Quais os determinantes da escolha do arranjo contratual nas transações entre produtores e processadores de carne bovina no Uruguai? A pergunta problema se insere no estudo dos mecanismos de coordenação associados ao problema do controle da produção para dar respostas às novas preocupações e demandas dos consumidores. A coordenação do sistema agroindustrial (SAG) da carne bovina uruguaia adquire maior relevância, não apenas para dar garantias de produtos seguros e com atributos específicos de qualidade aos consumidores, mas também para reagir rapidamente frente a mudanças e para explorar as oportunidades que o acesso a mercados de alto valor oferece (exporta-se 75% da produção). Coexistem diversos arranjos contratuais, dentre os quais o arranjo direto e via intermediário são os dominantes. Abordagem teórica: Economia dos Custos de Transação que focaliza a compreensão dos motivos que explicam a emergência e adaptação de arranjos contratuais em resposta aos desafios de ganhos de eficiência ?economizando? nos custos de realização das transações entre os agentes econômicos. Método: Foram analisadas as mudanças no ambiente institucional e organizacional nos mercados finais e no Uruguai; as novas oportunidades e estratégias no SAG da carne bovina; e o SAG uruguaio desde o consumo à produção. De modo particular, analisou-se a transação produtor-processador no que se refere aos arranjos contratuais existentes e às dimensões da transação (especificidade dos ativos físicos e humanos envolvidos na produção e processamento, locacional, freqüência e incerteza). Foram identificados os determinantes da escolha dos arranjos contratuais dominantes (direto e via intermediário). Por último realizou-se um teste estatístico das relações causais identificadas com painel de dados do total das transações realizadas no Uruguai (77.000 transações, 2004/2005). Resultados: Encontrou-se relação estatisticamente significativa entre a escolha do arranjo contratual na transação produtor-processador e os determinantes identificados. Uma transação tem maior probabilidade de se alinhar com o arranjo contratual direto (mais coordenado) quanto maior o grau de especificidade dos ativos envolvidos na produção e processamento do produto transacionado (ex.: novilhos precoces), quanto menor a distância entre o produtor e o processador, e quanto maior a freqüência das transações entre as partes envolvidas. O arranjo contratual direto facilita a coordenação das transações que envolvem produtos com atributos de maior qualidade. Os intermediários apresentam vantagens em transações de produtos genéricos (menor grau de ativos específicos) e com baixa freqüência de transação entre o produtor e processador envolvido. A busca por qualidade envolve investimentos específicos na produção e processamento e, em conseqüência, maior dependência bilateral entre os agentes dessas atividades. A dinâmica do SAG e o negócio da carne bovina dependem de dois conjuntos de produtos -baixa e alta qualidade- ligados a mercados diferentes. O subsistema que orienta as estratégias na busca de produtos de maior qualidade envolve arranjos mais coordenados. Do presente trabalho decorrem implicações para os atores do SAG e para as políticas públicas setoriais em torno a uma ?estratégia país? com foco em produtos cárnicos de alta qualidade e valor. / What are the determinants of the contractual arrangement choice in the beef producersprocessors transactions in Uruguay? The question refers to the coordination and production control problem. Changes in consumer?s awareness of specific attributes in food products demand information and better coordinated systems. Coordination becomes more important to Uruguay not only to assure quality attributes of products but also to explore market access opportunities and fast adaptation to international and local environmental changes (exports 75% of the beef production). There are different contractual arrangements in the producerprocessor transaction mainly direct channel and through intermediate agent. Theory approach: Transaction Cost Economics offers helpful insights to understand the reason for the development and adaptations of different contractual arrangement moved by transaction cost economizing perspective. Method: empirical analysis focused on the Uruguayan beef agro-industrial system. Analysis integrates (i) institutional and organizational environmental changes on final markets and in Uruguay; identification of new opportunities and strategies in the beef system; analysis of the Uruguayan system from consumption to production. (ii) Analysis of the producer-processor transaction in relation to the contractual arrangement and the dimension of the transaction (asset specificity in the production and processing of the product being transacted, location, frequency of transaction and uncertainty). Identification of the determinants of the main contractual arrangement choice (direct and trough intermediate agent). Finally, an econometric analysis of the causal relation identified (determinants). Data sources: panel data with producers-processors transaction from Uruguayan Agricultural Bureau (77,000 transactions, 2004/05). Results: Statistical significance between the contractual arrangement choice in the beef producer-processors transaction and the determinants identified. The probability of a transaction being aligned with the direct contractual arrangement (more coordinated) increases in transactions with higher asset specificity (e.g.: young steer), lower distance between producer and processor, and with higher frequency of transaction between these agents. The direct contractual arrangement is helpful for the coordination of higher quality products. The intermediate agent presents advantages for generic products transactions (lower asset specificity) and with low frequency of transaction between the producer and processor involved. Seeking for quality involves specific investments by producers and processors and, hence, higher bilateral dependency between these agents. The beef system depends on two sets of products ?higher and lower quality- oriented to markets with different characteristics. The subsystem oriented to higher quality products involves higher coordinated arrangements. The results of this research were extended to implication for the organizations of the beef system and public policies in relation to a ?country strategy? focused on higher quality and value beef products.

