Not by growth alone: The role of the distribution of income in regional diversity in poverty reduction

This study examines the role of the distribution of income in determining the responsiveness of poverty to income growth and changes in income inequality using panel data of 58 developing countries for the period 1980-1998. We show that the large cross-regional variation in the capacity of income growth to reduce poverty, i.e. the income elasticity, is largely explained by differences in the initial distribution of income and present region and time specific estimates of the income and Gini elasticities of poverty. We find that the income elasticity of poverty in the mid-1990s equals −1.31 on average and ranges from −0.71 for Sub-Saharan Africa to −2.27 for the Middle East and North Africa, and that the Gini elasticity of poverty equals 0.80 on average and ranges from 0.01 in South Asia to 1.73 in Latin America. Furthermore we show that while differing income growth rates account for most of the regional diversity in poverty trends, the additional impact of differences across regions in rates of inequality change and income and inequality elasticities of poverty is almost always significant and far too large to be ignored, most notably so in Eastern Europe and Central Asia.     

The Neolithic Revolution from a price-theoretic perspective

The adoption of agriculture during the Neolithic period triggered the first demographic explosion in history. When fertility returned to its original level, agriculturalists were more numerous, more poorly nourished, and worked longer hours than their hunter-gatherer ancestors. We develop a dynamic price-theoretic model that rationalizes these events. In the short run, people are lured into agriculture by the increased labor productivity of both adults and children. In the long run, the growth in population overrides the productivity gains, and the later generations of agriculturalists end up being worse-off than the hunter-gatherers. Counter-intuitively, the increase in the labor productivity of children causes the long-run reduction in welfare. In the long run, the increase in adult labor productivity only contributes to population growth.     

Corruption and local democratization in Indonesia: The role of Islamic parties

Indonesia has a tradition of corruption among local officials who harass and collect bribes from firms. This paper examines whether corruption is affected by local democratization and by the party composition of local assemblies. Democratization occurred in 1999 and decentralization in 2001. We have firm-level data for 2001 and 2004. The 2001 data benchmark corruption at the time of decentralization. We find that corruption declines between 2001 and 2004 overall, but much less so in districts with more secular party as opposed to Islamic party representatives in district assemblies. For a larger sample of districts, correspondingly, we find that corruption in 2004 is more in districts which voted more in favor of secular party representatives in the first elections in 1999. We argue that the effects seem to be causal, over above any effects of changing religiosity and economic circumstances across districts.     

Confronting the risk of asset loss: What role do livestock transfers in northern Kenya play?

In many low-income, high-risk environments households participate in informal risk sharing institutions involving inter-household transfers. This study focuses on: asset transfers and asset risk; the influence of past behavior on access to transfers; and wealth-differentiated transfer behavior. Panel data on livestock transfers in northern Kenya are analyzed. Three explanations of livestock transfers are investigated: ex post insurance; ex ante precautionary savings; and redistribution. Findings indicate that livestock transfers are of limited effectiveness in addressing asset risk and avoiding poverty. The findings have implications for both research on risk sharing institutions and for the design of development policies in pastoral areas.     

The democratization process: An empirical appraisal of the role of political protest

This paper analyses the role of peaceful and violent protest in the democratization process. We interpret the democratization process as a sequence of phases so as to allow citizens' and elites' preferences for democracy to vary according to the particular phase that a country is experiencing. By doing so we jointly model the probability of protest and of moving through different phases of democracy taking into account time-constant and time-varying unobserved heterogeneity. In particular, we develop a multivariate finite mixture model that introduces a latent variable to capture unobservable factors. On a sample of 171 countries from 1971 to 2010, we provide evidence that protest matters in all phases of democratization, especially peaceful citizens’ demonstrations. On the contrary, violent protest has ambiguous consequences, as it favours initial democratic transitions but at the cost of threatening democratic consolidation. We also find that, after conditioning for economic and institutional controls, there is evidence of time-varying unobserved heterogeneity.     

Redistribution, fertility, and growth: The effect of the opportunities abroad

This article analyzes the effect of the opportunities abroad on the growth path that a small open economy, in which redistribution policy in favor of less prosperous segments takes place, is expected to follow. The model shows that redistribution policy raises fertility among the unskilled recipients, lowers fertility among the contributing skilled, slows human capital accumulation, and reduces per-capita output growth. The paper demonstrates that the opportunities abroad determine the share of income redistributed and ultimately induce the offspring of the unskilled to invest in human capital and decrease their family size.     

The role of networking in the competitiveness of firms

Two main forces characterise production systems today: on the one hand, the increasingly global nature of markets and economies has resulted in increasing competition and a new, more global division of labour. On the other, the greater complexity of technology makes innovation a key aspect in the competitiveness of manufacturing firms. The establishment of cooperative networks seems to be important in both processes. This paper aims to explore these aspects by analysing the competitiveness of firms in four different sectors of the manufacturing industry: food, chemicals, electronics and vehicles. Data have been obtained from a survey conducted specifically for this purpose at company level in Spain. Findings from the empirical analysis, based on the application of the Polytomous Logistic Universal Model (PLUM), confirm the positive effects that the ability to network has on company performance. In particular, among all the potential organisations that work as partners of the firms, the paper shows the importance of intra-firm cooperation, the user-producer relationships and the cooperation between competitors.     

