Product survival analysis for the App Store

We empirically analyze both free and paid products on the top 100 Free and Grossing charts in the Korea App Store using Weibull parametric survival analysis on the product level. The findings are as follows: First, influences of ranking, customer ratings, and contents size on product survival are different for free and paid products. Customer ratings and contents size critically affect product survival when the price is zero. Second, the early entrant advantage exists in App Store, which results from a ranking system in the App Store and consumer learning. However, the effect of early entrant advantage differs between the Free and Grossing charts; the benefit of early entrant advantage is greater on the Free chart than that on the Grossing chart. Finally, we provide a competitive profit model that is related to free products.     

Product Market Competition and Lobbying Coordination in the U.S. Mobile Telecommunications Industry

This paper empirically investigates market behavior and firms?? lobbying in a unified structural setup. In a sequential game, where firms lobby for regulation before they compete in the product market, we derive a testable measure of lobbying coordination. Applying the setting to the early U.S. cellular services industry, we find that lobbying expenditures, as measured by campaign contributions, and market conduct were consistent with a one-shot Nash equilibrium and that price caps were binding on average. Furthermore, campaign contributions from cellular firms effectively lowered the burden of the price caps and reduced production costs.     

Assessment of the environmental sustainability of restaurants in the U.S.: The effects of restaurant characteristics on environmental sustainability performance

ABSTRACT

This paper investigated the current levels of environmental sustainability in restaurants across the U.S. to determine whether a restaurant’s proclivity for environmental sustainability depended on its characteristics such as chain affiliation or restaurant type.

A web-based survey was administered to 2,500 top-level restaurant managers, from which a total of 218 responses were judged as usable. The data were analyzed using independent

sample t-tests and ANOVA. This study presents an in-depth account of the environmental sustainability in restaurants across the U.S. based on an evaluation of top-level managers. This study also highlights the differences in restaurant environmental sustainability across different restaurant segments.     

Factors contributing to business actions in response to climate change in Korea

Climate change is a growing problem and has been highlighted as a global issue. Empirical evidence increasingly indicates its obvious potential risks to humans and society. As members of this society, business organizations face greatly diverse climate change-related risks that they must recognize and respond to. However, gaps exist between scientific evidence and the actions of business organizations. Few empirical studies have examined the business organizations’ actions taken in response to climate change in Korea. This paper addresses this critical gap in the climate change literature by examining business organizations’ behaviors and identifying the factors influencing their actions. We employ statistical models to compare corporate climate change actions, and we explain their variations using survey data. The results indicate that despite increasing concerns about climate change, businesses have implemented very limited precautionary mitigation and adaptation actions. In addition, the concerns of the businesses about future climate change impact, organizational capacity (leadership, staff capacity, existence of a relevant division or department), and business size are significant factors with respect to the implementation of climate change actions.     

Cultural attributes and risk perception: the moderating role of different types of research and development

Drawing on the grid–group culture theory, this study examines hypotheses to explain how the cultural attributes of an organization influence professionals’ perceptions of risk in the context of research and development (R&D) activities. Specifically, we explore whether two dimensions of cultural attributes – the grid dimension and the group dimension – affect organizational commitment and risk perception. We also investigate whether the impact of the cultural attributes on risk perception is mediated by organizational commitment and whether different types of R&D activities – applied research and developmental research – serve as a moderating variable on the relationships among cultural attributes, organizational commitment, and risk perception. The partial least squares method was used to analyze data collected from full-time senior researchers with over five years of experience at a large technology institute. Our findings indicate that cultural attributes influence the risk perception of R&D professionals through the mediating function of organizational commitment. Further, we found that different types of R&D activities have moderating effects on the relationship between organizational commitment and risk perception.     

Population Structure and Housing Prices: Evidence from Chinese Provincial Panel Data

This study analyzes the relationship between the proportion of the economically active population aged 15–64 to total population and housing prices. A panel of 31 provinces in China from 2002 to 2014 is used in our analysis. We find empirical evidence that the impact of the population structure on housing-price growth increases as the population growth rates rise. This observation suggests that, to understand provincial housing price movements in China, one should consider the ratio of working-age population to total population in a province. The main policy implication is that Chinese policymakers need to ensure a moderated population growth to effectively promote stability in housing prices and the economy.     

An empirical analysis of audit fee price competition after the Korean 1999 Omnibus Cartel Repeal Act

This study examines the audit service market in Korea after the 1999 Omnibus Cartel Repeal Act to determine if increased competition has led to audit fee discounting. Until 19 December 2001, when the Korean government enacted The Financial Supervisory Regulations, researchers could not address questions related to price competition in the Korean audit market due to data limitations. The new regulations allow researchers to examine audit effort for the first time because both audit hours and audit fees are now recommended disclosures. We use audit fee data of Korean companies for the 6-year period 1999–2004, and find evidence that total audit fees paid have been increasing but audit fees per hour have been decreasing. We also find that Big 5 auditing firms’ fees per hour are significantly lower than non-Big 5 auditing firms and are decreasing across time. These price pressures should be of concern to regulators and investors because prior research has demonstrated that price competition leads to discounting, which can result in unrealistically low audit fees and poor audit quality. Finally, as in previous research, we also find discounting of initial audit engagements in the Korean market.
