Rent-seeking with non-identical sharing rules

The primary object of this paper is to examine the role of differential sharing rules within a collective rent-seeking setting on the possible non-existence of Nash equilibrium. Focusing on groups that distribute part of the rent equally among their members and the residual according to relative effort, we show that in rent-seeking societies applying the two polar sharing rules equilibrium never exists. In the general case where groups apply different but not necessarily the polar sharing rules, we study the relationship between group variability in distributing rents and the problem of non-existence of equilibrium in the rent-seeking game.     

Rent-seeking for pure public goods

In this paper we present a formal analysis of rent-seeking for public goods by two or more groups with different numbers of individuals. We begin by considering equally wealthy groups under risk neutrality, a case which constitutes our basic model. Several surprising and interesting results emerge from the analysis of this basic case. The problem is then extended to deal with (a) groups with different wealth levels, and (b) risk aversion. This last extension brings about a further crop of interesting and useful results.     

Realizing the Promise of Well‐Being: Longitudinal Research from an Effective Early Intervention Program for Substance Exposed Babies and Toddlers Identifies Essential Components

The University of Miami Linda Ray Intervention Program (LRIP) is a Part C early intervention program for children under the age of three, with verified developmental delays located in Miami‐Dade County that has established a strong link and referral process from the Juvenile Court as well as local community‐based care agencies. Creating a system where early intervention communicates well with the court system is paramount in changing the well‐being trajectories of these vulnerable children. This article describes the growing need for early intervention services as well as the results of one successful early intervention‐court partnership that has shown promising short and long‐term results for developmentally‐delayed children who were born prenatally exposed to cocaine.     

Monopoly vs. competition in light of extraction norms

This note demonstrates that whether the market is competitive or monopolistic need not be the result of ideology, political power or non-convexity of the technology. The answer can be determined by a government that maximizes the extracted resources from the alternative market structures. Our claim is illustrated by assuming that demand and supply are linear functions and that the government can extract the same share of the producers?? profit under the alternative market structures. This share can be extracted from the actual producers or from the potential producers who take part in the contest to get a license to produce.

Adolescent perception of family climate and adaptation to residential schooling

The article investigates the role that adolescents' perceptions of the family plays as he/she adapts to living away from home. Family atmosphere perceptions of adolescents who study at a residential school and adolescents who live at home were evaluated. The adaption of these two groups of adolescents, as perceived by their teachers, was also evaluated. Results have shown differential contributions of family dimensions to adolescent adaptation in residential and nonresidential schooling. Results are discussed in connection with the process of adolescent separation from the family and the increased impact of the peer group.In 1987–1988, Visiting Faculty, Institute of Child Development, University of Minnesota.
