An important issue today is the compatibility of agricultural frontiers, which are driven by economic objectives, with conservationist views. In the Amazon, family farmers are concerned with this issue since they are at the same time actors of the agricultural frontier and considered as potential actors of the preservation of the forest. Through the study of a highly symbolic settlement project in the State of Pará, this paper focuses on the role that family farmers can play in meeting sustainability goals. The central argument which is developed in this paper is that this objective may be achieved when projects do not presuppose social and spatial relationships; rather, it advocates an approach which is attentive to place-making processes. 相似文献

From December 1999, shareholders who disposed of shares in Australian takeovers in exchange for scrip could elect to defer capital gains taxation until the disposal of the shares received. We investigate payment method choice by acquiring firms before and after this regulatory change to assess whether target shareholder capital gains tax liabilities became an important factor considered in choosing the form of payment. The results show that, subsequent to the regulatory change, there is a significantly higher probability that equity will be offered as consideration where target shareholder capital gains are greater. This finding confirms the importance of shareholder level taxation in explaining corporate acquisition structure and adds to previous European and US evidence on factors associated with payment method choice in takeovers. 相似文献

The introduction of the flex-fuel cars in the Brazilian market in 2003 changed considerably the consumer decision-making process. Prior to this date, it was necessary to choose the automobile type only by gasoline or by ethanol fuel; today it is possible to choose a car type with both fuel options. This flexibility generates economic advantages for his owner, but what are the financial benefits of a flex-fuel car in comparison with a car using only gasoline? Geographically, where is the owner of the benefits from this flexibility located? This article presents an empirical application of the Real Options Theory in the analysis of the flex-fuel car option for five geographic Brazilian regions: Northern, Northeastern, Central-Western, Southeastern and Southern. The regional price differences as well as the consumer preferences of these regions were met. For this purpose, historical fuel prices were considered stochastic and following a Mean Reverting Stochastic process. The prediction and option values were generated by a Monte Carlo simulation. The results indicated that the option embedded on the Brazilian flex-fuel car adds considerable value to the owner in all regions and car models considered, with the Southeastern Region receiving most benefits by the flex option. 相似文献

ABSTRACT This paper analyzes the relationship between withdrawals from Brazilian open retirement funds, portfolio composition (fixed income or equity) and frequency of statement sending (monthly, quarterly, semiannually or annually). Our results indicate that equity retirement plans present a lower withdrawal index when compared to that of fixed income plans. Furthermore, the higher the statement sending frequency, the lower the withdrawals from open retirement plans. However, withdrawals from equity retirement plans tend to increase when statements are sent to investors more frequently. These phenomena can be explained by behaviorist theories, such as the concept of myopic loss aversion. In a context where loss aversion is present, the more frequently the investor evaluates his or her portfolio, or the shorter the investment horizon, the less attractive he or she will find investment in assets with a high rate of return and risk, such as equities. This behavior occurs not only regarding short-term investments, but also traditional long-term assets such as equity retirement plans. RESUMEN. Este estudio analiza la relación existente entre las retiradas de los fondos abiertos de jubilación brasileños, la composición de la cartera (ingreso fijo o patrimonio), y la frecuencia del envío de estados financieros (mensual, trimestral, semestral o anualmente). Nuestros resultados indican que los planes de jubilación patrimonial tienen un índice de retirada menor, en comparación con los planes de ingreso fijo. Además, cuanto mayor la frecuencia de los estados financieros, menor es la retirada de los planes abiertos de jubilación. Sin embargo, las retiradas de los planes de jubilación patrimoniales tienden a aumentar cuando los estados se envían a los inversores con más frecuencia. Este fenómeno puede explicarse con las teorías comportamentales, tales como el concepto de la aversión miope a la pérdida. En un contexto donde la aversión a la pérdida es una realidad, cuanto mayor la frecuencia con que el inversor pueda evaluar su carera, o menor el horizonte de inversión, menos atractivas considerará él las inversiones en activos con un alto retorno y riesgo, tal como las acciones. Este comportamiento ocurre no sólo en las inversiones a corto plazo, sino también en los activos a largo plazo, como los planes de jubilación patrimoniales. RESUMO. Este artigo analisa a relação entre as retiradas dos fundos abertos de aposentadoria brasileiros, a composição da carteira (renda fixa ou ações) e a freqüência da remessa de extratos (mensal, trimestral ou semestral). Nossos resultados indicam que os planos de aposentadoria que aplicam em ações apresentam um índice de retirada menor em comparação com os planos de renda fixa. Além disso, quanto maior a freqüência de remessa de extratos, menores as retiradas dos planos abertos de aposentadoria. Entretanto, as retiradas dos planos de aposentadoria que aplicam em ações tendem a aumentar quando o extrato é enviado aos investidores commais freqüência. Esses fenômenos podem ser explicados por teorias behavioristas, como o conceito de aversão míope à perda. Num contexto onde a aversão à perda esteja presente, quanto maior a freqüência com que o investidor avalia a sua carteira, ou quanto menor o horizonte do investimento, menos atraente ele achará o investimento em ativos com alto retorno e risco, como ações. Esse comportamento ocorre não apenas em investimentos a curto prazo, mas também nos ativos tradicionais de longo prazo como os planos de aposentadoria com aplicação em ações. 相似文献

