The North American Journal of Economics and Finance, volume 53. Abstract: This study examines the effect of the transparency of central banks communication on credit market. In particular, this study investigates how central banks’ effort to provide more detailed information about their objectives regarding the price stability (monetary policy transparency) and financial stability (financial stability transparency) policies are able to mitigate information asymmetry on credit market, through the net interest margin charged by the banks to engage in financial intermediation (credit spread). The findings denote central bank transparency is able to reduce the credit spread. Additionally, the evidence suggests the effect of central bank transparency on the credit spread is greater in emerging markets, where there is less information available on credit market. In brief, transparency in central banks communication is an important tool to mitigate the information asymmetry in the credit market.

Revista de Administração Contemporânea, volume 24, issue 5, pp. 474-486. Abstract: This is a case for teaching focused on the internationalization process of Brazilian Secrets Hair (BSH), a company that has considered the world as its target market since its start, and is part of an ever-growing segment: the cosmetics industry. Upon understanding the company’s international expansion, the internationalization theories within the behavioral approach, such as the Uppsala theory, the network theory, the entrepreneurship perspective, and the effectuation logic, can be explored, answering questions related to market selection processes, entry mode choices, and global expansion strategy decisions. This case was based on primary and secondary data from a real company and was originally designed for international business classes of graduate courses.

The North American Journal of Economics and Finance, volume 52. Abstract: Although performance analysis has become a vital part of the banking industry, research on the efficiency of Portuguese banking remains scarce and focused on discussing rankings to the detriment of unveiling its productive structure relative to its competition. This issue is of utmost importance considering the relevant transformations in the Portuguese economy over the last ten years. In this study, we developed a network productive structure comprising two paradigms (the production and intermediation approaches, respectively) to assess how market competition and other macro-economic variables impact bank efficiency and their feedback effects in Portugal. Unlike previous research, an integrated multi-layer perceptron (MLP)/hidden Markov model (HMM) was used for the first time to unveil endogeneity among banking competition, macro-economic variables, and the efficiency levels of the production and intermediation approaches in banking. The findings illustrate the pattern of interaction among these variables and verify that the production efficiency is the cornerstone of endogeneity in Portuguese banks. Policy makers will find the results helpful.

Research in Economics, volume 74, issue 1, pp. 87-93. Abstract: This literature review maps recent studies addressing supply chain management (SCM) in the healthcare sector through a systematic approach that synthesises 74 empirical studies (2006–2016). Our approach adopts a network lens to map the literature and offers key contributions to the field. First, we show that there is a lack of network level studies. Second, there is an imbalance of research attention regarding the various types of supply, namely health services, medicines, medical supplies and blood supply. Third, we underline the advantages of the network lens, indicating network actors and flows between those actors that need further research. Fourth, we show an alarming lack of theoretical lens in healthcare SCM studies and draw attention to the fact that even when explicitly adopting a theory, some studies show inconsistencies between theoretical lens and level of analysis. Ultimately, we offer a map of future research for healthcare SCM through a network lens in order to improve the understanding the complexities of the healthcare sector.

Research in Economics, volume 74, issue 1, pp. 87-93. Abstract: Using a sample of 12,982 Brazilian professional accountants collected in 2012, we show that reflective accountants receive higher job compensation (wages) compared to their impulsive peers. Results are robust to matching on gender, age, education, number of children, place of residence, and job-related covariates. Results were also replicated in a sample of 1,932 professional accountants collected in 2017 with a different cognitive reflection scale, showing the persistence and robustness of the effect either to an alternative proxy for cognitive reflection and a different timeframe.

Energies, volume 13, issue 9. Abstract: This paper analyzes the efficiency of thermal power plants in Angola by means of a two-stage Data Envelopment Analysis (DEA) approach. In the first stage, a novel super-efficiency DEA model for undesirable outputs (CO2 emission levels and discharge of polluted water) is initially used to measure their efficiency levels. Then, in the second stage, relevant cost structure variables frequently used to describe a productive technology are employed as analytical thresholds for assessing energy production performance either in terms of capital or labor-intensity levels. Precisely, bootstrapped regression trees are used to discriminate super-efficiency scores yielding an energy production performance predictive model based on the technology type as proxied by its cost structure and their respective thresholds, since Angolan thermal plants are heterogeneous. Findings suggest that Angolan power plants are old and labor intensive, as some of them date back to the colonial era, and that lack of capital investment should be revised in favor of installing carbon capture devices. The approach developed here consists of a valuable approach for identifying priorities when technologically updating a heterogeneous thermal industry to face pollutant concerns.

