In this rapidly evolving market, software development is an ongoing process thatmust be tailored to meet the dynamic needs of enterprises. However, internal research and development can beprohibitively expensive, driving many enterprises to outsource software development and upgrades to externalservice providers. This paper presents a software upgrade outsourcing model for enterprises and service providersthat accounts for the impact of market fluctuations on software adaptability. To mitigate the risk of adverseselection due to asymmetric information about the service provider’s cost and asymmetric information aboutthe enterprise’s revenues, we propose pay-per-time and revenue-sharing contracts in two distinct informationasymmetry scenarios. These two contracts specify the time and transfer payments for software upgrades. Througha comparative analysis of the optimal solutions under the two contracts and centralized decision-making withfull-information, we examine the characteristics of the solutions under two information asymmetry scenarios andanalyze the incentive effects of the two contracts on the various stakeholders. Overall, our study offers valuableinsights for firms seeking to optimize their outsourcing strategies and maximize their returns on investment insoftware upgrades.展开更多

The amplitude A is introduced to describe the degree of information asymmetry. It is found that there exists an optimal value of amplitude Aopt at which the fraction of cooperation reaches its maximal value. The reason lies in that cooperators on the two-dimensional grid form large clusters at Aopt. In addition, the theoretical analysis in terms of the mean- field theory is used to understand this kind of phenomenon. It is confirmed that the information asymmetry plays an important role in the dynamics of the dilemma games of spatial prisoners.展开更多

The present study proposes a new perspective to address the issue in the case of China "s forward exchange rate market. Following the framework of Clarida and Taylor (1997), the term structures of exchange rates in the domestic forward and the non-deliverable forward markets are constructed and then applied to predict future spot exchange rates based on a vector equilibrium correction model By comparing the forecast accuracy on the basis of the root mean square error and the mean absolute error, it is shown that dynamic out-of- sample forecasts of the domestic forward market are superior to those of the non-deliverable forward market, suggesting that domestic investors are better informed than foreign investors. The result has several important policy implications, especially for exchange rate determination.展开更多

Asymmetric information between listed companies and investors is another important determinant: The higher the degree of information asymmetry, the greater the private placement discounts.展开更多

Using hand-collected managerial background data from a sample of firms listed on the Shanghai and Shenzhen Stock Exchanges from 2010 to 2014, this paper investigates the impact of returnee managers on corporate social responsibility (CSR) performance. We find that returnee managers can promote CSR performance. Further analyses show that the impact of returnee managers on CSR is more pronounced when managers have a foreign study background compared to managers with foreign work experience. The impact only holds when managers obtained their experience in developed economies. When enterprises face greater information asymmetry, returnee managers are more willing to use CSR as a tool to convey a positive image to stakeholders. CSR can help managers reduce information asymmetry and improve firm value. The results are robust through a series of robustness checks including a propensity score matching (PSM) procedure and a Heckman two-state sample selection model. This paper contributes to growing studies on the economic consequences of returnee managers and advances our understanding of the determinants of CSR at the individual level. The results also have implications for government and enterprises attracting talents with overseas experience.展开更多

We argue again...As a major global exchange, the Stock Exchange of Hong Kong (SEHK) only requires semi-annual reporting whereas other major exchanges including the ones in Chinese mainland require quarterly reporting. We argue against the traditional view that higher reporting frequency is necessarily more beneficial. The decision on reporting frequency depends on how the information is being processed by the recipient traders and the results are not obvious. Using a sample of Chinese companies dual- listed in both China A share market and SEHK (AH shares) as the experimental group and mainland's companies listed on SEHK (H shares) only as the control group, we apply the difference-in-difference (DID) method to investigate the impacts of reporting frequency on stock information quality. The results suggest that after China A share market require quarterly financial reporting for all listed companies in 2002, the information asymmetry of the H tranche of AH stocks increases. Different from prior studies, the results suggest a negative association between stock information quality and financial reporting frequency. We argue that the increased information asymmetry in the H tranche is caused by the noise spilled over from the A tranche. We conduct multivariable GARCH tests and find evidence supporting this conjecture.展开更多

