Modern society depends on software systems of ever-increasing scope and complexity in virtually every sphere of human activity, including business, finance, energy, transportation, education, communication, government, and defense. Because the consequences of failure can be severe, dependable...

The paper explores the role social network capital might play in facilitating poor agents’ escape from poverty traps. We model endogenous network formation among households heterogeneously endowed with both traditional and social network capital who make investment and technology choices over...

Many governments try to stabilize commodity prices based on the widespread belief that households value price stability and that the poor especially benefit from food price stabilization. We derive an exact measure of multivariate price risk aversion and of associated household willingness to...

Supermarkets, specialized wholesalers, and processors and agro-exporters’ agricultural value chains have begun to transform the marketing channels into which smallholder farmers sell produce in low-income economies. We develop a conceptual framework through which to study contracting between...

Empirical studies across many developing countries routinely document a positive correlation between participation in rural nonfarm employment and households’ wealth or income. This paper explores whether nonfarm employment leads to higher consumption expenditure growth in Ethiopia. We find...

We study rural employment transitions in Ethiopia between farming and both low- and high-return nonfarm employment. We find that initial asset holdings and access to saving and credit are important factors for transition into high-return rural nonfarm employment and that households’...

This paper examines the nonfarm employment choice of individuals using panel data from Ethiopia that covers the period 1994-2004. Non-farm activities that require more resources in the form of skill or capital yield higher returns but employ proportionately fewer people. Women have lower...

Index insurance products circumvent many of the transaction costs and asymmetric information problems that obstruct provision of low value conventional insurance policies in developing countries. Recent years have seen tremendous growth in index insurance pilots in developing countries, but...

Cash transfers and index insurance have become popular interventions by development agencies worldwide. But they operate in radically different ways. In principle, these could offer complementary or substitute means of improving households’ well-being, both through direct payments and through...

The paper explores the role social network capital might play in facilitating poor agents’ escape from poverty traps. We model and simulate endogenous network formation among households heterogeneously endowed with both traditional and social network capital who make investment and technology...
