This study aims to analyse the effects of Economic Policy Uncertainty (EPU) on the return of growth/value and small/large-cap stocks during expansionary and recessionary periods across a conditional distribution.

The authors selected a sample covering the period between 01/1995–05/2021. Quantile regressions were applied to the EPU and Russell indices. Business cycles were established following the NBER.

The results show that EPU has a negative effect on stocks with the intensity of the effect depending on the stock's profile. Small-cap and growth stocks were found to be most sensitive to EPU, especially during recessions. The negative effect is moderated by the economic cycle but is progressively diluted at the lower tail of the stock return distribution.

The findings shed more light on investment strategies for growth/value investors that pursue opportunities arising from a changing economic cycle.

This study makes the following contributions: (1) explores the impact of EPU on the return of different stocks across a conditional distribution, and (2) provides evidence on how the economic cycle influences EPU impact on growth/value stocks and small/large stocks.

:本研究擬分析跨條件分佈、以及於擴張期和衰退期,經濟政策不確定性對成長型股票/價值股和小盤股/大型股的收益的影響。

我們選擇了涵蓋1995年1月與2021年5月期間的樣本進行研究。我們於經濟政策不確定性指數和羅素指數上採用分位數迴歸法進行研究; 並跟隨著美國國家經濟研究局,建立了多個經濟週期。

研究結果顯示,經濟政策不確定性對股票是有負面影響的,而影響的強度則視乎股票的投資組合而定。我們發現,小盤股和成長型股票對經濟政策不確定性是非常敏感的,尤其是在經濟衰退期間。這負面影響會被經濟週期緩和,唯這緩和作用卻會在股票收益的低尾處逐漸減輕。

研究結果使我們更容易理解為尋找因經濟週期改變而衍生的機會的增長/價值投資者所提供的投資策略。

本研究有以下的貢獻:(一) 、 探究了經濟政策不確定性對跨條件分佈、不同的股票收益的影響; (二) 、為經濟週期會如何左右經濟政策不確定性對成長型股票/價值股和小盤股/大型股的影響,提供了證據。

The goal of this work is to determine whether Bitcoin behaves as a safe-haven asset. In order to do so, the influence of Economic Policy Uncertainty (EPU) on Bitcoin returns and volatility was studied.

It is evaluated whether, when compared with the evolution of EPU, Bitcoin's returns and volatility show behaviours typical of safe havens or rather, those of conventional speculative assets. When faced with an increase in EPU, safe havens – such as gold – can be expected to increase their returns and volatility, while conventional speculative assets will increase their volatility and reduce their returns. This study uses simple linear regression and quantile regression models on a daily data sample from 19 July 2010 to 11 April 2019, to analyse the influence of EPU on the returns and volatility of Bitcoin and gold.

Bitcoin's returns and volatility increase during more uncertain times, just like gold, showing that Bitcoin acts not only as a means of exchange but also shows characteristics of investment assets, specifically of safe havens. These findings provide useful information to investors by allowing Bitcoin to be considered as a tool to protect savings in times of economic uncertainty and to diversify portfolios.

This study complements and expands current research by aiming to answer the question of whether Bitcoin is a simple speculative asset or a safe haven. The most significant contribution is to show that Bitcoin is not a mere speculative asset but behaves like a safe haven.

本研究旨在確定比特幣是不是避難所資產。為達這目的，研究人員探討了經濟政策不確定性對比特幣的回報及波動性的影響。

研究評估比特幣的回報和波動性，若與經濟政策不確定的進化作比較，會顯示資金避難所的典型行為，抑或顯示傳統投機資產的行為。當面對經濟政策不確定的增加時，資金避難所 - 如黃金－會被預期有回報及波動性的上升。但傳統投機資產則其波動性會增加及其回報會減少。本研究使用簡單線性迴歸及分位數迴歸模型，根據從2010年7月19曰至2019年4月11日期間每天的數據樣本，來分析經濟政策不確定對比特幣和黃金的回報及波動性所產生的影響。

像黃金一樣，在較不明朗的時期，比特幣的回報和波動會增加，這顯示比特幣不單是一個交易工具，它也表現投資資產的特性，特別是資金避難所的特性。這研究結果為投資者提供有用的資訊，讓他們在經濟不明朗時考慮以比特幣作為保障存款的工具，及以比特幣作為使其投資組合更多元化的工具。

本研究旨在探索比特幣是一簡單的投機資產、抑或是一資金避難所，這補足及擴展了目前的研究。本研究最重要的貢獻、在於顯示了比特幣不單純是一種投機資產，它的行為實像資金避難所一樣。

This paper aims to examine the impact that monetary policy uncertainty (MPU) has on stock market returns by taking into account limits to arbitrage and the economic cycle.

