This study contributes to the pool of knowledge about the impact of monetary policy communication of central banks on financial instruments' prices and assets' value in emerging markets.

Empirical analysis is executed using the National Bank of Poland (NBP) announcements about its monetary policy covering the data from the broad financial market in its three main segments: stock market, foreign exchange market and bonds market. The reactions are measured relative to the changes in the NBP announcements and also with respect to investors' expectations. Autoregressive conditional heteroscedasticity (ARCH) models with dummy variables are used as the main methodological tool.

Bonds market and foreign exchange market are the most sensitive market segments, while interest rate and money supply are the most influential types of announcements. The changes of the revealed new macroeconomic figures had more impact on assets' prices movements than the deviations from their expectations. Moreover, greater diversity of the Monetary Policy Council (MPC) members' opinions on the voted motions, captured in the MPC voting reports, is associated with more cases of statistically significant NBP communication events.

The findings have direct relevance for fund managers, portfolio analysts, investors and also for financial market regulators.

The results provide novel evidence about how the emerging financial market responds to monetary policy announcements. They help understand the nature of the impact of public information on financial assets' valuation and on movements of their prices, analysed comprehensively in three market segments, in the emerging market environment.

This study examines the market reaction to the World Health Organization (WHO) announcement of the novel coronavirus disease 2019 (COVID-19) as a global pandemic on the emerging equity markets and compares the reaction with developed markets. This study also compares the market reactions to the COVID-19 pandemic with the market reactions to the 2008 global financial crisis.

Using the Morgan Stanley Capital International daily stock indices data and the Carhart and the GARCH(1,1) models for an event study, the authors examine the cumulative abnormal returns during 30 and 10 trading days and the extended 60 days before and after the WHO pandemic announcement. It also compares the market reactions during the COVID-19 pandemic with the reactions to the Lehman Brothers' bankruptcy announcement during the 2008 global financial crisis.

This study finds that the COVID-19 pandemic had a significantly greater negative impact to the stock markets in emerging countries than in the developed countries. The negative impact on the emerging markets is more pronounced for firms with small market capitalizations and for growth stocks. The negative impact of the COVID-19 pandemic is stronger in the energy and financial sectors in both emerging and developed markets. The positive impact of the COVID-19 pandemic occurred in healthcare and telecommunications for the emerging markets and information technology for the developed markets. This study also finds that the equity markets in both emerging and developed countries recovered faster from the COVID-19 pandemic relative to the 2008 global financial crisis.

Investors' desire to diversify their risks across different countries and sectors in the emerging markets could bring superior returns. The diversification strategies bring critical financial supports to forestall the contagion of COVID-19, to protect lives, and to save the emerging economies, especially for those financially constrained countries that are facing twin health and economic shocks by channeling their investments to countries with weak healthcare systems.

This study extends the literature that examines market reactions to stock market shocks by examining the market reactions to the COVID-19 outbreak on the emerging and developed equity markets across different market capitalizations, valuation and sectors. This study also finds that the markets recovered quicker from the COVID-19 pandemic announcement than during the 2008 global financial crisis.

The purpose of this paper is to compare the value creation of cross-border mergers and acquisitions (M&As) in mature and emerging markets.

The empirical study is based on a sample of 285 cross-border M&As announced between 2010 and 2012 and completed by companies of the French SBF 120 index in 54 countries.

The statistical analysis shows how financial markets react before and after the announcement of M&As. The obtained findings highlight significant differences: the reaction of financial markets before the announcement is moderately positive for M&As in mature economies, but negative for those in emerging economies; their reaction after the announcement is clearly positive for M&As in mature markets and moderately positive for those in emerging markets.

Future studies on M&A value creation should differentiate mature and emerging economies and adopt a more in-depth classification of target countries.

This research emphasizes the necessity to consider country-specific factors for M&A value creation.

The empirical study is based on a sample of French acquirers, who account for 3 percent of the volume and value of M&As in the world and whose operations are rarely studied in the literature. The authors compare the reaction of financial markets before and after the announcement of M&As conducted in mature and emerging economies.

