The composition of growth matters for poverty alleviation

This paper contributes to explain the cross-country heterogeneity of the poverty response to changes in economic growth. It does so by focusing on the structure of output growth itself. The paper presents a two-sector theoretical model that clarifies the mechanism through which the sectoral composition of growth and associated labor intensity can affect workers' wages and, thus, poverty alleviation. Then, it presents cross-country empirical evidence that analyzes, first, the differential poverty-reducing impact of sectoral growth at various levels of disaggregation, and, second, the role of unskilled labor intensity in such differential impact. The paper finds evidence that not only the size of economic growth but also its composition matters for poverty alleviation, with the largest contributions from unskilled labor-intensive sectors (agriculture, construction, and manufacturing). The results are robust to the influence of outliers, endogeneity concerns, alternative explanations, and various poverty measures.     

The effects of location and sectoral components of economic growth on poverty: Evidence from Indonesia

In this paper, we investigate the relationship between economic growth and poverty reduction by differentiating growth and poverty into their sectoral composition and urban–rural location using data from Indonesia. We find that rural services growth reduces poverty in all sectors and locations. However, urban services growth has the largest effect on poverty in most sectors. Finally, we also find that rural agriculture growth strongly reduces poverty in rural areas, the largest contributor to poverty in Indonesia. This implies that while agriculture growth in rural areas still plays a major role in reducing poverty, policies that enable strong growth in the services sector in both urban and rural areas would expedite poverty reduction.     

Disentangling the Poverty Effects of Sectoral Output,Prices, and Policies in India

This paper attempts to disentangle the poverty effects of key policy variables that directly affect the poor (namely the government‐led channel of development spending and financing) in both agricultural and non‐agricultural sectors after accounting for the effect of respective sectoral per capita income and prices, using data from India over five decades. The paper emphasizes the sectoral composition of income and prices as mechanisms influencing the level of poverty and establishes empirically that it is the rise in non‐agricultural per capita income that reduces rural poverty via the channel of internal migration, after having controlled for the variation in key components of fiscal spending and monetary/financial policy via the availability of credit. Uneven sectoral growth pattern explains why urban poverty becomes a spill‐over of persistent rural poverty when the agricultural sector shrinks. While checking for robustness, there is evidence that the rise in non‐agricultural income alone may not reduce rural poverty, when measured in terms of rural infant mortality rate as a non‐income indicator of well‐being.     

The implications of heterogeneous resource intensities on technical change and growth

Abstract We analyze the long‐term dynamics of an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. It is shown that heterogeneity induces technical change to be biased towards resource‐intensive sectors. Along the balanced growth path, the sectoral structure of the economy is constant as the higher resource dependency in resource‐intensive sectors is compensated by enhanced research activities. Resource taxes have no impact on dynamics except when the tax rate varies over time. Research subsidies and the sectoral provision of productivity‐enhancing public goods raise growth and provide an effective tool for structural policy.     

Technological leadership and sectorial employment growth: A spatial econometric analysis for U.S. counties

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.     

Why is TFP growth sectorally concentrated?

Research shows that total factor productivity (TFP) growth is weak in European countries. This is inter alia attributed to the fact that substantial TFP growth is limited to a few industries. Because TFP growth is typically understood as technological progress, it is concluded that technology diffusion between sectors in Europe is hampered. We use EU KLEMS data sets to decompose sectoral TFP for nine European countries by means of a Malmquist approach in order to identify potential sources besides technical progress. Applying Harberger diagrams, we describe the sectoral distribution of TFP growth, efficiency gains and losses, economies of scale and technological progress. The analysis reveals that technological progress is quite evenly distributed across sectors in most European countries. The wide scattering of TFP growth is explained by deviating efficiency developments and the unused economies of scale. We conclude that the technology transfer between sectors in most European countries seems to work. Therefore, Europe in general does not need a new technology policy, but a further integration of the markets and a reduction of national market entry barriers. This requires further unification of pan-European standards in fields like trade and crafts codes or consumer protection policies.     

Economic growth,the nature of growth and poverty reduction in rural China

This paper examines some of the major driving forces of poverty reduction in China. Based on time series and cross-sectional provincial data, the determinants of rural poverty incidence are estimated. The results show that economic growth is an essential and necessary condition for nationwide poverty reduction. It is not, however, a sufficient condition. While economic growth played a dominant role in reducing poverty through the mid-1990s, its impact has diminished since that time. Beyond general economic growth, growth in specific sectors of the economy is also found to be effective in reducing poverty. The finding of our paper is consistent with the idea that poverty reduction in the future will need to be adjusted with more emphasis being given on direct targeting through helping the poor to increase their human capital and incomes.     

