Despite the great amount of attention to emerging markets, much still remains unknown about firm performance in emerging economies. To fill this gap, this study aims to investigate factors that influence labor productivity of firms in Brazil, China, India, and Russia (BRIC countries). This study focuses on features of business environments of emerging markets such as informality, corruption, foreign ownership, and external audit. Using a cross-national sample of 8,885 firms from the World Bank Enterprise Surveys dataset, we find that informality is negatively associated with labor productivity, while corruption and external audit are positively related to labor productivity. Implications will be discussed.

The textile industry of the City of Tshwane has been overwhelmed by cheap imports from countries such as China, India, Pakistan, Bangladesh, Malaysia, South Korea and Vietnam. Although support is provided to black entrepreneurs in the textile industry of Tshwane by institutions such as the South African National Department of Trade and Industry and the South African Small Enterprise Development Agency, local textile businesses are unable to compete favourably with foreign manufacturers, importers and distributors. The textile industry is a key contributor to the South African GDP and employs about 5% of the South African workforce. One of the key priorities of the City of Tshwane is to transform the textile industry of Tshwane so that it provides sustainable livelihood and career opportunities to black indigenous South Africans. A descriptive, cross-sectional study design was used for collecting data from a stratified random sample of size 250 textile businesses operating in the five geographical zones of Tshwane. One of the aims of the study was to assess the veracity of the theory proposed by Bansal and DesJardine (2014) in which the authors have argued that changing global circumstances would compel local industries to adapt to global changes at local level as a means of sustained survival. Data analysis was performed by using Structural Equations Modelling (SEM). The results showed that sustained viability in textile businesses was significantly influenced by the degree of entrepreneurial skills, the ability to secure loan needed for operation, and the ability to order merchandise in bulk on credit from suppliers, in a decreasing order of strength. About 32% of business operators had adequate entrepreneurial skills based on the composite index developed by Acs, Szerb and Autio (2011). A repeat of the same study as a 5-yearlong study is recommended in order to estimate theoretically reliable predictors such as hazard ratios for factors that are known to affect viability in the local textile industry.

As the e-commerce market evolves from being primarily transactional to being more subtle, sellers now seek to form online strategies. Previous studies have investigated buyers’ purchasing patterns, online transaction trust, electronic word-of-mouth, online resale behavior as well as online auctions. However, less is known about the antecedents that effect store traffic and sales. By using real market data from a major Chinese C2C e-commerce site, this article investigates C2C transactional formation and identifies sellers’ performance payoffs that result from various marketing factors. Marketing factors that influence store traffic and sales will be analyzed by means of the Negative Binomial model and Tobit model. Results point out that strong store reputation and high service quality are crucial indicators for increasing number of browsers and sales amount. In accordance with the results of prior research, advertising is confirmed as an effective tool for positively influencing both store traffic and sales. In addition, we found that guarantee policies can positively impact store sales only by interacting with reputation ratings. Drawing on empirical findings, we also discuss the managerial implications for C2C sellers and put forth some recommendations.

This study examines the relation between cost asymmetry and stock option grants. I posit that managers’ incentives to decrease the strike price of subsequent option awards may affect manager’s resource adjustment decisions. Using U.S. firm data, I find that the degree of SG&A (selling, general, and administrative) cost asymmetry is positively related to the value of subsequent option grants awarded to the CEOs, suggesting that managers who expect large stock-option grants deliberately delay reduction of committed costs to decrease the share price prior to the option award date. Manipulating the timing of stock option grants do not fully explain the results because the positive relation that this paper documents still holds with only fixed-date option awards sample.

This paper systematically elaborates the theory of productivity in consumption society, the mainstay theory in Dr. Bingxin Wu’s (Wu, 1997, 2008, 2011, 2013, 2015 & 2017) comprehensive consumption theoretical system. An analysis on history and current academic situation of the western consumption theory is employed to explore the defects and shortages of the existing consumption theory. The emphasis of the paper is on the academic significance and practical significance of the consumption society productivity. The paper also explains in detail the practical importance of productivity theory in guiding consumption society and provides evidences discovered from the continuous rapid development of the Chinese economy.

Measuring risk is the key component in many asset pricing models. Although volatility is the most widely used measure for the risk, Value at Risk (VaR) and Maximum drawdown (MDD) are also considered as alternative risk measure. This article questions whether VaR and MDD contain additional information to volatility in equity market. The empirical analysis is conducted using the stocks listed in Korean stock market. By constructing portfolios in accordance with three risk measures, cross-sectional predictability is tested. The primary findings are as follow; (1) the return patterns are bell shaped in all measures and (2) VaR and MDD do not capture additional risk factors after conditioning volatility.

This study investigates whether the cost of capital of Korean listed firms was substantially reduced after the IFRS adoption in long-term aspect and which firms listed in KOSPI or KOSDAQ market had been more enjoyed the benefit. Prior studies related to this subject don’t provided consistent results and have limitations of insufficiency of research periods and generalization problem. Therefore, this study analyzes the positive effect of the IFRS adoption in Korea using long-term based approach and differential measurements (CAPM and WACC) to facilitate generalization. Results of the study found that the cost of capital of Korean listed firms had been significantly reduced during 5 years after the IFRS adoption. In addition, the cost of capital of KOSPI listed firms was reduced more than KOSDAQ listed firms. The results provide meaningful implications to evaluate the effects of IFRS adoption on the cost of capital and to assess accomplishment of fundamental purpose of the IFRS adoption in Korea.

Allowing foreign strategic investors (FSIs) to hold minority stake in Chinese banks is very important for China’s banking. Based on data of 221 commercial banks from 2007 to 2015, we use difference in differences (DID) and propensity score matching (PSM) to investigate the effects of shareholding of FSIs on pricing of wealth management products (WMPs) for banks in China from single product view and every bank view. Besides, we further investigate the effects of bank ownership on above relationship. We find that FSIs’ acquisitions significantly enhance the expected rate of return of WMPs on both levels, however decrease the deviation of return of WMPs on single product level but have no evident effects on bank level. Finally, we find that the impact of acquisitions from foreign banks depend on Chinese banks’ ownership structure. Specifically, the effects of FSIs’ acquisitions on pricing of WMPs are positive for state-owned banks (SOBs), while are negative for city commercial banks.

The stock market efficiency is the idea that equity prices of listed companies reveal all the data regarding the company value (Fama, 1965). In this way, there isn’t possible to make additional returns. However, evidence against the Efficient Market Hypothesis is growing. Researchers studied Calendar Anomalies (CAs) that characterised financial markets. These CAs contradict the efficient hypothesis. This research studies some of the most important market anomalies in France, Germany, Italy and Spain stock exchange indexes in the first decade of new millennium (20012010). In this study, to verify the distribution of the returns and their auto correlation, we use statistical methods: the GARCH model and the OLS regression. The analysis doesn’t show strong proof of comprehensive Calendar Anomalies. Some of these effects are country-specific. Furthermore, these country-anomalies are instable in the first decade of new millennium, and this result demonstrates some doubt on the significance of CAs.
