Transaction costs: an empirical analysis of their relationship with investment and foreign direct investment

As stated by the New Institutional Economics theory, transaction costs play a relevant role in economics and, according to the extent of such costs, agents make investment decisions. Actually, transaction costs may represent a disincentive to entrepreneurship. This work aims to verify whether transaction costs are related to investment rate and foreign direct investment rate (FDI) in different business environments. The results suggest that foreign investors do not have precise information about other countries as domestic investors do; as it is observed, only the relation between transaction costs and investment rate is significant. Furthermore, there is evidence that the business environments of BRIC countries are less developed when compared to business environments of other countries in the study

INTERNATIONALIZATION OF STATE-OWNED ENTERPRISES THROUGH FOREIGN DIRECT INVESTMENT

ABSTRACT State-owned enterprises (SOEs) are created to focus on domestic needs, and yet recent evidence points to increasing outward foreign direct investment by SOEs. Existing International Business (IB) theories focus on efficiency-based motives for internationalization; therefore, they do not fully capture SOEs' internalization dynamics, which are driven largely by political factors and social welfare considerations. We integrate public management and IB theories to develop propositions that combine these questions: why SOEs internationalize; what are their motivations; and what are the main managerial outcomes of SOEs' internationalization. Our findings suggest that SOEs display little hesitancy in entering international markets, and that SOE international expansion is not contradictory with the goals of state-ownership if the purpose is to adjust the company to changing institutional environments both in the domestic and international markets. Our propositions about SOE internationalization are based on an in-depth case study of the outward foreign direct investment conducted by Brazil's Petrobras over the past three decades.

Property and age organisation among an East African pastoralist group

Estudos sobre sistemas etários na África Oriental têm focado principalmente as regras que regulam recrutamento, com ênfase ao modo em que se mantém a autoridade e os cargos políticos, assim como à natureza não-militar e não-política dos sistemas etários. Apesar de contribuírem enormemente para a nossa compreensão das organizações etárias na região, esses estudos não lidam explicitamente com a questão da propriedade e com o modo em que ela constitui um dos principais focos para atividades de organizações etárias. De fato, quando se menciona a propriedade, ela é vista em função das famílias e, portanto, do parentesco. Apresentando e discutindo uma variedade de casos envolvendo o modo em que a propriedade é tratada por lideranças de um conjunto etário/geracional e residentes Hor e não-Hor do território Hor, este estudo conclui que a posse, o uso e controle de recursos não constitui um assunto que pertence exclusivamente à esfera de grupos de parentesco; trata-se também de uma questão central para organizações etárias. Apesar de haver, aparentemente, alguma ambigüidade decorrente da ênfase equilibrada que os Hor dedicam ao parentesco e às categorias etárias e suas complementaridades em assuntos relacionados à economia, à religião e ao direito, dados referentes aos Hor revelam uma tendência a tratar questões referentes ao uso de recursos cruciais em termos de organização etária. Trata-se de um estudo sobre os Hor (Arbore), um povo pastoril do Sudoeste da Etiópia.

Análise de um projecto de investimento imobiliário de habitação: conjunto de moradias geminadas

O presente trabalho refere-se a um projecto real de investimento imobiliário, relativo à construção e comercialização de duas moradias geminadas destinadas a habitação. Este estudo permite ao promotor avaliar o seu interesse económico, caracterizar oportunidades e identificar factores de risco, permitindo uma tomada de decisão baseada em estudos económicos objectivos e fundamentados, e não apenas pela sua intuição. Após a pesquisa sobre o estado de conhecimento deste tema, iniciou-se o estudo do projecto, caracterizando-o numa fase inicial, com a realização de um estudo prévio da sua viabilidade económica, recorrendo a métodos simplificados para a obtenção dos parâmetros de análise necessários, como sejam, os custo do terreno e da construção, a duração da obra, o PVT do imóvel, e a distribuição temporal dos custos e receitas. É então realizada a análise com base em descontos de fluxos de caixa, para determinar a rendibilidade do projecto, através dos parâmetros de decisão VAL e TIR. Concluindo-se que o projecto é economicamente viável, inicia-se a obra e apuram-se os valores reais dos diversos parâmetros de análise, ficando no final com as variáveis estimadas do PVT e do tempo necessário à comercialização do imóvel. É também abordada a importância da gestão coordenação e fiscalização da obra. Com os valores reais obtidos são traçados diversos cenários, analisado o recurso a capital alheio, às variações no PVT e no tempo necessário para a comercialização do imóvel e a possibilidade de arrendamento com posterior venda. A análise do projecto segundo esses cenários, permite obter medidas de rendibilidade e compará-los. É então feita a comparação entre as rendibilidades dos vários cenários e retiradas as conclusões sobre os resultados obtidos. Para melhor compreensão dos resultados, é feita uma abordagem à crise imobiliária sentida em Portugal e à possibilidade do uso da permuta imobiliária para facilitar a realização dos negócios imobiliários. No final, serão realizadas recomendações e propostas de melhoria para estudos que possam ser relevantes para o tema e dar uma possível continuidade a este trabalho.

