The economic theory and the Portuguese manufactured industry. Another approach

The aim of this paper is to present a further contribution to the analysis of absolute convergence, associated with the neoclassical theory, of the manufactured industry productivity at regional level and for the period from 1995 to 1999 (1)(Martinho, 2011a). This work aims, also, to test the Verdoorn Law, with the alternative specifications of (2)Kaldor (1966), for the five Portuguese regions (NUTS II), from 1995 to 1999. It is intended to test, yet in this work, the alternative interpretation of (3)Rowthorn (1975) about the Verdoorn's Law for the same regions and period (4)(Martinho, 2011b). This paper pretends, yet, to analyze the importance which the natural advantages and local resources are in the manufacturing industry location, in relation with the "spillovers" effects and industrial policies. To this, we estimate the Rybczynski equation matrix for the various manufacturing industries in Portugal, at regional level (NUTS II) and for the period 1995 to 1999 (5)(Martinho, 2011c)

A model based on the Rybczynski equation for Portugal. Another way

We built a model analyzing the importance which the natural advantages and local resources are in the manufacturing industry location, in relation with the "spillovers" effects and industrial policies. To this, we estimate the Rybczynski equation matrix for the various manufacturing industries in Portugal, at regional level (NUTS II) and for the period 1995 to 1999. As a summary conclusion, noted that the location of manufacturing in Portugal is still mostly explained by specific factors, with a tendency to increase in some cases the explanation by these factors, having the effect "spillovers" and industrial policies little importance in this context.geographical concentration; Portuguese regions; linear models

Spatial autocorrelation and Verdoorn law in the Portuguese nuts III

This study analyses, through cross-section estimation methods, the influence of spatial effects in productivity (product per worker), at economic sectors level of the NUTs III of mainland Portugal, from 1995 to 1999 and from 2000 to 2005 (taking in count the data availability and the Portuguese and European context), considering the Verdoorn relationship. From the analyses of the data, by using Moran I statistics, it is stated that productivity is subject to a positive spatial autocorrelation (productivity of each of the regions develops in a similar manner to each of the neighbouring regions), above all in services. The total sectors of all regional economy present, also, indicators of being subject to positive autocorrelation in productivity. Bearing in mind the results of estimations, it can been that the effects of spatial spillovers, spatial lags (measuring spatial autocorrelation through the spatially lagged dependent variable) and spatial error (measuring spatial autocorrelation through the spatially lagged error terms), influence the Verdoorn relationship when it is applied to the economic sectors of Portuguese regions. The results obtained for the two periods are different, as expected, and are better in second period, because, essentially, the European and national public supports.Spatial Econometrics, Economic Growth, Productivity Analysis, Regional Development

Polarization versus agglomeration

The aim of this paper is to analyze the processes of polarization and agglomeration, to explain the mechanisms and causes of these phenomena in order to identify similarities and differences. As the main implication of this study should be noted that both process pretend to explain the concentration of economic activity and population in certain places, through cumulative phenomena, but with different perspectives, in other words, the polarization with a view of economic development and agglomeration with a perspective of space.polarization; agglomeration; economic activity

Application of Keynesian and convergence theories in Portugal. Differences and similarities

This work aims to test the Verdoorn Law, with the alternative specifications of (1)Kaldor (1966), for the 28 NUTS III Portuguese in the period 1995 to 1999. It is intended to test, also in this work, the alternative interpretation of (2)Rowthorn (1975) about the Verdoorn's Law for the same regions and periods. With this study we want, yet, to test the Verdoorn´s Law at a regional and a sectoral levels (NUTs II) for the period 1995-1999. The importance of some additional variables in the original specification of Verdoorn´s Law is also tested, such as, trade flows, capital accumulation and labour concentration. This study analyses, yet, through cross-section estimation methods, the influence of spatial effects in productivity in the NUTs III economic sectors of mainland Portugal from 1995 to 1999, considering the Verdoorn relationship. The aim of this paper is, also, to present a further contribution, with panel data, to the analysis of absolute convergence, associated with the neoclassical theory, and conditional, associated with endogenous growth theory, of the sectoral productivity at regional level (from 1995 to 1999). The structural variables used in the analysis of conditional convergence is the ratio of capital/output, the flow of goods/output and location ratio.Verdoorn law; convergence; spatial autocorrelation; Portuguese regions

Regional agglomeration in Portugal: a linear analysis

This work aims to study the Portuguese regional agglomeration process, using the linear form the New Economic Geography models that emphasize the importance of spatial factors (distance, costs of transport and communication) in explaining of the concentration of economic activity in certain locations. In a theoretical context, it is intended to explain the complementarily of clustering models, associated with the New Economic Geography, and polarization associated with the Keynesian tradition, describing the mechanisms by which these processes are based. As a summary conclusion, we can say which the agglomeration process shows some signs of concentration in Lisboa e Vale do Tejo (which is evidence of regional divergence in Portugal) and the productivity factor significantly improves the results that explain the regional clustering in Portugal (despite being ignored in the models of New Economic Geography).agglomeration; Portuguese regions; linear models

The Economic Theory and the Portuguese Manufactured Industry

This work aims to compare the Keynesian theory, namely by the Verdoorn Law, the neoclassical theory, by the absolute convergence, and the geographic concentration, by the Rybczynski equation, explanations about the different manufactured industry of the Portuguese regions (NUTs II), for the period 1986-1994. The Verdoorn Law, is tested with the alternative specifications of Kaldor (1966. The absolute convergence is tested for the productivity. To analyze the geographic concentration, with Rybczynski equation, is tested the importance which the natural advantages and local resources are in the manufacturing industry location, in relation with the "spillovers" effects and industrial policies. --Verdoorn law,convergence theories,geographic concentration,panel data,manufactured industries,Portuguese regions

The importance of increasing returns to scale in the process of agglomeration in Portugal: A non linear empirical analysis

With this work we try to analyse the agglomeration process in the Portuguese regions, using the New Economic Geography models. In these models the base idea is that where has increasing returns to scale in the manufactured industry and low transport costs, there is agglomeration. Of referring, as summary conclusion, that with this work the existence of increasing returns to scale and low transport cost, in the Portuguese regions, was proven and as such the existence of agglomeration in Portugal.new economic geography; non linear models; Portuguese regions
