Re-evaluation of global innovation index based on a structural equation model

The Global Innovation Index (GII) was proposed to observe the innovation capability and efficiency levels of individual countries using input and output factors. However, it does not consider potential structural relationships among factors affecting the innovation performance of a country. In this study, we proposed a structural equation model (SEM) based on the hypothesised national innovation structure among seven factors representing inputs (institution, human capital and research, infrastructure, market sophistication, and business sophistication) and outputs (knowledge and technology outputs, and creative outputs). Using GII data from 2013, we discovered that business sophistication and infrastructure have the strongest direct and indirect effects on creative output, respectively. In addition, a new ranking is obtained based on the fitted SEM. We provide feedback information to improve innovation capabilities.     

Limitations and Strengths of Pan-Asian Advertising Media: A Review for International Advertisers

Economic growth in Asia has led to a proliferation in the supply of pan-regional media. Most of these are elitist media targeting affluent businessmen and travellers. The increasing importance of the Chinese-speaking market spurs the growth of Chinese language pan-Asian media. The emergence of satellite television networks popularizes pan-regional media to a broader audience, although its penetration is still small in comparison to local media. When selecting pan-regional media for advertising in the region, advertisers are advised to use data from pan-Asian audience surveys, publication audit figures and competitive advertising expenditure reports in examining the cost-efficiency of each media vehicle. In choosing between pan-regional and local media, advertisers should consider the homogeneity and socio-economic status of their target audience, the importance of international recognition and consistency in image for the brand, geographic strengths, and other added values of the media.     

Becoming a founder: How founder role identity affects entrepreneurial transitions and persistence in founding

We develop a new theory that views organizational founding as involving a role transition. Through the construct of founder role identity, we delineate how identity centrality and complexity affect individuals' ability to exit a work role in order to undertake founding activities. We argue that individuals are challenged to adjust to the founder role requirements and incorporate the new role into an overall self-concept. We then delineate how configurations of founder role identities influence persistence, and the longer-term outcomes of dormancy and successful founding.     

Information and adjustment in a local housing market

Existing studies on bubbles have been mainly concerned with investigating the stationarity properties of stock prices and market fundamentals. We develop a new method of testing for bubbles that relates the bubble component of stock prices to the probability of bursting in the context of the Weibull distribution. There were several eruptions and subsequent collapses of seeming bubbles over the past three decades: 1987 (Black Monday), 2000 (information technology (IT) boom) and 2007 (housing market boom). Using US monthly data for the S&P 500 and NASDAQ series, we have found that the S&P 500 series contained an explosive bubble only during the boom of the housing market that occurred before the 2007 global economic crisis, and the NASDAQ market contained an explosive bubble during the surge of stock prices peaking in 1987 and 2007, although our stationarity tests fail to detect the bubbles. No bubble was found in both the S&P and NASDAQ series during the 2000 IT boom. Our evidence corroborates the criticism that the traditional unit root and cointegration tests may not be able to detect some important class of bubbles.

THE INFORMATIONAL ROLE OF BANK LOAN RATINGS

We analyze the relatively new phenomenon of credit ratings on syndicated loans, asking first whether they convey information to the capital markets. Our event studies show that initial loan ratings and upgrades are not informative, but downgrades are. The market anticipates downgrades to some extent, however. We also examine whether public information reflecting borrower default characteristics explains cross‐sectional variation in loan ratings and find that ratings are only partially predictable. Our evidence suggests that loan and bond ratings are not determined by the same model. Finally, we estimate a credit spread model incorporating bank loan ratings and other factors reflecting default risk, information asymmetry, and agency problems. We find that ratings are related to loan rates, given the effect of other influences on yields, suggesting that ratings provide information not reflected in financial information. Ratings may capture idiosyncratic information about recovery rates, as each of the agencies claims, or information about default prospects not available to the market.     

The NBA, Exit Discrimination, and Career Earnings

The purpose of this article is threefold. First, it complements the many wage discrimination studies by examining exit discrimination in the NBA using a decade's worth of data (the 1980s). White players have a 36 percent lower risk of being cut than black players, ceteris paribus , translating into an expected career length of 7.5 seasons for an apparently similar player who is white and 5.5 seasons for the same player who is black. Second, the career earnings effect of exit discrimination in the 1980s is larger ($808,000) than the career earnings effect of wage discrimination ($329,000). Third, our data are consistent with the hypothesis that customer racial discrimination is the reason for the observed exit discrimination.     

Online shoppers in Australia: dealing with problems

Although the Internet is a convenient platform to conduct commercial transactions, consumers are disadvantaged in the online marketplace due to insufficient information about goods and services as well as business and transaction process, lack of access to redress and several other problems. The number of complaints regarding online transactions increased in Australia from 2001 to 2005, and the number of Internet‐fraud related complaints reported to Consumer Sentinel (USA ) also increased from 2003 to 2006. This, in turn, has undermined consumer trust and impeded the growth of e‐retailing as well as added to the fear among e‐consumers of falling prey to online fraud. In spite of this, the nature and effectiveness of e‐consumer protection has not been adequately studied, notwithstanding extensive research into other aspects of e‐retailing. This article examines (i) the level of awareness of the respondents in the survey in Australia of the current policy framework for addressing consumer protection about online shopping in terms of redress; and (ii) the behaviour of the two groups of respondents in this survey who have and have not encountered problems with online purchases. The findings suggest that most respondents are not aware of the following issues, namely (i) which organizations are involved in e‐consumer protection; (ii) government regulations and guidelines; (iii) industry codes of conduct; (iv) self‐regulatory approaches adopted by business; and (v) the activities of consumer associations to protect consumers in the online marketplace. The findings also show that most respondents would seek redress if they were unhappy with their online purchases and if they knew how to proceed, and that most of them would settle disputes directly with e‐retailers. Also, online shoppers who had encountered problems were more likely to continue purchasing via the Internet than online shoppers who had not encountered any problems. This suggests that respondents find that the benefits offered by e‐retailing outweigh the risks associated with it.     

Nonlinear regression approach to evaluate nutrient delivery coefficient.

Implementation of the Korean Total Maximum Daily Load Act calls for new tools to quantify nutrient losses from diffuse sources at a river basin district scale. In this study, it was elucidated that the nonlinear regression model (NRM) reduces the uncertainty of the boundary conditions of the water quality model. The NRM was proposed to analyse the delivery coefficients of surface waters and retention coefficients of pollutants. Delivery coefficient of pollution load was considered as a function of two variables: the watershed form ratio, S(f), which is a measurable geomorphologic variable and the retention coefficient, phi, which is an empirical constant representing the basin-wide retarding capacity of pollutant wash-off. This model was applied on the Geum River, one of the major basins in South Korea. The QUAL2E was used to simulate stream water quality using NRM. In this paper, we elucidate the possibility to use a nonlinear regression model for delivery and retention of nutrients in a drainage basin characterized as both data-rich and data-poor, and the magnitude of the nutrient loads and sources has been uncertain for a long time.