This paper aims to determine whether audit opinions in Morocco, an emerging market, are value relevant to the stock market, through the investigation of the market reaction to the issuance of modified audit opinions (MAOs).

The event study approach is used. The data are derived from the financial reports of listed companies on the Casablanca Stock Exchange over a period of 10 years from 2010 to 2019.

This paper does not find evidence that the market reacts to the issuance of MAOs when grouped together. When partitioning the sample by types, there is an evidence of a stock market reaction to qualified audit opinions and the qualified audit opinions with observation paragraph when they are combined with a negative variation of earnings per share. Examination of the impact of different natures of qualifications shows no consistent results and that the market does not distinguish between natures of qualifications.

These results may be due to the fact that some investors have information about the audit opinion long before it is made public, due to privileged access to audit opinions, or that investors underestimate audit opinions relative to other financial indicators.

This study contributes to the existing literature by investigating an emerging market, not previously tested, after the introduction of several regulatory reforms in Moroccan market aimed at enhancing transparency in financial reporting. It refines the market reaction models used in previous studies by using both ordinary least squares and the Scholes–Williams techniques that correct for the effect of thin trading on the market index. In addition, special attention is given to studying the market reaction to each type of MAOs and to each natures of qualifications.

The current paper aims to expand an empirical assessment of correlations of the stock exchange in Poland with other stock markets and foreign economies. The paper attempts to explore international spillover effects during the current financial crisis.

The study builds upon questionnaires and interviews with practitioners associated with the Polish stock market. The interviewees represent both the advanced and emerging European economies. At this point, analyzing the notions of a cross‐section of experts from different geographical regions increases the value of the findings. The interviewees were asked to comment on a wide range of examples mirroring the reaction of the Warsaw Stock Exchange (WSE) to economic and financial information derived from foreign markets in times of the current financial crisis. An empirical model evaluating the cross‐border implications for the Polish stock market was specified. The model encompassed a wide range of variables and events influencing the performance of the Polish stock market and investors' uncertainty during the nascent financial crisis. Semi‐structured interviews complemented the quantitatively obtained findings and allowed for a gap between theory and practice to be bridged. The qualitative approach injected a dose of realism into the empirical model utilized in the paper and contributed to the value of general findings.

The current paper reports initial responses of the WIG20 indexed equity prices to 41 economic and financial information sets, originating from systemically significant markets. The influence of these sets is ranked in accordance with their influential powers. The ranking indicates which information events are more likely to be prioritized by investors associated with the WSE and which news are ignored in times of the current financial crisis. Henceforth, the findings outline the crisis‐induced changes in the uncertainty of equity investors and the implications for investment decision making processes. Comparing the responses to economic and financial information sets among different stock markets and industries delivers insight into the profitability of the international portfolio diversification based on either the country or industry specific factors.

The paper focuses on the Polish stock market, which is relatively under‐researched by the existing body of literate. However, Poland's stock market became a leading central European bourse during the current financial crisis. Reporting a number of useful and important implications for the practitioners associated with the WSE constitutes the core value of the paper.

This study examines whether investors value the timing and/or information of mandatory disclosures in a unique research setting of listed companies in Thailand.

The authors adopt an event-study based approach. Abnormal stock returns are calculated using an OLS market model to measure market reactions to three types of mandatory reports issued by listed Thai firms: financial statements, Form 56-1 and Form 56-2. These reports are released sequentially but contain overlapping information content. Multivariate regression models are employed to examine the market reactions to these regulatory reports and explore the characteristics of firms that affect the market response.

The stock market reacts differentially to these reports. The financial statements, which are filed the earliest and are the most concise, prompt the strongest reaction. Investors similarly react significantly to Form 56-1 and Form 56-2, although Form 56-2 provides additional information beyond Form 56-1. The market reactions to small firms are stronger. Collectively, equity investors focus on the timeliness of disclosures rather than the information disclosed in the mandatory reports.

The evidence provides support for ongoing regulatory initiatives aimed at improving the timeliness of mandatory disclosures in emerging economies.

