When examining the tariff-jumping effect, the literature emphasizes the cost-induced effect, which states that a foreign firm has an incentive to jump over the tariff wall in order to locate in a foreign territory, and thereby escape tariffs. The authors set up a location model to show what they refer to as the location-induced effect on tariff-jumping. This location-induced effect, together with the traditional cost-induced effect, makes tariff-jumping more (less) likely to take place when the production function in question exhibits decreasing (increasing) returns to scale. 相似文献
Academics and practitioners have frequently debated the relationship between market capitalization and expected return. We apply the Markowitz efficient frontier approach to develop a portfolio performance measure that compares the return of a portfolio to its optimal return, using data from the UK stock market over the period 1985–2012. Our results show that there is a negative relationship between portfolio size and portfolio return during the period under study. When comparing actual portfolio return with achievable return for the same level of risk, we find that as the portfolio size expands, underperformance of the portfolio increases, i.e. the larger the portfolio size, the greater the underperformance. This indicates that Markowitz efficiency is difficult to achieve, particularly in large portfolios. Changing model parameters leads to alternative efficient frontiers that impact upon the measurement of performance. However, the use of alternative efficient frontiers does not affect our result of the size effect on the relative performance of portfolios. Our study shows that the size effect is present over the full period. Our findings also suggest that the excess returns found in small portfolios are likely to be associated with higher levels of diversifiable risk in comparison with larger portfolios. Furthermore, in contrast to other studies, we find no evidence to support the size reversal effect in the data. 相似文献
This study examines a foreign firm's entry decision and its effects on the host country's welfare in a model with a composite good in which both commodity and service generate utility for consumers. Along with the commodity it produces, a producer can provide the service by itself or outsource the service. The result shows that the incentive for foreign direct investment (FDI) in the service sector increases under liberalising trade in the final‐good market. Moreover, there exist policy combinations of trade and investment liberalisation, whereby the domestic firms' profitability is traded off with the host country's social welfare when the foreign firm provides a service through FDI or through outsourcing, respectively. Finally, the welfare after simultaneously liberalising trade and investment is not necessarily greater than that under autarky. 相似文献
Since the enactment of Pension Protection Act of 2006, lifecycle funds that reduce exposure to stocks with age have rapidly replaced money market funds as the most commonly nominated default investment options for participant-directed retirement plans. We examine their appropriateness in meeting a threshold level of retirement wealth required by plan participants. Using a utility function motivated by prospect theory (Kahneman and Tversky, 1979), we show that whilst lifecycle funds are vastly superior to money market funds (except for very low thresholds), they rank below balanced funds that maintain constant exposure to equities over time. As thresholds increase, lifecycle funds are also dominated by funds that switch assets conditional to prior investment performance. Even in the absence of a minimum threshold wealth level, lifecycle funds do not emerge as the most preferred choice among the investment options considered by our paper. 相似文献
This paper examines the welfare effect of third-degree price discrimination in a vertically related market with one upstream monopolist that sells its input to a continuum of downstream markets. Assume that the market boundary of the monopolist is endogenously determined. It is found that social welfare is necessarily lower under discriminatory than uniform pricing, even if the market area of the former is greater than that of the latter. This finding is contrary to that in the extant literature on price discrimination in final goods markets. 相似文献
Opinion leaders are the people in a social network who have the greatest influence on other people's acknowledgment or adoption of products/services in the diffusion process of technological innovation. In this research, we investigate which opinion leader is the best marketing choice in terms of diffusion speed and maximum cumulative number of adopters, using a social network approach and threshold model. On the basis of the simulation result, we find that opinion leaders with high sociality are the best ones for fast diffusion, whereas those with high distance centrality are the best ones for the maximum cumulative number of adopters. Moreover, we conclude that the characteristics of effective opinion leaders selected as initial adopters could vary depending on the characteristics of the social network and type of innovation. Finally, we find that opinion leaders affect the diffusion process only when the percentage of initial adopters reaches a critical mass. 相似文献
Although business model innovation has received increasing attention in recent years, there are gaps in existing literature concerning why innovation occurs. Drawing on the intentions model and knowledge-based view, this study explores the relationship between entrepreneurial alertness and business model innovation, proposing a moderated mediation framework to handle the questions of why some entrepreneurs achieve business model innovation successfully while others do not. Based on a dataset of 150 firms in northwest China, this study finds that (1) entrepreneurial alertness facilitates business model innovation; (2) explorative learning and exploitative learning mediate the relationship between entrepreneurial alertness and business model innovation; and (3) risk perception moderates the mediating effects of different types of learning and then affects the relationship between entrepreneurial alertness and business model innovation. Specifically, with the increase of risk perception, the mediating role through explorative learning is weakened, while the mediating effect through exploitative learning is enhanced.
Background music adds a multisensory element to marketing and e-commerce. Applying interactive sensory-enabling technologies (SETs) to online shopping websites is an area of interest in sensory marketing. This research examines interactive background music in e-commerce and investigates how online consumer involvement moderates the effects of interactive music. Single-factor experiments with three conditions (interactive music, static background music, and control) were conducted to investigate its impact on experiential value, cognitive value, and purchase intention of high- and low-involvement consumers among both students (Study 1, N = 251) and nonstudent samples (Study 2, N = 218). Different music genres were applied to stimuli of the two studies to demonstrate the generalizability of the findings. Results find that interactive music enhances the experiential value of e-commerce for low-involvement consumers. By contrast, high-involvement consumers show greater purchase intention under the interactive music condition due to a heightened level of perceived cognitive value. Involvement is an effective predictor of elaboration and purchase intention under the interactive music condition, but not under the other two conditions. The contribution is twofold: (a) it shows the impact of music as an interactive SET and, (b) demonstrates the moderating role of consumer involvement in the context of multisensory integration in e-commerce. Theoretical and practical implications are discussed along with limitations and directions for future research. 相似文献
We investigate the determinants of currency invoicing in trade using import and export transactions data between Korea and its 30 major trading partners from 2000 to 2013. We find a noticeably different pattern of currency invoicing from advanced countries. For example, a large market share of Korean exporters in partner countries does not guarantee more use of the Korean won in currency invoicing. This might be attributed to a low degree of Korean won's internationalisation and the strong coalescing effect. We also observe that the higher the level of industry product differentiation, the weaker the coalescing motive. In addition, we verify that the share of invoicing in the currency of Korea's trading partner tends to be higher when the partner country has (i) a larger trade volume, (ii) higher level of financial development, (iii) lower inflation and lower price volatility and (iv) its own currency with lower transaction costs. 相似文献
