Standardized enforcement: Access to justice vs contractual innovation

We model the different ways in which precedents and contract standardization shapethe development of markets and the law. In a setup where more resourceful parties candistort contract enforcement to their advantage, we find that the introduction of astandard contract reduces enforcement distortions relative to precedents, exerting twoeffects: i) it statically expands the volume of trade, but ii) it crowds out the use ofinnovative contracts, hindering contractual innovation. We shed light on the largescale commercial codification occurred in the 19th century in many countries (evenCommon Law ones) during a period of booming commerce and long distance trade.

Status of Young Women in the Juvenile Justice System Preliminary Data, 2007

Young women involved in the juvenile justice system present with characteristics and experiences that differentiate them from their male counterparts. As such, the juvenile justice system in Iowa must consider these factors if it is to effectively and efficiently impact recidivism and rehabilitation.

Negativity effect and the emergence of ideologies

``Negativity effect'' refers to the psychological phenomenon that peopletend to attach greater weight to negative information than to equallyextreme and equally likely positive information in a variety of informationprocessing tasks. Numerous studies of impression formation have found thatnegative information is weighted more heavily than positive information asimpressions of others are formed. There is empirical evidence in politicalscience that shows the importance of the negativity effect in the informationprocessing of the voters. This effect can explain the observed decreaseof popularity for a president the longer he is in office. \\We construct a dynamic model of political competition, incorporating thenegativity effect in the decision rule of the voters and allowing their preferencesto change over time, according to the past performance of the candidateswhile in office. Our model may explain the emergence of ideologies out ofthe competition for votes of myopic candidates freely choosing policypositions. This result gives rise to the formation of political parties,as infinitely--lived agents with a certain ideology. Furthermore, in thismodel some voters may start out by switching among parties associated withdifferent policies, but find themselves supporting one of the parties fromsome point on. Thus, the model describes a process by which some votersbecome identified with a ``right'' or ``left'' bloc, while others ``swing''between the two parties.

Organização Criminosa e Actividade Criminal: Implicações da Estruturação do Gangue

A investigação acerca dos gangues, da sua organização e da sua influência no comportamento dos seus membros tem vindo a aumentar ao longo dos últimos anos. Contudo, a maioria dos estudos centra-se nos factores que levaram os indivíduos a integrarem um gangue, limitando assim a nossa compreensão acerca desta matéria. Com esta finalidade, foram realizadas entrevistas semi-estruturadas a 47 elementos de gangues, abordando não só as suas histórias de vida, mas também a relação entre a estrutura e organização do gangue e variáveis comportamentais como o envolvimento em crimes violentos, venda de drogas, vitimização e auto-controle. Os resultados demonstram a existência de diferenças claras entre membros de gangues organizados e membros de gangues desorganizados, no que concerne aos seus crimes cometidos, a venda de drogas, e à vitimização a que estão sujeitos. Verifica-se ainda que membros de gangues organizados procuram mais o risco e evidenciam menos respeito pelas outras pessoas. Em suma, mesmo baixos níveis de organização do gangue são relevantes para o comportamento dos indivíduos que os integram, sendo que uma maior organização do gangue está relacionada com um aumento significativo de ofensas e de vitimização.

Status of Females in the Juvenile Justice System, 2007

On October 12th 2007, the inaugural Girls’ Summit on females in the juvenile justice system was held. This Summit brought together key decision makers in an exploration of research and data. Those who attended were also asked to make recommendations regarding a course of action. This report represents an effort to improve our response to these young women in Iowa. It highlights pertinent information covered at the Summit as well as resulting conclusions and recommendations. On behalf of the Iowa Gender Specific Services Task Force and the participants of the Girls’ Summit, it is my hope that this report will serve as a road map for necessary improvements as well as a means to reinforce the effective tools that are already in place. There are differences that exist between young women and young men in the juvenile justice system and the efficacy of professionals rests heavily on a better understanding of these differences and how they impact the justice system response.

Corporate criminal law and organization incentives: A managerial perspective

Corporate criminal liability puts a serious challenge to the economictheory of enforcement. Are corporate crimes different from other crimes?Are these crimes best deterred by punishing individuals, punishing corporations, or both? What is optimal structure of sanctions? Shouldcorporate liability be criminal or civil? This paper has two majorcontributions to the literature. First, it provides a common analyticalframework to most results presented and largely discussed in the field.In second place, by making use of the framework, we provide new insightsinto how corporations should be punished for the offenses committed bytheir employees.

Optimal law enforcement and criminal organization

In this paper, we take an organizational view of organized crime. In particular, we study the organizational consequences of product illegality attending at the following characteristics: (i) contracts are not enforceable in court, (ii) all participants are subject to the risk of being punished, (iii) employees present a major threat to the entrepreneur having the most detailed knowledge concerning participation, (iv) separation between ownership and management is difficult because record-keeping and auditing augments criminal evidence.

On the justice of voting systems

What are the best voting systems in terms of utilitarianism? Or in terms of maximin, or maximax? We study these questions for the case of three alternatives and a class of structurally equivalent voting rules. We show that plurality, arguably the most widely used voting system, performs very poorly in terms of remarkable ideals of justice, such as utilitarianism or maximin, and yet is optimal in terms of maximax. Utilitarianism is bestapproached by a voting system converging to the Borda count, while the best way to achieve maximin is by means of a voting system converging to negative voting. We study the robustness of our results across different social cultures, measures of performance, and population sizes.

Intergenerational justice when future worlds are uncertain

Let there be a positive (exogenous) probability that, at each date, the human species will disappear.We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under thisuncertainty, with expected-utility preferences. Various social welfare criteria entail alternativevon Neumann- Morgenstern utility functions for the EO: utilitarian, Rawlsian, and an extensionof the latter that corrects for the size of population. Our analysis covers, first, a cake-eating economy(without production), where the utilitarian and Rawlsian recommend the same allocation.Second, a productive economy with education and capital, where it turns out that the recommendationsof the two EOs are in general different. But when the utilitarian program diverges, thenwe prove it is optimal for the extended Rawlsian to ignore the uncertainty concerning the possibledisappearance of the human species in the future. We conclude by discussing the implicationsfor intergenerational welfare maximization in the presence of global warming.
