Educational Marketing in the Latin American Context: An Executive MBA Case

ABSTRACT

This paper provides Latin American Executive MBA students' approaches to studying, achieving profile, preferences and perceptions of instructional methods used in teaching marketing courses and educational marketing segments based on their preference ranking of instructional methods and approaches to studying. Results indicate that, in general, these students have a strong need for excellence, and for gaining status with experts. Their approach to studying is directed first at understanding what they learn, and then at doing well in their courses. Results also indicate that such students strongly prefer courses using participative instructional methods, such as case studies, to the instructor-dominated lecture method. Thus, there appears to be a gap between the types of instructional methods now being emphasized in MBA classrooms and the methods preferred by the students. These students can be placed into four distinct segments, namely Technology Sophisticated Learners, Academic Success Seekers, Degree Seekers and Instructor-Oriented Learners. Managerial implications from the results are drawn both for the administrators and for the faculty members teaching in an EMBA program.

RESUMEN. Este estudio ilustra el enfoque do los estudiantes latinoamericanos de MBA Ejecutivo sobre las materias de estudio, trazado de un perfil, preferencias y percepción de los métodos de enseñanza utilizados en los cursos de mercadeo y mereadeo educacional en base a sus preferencias, que se utilizaron para desarrollar un sistema de clasificación de los métodos y enfoques de la enseñanza y el aprendizaje. De acuerdo a los resultados, los estudiantes sienten una gran necesidad de alcanzar la exceleneia, y de adquirir renombre junto a los expertos. Ellos encaran sus estudios eonsiderando prioritaria la función de comprender lo que aprenden, y tienen como meta secundaria el obtener buenos resultados en sus cursos. Además, los resultados también indican que estos esludiantes prefieren claramente usar métodos de enseñanza participativos–tales como los estudios de caso–al método disertivo dominado por el profesor. Consecuentemente, nos parece que existe una brecha entre los métodos de enseñanza que se están implementando en las salas de aulas de los cursos de los MBA, y los métodos preferidos por los alumnos. Estos estudiantes pueden dividirse perfectamente en cuatro segmentos, o sea, Estudiantes de Tecnologías Sofisticadas, Buscadores de éxito Académico, Buscadores de Diplomas y Estudiantes Orientados por el Instructor. En el estudio trazamos las implicancias administrativas inherentes a estos resultados, así como para los docentes que están enseñando el programa EMBA.

RESUMO. Este trabalho apresenta a visão de estudantes do MBA Executivo da América Latina, em relação ao estudo, à formação do seu perfil, às preferências e às percepções dos métodos didáticos utilizados nos cursos de marketing e nos segmentos educacionais dc marketing, baseados no ranking de suas preferências pelos métodos didáticos e pelas abordagens do estudo. Os resultados indicam que, em geral, estes estudantes buscam rigorosamente a excelência e a conquista de status através de especialistas. A sua abordagem do estudo está direcionada. primeiramente, ao conhecimento e, em segundo lugar, ao sucesso do seu desempenho. Os resultados também indicam que tais estudantcs preferem nitidamente os cursos que utilizam o método didático participativo, como o estudo de casos, ao método de ensino tradicional expositive Assim. parece haver uma lacuna entre os tipos de métodos didáticos atualmente sendo enfatizados nas aulas de MBA e entre os métodos preferidos pelos estudantes. Estes alunos podem ser classificados em quatro segmentos distintos: Aprendizes da Alta Tecnologia, Perseguidores do Sucesso Acadêmico, Perseguidores de Títulos e Aprendizes Orientados por Instrutor. As implicações gerenciais, a partir dos resultados, são delineadas tanto para os administradores quanto para os membros do corpo docente que ensinam no programa de MBA Executivo.

