Is foreign trade important for regional growth? Empirical evidence from Portugal

The aim of this study is to investigate whether openness, export shares or trade balances affect regional growth in Portugal. Human capital is also considered as a conditional factor to growth, expressed by the rate of success in high school education. Thus, we analyse whether the combination of international trade and human capital is relevant to explain regional growth in Portugal and how it affects the convergence process between regions. In the empirical analysis, interaction terms are introduced to explore the existence of different performances between regions of the Littoral and the Interior. As an alternative to the traditional approach that considers the population growth rate, we include the share of sectoral employment aiming to capture labour specialisation in the main sectors of economic activity and measure its impact on regional growth.The empirical analysis estimates the conditional convergence model of the Barro's type, applied to the Portuguese NUTS3 regions for the period 1996-2005. The GMM estimation approach applied to regional panel data reveals that factors associated with external trade, human capital and sectoral labour share (especially of the industrial sector) are relevant to explain regional growth and convergence in Portugal.     

The Financial Resource Curse*

In this paper, we present a model of the financial resource curse (i.e., episodes of abundant access to foreign capital coupled with weak productivity growth). We study a two‐sector (i.e., tradable and non‐tradable) small open economy. The tradable sector is the engine of growth, and productivity growth is increasing with the amount of labor employed by firms in the tradable sector. A period of large capital inflows, triggered by a fall in the interest rate, is associated with a consumption boom. While the increase in tradable consumption is financed through foreign borrowing, the increase in non‐tradable consumption requires a shift of productive resources toward the non‐tradable sector at the expenses of the tradable sector. The result is stagnant productivity growth. We show that capital controls can be welfare‐enhancing and can be used as a second‐best policy tool to mitigate the misallocation of resources during an episode of financial resource curse.     

Growth,unemployment and labour market institutions: evidence from a cross-section of EU regions

The responsiveness of unemployment to growth is an issue of ongoing political and academic interest. Economic growth is supposed to be the key to increase labour demand and reduce unemployment. Departing from Okun's law, most research on the unemployment intensity of growth has focused on national disparities and the role of labour market institutions. Empirical evidence at the regional level is scarce. We investigate differences in regional labour market responsiveness and their potential determinants for a cross section of European regions. The data set covers the NUTS 2 regions in the EU15 for the period 1980 to 2002. Following a spatial modelling approach interaction among neighbouring labour markets is taken into account. Our findings point to substantial differences in labour market effects of output growth among European countries and regions. Both national labour market institutions and regional characteristics, such as structural change explain a significant part of these disparities.     

Are wages equal across sectors of production?

The assumption that national labour markets are homogeneous across tradable and non‐tradable goods is common in multisector (open‐economy) macro models and crucial for the prominent Balassa–Samuelson hypothesis. To test it, this study introduces a novel, theory‐based method of distinguishing the tradable and non‐tradable sectors to the Balassa–Samuelson literature and employs modern empirical methods and a large and detailed macro dataset. It finds that both the internal relationship between productivity and wages in the tradable and non‐tradable sectors postulated by the Balassa–Samuelson hypothesis and its external transmission mechanism are rejected.     

Regional economic growth disparities: A political economy perspective

Regional differences in economic growth have been observed within many countries. Our story emphasises three region-specific factors driving growth—capital, labour and political factors. Conditional on differences in production factor (i.e., labour and capital) variations across democratic states, what role do differences in underlying “political factors” across regions play in accounting for regional growth disparities? We build a political economy model of endogenous growth where regions have the same political institutions, but experience different (and estimable) distributions over voter political biases (i.e., our “political factors”). In our model, political factors affect regional productivity as a consequence of politico-economic equilibrium. We discipline our regional growth accounting exercises by calibrating/estimating each model to American state-level economic and political-survey data. We show that the capital factor is the predominant driving force behind growth in American states. Nevertheless, regional variations in distributions of voter's political biases also account a great deal for regional growth disparities. We also evaluate how much politics would have distorted agents' welfare and regional growth, were regional economies given the opportunity to live under an efficient social planner's allocation system; and, if agents were to live under the same democratic system but where all voters have equal voting influence.     