Consumption versus asset smoothing: testing the implications of poverty trap theory in Burkina Faso

Despite solid theoretical foundations for the notion that poor, borrowing-constrained households will intertemporally manage assets to smooth consumption, the consumption-smoothing hypothesis has not always withstood empirical scrutiny. This paper reassesses the intertemporal asset management problem with a poverty trap model and shows that we would expect to see asset smoothing, not consumption smoothing, in the neighborhood of critical asset levels at which optimal accumulation behavior bifurcates. We then employ threshold estimation techniques to empirically confirm the co-existence of consumption and asset smoothing regimes using a household panel data set from West Africa. Households above the estimated threshold almost completely insulate their consumption from weather shocks, whereas those below the threshold do not. These results not only indirectly provide evidence of the existence of poverty traps but also speak to the level and incidence of the costs of uninsured risk.     

Regional convergence of growth,inequality and poverty in India—An empirical study

The paper attempts to examine whether there is regional convergence of per capita consumption, inequality and poverty across various states in India. Using panel unit root tests that are robust to cross-sectional dependence, we find that inequality and poverty indicators converge at both rural and urban levels. Further, per capita consumption converges at urban level but not at rural level. Based on factor analysis, we find two groups of states for rural sectors, viz., low-growth and high-growth states, for each of which per capita consumption converges. We also attempt at identifying the responsible entities — central or state governments or both in cases where convergence is not achieved.     

The relative weight of manufacturing and services in Europe: An innovation perspective

This paper uses an innovation-based taxonomy of both manufacturing and service industries to assess the role of the process of structural change of the last 25 years on the rate of productivity growth in Europe, US and Japan. The empirical analysis exploits the shift-share methodology for a decomposition of aggregate labor productivity growth. A modified version is applied, that allows to interpret whether employment has shifted to higher or lower productivity sectors. The results are discussed in light of the role that the different industries play according to the innovation-based taxonomy.     

An aspect of variable population poverty comparisons

This paper demonstrates that the property of Replication Invariance, generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variable- and fixed-population axioms. This fact raises questions about what constitutes an appropriate headcount assessment of poverty, in terms of whether one should focus on the proportion, or the absolute numbers, of the population in poverty. This observation, in turn, has important implications for tracking poverty and setting targets for its reduction or elimination.     

External factors in emerging market recoveries: An empirical investigation

We estimate conditional duration models to analyse recovery processes in emerging market economies. Our reduced form specification is parsimonious, as we focus on exogenous factors, such as the effect of growth in the US, EU, and Japan on the prospects for recovery in emerging market economies experiencing recessions. The model confirms the importance of external factors in recovery processes. However, the short-run effect of Japanese growth on recovery prospects is unconventional: weak economic conditions in Japan turn out to facilitate recoveries.     

The Paretian Ratio Distribution — An application to the volatility of GDP

Recently, Gabaix suggested that the volatility of GDP could come from the Pareto distribution of the firm sizes. This paper describes and gives an approximation of the Paretian Ratio Distribution (PRD), which represents the weight of the firm in GDP.     

Investment in the absence of property rights; the role of incumbency advantages

In many situations the individuals who can generate some output must enter a contest for appropriating this output. This paper analyses the investment incentives of such agents and the role of incumbency advantages in the contest. Depending on the advantages, an increase in the productivity of the investment can decrease or increase the amount of investment. The results are applied to autocrats’ investment behavior and job specific investment in organizations.     

Growth and convergence in South–South integration areas: An empirical analysis

Until recently, it has been argued in economic theory that regional integration and trade agreements among developing countries may achieve negative growth effects. This study tests empirically the effects of such South–South agreements on growth and convergence. All three world regions in question are considered: South America, Southeast Asia, and Sub‐Saharan Africa. A comprehensive panel data analysis is conducted that distinguishes between the problems of testing for stronger growth and accelerated convergence, respectively. The data indicate that the considered South–South agreements promote both.     

Natural resource extraction and civil conflict

Based on evidence linking natural resources to civil conflict, this paper studies two armed groups fighting to control a resource and possibly a second prize. Labor is used in the agricultural, resource extraction and conflict sectors, and the groups also buy a capital input to conflict subject to the constraint that capital spending cannot exceed resource earnings. I find that exogenous shocks can have different effects on conflict intensity depending on whether the credit constraint binds. In particular, international policies to ban natural resource exports from conflict zones (e.g. ‘blood diamonds’), raise agricultural productivity or limit the import of weapons will limit conflict intensity if the credit constraint binds. However, if the credit constraint does not bind, then the first two policies promote conflict, and so could even the third policy. The results therefore suggest some caution in international policymaking.     

Equity-regarding poverty measures: differences in needs and the role of equivalence scales

Abstract .  The paper investigates the definition of equity-regarding poverty measures when there are different household types in the population. It demonstrates the implications of a between-type regressive transfer principle for poverty measures, for the choice of poverty lines, and for the measurement of living standard. The role of equivalence scales, which are popular in empirical work on poverty measurement, is clarified.
