The suburban question: grassroots politics and place making in Spanish suburbs
Manuel Castells spoke of the urban as a unit of collective consumption, yet much of the politics of collective consumption he documented was evident in the suburbs. The tendency for suburbs of most complexions to lack services and amenities has been and continues to be a focus of politics in Europe. In Spain, as elsewhere in Europe, a grassroots politics surrounding the making good of these deficits in basic services and amenities has broadened and formalised somewhat to become part of a competitive local representative politics concerned with shaping a sense of place. Here we consider this legacy of grassroots politics as it has played out more recently in a politics of place making in Getafe and Badalona in metropolitan Madrid and Barcelona, respectively. In conclusion, we suggest that this enduring suburban question—of making the suburban urban—places them at the centre of contemporary metropolitan governance and politics. However, it also raises further issues for study—notably, the scalar politics in which suburban place making is empowered or constrained, the role of political parties and individual politicians on the place-making process, and the point at which grassroots politics of collective consumption becomes urban entrepreneurialism

Acceso al mercado de productos lácteos de Europa: Un análisis de equilibrio parcial para evaluar las potenciales ganancias de los exportadores argentinos
A partial equilibrium model is used to quantify price differentials not explained by tax policy and efficiency cost in the international trade of dairy products between Argentina and some countries of European Union (EU). Prices of imports of EU from Argentina and European producer of the domestic variety welfare fall when liberalization of non-tariff barriers are reduced or eliminated as well as European consumer’s welfare and Argentinean exporter’s earnings are increased.
A sensibility analysis is carried out, changing substitution and supply elasticity and exporter’s earnings are shown for four alternative stages. The conclusions are that exporters obtain higher earnings by eliminating or reducing non-tariff barriers when substitution elasticity is higher, mainly for cheese. More inelastic supply products obtain higher earnings for Argentinean exporters (mainly in powdered milk). Finally, an alternative stage is explored where elimination of non-tariff barriers results in higher imports from the rest of the world. Results show a greater increase in Argentinean exporter’s earnings for cheese products and lower earnings for powdered milk
Decoupling and Recoupling
We develop a stylized model that captures the phenomena of decoupling and recoupling in an environment where heterogeneous entrepreneurial sectors face financial constraints in their relationship with a common set of lenders. In response to adverse shocks, a financially constrained sector must reduce its borrowing and cut down on production. In particular, as the constrained sector absorbs less and less capital, the real interest rate in the economy declines. Other sectors that compete for the same inputs (including capital) thus experience lower costs, which boosts investment, output, and profits, reflecting the phenomenon of "decoupling." As long as the shock is small, the entrepreneurial sector repays what is owed and the lenders' ability to supply funds is unaffected. For large shocks, however, the constrained sector is no longer able to honor its debts in full and lenders experience losses that erode their lending base. This induces them to cut their supply of credit to the rest of the economy, which reduces output and profit for all other entrepreneurial sectors, capturing the phenomenon of "recoupling" or contagion.
Cocliques of maximal size in the prime graph of a finite simple group
In this paper we continue our investgation of the prime graph of a finite
simple group started in http://arxiv.org/abs/math/0506294 (the printed version
appeared in [1]). We describe all cocliques of maximal size for all finite
simple groups and also we correct mistakes and misprints from our previous
paper. The list of correction is given in Appendix of the present paper.Comment: published version with correction
Access to European dairy product markets: A Computable Partial Equilibrium analysis to assess Argentine exporters surplus

Assessing the efects of eliminating non-tariff barriers over the Argentine Textile Exports
This paper offers a quantification of price differentials not explained by tariff policy and the assessment of efficiency costs burned on different economic agents involved in textile products trade between Argentina (exporter) and Brazil (domestic producer). Simulations are carried out to show the effects of the distortion of price differentials, considered like non tariff barriers or a set of them and others obstacle to trade. From the removal of non tariff barriers results that consumers and exporters obtain grater consumer surplus and profits, respectively, while domestic producers loose part of their producer surplus. Consumers and exporters are better because of changes in terms of trade; in some products consumers obtain graters benefits than exporters and vice versa. Likewise, changes in elasticities (direct elasticity of supply and demand) were simulated to observe distortions in previous results.Textile sector; computable partial equilibrium; commercial policy
