Recent changes in Public Administration brought local government management to a new era. In recent years we witnessed a huge transformation in this reality. Early forms of organization, control and coordination of public goods have been replaced by other forms of organization such as contracting-out, private/public partnerships and public enterprises and agencies. Using a transactions cost framework, along with financial situation analysis, environmental complexity and political degree of stability we seek to find relevant factors that drive local government choices regarding the coordination mechanisms in the provision of public services.

A questão central dessa tese é entender as razões e a natureza das falhas de coordenação em sistemas agroindustriais complexos. A temática de falhas de coordenação é um problema multifacetado e complexo, representando um desafio para pesquisadores. Uma observação crítica das organizações leva à conclusão de que as falhas organizacionais, faceta visível das falhas de coordenação, são a regularidade no mundo organizacional. Essa constatação instiga e justifica esta pesquisa, sendo seu objeto de estudo a transação entre o produtor rural e a indústria frigorífica no Sistema Agroindustrial (SAG) da carne bovina. Especificamente, buscou-se estudar a razão e a natureza das falhas organizacionais a partir de diferentes aportes teóricos, com foco nas falhas de natureza institucional e informacional. Analisou-se o papel das instituições formais e informais para a resolução dos conflitos no SAG da carne bovina e as falhas na transmissão de incentivos ao longo de subsistemas de qualidade. Com base no suporte teórico oferecido pela Nova Economia Institucional, especialmente a Economia dos Custos de Transação, a Teoria do Agente-Principal e a Teoria dos Custos de Mensuração, desenvolveu-se três ensaios: dois ensaios empíricos e um ensaio teórico. O ensaio teórico explorou os determinantes da cooperação e das falhas de coordenação sob diferentes lentes e discutiu-se a necessidade de uma Teoria das Falhas. Um constructo analítico foi proposto e as dimensões de ordem institucional e informacional foram posteriormente exploradas nos ensaios empíricos. No primeiro ensaio empírico...

Os investimentos em Pesquisa e Desenvolvimento têm se constituído como fonte importante de vantagem competitiva, especialmente com o aprofundamento das decorrências da globalização dos mercados. A soma dos investimentos em P&D que os 27 países-membros da Comunidade Européia fizeram em 2007 superou EUR227 bilhões, ao passo que no mesmo ano os EUA investiram US$368 bilhões em P&D. Dados da OCDE e UNESCO apontam para um aumento do investimento global em P&D de US$525 bilhões em 1996 para mais de US$1 trilhão em 2006. Tendo em vista o cenário de franca expansão das funções de Pesquisa e Desenvolvimento e do já consolidado movimento de descentralização do P&D em direção às subsidiárias da empresa multinacional, emerge a necessidade de coordenação global de esforços e uso racional dos recursos, de modo a tornar os investimentos e a gestão de P&D mais eficazes. A eficácia à qual se refere está na base da competitividade, na medida em que pode facilitar a flexibilidade da organização para fazer frente à dinâmica do mercado, auxiliar na economia de recursos e maximizar o retorno sobre os investimentos em infraestrutura e capacitação da mão-de-obra. Essa pesquisa se debruça sobre a questão da coordenação dos esforços de P&D em uma empresa multinacional de base tecnológica que tem centros de P&D em diversos países. São tratados temas relativos aos mecanismos de coordenação...

Entidades humanitárias, organizações privadas e governos atuam constantemente no atendimento a vítimas de desastres que aumentam continuamente e atingem milhares de pessoas todos os anos. O objetivo da presente pesquisa é analisar os mecanismos de coordenação e as formas de colaboração na cadeia de suprimentos humanitária. Para tanto, foi realizado o levantamento e análise do referencial teórico para se permitir a caracterização dos cenários de desastres; a identificação e compreensão dos desafios de gerenciamento da cadeia de suprimentos humanitária; a identificação dos indicadores de desempenho inerentes à gestão desta cadeia específica; os mecanismos de colaboração existentes e utilizados; e a importância de simuladores organizacionais para análise da tomada de decisão e dos jogos de empresa para vivências. A partir da análise do referencial teórico, foi desenvolvido um esquema conceitual simplificado dos mecanismos de coordenação descentralizado e centralizado, incluindo a análise dos stakeholders envolvidos (agentes humanitários locais, agentes humanitários coordenadores, beneficiários e prestadores de serviço de armazenagem, transporte e aquisição), das decisões tomadas por cada um, das etapas logísticas e dos indicadores importantes para garantir o atendimento dos beneficiários. A partir do desenvolvimento do esquema conceitual simplificado dos mecanismos de coordenação...

