Motivations and Use Context in Mobile Tourism Shopping: Applying Contingency and Task–Technology Fit Theories

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd.     

Korea's first industrial revolution, 1911–1940

We estimate output and population of colonial Korea to show that per capita output grew 2.3% with population expanding 1.3% per year from 1911 to 1940. Growth accounting indicated that productivity advance accounted for roughly one half of the per capita output growth. Primary production as a share of GDP fell from 69% to 42% during the period. Rapid productivity improvement caused nontradable sectors to become increasingly important, while capital accumulation drove industrialization. Demographic expansion, per capita output growth, and structural change occurred at considerably faster rates in northern than in southern provinces.     

Testing for structural stability in the whole sample

The paper examines a Lagrange Multiplier type test for the constancy of the parameter in general models with dependent data without imposing any artificial choice of the possible location of the break. In order to prove the asymptotic behaviour of the test, we extend a strong approximation result for partial sums of a sequence of random variables. We also present a Monte-Carlo experiment to examine the finite sample performance of the test and how it compares with tests which assume some knowledge of the possible location of the break.     

Understanding attributes affecting meal choice decisions in a bundling context

This study examined attributes that contribute to consumer meal choice decisions within a prix fixe menu. Drawing on typologies of consumer purchase behavior, factors potentially influencing consumers’ meal choice are identified and empirically tested. The results showed that consumers consider value for price as the most important consideration for their meal bundle choices. The results also indicated that familiar and healthy foods also contribute to the selection process. However, consumers tend to avoid the risk of choosing new menu items.     

Online Group-Buying of Tourism Products: Effects of Value and Trust on Site Attachment,Altruism, and Loyalty

Although online group-buying is increasing rapidly, little theoretically based research has been conducted on behaviors of online group-buyers of tourism products. Thus, the purpose of this study is to develop and test a theoretical model examining the relationships among value, trust, site attachment, altruism, and loyalty in the context of online group-buying of tourism products. The results indicate that the six hypothesized relationships among value, trust, site attachment, altruism, and loyalty are significant and thus validate the theoretical model. The findings of this study provide theoretical and practical implications for academics and managers of online group-buying sites.     

Subjectivity in fair-value estimates,audit quality,and informativeness of other comprehensive income

This study empirically examines whether difference in audit quality is reflected in the pricing of other comprehensive income (OCI). Specifically, we first investigate whether OCI measures of Big 4 clients are more value-relevant than those of non-Big 4 clients. Considering different degrees of subjective management judgment involved in the OCI reporting process, we then explore whether the differential valuation effect of OCI between Big 4 and non-Big 4 clients is more pronounced for more subjective OCI components (e.g., minimum pension liability and foreign currency-translation adjustment) than a less subjective component (e.g., marketable securities adjustment). We predict that the aggregate OCI of a Big 4 client is more value-relevant than that of a non-Big 4 client. We also hypothesize that the differential valuation effect between Big 4 and non-Big 4 clients can be attributed to the amount of subjective assumption and judgment required in estimating OCI. Consistent with our predictions, we find that aggregate OCI audited by a Big 4 auditor has incremental information content over earnings, compared to OCI audited by a non-Big 4 auditor. More interestingly, our results also show that the differential valuation effect between Big 4 and non-Big 4 clients is stronger for OCI components of a more subjective nature. Our results are robust even after controlling for self-selection bias, the potential effect of the financial crisis, and other related effects.     

Sampling Minority Business Owners and Their Families: The Understudied Entrepreneurial Experience*

We here review and critique prior research on minority entrepreneurship, paying particular attention to the contributions and limitations of deployed sampling techniques and research methodologies. As based on this review, we then introduce the 2003 and 2005 National Minority Business Owner Surveys—a comprehensive and primary data collection effort that used varied methodologies to secure in‐depth information about random national samples of African American, Korean American, and Mexican American populations as well as a comparison sample of nonminority business owners. We present the initial business ownership profiles developed with these recent data, in part, as a benchmark of the U.S. entrepreneurial experience, and compare the profiles with those presented in prior research. These profiles document similarities and differences across the four groups and provide an empirical foundation for understanding the origin of those similarities and differences. No longer can we ignore the in‐depth study of minority businesses and their owning families nor can we simply assume that all businesses are the same, regardless of minority status or ethnicity.     

Factors affecting international event visitors’ behavioral intentions: the moderating role of attachment avoidance

ABSTRACT

This study developed and tested a theoretical framework of event quality, motivation, value, and destination image in order to investigate visitors’ behavioral intentions to revisit an international event, along with the moderating role of attachment avoidance. Results revealed that the relationships among event quality, motivation, value, image, and behavioral intentions were highly significant. Attachment avoidance was additionally found to moderate the relationships between quality and value, motivation and value, value and destination image, and value and behavioral intentions. Findings further provide specific implications for both theoretical insight and marketing practice in the context of annual and international events.     

The impact of surprise offer-share adjustments on offer-day returns: evidence from seasoned equity offers

Using a sample of seasoned equity offerings (SEOs), we examine the eleventh-hour information carried by the final offer-share adjustment. We argue that if market participants interpret the final offer-share adjustment as a new information signal regarding the demand for the stocks issued, a greater final offer-share adjustment will affect the offer-day return positively (demand information hypothesis). Alternatively, if investors interpret the final offer-share adjustment as increasing the supply of stocks issued and/or as diluting the value of existing shares, a greater final offer-share adjustment will affect the offer-day returns negatively (price-pressure and dilution hypothesis). We provide empirical evidence that the offer-day returns are positively related to the final offer-share adjustment after controlling for confounding factors, supporting the demand information hypothesis. Our results also remain intact even after controlling for the endogeneity. Overall, our findings suggest that the final offer-share adjustment is another important determinant of offer-day returns, in addition to the final offer-price adjustment that Altinkiliç and Hansen [J Financ Econ 69(2):285–323 (2003)] report.