The prime objective of a client in a building project is to attain a successful project, a project that has been properly planned, designed and constructed in accordance with plans and specifications, and completed within time and cost originally anticipated. However the success of a building project depends on a number of variables one of them is the way the building team approach conflicts facing the project. This study examines the causes and management approaches of conflicts in building projects in Tanzania. The main objective of the study is to identify issues/areas on which conflicts occur, factors causing them and how conflicts are managed in building projects in Tanzania. As a means to achieve the above objective, the study was structured into two main parts; the first part aimed at mapping up the nature of conflicts in building projects in Tanzania by establishing critical symptoms of conflicts, factors causing them and the approaches used in resolving the conflicts. This was done through literature review, interviews and questionnaire survey. The second part aimed at in-depth study of conflicts from their root cause, how they develop/progress and how they are managed in a real building project setting. Four case studies of building projects were studied for this part. The study found that factors causing conflicts are in several forms. There are those related to the nature of contracts, where the contracts are unclear and ambiguous they give room for contracting parties to develop opportunistic behaviour when post adjustments are needed. There are those factors which are related to role functions when the parties fail to perform as expected. As such the study confirmed that contractual incompleteness and consequent post contract adjustments and opportunistic behaviour of some project participants are root causes of conflicts in building projects in Tanzania. However, the study established that there are sufficient mechanisms to deal with conflicts in the standard forms of building contracts used and when the provisions are against the interests of the parties, the parties resort to amicable resolution approaches. Notwithstanding the availability of mechanisms in the standard forms of contracts to deal with conflicts, the study proposes the framework as a strategy that could reduce effectively the occurrences of conflicts in building projects. / QC 20110223

Problem: The developing business market and the pressure it puts on business gives rise to new fields of business within SCM and logistics. Third party logistics (TPL) services have grown rapidly in importance as an alternative to vertical business integration. The emergence of TPL has brought about interest in the topic by academia, but recent literature reviews express a need for research on TPL relationships where both buyer and provider perspectives are viewed simultaneously, since a majority of previous research has been conducted more from a single organisational viewpoint. Purpose: The purpose of this thesis is to investigate how providers and buyers in TPL relationships adapt and cooperate to develop mutually beneficial and long-term relationships, as well as investigating their willingness and attitudes in this concern. Method: The thesis combines an explanatory and exploratory classification, and performs a qualitative, mono method study of viewpoints on TPL relationships from Swedish and Norwegian providers and buyers that currently are in a TPL relationship. Semi-structured interviews are conducted with four providers and three buyers. The findings are analysed and interpreted in light of a theoretical framework developed from the literature review, which in the analysis is applied in a TPL context to extend the understanding of TPL relationships. Conclusions: Willingness to adapt and cooperate in TPL relationships is connected with the parties’ perceived potential for economic gain and also with being able to trust the other party. Buyers emphasise the need for providers to have knowledge about the buyers’ business. Providers emphasise the need for buyers to be knowledgeable about their own business and for the buyer to fits their solutions. Attitudes: Both parties emphasise communication as crucial for the development of mutual benefits. Buyers adapt to providers’ standards as far as possible. Providers seem to want buyers to adapt to their solutions to gain economies of scale, and therefore appear reluctant to make relationship-specific investments. The use of contracts in the TPL context appears to contradict literature in that contracts work as a foundation for building trust, as well as for reducing opportunistic and operational risk. In practice, both providers and buyers highlight the use of integrated IT-solutions as a means of adapting to each other. Regular operational meetings are emphasised as part of the practical cooperation to develop the relationship’s future and to discuss day-to-day issues.

Leading up to the time just before the economic and global meltdown of 2008, economist and theorist forecasted as early as 2005 about and impending financial crisis that would affect every sector of the business and financial community. As we discover in more dramatic detail that family firms are occupying a big percentage in small to medium size enterprises, we wondered how they would be affected by such a high degree of uncertainty and volatility in the financial markets during the economic crisis. With these factors in mind, we would like to see it in a more day–to–day, practical application within family firms. In the supply chain or procurement life-cycle, firms need to receive products and services from the supplier and the supplier will in turn offer those same services to the customer. The firm will tend to structure this tradeoff with a contractual structure to guarantee achievement of mutual benefit and economic objectives of the firm. On the other hand, family firms are famous for being distinguish from non-family firms in their non-economic objective they persuade along their businesses. Considering these two different logics that affects the decision of the firm in structuring contractual governance with the exchanging party. We ask the following questions in our purpose.

