Measurement error in recall surveys and the relationship between household size and food demand.

-0.061 -0.065 [H.sub.0]: [[sigma]. F = 8.77 ** F =12.70 ** sub.Round1] = [[sigma]. sub.Round2] Note: Standard error estimates and hypothesis tests correct for cluster structure of the samples. Standard errors in (): ** = significant at 1% level. * = significant at 5% level. The degrees of freedom for the F-tests are 1 and 590. All regressions contain the logarithm of per capita total expenditure, the logarithm of household size, the ratios to household size of the number of males and females in the 0-4, -5--9, 10-14, 15-29. 30-54, and (males only) 55+ age groups, the fraction of adults whose main occupation is agricultural self-employment, agricultural employment and non-agricultural work, a dummy variable for farm households, and dummy variables for region and sector. (a) The log of per capita income (excluding in-kind items that are used in the calculation of both income and consumption) is used as the instrument. The partial [R.sup.2] for the instrument in the first stage regression is 0.329 and the F-test for excluding the instrument is 2,923.
