Tourism may have important positive and negative economic, socio-cultural and environmental impacts. However, cultural and natural resources are also the base to the development of competitive destinations and changes in these resources can have an important impact on tourism development. Despite the considerable literature regarding the impacts of tourism, a limited number of studies examine the impact of the environment on tourism, specifically the impact of air quality (AQ). Therefore, this paper aims to review what is known about the impact of AQ on tourism demand, analysing the different methods and approaches used, as well as the results obtained.

A systematic literature review method was used to examine the state of the art in this topic and identify research gaps and new research directions. Only 26 papers were identified that examine the impact of AQ on tourism demand.

The majority of the studies were carried out in China and investigate the impact of AQ on tourism from the perspective of tourism demand. Both global (tourism demand) and individual (tourist perceptions) approaches have been used to investigate the impact of AQ on tourism.

This is the first systematic literature review on the impact of outdoor AQ on tourism demand. Moreover, this paper analyses the methods and approaches that have been used in the literature to examine the impact of outdoor AQ on tourism demand. The paper ends with a discussion on the identified research gaps concerning the influence of AQ on tourism development.

The investigation of the relationship between gender diversity and corporate risk-taking is a recent stream of research. In this study, the authors propose an answer to the following main question: What do the authors know about gender effects in corporate risk-taking and how should we proceed?

In order to ensure the quality and the objectiveness of the literature review, the authors selected articles published in journals that are simultaneously ranked by the Chartered Association of Business Schools (ABS, 2018) and by the Journal Citation Reports (JCR, 2018), focused on the Board of Directors (BoD) and Top Management Teams (TMT).

The literature review reveals that women's presence on the BoD and TMT impacts corporate risk-taking in different ways. Based on the analysis, it is possible to organize the extant findings in two major categories, according to gender measures, firm type and country of origin: (1) universal effects – women decrease firms' litigation risk, failure risk and operational risk while they have no significant effect on insolvency risk and; (2) contingent effects – women have contingent effects on financial risk, manipulation risk, total risk, idiosyncratic risk and systematic risk.

Covering several different research fields, this study provides a comprehensive review concerning what the authors know regarding the effects of the BoD and TMT gender diversity in corporate risk-taking. The authors present a model summarizing empirical findings and propose a number of avenues for future research.

This study aims to examine the role of financial inclusion and institutional factors such as corruption and the rule of law (RL) on the credit risk and stability of banks.

The study considers a sample of 61 developing countries and uses very robust estimation techniques that allow controlling for endogeneity, heteroskedasticity and serial correlation, such as instrumental variables method in two-stage least squares (IV-2SLS), instrumental variables generalized method of moments (IV-GMM), as well as system of generalized methods of moments in two stages (Sys-2GMM).

The results confirm that financial inclusion and strengthening the RL can significantly contribute to reducing credit risk and improving the financial stability of banks; in contrast, the authors find that weak control of corruption aggravates credit risk. In addition, they found that greater competitiveness in the banking sector increases credit risk.

This study supports the need to promote financial inclusion and strengthen institutional factors to improve the stability of the banking sector, as well as promote general well-being in the economy.

This study contributes to the scarce literature by simultaneously using institutional factors such as corruption and the RL and macroeconomic variables such as economic growth and inflation in the relationship between financial inclusion and the banking sector, as well as considering competitiveness as an explanatory factor for banks’ credit risk and stability.

This study aims to examine the impact of financial inclusion and financial innovation on corruption, considering the moderating role of education, as well as identify the specific modality of digital inclusion and payments that contribute to corruption reduction.

The study uses a representative sample consisting of 46 African countries in three different years 2011, 2014 and 2017. On the data, feasible generalized least squares (FGLS), instrumental variables – two stages least squares (IV-2SLS) and two-stage generalized method of moments (IV-2GMM) model estimation methods were employed.

The results suggest that financial inclusion and education significantly reduce corruption. As well, the interaction between financial inclusion and education reduces corruption. Additionally, the authors find that the expansion of bank credit and the use of credit and debit cards are the specific modes of financial inclusion and digital payments that can contribute to corruption reduction.

This study awakens policymakers in African countries about the need to consider education as an alternative measure to support financial inclusion and reduce the use of physical cash in transactions for an effective fight against corruption.

Regarding practical implications, the study shows that financial inclusion besides reducing poverty for households can contribute to macroeconomic stability in Africa.

The study uses a representative sample composed of 46 African countries and considers the role of education in moderating the relationship between financial inclusion and financial innovation on corruption. Furthermore, the study identifies the specific modality of financial inclusion and digital payments that contribute to corruption reduction.

This article aims to verify if there are detectable barriers in price levels that are understood to be psychologically important (psychological barriers) in a set of hourly electricity prices. These barriers manifest themselves when the market struggles with a difficulty in crossing the barrier to a different level. Psychological barriers focus on directional price movements around regions of the barrier, thus the importance of understanding investor behavior. The authors intend to contribute empirically to the scarce literature on psychological influences in individuals trading in the energy market, hereby enhancing the knowledge concerning the behavior of investors in this market.

The present work aims to test psychological barriers in the Nord Pool electricity market. Through a sample of hourly data on the Elspot day-ahead market, from 2013 to 2017, three groups of tests were made, following the M-values methodology: (1) uniformity tests, which clearly rejected the uniformity in hourly prices; (2) barrier tests, which included the barrier proximity and barrier hump tests, evidencing psychological barriers and (3) conditional effects tests, which allowed us to conclude in favor of effects of positive returns after approaching a barrier on an upward movement, i.e. the barrier breaches due to the fact that increasing prices tend to lead to further price increases, on average.

