Estimates of the impact of COVID-19 on global poverty

Abstract: In this paper we make estimates of the potential short-term economic impact of COVID-19 on global monetary poverty through contractions in per capita household income or consumption. Our estimates are based on three scenarios: low, medium, and high global contractions of 5, 10, and 20 per cent; we calculate the impact of each of these scenarios on the poverty headcount using the international poverty lines of US$1.90, US$3.20 and US$5.50 per day.

International Development Studies: Theories and Methods in Research and Practice

Abstract: This book is an exploration of what it is to 'do' development studies as a distinct discipline. It introduces and addresses the fundamental questions that everyone engaged with development - whether student, researcher, or practitioner. Accessibly written, with extensive use of case study material, this book is an essential primer for students of development studies who require a concise, penetrating overview of its foundations.

Global Poverty and the New Bottom Billion: What if Three-quarters of the World's Poor Live in Middle-income Countries?

Abstract: Summary This paper argues that the global poverty problem has changed because most of the world's poor no longer live in low income countries (LICs). Previously, poverty was viewed as an LIC issue predominantly; nowadays such simplistic assumptions/classifications are misleading because some large countries that graduated into the MIC category still have large numbers of poor people. In 1990, we estimate 93 per cent of the world's poor lived in LICs; contrastingly in 2007–8 three quarters of the world's poor approximately 1.3bn lived in middle-income countries (MICs) and about a quarter of the world's poor, approximately 370mn people live in the remaining 39 low-income countries – largely in sub-Saharan Africa. This startling change over two decades implies a new ‘bottom billion’ who do not live in fragile and conflict-affected states, but in stable, middle-income countries. Such global patterns are evident across monetary, nutritional and multi-dimensional poverty measures. This paper argues the general pattern is robust enough to warrant further investigation and discussion.

What is Development Studies

Abstract: This article is concerned with some initial reflections on the distinctive features of Development Studies (DS). The aim is to trigger further debate, rather than attempt ‘closure’. Discussion of the nature of DS is timely because of the expansion of taught courses at various levels during the previous decade; because of sustained critiques of DS in recent years; and because DS has entered a period of introspection – illustrated by several journal special issues and events – to identify its defining characteristics. The author argues that DS is a worthwhile endeavour (how could a concern with reducing global poverty not be?), but the field of enquiry needs to think about how it addresses heterogeneity in the ‘Third World(s)’ and how it opens space for alternative ‘voices’.

Climate Change 2007: Impacts, Adaptation and Vulnerability.

Abstract: Impatti, adattamento e vulnerabilita Le cause e le responsabilita dei cambiamenti climatici sono state trattate sul numero di ottobre della rivista Cda. Approfondiamo l’argomento presentando il documento: “Cambiamenti climatici 2007: impatti, adattamento e vulnerabilita” votato ad aprile 2007 dal secondo gruppo di lavoro del Comitato Intergovernativo sui Cambiamenti Climatici (Intergovernmental Panel on Climate Change). Si tratta del secondo di tre documenti che compongono il quarto rapporto sui cambiamenti climatici.

Economic growth and income inequality

Abstract: We investigate whether income inequality affects subsequent growth in a cross-country sample for 1965-90, using the models of Barro (1997), Bleaney and Nishiyama (2002) and Sachs and Warner (1997), with negative results. We then investigate the evolution of income inequality over the same period and its correlation with growth. The dominating feature is inequality convergence across countries. This convergence has been significantly faster amongst developed countries. Growth does not appear to influence the evolution of inequality over time. Outline