Heterogeneous service is a major reason resulting in imbalances between supply and demand. Since customers differ in their degree of impatience, firrns can use differential pricing mechanisms to optimize their objectives and match supply with demand in each period, by inducing customers to choose different periods. We study two types of firrns, an internal firm, the objective of which is to maximize the system's (including the f'nan and all the customers) total net value, and a commercial firm, which aims to optimize its own profit. Though impatience factors are customers' private information, for each type of firm, we derive the optimal incentive compatible pricing policy, under which all the coming customers will follow the firm's assignment, that is, patient customers will buy the service in high-value periods, but their waiting time will be longer, while impatient customers will enter into the low-value periods, but they will be compensated by shorter waiting times. Furthermore, in the internal firm, we also prove that this mechanism enables the decentralization of decisions, while maintaining centralized system-wide optimality. Numerical analysis shows that when there is sufficient capacity, the internal firm does not always need to set lower prices than the commercial firm in every period.展开更多

文摘We analyze whether product market advertising has a spillover effect on stock price synchronicity by transmitting firm-specific information to the capital market and attracting more investor attention.Using a sample of Chinese listed firms from 2009 to 2017,we find that firms with greater advertising expenditures have lower stock price synchronicity.The results are robust after we address endogeneity concerns.In accord with our hypothesis that product market advertising increases the amount of firm-level information capitalized into stock prices through the information channel,we find that the impact of advertising on synchronicity is more pronounced for firms with a higher degree of information asymmetry and firms in the consumer-product industry.Further tests show that product market advertising enhances the ability of current period returns to reflect future earnings,and thus rules out that the negative relationship between advertising and synchronicity is driven by noise trading.Our results imply that product market advertising plays an informative role and improves information efficiency in a capital market.
文摘With growing economic globalization, returnee managers who have obtained education or work experience overseas play a much more crucial role in corporations, especially in emerging economies. Using hand-collected managerial background data from a sample of firms listed on the Shanghai and Shenzhen Stock Exchanges from 2010 to 2014, this paper investigates the impact of returnee managers on corporate social responsibility (CSR) performance. We find that returnee managers can promote CSR performance. Further analyses show that the impact of returnee managers on CSR is more pronounced when managers have a foreign study background compared to managers with foreign work experience. The impact only holds when managers obtained their experience in developed economies. When enterprises face greater information asymmetry, returnee managers are more willing to use CSR as a tool to convey a positive image to stakeholders. CSR can help managers reduce information asymmetry and improve firm value. The results are robust through a series of robustness checks including a propensity score matching (PSM) procedure and a Heckman two-state sample selection model. This paper contributes to growing studies on the economic consequences of returnee managers and advances our understanding of the determinants of CSR at the individual level. The results also have implications for government and enterprises attracting talents with overseas experience.
文摘As a major global exchange, the Stock Exchange of Hong Kong (SEHK) only requires semi-annual reporting whereas other major exchanges including the ones in Chinese mainland require quarterly reporting. We argue against the traditional view that higher reporting frequency is necessarily more beneficial. The decision on reporting frequency depends on how the information is being processed by the recipient traders and the results are not obvious. Using a sample of Chinese companies dual- listed in both China A share market and SEHK (AH shares) as the experimental group and mainland's companies listed on SEHK (H shares) only as the control group, we apply the difference-in-difference (DID) method to investigate the impacts of reporting frequency on stock information quality. The results suggest that after China A share market require quarterly financial reporting for all listed companies in 2002, the information asymmetry of the H tranche of AH stocks increases. Different from prior studies, the results suggest a negative association between stock information quality and financial reporting frequency. We argue that the increased information asymmetry in the H tranche is caused by the noise spilled over from the A tranche. We conduct multivariable GARCH tests and find evidence supporting this conjecture.

文摘This paper studies a service firm whose business time can be divided into several periods, each providing different value to customers. Heterogeneous service is a major reason resulting in imbalances between supply and demand. Since customers differ in their degree of impatience, firrns can use differential pricing mechanisms to optimize their objectives and match supply with demand in each period, by inducing customers to choose different periods. We study two types of firrns, an internal firm, the objective of which is to maximize the system's (including the f'nan and all the customers) total net value, and a commercial firm, which aims to optimize its own profit. Though impatience factors are customers' private information, for each type of firm, we derive the optimal incentive compatible pricing policy, under which all the coming customers will follow the firm's assignment, that is, patient customers will buy the service in high-value periods, but their waiting time will be longer, while impatient customers will enter into the low-value periods, but they will be compensated by shorter waiting times. Furthermore, in the internal firm, we also prove that this mechanism enables the decentralization of decisions, while maintaining centralized system-wide optimality. Numerical analysis shows that when there is sufficient capacity, the internal firm does not always need to set lower prices than the commercial firm in every period.