ABSTRACT As the progress of information technology, the trend of globalization market and dramatic market competition, human resource can be the only source of sustaining a competitive advantage for organizations. It is not all employees who possess knowledge and skills of core resources for firms. It is the fundamental work for human resource management for firms to improve employment management of human resource. Given pressures for both efficiency and flexibility, in addition to the use of internal full-time employees, firms are use external workers, such as temporary employees, contract laborers, consultant etc. The fact highlights that human resource management can be divided to make or buy decisions. It would be more efficient employment to hire at employee's characteristic. The related academic is less and lack of a systematic framework for carrying for employment management. This study, develop a human resource architecture based transaction cost economics, human capital, resource-based view and the academic of Lepak & Snell (1999). The conclusions are: 1.When human resource are both valuable and unique, firms should internally develop human resource and would rely on a commitment-based human resource configuration. 2. When human resource is valuable but not unique, firms should acquire human resource from labor market and would rely on a market-based human resource configuration.3. When human resource is not valuable and unique, firms should use contractual human resource and would rely on a compliance-based human resource configuration.4. When human resource is unique but not valuable, firms should use alliance and would rely on a collaborative-based human resource configuration.

In the past, firms based on economics of scale, capital intensive, mass advertisements, customers service and product quality had changed into creative excellent human resource. Human resource could truly be the only source of sustaining competitive advantage for firms. The related academic about strategic human resource management especially integrative employment and development is less for reference in Taiwan. More over, operations and practices in strategic human resource management are usually not made known to the public because of executives¡¦ hesitation. Thus, these impacts had influenced the empirical studies. Based mainly on transaction cost economics, human capital, resource based view, the purpose of research is to discover an integrated architecture for strategic human resource employment and development by examining high-technology facility industries. The thesis will share the successful experiences of applied human resource management to firms and for reference to the industries, and contribute to the construction of strategic human resource management theory.

The role of governments in the internationalization of the firm had early recognition in prominent seminal studies in international business, such as Hymer’s thesis or the Uppsala Model, though the interaction between multinationals and governments has attracted scarce attention. As such, the main stream of economics and management studies have focused on internationalization essentially as an issue of the firm, wherein the multinationals’ interaction with the environment is limited to a business-industrial scope of suppliers, clients, and competitors. In a different direction, this thesis includes the political setting and studies the beneficial side of governments in the internationalization process of the firm. With this purpose, the present dissertation proposes a conceptual framework based on Johanson and Vahlne’s (1977) internationalization process model, complemented with Williamson’s (1975) Transaction Costs Economics, and encompassed by conceptual insights from institutional studies related to international business. Specifically, the role of governments in the internationalization process is examined through the variances of the relation between knowledge and commitment at the micro, meso, and macro level. The structure of the thesis reflects the multilevel approach, integrating one conceptual and three empirical papers, each of which dealing with a particular level of analysis. Through the aggregation of each paper’s intrinsic contribution, the dissertation’s summary offers a wide view on the internationalization phenomena, adding the political elements to the industrial-business elements of the environment. Overall, internationalization is conceptualized as a process of interaction with the business environment, whereas the public nature of political elements induces the compromise of combining activities between firms and governments. Evidence gives the ground to conclude that internationalization is not a game played just between firms, or, even, between firms and markets, but also with and within governments.