Efficiency change,technological change and capital accumulation in Italian regions: a sectoral study

This paper examines the sources of labour productivity in the Italian regions during the period 1980–2004. Five economic sectors are investigated using data envelopment analysis (DEA) and taking into account productive specialisation and sector inefficiencies. Labour productivity change is decomposed into five components by means of Malmquist productivity indices: intra-sector efficiency change, composition efficiency change, input-biased technical change, magnitude component technical change and capital accumulation. Using bootstrap procedure, the components of labour productivity changes are statistically tested. Efficiency analysis shows that productive specialisation is not a source of inefficiency and efficiency gains can be obtained by sector-specific policies. Thus, it is possible to obtain improvements in efficiency in each sector of activity rather than reallocating resources among sectors. The results of the decomposition by sectors reveal heterogeneous sources of growth. The total economy has shown evidence of non-neutral technical change and, it has been found that agriculture, industry and construction experienced capital using technical change. The analysis of the decomposition of the labour productivity growth is complemented by an analysis of β-convergence.     

General Equilibrium Tragedy of the Commons

Many poor economies depend on open access resources for their livelihoods. Households in resource-based economies allocate their time and other factors between resource extraction and other activities. As a result, factors may shift from one sector to another as marginal returns change. This has two important implications. First, it implies potentially strong linkages between resource and non-resource sectors. Second, it means that unmanaged resources cause inefficient allocations of inputs across all sectors, and the effects of resource management spill into other sectors. We construct a local general equilibrium model that accounts for inputs that over-allocate to an open access resource and create a general equilibrium tragedy of the commons. This model describes resource rent dissipation more adequately in economies with mobile factors than a model with slowly dissipating rents. Perfectly mobile factors dissipate rent in every period, but endogenous wages cause labor and capital allocations to change with the resource stock. We use the model to illustrate medium-run impacts of a limit on capital in an artisanal fishery in Honduras. Simulation results reveal that fishery management has economy-wide impacts on prices and wages. Managers in developing countries thus should consider these linkages when implementing policies to conserve fish stocks.     

Human capital effects on labour productivity in EU regions

Recent years have seen a wealth of articles on spatial effects in empirical growth specifications. Endogenous growth models, together with the arguments of the new economic geography, have led to spatial dependence being identified with the existence of externalities which cross regional borders. This article continues in this line of research and offers new empirical evidence on the contribution of human capital and agglomeration economies to the differences in productivity in European Union regions. The article uses the spatial Durbin model with different weight matrices to explain the relation between human capital variables and labour productivity, with the advantage that it allows the effects of spatial externalities associated to human capital and agglomeration economies to be quantified.     

Must improved labor standards hurt accumulation in the targeted sector? Stylized analysis of a developing economy

This paper analyzes a stylized small open economy that consists of two tradable output-producing sectors: a manufacturing sector and a (mainly tourism-related) services sector. Assuming sectoral differences based on stylized facts, we explore the impact of higher labor standards in the manufacturing sector on the long-term prospects of the economy using comparative dynamic exercises to analyze changes in relative prices, foreign capital flows, and the sectoral distribution of investment and output. We find, in particular, that imposing higher standards across the manufacturing sector could, under certain conditions, shift the structure of the domestic economy in favor of that sector. This result is driven by changes in relative profitability in the presence of learning-by-exporting.     

Productivity Growth of the Nontradable Sectors in China

Little is known about the total factor productivity of the nontradable sectors in China. In this paper we estimate productivity growth of the nontradable sectors by studying the relative price movements of the nontradable sectors vis‐à‐vis the tradable sectors, i.e. changes in the internal real exchange rate. We find that prices of the nontradable sectors have risen significantly faster than those of the tradable sectors since China's accession to the WTO, and as a result China's internal real exchange rate has appreciated faster than the renminbi real effective exchange rate. We also find that the nontradable sectors have seen much lower productivity growth than the tradable sectors. We argue that it is important to raise China's productivity growth in the nontradable sectors through policy actions to achieve growth rebalancing and containing inflationary pressures in the medium run.     

Soaring dragons,roaring tigers,growling bears

We perform a comparative analysis of regional growth and convergence in China, Russia and India over the period 1993–2003 by means of non‐parametric methods and kernel density estimates. Our results indicate that wealthy regions were largely responsible for the rapid growth in all three countries. For China and India, capital dissipation was identified as the major determinant of regional growth. In Russia, capital deepening impeded positive changes in labour productivity, leaving technological change as the only source of regional growth. Furthermore, we find that the increasing regional income inequality in all three countries was driven by technological change which more than offset the convergence resulting from capital deepening in China and India.     

