We use data from eight different consumption questionnaires randomly assigned to 4,000 households in Tanzania to obtain evidence on the nature of measurement errors in estimates of household consumption. While there are no validation data, the design of one questionnaire and the resources put...

The paper analyzes one case of the endogeneity problem, namely, the presence of measurement error in consumer expenditures by estimation of the demand system according to the household sample surveys. Based on factor analysis a novel approach is proposed and tested. It allows weakening the bias...

Since the late 90s, regression discontinuity designs have been widely used to estimate local treatment effects. When the running variable is observed with continuous errors, identification fails even if the dispersion of measurement errors is small. Assuming non-differential measurement errors,...

This paper proposes a new method of obtaining identification in mismeasured regressor models, triangular systems, and simultaneous equation systems. The method may be used in applications where other sources of identification such as instrumental variables or repeated measurements are not...

In response to the Deaton and Dreze (2009) explanation of a downward shift in the calorie Engel curve in terms of lower requirements due to health improvements and lower activity levels in India, we develop an alternative explanation embedded in a standard demand theory framework, with food...

This chapter focuses on the Indian experience with dietary changes, their nutritional implications, and policy response to alleviate nutritional deprivation. We review the evidence on nutrient intake and dietary changes, particularly the downward shift in calorie, protein and other nutrient...

Building on a recent important contribution by Deaton and Dreze (2009), our analysis sheds new light on why the calorie Engel curve shifted down-especially in rural India- over the period 1993–2004. The puzzle for the longer period analysed by Deaton and Dreze (2009) is that despite higher...

In response to the Deaton–Dreze (2009) explanation of a downward shift in the calorie Engel curve in terms of lower requirements due to health improvements and lower activity levels, we have developed an alternative explanation of changes in the consumption of calories, protein and fats over...

We propose a generalization of random coefficients models, in which the regression model is an unknown function of a vector of regressors, each of which is multiplied by an unobserved error. We also investigate a more restrictive model which is additive (or additive with interactions) in unknown...
