Summary This paper uses household and village-level survey data to investigate the food security of male- and female-headed households in Bangladesh with particular attention to indigenous ethnic groups, and finds no significant differences in the food security between these two types of...

This paper, using data from a quasi-random control experiment on BRAC’s “Targeting the Ultra Poor” program in Bangladesh, investigates whether a one-off large grant to the extreme poor enables them to participate in the regular microfinance program that typically excludes them. The extreme...

Although the importance of the elasticity of substitution between capital and labor (σ) has long been recognized in several branches of economics, it has received too little attention in the growth literature. This paper aims to partly rectify this omission by exploring the growth potentials...

The elasticity of substitution between capital and labor (σ) is a second-order parameter of the production function but has a first-order effect on economic growth. Although the importance of this elasticity has long been recognized in several branches of economics, it has received too little...

In discrete choice models the marginal effect of a variable of interest that is interacted with another variable differs from the marginal effect of a variable that is not interacted with any variable. The magnitude of the interaction effect is also not equal to the marginal effect of the...

This paper uses household and village level survey data to investigate the food security of male and female headed households in Bangladesh with particular attention to indigenous ethnic groups. Given the broadness of the concept of food security and complexities of choosing any particular...

Large and sustained differences in marginal products of capital (MPKs) across countries are sharply at odds with the core implications of the neoclassical framework. Lucas (1990) and many subsequent studies have examined reasons for this MPK differential. In a recent contribution, Caselli and...

This note uses insights from cointegration analysis to reexamine two separate but related issues concerning the estimation of production function parameters. Fisher (1971) documented a paradox in estimating substitution elasticities -- the puzzling divorce between the technology underlying his...

In discrete choice models the marginal effect of a variable of interest that is interacted with another variable differs from the marginal effect of a variable that is not interacted with any variable. The magnitude of the interaction effect is also not equal to the marginal effect of the...

This paper investigates whether a big push to the extreme poor in terms of a one-off large grant enables them to participate in the microfinance program. The analysis uses data from a quasi-experiment on BRAC’s ultra poor program in Bangladesh. The results for the baseline and repeat survey...