Determinants of foreign direct investment in Spain

This study utilizes panel data as a means of examining the determinants of foreign direct investment (FDI) in Spain. Data that are taken in the period 1993–2002 are used in order to estimate the determinants of FDI, at the sectoral level, by differentiating the manufacturing sectors, and at the regional level. The analysis investigates the sectoral, regional and macroeconomic variables that have successfully attracted FDI inflows from those that have not. Empirical results suggest that the differential between labour productivity and the cost of labour has been an important determinant of FDI in Spain during the period 1993–2002. Factors related to demand, the evolution of human capital, the export potential of the sectors and certain macroeconomic determinants that measure the differential between Spain and the European Union average, also play a very important role in attracting flows of FDI. Certain policy issues that are relevant to the results are also discussed.     

Land-use changes, forest/soil conditions and carbon sequestration dynamics: A bio-economic model at watershed level in Nepal

A dynamic bio-economic model has been used at watershed level in Nepal to analyze the land-use changes, forest and soil conditions and their resultant impacts on carbon (C) sequestration. Planning horizon of the model extends over a period of 25 years. The objective function is maximization of the sum of discounted net income flows from agriculture, livestock and forestry productions; imputed value of leisure and labour hiring out activities subject to annual constraints on land, labour and capital availability along with the fulfilment of minimum cash and consumption requirements. The seven scenarios analyzed by the model are: business as usual (BAU), reduction in population growth rate from 2 to 1.5% p.a., increased prices of major crops by 10 and 20%, reduction in emigration of active labour force from the watershed from the current rate of 20–15 and 10%, and increase in discount rate from 5 to 10%. The results indicate that reduced labour emigration rates and increase in the prices of major crops lead to expansion of cultivated area and shift from one land use to the others. Land clearing becomes more severe with decline in labour emigration rate. Up to 10% increase in the prices of agricultural crops does not have noticeable effect on total land clearing. Increase in discount rate leads to less land clearing, more biomass harvesting and higher net C sequestration as compared to the BAU scenario. Assuming a C price of 10 USD per MgC and 5% discount rate, the net present value of C sequestration for the first 25 years is estimated at 1.83 mill USD in the BAU scenario, varying from 0.16 mill USD to 2.26 mill USD, as respectively the lowest and highest values for the seven scenarios analysed. A reduction in population growth and maintenance of current rate of off-farm employment are suggested for slowing down the expansion of cultivated land area, and thereby reducing the forest/soil degradation and C emissions. This in turn would enhance the income potential from C sequestration.     

The Intersectoral Terms of Trade and Their Impact on Urbanisation in China

The historical experience of developed countries shows that the economic development process and accompanying urbanisation represent a structural transformation from an economy dominated by agriculture to one dominated by non-agricultural activities. Therefore it is generally believed that the agricultural sector needs to make a net transfer of resources, both capital and labour, to other sectors in the processes of economic transformation and urbanisation. However, the process of urbanisation in a socialist economy can be negatively affected by its pattern of resource generation. On the basis of an analysis of the 'scissors' pricing mechanism to which the state had recourse for financing its industrialisation, this article argues that this kind of resource transfer did not necessarily favour a high rate of urban employment and urbanisation, regardless of the magnitude of the seizure of resources from the agricultural sector.     

A comparison of specialisation gains from trade in in final and intermediate goods

This paper sets out a method for measuring and comparing the specialisation gains from trade in intermediate goods and final goods, based upon a vertically integrated sectors (VIS) modelling approach. The factor input requirements of domestic production to replace imported intermediates is compared with the factor requirements of the ‘compensating’ exports required to purchase the imports. This method is applied to the UK economy, using a 28 sector model and a breakdown of factor inputs into land, labour and capital. Estimates of net factor-usage or saving on individual factor (weighted for factor quality differences) and multi-factor bases are reported. The results indicate that trade in inputs and outputs was net labour-using, and net-capital and land-saving in 1979. The overall, or multi-factor, gain from trade in intermediates was greater than for trade in final goods in 1979, with overall resource savings of 3·01% and 1·73% respectively.     