Investment optimization in distribution network based on fuzzy outage parameters

This paper presents a methodology that aims to increase the probability of delivering power to any load point of the electrical distribution system by identifying new investments in distribution components. The methodology is based on statistical failure and repair data of the distribution power system components and it uses fuzzy-probabilistic modelling for system component outage parameters. Fuzzy membership functions of system component outage parameters are obtained by statistical records. A mixed integer non-linear optimization technique is developed to identify adequate investments in distribution networks components that allow increasing the availability level for any customer in the distribution system at minimum cost for the system operator. To illustrate the application of the proposed methodology, the paper includes a case study that considers a real distribution network.

Residential property loans and performance during property price booms: evidence from European banks

Understanding the performance of banks is of the utmost relevance, because of the impact of this sector on economic growth and financial stability. Of all the different assets that make up a bank portfolio, the residential mortgage loans constitute one of its main. Using the dynamic panel data method, we analyse the influence of residential mortgage loans on bank profitability and risk, using a sample of 555 banks in the European Union (EU-15), over the period from 1995 to 2008. We find that banks with larger weights of residential mortgage loans show lower credit risk in good times. This result explains why banks rush to lend on property during booms due to the positive effects it has on credit risk. The results show further that credit risk and profitability are lower during the upturn in the residential property price cycle. The results also reveal the existence of a non-linear relationship (U-shaped marginal effect), as a function of bank’s risk, between profitability and the residential mortgage loans exposure. For those banks that have high credit risk, a large exposure of residential mortgage loans is associated with higher risk-adjusted profitability, through lower risk. For banks with a moderate/low credit risk, the effects of higher residential mortgage loan exposure on its risk-adjusted profitability are also positive or marginally positive.

Solution enthalpies of 1,4-dioxane: Study of solvent effects through quantitative structure-property relationships

Solution enthalpies of 1,4-dioxane have been obtained in 15 protic and aprotic solvents at 298.15 K. Breaking the overall process through the use of Solomonov's methodology the cavity term was calculated and interaction enthalpies (Delta H-int) were determined. Main factors involved in the interaction enthalpy have been identified and quantified using a QSPR approach based on the TAKA model equation. The relevant descriptors were found to be pi* and beta, which showed, respectively, exothermic and endothermic contributions. The magnitude of pi* coefficient points toward non-specific solute-solvent interactions playing a major role in the solution process. The positive value of the beta coefficient reflects the endothermic character of the solvents' hydrogen bond acceptor (HBA) basicity contribution, indicating that solvent molecules engaged in hydrogen bonding preferentially interact with each other rather than with 1,4-dioxane.

