Abstract

Purpose

The purpose of this paper is to present a case study in which data envelopment analysis (DEA) is used to evaluate and classify the suppliers of a Colombian motorcycle assembly company. This tool allows the integration of several attributes into single performance measures (cross-efficiency and diversity efficiency) and subsequent classification based on the values obtained for these two metrics.

Design/methodology/approach

The classification uses a methodology based on two main tools. The first is an input-oriented cross-efficiency DEA model with ordinal variables to evaluate the suppliers’ performance, and the second is a classification of these into categories that identifies those with good performance for features that make them outstanding.

Findings

The assembly company segments its suppliers according to supply frequency. The results show that suppliers working under a just-in-time system achieve superior performance with respect to other suppliers.

Practical implications

The application of this methodology in a real-world case illustrates how DEA can be a useful tool to support the evaluation and classification of suppliers (a process of increasing complexity given the current trend to include multiple strategic measures together with classical operational measures). Moreover, the methodology illustrated in the study can be adapted to other similar settings.

Originality/value

The main contributions of this paper are twofold. First, to the best of our knowledge, this is the first study to illustrate the use of DEA in a real case related to supplier evaluation. Second, the presence of ordinal variables (e.g. quality or environmental ratings) gives rise to DEA variants seldom used in this context.

Propósito

Este artículo presenta un caso de estudio en el que se utiliza análisis envolvente de datos (DEA) para evaluar y clasificar los proveedores de una ensambladora colombiana de motocicletas. Dicha herramienta permite integrar múltiples atributos en dos medidas de desempeño (eficiencia cruzada y de diversidad) y la posterior clasificación de éstos con base en los valores obtenidos para ambas medidas.

Diseño/metodología/enfoque

La clasificación usa una metodología basada en dos herramientas. La primera es un modelo DEA de eficiencia cruzada orientado a las entradas con variables ordinales que se usa para evaluar el desempeño de los proveedores. La segunda es una clasificación de los proveedores en categorías para identificar aquellos con buen desempeño en algunas características que los hacen sobresalientes.

Resultados

La compañía segmenta sus proveedores de acuerdo con la frecuencia de abastecimiento. Los resultados muestran que los proveedores que operan bajo justo a tiempo (Just-in-time, JIT) tienen un desempeño superior con respecto a los demás proveedores.

Implicaciones prácticas

La aplicación de esta metodología en un caso real ilustra como DEA es una herramienta útil para apoyar la evaluación y clasificación de proveedores (un proceso de complejidad creciente gracias a la tendencia actual de incluir medidas estratégicas junto a las medidas operacionales comúnmente utilizadas). Además, la metodología utilizada puede adaptarse fácilmente a otras situaciones similares.

Originalidad/valor

Las contribuciones de este artículo son dos. Primero, hasta donde sabemos, este es el primer estudio que ilustra el uso de DEA en un caso real de evaluación de proveedores. Segundo, la presencia de variables ordinales (por ejemplo, evaluaciones de calidad y medioambiente) resultan en modelos DEA que son poco utilizados en este contexto.

Abstract

Purpose

This article describes the findings of a phenomenological study whose purpose was to understand the essence of education from the analysis of the relationships emerging between the main educational actors (professors and students).

Design/methodology/approach

This research was approached from the qualitative paradigm and from a method of phenomenological analysis; specifically, heterological phenomenology is proposed, which is presented as the search for human relationships as a founding condition of education. For collecting information, a phenomenological interview with twelve professors from public and private universities in the city of Manizales (Colombia) was used.

Findings

The results reveal the experiences had in education from the relationships that have left their mark on the subjects and discover education as a relationship with the Other of welcome, hospitality, vocation and responsibility.

Originality/value

The originality of the study is in the particular method, heterological phenomenology, which investigates the experience of human relationships as a scenario for constructing a reality in which the starting point is the narrative that the Other (research subject) makes of his encounters with his-Other (subject present in the narrative).

This paper aims to analyse through a bibliometric study the academic literature that relates entrepreneurship to foods.

Abstract

Purpose

This paper aims to analyse through a bibliometric study the academic literature that relates entrepreneurship to foods.

