Beyond words: Testing alignment among inter-organizational performance measures

Purpose: This paper seeks to measure in a quantitative way the degree of alignment among a set of performance measures between two organizations. Design/methodology/approach: This paper extends Venkatraman's test of coalignment to assess the alignment of a set of performance measures governing a contractual inter-organizational relationship. The authors applied the test and present coefficients of misalignment across three sets of measures: those used by a service provider involved in the research, those used by customers contracting the services, and those documented in 11 contracts studied. Findings: Results confirmed a high degree of alignment between target and actual operational performance in the contracts. The alignment of customers' financial objectives and contracts' operational metrics was low. Calculations show poor alignment between the objectives of the provider and the contribution received from the contracts. Research limitations/implications: Some limitations of the conclusions include the small sample of contracts used in the calculations. Further research should include not only actual contracts, but also failed ones. Practical implications: It is possible that misaligned goals, represented in misaligned performance measures, lead to tensions in intra-firm relationships. If these tensions are not addressed properly the relationship could be unstable or terminated prematurely. This method of measuring alignment could detect early potential dangers in intra-firm relationships. Originality/value: This paper extends Venkatraman's test of coalignment to assess the alignment of a set of performance measures governing a contractual inter-organizational relationship. Management researchers and business professionals may use this methodology when exploring degrees of alignment of performance measures in intra-functional and inter-firm relationships. © Emerald Group Publishing Limited.

Competing manufacturers in a retail supply chain: On contractual form and coordination

It is common for a retailer to sell products from competing manufacturers. How then should the firms manage their contract negotiations? The supply chain coordination literature focuses either on a single manufacturer selling to a single retailer or one manufacturer selling to many (possibly competing) retailers. We find that some key conclusions from those market structures do not apply in our setting, where multiple manufacturers sell through a single retailer. We allow the manufacturers to compete for the retailer's business using one of three types of contracts: a wholesale-price contract, a quantity-discount contract, or a two-part tariff. It is well known that the latter two, more sophisticated contracts enable the manufacturer to coordinate the supply chain, thereby maximizing the profits available to the firms. More importantly, they allow the manufacturer to extract rents from the retailer, in theory allowing the manufacturer to leave the retailer with only her reservation profit. However, we show that in our market structure these two sophisticated contracts force the manufacturers to compete more aggressively relative to when they only offer wholesale-price contracts, and this may leave them worse off and the retailer substantially better off. In other words, although in a serial supply chain a retailer may have just cause to fear quantity discounts and two-part tariffs, a retailer may actually prefer those contracts when offered by competing manufacturers. We conclude that the properties a contractual form exhibits in a one-manufacturer supply chain may not carry over to the realistic setting in which multiple manufacturers must compete to sell their goods through the same retailer. © 2010 INFORMS.

Contratos públicos adjudicados a sociedades cooperativas en el País Vasco entre 2010 y 2012

La Contratación Pública constituye una fuente muy importante de la demanda de bienes y servicios, especialmente en la Comunidad Autónoma del País Vasco en donde el Gobierno Autonómico, también llamado la Administración General Vasca, desarrolla un papel capital como impulsor de dicha contratación pública. Por otro lado, la Economía Social, y especialmente el movimiento cooperativo, tiene en ese mismo ámbito geográfico un papel de gran peso en el conjunto de la Economía Vasca, por sus cifras de empleo y aportación al PIB, así como por tradición y arraigo social. Cabe preguntarse en tal caso, cuál es el papel que desempeñan las cooperativas en la Contratación Pública en aquella Comunidad Autónoma, cómo y cuáles son los contratos de los que resultan adjudicatarias, qué importes suponen esos contratos para las cuentas públicas y, en definitiva, si su papel de adjudicatarias se corresponde con el que desempeñan en el conjunto de la Economía Vasca. Del examen de los contratos publicados en el Perfil del Contratante del Gobierno Vasco, se obtienen datos suficientes que, una vez procesados y analizados, se visualizan en tablas y porcentajes que constituyen la base de un diagnóstico que responde a las preguntas planteadas y evidencia la situación de debilidad de las cooperativas en el campo de la contratación pública vasca.

A decision-support system based on particle swarm optimization for multiperiod hedging in electricity markets

This paper proposes a particle swarm optimization (PSO) approach to support electricity producers for multiperiod optimal contract allocation. The producer risk preference is stated by a utility function (U) expressing the tradeoff between the expectation and variance of the return. Variance estimation and expected return are based on a forecasted scenario interval determined by a price range forecasting model developed by the authors. A certain confidence level is associated to each forecasted scenario interval. The proposed model makes use of contracts with physical (spot and forward) and financial (options) settlement. PSO performance was evaluated by comparing it with a genetic algorithm-based approach. This model can be used by producers in deregulated electricity markets but can easily be adapted to load serving entities and retailers. Moreover, it can easily be adapted to the use of other type of contracts.

