La financiación del sistema de seguridad social en España: efectos dinámicos de una posible reforma

[spa] Este artículo analiza los efectos de dos posibles reformas en la financiación del actual sistema de Seguridad Social en España, y cuantifica los efectos de dichas reformas sobre los principales agregados macroeconómicos. El tipo de reformas que se analizan son la sustitución del actual régimen de financiación de cotizaciones, por imposición directa e indirecta, y los efectos de variaciones en plazo de cálculo de las pensiones de jubilación. Para este proposito se construye un modelo de equilibrio general de generaciones sucesivas con agentes heterogéneos, calibrado para obtener resultados cuantitativos para el caso español.

La participación en los órganos sociales de las cooperativas en España

En los estudios de las organizaciones domina la investigación relacionada con la gestión. Sin embargo,poco a poco, el análisis de la participación y la implicación activa de los socios en los órganos de gobierno de las organizaciones democráticas va creando su propio espacio de interés. Los directivos empiezan a descubrir que la implicación del socio en la sostenibilidad económica proporciona ventaja competitiva. En el caso del cooperativismo de consumo en España, es este artículo se presentan los resultados de un estudio encargado por Hispacoop al Centro de Investigación de Economía y Sociedad (cies, 2010) de la Universidad de Barcelona, siendo esta una primera aproximación al estudio de la participación del socio en el gobierno de diez cooperativas de consumo que operan en el mercado español. Palabras clave: consumo, cooperativas, gestión, gobierno organizacional, procesos de participación.

Fiscal policy and interest rates: the role of financial and economic integration

It is commonly believed that a fiscal expansion raises interest rates. However, these crowding out effects of deficits have been found to be small or non-existent. One explanation is that financial integration offsets interest rate differentials on globalised bond markets. This paper measures the degree of integration of government bond markets, using spatial modelling techniques to take this spillover on financial markets into account. Our main finding is that the crowding out effect on domestic interest rates is significant, but is reduced by spillover across borders. This spillover is important in major crises or in periods of coordinated policy actions. This result is generally robust to various measures of cross-country linkages. We find spillover to be much stronger among EU countries.

Sustainability of EU fiscal policies. A panel test

The fiscal policy rule implicit in the Stability and Growth Pact, has been rationalised as a way to ensure that national fiscal policies remain sustainable within the EU, thereby endorsing the independence of the ECB. We empirically examine the sustainability of European fiscal policies over the period 1970-2001. The intertemporal government budget constraint provides a test based on the cointegration relation between government revenues, expenditures and interest payments. Sustainability is analysed at both the national level and for a European panel. Results show that European fiscal policy has been sustainable overall, yet national experiences differ considerably.

Fiscal sustainability across government tiers: an assessment of soft budget constraints

This paper analyses how fiscal adjustment comes about when both central and sub-national governments are involved in consolidation. We test sustainability of public debt with a fiscal rule for both the federal and regional government. Results for the German Länder show that lower tier governments bear a relatively smaller part of the burden of debt consolidation, if they consolidate at all. Most of the fiscal adjustment occurs via central government debt. In contrast, both the US federal and state levels contribute to consolidation of public finances.

Combine to compete: improving fiscal forecast accuracy over time

Budget forecasts have become increasingly important as a tool of fiscal management to influence expectations of bond markets and the public at large. The inherent difficulty in projecting macroeconomic variables – together with political bias – thwart the accuracy of budget forecasts. We improve accuracy by combining the forecasts of both private and public agencies for Italy over the period 1993-2012. A weighted combined forecast of the deficit/ ratio is superior to any single forecast. Deficits are hard to predict due to shifting economic conditions and political events. We test and compare predictive accuracy over time and although a weighted combined forecast is robust to breaks, there is no significant improvement over a simple RW model.
