Working Paper
pdf
Social scientists are increasingly engaging in experimental research projects of importance for public policy in developing areas. While this research holds the possibility of producing major social benefits, it may also involve manipulating populations, often without consent, sometimes with...

– Definitions and Diagrams
The fundamental problem of external validity is not to generalize from one experiment, so much as to experimentally test generalizable theories. That is, theories that explain the systematic variation of causal effects across contexts. Here we show how the graphical language of causal diagrams can...
Working Paper
pdf
In recent years, randomized controlled trials have become increasingly popular in the social sciences. In development economics in particular, their use has attracted considerable debate in relation to the identification of ‘what works’ in development policy. This paper focuses on a core topic in...
Working Paper
pdf
– Opportunities and Challenges
‘Ancillary experiments’ are a new technique whereby researchers use a completed experiment conducted by others to recover causal estimates of a randomized intervention on new outcomes. The method requires pairing new outcome data with randomized treatments the researchers themselves did not oversee...

– Towards Experiments?
In examining the study of government performance, this paper asks whether field experiments can improve the explanatory precision of results generated by public opinion surveys. Survey research on basic health and education services sub-Saharan Africa shows that the perceived ‘user friendliness’ (or...

– Its Design and Use for International Development Policy
In response to the need expressed by the UN General Assembly, an economic vulnerability index (EVI) has been defined by the Committee for Development Policy. The present paper, which refers to this index, first examines how a structural economic vulnerability index can be designed for the low-income...

– A Conceptual Framework with Reference to Widows
This paper analyses the transmission channels through which mass violent conflict and post-conflict fragility affect households. It does so by pointing out how a fragile environment impairs a household’s core functions, boundaries, and its choice of income generating activities. Furthermore, it...
Working Paper
pdf
There are alternative definitions of vulnerability to poverty. Most researchers prefer to define vulnerability as the probability of a household or individual falling into poverty in the future. Based on this definition and using household survey panel data from rural China, this paper attempt to...

– Exploring the Linkages between Poverty, Gender, and Disaster Vulnerability in Caribbean SIDS
This paper explores the linkages between poverty and disaster vulnerability in the context of remittance flows to households in the Caribbean. Jamaica is used as the case study country. The paper discusses the channels through which natural disasters and remittances affect each other but also...
Working Paper

– Concepts and Measurements
In this paper, economic vulnerability is defined as the exposure of an economy to exogenous shocks, arising out of economic openness, while economic resilience is defined as the policy-induced ability of an economy to withstand or recover from the effects of such shocks. The paper briefly reviews...
Working Paper
pdf
A small but growing literature has been concerned about the economic (and environmental) vulnerability on the level of countries. Less attention is paid to the economic vulnerability of different regions within countries. By focusing on the vulnerability of subnational regions, our paper contributes...

– The Case of China’s Rural Poor
This paper investigates the economic conditions of rural households in China. Historical survey data indicate that over 80 per cent of rural households earn less than 4,500 yuan in net disposable income each year, that for the vast majority of rural households disposable income is insufficient to...

– Case Study of the 2004 Indian Ocean Tsunami in Sri Lanka and Indonesia
Current approaches of measuring vulnerability to natural hazards generally use a rather static perspective that focuses on a single point in time—often before a hazardous event occurs. In contrast, the paper argues that vulnerability assessment should also take into account the changing dynamics...