Using four news-based MPU measures, regression models have been applied in this study over a sample period from January 1985 to March 2020. The limits to arbitrage have been considered by taking Russell 1000 Value, Russell 1000 Growth, Russell 2000 Value and Russell 2000 Growth indices, and business cycles were established following the National Bureau of Economic Research.

A negative MPU impact on stock returns has been found. In particular, the most subjective and difficult to arbitrate stocks have been more sensitive to MPU. However, it could not be concluded that MPU has a greater or lesser impact on stock returns depending on the economic cycle.

The findings obtained are particularly useful for monetary policymakers showing the importance and need for greater control over the transparency of their decisions to maintain the stability of financial markets. The findings obtained are also useful for investors when selecting their investment assets at times of the highest MPU.

To the best of the authors’ knowledge, this is one of the few studies investigating the effect of MPU on stock market returns, and the first to analyse this relationship taking into account the economic cycle and limits to arbitrage.

This paper aims to evaluate the influence of economic policy uncertainty (EPU) on the momentum effect, analysing its influence depending on the economic cycle and in different quantiles.

To determine the influence of EPU in the momentum effect taking into account the economic cycle and the level of the quantile, linear regression and quantile regression have been applied for the period from 2 January 1985 to 30 April 2019 for the US stock market.

It is shown that an increased feeling of insecurity associated with EPU reduces the momentum effect, especially in times of recession. Distinguishing by quantiles, an asymmetry in the impact of EPU in the momentum effect is discovered, finding that EPU reduces (increases) the profits of momentum strategies in the lowest (highest) quantiles. In the highest quantiles, an investor can obtain higher extraordinary returns with this strategy. For example, in the highest quantile, a one-point increase in the EPU levels would have increased the daily profitability by 12.7 basis points. These findings have important implications for investors and policymakers.

To the best of the authors’ knowledge, this is the first paper that evaluates the influence of EPU on the momentum effect by conducting an analysis based on the economic cycle and different quantiles, demonstrating how these factors are relevant in the influence of this uncertainty in the momentum anomaly.

Academic literature calls for research on the impact of psychological states derived from mental illness on detrimental consumer behaviour. The purpose of this study is to assess the impact of anxiety on the consumer’s buying processes (compulsive and impulsive) and emotional regulation.

To carry out the statistical analysis, the data were obtained through an online survey (n = 726) of supermarket consumers. The treatment of the data was using partial least squares structural equation modelling (PLS-SEM).

The results obtained show that anxiety influences the generation of harmful behaviour, as it has a positive impact on compulsive and impulsive buying. In addition, compulsive and impulsive buying generate higher levels of consumers’ emotional regulation.

This study contributes to the management of anxiety as a priority element to reduce harmful behaviour. Therefore, it provides useful information for marketing managers and professionals in psychological and healthy consumer processes.

學術文獻不斷呼籲研究人員和學者去探討來自精神病的心理狀態如何產生有害的消費者行為。本研究擬評定焦慮對消費者購買流程 (強迫性購物和衝動購物) 和情緒調節所產生的影響。

為能進行統計分析,研究人員透過超級市場消費者的在線調查 (n = 726) 取得數據,繼而以結構方程 (PLS-SEM) 處理數據。

研究結果顯示,焦慮會導致有害行為的產生,這是因為焦慮對強迫性購物和衝動購物均產生積極的影響; 而且,強迫性購物和衝動購物會產生較高水平的消費者情緒調節。

本研究的貢獻在於把焦慮視為減少有害行為的優先元素而予以管理; 因此,本研究為市場經理以及於心理上的和健康的消費者進程的專業人員提供了有用的資料。

The main objective of this study is to identify some of the variables that affect the perception of Brazil country brand, as well as the knowledge of the relationships between them.

The proposed model aims to find out the influence of the affective image, the cognitive image, the identity and the reputation on the country brand. Partial Least Squares (PLS) is the method used to test the proposed model.

