A new environment has evolved in the international stock markets, as expressed by the occurrence of market crises and high swings of stock prices. The stock prices are supposed to respond to real data under the market efficiency hypothesis. However, in some cases, price fluctuation is influenced by other conditions which may lead to a crisis. This paper discusses the issue based on the opinions of the stock market experts. The Amsterdam Stock Exchange (ASE) has been selected as a case for this research. The study indicates there is no significant difference among the perceptions of the three groups of ASE stock market experts concerning nine stated conditions which may lead to a stock market crisis, while significant differences exist among the ASE brokers, bankers and specialists concerning six stated elements that minimize the probability of evolving a stock market crises. There is a positive association among the groups of Amsterdam stock market experts about the total conditions that may lead to a stock market crisis, but there is no association concerning the total elements that minimize the probability of evolving a stock market crisis.

The purpose of this study is to analyze the relationship between country risk, stock prices and the exchange rate of the renminbi (RMB) compared to that of the US dollar.

An extended open macroeconomic model with investment–saving, liquidity preference–money supply and aggregate supply functions was used by applying comparative static analysis. After checking the series for stationarity and cointegration, a vector autoregressive model was applied. Lag length was selected based on the Akaike information criterion, and the coefficients were calculated for the overall sample and for pre- and post-July 2005 periods.

The stock market index is a significant determinant of variation in the exchange rate: when the Chinese stock market performs well, the RMB appreciates and vice versa. Country risk is not a significant determinant of the exchange rate, but the exchange rate of the RMB is a highly significant determinant of the country risk of China: depreciation of the RMB results in higher country risk and vice versa.

Linear interpolation was used to calculate the monthly values of some of the variables for which only annual data were available.

The authorities should revalue the exchange rate of the RMB against the US dollar, which will result in lower country risk for China. One way to achieve this is to strengthen the performance of stock markets.

To the best of the authors’ knowledge, this is the first study to explore the relationship between the country risk of China and the exchange rate of the RMB. Using an open macroeconomic model, this novel research analyzes the relationships between country risk, stock prices and the exchange rate of the RMB from a different perspective.

Foreign exchange exposure management has traditionally been viewed by corporate line management as a specialized and arcane corporate function. From its organizational position in Treasury or International Treasury, the function and the experts responsible for its execution, are frequently removed from the process of strategic planning and formulation of objectives. Foreign exchange experts are even less frequently consulted on matters of marketing and production investments and operation.

To expand understandings of conflict, this chapter offers a detailed assessment of how exchange is enacted within local heroin markets. Addressing drug dealing and heroin users’ buying drugs for their peers (i.e., brokering), this research expands how illegal drug markets are commonly understood. A generalized framework is presented that highlights patterns of exchange.

Findings come from a 36-month study of a demographically diverse sample of 38 heroin users in Cleveland, OH. Methods involved open-ended, semi-structured interviewing and participant observation, conducted by the author and a team of graduate students.

Instead of framing exchange as either an economic or social act, this chapter shows how trade in heroin markets is often both. Here Gudeman’s (2001) dialectic between market and community is embodied in inter-subjectivities of traders, promoting both trust and conflict. In this context, conflict is the result of perpetual ambiguity all market participants can experience.

Applying a blended notion of exchange as both social and economic offers new insight on conflict and expands its orientation beyond narratives of political economy. Here, in addition to the economics that often promote conflict, the social elements of exchange (e.g., reciprocity) are emphasized.

Research has understood conflicts in drug market operations through trader characteristics (e.g., poverty, race, class, privilege). This chapter emphasizes opportunities for conflict irrespective of individualized characteristics by outlining structural elements of exchange.

The 2007 BIS Triennial Central Bank Survey of Foreign Exchange and Derivatives Market Activity Report shows a substantial increase in turnover in foreign exchange and OTC derivatives markets. Turnover in traditional FX markets increased to reach $3.2 trillion. The largest contributor to this 71% increase between April 2004 and April 2007 occurred in FX swaps. It was like a prelude to the financial crisis of 2007–2008 driven by transactions carried out between banks and other financial institutions due to the significance of hedge funds and major engagement of emerging market currencies which have sought new configurations of portfolio diversification worldwide.

