Se estudian los determinantes y la evolución de la actividad bursátil mensual en el mercado accionario colombiano de 2007 a 2016.

Para ello se emplean modelos de series de tiempo tipo ARIMAX y GARCH, incluyendo variables exógenas, recomendadas por la literatura previa.

Encontramos que la actividad bursátil puede ser pronosticada en buena parte por el valor rezagado a un mes y las innovaciones de cinco y 12 meses. También contribuyen a predecirla, como variables exógenas, una dummy de rendimientos positivos en los últimos tres meses, la presencia de emisiones primarias y el índice VIX de volatilidad del SP500. Estos resultados se mantienen en un alto grado al emplear medidas alternativas de actividad bursátil, el número total de operaciones y la rotación.

Se propone un modelo de predicción de la actividad bursátil que puede servir de modelo para otros mercados accionarios de Latinoamérica. El modelo obtenido es altamente predictivo del valor transado total del mercado al siguiente mes. La estimación de la actividad bursátil es de utilidad para instituciones como la Bolsa de Valores de Colombia, reguladores de los mercados financieros, así como para grandes inversionistas institucionales.

El propósito central de los mercados financieros secundarios consiste en facilitar la transacción de activos financieros, lo que debe reflejarse en alta actividad bursátil, tanto en número de operaciones como en valor transado total. La posibilidad de transar altos montos es una medida importante del desarrollo de un mercado financiero. De esta manera, el modelo aquí propuesto puede usarse para monitorizar y explicar el desarrollo del mercado. En particular, se evidencia el nocivo efecto de la debacle de Interbolsa a finales de 2012 y el positivo efecto de las emisiones primarias.

Este es el primer paper en estudiar la actividad bursátil del mercado accionario colombiano en años recientes. Sirve como modelo para el estudio y seguimiento de esta variable en otros mercados accionarios latinoamericanos.

To study the determinants and evolution of the trading activity in the Colombian Stock Market from 2007 to 2016.

ARMA time series models were used, including several explanatory variables recommended by previous literature.

We find that stock market activity can be predicted to a large extent by its lags, and that positive returns in the last three months, emissions and the VIX index are also explicative variables, as suggested by empirical studies in other countries and theoretical models of market microstructure. These results are robust by using alternative measures of trading activity, total number of trades and turnover.

The main contribution of this study is the analysis of the trading activity of the Colombian Stock Market, a critical variable for monitoring the development of any financial market.

This paper aims to review, systematize and integrate existing research on disposition effect and investments. This study conducts bibliometric analysis, including performance analysis and science mapping and thematic analysis of studies on disposition effect.

This study adopted a thematic and bibliometric analysis of the papers related to the disposition effect. A total of 231 papers published from 1971 to 2021 were retrieved from the Scopus database for the study, and bibliometric analysis and thematic analysis were performed.

This study’s findings demonstrate that research on the disposition effect is interdisciplinary and influences the research in the domain of both corporate and behavioral finance. This review indicates limited research on cross-country data. This study indicates a strong presence of work on investor psychology and behavioral finance when it comes to the disposition effect. The findings of thematic analysis further highlight that most of the research has focused on prospect theory, trading strategies and a few cognitive and emotional biases.

The findings of this study can be used by investors to minimize their biases and losses. The study also highlights new techniques in machine learning and neurosciences, which can help investment firms better understand their clients’ behavior. Policymakers can use the study’s findings to nudge investors’ behavior, focusing on minimizing the effects of the disposition effect.

This study has performed the quantitative bibliometric and thematic analysis of existing studies on the disposition effect and identified areas of future research on the phenomenon of disposition effect in investments.

Virtually all parents want their children to succeed academically. How to achieve this goal, though, is far from clear. Specifically, the temporal spacing between adjacent births has been shown to affect educational outcomes. While many of these studies have produced substantial and statistically significant results, these results have been relatively narrow in their application due to data limitations. Using Colorado birth certificates matched to schooling outcomes, we investigate the relationship between birth spacing and educational attainment. We instrument birth spacing with a previous pregnancy that did not result in a live birth. We find no overall effect of spacing on either the first or second children’s grade 3–10 test scores. Stratifying by the sexes of the children, we find that when the first child is a boy and the second a girl, an extra year of spacing increases the first child’s math, reading, and writing test scores by 0.07–0.08 SD, while there is no impact on the second child. This is the first study to do such an analysis using matched large-scale birth and elementary to high school administrative data, and to leverage a very large dataset to stratify our results by the sexes of the children.

This study investigates the level of variance in the real time demand for bagged cement, induced in response to the climatic sequence of the humid tropics, to support best practice calls for a weather-responsive supply chain strategy.

Data on the consumption of cement and site works for 100 ongoing building construction sites were gathered for a period of 12 months. The variance partitioning capabilities of the Ordinary Least Squares and Hierarchical Linear Modelling forms of regression analysis are comparatively used to evaluate the sensitivity of cement demand to the meteorological profile of wet-humid climate

The study outcome provides statistical evidence demonstrating that the meteorological profile of wet-humid climate induces a significantly high percentage of the variance in the real-time demand for bagged cement on construction sites. However, nested within this variance, are the fixed effects of the cement footprint of the building architecture inherent in the locality. Particularly, positive changes to reduce the wet trade composition of buildings or compensating changes in technological bias, are necessary to combat weather interference in the humid tropics.

The findings are exploratory, and not for the purposes of holistically forecasting cement demand, and can therefore only form part of a more comprehensive decision support system, bespoke to the study area.

