    Effect of climate and geography on worldwide fine resolution economic activity

    Get PDF
    Geography, including climatic factors, have long been considered potentially important elements in shaping socio-economic activities, alongside other determinants, such as institutions. Here we demonstrate that geography and climate variables satisfactorily explain the worldwide economic activity as measured by the per capita Gross Cell Product (GCP-PC) at a fine geographical resolution, typically much higher than country average. A 1° by 1° GCPPC dataset has been key for establishing and testing a direct relationship between 'local' geography/climate and GCP-PC. Not only have we tested the geography and climate hypothesis using many possible explanatory variables, importantly we have also predicted and reconstructed GCP-PC worldwide by retaining the most significant predictors. While this study confirms that latitude is the most important predictor for GCP-PC when taken in isolation, the accuracy of the GCP-PC prediction is greatly improved when other factors mainly related to variations in climatic variables, rather than average climatic conditions as typically used, are considered. However, latitude diminishes in importance when only the wealthier parts of the globe are considered. This work points to specific features of the climate system which explain economic activity, such as the variability in air pressure. Implications of these findings range from an improved understanding of why socio-economically better-off societies are geographically placed where they are in the present, past and future to informing where new economic activities could be established in order to yield favourable economic outcomes based on geography and climate conditions

    The Community Structure of the Global Corporate Network

    Get PDF
    We investigate the community structure of the global ownership network of transnational corporations. We find a pronounced organization in communities that cannot be explained by randomness. Despite the global character of this network, communities reflect first of all the geographical location of firms, while the industrial sector plays only a marginal role. We also analyze the network in which the nodes are the communities and the links are obtained by aggregating the links among firms belonging to pairs of communities. We analyze the network centrality of the top 50 communities and we provide the first quantitative assessment of the financial sector role in connecting the global economy

    The cultural, ethnic and linguistic classification of populations and neighbourhoods using personal names

    There are growing needs to understand the nature and detailed composition of ethnicgroups in today?s increasingly multicultural societies. Ethnicity classifications areoften hotly contested, but still greater problems arise from the quality and availabilityof classifications, with knock on consequences for our ability meaningfully tosubdivide populations. Name analysis and classification has been proposed as oneefficient method of achieving such subdivisions in the absence of ethnicity data, andmay be especially pertinent to public health and demographic applications. However,previous approaches to name analysis have been designed to identify one or a smallnumber of ethnic minorities, and not complete populations.This working paper presents a new methodology to classify the UK population andneighbourhoods into groups of common origin using surnames and forenames. Itproposes a new ontology of ethnicity that combines some of its multidimensionalfacets; language, religion, geographical region, and culture. It uses data collected atvery fine temporal and spatial scales, and made available, subject to safeguards, at thelevel of the individual. Such individuals are classified into 185 independentlyassigned categories of Cultural Ethnic and Linguistic (CEL) groups, based on theprobable origins of names. We include a justification for the need of classifyingethnicity, a proposed CEL taxonomy, a description of how the CEL classification wasbuilt and applied, a preliminary external validation, and some examples of current andpotential applications

    Space, growth and technology: an integrated dynamic approach

    Get PDF
    Economic phenomena are interrelated. From a growth perspective, time analysis concerning the choices of present and future consumption and the choices between the allocation of scientific resources should be combined with a space analysis regarding the dissemination of economic activity through geographical locations. This paper intends to present such an integrated approach under a simple endogenous growth model. The determinants of growth are, on one hand, the decisions about how to allocate technological resources and, on the other hand, the strength with which productive activities can agglomerate in order to generate increasing returns to scale. We find that the long run steady state does not have to be a state of unchangeable geography – consumption and production conditions and technological progress not only determine long term growth but also the long term tendency for the economy to geographically concentrate or disperse.Optimal control; Economic growth; Technology; Agglomeration economies; Increasing returns

    The UK's global gas challenge

    Get PDF
    A UKERC Research Report exploring the UK's global gas challenge. This report takes an interdisciplinary perspective, which marries energy security insights from politics and international relations, with detailed empirical understanding from energy studies and perspectives from economic geography that emphasise the spatial distribution of actors, networks and resource flows that comprise the global gas industry. Natural gas production in the UK peaked in 2000, and in 2004 it became a net importer. A decade later and the UK now imports about half of the natural gas that it consumes. The central thesis of the project on which this report is based is that as the UK’s gas import dependence has grown, it has effectively been ‘globalising’ its gas security; consequently UK consumers are increasingly exposed to events in global gas markets. - See more at: http://www.ukerc.ac.uk/publications/the-uk-s-global-gas-challenge.html#sthash.wEP831Zn.dpu

    Using image-based modelling (SfM-MVS) to produce a 1935 ortho-mosaic of the Ethiopian highlands

    Get PDF
    Approximately 34,000 aerial photographs covering large parts of Ethiopia and dating back to 1935-1941 have been recently recovered. These allow investigating environmental dynamics for a past period that until now is only accessible from terrestrial photographs or narratives. As the archive consists of both oblique and vertical aerial photographs that cover rather small areas, methods of image-based modelling were used to orthorectify the images. In this study, 9 vertical and 18 low oblique aerial photographs were processed as an ortho-mosaic, covering an area of 25 km(2), west of Wukro town in northern Ethiopia. Using 15 control points (derived from Google Earth), a Root Means Square Error of 28.5 m in X 35.4 m in Y were achieved. These values can be viewed as optimal, given the relatively low resolution and poor quality of the imagery, the lack of metadata, the geometric quality of the Google Earth imagery and the recording characteristics. Land use remained largely similar since 1936, with large parts of the land being used as cropland or extensive grazing areas. Most remarkable changes are the strong expansion of the settlements as well as land management improvements. In a larger effort, ortho-mosaics covering large parts of Ethiopia in 1935-1941 will be produced

    The Geography of Employment Polarisation in Britain

    Get PDF
    This paper investigates the regional and subregional patterns of employment polarisation in Great Britain. Extending recent econometric evidence for employment polarisation at the national level, the focus of analysis is to examine the geography of this polarisation. Methodological issues on how we define and measure ‘job polarisation’ are presented and plausible theories for explaining this polarisation are reviewed. It has been suggested that low-quality jobs, defined either as low-paid jobs or low-skill jobs, depend increasingly on the growth of employment and wages of high-quality jobs. The presence of a growing high-income workforce in the economy generates consumer demand for local services leading this way to an increase in the low-skill employment sector. As these local services refer mainly to the non-traded sector of the economy, this hypothesis implies physical proximity of the low-skilled and high-skilled jobs. Therefore, in the empirical part of the paper, econometric techniques are used in order to investigate the location of job polarisation. Specifically, we examine whether employment polarisation happens within regions or just across regions and test further for such evidence at the subregional level and neighbouring localities. New Earnings Survey (NES) microdata that span over a long time period and are workplace-based are used for such purposes. Furthermore, evidence for dependency of low-skill jobs on high-skill ones at the local level and possible urban-specificity of the phenomenon are investigated. Taking into account the importance of employment shifts, changes in median wages of the different jobs and within job-inequality for explaining the increase in earnings inequality in GB in the recent decades, the contribution of employment polarisation to the actual rise in inequality is examined. Additionally, the paper examines whether employment polarisation patterns are associated with regional differences in the labour force composition.
