Institutional Portfolios: Diversification through Farmland Investment

This article demonstrates that farmland can enhance the overall performance of institutional portfolios which are currently dominated by stocks, bonds, and business real estate. Unlike previous articles on farmland returns, this article addresses the issue of "smoothing bias" associated with appraisal-based farmland returns. Improved measures of income returns to farmland are also used in developing the estimates of optimal portfolios. Parametric testing revealed that farmland continues to enter the optimal portfolios even for large increases in the variance or for large reductions in the annual returns to farmland.     

Simplified Risk Analysis in Agricultural Extension

Attention is given to the major methods of assessing risk in order to make choices. The literature frequently reports studies on mean-variance (E-V) analysis and stochastic dominance rules. Both of these methods are compared, in an agricultural application, with the approach outlined by Hanoch and Levy. The empirical results suggests that Hanoch and Levy's criterion appear to reduce the size of the risk-efficient set, and that the sets of recommendations from the methods under comparison were consistent. The two recommendations generated by Hanoch and Levy's rule were found to be reasonable for this particular decision process.

Value-at-Risk computation by Fourier inversion with explicit error bounds

The Value-at-Risk of a delta–gamma approximated derivatives portfolio can be computed by numerical integration of the characteristic function. However, while the choice of parameters in any numerical integration scheme is paramount, in practice it often relies on ad hoc procedures of trial and error. For normal and multivariate t-distributed risk factors, we show how to calculate the necessary parameters for one particular integration scheme as a function of the data (the distribution of risk factors, and delta and gamma) in order to satisfy a given error tolerance. This allows for implementation in a fully automated risk management system. We also demonstrate in simulations that the method is significantly faster than the Monte Carlo method, for a given error tolerance.     

Relating the Zone of Tolerance to Service Failure in the Hospitality Industry

The purpose of this study was to explore the zone of tolerance concept in relation to perceptions of service encounters, specifically when service failures are likely to occur. A simulated restaurant experience consisting of a series of dining service encounters was conducted with a sample of academic staff and research students. Results showed that individuals have different perceptions with different variability in their zone of tolerance; individuals appear to have a larger zone of tolerance when dealing with negative encounters and a narrower zone of tolerance for positive encounters. In addition, an initial negative encounter predisposes customers to future negative encounters. Failure is seen as a difficult concept to judge as individuals have diverse perceptions of what constitutes a failure and when it starts. Further research directions are proposed.

The IASB's Discussion Paper on the Conceptual Framework for Financial Reporting: A Commentary and Research Review

Consistent with the mission of the International Association for Accounting Education and Research (IAAER) to “promote global excellence in accounting education and research, and to maximize accounting academics' contribution to the development and maintenance of high‐quality, globally recognized standards of accounting practice,” this paper provides a commentary and research review by an ad hoc committee of the IAAER on the IASB's Discussion Paper DP/2013/1—A Review of the Conceptual Framework for Financial Reporting. The comments focus on four main areas about which prior academic research can inform standard setters in their consideration of the revised Conceptual Framework: (1) recognition and derecognition, (2) measurement, (3) presentation and disclosure, and (4) other comprehensive income. The views expressed here by the ad hoc committee are those of the authors and do not necessarily reflect a consensus view of the IAAER membership or its Executive Committee. The paper supports the IASB's general objective of developing one set of globally acceptable accounting standards based on a cohesive and complete Conceptual Framework.     

Dynamic market entry and the value of flexibility in transitional international joint ventures

The purpose of this study is to formalize the optimal choice of market entry strategy for an individual multinational enterprise (MNE) from a dynamic perspective. It is argued that incorporating a suitable treatment of irreversibility, uncertainty and flexibility related to an MNE's investment decision gives further insights into the expansion, dissolvement, and optimal timing of international joint ventures (IJVs). In most cases, the initial entry strategy serves as a platform allowing the firm to make subsequent investments to exploit host-country advantages and capabilities. We allow for this by taking a three-step expansion strategy explicitly into account. The evolutionary process of the value of the foreign direct investment can be interpreted as a compound complex chooser option. The results suggest that uncertainty, size of equity share and future investment/divestment opportunities play an important role when it comes to transit from export to the first phase of the foreign direct investment commitment. The paper underscores the importance of modeling the dynamics of market entry and helps to refine the application of real options in the alliance context by providing a closed-form solution in continuous time to value the overall strategic flexibility.