The main objective of this research was to investigate the impacts caused by announcements of mergers and acquisitions (M&As) on the volatility of the returns of Brazilian bank stocks from 1994 to 2015. In order to achieve the proposed objective, this study applied Generalized Autoregressive Conditional Heteroscedastic (GARCH) class models to the series to model their volatility. Our results confirmed the impact of the announcement of M&As on volatility. They suggest that M&A announcements are expected to cause a negative reaction if related to an expansion or a deal involving a less-well known bank, and a positive reaction if it involves well-known bank with good reputation—a higher level of confidence and a lower level of information asymmetry for investors. 相似文献

ABSTRACT This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy. 相似文献

The present research aimed at understanding the process by which firms in a cluster start to export based on systemic interactions, and the process of diffusion of exporting as a business strategy within the cluster. Diffusion was defined, following Rogers’ (1995: 5) seminal work, as ‘the process by which an innovation is communicated through certain channels over time among the members of a social system’. The research method used was industry case studies and the unit of analysis selected was the cluster. Two manufacturing industries were chosen to be investigated, and within each geographic area clusters were identified as the origin of dynamic export growth in the industry. Players in each industrial cluster, as well as other significant actors, were interviewed. Extensive secondary data research was done to study clusters’ historical development. Detailed analysis and a comparison of the experiences permitted the extraction of some general conclusions concerning the similarities and differences between the clusters in terms of the adoption and diffusion of exporting. Results showed that the diffusion of exporting in an industrial cluster is quite similar to the dissemination of technical innovation. Social ties were important to facilitate the diffusion of exporting in one of the clusters studied. Also, the role of domestically-owned flagship firms in leading the internationalization process proved to be important in only one of the clusters, while the role of external actors was fully supported in the two industries studied. Finally, a number of support institutions, private and public, interfered in different stages of the internationalization process. In both industries, the federal government had only a late and limited impact on export initiation and development. 相似文献

This study describes the creation and validation of a multidimensional model which assesses the level of employee satisfaction based on international theoretical models. It utilizes data collected from a sample of 518 public and private company employees during the year 2009 in the city/state of São Paulo, Brazil. In the first stage of the study, 15 independent dimensions were theoretically obtained. In the second stage, five different multiple dimensions were confirmed using structure equation modeling (SEM) technique, thus characterizing general configurations of the organizational climate construct denominated motivation, management philosophy, leadership, people management and nature of work. It is hoped that the model can contribute by enhancing managerial best practices of an organization by attending a major demand for those listed on stock markets, since these companies must periodically provide information on job satisfaction of their employees to maintain or achieve higher levels of corporate governance. 相似文献