The Efficiency of Active Labor Market Policies: A Comparative Analysis of Tunisia and OECD Countries’

ABSTRACT

On the third anniversary of the Egyptian revolution and against the backdrop of lingering political instability and deteriorating economic conditions, we diagnose the constraints to sectoral growth in Egypt using the 2011 Egyptian revolution as a natural experiment. We combine quantile regressions to study sector outliers with a difference in difference methodology to capture sectoral behavior before and after revolution. We find that the revolution's effect has been adverse, on average, but heterogeneous across sectors. We identify and characterize sectors most and least impacted. Results reveal that Egypt's fastest growing sectors before Revolution have been the most vulnerable after Revolution. This evidence is supported by our diagnosis approach that shows that faster growing sectors are constrained by continuous increases in prices that threaten export competitiveness (as they erode the benefits accrued to nominal depreciation of currency). Such sectors also benefited from higher monetary growth and fewer constraints on credit availability that have mitigated somewhat the speed of deterioration in the aftermath of the revolution. Our results, which hold under several robustness checks, inform policy priorities as to how to revive investors’ confidence, boost competitiveness, and design priorities in industrial policy to ease structural impediments and align sectoral growth with macro priorities.     

Optimal Monetary Policy and Sectoral Shocks: Is International Monetary Cooperation Beneficial?

A stochastic general‐equilibrium model is used to explore the welfare effects of optimal monetary policy and the potential benefits of policy coordination. Cross‐country perfectly symmetric shocks in the traded goods sectors and imperfectly correlated shocks in the non‐traded goods sectors are considered. In this set‐up, monetary policy may not be able to achieve efficient sectoral resource allocations within countries and avoid inefficient relative price changes across countries. Welfare gains from coordination are sizable if the shocks to the traded and non‐traded goods sectors are negatively correlated and both sectors are of roughly equal size.     

Global Sourcing in Industry Equilibrium

This paper extends the Antràs and Helpman (2004) model to a continuum of sectors to explore a full set of possibilities for organizational forms in global sourcing. We show that industries of the economy are divided into seven classes of sectors in terms of the prevalence of organizational forms. In particular, the coexistence of different organizational forms is less likely as the sectoral input intensity is more extreme, so that intra‐industry heterogeneity is less relevant to the firms' organizational choices. It is also demonstrated that our equilibrium analysis offers a useful framework for examining comparative statics on the sectoral input intensity.     

The distributive impact of terms of trade shocks: The case of the oil price changes in Russia

The halving of oil prices, during a short period between 2014 and 2015, has generated major terms of trade losses for oil exporting countries. This terms of trade shock has economy‐wide effects and significant distributive impacts. This paper, using a macro‐micro simulation model, describes and quantifies the channels of transmission from the drop of oil prices, to changes in welfare distribution at the household level for the case of the Russian Federation. The oil price reduction generates a reverse Dutch disease impacting sectoral employment, factor returns and consumption prices. It causes a contraction of employment and wages in more skill‐intensive (non‐tradable) sectors, and a reduction in consumption prices that is more pronounced for non‐food than for food goods. When these shifts are mapped to changes in incomes at the micro level, all households are affected. Poverty rates increase by 1 to 4 percentage points, depending on the poverty line used. At the US$ 10 a day threshold, 4.1 million additional people fall into poverty. Along the consumption distribution, richer people are affected more than those in the bottom 40%. However, this minor progressive impact may be reversed due to increases in unemployment and cuts in social programmes.     

Sectoral regularities of productivity growth in developing countries--a Kaldorian interpretation

This paper provides a Kaldorian interpretation for empiricalregularities of productivity growth at the sectoral level ofthe economy. The statistical evidence is based on a datasetdrawn from internationally compatible time series for employmentand value added in 30 developing countries. Based on novel non-linearstatistical techniques the findings show: (i) a regular patternof positive sectoral employment elasticities with respect tooutput growth; (ii) robust differences across sectors in themagnitude of the employment elasticities; and (iii) employmentelasticities for all sectors that are significantly less thanunity, suggesting strong evidence for increasing returns atthe sector level of the economy.     

A Sectoral Approach Balancing Global Efficiency and Equity

This paper explores the idea that a properly designed sectoral approach could be the answer to two sets of constraints that hinder international agreements on climate change, namely a genuine concern from developing countries for economic growth and competitiveness issues from industrialized countries. Our sectoral approach builds on three premises: (i) cap-and-trade systems are established in industrialized countries and intensity targets in developing countries, (ii) sectors subject to international trade abide by the rules of the countries in which they trade and (iii) a fraction of the revenues from permits in industrialized countries go towards carbon mitigation in developing countries. We design an economic model that features interactions in three carbon-intensive sectors (two of which are internationally traded) and two countries (an industrialized country and a developing country). Two scenarios are constructed: an Enhanced Sectoral Approach, which refers to our proposal, and a Global Cap, which implements a uniform CO₂ price. We compare the two scenarios in terms of total welfare and equity. It is shown that, for a minor global welfare loss, the Enhanced Sectoral Approach ranks high in terms of equity for emerging countries. This approach also eliminates competitiveness and leakage issues.     