On dynamic selection of households for direct marketing based on Markov chain models with memory

A simple, dynamic selection procedure is proposed, based on conditional, expected profits using Markov chain models with memory. The method is easy to apply, only frequencies and mean values have to be calculated or estimated. The method is empirically illustrated using a data set from a charitable foundation. The results reveal some interesting features with respect to the time-dependent behavior of certain subsets of households, whereas the profitability increases by about 9% by using the method compared to a benchmark of sending a mailing to all households.     

Foreign Direct Investment and the External Wealth of Nations: How Important Is Valuation?

While the balance sheet approach has increased the focus on position data, differences in valuation practices for foreign direct investment (FDI) make cross‐country comparisons difficult. To enhance comparability, the IMF's Balance of Payments and International Investment Position Manual, sixth edition, which some countries have already implemented and others will implement in the coming years, recommends seven methods for valuation of unlisted FDI. This paper demonstrates that both the valuation method and simple differences in estimation techniques can fundamentally change a country's financial balance sheet. Using Denmark as an illustration, unlisted FDI equity liabilities vary from 22 to 156 percent of GDP when applying different estimation techniques, but just one valuation method, price to earnings. These measurement uncertainties can lead to important misunderstandings and affect policy recommendations, thus pointing to the need for further international harmonization. While the results are presented in an FDI context, the uncertainties also apply to other macroeconomic datasets, including national accounts statistics.     

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.

The Response to the Commitment with Block-Leader Recycling Promotion Technique: A Longitudinal Approach

SUMMARY

This article focuses on the study of the changes in consumers' recycling beliefs, attitudes, and behavior due to the application of one promotion technique: a commitment by block leader technique characterized by the agreeing participant signing a request or statement in which s/he makes a commitment to recycle as a result of the encouragement of a person who belongs to the same social circle. We therefore carried out a quasi-experimental work whose results enable us to explain the response to this recycling promotion technique. It makes a contribution to existing environmental literature by (1) systemizing the set of existing doctrines in order to explain the response to this recycling promotion technique, and (2) revealing the effects of this technique on people's beliefs and attitudes. The practical implications that may stem from these contributions are of an educational nature and should be of use to the public management of promotion campaigns.

Optimal high-frequency trading with limit and market orders

We propose a framework for studying optimal market-making policies in a limit order book (LOB). The bid–ask spread of the LOB is modeled by a tick-valued continuous-time Markov chain. We consider a small agent who continuously submits limit buy/sell orders at best bid/ask quotes, and may also set limit orders at best bid (resp. ask) plus (resp. minus) a tick for obtaining execution order priority, which is a crucial issue in high-frequency trading. The agent faces an execution risk since her limit orders are executed only when they meet counterpart market orders. She is also subject to inventory risk due to price volatility when holding the risky asset. The agent can then also choose to trade with market orders, and therefore obtain immediate execution, but at a less favorable price. The objective of the market maker is to maximize her expected utility from revenue over a short-term horizon by a trade-off between limit and market orders, while controlling her inventory position. This is formulated as a mixed regime switching regular/impulse control problem that we characterize in terms of a quasi-variational system by dynamic programming methods. Calibration procedures are derived for estimating the transition matrix and intensity parameters for the spread and for Cox processes modelling the execution of limit orders. We provide an explicit backward splitting scheme for solving the problem and show how it can be reduced to a system of simple equations involving only the inventory and spread variables. Several computational tests are performed both on simulated and real data, and illustrate the impact and profit when considering execution priority in limit orders and market orders.     

THE BLACK-SCHOLES EQUATION REVISITED: ASYMPTOTIC EXPANSIONS AND SINGULAR PERTURBATIONS

In this paper, novel singular perturbation techniques are applied to price European, American, and barrier options. Employment of these methods leads to a significant simplification of the problem in all cases, by reducing the number of parameters. For American options, the valuation problem is reduced to a procedure that may be performed on a rudimentary handheld calculator. The method also sheds light on the evolution of option prices for all of the cases considered, the results being particularly illuminating for American and barrier options.
