the DJ index after the 1998 financial turmoil, and between the Brazilian and Mexican indices and the DJ index before such turbulence, while some marginal cointegration is detected between the Mexican and DJ indices from February 1998. Additionally, evidence is found of a cointegrating relationship between the Argentine, Chilean and Mexican indices and the SP500 index from August 1998, April 1999 and October 1999, respectively, and between the Brazilian and the SP500 indices before November 1997, as well as some marginal cointegration between the Mexican and SP500 indices before October 1999. The results suggest that the gains from international diversification for investors with long holding periods is limited.

HERMIN: A macroeconometric modelling framework for the EU periphery

Abstract The need to analyse the effects of EU regional policy required the construction of new models with an orientation towards the problems being experienced in the periphery. We explain the justification for, and nature of, the new modelling framework, giving a brief overview of the economies of the four objective 1 countries, focusing on issues that are particularly relevant to the targets of regional policy. We explore the implications of the stylized facts for model design in the periphery. Finally, we summarize the main common features of the HERMIN modelling approach, and illustrate where key choices need to be made in the light of national specificities.

Asymmetry in the EMS: New evidence based on non-linear forecasts

Abstract In this paper we provide new evidence on the hypothesis of German leadership and asymmetric performance in the EMS, in the framework of causality tests, using daily data. Given the evidence about non-linearity in financial series, we propose applying non-linear forecasting methods based on the literature on complex dynamic systems. Our analysis covers nine countries, and the sample period runs until 30 April 1998, so including the more recent events in the EMS history. A comparison of our results with those obtained from standard linear econometric techniques leads us to conclude that inference on causality based on our non-linear predictors would be preferable to that based on the standard linear approach.

Causality and Contagion in Peripheral EMU Public Debt Markets: A Dynamic Approach

Our research aims to analyze the causal relationships in the behavior of public debt issued by peripheral member countries of the European Economic and Monetary Union (EMU), with special emphasis on the recent episodes of crisis triggered in the eurozone sovereign debt markets since 2009. With this goal in mind, we make use of a database of daily frequency of yields on 10-year government bonds issued by five EMU countries (Greece, Ireland, Italy, Portugal and Spain), covering the entire history of the EMU from its inception on 1 January 1999 until 31 December 2010. In the first step, we explore the pair-wise causal relationship between yields, both for the whole sample and for changing subsamples of the data, in order to capture the possible time-varying causal relationship. This approach allows us to detect episodes of contagion between yields on bonds issued by different countries. In the second step, we study the determinants of these contagion episodes, analyzing the role played by different factors, paying special attention to instruments that capture the total national debt (domestic and foreign) in each country.

Assessing the credibility of a target zone: evidence from the EMS

This paper provides some new evidence on the credibility of the Exchange Rate Mechanism (ERM) of the European Monetary System (EMS). The study differs from previous research in the literature in three main respects. First, the main contribution is the use of several credibility indicators, some of which have never been applied before to all of the currencies under study. This allows one to strengthen the results obtained in this paper. Second, a longer period than that of previous studies is analysed, covering the complete EMS history. Third, a comparison has been made of the prediction qualities of the different indicators, in order to explore their ability to capture the main ERM events (realignments, changes in the fluctuations bands and speculative pressures). Fourth, the indicators are applied to the experience of the new, modified ERM linking the currencies of non-euro area Member States to the euro, showing the relevance of this approach in the near future with the enlargement of the European Union.

An update on EMU sovereign yield spread drivers in times of crisis: A panel data analysis

We empirically investigate the determinants of EMU sovereign bond yield spreads with respect to the German bund. Using panel data techniques, we examine the role of a wide set of potential drivers. To our knowledge, this paper presents one of the most exhaustive compilations of the variables used in the literature to study the behaviour of sovereign yield spreads and, in particular, to gauge the effect on these spreads of changes in market sentiment and risk aversion. We use a sample of both central and peripheral countries from January 1999 to December 2012 and assess whether there were significant changes after the outbreak of the euro area debt crisis. Our results suggest that the rise in sovereign risk in central countries can only be partially explained by the evolution of local macroeconomic variables in those countries. Besides, without exception, the marginal effects of sovereign spread drivers (specifically, the variables that measure global market sentiment) increased during the crisis compared to the pre-crisis period, especially in peripheral countries.

Price Convergence in the European Union

This study investigates the relationship between market integration and price convergence in international markets. Using a panel data set of consumer price indices (general and by groups and classes), it examines how European market integration has affected cross-country dispersion in the European Union.