Uniformity tests, rejected the uniformity in hourly prices; barrier tests, included the barrier proximity and barrier hump tests, evidencing psychological barriers and conditional effects tests, allowed us to conclude in favor of effects of positive returns after approaching a barrier on an upward movement, i.e. the barrier breaches due to the fact that increasing prices tend to lead to further price increases, on average. Another relevant conclusion is that the period from midnight to 9 a.m. is very sensitive, since there is evidence of return and variance effects simultaneously. The implications of these results are potentially relevant, since changes on the variance are usually perceived as a proxy for risk, with changes on the return. It was also concluded that with the increase of the time span from 5 to 10 days on the conditional effects difference tests, there were significant changes on the results, the variance effect is stronger, while the return effect weakens.

However, this research presents some limitations that result in representing opportunities for future research. The fact that there are reduced data available for other markets end up limiting the study of the global electricity market. Although Nord Pool is Europe's leading energy market and is seen as one of the most successful energy markets in the world, it would be interesting to do a study with more than one electricity market to make comparative considerations. Although the spot market is the main arena for energy trade, while the intraday market works as a compliment, it would be equally interesting to do a similar study for the intraday market and then compare conclusions. Moreover, in the present study, it was used standard methods in the literature on psychological barriers, but other methods could have been used–for example, those that assume that prices follow the Benford's distribution (Lu and Giles, 2010), which also present a path for future research and opportunity for confirming the robustness of the present results.

When the presence of psychological barriers is detected it means that the risk-return relationship becomes weaker around the psychological barrier (round numbers, meaning that electricity traders anchor). Identification of psychological barriers supports the claim that technical analysis strategies based on price support and resistance can be profitable. Therefore, more profitable strategies can be built by traders, but no reconciliation with the efficient market hypothesis (EMH) (provided that in inefficient markets prices should not exhibit any particular pattern). The finding of significant psychological barriers in specific hourly time intervals implies the need to address its practical implications in electricity markets, being so specific, namely, the possibility to earn extraordinarily profits exploiting this anomaly and who wins.

The electricity sector is a determinant sector in economic growth and a factor of development. Herein lies the importance of studying this market, which until now has not occurred in this subject, as far as it was possible to gauge. Are there barriers in the electricity market and should such a presence be taken into account? Investigating the existence of psychological barriers in the electric market becomes relevant, because knowing that investors are psychologically affected by a psychological barrier, can become a useful tool in negotiation, as it can function as another variable in the “equation” which is to trade in a complex market like this. Proving the potential presence of a psychological barrier may lead investors to believe in the idea of levels of resistance or levels of support, affecting their decision-making and price dynamics.

This paper seeks to analyze stylized statistical properties of the recent traded asset CO₂ emission allowances, for spot and futures returns, examining also the relation linking convenience yield and risk premium, for the German European Energy Exchange (EEX) between October 2005 and October 2009.

The study was conducted through empirical estimations of CO₂ allowances risk premium, convenience yield, and their relationships.

Future prices from an ex-post perspective are examined to show evidence for significant negative risk premium, or a positive forward premium. A positive relationship between risk premium and time-to-maturity is found. Both financial concepts are found to be negatively affected by spot price volatility. Convenience yield is positively influenced by CO₂ price, while influencing the risk premium positively.

From a financial perspective, allowances seem to be producing the desired effects in terms of environmental policies, although a lot more remains to be done. The presence of risk premium and convenience yield makes it clear that agents act in this commodity market according to risk consideration. Results change depending on phase and futures contracts used for the determination of both financial terms, indicating that uncertainties over the future of EU-ETS seem to be decreasing.

Previous research has mainly focused on the first phase of the EU-ETS (2005-2007), whereas this paper extends the analysis period here. The paper finds some opposite results compared with previous commodities theories and designs some policy implications, given the results attained.

The study aims to build upon the Resource-based view of the firm (RBV) and Dynamic Capability Theory (DCT) to perform a meta-analysis on the eco-innovation/SMEs’ sustainable performance relationship.

Employing a psychometric meta-analytic approach with a random-effects model, the study examines a sample of 134,841 SMEs covering 99 studies and 233 study effects. Subgroup and meta-regression analysis were used to test the study`s hypotheses in Comprehensive Meta-Analysis (CMA) statistical software.

Results unveil that the average impact of eco-innovation on SMEs` sustainable performance is positively significant but moderate. Moreover, it was found that eco-process, eco-product, eco-organizational, and eco-marketing innovations positively influence SMEs’ sustainable performance, but the impact of eco-organizational innovation is the strongest. Findings further reveal that eco-innovation positively influences economic, social, and environmental performance, but its effect on social performance is the largest. Moreover, our findings reveal that contextual factors, including industry type, culture, industry intensity, global sustainable competitive index, and human development index, moderate the eco-innovation/SMEs’ sustainable performance relationship. Lastly, methodological factors, namely sampling technique, study type, and publication status, account for study-study variance.

Our findings imply that investing in eco-innovation is worthwhile for SMEs. Therefore, CEOs/managers of SMEs must adopt eco-innovation initiatives by establishing a sustainability vision, developing employee environmental development and training, building a stakeholder management system, and promoting employee engagement in sustainability activities.

The study develops a holistic conceptual framework to consolidate the distinct types of eco-innovation and their association with the sustainable performance of SMEs for the first time in this research stream, thereby resolving the anecdotal results and synthesizing the fragmented literature across culture, discipline, and contexts.
