Innovation management in service firms: a research agenda

This article suggests an agenda for further research on innovation management in service firms. It investigates differences and similarities between issues identified by previous academic research and issues brought up by practitioners within the area of innovation management in service firms. The results show that there are some major differences; for instance, researchers stress a need for formalized processes for development work, while practitioners focus on facilitating innovation in everyday operations. The main conclusion is that in order to bridge the gap between research and practice we would encourage further research on innovation in service firms to (1) conduct micro studies of innovation work, (2) view innovation in the context of everyday operations and (3) focus on co-workers’ innovative potential.     

Are Derivative Warrants Overpriced?

This study investigates the pricing efficiency of Hang Seng Index (HSI) derivative warrants in Hong Kong. Different from similar research, the study examines the pricing efficiency of index warrants by comparing their implied volatilities (IV) with realized volatility (RV). Although prior studies find that warrants are more expensive than the corresponding options, they are not necessarily overpriced in the conventional sense—that is, relative to the RV. This approach allows the study to test the pricing efficiency of warrants via a test of their information content. Moreover, unlike studies that focus on data at market close, the study uses a large sample of highly synchronous intraday, firm, bid–ask quote data to avoid possible distortions arising from intraday variations in liquidity and pricing in the instruments. The data also helps eliminate the potential nonsynchronous price problem that may affect the test results. Consistent with the results from previous studies, we find that warrants are often more expensive than options. This result is attributed to the inability of non‐issuers to sell short, and the high participation rate of unsophisticated investors in the warrants market. However, regression analysis shows that IVs from ATM and OTM warrants provide unbiased volatility forecasts, and that IVs from ATM options do not subsume the information content of ATM warrants. ATM warrant prices are in line with the RV and are efficiently priced. Simulation results show that writing warrants is more profitable than writing options, and that the overpricing is directly related to the volatility premium.     

Decentralizing Tragic Choices: Pooling Health Risks with Health Unions

ABSTRACT Pooling health risks through insurance has led to cost explosion because centralized third-party payers cannot deny even cost ineffective treatment for life-and-death cases without arousing a sense of tragedy and inviting legal challenges. If the same total health budget is distributed equally on a per capita basis, funding decisions for treatment can then be voted on in a decentralized manner. Because unfunded treatment would be a result of majority choice and not bureaucratic decision, both a sense of tragedy and legal challenges can be avoided. Health unions that serve as fund-raising agencies and consumer advocates can coordinate such voting.     

Macroeconomic Control in the Transforming Chinese Economy: An Analysis of the Long‐Run Effect

This paper analyzes the issue of macroeconomic control in the Chinese economy where there is a dual structure (consisting of a state sector and a non‐state sector) and the financial sector is still under tight control by the government. Given the dual structure and financial repression, when inflation is a severe problem, the authors investigate whether it is possible for the government to bring inflation under control without hampering long‐term economic growth performance. The investigation is conducted within the context of an endogenous growth model that incorporates the two major institutional features of the transforming Chinese economy. The paper evaluates the long‐run effects of changes in government monetary and fiscal policies on the major macroeconomic aggregates. The analysis suggests that increasing in the interest rate on government bonds will reduce inflation without affecting the growth rate of output; while increasing the nominal interest rate on bank deposits will exert a stagflationary effect on the economy: raising the inflation rate but reducing the growth rate of output.     

The impact of outward FDI on the home country's labour demand and skill composition

The present paper adds to the literature investigating the effects of outward FDI on the home country employment and skill composition. Considering the “industrial region” as the unit of the analysis, we capture both direct and indirect effects of foreign production on the parent company and its environment. The empirical evidence refers to the internationalisation of production by Italian firms throughout the period 1996–2002, and it shows that foreign activities have a negative impact upon the demand for low skilled workers in the parent company's “industrial region”, but also on the demand for high skilled workers when FDI are addressed to high income countries.     

An analysis of members' perspectives of service quality in Hong Kong tourist association membership system

The objectives of the study were (1) to evaluate members' satisfaction and expectation towards the quality of services provided by the HKTA membership system; (2) to identify the performance “gap” between members' satisfaction and expectation in the HKTA membership system; and, (3) to explore the impact of members' satisfaction level in participating in the HKTA membership system. A comprehensive survey was conducted and a Simple Random Sampling plan was used to survey 600 members. It was found that 28 out of 32 attributes had negative performance “gaps.” The likelihood of participating in HKTA activities was dependant on the members' satisfaction in “Increase social awareness,” “Opportunities to liaise with business associates” and “Upgrading staff through training courses.” The implications of the findings were discussed and recommendations were proposed.     

Does competition influence bank failures?

There has been a notable debate in the banking literature on the impact of bank competition on financial stability. The aim of this article is to provide the first investigation of the role of bank competition on the occurrence of bank failures. We analyse this issue on a large sample of Russian banks for the period 2001–2007, as the Russian banking industry is a unique example of an emerging market which has undergone a large number of bank failures during the last decade. Our findings support the view that tighter bank competition enhances the occurrence of bank failures. Thus, measures that increase bank competition could undermine financial stability.

Modelling and Estimation for Bivariate Financial Returns

Maximum likelihood estimates are obtained for long data sets of bivariate financial returns using mixing representation of the bivariate (skew) Variance Gamma (VG) and two (skew) t distributions. By analysing simulated and real data, issues such as asymptotic lower tail dependence and competitiveness of the three models are illustrated. A brief review of the properties of the models is included. The present paper is a companion to papers in this journal by Demarta & McNeil and Finlay & Seneta.     

Overreaction in the Hong Kong stock market

Overreaction reported in the equity markets of the United States, Spain, and Brazil is also observed in the Hong Kong stock market. The “loser” portfolios of the 33 stocks in the Hang Seng Index (HSI), on average, outperform the “winner” portfolios by 9.9% 1 year after the formation periods. Besides its emphasis on the importance of the Hong Kong market in international investment, this paper is unique in some special features related to the overreaction study. Hong Kong has markets for index futures and stock futures. Only three stocks are used in the portfolios. All the stocks in the HSI have large market capitalization and liquidity and can be shorted with no up-tick rule. Unlike other studies in international stock markets, the “arbitrage” portfolio of buying the loser portfolio and shorting the winner portfolio can actually be formed with minimum cost and easy execution, which makes the overreaction phenomena in this study very powerful.
