Empirical evidence of the existence of speculative bubbles in the prices of stocks traded on the São Paulo Stock Exchange

Speculative price bubbles are defined as a significant deviation between an asset's intrinsic value and its market value and in this paper it refers to stock values. Literature about the theme has noted the existence of bubbles in various types of markets and their respective assets. A great deal of effort has been directed toward identifying bubbles in stock price indices. However, few research endeavors focus on assets as the unit of analysis. Studies about stocks in Brazil have identified the presence of bubbles in IBOVESPA (São Paulo Stock Exchange Index). Given this context and assuming that the speculative bubbles are present in the Brazilian stock market, this research is focused on the following question: Is there evidence of the existence of speculative bubbles in stock prices traded on the São Paulo Stock Exchange? Econometric tests were performed on twenty-seven stocks, based upon their positions each semester, for the period between the first semesters of 1990 until the first semester of 2010. The nominal values of the selected stocks were adjusted for inflation by the IPCA (Brazilian Consumer Price Index). In order to identify the presence of bubbles, we applied the Johansen non-cointegration test and/or the Granger non-causality test between the intrinsic value, dividends and interest on equity capital, and the market value (semester closing price) of the stocks. The primary findings reveal a presence of bubbles in twenty of the twenty-seven stocks, at a 5% significance level. Of the seven stocks not showing evidence of bubbles, six are financial institutions. In five stocks the tests reveal Granger causality stemming from the market value toward the intrinsic value. The study findings are consistent and contribute with previous research in the literature and, are useful for investors, financial institutions, academics, government agents, and traders.     

Can Agile Project Management Be Adopted by Industries Other than Software Development?

This research paper presents evidence from an exploratory survey on the use of agile project management (APM) practices and the presence of APM enablers in 19 medium‐ and large‐sized companies from different industry sectors considering innovative projects. The results show that these companies are possibly struggling to use their current management practices in the face of different project challenges. Additionally, the presence of some APM enablers indicates opportunities to adapt the APM theory for different companies other than those in software development. Future research should explore the correlation between APM practices and enablers in order to develop “hybrid” management models for different industries.     

Demographic product segmentation in financial services products in Australia and New Zealand

Segmentation and targeting are cited as being a core part of marketing strategy for any organisation. While there has been much written on brand segmentation, product segmentation research has not been common. This paper examines whether different types of customers buy different banking products. A sample of 52,000 Australian households and 12,000 in New Zealand from the Roy Morgan Single Source Survey was utilised to profile users of different banking products on offer. The results indicated that there is some segmentation or partitions evident in a limited number of banking products; for the most part there was little difference in customer profile across comparable products offered by Australian and New Zealand banks.     

‘We Are Here Alone’: The Ironic Potentials and Vulnerabilities of Mixed (Up) Districts in Central Jakarta

The durability of central city districts in large metropolitan systems of the majority world has largely been attained through intricate intersections of physical, infrastructural, human and discursive materials, as these intersections are continuously remade through shifting constellations of the incremental initiatives of residents. Residents have learned to use the city as a place to continuously explore new relationships among things and extract a wide range of unanticipated capacities from them. This is a collective resourcefulness from which there might be much to draw in terms of using the carbon‐driven exigencies of infrastructural transformation as the occasion to reanimate more egalitarian political projects. Although many collective efforts are increasingly being disassembled, the reflections of a single resident of one of Jakarta's most heterogeneous residential districts points to how the revitalization of such efforts might be conceived. The efficacy of political efforts to address intensified vulnerability partly entails replenishing intense mixtures of built and physical environments as provocations and platforms for complex social maneuvers.     

Green Product Development and Product Portfolio Management: Empirical Evidence from an Emerging Economy

Few studies have explored the relationship between green products development (GPD) and product portfolio management (PPM). When considering evidence from emerging economies, the knowledge gap is even deeper. Consequently, the objective of this work is to analyze how green and traditional practices of new product development (NPD) influence product portfolio and NPD performance. In addition, we explore how GPD opens new markets and technology opportunities. The empirical evidence is based on a sample of firms that are developing products and belong to innovative industrial sectors in Brazil. In general, the framework developed and tested in this research indicates the following: (i) the adoption of GPD practices significantly influences product portfolio performance; (ii) the adoption of GPD practices tends to generate positive results with regard to obtaining technological and market opportunities; (iii) the adoption of traditional PPM practices influences the dependent factors. Unexpectedly, correlations between a firm's size or age and its performance were not confirmed. This is the first empirical evidence relating GPD, PPM, and market and technology opportunities in Brazil. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Defining the Content of Sustainability Reports in Nonprofit Organizations: Do Stakeholders Really Matter?

The aim of the article is to investigate the role of stakeholder engagement and participation in nonprofit organizations’ sustainability reporting, according to the literature on third sector and stakeholder theory. To verify the levels of involvement, the authors conducted an empirical survey, using content analysis, on a sample of 54 sustainability reports of nonprofit organizations included in the Global Reporting Initiative database as of September 1, 2012. In order to strengthen the results obtained from the content analysis, the authors shared their findings with the organizations of the sample. The survey showed that there were some criticisms regarding stakeholder participation in the targeted research field. These are considered in the conclusions. Questions for the future included whether stakeholder engagement is moving from being simply a way to consult and influence stakeholders to being an effective instrument for involving them in nonprofit organizations’ reporting and decision-making processes, through mutual commitment.