Impact of trade liberalisation on labour market and poverty in Sri Lanka. An integrated macro-micro modelling approach

This paper revisits the long standing controversy of trade and poverty linkage using a macro-micro modelling approach based on general equilibrium and microsimulation analytical frameworks. Sri Lanka, the first country in South Asia which undertook trade reforms more than three decades ago, is taken as a case in point in this study. The paper analyses the effects of trade liberalisation on income distribution and poverty in the urban, rural and estate sectors in Sri Lanka using the first ever microsimulation model built for the country in combination with a multi-household computable general equilibrium (CGE) model. The results reveal that without any fiscal policy adjustments a 100% tariff cut would lead to an increase in economic growth and a reduction in poverty incidence both in the short run as well as in the long run. However, when the tariff cut combined with the fiscal policy adjustments to maintain the budget neutrality, poverty outcomes showed mixed results. In contrast, results show that trade liberalisation increases the income inequality in Sri Lanka.     

How best to link poverty reduction and debt sustainability in IMF–World Bank models?

This paper attempts to provide an economic model in the context of developing countries to address the policy strategies related to poverty reduction. With a view to deal with the shortcomings of the existing approaches as regards poverty reduction, this paper develops a model on the basis of the policy framework of the IMF and the World Bank to show how demand growth can be a crucial mechanism in determining the potential rate of growth, and then to suggest ways in which poverty—conceptualised officially in absolute terms with a subjective cut‐off point (e.g. US $1/$2 a day), and a new objective measure in terms of consumption deprivation—can be linked with the key policy variables contained in the adjustment programmes. A strategy of investment in infrastructure and in human development, and improving access to credit markets, particularly in rural areas to encourage or ‘crowd in’ private investment is a precondition for growth and poverty alleviation. Debt relief can only provide a temporary, not a sustainable, solution to the problem of reducing poverty.     

Agricultural Productivity and Poverty Reduction in Nepal

This paper provides for the first time a clear quantitative link between agricultural productivity and poverty among rural households in Nepal. Using data from a nationwide Nepal Living Standard Survey 2004, we first estimate household‐specific productivity per worker under both Cobb–Douglas and translog production functions. Second, the paper identifies the determinants of productivity. Third, we explore a theoretical link between productivity and poverty using Sen's poverty index and find empirically that productivity growth substantially helps poverty reduction. Finally, the integrated effects of changes in productivity determinants are found to be stronger than the outcomes of sectoral policies taken in isolation.     

Foreign direct investment and inequality in developing countries: Does sector matter?

Scholars have studied the relationship between inward foreign direct investment (FDI) and within‐country income inequality in cross‐national contexts, but have not empirically investigated how FDI in different sectors might affect inequality in different ways. We use error correction models to analyze sectoral FDI data compiled from UNCTAD investment reports in 60 middle‐income countries from 1989 to 2010, arguing that FDI in services is more likely to be associated with inequality than FDI in other sectors. We argue that skill biases and changes in employment patterns associated with service sector investments can help explain these findings.     

Sectoral and aggregate technology growth in Spain

In this paper we analyze technological change in the Spanish economy by constructing adjusted Solow residuals, where the adjustment attempts to correct for the bias associated with the potential presence of imperfect competition, increasing returns, variable input utilization and, especially, sectoral reallocation of inputs across sectors. We refer to this modified Solow residual as a technology index. Sectoral reallocations and variable input utilization are key determinants of the differences between the aggregate Solow residual and the technology index resulting from the aggregation of estimated sectoral technological growth. We show that starting in the mid nineties, there has been a deceleration in the aggregate growth rate of technology which is basically due to the behaviour of the manufacturing sectors. Finally, our results imply that aggregate technology growth is less volatile than aggregate productivity as measured by the Solow residual.     

A two-sector Kaleckian model of growth and distribution with endogenous productivity dynamics

This study extends a two-sector Kaleckian model of output growth and income distribution by incorporating endogenous labour productivity growth. The model is composed of investment goods and consumption goods production sectors. The impact of a change in wage and profit shares on capacity utilisation and output growth rates at the sectoral and aggregate levels are identified. The study reveals short-run cyclical capacity utilisation rates and productivity growth dynamics. Even if the short-run steady state is stable, the capital accumulation rate in the consumption goods sector must decrease more than that in the investment sector for long-run stability. When simultaneous rises in profit shares in both the sectors affect long-run aggregate economic growth differently at a steady state, the distributional interests between the same class in different sectors may hamper the long-run economic growth. A policy message is that the effect of income distribution on industrial output growth is not always beneficial. These phenomena are specific to two-sector models and cannot be observed when using conventional aggregate growth models.     

Micro and macro dynamics: Industry life cycles,inter-sector coordination and aggregate growth

Technological change directly affects economic growth by exploiting and exploring technological opportunities, thus determining productivity growth and income. However, technological change also affects the composition of the economic system, which itself constitutes an important prerequisite for economic growth. The first aim of this paper is to show that the growing variety of the economic system, determined by the emergence of new products and services and leading to new industrial sectors, can allow the long term continuation of economic development, even when the employment creating capacity of individual sectors falls. The second aim is to illustrate the impact of micro variables on the meso-level, that is, on the sectoral composition of an economy, as well as on its macro-economic performance.