SHIFT WORKING AND TRADE IN LABOUR SERVICES WITH TIME ZONE DIFFERENCES

Using a two‐factor (labour and capital), two‐good (shift‐working and non‐shift‐working commodities) model with two countries (Home and Foreign), which are located in different time zones, we highlight the impact of trade in labour services (via communications networks) on the comparative advantage of countries capable of such trade. It is shown that a comparative advantage in a shift‐working commodity is held by pairs of countries in different time zones and connected through a good communication network. Concerning factor prices, if the shift‐working commodity is capital (respectively, labour) intensive, the wage rate for day‐shift labour will decrease (respectively, increase) as a result of trade in labour services. It is also demonstrated that this labour service utilization is mutual: some of Home's day‐shift labour will be utilized for the Foreign night shift, and vice versa. Thus, periodic trade in labour services occurs across countries.     

Markups and bargaining power in tradable and non-tradable sectors

This article jointly estimates product and labour market imperfections for narrowly defined sectors in the Portuguese economy for the period 2006–2009, following Roeger (J Polit Econ 103(2):316–330, 1995), Crépon et al. (Ann Econ Stat (79/80):583–610, 2005), Dobbelaere (Int J Ind Organ 22(10):1381–1398, 2004) and Abraham et al. (Rev World Econ 145(1):13–36, 2009). In addition, we propose a criterion for the identification of tradable and non-tradable sectors based on the export-to-sales ratio and compare markups and workers’ bargaining power along this dimension. Our findings suggest that markups are higher in the non-tradable than in the tradable sector but workers’ bargaining power is similar. In addition, there is a significant level of heterogeneity across markets, particularly in the non-tradable sector. Moreover, the article confirms that, if labour market imperfections are disregarded, markups are significantly understated.     

Spatial Variation in Labour Productivity in British Manufacturing

This paper identifies factors underpinning spatial variation in manufacturing labour productivity in Britain at the county level, examining the relative influences of spatial external effects, the degree of capital intensity, industrial structure, and labour force 'quality'. In doing so, it sets out to test the hypothesis that spatial external economies are not only derived from the immediate environment but also exist over more dispersed areas, such that they can be enjoyed by firms in locations outside major centres. The results show that locational externalities continue to have a very small impact on spatial variation in manufacturing labour productivity in Britain. The really large and instrumental effects arise from variation in capital to labour ratios, industrial structure, and labour force characteristics.     

Strategic Inter–Regional Transfers

We derive the equilibrium level of redistribution from one mobile factor (say, the rich or capital) to another possibly mobile factor (say, the poor or labour) when regions choose both their inter–regional transfers and redistributive policies non–cooperatively. It is shown that inter–regional transfers are always desirable (to mitigate the fiscal competition), but cannot be sustained (as a Nash equilibrium) when chosen simultaneoulsy with the redistributive policy. On the other hand, if regions can pre–commit to inter–regional transfers before setting their redistributive policy, their strategic effect makes efficient inter–regional transfers sustainable. However, there are also equilibria with inefficiently small inter–regional transfers or no transfers at all. The effects of regional asymmetries and additional regions on these results are also analyzed.     

Efficiency and technical progress: sources of convergence in the Spanish regions

The paper analyses the contribution of efficiency as a mechanism of labour productivity convergence, taking as the unit of analysis the Spanish regions in the period 1964–1993. Using the stochastic frontier approach, a translogarithmic production function is estimated for the different sectors of the Spanish regional economy, demonstrating on this basis the existence of substantial differences in efficiency between sectors as well as between regions. With regard to convergence, the results obtained indicate that at aggregate level the convergence observed in labour productivity is explained by the faster growth of the capital-labour ratio of the initially poorer regions and the contribution of technical change and the efficiency, hence by the convergence of TFP. However, the information by sectors shows different results. Thus, on the one hand, the importance of the convergence in production per employee is seen in all sectors except agriculture and, on the other it is observed that technical change is a factor of convergence in all sectors but construction, and, qualitatively, the contribution of technical change is greater than the contribution of efficiency. By sectors, technical change contributed significantly to labour productivity convergence in agriculture, but the faster growth of the capital-labour ratio of the rich regions acted as a mechanism of divergence, completely counteracting the technological catching-up effect. It is further concluded that, as well as the contribution of the accumulation of factors, the positive evolution of efficiency in the poorest regions favoured convergence in the construction and industry sectors, whereas technical progress was decisive in industry and the services sectors.
