Abstract

Purpose

The purpose of this study is to investigate the influence of firm-specific investor sentiment on Brazilian companies’ accrual-based earnings management between 2010 and 2018. The paper aims to bring deeper insight into the relationship between the investor expectations and managers’ decision-making in an emerging market.

Design/methodology/approach

The authors use the quantitative approach and apply a multiple linear regression model to test the relationship among the abnormal accruals, the firm-specific investor sentiment index and the control variables. The final sample includes data from 175 companies, between 2010 and 2018.

Findings

These results reveal a negative association between firm-specific investor sentiment and accrual-based earnings management, which could mean that the risk propensity of managers to manipulate earnings increases when they face known losses in the capital market.

Research limitations/implications

The research findings provide a valuable understanding of how emerging capital market expectations can influence managerial decisions, such as accrual-based earnings management. The geographical area of study was limited to only Brazil.

Originality/value

Previous studies on developed markets show that market-wide investor sentiment positively influences accrual-based earnings management. However, the present study shows that the firm-specific investor sentiment index has a significant and negative relationship with Brazilian companies’ earnings manipulation, whereas market sentiment indicates contradictory relationship in previous studies in the country.

Propósito

El propósito de este estudio es investigar la influencia del sentimiento de los inversionistas a nivel de empresa en la manipulación contable de las empresas brasileñas entre 2010 y 2018. El documento pretende aportar una visión más profunda sobre la relación entre las expectativas de los inversores y la toma de decisiones de los gestores en un mercado emergente.

Diseño/metodologia/enfoque

usamos el enfoque cuantitativo y aplicamos un modelo de regresión lineal múltiple para probar la relación entre las acumulaciones anormales, el índice de sentimiento de los inversores a nivel de empresa y las variables de control. La muestra final incluye datos de 175 empresas, entre 2010 y 2018.

Hallazgos

Los resultados revelan una asociación negativa entre el sentimiento de los inversores a nivel de empresa y la manipulación contable basada em acumulaciones, lo que podría significar que la propensión al riesgo de los administradores a manipular las ganancias aumenta cuando enfrentan pérdidas conocidas en el mercado de capitales.

Limitaciones/implicaciones de la investigación

los resultados de la investigación proporcionan una valiosa comprensión de cómo las expectativas de los mercados de capitales emergentes pueden influir en las decisiones de gestión, como la manipulación contable basada en acumulaciones. El área geográfica de estudio se limitó únicamente a Brasil y, en consecuencia, los hallazgos y conclusiones del estudio tuvieron sus límites.

Originalidad/valor

estudios anteriores sobre mercados desarrollados muestran que el sentimiento de los inversores a nivel de mercado influye positivamente en la manipulación contable. Sin embargo, el presente estudio muestra que el índice de sentimiento de los inversores a nivel de empresa tiene una relación significativa y negativa con la manipulación de las ganancias de las empresas brasileñas, mientras que el sentimiento del mercado indica una relación contradictoria en estudios anteriores en el país.

Abstract

Purpose

The purpose of this study was to uncover representative emergent areas and to examine the research area of marketing, tourism and big data (BD) to assess how these thematic areas have developed over a 27-year time period from 1996 to 2022. This study analyzed 1,152 studies to identify the principal thematic areas and emergent topics, principal theories used, predominant forms of analysis and the most productive authors in terms of research.

Design/methodology/approach

The articles for this research were all selected from the Web of Science database. A systematic and quantitative literature review was performed. This study used SciMAT software to extract indicators. Specifically, this study analyzed productivity and produced a science map.

Findings

The findings suggest that interest in this area has increased gradually. The outputs also reveal the innovative effort of industry in new technologies for developing models for tourism marketing. Ten research areas were identified: “destination marketing,” “mobility patterns,” “co-creation,” “gastronomy,” “sustainability,” “tourist behavior,” “market segmentation,” “artificial neural networks,” “pricing” and “tourist satisfaction.”

Originality/value

This work is unique in proposing an agenda for future research into tourism marketing research with new technologies such as BD and artificial intelligence techniques. In addition, the results presented here fill the current gap in the research since while there have been literature reviews covering tourism with BD or marketing, these areas have not been studied as a whole.

Propósito

Analizamos 1.152 investigaciones para identificar las principales áreas temáticas y temas emergentes, las principales teorías utilizadas, las formas de análisis predominantes y los autores más productivos en términos de investigación.

Metodología

Todos los artículos para esta investigación fueron seleccionados de la base de datos Web of Science. Realizamos una revisión sistemática y cuantitativa de la literatura. Utilizamos el software SciMAT para extraer indicadores. Específicamente, analizamos la productividad y elaboramos un mapeo científico.

Hallazgos

Los hallazgos sugieren que el interés en esta área ha aumentado gradualmente. Los resultados también revelan el esfuerzo innovador de la industria en nuevas tecnologías para desarrollar modelos de marketing turístico. Se identificaron diez áreas de investigación (“marketing de destinos”, “patrones de movilidad”, “co-creación”, “gastronomía”, “sostenibilidad”, “comportamiento turístico”, “segmentación de mercado”, “redes neuronales artificiales”, “precios”, y “satisfacción del turista”).

Valor

Este trabajo es único al proponer una agenda para futuras investigaciones en investigación de Marketing Turístico con nuevas tecnologías como Big Data y técnicas de Inteligencia Artificial. Además, los resultados presentados aquí llenan el vacío actual en la investigación ya que si bien se han realizado revisiones de literatura que cubren Turismo con Big Data o Marketing, estas áreas no se han estudiado como un conjunto.

