Exchange Rate Changes

Purpose This paper aims to empirically investigate the volatility of Bitcoin, Litecoin and the Euro. Design/methodology/approach The authors use quantitative methodologies to assess the annualized volatility of two cryptocurrencies and one international fiat currency. The exchange rate of the currencies is monitored on a daily basis using 1,460 observations from January 1, 2014 to December 31, 2017. The models used include the augmented Dickey–Fuller test, Akaike Information Criteria, autocorrelation function and exchange rate changes determining which currency is the most volatile. Findings The findings indicate, based on the statistical measures used, including the standard deviation of selected currencies and annualized volatility, that Litecoin is more volatile than Bitcoin and the Euro and that Bitcoin is more volatile than the Euro. This furthers previous research on cryptocurrency volatility. Originality/value The paper provides compelling evidence about the volatility of Litecoin and Bitcoin. The volatility of cryptocurrencies is furthered with data that are more current. The findings are important for investors, financial markets and central banks.

Exchange Rate Changes

Purpose The purpose of this paper is to assess asymmetric effects of exchange rate changes on Thailand’s trade balances. Design/methodology/approach The design methodology is based on the nonlinear ARDL approach of Shin et al. (2014). Findings The authors find strong support for the asymmetric effects of exchange rate changes on the Thailand trade balance with most partners, including the three largest partners, China, Japan and the USA. Research limitations/implications The long-run asymmetric effects revealed that while baht depreciation will hurt Thailand’s trade balance with China, it will improve its trade balance with the USA and has no effects with Japan. Practical implications The trade balance of different partners reacts differently to currency depreciation. Social implications A currency depreciation that improves the trade balance by promoting exports also helps to reduce the rate of unemployment. Originality/value No study has assessed the asymmetric effects of exchange rate changes on the Thailand’s trade balance with its major partners.

Purpose Reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The problem with developing a reputation of being something of an oracle in the business world is that all of a sudden, everyone expects you to pull off the trick of interpreting the future on a daily basis. Like a freak show circus act or one-hit wonder pop singer, people expect you to perform when they see you, and they expect you to perform the thing that made you famous, even if it is the one thing in the world you don’t want to do. And when you fail to deliver on these heightened expectations, you are dismissed as a one trick pony, however good that trick is in the first place. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose – This article aims to provide insight into the future of financial markets and regulation in order to define what would be the best strategy for Europe. Design/methodology/approach – First the authors define the potential changes in financial markets and then the tools available for the regulator to tame them. Finally, they build five scenarios according to the main evolutions observed on the financial markets and on the tools used by the regulator to modify these trends. Findings – Among the five scenarios defined, two present highly unstable features since the regulator refuses to choose between financial opening and independently determining how to regulate finance in order to preserve financial stability. Three of them achieve financial stability. However, they are more or less efficient or feasible. In terms of market efficiency, the multi-polar scenario is the best and the fragmentation scenario is the worst, since gains of integration depend on the size of the new capital market. Regarding sovereignty of regulation, fragmentation is the best scenario and the multi-polar scenario is the worst, because it necessitates coordination at the global level which implies moving further away from respective national preferences. However, the more realistic option seems to be the regionalisation scenario: this level of coordination seems much more realistic than the global one; the market should be of sufficient size to enjoy substantial benefits of integration. Nevertheless, the “European government” might gradually increase the degree of financial integration outside Europe in line with the degree of cooperation with the rest of the world. Originality/value – Foresight studies on financial markets and regulation are quite rare. This may be explained by the difficulty to forecast what will be their evolution in the coming decades, not least because finance is fundamentally unstable. This paper provides a framework to consider what could be the best strategy of regulators in such an unstable environment.

