Research design is quasi-experimental, field, with four longitudinal assessments for two groups (one experimental and one control) of students with irregularity student. Intervention, learns listen-think-write (lltw) method. population, 488 students. With a sample conditioned (students with irregular registration) of 170 students from two university careers of accounting and administration, both manner, 24.3 years old. Material, Raven’s Progressive Matrices test and Learning strategies ACRA test. The impact obtained by the intervention (LLTW) was 23%, significant difference between follow-up evaluation 6 and 12 months. Regarding the improvement of learning skills in post-test measurement showed a general increase in average by 28%. Also it is necessary to say, the decline was failed subjects in the two groups evolving 12 months in control group was 3 to 4 and the experimental group was 1 to 2.     

Geodemographic and socioeconomic characterization of the retail attraction of leading hypermarket chains in Spain

This paper aims at examining the impact on demand of the competitive positioning strategies developed by the leading hypermarket chains in Spain. Specifically, the purpose is to carry out a geodemographic and socieconomic characterization of the potential consumers of each chain. As retail attraction has traditionally been divided into three components, distance, mass and image, a gravitational model is proposed which distinguishes them and facilitates the evaluation of existing differences across any a priori segmentation base. The empirical test identifies significant geodemographic differences in the retail attraction of hypermarket chains. Chains seem to target the whole market by developing an image balanced against the advantages and disadvantages derived from the spatial coverage strategy. Social class is not as good an indicator of hypermarket choice as expected, although some interesting patterns have been detected.     

Global and world cities: a view from off the map

Attention to global and world cities has directed the field of urban studies to the significance of international and transnational processes in shaping city economies. This article evaluates these approaches, from a position off their maps. I argue that the circulation of these approaches in academic and policy realms adversely impacts on cities which do not fall into these categories by setting up the idea of the global city as a ‘regulating fiction’, a standard towards which they aspire. It establishes a small sector of the global economy as most desirable in planning the future of cities. By contrast, mega–cities function as the dramatic ‘other’ of world and global cities, and highlight the developmentalist discourse through which most cities in poor countries are assessed as fundamentally lacking in qualities of city–ness. I argue that the long–standing categories of western/third–world cities have been translated into the apparently transnational accounts of global and world cities. Western cities continue to be the primary site of production of apparently unlocated urban theory; so–called third–world cities (and other cities off the map of the world cities cartography) are interpreted through a developmentalist lens and, where they are referred to at all, are framed in terms of ‘difference’ or irrelevance. This article draws attention to the emergence of an alternative set of theoretical approaches, which are more inclusive in their geographical reach and which are concerned with the diverse dynamics of ordinary cities. These approaches have not yet realized that they have the potential to broaden the base for theorizing about cities and, with this in mind, the article explores the potential for a more cosmopolitan urban theory. The policy stakes in this are high, and the article notes that there are important political reasons to promote the analysis of ordinary cities in the face of the persistence of ambitions in many cities to become ‘world cities‘. L’attention accordée aux villes planétaires et mondiales a orienté le champ des études urbaines vers l’importance des processus internationaux et transnationaux dans la configuration économique des villes. Partant d’un point situé hors de leur cartographie, l’article évalue ces approches. La circulation de celles–ci dans les sphères politiques et intellectuelles a une incidence néfaste sur les villes qui n’appartiennent pas à ces catégories, car elle instaure l’idée d’une ville planétaire en tant que ‘fiction régulatrice’, norme à laquelle aspirent les villes. Un secteur restreint de l’économie mondiale est ainsi établi comme le plus recherché dans la planification urbaine. Par contraste, les megacities fonctionnent comme l’impressionnant ‘autre’ des villes mondiales et planétaires, valorisant le discours développementaliste selon lequel l’évaluation des villes des pays pauvres indique le plus souvent des lacunes fondamentales dans les qualités propres à une ville. Les anciennes catégories de villes (Occident/tiers–monde) ont été converties en justifications apparemment transnationales des villes planétaires et mondiales. Les villes occidentales restent le site de production principal d’une théorie urbaine manifestement non–localisée; les villes dites du tiers monde (et autres villes ignorées de la cartographie des villes mondiales) sont interprétées à travers une optique développementaliste et, si on en parle, sont dépeintes en termes de ‘différence‘ ou d’inadéquation. Cet article souligne l’émergence d’un autre ensemble d’approches théoriques, plus inclusives dans leur géographie et soucieuses des diverses dynamiques des villes ordinaires. Sachant que ces démarches ne sont pas encore conscientes de pouvoir étendre la base théorique sur les villes, l’article explore la possibilité d’une théorie urbaine plus cosmopolite. Les enjeux stratégiques sont sérieux et il existe des raisons politiques importantes d’encourager l’analyse des villes ordinaires face aux ambitions persistantes dans de nombreuses villes de devenir les ‘villes mondiales’.     