Purpose – The purpose of this essay is to explore further the concept of value cocreation from a service-ecosystems view, by considering the importance of networks and the configuration of relationships and resources in markets.

Methodology/approach – We use a conceptual approach to extend a service-dominant (S-D) logic, ecosystems view of value cocreation by drawing on the literature regarding networks in marketing and related research.

Findings – A service-ecosystems approach to cocreating value-in-context is proposed, which points toward networks as mediating factors in value cocreation because they influence the ability to access, adapt, and integrate resources by establishing exchange relationships and shaping the social contexts through which value is experienced.

Research implications – This research suggests that value cocreation is a complex and multidimensional process that is best studied in the context of dynamic networks or ecosystems of service exchange.

Practical implications – This research suggests that networks mediate value cocreation, and thus, firms should consider the configurations of relationships and resources to develop more compelling value propositions.

Social implications – This research draws on the idea that exchange relationships are embedded within society and suggests that processes of value cocreation not only draw on but also contribute to the social contexts that frame market exchange.

Originality/value of essay – This research extends the value cocreation and S-D logic literature by exploring the role of networks in service ecosystems. In this framework, networks are mediators of value cocreation because they enable access to resources and help to (re)shape social contexts through which value is derived.

The aim of this paper is threefold: (1) to develop a new measure of investor sentiment rational (ISR) of developing countries by applying principal component analysis (PCA), (2) to investigate co-movements between the ten developing stock markets, the sentiment investor's, exchange rates and geopolitical risk (GPR) during Russian invasion of Ukraine in 2022, (3) to explore the key factors that might affect exchange market and capital market before and mainly during Russia–Ukraine war period.

The wavelet approach and the multivariate wavelet coherence (MWC) are applied to detect the co-movements on daily data from August 2019 to December 2022. Value-at-risk (VaR) and conditional value-at-risk (CVaR) are used to assess the systemic risks of exchange rate market and stock market return in the developing market.

Results of this study reveal (1) strong interdependence between GPR, investor sentiment rational (ISR), stock market index and exchange rate in short- and long-terms in most countries, as inferred from (WTC) analysis. (2) There is evidence of strong short-term co-movements between ISR and exchange rates, with ISR leading. (3) Multivariate coherency shows strong contributions of ISR and GPR index to stock market index and exchange rate returns. The findings signal the attractiveness of the Vietnamese dong, Malaysian ringgits and Tunisian dinar as a hedge for currency portfolios against GPR. The authors detect a positive connectedness in the short term between all pairs of the variables analyzed in most countries. (4) Both foreign exchange and equity markets are exposed to higher levels of systemic risk in the period of the Russian invasion of Ukraine.

This study provides information that supports investors, regulators and executive managers in developing countries. The impact of sentiment investor with GPR intensified the co-movements of stocks market and exchange market during 2021–2022, which overlaps with period of the Russian invasion of Ukraine.

To explain an October 16, 2018 US Securities and Exchange Commission order that unanimously upheld a SIFMA challenge to fee increases for “depth-of-book” market data filed by Nasdaq and NYSE Arca and the SEC’s simultaneous remanding of over 400 market data fee and other filings back to the exchanges for consideration under the standards set out in the order.

Explains the criteria for fee increases under the Exchange Act, the SEC’s historic routine approval of exchanges’ proposed fee increases, the SEC’s challenge to two recent market data filings, and the SEC’s remanding of 400 additional market data fee filings challenged by SIFMA to the exchanges and the National Market System (NMS) for reconsideration. Analyzes and discusses the SEC’s order.

The SECs’ SIFMA order appears to raise the bar significantly for what exchanges must show to justify fee increases.More broadly, all five SEC Commissioners (of both parties) appear to be rethinking the role of for-profit exchanges in the regulatory structure.These orders have the potential to rewrite the regulation of market data, other exchange fees, and potentially the relationship between the exchanges and other market participants, for the entire securities industry.
