Delivery horizon and grain market volatility

We study the difference in the volatility dynamics of CBOT corn, soybeans, and oats futures prices across different delivery horizons via a smoothed Bayesian estimator. We find that futures price volatilities in these markets are affected by inventories, time to delivery, and the crop progress period and that there are important differences in the effects across delivery horizons. We also find that price volatility is higher before the harvest starts in most cases compared to the volatility during the planting period. These results have implications for hedging, options pricing, and the setting of margin requirements. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 30:846–873, 2010     

What is a strategic acquisition? Decision modeling in support of foreclosed housing redevelopment

This paper describes and develops a model for calculating location-based strategic values of foreclosed properties considered for acquisition and redevelopment by community development corporations (CDCs). A property’s strategic value refers to its proximity to site-specific neighborhood amenities and disamenities (e.g. schools, public transit, distressed properties), given the relative importance of that proximity to CDC organizational and community objectives. We operationalize the concept of strategic value, and apply this concept to a salient public sector decision problem. Using data and value assessments from a CDC engaged in foreclosed housing redevelopment, we compute measures of strategic value for a set of acquisition candidates. We show that strategic values can differ in systematic ways depending on the types of amenities and disamenities identified as relevant for CDC acquisition decisions, the relative importance assigned to those amenities and disamenities, and the utility maximization objectives of the CDC. We conclude by proposing a multi-criteria decision model for foreclosed housing acquisition and redevelopment which incorporates a theory of residential housing impacts for which strategic value measures are a special case.     

Global compliance with international accounting education guidelines

The International Accounting Education Guidelines (IAEG) of the International Federation of Accountants (IFAC) issued since 1982 specify the components for the Professional preparation to become a qualified accountant.

This paper presents the results of a survey of compliance conducted in fifty-four countries outside the USA with International Accounting Education Guidelines (IAEG), as issued by the International Federation of Accountants (IFAC). Its purpose is to provide a benchmark measure of compliance for current assessment of accounting education, and for reference in future studies. This study is the first attempt to examine compliance with IAEGs in all sectors of the world in which IFAC has members. The paper is divided into the following sections: international accounting education guidelines; survey questions; methodology; results; effectiveness of the guidelines, and summary and conclusions.     

Using uncensored communication channels to divert spam traffic

We analyze a simple, feasible improvement to the current email system using an uncensored (open) communication channel. Such a channel could be an email folder or account, to which properly tagged commercial solicitations are routed without filtering along the way. We characterize the circumstances under which senders would voluntarily move much of their spam into the open channel, leaving the traditional email channel dominated by person-to-person mail. We then show that under certain conditions all email recipients are better off when an open channel is introduced. Only recipients wanting spam will use the open channel enjoying the less disguised messages and cheaper sale prices, and for all recipients the dissatisfaction associated with both undesirable mail received and desirable mail filtered out decreases.     

Estimating panel data models in the presence of endogeneity and selection

We consider estimation of panel data models with sample selection when the equation of interest contains endogenous explanatory variables as well as unobserved heterogeneity. Assuming that appropriate instruments are available, we propose several tests for selection bias and two estimation procedures that correct for selection in the presence of endogenous regressors. The tests are based on the fixed effects two-stage least squares estimator, thereby permitting arbitrary correlation between unobserved heterogeneity and explanatory variables. The first correction procedure is parametric and is valid under the assumption that the errors in the selection equation are normally distributed. The second procedure estimates the model parameters semiparametrically using series estimators. In the proposed testing and correction procedures, the error terms may be heterogeneously distributed and serially dependent in both selection and primary equations. Because these methods allow for a rather flexible structure of the error variance and do not impose any nonstandard assumptions on the conditional distributions of explanatory variables, they provide a useful alternative to the existing approaches presented in the literature.     

Taxes and production: The case of Pakistan

This paper investigates the effectiveness of investment incentives and corporate income taxes in influencing production and investment decisions in the Pakistani wearing apparel and leather products industries. Three tax instruments are considered: the corporate income tax (CIT), the investment tax credit (ITC), and the capital cost allowance (CCA).The results show that since there are significant capital adjustment costs, it is important to distinguish between the short, intermediate, and long-run effects associated with the tax instruments. Production decisions are relatively more responsive to changes in the ITC rate compared to changes in either CCA or CIT rates in each run. However, only in the long run for the apparel industry are the ITC and CCA rates cost effective in stimulating investment. The CIT is never cost effective. Thus targeted instruments outperform the general CIT instrument. In addition, although the incentive to invest is enhanced, there is little effect on output. Therefore, tax incentives essentially make production techniques more capital intensive.     

The Law of Demand versus Diminishing Marginal Utility

Diminishing marginal utility (DMU) is neither necessary nor sufficient for downward-sloping demand. Yet, upper-division undergraduate and beginning graduate students often presume otherwise. This paper provides two simple counter-examples that can be used to help students understand that the Law of Demand does not depend on DMU. The examples are accompanied with the geometry and basic mathematics of the utility functions and the implied ordinary/Marshallian demands.     

Integrated Market-Immersion Approach To Teaching New Product Development In Technologically-Oriented Teams

This article presents a market immersion methodology for teaching NPD in technologically-oriented teams. This methodology was developed during the early 1990s at the Lally School of Management and Technology of Rensselaer Polytechnic Institute. Since then, it has been successfully utilized to train in excess of one hundred MBA-level student teams. The NPD course is taught by a 5-member cross-functional team of faculty with backgrounds in marketing, manufacturing operations, and accounting. The course is modeled on Cooper's stage gate process, and the course is designed to provide a combination of classroom and apprenticeship experiences. The 6-credit, year-long course requires students to work in self-directed teams of approximately 5 to 6 members. Each student team chooses its own industry or technology domain in which to concentrate its efforts, and students undertake intensive market and field research in order to assess any existing market opportunities. Once a specific target market and market need have been identified, students are then required to design a product and an organization to meet that need. In specific, students must produce a detailed marketing, manufacturing, operations, advertising, distribution, and financial plan that can bring their product to market. During the process, students create multiple potential product designs, build mock-ups of their products, and field test the mock-ups. At every phase of the course, the teams are continuously immersed in real customer markets. As a result, teams must struggle to incorporate new market information and learning into their project in a consistent and holistic manner. The following article presents the curriculum content and tools, lessons learned, and student reactions to this original pedagogical approach to teaching NPD. Due to the length of the course, particular attention is paid to the teaming issues that naturally arise when teams work together on long-run projects. © 2002 Elsevier Science Inc.
