Where to Put the Kids? Effects of Type of Non-parental Child Care on Pre-teen Skills and Risky Behavior This paper investigates pre-teenage effects of the choice of type of non-parental child care at age three (preschool relative to more informal family day care). We exploit a Danish panel data child survey merged with administrative records along with a pseudo-experiment that generates variati...

This paper provides a summary of the findings contained in a forthcoming issue of the Latin American Journal of Economics on entrepreneurship in Latin America as a vehicle for upward social mobility, especially for the middle class. The income persistence coefficients estimated with pseudo-panel data for Colombia, Ecuador, and Uruguay indicate that entrepreneurial activity is a channel of inter...

A rich class of parametric models is proposed for discrete choice data based on the scale mixture of multivariate normal distributions. The multinomial probit model is a special case in the class. The new models can be implemented in a Bayesian framework without much difficulty because of their special connections to the multinomial probit model. A Gibbs sampler with data augmentation is used t...

We study the properties and relations of fuzzy pseudo-filters of pseudo-BCK algebras. After we discuss the equivalent conditions of fuzzy normal pseudo-filter of pseudo-BCK algebra (pP), we propose fuzzy implicative pseudo-filter and its relation with fuzzy Boolean filter of (bounded) pseudo-BCK algebras (pP). Then two open problems: “In pseudo-BCK algebra or bounded pseudo-BCK algebra, Is the ...

Pseudo equality algebras were initially introduced by Jenei and Kóródi as a possible algebraic semantic for fuzzy type theory, and they have been revised by Dvurečenskij and Zahiri under the name of JK-algebras. In this paper we define and study the commutative pseudo equality algebras. We give a characterization of commutative pseudo equality algebras and we prove that an invariant pseudo equa...

Pseudo-MTL algebras or weak pseudo-BL algebras are non-commutative fuzzy structures which arise from pseudo-t-norms, namely, pseudo-BL algebras without the pseudo-divisibility condition. The aim of this paper is to investigate the properties of pseudo-BL algebras that also hold for pseudoMTL algebras. We will also study some classes of pseudo-MTL algebras such as good, local and Archimedean pse...

A previously healthy 23-year-old Japanese male had complained of a fever lasting a month. A physical examination revealed marked hepatosplenomegaly without significant peripheral lymphadenopathies. Routine laboratory tests showed a hemoglobin level of 9.1 g/dL, 95 3 10/L platelets, 7.1 3 10/L leukocytes, and an elevated lactate dehydrogenase level of 522 U/L (reference interval, 120-220 U/L). A...

Since 1987 the Social Security Administration (SSA) has published a special set of tabulations on SSA program recipients in the Annual Statistical Supplement to the Social Security Bulletin using data derived from the Census Bureau's Survey of Income and Program Participation (SIPP). Estimates of sampling errors pertaining to these tabulations were derived from the 1984 SIPP panel. This article...

The paper analyses the variability of labour incomes in Argentina from mid-eighties to 2005. The magnitude of the income-instability phenomenon is estimated and its determinants are evaluated under different macroeconomic contexts. The document also analyses how income fluctuations have affected the inequality of income distribution. Finally, the income convergence hypothesis is explored. Data ...