According to the results obtained, it seems that both identity and reputation have a positive and significant effect on the country brand. On the other hand, the cognitive image is positively related to identity and the affective image, while it is surprising that the affective image itself shows no significant influence on identity.

The study is of particular interest to the policy makers of territories, explaining the factors they must influence in order to successfully enhance the country brand. It also contributes to theoretical development by proposing a conceptual model that highlights the importance of the cognitive image in the country brand, due to its effect on the affective image and identity.

El principal objetivo de este estudio es identificar algunas de las variables que inciden en la percepción de la marca país Brasil, así como el conocimiento de las relaciones entre ellos.

El modelo propuesto tiene como objetivo conocer la influencia de la imagen afectiva, la imagen cognitiva, la identidad y reputación en la marca país. El PLS (Partial Least Squares) es el método utilizado para probar el modelo propuesto.

Según los resultados obtenidos, parece que tanto la identidad como la reputación tienen un efecto positivo y significativo en la marca país. Por otro lado, la imagen cognitiva se relaciona positivamente con la identidad y la imagen afectiva, mientras que sorprende que la imagen afectiva en sí misma no muestra una influencia significativa sobre la identidad.

El estudio es de especial interés para los responsables políticos, ya que explica los factores que debe influir para potenciar con éxito la marca país. También contribuye al desarrollo teórico proponiendo un modelo conceptual que resalte la importancia de la imagen cognitiva en la marca país, por su efecto sobre la imagen e identidad afectiva.

The purpose of this paper is to clarify and extend knowledge concerning the relationship between legitimacy and organizational success within the framework of institutional theory.

While previous research has found links between legitimacy and organizational success, the authors test this assumption by case analysis, on a sample of thirteen Spanish Mutual Guarantee Societies. Data were collected from survey questionnaire and Annual Financial Reports.

Results of the empirical examination confirm that, within this population, organizations with greater legitimacy obtain better organizational results as well as improved access to resources. The findings also show that not all dimensions of legitimacy contribute equally to organizational success.

For managers, the authors have included a recommendation that legitimacy is an important element of an organization's success that must be strategically managed and be considered as a required goal in the organization's strategic planning process. Managers should analyze legitimacy, in their own activity sector, to identify the most useful types of legitimacy. In the specific case of Spanish MGSs, the most beneficial strategic actions are those geared towards obtaining pragmatic legitimacy.

The analysis provides a new approach to measure legitimacy. It also provides empirical advances to the organizational legitimacy process, showing its usefulness as a key factor for organizational success.

Foreign markets possess different characteristics to domestic ones; this means that dynamic marketing capabilities (DMCs) should be adjusted. This paper aims to understand how these DMCs enable firms to achieve greater legitimacy in international markets.

This research uses a qualitative approach based on in-depth interviews in collaboration with an association of exporting firms.

Findings suggest five areas of DMCs to improve organizational legitimacy overseas: flexibility, relationship management, local market sensitivity, anticipation and exemplariness. Those capabilities should be combined and will play a different role depending on the implementation phase of the external company. Resource allocation and capability development should follow an integrative approach emphasizing proximity, adaptability, alliances, engagement and credibility to reach differentiation in foreign markets.

The originality is mainly focused on the cohabitation and strong synergies between DMCs and legitimacy. This aspect is particularly relevant because legitimized companies have higher levels of survival, which is fundamental in the international venture.

The aim of this paper is to measure the effects of universities' ethical management and positive impact on society affect the faculty engagement through the mediating effect of organizational legitimacy.

Engaged employees are characterized by better performance, increased productivity and by generating higher customer loyalty as well greater economic profit. The commitment to the organization they work for is affected by internal and external inputs. Among these, business ethics and corporate community outreach are key factors for improving employee engagement. The authors developed a survey that was distributed to professors of Spanish universities. To treat the data and test the proposed hypotheses, the authors applied structural equations through PLS-SEM.

This research contributes to the organizational management field literature and advises university administrators to adopt an ethical management style based on information transparency, accountability and faculty member involvement in the decision-making process in order to improve their engagement and, therefore, increasing student satisfaction, academic results and positive impact on the common good.

The novelty of the authors’ research stands in the inclusion of legitimacy as a mediation effect between business ethics and community outreach that affect employees' engagement and, specifically, faculty engagement.