Purpose This paper aims to assess auditor narcissism’s effect on audit market competition (auditor concentration, clients’ concentration and competitive pressure). Design/methodology/approach This paper’s method is descriptive-correlational based on published information from listed firms on the Tehran Stock Exchange from 2012 to 2018 using a sample of 188 firms (1,310 observations). The method used for hypothesis testing is linear regression using panel data. Findings The results show a negative and significant relationship between auditor narcissism and audit market competition and its indices, including auditor concentration, clients’ concentration and competitive pressure. Moreover, a positive and significant relationship was observed between audit quality and audit market competition and its indices, including auditor concentration, client concentration and competitive pressure. Originality/value To analyzes competition indices in the audit market (auditor concentration, clients’ concentration and competitive pressure). The variable is assessed once more using the exploratory factor analysis of the so-called three variables single variable, named audit market competition. So the central question of the study is investigated within a broader sense. Moreover, as the present study is carried out in the emergent financial markets with extremely competitive audit markets to figure out the effect of auditors’ intrinsic characteristics on such markets’ competitiveness, it can provide useful information in this field.

Purpose The efficient market hypothesis (EMH) states that asset prices in financial markets always reflect all available information about economic fundamentals. The purpose of this paper is to provide a guide as to which predictions of the EMH seem to be borne out by empirical evidence. Design/methodology/approach Rather than following the classic three groups of tests for the different forms of EMH that are common in the literature, the authors consider how the two alternative definitions of the EMH and the joint hypothesis problem impact on the tests and leave the controversy unsolved. The authors briefly report the antecedents, the main theoretical and empirical contributions and recent literature on each type of tests. Findings Eventually, as a summary for each type of tests, the authors provide a critical view on the main sources of acrimony between the alternative schools of thought in understanding asset price formation. Originality/value The paper may be seen as an up-to-date introductory review for researchers on the different tests of the EMH performed, and for newcomers to understand the key sources of acrimony between rationalists and behaviorists.

PurposeThe purpose of this paper is to investigate whether there are information leaks immediately before CEOs change and – if so – whether some investors take financial advantage of such prior knowledge. It thirdly investigates the ethical, practical and professional options for communication managers to deal with such situations.Design/methodology/approachWorking from sentiment theory of financial markets, the authors studied Internet search patterns for incoming CEO names and stock market movements immediately prior to the public mention or speculation of CEO change.FindingsThe authors find that in nearly a quarter of CEO changes at Fortune 500 companies, the name of the future CEO seems to have been leaked. Additionally, nearly half of those companies also experience extreme, otherwise unexplainable movements in the stock market.Originality/valueThis paper discovers the prevalence of extreme stock market movements for a company when the name of that company's next CEO has likely been leaked. Such leaks are an opportunity for unscrupulous investors, but they create ethical dilemmas for organizations. Communication managers typically respond by organizing tighter governance. However, to keep up with the speed of information and investments traveling through algorithms, organizing radical transparency could become an alternative instead.

Exchange Rate Changes

Purpose This study focuses on Egypt’s recent experience with exchange rate policies, examining the existence of spillover effects of exchange rate variations on stock prices across two different de facto regimes and whether these effects, if any, are asymmetric. Design/methodology/approach The empirical analysis is carried out using a nonlinear autoregressive distributed lag modeling framework, which permits testing for the presence of short- and long-run asymmetries. Relevant local and global factors are also included in the analysis as control variables. The authors divide the entire sample into a soft peg period and a free float one. Findings Over the soft peg regime period, both positive and negative changes in EGP/USD exchange rates seem to have a significant impact on stock returns, whether in the short or long run. Short-term asymmetric effects vanish in the free float period, while long-term asymmetries continue to exist. By and large, the authors find that currency depreciation tends to exercise a stronger influence on stock returns than does currency appreciation. Practical implications The results offer important insights for investors, regulators and policymakers. With the domestic currency depreciation having a negative impact on stock prices, investors should contemplate implementing appropriate currency hedging strategies to abate depreciation risks and, hence, preserve their expected rate of return on the Egyptian pound-denominated investments. In the current post-flotation era, the government could pursue a flexible inflation targeting monetary policy framework, with a view to both lowering the soaring inflation toward an announced target rate and stabilizing economic growth. The Central Bank of Egypt (CBE) could adopt indirect monetary policy instruments to secure tightened liquidity conditions. Besides, the CBE could raise policy rates to incentivize people to keep their money in local currency-denominated instruments, instead of dollarizing their savings, thereby relieving banks of foreign currency demand pressures. Nevertheless, while being beneficial to the country’s real economy on several aspects, such contractionary monetary measures may temporarily impinge on stock market performance. Accordingly, policymakers should consider precautionary measures that reduce the potential for price distortions and unnecessary volatility in the stock market. Originality/value To the best of the authors’ knowledge, the current study represents the first attempt to explore the potential impact of exchange rate changes under different regimes on Egypt’s stock market, thus contributing to the relevant research in this area.