Corporate Ownership & Control, volume 17, issue 3, 134-145. Abstract: This article investigates the association between RPTs, disclosure, ownership structure, and performance in Brazil and uses a hand-collected sample of 3,790 Brazilian RPT contracts obtained from corporate filings of a representative and randomly drawn sample of public companies from 2010 through 2012. Firms with greater conflicts of interest potential may employ less RPTs to signal that there will be no abuse. There is a negative and significant relationship between RPT values and accounting performance, but the same is not true for market value. The evidence in this article contrasts with that presented in national surveys by Matos and Galdi (2014) and Silveira, Prado, and Sasso (2009a), which may reflect different methodological choices. Companies and market participants may realize that some types of RPTs are beneficial and others harmful to minority shareholders and their short and long term impacts on performance are not the same. The evidence suggests that both the hypothesis of efficient economic transactions and of the conflict of interest may have merit depending on the type of RPT and the performance metrics.

Benchmarking: An International Journal, volume 27, issue 3, pp. 1188-1209. Abstract Purpose: The aim of this paper is to provide an approach to analyze the performance of TV programs and to identify what can be done to improve them. Design/methodology/approach: The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), the Ng-model, Grey relational analysis (GRA), and principal component analysis (PCA) were applied to evaluate the programs, using audience, share, and duration as the performance criteria. Findings: By comparing TOPSIS to the Ng-model, PCA, and GRA, we verified that SVD and bootstrap SVD TOPSIS provide a good balance between equal-weights TOPSIS and the other models. This is because SVD and bootstrap SVD TOPSIS break down the data to a higher degree, but are less impacted by outliers compared to the long tail models. Practical implications: To determine which TV programs should be replaced or modified is a complex decision that has not been addressed in the literature. The advantage of using a multi-criteria decision-making (MCDM) approach is that analysts can choose as many criteria as they want to rank TV programs, rather than relying on a single criterion (e.g., audience, share, target rating point). Originality/value: This work represents the first time that robust MCDM methodology is applied to an audience data set to analyze the performance of TV programs and to identify what can be done to improve them. This study shows the application of a detailed methodology that is useful for the improvement of TV programs and other entertainment industry content.

Sustainability, volume 12, issue 2, pp. 1-47. Abstract: This paper presents the main messages of a South American expert roundtable (ERT) on the unintended side effects (unseens) of digital transformation. The input of the ERT comprised 39 propositions from 20 experts representing 11 different perspectives. The two-day ERT discussed the main drivers and challenges as well as vulnerabilities or unseens and provided suggestions for: (i) the mechanisms underlying major unseens; (ii) understanding possible ways in which rebound effects of digital transformation may become the subject of overarching research in three main categories of impact: development factors, society, and individuals; and (iii) a set of potential action domains for transdisciplinary follow-up processes, including a case study in Brazil. A content analysis of the propositions and related mechanisms provided insights in the genesis of unseens by identifying 15 interrelated causal mechanisms related to critical issues/concerns. Additionally, a cluster analysis (CLA) was applied to structure the challenges and critical developments in South America. The discussion elaborated the genesis, dynamics, and impacts of (groups of) unseens such as the digital divide (that affects most countries that are not included in the development of digital business, management, production, etc. tools) or the challenge of restructuring small- and medium-sized enterprises (whose service is digitally substituted by digital devices). We identify specific issues and effects (for most South American countries) such as lack of governmental structure, challenging geographical structures (e.g., inclusion in high-performance transmission power), or the digital readiness of (wide parts) of society. One scientific contribution of the paper is related to the presented methodology that provides insights into the phenomena, the causal chains underlying “wanted/positive” and “unwanted/negative” effects, and the processes and mechanisms of societal changes caused by digitalization.
