This research investigates the key elements that South African financial services firms consider before making foreign direct investments in Sub-Saharan African (SSA) markets. The results show that South African financial services firms are most strongly influenced by the political and economic stability of the country in question as well as the profitability and long-term sustainability of its specific markets. The degree of available infrastructure in terms of Information and Communication Technology as well as the existence of credible financial systems was also viewed as highly important considerations before investing in SSA. Given the uncertainty and ambiguity of most SSA markets many South African financial services firms prefer to enter existing markets via a majority stakeholder joint venture with a local partner or via a new investment if the market does not currently exist. The nature of the financial services firm also seems to influence the entry method and once in a new country most firms seem to prefer a full service presence. Additionally, the key motives cited for expansion northward were to broaden revenue bases and improve profit margins as well as to stay close to local customers.  相似文献

Despite the increasing importance of Brazil, there has been little documentation of how accounting developed and about the significant formative influences involved. This paper explores the significant influences on Brazilian accounting and the path to the adoption of International Financial Reporting Standards (IFRS). Several important influences are emphasized: the equity theory of the Italian school of accounting in the early 20th century; the birth of the Brazilian accounting profession in 1931 and the certified accountants association in 1946; the impact of US trade and American accounting in the 1950s; and the high rates of inflation that occurred from the beginning of the 1960s. Modern Brazilian accounting had its beginning in the 1970s with the development of the stock market, the reforms of the financial system, and the decrease of tax influences on accounting. The globalization process and the need for Brazilian accounting to converge with international accounting led to the decision to adopt IFRS in 2007.  相似文献

The gamma class of distributions encompasses several important distributions, either as special or limiting cases or through simple transformations. Here we derived closed form and preference free European option pricing formulae for various (transformed) gamma distributions under the general equilibrium RNVR framework. The gamma class of distributions is used historically in hydrology for modelling natural events. Our models can be used to price derivatives associated with these natural phenomena, which will help to encourage greater risk sharing through financial securitization. Our pricing formulae are theoretically sound even if the underlyings and the derivative instruments are not (frequently) traded. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 30:409–431, 2010  相似文献

This article explores alternative changes that could take place in the technology, methodology, and most importantly, the practice of locational decision-making, and is part of a larger scale project aimed at investigating the practical value of artificial intelligence (AI) techniques for strategic decision-making. The research involves comparing the effectiveness of a number of AI paradigms and modelling devices, both with each other and with more conventional computer models.  相似文献

In the supply chain oriented to Industrial 4.0 Scenario the scarcity of studies on Technology Transfer (TT) can be easily observed. TT is a fundamental process, because it steers the absorption and dissemination of technologies towards the various stages of supply chain. The objective of this study is to contextualise TT in the supply chain of Industrial 4.0 Scenario, focusing on the supply, manufacturing industry and final consumer stages. A review of the literature was carried out, using a structured protocol and criteria to compose the bibliographic portfolio. To support the questions presented in this study, the most relevant articles related to the researched topic were thoroughly analyzed. The results infers that in the Industrial 4.0 Scenario, the supply chain will go through changes, such as real-time visibility throughout the entirety of the supply chain, continuous collaboration between the stages of the chain, among other significant changes.  相似文献

The objective of the present study is to verify the flypaper effect of 476 Brazilian municipalities from 2005 to 2012, considering the new variables as instruments of grants. Political alignment, alignment of the party, and coalition of the mayor with the federal president and of the state governor were considered as instruments of grants. A municipal tax autonomy index was considered as a control variable, which represents the percentage of local taxes in the municipal total revenues. The results allow concluding that the flypaper effect exists in Brazilian municipalities and is intensified by the alignment of the representatives in the same way of theoretical literature (Hamilton 1983; Hines & Thaler 1995; Inman 2008) and previous empirical studies in Brazil. Moreover, evidences of higher flypaper effect were found in municipalities with low tax autonomy.  相似文献

In real life growth processes there is always an intrinsic finite response time. This means that these systems do not respond instantaneously so that the logistic modeling of such processes should be formally described by a delayed logistic equation. This poses enormous difficulties to their time evolution modeling as there are no analytical solutions to the delayed logistic equation. In this paper we show that by performing a conventional Verhulst logistic modeling of the corresponding time series data, associated with a fine-coarse analysis of the resulting residuals, we can disclose the underlying periodicities due to the finite time response effects.  相似文献