Este trabalho aborda o problema da coordenação de atividades interdependentes em processos computacionais. As interdependências entre atividades podem ser temporais, de recursos, de bloqueio e de mútua exclusão, entre outras. Exemplos de processos computacionais com atividades interdependentes são ambientes multimídias, ferramentas de suporte ao trabalho colaborativo, workflows, vídeo games, animação computacional e composição de web services. Uma das dificuldades em projetar o mecanismo de coordenação é garantir que tal mecanismo seja consistente com a especificação do processo. Vários trabalhos sugerem o uso de ferramentas de modelagem como redes de Petri ou linguagens de coordenação para construir um mecanismo de coordenação. Um desse trabalhos apresenta a metodologia Grafo de Relações (GR) que trata das dependências temporais entre atividades. Esta dissertação apresenta uma extensão da metodologia GR para lidar com dependências de recursos, uma ferramenta para automatizar a modelagem do mecanismo de coordenação e uma proposta para o coordenador (componente de software responsável pela coordenação das atividades); This work approaches the problem of coordination of activities in computational processes. The coordination necessity appears when there are interdependencies among activities. The type of interdependencies can be temporal...

This research is based on the premises that teams can be designed to optimize its performance, and appropriate team coordination is a significant factor to team outcome performance. Contingency theory argues that the effectiveness of a team depends on the right fit of the team design factors to the particular job at hand. Therefore, organizations need computational tools capable of predict the performance of different configurations of teams. ^ This research created an agent-based model of teams called the Team Coordination Model (TCM). The TCM estimates the coordination load and performance of a team, based on its composition, coordination mechanisms, and job’s structural characteristics. The TCM can be used to determine the team’s design characteristics that most likely lead the team to achieve optimal performance. ^ The TCM is implemented as an agent-based discrete-event simulation application built using JAVA and Cybele Pro agent architecture. The model implements the effect of individual team design factors on team processes, but the resulting performance emerges from the behavior of the agents. These team member agents use decision making, and explicit and implicit mechanisms to coordinate the job. The model validation included the comparison of the TCM’s results with statistics from a real team and with the results predicted by the team performance literature. An illustrative 26-1 fractional factorial experimental design demonstrates the application of the simulation model to the design of a team. The results from the ANOVA analysis have been used to recommend the combination of levels of the experimental factors that optimize the completion time for a team that runs sailboats races. ^ This research main contribution to the team modeling literature is a model capable of simulating teams working on complex job environments. The TCM implements a stochastic job structure model capable of capturing some of the complexity not capture by current models. In a stochastic job structure...

The complexity of business markets, resulting from different levels of organization and the ways social constructs combine across levels, means no clear theory of relational coordination has been developed. The relationship and network framework of the industrial marketing and purchasing (IMP) group provides a means of handling this complexity. This paper proposes a collaborative interest model (CIM) of relational coordination, which partially overcomes these problems by examining the coordination process within a context that accounts for levels of organization. This conceptualization of coordination processes resulting from firm intentions to achieve relationship performance presents a new way to empirically examine relational coordination. An empirical test of the model using structural equation methodology shows relational coordination (i.e., commitment and trust) explains relationship performance better than market coordination mechanisms; Christopher J.

Organizational research shows how mismatches between organizational design characteristics and contingency factors lead to lower performance. In addition to classic contingency factors, knowledge is a powerful resource that influences performance. This research explores knowledge as a structural contingency factor for interorganizational systems. It explores the performance effects of different types of knowledge (i.e., tacit and explicit) interacting with organizational coordination mechanisms (e.g., direct supervision and mutual adjustment) in the highly complex environment of crisis events (e.g., natural disasters) where multiple organizations often rapidly develop reciprocal interdependencies. In those events, teams of boundary spanners often work to coordinate the interorganizational response; hence, understanding how performance is affected by the interaction of knowledge types available and various coordination mechanisms is useful to managers. Using a mixed methodology design, this research extends structural contingency theory to the interorganizational level. First, immersive qualitative field research is conducted to observe widely dispersed organizations during a developing crisis. Those observations help formulate a baseline agent-based computational organizational model. Using that baseline...

