[ES]Este proyecto va dirigido al estudio de los conceptos y los patrones de la exclusión social desde una perspectiva económica. Desde el punto de vista teórico, se pretende plantear modelos que analicen las implicaciones del altruismo en relación a la lucha contra situaciones de pobreza y exclusión social, profundizando en el estudio con las herramientas que proporciona la economía experimental. Desde el punto de vista empírico, se analizan los factores que han llevado a retrocesos en la dimensión de pobreza y exclusión social de la estrategia Europa 2020. Los indicadores AROPE se basan únicamente en el recuento de excluidos y, en consecuencia, no incorporan el grado de intensidad de la exclusión que es la base de los indicadores multidimensionales de la pobreza como el IPM. Por ello, se plantea dar definiciones alternativas de medidas que permitan caracterizar la sensibilidad de los indicadores de pobreza y exclusión social, integrando en la medición la proporción de excluidos con la intensidad de la exclusión. Se pretende identificar patrones de exclusión y grupos de especial riesgo, estudiando la contribución de los posibles factores causales.

In this paper we analyse the pass-through of a commodity price shock along the food price chain in the euro area. Unlike the existing literature, which mainly focuses on food commodity prices quoted in international markets, we use a novel database that accounts for the role of the Common Agricultural Policy in the European Union. We model several departures from the linear pass-through benchmark and compare alternative specifications with aggregate and disaggregate food data. Overall, when the appropriate dataset and methodology are used, it is possible to identify a significant and longlasting food price pass-through. The results of our regressions are applied to the strong increase in food prices in the 2007-08 period; a simple decomposition exercise shows that commodity prices are the main determinant of the increase in producer and consumer prices, thus solving the pass-through puzzle highlighted in the existing literature for the euro area.

A well-established result in the theoretical literature on labour market flexibility is that the employment should be more volatile in "flexible" labour markets. Over the last 35 years, Italy gives a good example of a transition from an over-regulated labour market into a quite more flexible one. According to the theory, the deregulation is expected to increase the employment variance. Despite the anecdotal evidence reported in the press, the literature hardly finds any evidence for such an effect. This paper exploits time-series of several employment indicators since 1980, allowing us to compare decades with different labour market regulation. All the considered series show evidence of a structural break with an increase in their variance after the deregulation, confirming the expected pattern. This gives some support to the concerns for increased job insecurity.

This paper assesses empirically the effects of oil price shocks on the real economic activity of the main industrialised countries. Multivariate VAR analysis is carried out using both linear and nonlinear models. The latter category includes three approaches employed in the literature, namely, the asymmetric, scaled and net specifications. We find evidence of a non-linear impact of oil prices on real GDP. In particular, oil price increases are found to have an impact on GDP growth of a larger magnitude than that of oil price declines, with the latter being statistically insignificant in most cases. Among oil importing countries, oil price increases are found to have a negative impact on economic activity in all cases but Japan. Moreover, the effect of oil shocks on GDP growth differs between the two oil exporting countries in our sample, with the UK being negatively affected by an oil price increase and Norway benefiting from it.
