农民养老风险、策略与期望的代际差异

文章基于全国10个省份1032位农民的调查数据,利用交互分析、卡方检验和单因素方差分析方法,实证分析农民养老风险、策略与期望的代际差异。研究表明,农民养老风险并不非常突出,但代际差异明显;农民养老策略,形成了一种以独立养老为主、以家庭养老为基础、以社会养老为补充的"福利三角"框架,从20世纪50年代到80年代,农民独立养老意识逐渐增强,社会养老保险正在被农民所接受,家庭养老在农民养老策略中处于基础和稳定地位;在面临养老困境时,农民依然把最大的期望寄托在子女身上,但其权利意识和法律意识正在觉醒。

Interaction effects of formal and social controls on business-to-business performance

Marketing and Strategy studies have treated relational governance as a critical factor of business-to-business (B2B) performance. Extant studies offer contrasting views on whether formal or social control is a better control mechanism, with little known about their interaction effect. In this study, the authors aim to investigate the interaction effect of these two control mechanisms by dividing a B2B contract (formal control) into two provisions (transactional and relational) and to examine the specific interaction effect of social control on each provision. The authors also seek to investigate the moderating effects of environmental dynamism, prior ties, and buyer lock-in. The measure of B2B performance reflects relational quality and financial outcome. The results show significantly different interactions between each provision of the contract and social control depending on the level of environmental dynamism and buyer lock-in, and suggest that the environmental condition of the transactions is reflective of managers' optimal control mechanisms.     

Financial Factors in the Business Cycle of a Small Open Economy: The Case of Korea

Financial factors influencing the business cycle have received considerable attention in recent years in the aftermath of the global financial crisis in 2008. This paper examines the role of financial factors in the business cycle by considering Korea, a small open economy, that experienced a severe financial crisis in 1997 as well as the recent global financial crisis. We estimate small open economy Bayesian DSGE (dynamic stochastic general equilibrium) models with financial factors and analyze the role of these financial factors in the business cycle in the context of Korea. The results indicate that the model based on an endogenous financial accelerator and a modified monetary policy rule provides a better explanation to the data than that without the financial factors and justify the recent attention to financial factors influencing the business cycle.     

Diagnosing service quality using customer reviews: an index approach based on sentiment and gap analyses

Recognizing the importance and potential benefits of customer reviews as a source of the voice of customers, this study proposes an analytic framework and procedures for analyzing customer reviews—termed a customer review-based gap analysis—that are tailored to diagnosing service quality. To this end, we conduct sentiment analysis on customer reviews to capture customers’ perceptions and expectations at the service-feature level, which are not expressed explicitly in their reviews. A case study of a mobile navigation service shows that the customer review-based gap analysis can provide the practical information required to diagnose service quality from customer review data. The suggested indexes for capturing customers’ perceptions and expectations reveal quality strengths and drawbacks at the service-feature level. In addition, incorporating these indexes into those for quality performance and objectives based on a service-feature hierarchy provides a diagnostic tool capable of examining service quality in both overall as well as detailed aspects.

How does the call market method affect price efficiency? Evidence from the Singapore Stock Market

On August 21, 2000, the Singapore Exchange (SGX) adopted the call market method to open and close the market while the remainder of the day’s trading continued to rely on the continuous auction method. The call method significantly improved the price discovery process and market quality. A positive spillover effect is observed from the opening and closing calls. Day-end price manipulation also declined after the introduction of the call market method. However, the beneficial impact from the call market method is asymmetric, benefiting liquid stocks more than illiquid stocks.

Targeting Rules for an Open Economy

This study extends the formal analysis of inflation targeting monetary policy using the standard New Keynesian framework to a small open economy by adding inflation and output persistence as well as a direct exchange rate channel to domestic inflation. We find that output variability is lower under CPI inflation targeting than under domestic inflation targeting. However, CPI inflation results in higher variability of the real exchange rate than domestic inflation targeting. Output and the nominal interest rate are less volatile under flexible inflation targeting than under almost-strict inflation targeting. We also find that almost-strict domestic inflation targeting cannot completely insulate domestic inflation from foreign shocks due to a direct exchange rate channel. The model is calibrated to Canadian data.