In this paper, multi-stage auction-based intelligence, surveillance, and reconnaissance (ISR) coordination mechanisms are investigated in the context of dynamic and uncertain mission environments, such as those faced by expeditionary strike groups. Each atribute of the mission task is modeled using a hidden Markov model (HMM) with controllable emission matrices, corresponding to eash ISR asset. For each HMM-sensor pair, we evaluate a metrix of information gains (uncertainty reduction measures); the elements of this matrix depend on the coordination structure and the concomitant delays accrued. We consider three coordination structures (distributed ISR coordination, ISR officer serving as a coordinator, ISR officer serving as a commander) here. We evaluate these structures on a hypothetical mission scenario that requires the monitoring of ISR activities in multiple geographic regions. The three structures are evaluated by comparing the task state estimation error cost, as well as travel, waiting and assignment delays. The results of analysis were used as a guide in the design of a mission scenario and asset composition for team-in-the-loop experimentation at NPS. Our solution has the potential to be a mixed initiative decision support tool to an ISR coordinator/commander...

The Uruguay Non-lending Technical Assistance (UY NLTA) for Uruguay was undertaken at the request of the Government of Uruguay's Ministry of Social Development (MIDES). Following a devastating financial and macroeconomic crisis in 2002, MIDES was established with a view to coordinating social programs and providing a safety net program for Uruguayans affected by the crisis: the National Assistance Plan of Social Emergency (PANES), which was established in 2005. The objectives of the UY NLTA are to: (i) evaluate the impact of PANES social emergency programs; (ii) inform a dialogue about the future role of social emergency programs and of MIDES as the lead authority responsible for the coordination and oversight of social policy in Uruguay, and (iii) strengthen MIDES capacity to assess, monitor and evaluate social policy in Uruguay, with considerable weight on participatory approaches to monitoring and evaluation.

L’agenda de la coordination apparu au tournant des années 2000 repose sur l’idée que plus les actions des donneurs sont harmonisées et transparentes, plus grande est l’efficacité de l’action collective. C’est du moins l’esprit porté par les différentes déclarations sur l’efficacité de l’aide (Accra en 2008, Paris en 2005, Rome en 2003) qui ont mis en avant la coordination. C’est pourquoi, depuis une décennie nous assistons à l’élaboration de dispositifs communs « optimaux » de coordination (mécanismes de coordination) qui peuvent aller des plans d’action stratégique des partenariats public-privés (PPP) aux documents de stratégies de réduction de la pauvreté en passant par l’aide programme. Partant du secteur de la santé, nous essayons de montrer dans cet article que les images politiques, combinées au caractère contractuel de ces mécanismes de coordination, font qu’ils remplissent difficilement les conditions d’une coordination efficace.

Cette recherche s'intéresse à l'acteur patronal organisé, encore peu étudié en Amérique du Nord. Pourtant, cet acteur est fortement organisé au Québec et il exerce une influence reconnue sur les politiques publiques et les relations industrielles. Cette recherche vise à mieux comprendre la logique d’action des employeurs et les lieux où ils exercent leur influence. Plus important encore, la recherche s’interroge sur les mécanismes de diffusion utilisés par les associations patronales pour transmettre à leurs membres des orientations et des lignes directrices à adopter. Tout comme pour l’acteur syndical qui doit développer sa capacité représentative (Dufour, Hege, Levesque et Murray, 2009), nous croyons qu’il en est de même pour l’acteur patronal. Bref, cette étude cherche à comprendre comment les associations patronales vont s'assurer que leurs membres adoptent des pratiques en lien avec les positions défendues dans les institutions du marché du travail et dans la sphère des politiques publiques. Notre question de recherche est la suivante : Quels sont les mécanismes développés par les associations patronales pour diffuser leurs orientations en matière de politiques publiques et de relations du travail en vue d’influencer les pratiques locales de gestion de leurs membres?

This paper investigates the relationship between [MNC] coordination mechanisms and subsidiary new product development [NPD] activities. We focus on two essentially different coordination mechanisms, internal markets and global decision-making autonomy, and argue that both mechanisms are likely to increase a subsidiary's exposure to market forces which, in turn, provides different kinds of incentives for a subsidiary's in-house NPD and NPD outsourcing. We tested our hypotheses using structural equations modeling. The results suggest that internal markets have a positive effect on NPD outsourcing while global autonomy has a positive effect on inhouse NPD. Thus, this study contributes to integrating the internal market construct with the coordination mechanism stream of literature.

