House Price Dynamics with Household Debt: The Korean Case*

This paper revisits the long‐run determinants of house prices, and analyzes the house price dynamics using Korean data taking into account the close relationship between house prices and household debt. The results of cointegrating regression indicate that the major portion of the rise in house prices in Korea over the last 15 years can be explained by changes in macro variables such as household income, the demographic structure, the user cost of home ownership and the housing stock supply. The results also confirm that house prices are, indeed, closely linked to the steep increase in household debt seen over this period. Estimation of an error correction model shows that the extent of convergence of actual house prices to their long‐run equilibrium path has weakened somewhat since the global financial crisis while the speed of convergence has slowed, indicating structural changes in the Korean housing market. Finally, a forecast for house prices over the next several years suggests that they are unlikely to rise as sharply as they did in the 2000s, given the likely changes in the macro‐financial environment, and that their future path will be closely associated with that of the household debt‐to‐income ratio.

An evaluation of incentive regulation: Corrections

This note re-estimates our model of the determinants and impacts of cost component incentive regulation using an improved data set which avoids double-counting firm observations. It also tests alternative specifications of the relationships. While cost component incentive regulation improves engineering efficiency (heat rates), it does not improve economic efficiency. Thus, our earlier findings are not altered by the smaller data set or by model respecification.     

How an Economic Recession Affects Qualitative Entrepreneurship: Focusing on the Entrepreneur's Exit Decision

This study analyzes how an economic recession affects entrepreneurship from a qualitative perspective. We define entrepreneur as a person who takes risks under uncertainty. Based on this definition, an entrepreneur's exit decision is modeled using real options theory to measure entrepreneur's willingness to accept uncertainty. We find that entrepreneurs who entered before a recession exit when their critical revenue stream reaches 0.16 times the average revenue stream value. The equivalent value for entrepreneurs who enter during an economic recession is 0.33 times the average revenue stream. Furthermore, when uncertainty doubles, the exit probability of entrepreneurs who enter during an economic recession is approximately 2.75 times higher than that of entrepreneurs who enter before recession. We conclude that the majority of entrepreneurs who enter during an economic recession are qualitatively disadvantaged, which leads to the overall decrease in qualitative entrepreneurship.

Revenue‐enhancing Trade Liberalization in a Differentiated Duopoly

Existing studies suggest that in developing countries, tax reforms that increase consumption taxes can compensate for shortfalls in revenue from a tariff reduction. However, these revenue‐enhancing tariff–tax reforms have a critical shortcoming—they generally reduce welfare under imperfect competition. This paper shows that tax reforms such as consumption tax reforms do not necessarily have to be implemented to make up for revenue shortfalls from tariff reductions under imperfect competition, because trade liberalization through tariff cuts leads to an increase in government revenue when domestic and imported goods have a high substitutability. This revenue‐enhancing effect of a tariff reduction occurs for a wider degree of product substitutability when initial tariff and consumption tax rates are high. More importantly, we show that even if initial tariff and consumption tax rates are sufficiently low, a tariff reduction still increases government revenue for a low degree of product differentiation under Bertrand competition.     

How CSR Leads to Corporate Brand Equity: Mediating Mechanisms of Corporate Brand Credibility and Reputation

The purpose of this study is to investigate the relationships among corporate social responsibility (CSR), corporate brand credibility, corporate brand equity, and corporate reputation. Structural equation modeling analysis provided support for the hypotheses from a sample of 867 consumers in South Korea. The results showed that CSR has a direct positive effect on corporate brand credibility and corporate reputation. In addition, the results indicate that corporate brand credibility mediates the relationship between CSR and corporate reputation. Moreover, corporate brand credibility mediates the relationship between CSR and corporate reputation. Finally, the relationship between CSR and corporate brand equity is sequentially and fully mediated by corporate brand credibility and corporate reputation. The theoretical and managerial implications of the results and limitations are discussed, and future research directions are suggested.     

Multinationals' Offshore Operations,Tax Avoidance,and Firm‐Specific Information Flows: International Evidence

Using a large sample of multinational enterprises (MNEs) over the period 1999–2009, this study investigates whether and how offshore operations via offshore financial centers (OFCs) impact the extent to which firm‐specific information is incorporated into stock price, relative to common information. Our analyses show that, irrespective of whether a firm is a Type I offshore firm (directly having headquarters registered in OFCs) or a Type II offshore firm (indirectly setting up subsidiaries in OFCs), the amount of firm‐specific information flowing into stock price is lower for offshore firms than for non‐offshore firms. We also find that as offshore firms become more aggressive in their tax avoidance strategies, their stock prices impound a lower amount of firm‐specific information relative to common information. Finally, we find that a strong offshore proclivity also deters firm‐specific information flows, thereby driving up stock price synchronicity. Our results suggest that the opaque and complex nature of business and financial transactions in OFCs, coupled with their institutional characteristics, that is, weak and flexible legal enforcement, zero or extremely low taxation, and low litigation risk, provide offshore firms with not only stronger incentives but also the opportunities and means to adopt opaque disclosure policies and aggressive earnings management.     

Estimating consumer preferences for online music services

This article analyses consumer preferences with regard to important attributes of online music services. Conjoint analysis and a random coefficient discrete choice model using Bayesian approach with Gibbs sampling are used to estimate the preferences. Based on the quantitative results, we use simulation to look at how a new pricing strategy and the threat of legal penalty for file sharing would influence the online music market. Findings include these: estimated willingness to pay for downloading one music file is significantly less than the actual price of the file; consumers are sensitive to longer search and download times for music files and very sensitive to the threat of legal action; and consumers are not sensitive to online music services broadening their catalogues. Finally, the simulation shows that a combination of increased transaction costs for illegal file sharing and lower-priced digital music files would inhibit illegal file sharing and bolster the number of people purchasing music legally from the online services.     

Restaurant experiences triggering positive electronic word-of-mouth (eWOM) motivations

This study empirically examined which restaurant experiences trigger customers to engage in positive electronic word-of-mouth (eWOM), where the quality of restaurant service (food quality, service quality, atmosphere, and price fairness) is the antecedent of eWOM communication. The results of this study suggest that (1) restaurants’ food quality positively influences customers to spread positive eWOM, motivated by their desire to help the restaurant; (2) satisfactory restaurant experiences with service employees triggered positive eWOM, motivated by the need to help the restaurant or to express positive feelings; (3) a superior atmosphere in restaurants elicited positive eWOM motivated by a concern for others; and (4) price fairness in restaurants did not drive restaurant customers toward eWOM. Additionally, this study investigated sources of positive eWOM and types of eWOM media used among opinion leaders in the restaurant industry to enhance the practical implications of the study regarding online marketing. Because of the small number of opinion leaders in the study sample, specifying who the opinion leaders were (the source of eWOM) and the type of eWOM media the opinion leaders used had no effect. Further discussion and implications are provided in the text.