Design/methodology/approach

A database of 1,300 papers published in the ISI Web of Science was generated. The bibliometric techniques allowed us to describe scientific literature evolution, most productive authors, institutions and countries, most relevant sources and documents, trend topics and social structure.

Findings

The results illustrate an upward trend, more accentuated in the last four years, in publishing papers relating entrepreneurship to the food industry.

Originality/value

This research is novel because although numerous articles relate the food industry to entrepreneurship, no bibliometric articles that analyse the scientific production that relates both terms have been found in the literature.

Abstract

Purpose

This paper aims to evaluate whether entrepreneurs with an innovative product/service are more likely to formally register their businesses. Understanding the decision of business registration as a rational choice of the entrepreneurs, where she weighs the costs versus the benefits of such formalization, the study expands the literature on informal entrepreneurship by looking at the benefit-side rather than the typically evaluated cost-side of an individual cost-benefit evaluation.

Design/methodology/approach

The authors relied on the Global Entrepreneurship Monitor (GEM) adult population survey to evaluate the hypothesis. Specifically, the authors used the GEM data of 2016 for Colombia, covering 2,069 observations (a representative sample at the country level), evaluating the relationship between innovativeness and business registration for the early stage of the entrepreneurial process. Given the nature of our dependent variable, the authors estimated a logistic regression model.

Findings

Different from what the authors hypothesized, they did not find empirical evidence for a positive correlation between an innovative product or service and business registration. Instead, businesses that compete with many others offering the same product/service have a higher tendency to register at the Chamber of Commerce. Contrarily of what might be suspected, opportunity-based entrepreneurship – as opposed to necessity-based – is not a relevant variable when formalizing a business, providing evidence for our hypothesis that necessity-based entrepreneurship cannot be equalized with informal entrepreneurship. Additionally, the authors show that an entrepreneur with higher socioeconomic status is more likely to register his company.

Research limitations/implications

The results provide first exploratory evidence that the benefit evaluation may play a role in formalizing a start-up, thus calling for future research that not only tackles the influence of registration costs and administrative burden but rather looks at the outcome of a cost-benefit analysis. The data imply several limitations which future research should address: variables measuring the innovativeness of the product/service are rather coarse measures and need to be expanded and detailed in future research. Additionally, the authors acknowledge that a relatively high number of missing values may generate a selection bias in our population sample. Finally, because of situating the research in a developing country, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further.

Practical implications

In a country like Colombia with very high levels of informality, it is necessary that the government fully understands the role of innovation in the formalization process of start-ups. The results indicate that a differentiation of support mechanisms to increase the formalization of businesses according to the different stages of their development may be necessary and that aside from costs, benefits of formalization play a role. A higher level of formality is not only related to economic growth but also much better protection of workers, therefore going beyond the reduction of registration costs and the implied administrative burden should be an additional public policy target for decreasing informality. Finally, the correlation of socioeconomic stratum with the decision to register hints at a varying evaluation of formalization, a point that merits attention by government and academia.

Originality/value

The study shifts the focus from the evaluation of solely costs for business registering as a barrier to start-up formalization to the cost-benefit analysis. The authors propose – and show – that such an evaluation is not generalizable for all kinds of business. Specifically, the authors show that a start-up is more likely to register when it competes with a large number of competitors than when it competes with a smaller number of others offering the same. At the same time, the authors also show that the stage at which the start-up company is at influences the decision to formalize.

Propósito

Este trabajo tiene como objetivo evaluar si los empresarios con un producto/servicio innovador son más propensos a registrar formalmente sus negocios, entendiendo la decisión de registrar el negocio como una elección racional, en la que el emprendedor sopesa los costos frente a los beneficios de dicha formalización. Este estudio amplía la literatura sobre el emprendimiento informal al plantear un análisis enfocado en los beneficios de una formalización del negocio.

Diseño/metodología/enfoque

Se utiliza la encuesta Global Entrepreneurship Monitor (GEM) Adult Population Survey para evaluar nuestras hipótesis. Específicamente, utilizamos los datos del GEM de 2016 para Colombia, cubriendo 2.069 observaciones (una muestra representativa a nivel de país), evaluando la relación entre una oferta innovadora y el registro de negocios para la etapa temprana del proceso emprendedor. Dada la naturaleza de nuestra variable dependiente, estimamos un modelo de regresión logística.