Saskatchewan has good growing conditions, much land and water resources, minimal pest pressure and the expertise necessary for growing high-quality commercial vegetables. Statistics show, however, that commercial vegetable production occupies a relatively small place in the agricultural economy of Saskatchewan. Saskatchewan production accounts for less than 10 per cent of the total provincial market for fresh vegetables, the other supplies of fresh vegetables marketed in Saskatchewan come from sources outside of the province and imports from the southern United States, Mexico, and other warm regions. The majority of Saskatchewan produced vegetables are sold through market gardens, farmers’ markets and consumer contract sales. In light of the increasing importance of fresh vegetable demand, examining the role of a new marketing organization in the province is important as it might bring about major realignment of the Saskatchewan fresh produce market. Recently, a project supported by the Agriculture Council of Saskatchewan Inc. (ACS) encouraged producers to organize themselves into picking zones and to work together to supply larger retail markets. The Grocery People (TGP) (a retailer) has agreed to purchase vegetables grown in Saskatchewan for their distribution centre in Saskatoon. This new organization, Prairie Fresh Food Corporation (PFFC), despite its numerous benefits, will test the farmer participants’ resolve to cooperate rather than proceed alone. This poses a real opportunity for producers to expand and develop the infrastructure required, as produce can be pooled. This study uses Transaction Cost, Agency and Monopolistic Competition theories to analyze the factors that hamper farmers from participating in contracts and taking advantage of these potential opportunities. It considers the advantages and barriers or potential challenges to wholesalers and retailers cooperating with this plan. In particular, an economic model of economies of scale through collective action is developed. The model assumes that small growers can access higher market share through collective action and achieving economies of scale. The results of personal interviews with eleven members of PFFC are presented and analyzed in a case study format. The case study analysis of PFFC reveals that the organization could provide positive benefits to its members in the early period of its establishment. The results show that the market share of the PFFC is still relatively small throughout the province, but its members expect it to expand in the future. The results suggest that high relative prices in the market and trust in the buyer have a positive effect on the probability of farmer participation in the project.

The food processing industry is dominated by large corporations. These firms play a critical role in forming the derived demand faced by agricultural producers, but little is understood about how these companies make strategic choices. Organizational economics provides a framework for exploring the firm's decision process. However, several theories exist in this discipline, operating in fundamentally different ways. This paper examines the two prevalent organizational theories, Transaction Cost Economics and Agency Theory, through a study of the food processing industry. This sector is thoroughly analyzed in order to make predictions from each theory regarding the aspects of capital structure and firm expansion. With accounting data for a sample of food processing firms, these predictions are then tested empirically using an ICAPM model in a cross-section of expected stock returns. Our results indicate that Agency Theory is the relevant organizational model for food manufacturers, making it the appropriate tool for evaluating the actions of these firms in agricultural markets.

Relay networks and cooperative transmission have spurred considerable interest in recent years, promising performance improvements in, e.g., system capacity, robustness and transmission rate. In this thesis, the focus is on the so-called half-duplex relay channels, where in the system, a source node wants to transmit a message to a destination node and a relay node can potentially assist this transmission. The relay is said to be half-duplex in the sense that it cannot transmit and receive at the same time within the same frequency band. It is natural to categorize the potential relaying schemes (operations of the relay node) into two kinds. The relay can either decode the message of the source node, or it can process its received signal without decoding. The thesis investigates various schemes of the second kind and they are termed as ``relaying schemes without decoding.'' The first part of the thesis is devoted to the approach of instantaneous relaying. The instantaneous relaying schemes belong to the relaying schemes without decoding, where the relay node is implemented by a deterministic single-variable function. Both linear and non-linear functions are investigated and it is demonstrated that the functions with sawtooth-like shape give higher achievable rates than other functions investigated. Furthermore, the work is extended to half-duplex multiple-access relay channels, where an extra source node is present. For such channels, the relay's operation is ``instantaneous'' in the sense that it is represented by a deterministic function of two variables. Essentially, the function handles the received signals from the two source nodes, combining them together and transmitting the combined signal to the destination node. Novel functions based on the Archimedean spiral mapping and sawtooth-like functions are proposed and demonstrated to perform well, using achievable rate regions and achievable sum rates of the two source nodes as figures of merit. In the second part of the thesis, the class of relaying schemes without decoding and with memory is investigated, where for such schemes, information theoretic source and channel coding with long codewords is used at the relay node. The two predominant schemes of such kind are the so-called compress-and-forward (CF) and quantize-and-forward (QF) schemes. The achievable rate results of the two schemes and some of their variants are derived for static channels. Furthermore, under the assumption of slow fading channels, with transmitter channel state information (CSIT) not available at the source and relay nodes, outage probabilities, expected rates as well as diversity--multiplexing trade-offs (DMT) of the respective schemes are derived and compared. In addition, to compensate for the loss due to the absence of relay CSIT, a finite-resolution feedback link from the destination node to the source node is designed for the CF and QF schemes to provide the relay node with partial CSIT, and thus, the performance of the respective schemes can be improved. Lastly, the thesis considers the problem of lack of relay CSIT from another viewpoint. The concept of hybrid digital-analog coding, as is first investigated in source-channel coding, is adapted and applied at the relay node. Such relaying schemes are termed hybrid digital-analog relaying schemes and their performance in terms of expected rate is studied. It is shown that the hybrid schemes significantly outperform the conventional digital-only (e.g., the CF scheme) and the analog-only schemes (e.g., the so-called amplify-and-forward scheme). / QC 20110222
