Unbiased estimation of expected return using CAPM

Estimation of expected return is required for many financial decisions. For example, an estimate for cost of capital is required for capital budgeting and cost of equity estimates are needed for performance evaluation based on measures such as EVA. Estimates for expected return are often based on the Capital Asset Pricing Model (CAPM), which states that expected excess return (expected return minus the risk-free rate) is equal to the asset's sensitivity to the world market portfolio (β) times the risk premium on the “world market portfolio” (the market risk premium). Since the world market portfolio, by definition, contains all assets in the world, it is not observable. As a result, an estimate for expected return is commonly obtained by taking an estimate for β based on some index (as a proxy for the world market portfolio) and an estimate for the market risk premium based on a potentially different index and multiplying them together. In this paper, it is shown that this results in a biased estimate for expected return. This is undesirable since biased estimates lead to misallocation of funds and biased performance measures. It is also shown in this paper that the straightforward procedure suggested by Fama and MacBeth [J. Financ. Econ. 1 (1974) 43] results in an unbiased estimate for expected return. Further from the analysis done, it follows that, for an unbiased estimate, it does not matter what proxy is used, as long as it is used correctly an unbiased estimate for expected return results.     

Inflation dynamics in Kazakhstan1

In January 1992, Kazakhstan initiated a reform programme to move towards market-determined prices. The price liberalization process was characterized by large relative price shifts and an increase in the overall price level towards those observed in market economies. The paper shows how the piecemeal manner in which prices were liberalized resulted in strong relative price variability over a prolonged period of time, against a background of high inflation. Convergence towards international relative and absolute price levels has progressed but is not complete, with prices for energy and services in particular still below market economy levels.     

Self-Efficacy Toward Service, Civic Participation and the Business Student: Scale Development and Validation

This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students.     

Cultural agility and international assignees’ effectiveness in cross‐cultural interactions

While many mutable competencies and immutable personality traits have been shown to have a direct positive relationship with international assignee success, this study examines whether a set of situation‐specific cross‐cultural competencies comprising cultural agility are also related to international assignee success. This study examines whether the combination of three situation‐specific responses to cultural differences (cultural adaptation, cultural minimization and cultural integration) explain any additional variance in supervisor's ratings of international assignee success above and beyond personality and cross‐cultural competencies. To test this hypothesis, supervisor‐rated of assignees’ effectiveness in working with host nationals was regressed on the number of international assignees’ cultural orientations. Controlling for personality and dynamic competencies, the overall model was significant explaining 17 per cent of the total variance. This study provides some preliminary evidence on the importance of expatriates’ possessing the ability to possess concurrent cultural orientations. The HR practices to foster cultural agility are discussed.     

Back to the future. Is industry 4.0 a new tecno-organizational paradigm? Implications for Latin American countries

ABSTRACT

The objective of this article is to establish a dialogue between the recent ‘Industry 4.0’ (I4.0) literature and evolutionary neo-Schumpeterean studies about techno-organizational paradigms. In that direction, we wonder whether I4.0 constitutes a new paradigm, as it is assumed by the first group of literature, or it represents – until the moment – an intensification of key features of the information and communication technology (ICT) paradigm, following the second group of studies. Some questions are raised about the implications of I4.0 for developing countries (DEC), afterwards. Specifically, we reflect on the possibilities of these countries to identify and take advantage of new windows of opportunity, opened by the development and diffusion of these technologies. In this regard, the review of recent Latin American experience raises strong concerns regarding I4.0 as a new source of intra- and international heterogeneity, linked to the severe difficulties these countries have in appropriating these technologies in the form of productivity gains and quasi-rents. It seems that this is partially derived from weak technological, organizational, and connectivity capabilities paths of accumulation between institutions and actors.     

Who Uses Facts Up Front? A Baseline Examination of Who is Using Standardized Front‐of‐Package Nutrition Disclosures

The Facts Up Front front‐of‐package (FOP) nutrition system is currently displayed on packaged foods in the United States. This initiative is being implemented by more than 50 manufacturers, retailers, and wholesalers in the United States on their branded and private‐label packaged food products. The in‐store presence of Facts Up Front is supported by a recently launched consumer education campaign. This study employs a sample of 1,400 female primary household shoppers with children, with oversamples of Hispanic and African American ethnic subgroups, to examine initial awareness and evaluations of Facts Up Front. Results show that Hispanics are more aware of and engaged with Facts Up Front than Caucasians. African Americans report higher levels of engagement and understanding of Facts Up Front vs. Caucasians. Importantly, Hispanic and African American mothers also report using this FOP system to make decisions. Based on these findings, important implications are offered for consumer welfare and public policy.     

Design principles of hybrid approaches in new product development: a systematic literature review

Setting the right approach for new product development (NPD) in the presence of uncertainty remains an ongoing debate in innovation management. Stage-gate systems (SGS) and agile methodology (AM) are the dominant approaches. Recently, hybrid approaches (combining SGS and AM) have been proposed. Although these hybrid approaches represent a significant development in NPD, combining them without considering their design principles might lead to contradictory and competing conceptual formulations, thus increasing the difficulty of comparison among studies. Moreover, scholars and practitioners may struggle to understand when, why and how a certain configuration of the NPD process provides the right response to different manifestations of uncertainty. The current literature faces problems regarding the clarity of design principles (e.g. flexibility and adaptability), and this has led to research gaps concerning the uncertainty contingency and outcomes of hybrid approaches. This study combines bibliometric and content analyses to identify four design parameters and principles of NPD hybrid approaches: flexibility, adaptability, velocity and integration. Our findings might help advance the development and comparison of different hybrid approaches.