A long-term risk management tool for electricity markets using swarm intelligence

This paper addresses the optimal involvement in derivatives electricity markets of a power producer to hedge against the pool price volatility. To achieve this aim, a swarm intelligence meta-heuristic optimization technique for long-term risk management tool is proposed. This tool investigates the long-term opportunities for risk hedging available for electric power producers through the use of contracts with physical (spot and forward contracts) and financial (options contracts) settlement. The producer risk preference is formulated as a utility function (U) expressing the trade-off between the expectation and the variance of the return. Variance of return and the expectation are based on a forecasted scenario interval determined by a long-term price range forecasting model. This model also makes use of particle swarm optimization (PSO) to find the best parameters allow to achieve better forecasting results. On the other hand, the price estimation depends on load forecasting. This work also presents a regressive long-term load forecast model that make use of PSO to find the best parameters as well as in price estimation. The PSO technique performance has been evaluated by comparison with a Genetic Algorithm (GA) based approach. A case study is presented and the results are discussed taking into account the real price and load historical data from mainland Spanish electricity market demonstrating the effectiveness of the methodology handling this type of problems. Finally, conclusions are dully drawn.

O direito de arrependimento nos contratos celebrados à distância e fora do estabelecimento

This dissertation aims to analyze the right of withdrawal and its implications on distance and off-premises contracts, due to the importance of these contracts in our society. Our main goal is, first of all, to explain the meaning and characteristics of both distance and off-premises contracts and the reason why a right of withdrawal is granted. Secondly, we intend to explain all of the relevant aspects related to this right, such as its legal concept and main characteristics, the origin and evolution of the right of withdrawal on both European and Portuguese legislation, its implications in the contracting parties and, finally, a brief analysis of the applicable law. In a nutshell, the right of withdrawal allows the consumer to withdraw from a distance or off-premises contract, unilaterally, without having to indicate any motive to justify the decision, after a cooling-off period of 14 calendar days. In these two types of contracts such right exists due to the reasons or circumstances that lead to the conclusion of the contract.

A protecção jurídica do consumidor em Angola

The scope of the present work is to study the legal protection conferred upon the consumer in Angola, especially as regards electronic communication agreements. Its purpose is to promote consumers’ rights and contribute to its defence given the relatively privileged position of professionals in their relationship with consumers. With this in mind, we have made a description of the Consumer Law in Angola based on the Angolan Constitution (as the law that establishes the fundamental rights and guarantees of citizens) and on the Consumer’s Defence Law, which, as the basic law regarding consumers’ rights, provides the framework for this dissertation. We have analysed several aspects relating to consumer relationships, starting from its concept and rights of consumers and covering the legal and contractual mechanisms put in place for their protection. We have also analysed the Advertising Law with a view to better understand consumer’s rights before advertising campaigns carried out by professionals whilst promoting their goods and services and, additionally, to understand the duties and principles that shall be complied with in such campaigns with the purpose to protect the rights and interests of consumers. From a criminal point of view, we have briefly covered the crimes against consumers provided for in the Penal Code and the Law of Infractions against the Economy. In the second part of this work, we have summarised the institutions that protect the rights and interests of consumers, which include the Public Prosecutor Office, the National Institute for the Defence of the Consumers and the Consumers’ Associations. The third and last part of this work covers electronic communications agreements. Given the fact that there is no specific legislation in this matter, our analysis was based on the Civil Code – specifically the part relating to contracts – the Law on General Contractual Terms and Conditions and the Consumer’s Defence Law. We have analysed the formation of contracts, compliance and consumers’ rights resulting from contract breach. We further have appealed to the Angolan legislator to legislate certain aspects of consumer relationships, especially those where breach of consumers’ rights are blatant and facilitated by the lack of specific laws addressing such cases.

Wage Flexibility and Contract Structure in Germany

In this paper, we look at how labor market conditions at different points during the tenure of individuals with firms are correlated with current earnings. Using data on individuals from the German Socioeconomic Panel for the 1985-1994 period, we find that both the contemporaneous unemployment rate and prior values of the unemployment rate are significantly correlated with current earnings, contrary to results for the American labor market. Estimated elasticities vary between 9 and 15 percent for the elasticity of earnings with respect to current unemployment rates, and between 6 and 10 percent with respect to unemployment rates at the start of current firm tenure. Moreover, whereas local unemployment rates determine levels of earnings, national rates influence contemporaneous variations in earnings. We interpret this result as evidence that German unions do, in fact, bargain over wages and employment, but that models of individualistic contracts, such as the implicit contract model, may explain some of the observed wage drift and longer-term wage movements reasonably well. Furthermore, we explore the heterogeneity of contracts over a variety of worker and job characteristics. In particular, we find evidence that contracts differ across firm size and worker type. Workers of large firms are remarkably more insulated from the job market than workers for any other type of firm, indicating the importance of internal job markets.

Standardized Latin and Medieval Economic Growth

Traditional explanations for Western Europe's demographic growth in the High Middle Ages are unable to explain the rise in per-capita income that accompanied observed population changes. Here, we examine the hypothesis that an innovation in information technology changed the optimal structure of contracts and raised the productivity of human capital. We present historical evidence for this thesis, offer a theoretical explanation based on transaction costs, and test the theory's predictions with data on urban demographic growth. We find that the information-technology hypothesis significantly increases the capacity of the neoclassical growth model to explain European economic expansion between 1000 and 1300.