Abstract

Propósito

Identificar los aspectos que los Actores Sociales consideran en la construcción de futuros compartidos en las comunidades. En su aplicación en los países emergentes, especialmente en el Sur Global, a menudo se pasan por alto las particularidades socioculturales de las comunidades y los actores, generando fricciones o conflictos sociales. Este artículo presenta dos elementos críticos que contribuyen al debate: a) la importancia de entender a los Actores Sociales dentro de un modelo de generación de futuros comunitarios en los países emergentes; b) los factores relevantes que influyen en los actores en un ejercicio de construcción de futuros en las comunidades.

Diseño/metodología/enfoque

A partir de la investigación cualitativa, se utilizó un estudio de caso de prospectiva comunitaria del futuro: El futuro de Puerto Gaitán 2037 (Meta, Colombia). Se aplicó un método de recolección de información a partir de la observación de los participantes y el análisis de la documentación. El método de análisis fue el DQA (Análisis Cualitativo Deductivo).

Hallazgos

La participación de Los Actores Sociales presenta un modelo de cinco elementos relevantes que influyen en los actores para la construcción exitosa de futuros en las comunidades. Los primeros cuatro factores, revelados por la teoría, existen en la realidad. Asimismo, se demuestra un quinto factor: el Pensamiento a Largo Plazo, que se evidencia en un Modelo de aplicación de Estudios de Futuros para el contexto específico, aplicable al caso de comunidades en países del Sur Global.

Originalidad/valor

Si bien existen ejemplos aislados de recomendaciones respecto a estudios para generar el futuro de las comunidades, este es el primer estudio que presenta factores concretos que contribuyen a orientar la construcción de futuros comunitarios desde Actores Sociales, especialmente en países del Sur Global como Colombia. También es uno de los primeros estudios en utilizar el DQA como método de análisis en un tema de Estudios de Futuros.

Abstract

Purpose

The current research inspects the moderation role of ownership concentration on chief executive officer (CEO) characteristics and real earnings management (REM) relationship in Jordan.

Design/methodology/approach

Driscoll–Kraay regressions were run using data from 348 firm-year observations for companies listed on the Amman Stock Exchange between 2013 and 2018.

Findings

Driscoll–Kraay regressions demonstrate that CEO experience, tenure and political connections improve REM practices. Ownership concentration diminishes and limits REM practices when combined with CEO experience, tenure and political connections, since all three have a negative and significant link with REM.

Research limitations/implications

Initial constraints include the study’s lack of generalisability due to a small number of CEO-related parameters. Second, critics of the ideal model for judging EM have a foreseeable flaw. No generally accepted model is perfect.

Practical implications

This study’s conclusions are crucial for industry participants, including companies, policymakers, investors and the general public. These findings will help investors, practitioners and regulators understand that businesses with significant ownership concentrations and experienced CEOs have superior earnings and low REM practises.

Social implications

The findings of this study have an optimistic impact on the existing body of knowledge. The current literature has yet to properly inspect the moderation role that ownership concentration has on the connotation between CEO characteristics and EM.

Originality/value

Despite several research studies in both developed and developing nations, ownership concentration has been almost virtually neglected. The current study could fill a hole in earlier research, rendering it a novel study.

Abstract

Purpose

The aim of the study was to analyze the performance of Black-Litterman (BL) portfolios using a views estimation procedure that simulates investor forecasts based on technical analysis.

Design/methodology/approach

Ibovespa, S&P500, Bitcoin and interbank deposit rate (IDR) indexes were respectively considered proxies for the national, international, cryptocurrency and fixed income stock markets. Forecasts were made out of the sample aiming at incorporating them in the BL model, using several portfolio weighting methods from June 13, 2013 to August 30, 2022.

Findings

The Sharpe, Treynor and Omega ratios point out that the proposed model, considering only variable return assets, generates portfolios with performances superior to their traditionally calculated counterparts, with emphasis on the risk parity portfolio. Nonetheless, the inclusion of the IDR leads to performance losses, especially in scenarios with lower risk tolerance. And finally, given the impact of turnover, the naive portfolio was also detected as a viable alternative.

Practical implications

The results obtained can contribute to improve investors practices, specifically by validating both the performance improvement – when including foreign assets and cryptocurrencies –, and the application of the BL model for asset pricing.

Originality/value

The main contributions of the study are: performance analysis incorporating cryptocurrencies and international assets in an uncertain recent period; the use of a methodology to compute the views simulating the behavior of managers using technical analysis; and comparing the performance of portfolio management strategies based on the BL model, taking into account different levels of risk and uncertainty.

Abstract

Purpose

An interaction between emerging technologies (ETs) for facility management (FM) activities and stakeholder skills is necessary to promote the optimization of FM performance. Previous studies do not show strategies for the selection of ETs in FM considering the technological competencies of stakeholders. Thus, this study analyzes the interactions between ETs and FM from the perceptions of Brazilian professionals, identifying the most appropriate and effective technological solutions, based on a broad literature review.

Design/methodology/approach

The steps of the methodology are as follows: systematic literature review (SLR); detailing the ETs for FM; online questionnaire based on SLR findings; sample of Brazilian FM professionals; statistical treatment; and discussion.

Findings

Results indicate wireless sensor network, Internet of Thing, building information modeling and Big Data as ETs in FM with greater potential for optimization in the performance of FM activities, from survey respondents.

Research limitations/implications

The scope of possible findings may have been biased, considering the small number of research participants and current transformations resulting from the COVID-19 pandemic (e.g. changes to standard operating procedures).

Practical implications

The results ensure greater security to facility managers in the effective implementation of ETs in FM activities.

Originality/value

The research explores the published studies and the consultation with Brazilian FM professionals in the selection of ETs.
