We study here the effects of FTA on demand, consumer surplus, dealer profit, and tariff revenue depending on the degree of substitution between two goods and import competition structure in a two country’s static model. We consider monopolist dealer, and perfect competition in imports market. The base model is with a positive tariff and we compare the equilibrium with a zero tariff under FTA. The rankings in the consumer utility are such that it is i) the highest under perfect competition with FTA or without FTA, ii) second highest under monopoly with FTA, and iii) the lowest under monopoly without FTA.

The purpose of this paper is to investigate social capital's effect on family business development in selected family media firms.

The statistical population includes 100 individuals who run a family business in this industry. Eighty individuals are selected as the research sample through the stratified random sampling method. The data are collected using a questionnaire. The authors used structural equation modelling method for data analysis.

The results indicate that social capital affects the development of family businesses in media firms. According to the results obtained from the structural equation test, the effect of the relational dimension of social capital on trust and the effect of the cognitive and structural dimensions of social capital on trust are supported, while the effect of the relational dimension of social capital on commitment as well as the effect of the cognitive dimension of social capital on trust are not supported.

This research could help family firms in media industries improve trust and commitment by paying attention to different aspects of social capital. Besides, it shows that even the impact of relational and cognitive social capital, respectively, on commitment and trust, are not supported; these two could affect trust and commitment, respectively.

The paper is among the first studies that investigate family firms in media industries. Besides, the relationships between relational, cognitive and structural aspects of social capital and trust and commitment are rarely studied in the literature as two determinants of family business development.

This study aims to analyse whether investment in green and sustainable stocks provide some cushion during current precarious time. To compare the impact of COVID-19 on the volatility of sustainable and market-capitalisation-based stocks, daily returns from Greenex, Carbonex, Large-Cap, Mid-Cap and Small-Cap index have been analysed over a period of six years from 2015 to 2021.

At the outset, logarithmic return of all selected indices has been tested for possible unit root and heteroscedastic. On confirmation of stationarity and heteroscedasticity of data, auto-regressive conditional heteroscedastic models have been applied. Thereafter, volatility is modelled through best suitable model as suggested by Akaike and Schwarz information criterions.

The findings indicate the positive impact of COVID-19 on the volatility of the indices. Asymmetric power ARCH model indicates highest significant impact of COVID-19 over the volatility of Large-Cap index, whereas exponential GARCH model detected highest significant impact of COVID-19 over the volatility of Mid-Cap Index.

To the best of the authors’ knowledge, the present study is original in the sense that it aimed at comparing the possible impact of COVID-19 over sustainable and market-capitalisation-based indices.

The Group of 20 (G20) is tasked with responding to economic shocks in the global financial system, with COVID-19 having proved to be the most significant shock since the G20's inception. COVID-19 also represents the first economic crisis accompanied by a concerted attempt to “build back better”, principally through a climate-compatible recovery. In 2021, there is little clarity as to the G20's response to this challenge, primarily due to considerable divergence in the green stimulus practices of its member states. The paper aims to investigate whether the G20, climate change and COVID-19 are critical juncture or critical wound.

Historical institutionalism (HI) suggests that one can explain an institution's future response by reference to its developmental pathway to date. This contribution adopts its concept of “critical junctures” to shed light on the G20's possible institutional response to COVID-19. The contribution undertakes a comparative analysis of the global financial crisis (GFC) and COVID-19 as possible critical junctures for the G20.

In doing so, the work demonstrates that the G20 “building back better” from COVID-19 requires a shift away from its institutional orthodoxy to a much larger degree than its response to the GFC. Accordingly, whilst both the GFC and COVID-19 may be considered critical junctures for the G20, only COVID-19 has the potential to be a “critical wound” that leads to institutional redundancy.

Through interrogating this further, this exposition prospectively outlines two possible futures the G20 faces as a consequence of COVID-19: reform or redundancy. In this way, it offers an ex ante perspective on policy-reform options for the G20's ongoing response to COVID-19.

Whichever choice the G20 makes in its response to COVID-19 has profound consequences for global governance in an increasingly unpredictable world.

Herein lies the importance of an exploratory assessment of COVID-19 as a critical juncture or a critical wound for the G20.

This study aims to identify different consumer segments to address the strategies that can be adopted by companies and policymakers to increase the consumption of safer foods and reduce the negative externalities caused by pesticides. More than 3,000 consumers were involved in the survey, of which more than 1,000 completed in all parts.

The complexity of the topic required a multidimensional approach. Therefore, the authors modelled the decision support system by proposing a decision rule-based approach to analyse consumers' food purchasing choices. More precisely, the authors referred to the dominance-based rough set approach (DRSA).

Based on the DRSA results, three consumer segments were identified: green consumers, integrated pest management (IPM)-informed and active consumers, and potential low-pesticide consumers for which different policy implications have been highlighted.

Despite the high number of survey respondents, further research should seek to obtain data from a more balanced sample. Furthermore, different methods of analysis could be applied and the results compared.

Identification and promotion of managerial and public policies to increase the consumption of low pesticide food.

The main social implications can be summarised in the greater knowledge and awareness of the environmental aspects related to food, recognition of the intrinsic quality and/or functionality of food.

The authors contribute to the literature in two ways. First, the authors refer to the DRSA, an innovative approach in the context of consumer analysis. Second, based on the decision rules, the authors identify three consumer segments to which specific tools can be addressed.

Workplace silence impedes productivity, job satisfaction and retention, key issues for the hospital workforce worldwide. It can have a negative effect on patient outcomes and safety and human resources in healthcare organisations. This study aims to examine factors that influence workplace silence among hospital doctors in Ireland.

A national, cross-sectional, online survey of hospital doctors in Ireland was conducted in October–November 2019; 1,070 hospital doctors responded. This paper focuses on responses to the question “If you had concerns about your working conditions, would you raise them?”. In total, 227 hospital doctor respondents (25%) stated that they would not raise concerns about their working conditions. Qualitative thematic analysis was carried out on free-text responses to explore why these doctors choose to opt for silence regarding their working conditions.

Reputational risk, lack of energy and time, a perceived inability to effect change and cultural norms all discourage doctors from raising concerns about working conditions. Apathy arose as change to working conditions was perceived as highly unlikely. In turn, this had scope to lead to neglect and exit. Voice was seen as risky for some respondents, who feared that complaining could damage their career prospects and workplace relationships.

This study highlights the systemic, cultural and practical issues that pressure hospital doctors in Ireland to opt for silence around working conditions. It adds to the literature on workplace silence and voice within the medical profession and provides a framework for comparative analysis of doctors' silence and voice in other settings.

Previous literature provides mixed evidence about the effectiveness of a code of ethics in limiting managerial opportunism. While some studies find that code of ethics is merely window-dressing, others find that they do influence managers' behavior. The present study investigates whether the quality of a code of ethics decreases the cost of equity by limiting managerial opportunism.

In order to test the hypothesis, the authors perform an empirical analysis on a sample of US companies in the 2004–2012 period. The results are robust to a battery of robustness analyses that the authors performed in order to take care of endogeneity.

Empirical results indicate that a higher quality code of ethics is associated with a lower cost of equity. In other words, firms with a more comprehensive code of ethics and better-designed implementation procedures limit managerial opportunism and pay a lower cost of equity because they are perceived by investors to be less risky.

The authors contribute to the literature in two ways. First, by looking at the market reaction to the code of ethics, thus capturing all its indirect possible benefits and second, by measuring not only the existence but also the quality of a code of ethics. Based on the results, policymakers may choose to further promote codes of ethics as an effective corporate governance mechanism.