Purpose This paper aims to provide a novel way of thinking about firm internationalization. We offer a stylized view of family firms as internationalizers who choose to engage in “boundary-spanning” across global product markets while engaging in “boundary-buffering” to insulate themselves from global financial markets. Design/methodology/approach The case of Germany, with its large stock of internationalized family firms, shows how boundary-buffering vis-à-vis global capital markets can be compatible with successful and sustained internationalization and boundary-spanning in global product markets. Statistics are supplied. Findings To compensate for the lack of resources stemming from their abstinence from global financial markets, German family firms draw on country-specific conditions favorable to the proliferation of large internationalized family firms. Insights from the German case serve to derive propositions. Originality/value The developed concept of an internationalization pathway for family firms contrasts with the much more established concept of an internationalization process for family firms. The contrast between a “pathway” and a “process” amounts to the distinction between ends and means: the internationalization pathway (as defined here) has largely to do with strategic choice, whereas the internationalization process (as defined in the literature) focuses more on barriers to internationalization and means for overcoming them.

Purpose This paper aims to discuss the topic of financial speculation with special reference to forex and offers an analysis from the Maqasid Al-Shari’ah perspective, whereby authors propose to limit the outreach of speculative instruments in the financial markets. Design/methodology/approach The authors will make use of a simple textual analysis of existing materials and documents. To come up with conclusions, relevant to this study and to make them credible enough, the authors will undertake to review the existing literature in the next part of the paper and will later present his analysis of findings in light of financial crises and the objectives of Shari’ah. Findings The Maqasid Al-Shari’ah approach used in the analysis suggests that speculative financial instruments do not constitute a necessity, and their harmful practice must be limited to protect the religion, life, lineage, intellect and property. Originality/value Financial speculation in general and foreign exchange in particular must be regulated. Their current practices of financial system pose significant challenges for entire economies as well as individuals. Muslims should also avoid speculative financial instruments, such as forex, because they are a clear threat to individual and state wealth and prosperity. In addition, they threaten traditional businesses and social norms in Muslim societies.

Practical Implications

PurposeThe purpose of this paper is to try and trace a new itinerary in the matter of the destabilization of financial institutions, i.e. the identification of a catalogue of measures that private law can offer in order to make sure that all unlawful initiatives resulting in the loss of credibility of financial markets and prejudice to the public at large do not escape the imposition of all possible liabilities.Design/methodology/approachThe matter here applied consists of the recourse to a number of experiences deriving from European legal systems that have tackled the phenomenon of unlawful attacks on the integrity of the financial markets through individual or organized acts. This comparative approach also benefits from the scrutiny of both legislation and judicial decisions: the latter are also looked at from the perspective of legal authors.FindingsThe most striking result of the research is that the instruments provided for by the private law remedies seem to be very efficient in the contrast of unlawful practices adversely affecting financial markets: the new spirit emerging from this survey is that it is imperative to set aside all contracts and agreements aimed at creating illicit ways to make profits and hide their origins.Practical implicationsThe practical implication should be to encourage all institutions with the task of checking the good functioning of financial markets to avail themselves of the tools here described to stabilize markets and deprive illegal contracts of their ill effects: it would be most desirable if such an approach were to be taken.Originality/valueThe novelty lies in the new approach described above (practical implications).
