La recerca es centra en l'™obra de divulgació cientí­fica d'™Antoni Bergnes de las Casas al llarg del segle XIX a Barcelona. En les obres i revistes que publicà destaca la difusió de noves concepcions en la història natural. En elles es divulga la teoria evolucionista de Lamarck i d'altres models evolutius similars, però que defensen la intervenció divina en el procés. Aquests fets posen de manifest la presència de teories evolutives a Catalunya i a Espanya en la primera meitat del segle XIX, i de la teoria evolucionista de Lamarck a principi dels anys seixanta del segle.

Aquest text fa referència a una pintura a l’oli dedicada a sant Josep Oriol, conservada a l’església parroquial de la Pobla de Segur. Arran d’una anàlisi iconogràfica atenta de l’obra, dedicada a un sant beatificat a Barcelona el juny del 1807, un fet que comportà nombroses representacions de la mà dels artistes més notables, apunta la possibilitat, que pogués ser obra de Bonaventura Planella (1772-1844).

This paper assesses empirically the importance of size discrimination and disaggregate data for deciding where to locate a start-up concern. We compare three econometric specifications using Catalan data: a multinomial logit with 4 and 41 alternatives (provinces and comarques, respectively) in which firm size is the main covariate; a conditional logit with 4 and 41 alternatives including attributes of the sites as well as size-site interactions; and a Poisson model on the comarques and the full spatial choice set (942 municipalities) with site-specific variables. Our results suggest that if these two issues are ignored, conclusions may be misleading. We provide evidence that large and small firms behave differently and conclude that Catalan firms tend to choose between comarques rather than between municipalities. Moreover, labour-intensive firms seem more likely to be located in the city of Barcelona. Keywords: Catalonia, industrial location, multinomial response model. JEL: C250, E30, R00, R12

We study collusive behaviour in experimental duopolies that compete in prices under dynamic demand conditions. In one treatment the demand grows at a constant rate. In the other treatment the demand declines at another constant rate. The rates are chosen so that the evolution of the demand in one case is just the reverse in time than the one for the other case. We use a box-design demand function so that there are no issues of finding and co-ordinating on the collusive price. Contrary to game-theoretic reasoning, our results show that collusion is significantly larger when the demand shrinks than when it grows. We conjecture that the prospect of rapidly declining profit opportunities exerts a disciplining effect on firms that facilitates collusion and discourages deviation.

L’objectiu d’aquest treball és estudiar la popularització de la frenologia i del mesmerisme (també conegut com a magnetisme animal) a la Catalunya de mitjan segle XIX. A Catalunya el procés de popularització d’aquestes ciències va tenir el seu punt àlgid durant la primera meitat de la dècada de 1840, coincidint amb les activitats del frenòleg Marià Cubí Soler (1801-1875). El treball demostra la importància del context polític i cultural, així com la incomoditat que generaven les pràctiques de frenòlegs i magnetitzadors com a elements clau per entendre les actituds de l’elit intel•lectual catalana vers la introducció d’aquestes noves ciències.

Calculating explicit closed form solutions of Cournot models where firms have private information about their costs is, in general, very cumbersome. Most authors consider therefore linear demands and constant marginal costs. However, within this framework, the nonnegativity constraint on prices (and quantities) has been ignored or not properly dealt with and the correct calculation of all Bayesian Nash equilibria is more complicated than expected. Moreover, multiple symmetric and interior Bayesianf equilibria may exist for an open set of parameters. The reason for this is that linear demand is not really linear, since there is a kink at zero price: the general ''linear'' inverse demand function is P (Q) = max{a - bQ, 0} rather than P (Q) = a - bQ.