Prior studies on disclosure regulation investigate either the effect of information content or the timing of mandatory disclosures in isolation. The authors differentiate the effect of information content from disclosure timing and extend the literature by suggesting that investors incrementally value timeliness of disclosures. Investors perceive the benefit of the timely release of quantitative information compared to subsequent narrative disclosures. Between Form 56-1 and Form 56-2, the earlier release of the narrative non-financial information is incrementally traded into share prices.

The objective of this study aims at reviewing a synthesis of the economic impact of the implementation of International Financial Reporting Standards (IFRS) in an attempt to provide directions for future research. There are significant evidences of adopting a high-quality set of harmonised accounting standards (i.e. IFRS) fosters trade and foreign direct investment (FDI), financial transparency, and comparability and reduces information asymmetries. From the extensive structured review of literature using the Scopus database tool, the study reviewed 108 articles, and in particular, the topic-related 41 articles were analysed. Seven journals contribute to 39% of the articles (The Accounting Review; European Accounting Review; International Journal of Accounting; Journal of Accounting Research; Revista Espanola de Financiacion y Contabilidad; Asian Review of Accounting; and International Journal of Economics and Management). However, most of the cited journals were Journal of Accounting Research, The Accounting Review, European Accounting Review, and International Journal of Accounting (Armstrong, Barth, Jagolinzer, & Riedl, 2010; Brüggemann, Hitz, & Sellhorn, 2013; Christensen, Lee, & Walker, 2007; Daske, Hail, Leuz, & Verdi, 2008, 2013). Most of the studies did not use any theory, and most of the articles utilised quantitative approach. The study calls for future research on the theoretical impactions on the economic impact of IFRS implementation in a country-specific study, cross-country study, and global study. Future studies should also focus on the policymaking agenda for the local and international standard setters.

This study aims to investigate the market reaction to the Russian invasion of Ukraine, specifically in the banking sector.

The research uses an event study and cross-sectional analysis, with market reaction measured by cumulative abnormal return (CAR). The sample comprised 1,126 banks.

The results show that the market reacted negatively to the invasion both before and after its announcement. Developed and emerging markets saw a negative impact from the invasion, while frontier markets experienced only a slight impact. The authors also find that the banking markets of North Atlantic Treaty Organization (NATO) members reacted significantly and negatively both before and after the invasion was announced. This demonstrates that the negative market reaction of NATO members was more impactful than that of other markets. Overall, this study shows that investors in the banking market are very sensitive to war.

This is the first study to provide international evidence, specifically on the banking sector's reaction during the Russian invasion of Ukraine.

The purpose of this paper is to analyse the market reaction to the appointments of chief executive officers (CEOs) in companies listed on the Warsaw Stock Exchange. The authors focussed on the relationship between the characteristics of a newly appointed CEO and the shareholders’ reactions to the appointment of a CEO.

To measure shareholder reaction, the authors apply an event study methodology. The determinants of reaction are identified on the basis of multi-regression analysis.

The results reveal a negative market reaction to all CEO appointments, both new appointments and reappointments. Investor reaction is driven more by the financial condition of the company, the company’s market performance and the free float, than by the characteristics of a newly appointed CEO. Neither the origins and generation (age) nor the gender of a CEO influence share prices. The relationship between the educational background of a CEO and shareholders’ reactions is mixed. Furthermore, the appointment of an inexperienced CEO seems to be preferred by investors.

The study is restricted by certain limitations related to the adopted measures, the single-market research, data gaps and the selection of variables for regression analysis. A further cross-country study including Central and Eastern Europe and/or the transition economies of the Baltic Region is recommended. The relationship between the operating performance of a firm and its internal control mechanisms could be explored.

The findings might influence the decisions made by company owners and supervisory boards when appointing top executives, and might contribute to a better understanding of how CEO appointments can affect shareholder value creation. The results also provide important guidelines for institutions that oversee the financial system.

The findings of this study are expected to the findings are expected to contribute to the literature on the empirical analysis of the shareholder wealth effect, on signalling theory, on the phenomenon of information asymmetry and on corporate governance. The study covers a full economic cycle of the capital market, including the financial crisis and financial bubbles, and it fills a gap in the research regarding emerging markets and transition economies in Europe.
