This paper first reviews some of the approaches that have been taken to estimate the common parameters of binary outcome models with fixed effects. We limit attention to situations in which the researcher has access to a data set with a large number of units (individuals or firms, for example)...

One-quarter of married, fertile-age women in Sub-Saharan Africa report not wanting a pregnancy and yet do not use contraceptives. To study this issue, we collect detailed data on women’s subjective probabilistic beliefs and estimate a structural model of contraceptive choices. Our results...

Nearly one-quarter of married, fertile-age women in Sub-Saharan Africa say that they want to avoid pregnancy but are not using contraceptives. To the best of our knowledge, this paper is the first to study this puzzle in a developing country using detailed data on women's subjective...

Hoarding of staples has long worried policymakers due to concerns about shortages. We quantify how sticky store prices---delayed price adjustment to shocks by reputable retailers---exacerbate hoarding. When prices are sticky, households hoard not only for precautionary motives but also...

We study consumer spending dynamics during the first infection wave of the COVID-19 pandemic using household scanner data covering fast-moving consumer goods in the United Kingdom. We document a large spike in spending for storable products, such as food staples and household supplies, in the...

This paper introduces measures for how each moment contributes to the precision of the parameter estimates in GMM settings. For example, one of the measures asks what would happen to the variance of the parameter estimates if a particular moment was dropped from the estimation. The measures are...