Essais sur la conception de mécanismes et les enchères

Cette thèse est composée de trois essais liés à la conception de mécanisme et aux enchères. Dans le premier essai j'étudie la conception de mécanismes bayésiens efficaces dans des environnements où les fonctions d'utilité des agents dépendent de l'alternative choisie même lorsque ceux-ci ne participent pas au mécanisme. En plus d'une règle d'attribution et d'une règle de paiement le planificateur peut proférer des menaces afin d'inciter les agents à participer au mécanisme et de maximiser son propre surplus; Le planificateur peut présumer du type d'un agent qui ne participe pas. Je prouve que la solution du problème de conception peut être trouvée par un choix max-min des types présumés et des menaces. J'applique ceci à la conception d'une enchère multiple efficace lorsque la possession du bien par un acheteur a des externalités négatives sur les autres acheteurs. Le deuxième essai considère la règle du juste retour employée par l'agence spatiale européenne (ESA). Elle assure à chaque état membre un retour proportionnel à sa contribution, sous forme de contrats attribués à des sociétés venant de cet état. La règle du juste retour est en conflit avec le principe de la libre concurrence puisque des contrats ne sont pas nécessairement attribués aux sociétés qui font les offres les plus basses. Ceci a soulevé des discussions sur l'utilisation de cette règle: les grands états ayant des programmes spatiaux nationaux forts, voient sa stricte utilisation comme un obstacle à la compétitivité et à la rentabilité. Apriori cette règle semble plus coûteuse à l'agence que les enchères traditionnelles. Nous prouvons au contraire qu'une implémentation appropriée de la règle du juste retour peut la rendre moins coûteuse que des enchères traditionnelles de libre concurrence. Nous considérons le cas de l'information complète où les niveaux de technologie des firmes sont de notoriété publique, et le cas de l'information incomplète où les sociétés observent en privée leurs coûts de production. Enfin, dans le troisième essai je dérive un mécanisme optimal d'appel d'offre dans un environnement où un acheteur d'articles hétérogènes fait face a de potentiels fournisseurs de différents groupes, et est contraint de choisir une liste de gagnants qui est compatible avec des quotas assignés aux différents groupes. La règle optimale d'attribution consiste à assigner des niveaux de priorité aux fournisseurs sur la base des coûts individuels qu'ils rapportent au décideur. La manière dont ces niveaux de priorité sont déterminés est subjective mais connue de tous avant le déroulement de l'appel d'offre. Les différents coûts rapportés induisent des scores pour chaque liste potentielle de gagnant. Les articles sont alors achetés à la liste ayant les meilleurs scores, s'il n'est pas plus grand que la valeur de l'acheteur. Je montre également qu'en général il n'est pas optimal d'acheter les articles par des enchères séparées.

Investir en République Populaire de Chine : l'environnement légal et les formes juridiques d'entreprises

L'économie de la Chine a connu au cours des trois dernières décennies une effervescence sans précédent. Dorénavant ouvert sur le monde, ce nouveau marché de près de 1,3 milliard d'individus possède un potentiel commercial et des perspectives de croissance n'ayant aucun équivalent en Occident. Toutefois, partir à la conquête de l'Empire du Milieu peut s'avérer être une aventure périlleuse pour celui qui ne maîtrise pas le cadre contextuel et légal dans lequel les affaires s'opèrent en ces lieux. Le présent mémoire se veut une étude en deux parties des considérations afin de mener à terme avec succès un projet d'investissement en sol chinois. Dans un premier temps, la présente étude tente de démystifier le climat économique, social et légal entourant le monde des affaires en Chine. L'investisseur étranger a tout intérêt à comprendre cet environnement dans lequel nos repères occidentaux sont parfois inexistants. Il s'agit donc, initialement, de comprendre l'évolution récente de ce pays et les transformations profondes que la Chine a connues dans les dernières décennies. Du socialisme à l'économie de marché, le plus grand marché potentiel sur terre s'est ouvert progressivement sur le monde. Sans délai, l'investissement étranger a alors afflué massivement en ces lieux. Fort de l'évolution de son environnement légal, qui se poursuit d'ailleurs toujours à l'heure actuelle, quels sont les principaux enjeux et défis pour un investisseur étranger en Chine? Parmi différentes considérations, l'investisseur étranger doit s'intéresser particulièrement à la place qu'occupent les autorités gouvernementales dans les transactions privées, à la force obligatoire des ententes commerciales et à la résolution de conflits éventuels. Dans un second temps, la présente étude couvre les principales formes juridiques d'investissement accessibles aux investisseurs étrangers afin d'exploiter ou de participer à l'exploitation d'une entreprise en sol chinois. Il s'agit, pour chacune d'entre elles, d'analyser le droit positif posé par le législateur ainsi que de le compléter avec certains éléments pratiques soulevés par des observateurs en la matière. Il s'ensuivra une analyse des différents mécanismes d'acquisition d'entreprise par les investisseurs étrangers. Ultimement, l'étude de cette seconde partie mènera à une analyse comparative des incidences pratiques relativement aux différentes formes d'établissement ou d'acquisition d'entreprise.