The study outcome provides a back-end view to climatic adaptation in wet humid settings, making a compelling case for localized climate-risk adaptive supply chain strategies and policies geared towards sustainability in cement usage.

The study delineates the confounding impact of weather, distinct from local building architecture and technological bias, thus creating a methodological platform for replication and comparative productivity studies in diverse geographical areas.

The purpose of this article is to investigate whether the corporate social responsibility (CSR) and innovation activity of Certified B Corps® is comparable to listed companies in the Italian fashion industry.

The study includes a systematic literature review performed on Scopus® and combining keywords related to CSR and the fashion industry. Moreover, the literature review involves empirical analyses performed using a mixed-methods approach. First, a text-based content analysis was carried out on the companies' sustainability reports using the keyword scoring approach. The innovation index was then calculated, and multiple ordinary least squares (OLS) linear regressions were performed.

Based on the data available, it has emerged that Certified B Corps® who pursue a more significant number of SDGs are more likely to implement circular economy principles. Moreover, Certified B Corps® that have higher transparency standards and assume social responsibility practices also have higher innovation activity; in contrast, companies who used CSR only as a marketing tool have lower activity.

The analyses were influenced by the coronavirus disease 2019 (COVID-19) pandemic, revealing weaker relationships between the variables, as the analyses involved 2020 data. Furthermore, although the analysis considers the entire population of Certified B Corps® and listed companies in the Italian fashion industry, the size of the sample analyzed influenced the results and insights. Therefore, the analysis does not allow for generalizability. Finally, the study was conducted on a single country whose economic and social contexts have influenced some variables.

The paper highlights some managerial implications. Managers should consider CSR to be an investment and an opportunity to survive the post-COVID-19 pandemic by applying the triple bottom line (TBL) approach in formulating strategies and increasing investments to develop sustainable innovations.

The article explores B Corps, which has received minimal attention in the literature, to propose a deeper understanding of the topic.

In 2014, the Colombian Government commissioned a unique national survey on illegal liquor. Interviewers purchased bottles of liquor from interviewees and tested them for authenticity in a laboratory. Two factors predict whether liquor is contraband (smuggled): (1) the absence of a receipt and (2) the presence of a discount offered by the seller. Neither factor predicts whether a bottle is adulterated. The results back a story in which sellers are complicit with a contraband economy, but whether buyers are complicit remains unclear. However, buyers are more likely to receive adulterated liquor when specifically asking for a discount.

This chapter critically discusses the many positive aspects that are ascribed to gazelle firms by exploring the external effects and dark sides of high firm growth. On the background of the more general debate on purpose versus profit as a firm’s mission, the chapter theoretically elaborates on the dichotomy between quantitative and qualitative growth of gazelles. This is followed by a case-based illustration and exploration as to how quantitative and qualitative growth interrelates in gazelles and what are impediments for high growth that is purpose driven. The chapter closes with a discussion of the Janus-faced nature of gazelles and how their corporate citizenship can be enhanced.

The purpose of this paper is to examine the influences of employee perception of corporate social responsibility (CSR) in the Readymade Garment Industry (RMG). The RMG industry in Bangladesh has faced constant criticism of their working practices, and following some fatal incidents, the industry was faced with external pressures of implementing CSR practices and policies. Manufacturers invested and initiated CSR in their business and marketing strategy to survive in the global competition. Employees are internal stakeholders that help to implement and disseminate strategies successfully; however, there is not enough knowledge in the area of employee perception of CSR.

The paper is an exploratory study using the quantitative data collection method. In total, 128 responses have been collected from participants who are employees of garment factories in Bangladesh to understand their perception of CSR. Regression analysis has been conducted to ascertain the relationships between the factors that influence employee perception. Theories of stakeholder management, organizational citizenship behaviour, social exchange theory and employee engagement have been used to analyse the factors that influence employee perception.

The findings show that the factors that influence perception of CSR are not confined to the stakeholder’s initiatives but are significantly dependent on the employees’ direct involvement, engagement and personal values as a beneficiary and an executioner. In addition to the stakeholder’s initiatives that are a key deliverable to the marketing strategy, the employees are influenced by their personal beliefs and practices that can be associated with influences of religion, culture and the wider social landscape.

The data is limited to a small number of factories located near the capital, Dhaka, this is a small sample compared to the 4,000 factories in Bangladesh. Further research can be conducted based on a larger data set, which could represent a wider range of employee perspectives from different factories relating to size, product category and geographical location. The study does not expand on the factors that influence employee perception specifically.

The findings of the study can help the employers understand that the organization’s priority and participation are not the only factors that influence the employee’s perceptions. The employees’ assessment of the stakeholder’s intentions of CSR, which are reflected in the organization’s priority, shapes employee perceptions that are influenced by their personal values and beliefs. The awareness of the factors that influence the employees will enable organizations to motivate them and deliver on expectations of the business partners.

It is the practices aimed at the employees that enhance their engagement in CSR that enable them to reciprocate and influence their perception of the organization’s fair and genuine motives. The effectiveness of this aids the macro-marketing aspects of managing social concerns and the impact of businesses.

The data collected is primary data from employees of garment manufacturers. The hypothesized framework is developed by the authors, and the outcomes of the factors that influence the employee perception of CSR are escalated from the analysis conducted by the authors.

Many of the human communities that comprise the South have cosmologies that place human and nonhuman animals on a continuum. Culturism, with its foreign logic and dynamics, has broken this continuum, thereby fuelling speciesist practices. In this chapter, I portray the deep relation that some rural Southern communities have with nonhuman animals, and analyse some of the imposed logics that lead the South to abuse nonhuman animals while denying that what they are doing is mistreatment.