Markets,torts, and social inefficiency

We provide a model wherein oligopolists produce differentiated products that also have a safety attribute. Consumption of these products may lead to harm (to consumers and/or third parties), lawsuits, and compensation, either via settlement or trial. Firm‐level costs reflect both safety investment and production activities, as well as liability‐related costs. Compensation is incomplete, both because of inefficiencies in the bargaining process and (possibly) because of statutorily established limits on awards. We compare the market equilibrium safety effort and output levels to what a planner who is able to set safety standards, but takes the market equilibrium output as given, would choose.     

Block Share Purchases and Corporate Performance

This paper investigates the causes and consequences of activist block share purchases in the 1980s. We find that activist investors were most likely to purchase large blocks of shares in highly diversified firms with poor profitability. Activists were not less likely to purchase blocks in firms with shark repellents and employee stock ownership plans. Activist block purchases were followed by increases in asset divestitures, decreases in mergers and acquisitions, and abnormal share price appreciation. Industry-adjusted operating profitability also rose. This evidence supports the view that the market for partial corporate control plays an important role in limiting agency costs in U.S. corporations.     

Targeting fertility and female participation through the income tax

We evaluate the effect of a 2003 reform in the Spanish income tax on fertility and the employment of mothers with small children. The reform introduced a tax credit for working mothers with children under the age of three, while also increasing child deductions for all households with children. Theoretically, given the interplay of these two components, the expected effect of the reform is ambiguous on both outcomes. We find that the combined reforms significantly increased both fertility (by almost 5%) and the employment rate of mothers with children under three (by 2%). These effects were more pronounced among less-educated women. In addition, to disentangle the impact of the two reform components, we use an earlier reform that increased child deductions in 1999. We find that the child deductions affect mothers' employment negatively, which implies that the 2003 tax credit would have increased employment even more (up to 5%) in the absence of the change in child deductions.     

The ECB's New Multi-Country Model for the euro area: NMCM — Simulated with rational expectations

The model presented here is an estimated medium-scale New Multi-Country Model (NMCM) which covers the five largest euro area countries and is used for forecasting and scenario analysis at the European Central Bank. The model has a tight theoretical structure which allows for non-unitary elasticity of substitution, non-constant augmenting technical progress and heterogeneous sectors with differentiated price and income elasticities of demand across sectors. Furthermore, it has the explicit inclusion of expectations on the basis of three optimising private sector decision making units: i.e. firms, trade unions and households, where output is in the short run demand-determined and monopolistically competing firms set prices and factor demands. Labour is indivisible and monopoly-unions set wages and households make consumption/saving decisions.We assume that agents optimise under limited information where each agent knows only the parameters related to his/her optimisation problem. Therefore we estimate with GMM, which implicitly assumes limited information boundedly rational expectations. In this paper we provide some simulation results under the assumption of model-consistent rational expectations, we show that there is some heterogeneity across countries and that the reactions of the economies to shocks depend strongly on whether the shocks are pre-announced, announced and credible or unannounced and uncredible.
