Evaluating and improving GARCH-based volatility forecasts with range-based estimators

This article investigates the feasibility of using range-based estimators to evaluate and improve Generalized Autoregressive Conditional Heteroscedasticity (GARCH)-based volatility forecasts due to their computational simplicity and readily availability. The empirical results show that daily range-based estimators are sound alternatives for true volatility proxies when using Superior Predictive Ability (SPA) test of Hansen (2005) to assess GARCH-based volatility forecasts. In addition, the inclusion of the range-based estimator of Garman and Klass (1980) can significantly improve the forecasting performance of GARCH-t model.     

Making customer relationship management work: evidence from the banking industry in Taiwan

Soon after becoming a WTO member, Taiwan found the internationalisation and liberalisation in the financial industry ushered its domestic banks into a new era. In response to this global trend, all its banks strove to rely on customer relationship management (CRM) to enhance customer value (CV). This study aims to probe further into the connection between CV and CRM. A series of examinations revealed that (1) both functional and social value impact customer behaviour directly and positively; (2) customer satisfaction positively and directly affects customer loyalty; (3) a positive and direct relationship exists between customer loyalty and customer behaviour; and (4) the positive and significant relationship between CV and customer behaviour can be developed through mediators such as customer satisfaction and customer loyalty. Consequently, banks should offer their customers different services, products, and marketing channels to meet their diversified needs to cultivate a win-win environment of CRM for both parties.     

Cross-Industry Emission Permits Trading

The present paper examines the effectiveness of emission permits trading across industries. We find that, while permits trading in a competitive environment minimizes costs of compliance, it also enhances product market imperfections. We also find that a standard-setting regulation yields superior welfare results if policy makers have able information. Standard setting allows policy makers the flexibility of taking into account the existing imperfections in each industry. Although not surprising, this result has important policy implications in situations in which policy makers consider establishing permits trading between publicly owned dominant polluters and other industrial polluters. Since policy makers have able information on publicly-owned firms, it might be welfare improving to directly control emissions of the dominant publicly-owned polluters. Given that many of the major polluters in the real world are large firms in heavily concentrated industries many of which are also regulated, our result warrants policy makers' attention.

Do futures‐based strategies enhance dynamic portfolio insurance?

In this paper we investigate the relative performance of two approaches to dynamic portfolio insurance: the synthetic put and the Constant Proportion Portfolio Insurance (CPPI). The investigation is conducted on the Australian market, over a sample period of 59 non‐overlapping quarters from December 1987 to December 2002. Its main contribution is to provide a comprehensive assessment of the two approaches under different market conditions, and the testing of ex ante information as an input into the trading program. The major finding is that the futures‐based implementation of both synthetic put and the CPPI approach is robust to both tranquil and turbulent market conditions in preserving the desired floor. The fact that this conclusion includes the case of employing implied volatility (obtained from the options market) is highly encouraging as it suggests high implementability of the strategy. Notably, the risk‐return tradeoff shows that portfolio insurance using this volatility measure yields a return that is 64 basis points over the risk free investment. © 2004 Wiley Periodicals, Inc.

Price stability through price-level targeting or inflation targeting? A tale of two experiments

Price stability can be attained through price-level or inflation targeting. This paper compares the two monetary policy strategies from both a historical and a theoretical perspective. The Swedish experiment with price-level targeting in the 1930 occurred within a framework that lacked the accountability characteristic of New Zealand's current policy framework for inflation-targeting. Using a simple forward-looking rational expectations framework, we show that price-level targeting offers a better output-inflation variability tradeoff than inflation targeting in the forward-looking New Keynesian framework.     

Corporate financing and anticipated credit rating changes

Firm circumstances change but rating agencies may not make timely revisions to their ratings, thereby increasing information asymmetry between firms and the market. We examine whether firms time the securities market before a credit rating agency publicly reveals its decision to change a firm’s credit rating. Using quarterly data, we show that firms adjust their financing structures before credit rating downgrades are publicly revealed. Specifically, firms on average increase their debt financing by 1.29 % before the disclosure of a rating downgrade, and this increase is due to the issuance of debt rather than the repurchase of equity. In contrast, firms do not take significant financing actions before credit rating upgrades.     

Productivity and impact in advertising research since the millennium: a profiling and investigation of drivers of impact

What does it take to become a top advertising scholar in productivity? What drives impact in advertising research? This article sets out to answer these two questions by assessing the productivity and impact among scholars and their work in advertising since the millennium. As a two-part study, we begin by benchmarking and profiling the top 1% scholars in the field based on their research publications in the three top advertising journals (Journal of Advertising, Journal of Advertising Research, and International Journal of Advertising). Next, we employ a three-perspective conceptual model to identify the salient drivers of impact in advertising research. By content analyzing 1443 articles in the three journals published between 2000 and 2014, we show that certain universalistic and particularistic factors (to a lesser extent) significantly predict paper citations. Our findings reveal how advertising academia is advancing and showing signs of internationalization in the new millennium, which provides implications for the field's advancement and scholarship.
