    Background: the PLATINO project was launched in 2002 in order to study the prevalence of chronic obstructive pulmonary disease (COPD) in Latin America. Because smoking is the main risk factor for COPD, detailed data on it were obtained. the aim of this paper was to evaluate the prevalence of smoking and incidence of initiation among middle-aged and older adults (40 years or older). Special emphasis was given to the association between smoking and schooling.Methods: PLATINO is a multicenter study comprising five cross-sectional population-based surveys of approximately 1,000 individuals per site in São Paulo (Brazil), Santiago (Chile), Mexico City (Mexico), Montevideo (Uruguay) and Caracas (Venezuela). the outcome variable was smoking status (never, former or current). Current smokers were those who reported to smoke within the previous 30 days. Former smokers were those who reported to quit smoking more than 30 days before the survey. Using information on year of birth and age of smoking onset and quitting, a retrospective cohort analysis was carried out. Smoking prevalence at each period was defined as the number of subjects who started to smoke during the period plus those who were already smokers at the beginning of the period, divided by the total number of subjects. Incidence of smoking initiation was calculated as the number of subjects who started to smoke during the period divided by the number of non-smokers at its beginning. the independent variables included were sex, age and schooling.Results: Non-response rates ranged from 11.1% to 26.8%. the prevalence of smoking ranged from 23.9% (95% CI 21.3; 26.6) in São Paulo to 38.5% (95% CI 35.7; 41.2) in Santiago. Males and middle-aged adults were more likely to smoke in all sites. After adjustment for age, schooling was not associated with smoking. Using retrospective cohort analysis, it was possible to detect that the highest prevalence of smoking is found between 20-29 years, while the highest incidence is found between 10-19 years. Age of smoking onset tended to decline over time among females.Conclusion: the prevalence of smoking varied considerably across sites, but was lower among countries with national anti-smoking campaigns.Univ Fed Pelotas, Pelotas, BrazilUniv Republica, Montevideo, UruguayInst Nacl Enfermedades Resp, Mexico City, DF, MexicoUniversidade Federal de São Paulo, São Paulo, BrazilPontificia Univ Catolica Chile, Santiago, ChileCent Univ Venezuela, Caracas, VenezuelaUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc

    Policy Issues in NEG Models: Established Results and Open Questions

    Get PDF
    This paper provides a non-technical overview of NEG models dealing with policy issues. Considered policy measures include alternative categories of public expenditure, international tax competition, unilateral actions of protection/liberalisation, and trade agreements. The implications of public intervention in two-region NEG models are discussed by unfolding the impact of policy measures on agglomeration/dispersion forces. Results are described in contrast with those obtained in standard non-NEG theoretical models. The high degree of abstraction limits the applicability of NEG models to real world policy issues. We discuss in some detail two extensions of NEG models to reduce this applicability gap: the cases of multi-regional frameworks and firm heterogeneity

    A test of the market potential equation in Spain

    No full text
    In this article, we examine the relationship between regional wages in Spain and the market potential of these regions in the period 1955 to 1995. We demonstrate the existence of a spatial wage structure, in which wages fall with increasing distance from the highest income regions. This result strengthens the hypothesis that agglomerative forces were operating in Spain during the second half of the twentieth century.

    New economic geography and economic history: a survey of recent contributions through the lens of the Spanish industrialization process

    Get PDF
    This paper aims to provide a synthesis of a number of articles that over the last few years have explored the industrialization process in Spain from the perspective of the new economic geography (NEG). To this end, we present some of the seminal theoretical papers of the NEG literature from which originated the main theoretical predictions that have been tested through empirical analysis applied to the case of Spain. We also look at those papers on the economic history of Spain that—through the use of an economic geography framework—have analysed how the location and regional concentration of manufacturing has evolved over the years. Altogether, this paper aims not only to present the determinants of the industrial map of Spain, but also to highlight the positive externalities that stem from the interaction between the NEG and economic history, showing the usefulness of a cliometric approach based on economic theory and empirical testing to give us a more detailed knowledge of the past

    Labour migration in the enlarged EU: a new economic geography approach

    No full text
    This paper studies the impact of migration policy liberalisation on international labour migration in the enlarged European Union (EU) in a structural economic geography approach. The liberalisation of migration policy would induce an additional 1.80-2.98% of the total EU workforce to change their country of location, with most of migrant workers relocating from the East to the West. The average net migration rate is decreasing in the level of integration, suggesting that from an economic point of view no regulatory policy responses are necessary to labour migration in the enlarged EU.labour migration, economic integration, economic geography, market access,
