In this paper we study maximum likelihood estimation (MLE) of the roughness parameter of the distribution for speckled imagery (Frery et al., 1997). We discover that when a certain criterion is satisfied by the sample moments, the likelihood function is monotone and MLE estimates are...

We study participation and relative earnings in the formal, informal, and self-employed sectors in Bolivia. We estimate quantile earnings equations corrected for self-selectivity to address potential biases in the estimates of relative earnings gaps due to the endogeneity of sector...

This text argues that the criteria used to define Bolsa Família benefits and the criteria used to establish coverage targets are inconsistent. While individual concession criteria are that beneficiaries should be paid for two years if they do not suffer large upward income mobility, the...
