This paper studies disinflationary shocks in a non-linear New Keynesian model with search and matching frictions and moral hazard in the labor markets. Our focus is on understanding the wage formation process as well as welfare costs of disinflations in the presence of such labor market frictions. The presence of imperfect information in labor markets imposes a lower bound on worker surplus tha...

Union membership displayed a n-shaped pattern over the 20th century, while the distribution of income sketched a u. A model of unions is developed to analyze these phenomena. There is a distribution of firms in the economy. Firms hire capital, plus skilled and unskilled labor. Unionization is a costly process. A union decides how many firms to organize and its members wage rate. Simulation of t...

There is a distribution of firms in the economy. Firms hire capital, plus skilled and unskilled labor. Unionization is a costly process.

Spontaneous preterm labor is a complex process characterized by the interplay of multiple different pathways. Prevention of preterm labor and delivery is also complicated. The most effective interventions for prevention of preterm birth (PTB) are progestin prophylaxis and lifestyle modifications, with cerclage placement also playing a role in selected populations. Interventions such as activity...

In the present paper, we adopt the usual assumptions of the collective approach, i.e., individualism and efficiency, to study household labor supply. The theoretical innovation is twofold. Firstly, we incorporate in the initial setting the decision to participate to the labor market. Secondly, we abandon the assumption of linearity of the budget constraint. We show that (i) structural elements ...

The last few hours of human pregnancy are characterized by uterine contractions that effect dilatation of the cervix and force the fetus through the birth canal. The myometrial contractions of labor are painful, which is why the term labor pains is used to describe this process. Before these forceful, painful contractions begin, however, the uterus must be prepared for labor. During the first 3...

Two major themes pervade the outstanding contributions of W H. Hutt. The first is his attempt to clarify and advance our understanding of the coordination process of the market, especially the market for labor, and the second is his career-long critique of the Keynesian theoretical framework. It becomes quickly obvious from reading almost any of his books, and many of his articles, that those t...

Fetal membranes usually rupture during the process of labor. Premature fetal membrane rupture occurs not infrequently and is associated with significant fetal and maternal morbidity. The mechanisms of normal and pathologic fetal membrane rupture are not well understood. We have examined structural and biochemical changes in the rat amnion as labor approaches in order to characterize this proces...