We study policies aiming to minimize the weighted sum of completion times of jobs in the context of coordination mechanisms for selfish scheduling problems. Our goal is to design local policies that achieve a good price of anarchy in the resulting equilibria for unrelated machine scheduling. To obtain the approximation bounds, we introduce a new technique that while conceptually simple, seems to be quite powerful. With this method we are able to prove the following results. First, we consider Smith's Rule, which orders the jobs on a machine in ascending processing time to weight ratio, and show that it achieves an approximation ratio of 4. We also demonstrate that this is the best possible for deterministic non-preemptive strongly local policies. Since Smith's Rule is always optimal for a given assignment, this may seem unsurprising, but we then show that better approximation ratios can be obtained if either preemption or randomization is allowed. We prove that ProportionalSharing, a preemptive strongly local policy, achieves an approximation ratio of 2.618 for the weighted sum of completion times, and an approximation ratio of 2.5 in the unweighted case. Again, we observe that these bounds are tight. Next, we consider Rand, a natural non-preemptive but randomized policy. We show that it achieves an approximation ratio of at most 2.13; moreover...

We present new coordination mechanisms for scheduling selfish jobs on $m$ unrelated machines. A coordination mechanism aims to mitigate the impact of selfishness of jobs on the efficiency of schedules by defining a local scheduling policy on each machine. The scheduling policies induce a game among the jobs and each job prefers to be scheduled on a machine so that its completion time is minimum given the assignments of the other jobs. We consider the maximum completion time among all jobs as the measure of the efficiency of schedules. The approximation ratio of a coordination mechanism quantifies the efficiency of pure Nash equilibria (price of anarchy) of the induced game. Our mechanisms are deterministic, local, and preemptive. Our first coordination mechanism has approximation ratio $\Theta(\log m)$ and guarantees that the induced game has pure Nash equilibria. This result improves a bound of $O(\log^2 m)$ due to Azar, Jain, and Mirrokni and uses a global ordering of the jobs according to their distinct IDs. Our second mechanism handles anonymous jobs and has approximation ratio $O(\frac{\log m}{\log \log m})$ although the game induced is not a potential game and, hence, the existence of pure Nash equilibria is not guaranteed by potential function arguments. However...

We reconsider the well-studied Selfish Routing game with affine latency functions. The Price of Anarchy for this class of games takes maximum value 4/3; this maximum is attained already for a simple network of two parallel links, known as Pigou's network. We improve upon the value 4/3 by means of Coordination Mechanisms. We increase the latency functions of the edges in the network, i.e., if $\ell_e(x)$ is the latency function of an edge $e$, we replace it by $\hat{\ell}_e(x)$ with $\ell_e(x) \le \hat{\ell}_e(x)$ for all $x$. Then an adversary fixes a demand rate as input. The engineered Price of Anarchy of the mechanism is defined as the worst-case ratio of the Nash social cost in the modified network over the optimal social cost in the original network. Formally, if $\CM(r)$ denotes the cost of the worst Nash flow in the modified network for rate $r$ and $\Copt(r)$ denotes the cost of the optimal flow in the original network for the same rate then [\ePoA = \max_{r \ge 0} \frac{\CM(r)}{\Copt(r)}.] We first exhibit a simple coordination mechanism that achieves for any network of parallel links an engineered Price of Anarchy strictly less than 4/3. For the case of two parallel links our basic mechanism gives 5/4 = 1.25. Then, for the case of two parallel links...

ABSTRACT The paper is dedicated to the study of transactions governances adopted by fuel distributors with retailers stations, according to the theoretical approach of the New Institutional Economics. The work conducted field interviews with 25 distribution companies, which account for approximately 80% of domestic sales of gasoline and ethanol. The results suggest that the governance structures differ by asset specificity and that hybrid governances are the most frequent. The conclusions also indicate that the size of distributors is decisive in the choice of coordination mechanisms used and that the delay in enforcing contracts is the main cause of the emergence of complementary mechanisms, their use being primarily directed to the protection of specific assets in transactions.; RESUMO Neste trabalho, o foco é o estudo das governanças das transações adotadas pelas distribuidoras de combustíveis com os postos varejistas, segundo abordagem teórica da nova economia institucional (NEI).

The good performance of a set of computer systems based on agents depends on the coherence degree and coordination between their activities. The study of coordination problem is an important topic for designers and researchers in the multi-agents systems field. There are several coordination mechanisms in the current literature, being the auction and the contract net the most popular ones. These mechanisms allow the agents to allocate resources and tasks to achieve their objectives. This paper aims to present formal models of the auction and the contract net as coordination mechanisms in multi-agents systems based on FIPA (Foundation for Intelligent Physical Agents) Protocols. Mathematical equations describe the different parameters characterizing the auction and the contract net mechanisms; they allow define a generic structure of each mechanism and groups of agents can create several instances of them to coordinate their needs
