Stochastic monotonicity in intergenerational mobility tables

The aim of this paper is to test for stochastic monotonicity in intergenerational socio‐economic mobility tables. In other words, we question whether having a parent from a high socio‐economic status is never worse than having one with a lower status. Using existing inferential procedures for testing unconditional stochastic monotonicity, we first test a set of 149 intergenerational mobility tables in 35 different countries and find that monotonicity cannot be rejected in hardly any table. In addition, we propose new testing procedures for testing conditional stochastic monotonicity and investigate whether monotonicity still holds after conditioning on a number of covariates such as education, cognitive and non‐cognitive skills. Based on the NCDS cohort data from the UK, our results provide evidence that monotonicity holds, even conditionally. Moreover, we do not find large differences in our results when comparing social class and wage class mobility. Copyright © 2010 John Wiley & Sons, Ltd.     

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.     

Road accessibility and cohesion in lagging regions: Empirical evidence from Portugal based on spatial econometric models

A number of transportation infrastructure projects were conducted in Europe during the 1990s with the explicit objective of promoting regional cohesion goals through the improvement of the accessibility of peripheral regions. Given its peripheral situation in the Union, Portugal was a key target for some of these projects. A decade later, it is pertinent to ask whether the new infrastructure achieved its objective of promoting lagging regions. The objective of this paper is to analyze one of the lagging regions in Portugal, to try to establish the link between changes in accessibility levels brought by improvements in the transportation network, and two indicators commonly used in accessibility research (population and purchasing power), while controlling other variables of possible relevance, such as the levels of educational achievement of the population in the region. The analysis is based on the use of spatially autoregressive models which allow the representation of accessibility as spatially lagged variables of first and second order. The results place the contribution of accessibility changes in context, and point at the relevance of education as an alternative policy.     

Liberalisation and Protection under Overlapping Free Trade Agreements: Dynamic Interplay between Free Trade Agreements and Investment

Two decades into the most recent wave of regionalism many of its implications remain to be fully understood. A vast literature has explored the impacts of free trade agreements (FTAs) on investment flows, but less attention has been given to how existing patterns of investment alter FTA liberalisation. It is contended here that the dynamic interplay between overlapping FTA areas and the investment sunk in them shapes governments' and firms' positions regarding further FTA liberalisation. During trade negotiations, a country may decide to exclude a sector from FTA liberalisation to prevent (concession prevention) future FTA partners from making similar demands. Concession prevention could also occur when a foreign firm, holding a dominant market position in a host country, relinquishes liberalisation demands in an FTA between host and home countries to prevent its current position being eroded if the host country grants similar (or better) concessions to competing firms from other countries in future FTAs. Conversely, investment sunk into a country's sensitive sector in the territory of partners from previous FTAs could pre‐empt (concession pre‐emption) the protectionist position of that country when it subsequently negotiates FTAs with the investment‐source countries. These arguments were tested in the negotiations around the liberalisation of the automotive industry that Thailand and Malaysia had with Japan in their respective bilateral FTAs. The distinct interaction between investment and the FTAs in which these countries participate resulted either in entrenchment of protectionism in the sector or its liberalisation across subsequent FTAs.
