This note, which forms part of a series of technical notes that complement Lastunen et al. (2021), reports the approach used to derive shocks to household expenditures from shocks at the individual-level labour incomes. Its structure is composed by...
This note sets out two different methods on how to adjust incomes in the microdata underlying the standard SOUTHMOD models to reflect a sudden shock, in this case the COVID-19 shock, as done in the accompanying working paper by Lastunen et al. (2021)...
This paper proposes a decomposition framework for quantifying contributions of the determinants of poverty to spatial differences or temporal changes in poverty. This framework is then applied to address the issue why poverty incidence is higher in...

China’s recent accession to the WTO is expected to accelerate its integration into the world economy, which aggravates concerns over the impact of globalization on the already rising inter-regional income inequality in China. This paper discusses...
Using new household survey data for 1995 and 2002, we investigate the size of China’s urban-rural income gap, the gap’s contribution to overall inequality in China, and the factors underlying the gap. Our analysis improves on past estimates by using...
While the average level of income per capita has increased in China rapidly, income inequality is becoming a more serious problem that may threaten social stability and the sustainability of economic development. This paper examines the existence in...
This paper examines the impact of income risk on the level of well-being of rural households in Nigeria. While income risk is defined as the risks associated with variability in income well-being is defined in terms of the level of utility reached by...
This study traces the interactions between economic growth, income inequality and consumption poverty in a sample of African countries during the 1990s. It draws on the much-improved household data sets now available in the region. It finds that...

Volatility in commodity markets poses a distinct risk to farmers in developing countries who rely on cash crop agriculture. We combine a time series of international coffee prices with a long-running panel on coffee-growing households in Vietnam to...
In this paper we address the issues involved with the use of microeconomic data, that is, household surveys, to compare the patterns of income growth among different regions instead of the commonly used aggregate data. In particular, we investigate...
The paper tests for external effects of local economic activity on consumption and income growth at the farm household level using panel data from four provinces of post-reform rural China. The tests allow for nonstationary fixed effects in the...

Studies of the inter-recipient allocation of aid may be categorized threefold. First, there are those which attempt to explain the observed allocation of aid. Second, there are those which seek to describe or evaluate the allocation of aid against...
This paper tests using survey data from China whether individual health is associated with income and community-level income inequality. Although poor health and high inequality are key features of many developing countries, most of the earlier...
Volatility in commodity markets poses an acute risk to farmers in developing countries who rely on cash crop agriculture. We combine a time series of international coffee prices with a long-running panel on coffee-growing households in Vietnam to...
Absolute poverty lines are often derived from the cost of obtaining sufficient calories. Where staples vary across regions, such poverty lines may differ depending on whether they are set using national or regional food baskets. Regional poverty...
Over the years, money-metric measures of inequality such as the Gini coefficient and the Palma Ratio, as frequently used in Ghana, have become useful in providing quantitative measures of welfare distribution that enable a better understanding of the...
This technical note describes the Uganda Revenue Authority (URA) Pay-As-You-Earn (PAYE) data covering financial years 2013/14 to 2021/22. PAYE is paid by an employer who withholds personal income tax on employees’ wages and other employment incomes...

Changes in relative prices of commodities consumed in different shares across income groups can be expected to alter real income differentials between these groups. Using Mozambican household budget survey and price data from 2002/03 and 2008/09, we...
South Africa has seen a significant increase in the size of the black middle class in the post-apartheid period, but the attitudinal consequences of indicators of the middle class, as of 2011, are inconsistent and modest in size. While members of the...
Changes in the relative prices of commodities consumed in different shares across income groups are known to influence real measures of inequality. Using household budget survey and price data in Mozambique from 2002/03 and 2008/09, we show that...
This paper seeks to measure and explain changes in incomes, inequality, and poverty in Kenya. It starts from a very long-term perspective covering the last century, but then focuses on a more detailed analysis of the recent period for which data from...
This paper presents new evidence on the study of income mobility in Ecuador over the period 2004–11. We utilize longitudinal data of individual income tax returns to measure income mobility both at the top and at the middle of the income distribution...
We reconcile, both theoretically and empirically, changes in inequality with panel income changes over periods of economic growth and decline. We also explore what factors account for the trends of short-run inequality and of inequality in individual...
This paper investigates inequalities across the major black ethnic groups in South Africa, accounting for 80 per cent of the country’s population. We demonstrate that there is an important ethnic gap in the poverty levels of the Xhosa and the Zulu...
