Consistency of option prices under bid–ask spreads

Given a finite set of European call option prices on a single underlying, we want to know when there is a market model that is consistent with these prices. In contrast to previous studies, we allow models where the underlying trades at a bid–ask spread. The main question then is how large (in terms of a deterministic bound) this spread must be to explain the given prices. We fully solve this problem in the case of a single maturity, and give several partial results for multiple maturities. For the latter, our main mathematical tool is a recent result on approximation by peacocks.     

Compliance Costs of Corporate Income Taxation in Singapore

This study is the second in a series of studies investigating tax compliance costs incurred by public-listed companies. We found evidence of a size effect which is a predominant finding of similar studies. The size effect was more pronounced when absolute measures of costs were used than when a relative measure, cost/sales turnover, was used. Additional evidence was found of limited success relating to the IRAS's moves to simplify the tax system. Specifically, only large companies with sales turnover exceeding $500m benefited and considerably reduced their overall compliance costs. Most of the decrease was a result of the computational component of compliance costs. This resulted in the gap in absolute costs narrowing between Group 3 and any of the other categories of companies. There was also greater reliance on external professionals, the smaller the company. Views elicited indicate that more could be done to increase accessibility to IRAS publications for Group 1 and Group 2 companies.     

Effects of Stability and Controllability Attribution on Service Recovery Evaluation in the Context of the Airline Industry

This study examines the relationships between service recovery, stability and controllability attribution, recovery satisfaction, and customer loyalty. We collected data on service recovery, failure attribution, recovery satisfaction, and customer loyalty through a survey of airline passengers in Malaysia. The results indicate significant positive relationships between service recovery dimensions and recovery satisfaction, and between recovery satisfaction and customer loyalty. Both stability and controllability were negatively related to recovery satisfaction. The results provide support for the moderating effects of service failure attribution (stability and controllability) in the recovery process dimension. By recognizing the important role of stability and controllability attribution and its negative effects, service management should become highly involved in facilitating appropriate service recovery to satisfy customers after a failure. The results have important implications and suggest some interesting avenues for future research.     

Persistence and non-linearity in US unemployment: A regime-switching approach

This article examines persistence and nonlinearity in the US unemployment rate in the post-war period by using a regime-switching unit root test. The empirical results indicate that a regime-switching unit root test outperforms conventional unit root tests and describes unemployment behavior better over the business cycle in the sample. While shocks to US unemployment dissipate in expansions, shocks to the unemployment rate seem to be persistent in recessions, supporting the hysteresis hypothesis. This is consistent with the usual explanation of hysteresis that workers may lose valuable job skills in protracted recessions.     

Market orientation practices among small and medium hotels (SMHS) in tourist destination island of Langkawi

The purpose of the study is to investigate the underlying components of market orientation practices and their effect on the Small and Medium Hotels (SMHs) performances on tourist destination island of Langkawi. Fifty SMHs were randomly selected from a sampling frame of a list of SMHs registered with Malaysian Tourism Board. For data collection purposes, structured questionnaires were personally delivered and collected. Rotated component matrix factor analysis of the data extracted four underlying factors that explain seventy nine point four six percent of the total variances and alpha reliability coefficient of ninety eight percent. Those components were named as customer orientation, interfunctional orientation, service orientation, and competitor orientation. One sample Kolmogorov‐Smirnov Test indicates that SMHs in Langkawi practices market orientation in their operations and businesses. However, the finding of the study showed that their performances in 1998 was lower than 1997. We believe that this outcome is due to the effect of national and regional economic downturn in 1998.     

Designing a framework for acquiring technological knowledge among technology transfer recipients A perspective from a radar

Technology transfer is becoming increasingly important for business and economic growth in developing nations. The modern global economy uses knowledge resources to increase productivity and foster improvements in standard of living. Individual businesses acquire knowledge of advanced technologies to establish and maintain competitive positioning in the global marketplace. Without proper knowledge acquisition, transfer of technology cannot take place. The process of acquiring knowledge requires the organization to choose or adapt elements of the technology to local cultural conditions to integrate it with indigenous technologies. The cultural context of the recipient can also affect the process of acquiring knowledge. The culture and social environment of the individual creates a schema for organizing knowledge and understanding reality. This paper has two objectives： Firstly, to investigate how organisational culture affects readiness for technology transfer, and secondly, to identify elements of organisational culture affecting readiness for technology transfer. Qualitative mode of data collection was used in this study as well as interview and focus group discussion. The results from the preliminary investigations were used to create the components of the framework. Hypotheses were formulated between the constructs of the framework and a rigorous attempt was made using Structural Equation Modelling （SEM） to validate the construct as they created through qualitative findings.
