A general framework for the macroeconomic analysis of monetary unions
(2001) Bajo Rubio, Óscar; Díaz Roldán, Carmen; Economía; Ekonomia
The objective of this paper is to develop a general framework for the macroeconomic modelling of monetary unions, which could be useful for policy analysis, as well as for teaching purposes. Our starting point will be the standard two-country Mundell-Fleming model with perfect capital mobility, extended to incorporate the supply side, and modified so that the money market is common for two countries forming a monetary union. The model is presented in two versions: for a small and a big monetary union, respectively. After solving each model, we will derive multipliers for monetary, real (i. e., demand-side), supply, and external shocks, paying a special attention to the distinction between symmetric and asymmetric shocks. A graphical analysis is also provided.

¿Es sostenible el sistema de Seguridad Social en España? Situación actual y perspectivas
(1999) Montero Muñoz, María; Da Rocha Álvarez, José M.; Bajo Rubio, Óscar; Economía; Ekonomia
En este trabajo se analiza la sostenibilidad del sistema de la Seguridad Social en España. Para ello se examinan los principales componentes de los ingresos y gastos del sistema que han caracterizado su evolución en los últimos años, así como aquellos factores que más han contribuido a la actual configuración de la estructura de la población de España, como son la evolución de la esperanza de vida y de la tasa de la natalidad. La evidencia que ofrecen los datos, unida a los resultados de los trabajos disponibles sobre el tema, llevan a poner en cuestión la viabilidad futura del sistema si se mantienen las circustancias actuales.

Simulating the effects of the European singles market: a CGE analysis for Spain
(2005) Bajo Rubio, Óscar; Gómez Gómez-Plana, Antonio; Economía; Ekonomia
In this paper we provide an empirical assessment of two of the measures proposed in the context of the European Single Market, namely, easing the provision of domestic and foreign services, and modifying the rules of public procurement, for the case of Spain. We build and simulate a computable general equilibrium (CGE) model, which incorporates three particular features: (i) increasing returns to scale and a noncompetitive price rule; (ii) sectoral export demand functions; and (iii) equilibrium unemployment according to a matching function approach.

Inequality foundations of concentration measures: an application to the Hannah-Kay indices
(1999) Bajo Rubio, Óscar; Salas, Rafael; Economía; Ekonomia
In this paper we provide a connection between concentration and inequality by showing that the inequality measures consistent with the whole class of Hannah-Kay concentration indices are the general entropy inequality indices. We isolate the inequality component underlying the concentration measures, obtaining an explicit additive decomposition of the change in concentration into the change in its two components: inequality and the number of firms. This relationship proves to be valid for the whole class of Hannah-Kay concentration indices, and embodies as particular cases other previously found in the literature. Finally, our proposed decomposition is shown by means of an empirical example, which illustrates the sources of a change in sectoral concentration between two points in time.

On the insurance function of fiscal policy in a monetary union
(2000) Bajo Rubio, Óscar; Díaz Roldán, Carmen; Economía; Ekonomia
In this paper we first review the available literature on the degree of insurance against shocks, provided by the central budget in the federal systems already existing. Next, we discuss the main points raised on the debate about the implementation of an automatic mechanism designed to cope with country-specific shocks in a monetary union, and present a specific proposal of such a mechanism.

¿Existe un efecto Fisher en el largo plazo? Evidencia para la economía española, 1962-1996
(1998) Bajo Rubio, Óscar; Esteve, Vicente; Economía; Ekonomia
En este trabajo se contrasta empíricamente el cumplimiento del efecto Fisher a largo plazo para el caso español, utilizando datos trimestrales para el periodo 1962-1996. Para ello se utilizan nuevas técnicas de raíces unitarias y cointegración, donde se tienen en cuenta explícitamente la presencia de posibles cambios estructurales en la tendencia de las series. Los resultados son favorables a la existencia de un efecto Fisher parcial en el largo plazo, con una transición al tipo de interés nominal de aproximadamente un tercio por cada punto de incremento en la tasa de inflacción.

Foreign direct investment and trade: a causality analysis
(1999) Bajo Rubio, Óscar; Montero Muñoz, María; Economía; Ekonomia
We analyse in this paper the relationship between outward FDI and exports, with Spanish quarterly data for the period 1977-1992. The empirical methodology makes use of Granger-causality tests in a cointegration framework, where the order of lags for each variable has been selected by means of Hsiao’s sequential approach. The tests have been performed both in a bivariate and multivariate setting, in the latter case including as additional variables a proxy for world income and the relative price of exports. Since cointegration between outward FDI and exports was found, error-correction mechanisms under three alternative specifications were included, which allowed us to discriminate between short- and long-run Granger-causality. Our results point to the existence of long-run Granger-causality from outward FDI to exports, according to a complementary relationship, for the Spanish case during the period of analysis.

Asymmetry in the EMS: new evidence based on non-linear forecasts
(2000) Bajo Rubio, Óscar; Sosvilla Rivero, Simón; Fernández Rodríguez, Fernando; Economía; Ekonomia
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.

An industry analysis of foreign direct investment in Spanish manufacturing, 1986-1992
(1998) Bajo Rubio, Óscar; López Pueyo, Carmen; Economía; Ekonomia
This paper tries to analyse the main features associated with foreign direct investment (FDI) directed to Spanish manufacturing, both across industries and through time. To this end, we will make use of a data set on 20 manufacturing industries for the years 1986-1992, in which Spanish manufacturing industry experienced a sustained period of growth. Then, a relative FDI measure will be related to several industry indicators, as well as to some macroeconomic variables, which will allow us to obtain a general characterization of FDI in Spanish manufacturing over that period.

A further generalization of the Solow growth model: the role of the public sector
(1999) Bajo Rubio, Óscar; Economía; Ekonomia
We develop in this paper an augmented version of the Solow (1956) growth model, including the role of government. The model leads to a non-monotonic relationship between the rate of growth of per capita output and government size, generalizing previous results by Barro (1990) to the case in which returns to scale to private factors are not constant.
