Evolutions in Consumption Inequality and Poverty in Greece: The Impact of the Crisis and Austerity Policies

Greece is the country hit hardest by the crisis and subsequent fiscal consolidation strategies, suffering a cumulative output loss of about 30 percent since 2008. The present paper presents evidence that along with declining average living standards, consumption inequality has seriously grown, fueled primarily by a disproportionate drop in the consumption levels of what can be considered the middle class. Although poverty has not significantly risen in relative terms, it climbs to around 45 percent once the poverty threshold is anchored to pre‐crisis levels. Furthermore, significant indirect tax hikes have further increased inequality in consumption expenditure. The paper also shows that several reforms launched in the name of reducing labor costs, broadening the tax base or rationalizing the targeting of social benefits have had detrimental effects on one of the most vulnerable population groups, namely families with children, thus implying that the social consequences of the crisis will be long‐lasting.     

Globalisation,poverty and corruption: Retarding progress in South Africa

ABSTRACT

Poverty and corruption can both immiserate a nation. Globalisation through open trade can potentially increase economic growth, providing employment and increased incomes to the poor. Corruption can dampen or even reduce these positive developments. Although globalisation is considered instrumental in development strategies, theoretically, the impact of globalisation on poverty reduction is ambiguous, an ambiguity that is also reflected in the empirical literature. The corruption-poverty literature clearly reveals that empirical findings on such association are at best heterogeneous. This article examines the effects of globalisation and corruption on poverty using time series data for South Africa for the period 1991–2016. Three indicators of poverty and recently developed measures of globalisation and corruption were employed in the logistic regression model used for estimation. The results confirm that globalisation reduces poverty while corruption intensifies it. The globalisation findings are robust across the different measures of poverty while unidirectional results show corruption increases poverty.     

Supermarket contracts and smallholder farmers: Implications for income and multidimensional poverty

Food systems in developing countries are changing rapidly with a growing role of modern supermarkets. Supermarkets influence supply chains and the way agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent and high-quality supply. One important question, which is addressed here, is whether smallholder farmers benefit from supermarket contracts. Previous studies address this question, but mostly focus on income effects without exploring implications for other dimensions of household welfare, such as nutrition, health, or housing conditions. Moreover, most existing studies rely on cross-section data. We add to the literature by analyzing effects of supermarket contracts on income and multidimensional poverty using three rounds of panel data collected from smallholder vegetable farmers in Kenya and econometric models with household fixed effects. On average, supermarket contracts increase household income by over 40%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. However, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.     

Do crop purchase programs improve smallholder welfare? The case of Zambia's Food Reserve Agency

Government and parastatal crop purchase programs have regained popularity in sub-Saharan Africa, with many citing improving smallholder farmers’ welfare as a key goal. Yet there is limited empirical evidence on the topic. This paper analyzes the effects of the Zambian Food Reserve Agency's (FRA's) maize purchase activities on smallholder welfare. The FRA buys maize at a pan-territorial price that often exceeds market prices in surplus production areas. Using two household panel survey datasets spanning 15 years and exploiting variation in the scale of FRA activities over time, we employ fixed effects and control function approaches to estimate the effects of a smallholder household's maize sales to the FRA on its welfare, as well as the effects of more intense FRA maize purchase activity in a given district on the welfare of smallholder households in the district. Results suggest positive direct welfare effects on the minority of smallholders that sell to the FRA. We also find that, in the early years of the program, more intense FRA maize purchase activity in a district was associated with reductions in smallholder welfare, particularly among maize autarkic and net buying households. In later years, we find no evidence of such negative effects and some evidence of positive district-level effects on maize net buyers.     

Poverty analysis in the lowlands of Papua New Guinea underscores climate vulnerability and need for income flexibility*

A severe El Niño event in 2015/16 decimated an important share of Papua New Guinea's (PNG) local crop production, leaving 10 per cent of the population with significant food shortages. Lack of recent socio‐economic data and analysis of the country's rural population impeded efforts to plan and mitigate the ensuing food crisis. This paper presents the most recent poverty analysis in Papua New Guinea in nearly a decade, and a renewed effort to inform rural production, consumption and livelihood patterns in some of the country's most remote, lowland areas. We designed a rural household survey that collected detailed consumption and expenditure data to explore poverty prevalence and correlates of per capita household expenditure. Results suggest that approximately half of the sampled individuals live in households with total per capita expenditures below the poverty line. Climate shocks have significant and possibly long‐term consequences for household welfare. Households that experienced a drought in the last 5 years are associated with significantly lower per capita expenditures. Labour diversification, via migration, is associated with greater welfare. Households with at least one migrant member are associated with 13 per cent greater per capita expenditure.     

Poverty volatility and poverty in developing countries

This article examines the effect of poverty volatility on poverty in developing countries. Poverty volatility refers to the amplitude of the change in poverty rates over a given period of time. Variations in poverty rates can potentially arise from countries' vulnerability to a variety of shocks that induce greater macroeconomic volatility, including economic growth volatility. The empirical analysis shows that poverty volatility consistently induces a rise in poverty rates, and this positive poverty effect of poverty volatility increases as the degree of poverty volatility rises. Policies that help reduce poverty volatility (including by dampening economic growth volatility) would contribute to poverty reduction.     

Cure-all or curse? A meta-regression on the effect of tourism development on poverty alleviation

The purpose of this study is to synthesize the overall effect size of tourism on poverty alleviation and to unveil underlying factors explaining the heterogeneity of this effect size across estimates. Using a rigorous meta-analysis based on 298 estimates extracted from 33 studies, we calibrate a combined effect size of −0.14 with a 95% confidence interval of [-0.23, −0.05], indicating that tourism moderately reduces poverty. A meta-regression demonstrates that the effect size of the tourism–poverty nexus is susceptible to several factors, such as poverty and tourism measures, focal countries’ development level, and endogeneity treatment. In particular, the results show that use of the Gini coefficient, a popular proxy for the poverty gap, can unexpectedly underestimate the negative effect size. Moreover, funnel plot and Galbraith plot demonstrate that researchers are apt to report a positive tourism–poverty nexus in the literature. Lastly, research and policy implications are provided.

Environmental Quality,Income Distribution,and Factor Mobility: The Consequences of Local Action

This paper discusses the regressive nature of tax exemptions for children compared to child allowances and estimates the decline in child poverty in several developed countries due to child allowances. The paper then estimates the decline in child poverty in the United States due to tax exemptions for children and simulates the impact of various possible child allowance programs on child poverty in the United States. It finds that a $3000 to $4000 child allowance would reduce child poverty in the United States to the level of other developed nations and, due to the costs associated with child poverty, be a cost effective policy change.     

A panel data test for poverty traps

This article develops a threshold panel data nonlinearity test for poverty traps. The new testing strategy extends the work on nonlinearity tests for panel data by considering threshold nonlinearities in the fixed-effects components. Monte Carlo simulations are conducted to evaluate the finite-sample performance of these tests. The tests are applied to the relationship between Gross Domestic Product (GDP) per capita and capital stock per capita. Our application to a panel of countries for the period 1973 to 2007 uncovers the presence of two regimes determined by the level of capital stock per capita. The conclusions from our test also support the existence of a poverty trap determined by a capital stock per capita level at the 11% quantile of its pooled worldwide distribution.
