Web professional de serveis informàtics, basat en software de codi obert

El PFC tracte de la implementació d'un web de serveis informàtics basat en software de codi obert i per tal de emprendre-ho i tirar endavant com a negoci, s'ha dut a terme un estudi de les tecnologies i un pla d'empresa, mirant de treu-re la màxima rendibilitat al web.Els serveis escollits com a model de negoci són bàsicament quatre: el disseny web, el disseny de webs e-commerce o tendes virtuals, la implementació de gestors de recursos d'empresa coneguts com ERP (de l'anglès Enterprise Resources Planning), i la implementació de gestors de relacions amb els clients coneguts com CRM (de l'anglès Customer Relationship Management).El primer capítol es una introducció, el segon capítol tracta de el software lliure, que és, quins models de negoci aporta i els tipus de llicència existents, el tercer capítol es un pla d'empresa on es detalla els serveis que oferirem i com ho gestionarem, el quart capítol tracta de les tecnologies utilitzades i el per que, i finalment unes conclusions.La web, netsolucion.com, que s'ha dissenyat amb Wordpress, implica no tan sols el haver d'estudiar i d'aprendre aquesta plataforma sinó també totes les que s'ofereixen com a serveis, que son:Gestor de Bases de Dades MySQL i PHP per al disseny web, Prestashop per al disseny de tendes virtuals, OpenERP per a la implementació dels gestors de recursos de empresa (ERP's) i els gestors de relacions amb els clients (CRM's).

Can we identify Walrasian allocations?

[eng] We consider a discrete time, pure exchange infinite horizon economy with two or more consumers and at least one concumption good per period. Within the framework of decentralized mechanisms, we show that for a given consumption trade at any period of time, say at time one, the consumers will need, in general, an infinite dimensional (informational) space to identigy such a trade as an intemporal Walrasian one. However, we show and characterize a set of enviroments where the Walrasian trades at each period of time can be achieved as the equilibrium trades of a sequence of decentralized competitive mechanisms, using only both current prices and quantities to coordinate decisions.

Young innovative firms and R&D strategies: is the Spanish case different?

This paper analyzes the profile of Spanish young innovative companies (YICs) and the determinants of innovation and imitation strategies. The results for an extensive sample of 2,221 Spanish firms studied during the period 2004–2010 show that YICs are found in all sectors, although they are more concentrated in high-tech sectors and, in particular, in knowledge-intensive services (KIS). Three of every four YICs are involved in KIS. Our results highlight that financial and knowledge barriers have much impact on the capacity of young, small firms to innovate and to become YICs, whereas market barriers are not obstacles to becoming a YIC. Public funding, in particular from the European Union, makes it easier for a new firm to become a YIC. In addition, YICs are more likely to innovate than mature firms, although they are more susceptible to sectoral and territorial factors. YICs make more dynamic use of innovation and imitation strategies when they operate in high-tech industries and are based in science parks located close to universities. Keywords: innovation strategies, public innovation policies, barriers to innovation, multinomial probit model. JEL Codes: D01, D22 , L60, L80, O31

A Theory of Representative Behavior in the Dictator Game

In this paper we present a model of representative behavior in the dictator game. Individuals have simultaneous and non-contradictory preferences over monetary payoffs, altruistic actions and equity concerns. We require that these behaviors must be aggregated and founded in principles of representativeness and empathy. The model results match closely the observed mean split and replicate other empirical regularities (for instance, higher stakes reduce the willingness to give). In addition, we connect representative behavior with an allocation rule built on psychological and behavioral arguments. An approach consistently neglected in this literature. Key words: Dictator Game, Behavioral Allocation Rules, Altruism, Equity Concerns, Empathy, Self-interest JEL classification: C91, D03, D63, D74.

The Transatlantic Productivity Gap : Is R&D the Main Culprit?

The literature has pointed to different causes to explain the productivity gap between Europe and United States in the last decades. This paper tests the hypothesis that the lower European productivity performance in comparison with the US can be explained not only by a lower level of corporate R&D investment, but also by a lower capacity to translate R&D investment into productivity gains. The proposed microeconometric estimates are based on a unique longitudinal database covering the period 1990-2008 and comprising 1.809 US and European companies for a total of 16.079 observations. Consistent with previous literature, we find robust evidence of a significant impact of R&D on productivity, however – using different estimation techniques - the R&D coefficients for the US firms always turn out to be significantly higher. To see to what extent these transatlantic differences may be related to the different sectoral structures in the US and the EU, we differentiated the analysis by sectors. The result is that both in manufacturing, services and high-tech sectors US firms are more efficient in translating their R&D investments into productivity increases.
