This study seeks to inform investment academics and practitioners by describing and analyzing the population of return predictive signals (RPS) publicly identified over the 40-year period 1970–2010. Our supraview brings to light new facts about RPS, including that more than 330 signals have been reported; the properties of newly discovered RPS are stable over time; and RPS with higher mean returns have larger standard deviations of returns and also higher Sharpe ratios. Using a sample of 39 readily programmed RPS, we estimate that the average cross-correlation of RPS returns is close to zero and that the average correlation between RPS returns and the market is reliably negative. Abstracting from implementation costs, this implies that portfolios of RPS either on their own or in combination with the market will tend to have quite high Sharpe ratios. For academics who seek to document that they have found a genuinely new RPS, we show that the probability that a randomly chosen RPS has a positive alpha after being orthogonalized against five (25) other randomly chosen RPS is 62 % (32 %), suggesting that the returns of a potentially new RPS need to be orthogonalized against the returns of some but not all pre-existing RPS. Finally, we posit that our findings pose a challenge to investment academics in that they imply that either US stock markets are pervasively inefficient, or there exist a much larger number of rationally priced sources of risk in equity returns than previously thought. 相似文献

Aided by the exponential rate of globalization and digitalization, reward or loyalty programs (LPs) have attained global reach. Paradoxically, however, dropout rates of LPs have averaged over 75%. This disconcerting statistic, coupled with the lack of culture-specific insights in the literature, points to a research area of great theoretical and practical importance. To address the aforementioned issues, we develop a culture-based and progress-based model of consumer motivation that is especially applicable to LP members. Drawing on cross-cultural literature and goal pursuit theory, our research enriches a field that is inherently global in nature. Through a series of research propositions that elucidate how Western individualist (vs. Eastern collectivist) consumers are differentially motivated to pursue LP rewards, we advance theoretical understanding of reward-induced behavior across cultures and offer useful insights for global managers of LPs. 相似文献

Location advantages and subsidiaries’ R&;D activities in emerging economies: Exploring the effect of employee mobility 总被引:3,自引:3,他引:0
With multinational corporations increasingly seeking subsidiaries’ specific advantages in foreign countries to develop their
innovative capabilities, internationalization of research and development has been greatly emphasized. However, in emerging
economies, managers are encountering the challenge of high employee mobility under the weak intellectual property protection
regime. This article investigates subsidiaries’ employee mobility and proposes that it negatively moderates the relationship
between location advantages and the level of subsidiaries’ R&D. This article extends R&D internationalization and enhances
current understanding of subsidiaries’ R&D activities. Further, it provides managerial implications as to how managers can
improve R&D outcome by mitigating obstacles in emerging economies.

Pioneering advantage in manufacturing firms has received much attention in the management and marketing literature. Few research studies, however, have been conducted to investigate the pioneering advantages and disadvantages involved in new service development, especially across several geographic regions. We build a theoretical framework of pioneering advantage in service industries based on the distinguishing characteristics of services. From this framework, we develop a set of testable propositions about the importance of several types of pioneering advantage (economic, preemptive, technological, and behavioral advantages) to service managers. Specifically, we propose that all of these types of pioneering advantages are important to service managers, and that these managers perceive that pioneering results in improved firm performance. We also propose that, due to the distinguishing characteristics of services such as intangibility and heterogeneity, service managers will not perceive the risks of pioneering in a service industry to be severe. In addition, we propose that certain types of pioneering advantage will be more important to service managers in Western countries than in Asian Pacific countries due to cultural and business environmental differences. In particular, we propose that service managers from Western firms perceive preemptive advantages of pioneering to be more important than do their Asian Pacific counterparts, and service managers from Asian Pacific firms perceive behavioral advantages of pioneering to be more important than do their Western counterparts. To test our propositions empirically, we develop a set of pioneering principles from the literature. We then collect and analyze data from a sample of 982 senior managers in service industries from nine countries: the United States, the United Kingdom, Germany, Japan, China, Taiwan, Hong Kong,1 South Korea, and Singapore. We find evidence of several significant cross‐cultural differences consistent with our propositions. In fact, seven of the eight propositions are strongly or partially supported. The only nonsupported proposition concerned the importance of technological advantage. We find that technological advantages of pioneering are much less important to service managers than are other pioneering advantages. We conclude with strategic recommendations for managers involved in new service development and international or global competition, and provide directions for future research. We note that the insights from this study can help managers from both the West and the Asian Pacific region to better understand their global competitors who pursue a new service pioneering strategy, and can potentially help them select entry deterrence strategies more effectively. 相似文献

Summary. Price bubbles in an Arrow-Debreu equilibrium in an infinite-time economy are a manifestation of lack of countable additivity of valuation of assets. In contrast, the known examples of price bubbles in a sequential equilibrium in infinite time cannot be attributed to the lack of countable additivity of valuation. In this paper we develop a theory of valuation of assets in sequential markets (with no uncertainty) and study the nature of price bubbles in light of this theory. We define a payoff pricing operator that maps a sequence of payoffs to the minimum cost of an asset holding strategy that generates it. We show that the payoff pricing functional is linear and countably additive on the set of positive payoffs if and only if there is no Ponzi scheme, provided that there is no restriction on long positions in the assets. In the known examples of equilibrium price bubbles in sequential markets valuation is linear and countably additive. The presence of a price bubble means that the dividends of an asset can be purchased in sequential markets at a cost lower than the asset's price. We present further examples of equilibrium price bubbles in which valuation is nonlinear, or linear but not countably additive. 相似文献

Several previous studies have investigated the effects of creativity and knowledge on innovation, both of them being considered prerequisites of innovation. However, the relationship among the different variables can be confusing due to redundant causality. In this paper, we study the influence of the mediating effect of creativity between breadth of knowledge (diverse sources of knowledge) and innovation by developing a conceptual model, and then test it on the Spanish ceramic cluster of Castellón. Empirical findings show that creativity is the mechanism through which the different sources of knowledge influence innovation. The implications of these results in relation to creativity, knowledge and innovation theory and practices are discussed. 相似文献

This paper contributes to the recent research on “export sophistication,” or the composition of a country's export portfolio. The central question of the current study is what determines a country's level of export sophistication. I argue that a synergetic relationship between state and society positively contributes to the level of export sophistication. The logic behind the argument is that the socially optimal level of investment in new products can only be realized if both the firm and the government find it individually profitable to carry out the investment. In cases whereby either or both lacks private incentive to invest, higher synergy between public and private sectors makes such joint investments more likely to occur. This logic is formally illustrated using a simultaneous game with incomplete information. The central hypothesis is tested using time series cross‐sectional data. The key empirical novelty of this paper is the construction of a “synergy index” based on Peter Evans' conceptualization of the term. Overall, the data give good support to the hypothesis. This relationship is particularly robust for the subsample of countries with intermediate levels of synergy. Furthermore, there is evidence suggesting that state‐society synergy is subject to diminishing returns as its values get higher. 相似文献