Conclusiones

Contrario a la hipótesis propuesta, no encontramos una correlación estadísticamente significativa positiva entre un producto o servicio innovador y el registro de empresas. En su lugar, las empresas que compiten con muchas otras empresas que ofrecen el mismo producto/servicio tienen una mayor tendencia a registrarse en la Cámara de Comercio. Asimismo, el emprendimiento basado en la oportunidad -en contraposición al basado en la necesidad- no es una variable relevante a la hora de formalizar un negocio, hallazgo en congruencia con a nuestra hipótesis de que el emprendimiento basado en la necesidad no puede equipararse al emprendimiento informal. Además, mostramos que un emprendedor con un estatus socioeconómico más alto tiene una mayor probabilidad de registrar su empresa.

Limitaciones/implicaciones de la investigación

Los resultados obtenidos proporcionan la primera evidencia exploratoria de que la evaluación de los beneficios puede desempeñar un rol en la formalización de una empresa de nueva creación, por lo que se requiere mayor investigación que no sólo aborde la influencia de los costos de registro y administrativos asociados, sino que examine el resultado de un análisis costo-beneficio. Los datos utilizados tienen varias limitaciones que una investigación posterior debería abordar: las variables que miden el carácter innovador del producto/servicio son medidas muy básicas y deben ampliarse y detallarse en futuros estudios. Además, el número relativamente alto de valores perdidos puede generar un sesgo de selección en nuestra muestra empleada. Por último, al situar nuestra investigación en el contexto de un país de desarrollo, los resultados pueden ser poco generalizables. Por lo tanto, futuras investigaciones deberían abordar en detalle los hallazgos presentados.

Implicaciones prácticas y sociales

En un país como Colombia, con niveles muy altos de informalidad, es necesario que el gobierno comprenda plenamente el papel de la innovación en el proceso de formalización de las empresas emergentes. Nuestros resultados indican que una diferenciación de los mecanismos de apoyo para aumentar la formalización de las empresas según las diferentes etapas de su desarrollo puede ser necesario. A su vez, además de los costos, los beneficios de la formalización juegan un papel importante. Un mayor nivel de formalidad no sólo está relacionado con el crecimiento económico sino también con una mejor protección de los trabajadores, por lo que ir más allá de la reducción de los costos de registro y de la carga administrativa implícita debería ser un objetivo adicional de política pública para disminuir la informalidad. Por último, la correlación del estrato socioeconómico con la decisión de registrarse sugiere que la evaluación de formalizarse varía dependiendo del estatus socioeconómico, un punto que merece la atención del gobierno y la academia.

Originalidad/valor

Nuestro estudio desplaza la atención exclusiva en los costos de registro de una empresa, y sus barreras asociadas, hacia el análisis costo-beneficio como parte de la evaluación y decisión de formalización de las nuevas empresas. Proponemos ‐y demostramos‐ que dicha evaluación no es generalizable para todo tipo de empresas. En concreto, demostramos que es más probable que una empresa emergente se registre cuando compite con un gran número de competidores que cuando compite con un número menor de otras que ofrecen lo mismo. A su vez, también mostramos que la etapa de desarrollo en la cual se encuentra la empresa emergente influye en la decisión de formalizarse.

Abstract

Purpose

The purpose of this paper is to focus on the impact of trade openness and technology import on the change in demand structure of employment toward skilled workers. Because of the limited number of empirical papers done in the case of Tunisia, this research investigates whether these factors had similar effects on relative labor demand in Tunisia to those observed in the international literature.

Design/methodology/approach

For this purpose, the paper uses a manufacturing industries database provided by the Tunisian National Institute, the Quantitative Economic Institute and Comtrade of United Nations for six manufacturing industries. The methodology used here is a panel data technique, and consists of estimating a dynamic relative employment equation.

Findings

Empirical results show that trade liberalization and technology change positively affect relative employment of Tunisian manufacturing industries which confirms the existence of skill biased technological change that contributes to increase the relative demand for skilled workers.

Originality/value

The paper adds to existing literature by studying for the first time the case of Tunisian manufacturing industries by using dynamic model. The paper deals also with an econometrics issues related to the use of suitable estimation methodology in the case of dynamic panel data at macroeconomics level.
