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. 相似文献

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. 相似文献

An appropriate market definition is critical in most antitrust cases. In practice, antitrust authorities define economic markets
in a deterministic manner with little concern about the risk involved in defining markets incorrectly. In contrast, this article
proposes a probabilistic market definition method by which antitrust authorities can establish a statistical confidence level
for their intended market-definition judgments. As an application, we examine the likelihood that the fixed-line and mobile
telephony services in Korea can compete in the same economic market. Combining critical loss analysis with a hierarchical
Bayes model for stated preference data, we find some evidence for the separation of the fixed-line and mobile telephony markets
in present-day Korea. After discussing certain possible regulation biases for market definition, we predict that the two markets
will converge in the near future as the mobile price premium continues to decrease. 相似文献

In this study I examine the effect of a firm's reputation for product quality on its effort in learning to reduce its product defect rate. Theoretical ideas on the motivation of learning associated with social aspiration levels and the self-serving bias combined with social categorization suggest that poor quality reputation firms are more likely than their counterparts with a good reputation to attend to potential product defects and consequently reduce their defect rate. However, a stream of research on the motivation of learning stemming from historical aspiration levels and slack search leads to a different argument: a reputation for good quality is more likely to provide firms with a motivation to avoid product defects. I build upon these two competing arguments and hypothesize that stronger motives for learning exist in situations where firms have either a weak or strong reputation for product quality. My study of product recalls in the US automotive industry highlights an inverted U-shaped relationship, indicating the liability of an intermediate reputation in reducing product defects. 相似文献

New Keynesian macroeconomic models predict that monetary shocks have asymmetric effects on inflation, i.e., inflation responds more to positive monetary shocks than to negative shocks (Asymmetry Hypothesis A), and that the asymmetry is positively associated with movements in average inflation (Asymmetry Hypothesis B). Korean data are shown to provide little support for Asymmetry Hypothesis A and strong support for Asymmetry Hypothesis B. [O53, E12] 相似文献

Disagreement exists about the potential effects of changes in competition on relationship lending. Boot and Thakor (2000) predict that an increase in capital market competition should lead to a reduction in relationship lending; however, Dinç (2000) predicts that greater capital market competition should increase relationship lending. Thus far, data limitations have precluded empirical tests of these competing hypotheses. In this study, we use a unique data set drawn from the deregulation of the Japanese financial system. Our findings show that increased capital market competition is associated with reduced relationship lending. However, the effect differs according to the maturity of the loans; increased capital market competition is associated with reduced long-term, but greater short-term, relationship lending. 相似文献

We propose a measure for extreme downside risk (EDR) to investigate whether bearing such a risk is rewarded by higher expected stock returns. By constructing an EDR proxy with the left tail index in the classical generalized extreme value distribution, we document a significantly positive EDR premium in cross-section of stock returns even after controlling for market, size, value, momentum, and liquidity effects. The EDR premium is more prominent among glamor stocks and when high market returns are expected. High-EDR stocks are generally characterized by high idiosyncratic risk, large downside beta, lower coskewness and cokurtosis, and high bankruptcy risk. The EDR premium persists after these characteristics are controlled for. Although Value at Risk (VaR) plays a significant role in explaining the EDR premium, it cannot completely subsume the EDR effect. 相似文献

Most recent studies have employed the cointegration technique to investigate the long-run stability of the demand for money. This study considers the case of Korea. It is shown that in the long-run while Ml monetary aggregate is cointegrated with income, interest rate, and the exchange rate, M2 is not. However, results from error correction models reveal that both Ml and M2 have short-run relationship with their determinants. [E41] 相似文献

This paper discusses the issues in estimating the effects of marketing variables with linear models. When the variables are
not directly observable, it is well known that direct regression yields biased estimates. Several researchers have recently
suggested reverse regression as an alternative procedure. However, it is shown that the reverse regression approach also fails
to provide unbiased estimates in general, except for some special cases. It is proposed that covariance structure analysis
with an appropriate measurement model can ensure the unbiasedness of estimated effects. These issues are examined in the context
of assessing market pioneer advantages.