Aquacultura: estudo das condições ambientais internas de uma instalação

A aquacultura desempenha, actualmente, um papel fundamental no abastecimento de proteína animal de elevada qualidade. Nesta dissertação foi elaborado um projecto de uma unidade de piscicultura semi-intensiva de enguia, robalo, dourada e linguado e em regime extensivo a ostra. A unidade está localizada na Ria de Aveiro, na propriedade Ilha do Poço, com uma área total de 54,3 hectares. A execução de um projecto de aquacultura é um trabalho multidisciplinar que necessita a mobilização de diferentes recursos e conhecimentos. Os projectos de aquicultura estão directamente relacionados com o local de instalação da unidade e podem ser negativamente afectados pela poluição, por factores económicos locais ou por factores sociais que coloquem em risco o sucesso desta actividade económica. O principal objectivo desta dissertação foi o estudo de crescimento das espécies, taxa de alimentação, qualidade da água à entrada e saída da aquicultura, o consumo de oxigénio pelas espécies e o oxigénio necessário para oxidar a amónia em nitrato, o estudo de arejamento pelo vento, a necessidade de arejamento mecânico nos tanques de engorda e por fim a análise de investimento do projecto. Os valores obtidos para o tempo de crescimento das espécies até atingir o peso comercial foram, para a enguia 2,25anos, para a dourada 1,5 anos, para o robalo 2 anos, para o linguado 2,25 anos e para a ostra 1ano. Os índices de conversão alimentar (ICA) obtidos para as espécies foram os seguintes: 1 para a enguia, 1,24 para o robalo, 1,2 para a dourada e 1,58 para o linguado. Relativamente à concentração de amónia nos tanques de engorda, a espécie robalo apresenta o maior valor (0,3mg/L) por tanque. O arejamento natural dos tanques apenas é conseguido se o vento tiver uma velocidade de 20m/s. Por essa razão, e para garantir o arejamento requerido, serão necessários pelo menos 46 arejadores mecânicos com potência de 6kW a funcionar 24/24 horas. Para a taxa ponderada obteve-se um valor de 11,80%. O valor obtido para o VAL foi de 2.036.862 € e para a TIR, de 27,95%. O tempo necessário para que o investidor efectue o reembolso do capital investido no projecto é de 5,5 anos. O índice de rentabilidade tem um valor de 1,83 o que significa que o projecto é rentável.

Investment focused strategies in electricity markets using the ITEM-game simulator

This paper presents a methodology to establish investment and trading strategies of a power generation company. These strategies are integrated in the ITEM-Game simulator in order to test their results when played against defined strategies used by other players. The developed strategies are focused on investment decisions, although trading strategies are also implemented to obtain base case results. Two cases are studied considering three players with the same trading strategy. In case 1, all players also have the same investment strategy driven by a market target share. In case 2, player 1 has an improved investment strategy with a target share twice of the target of players 2 and 3. Results put in evidence the influence of the CO2 and fuel prices in the company investment decision. It is also observed the influence of the budget constraint which might prevent the player to take the desired investment decision.

Incorporating sustainability into a chemical company’s modus operandi

The intent of this dissertation is to review relevant existing management systems and chemical industry initiatives to identify synergies, overlaps and gaps with Sustainability best practices, to map the barriers to the incorporation of Sustainability and formulate recommendations to facilitate execution of Sustainability practices within existing management systems. A chemical industry Sustainability survey was conducted through APEQ, the Portuguese association of chemical companies, which constitutes the first baseline on the topic for this national industry association. The commonly used international standards and the Responsible Care® (RC) initiative were cross-referenced against the United Nations Global Compact Assessment Tool. Guidance on how to incorporate Sustainability into a company‘s modus operandi was collapsed into Sustainability Playbooks. The survey revealed that 73% of the APEQ member companies that participated in the survey have a Sustainability Plan. Both large and small/medium APEQ member companies see the market not willing to pay extra for ‗greener‘ products as one of the main barriers. APEQ large enterprise see complexity of implementation and low return on investment as the other most significant barriers while small/medium enterprise respond that the difficulty to predict customer sustainability needs is the other most significant barrier. Amongst many other insights from this survey reported to APEQ, Life Cycle Assessment practices were found to have a low level of implementation and were also considered of low importance, thus identifying a very important opportunity in Sustainability practices to be addressed by APEQ. Two hundred and seventy three assessment points from United Nations Global Compact Assessment Tool plus five additional items were cross-referenced with international standard requirements. With the authorization of the intellectual property owners, the United Nations Global Compact Assessment Tool was modified to introduce actionable recommendations for each gap identified by management standard. This tool was automated to output specific recommendations for 63 possible combinations after simply selecting from a list of commonly used management standards and the RC initiative. Finally this modified tool was introduced into Playbooks for Incorporation of Sustainability at two levels: a ―Get Started Playbook‖ for beginners or small/medium size enterprise and an ―Advanced Playbook‖ as a second advancement stage or for large enterprise.
