International innovation and strategic initiatives: A research agenda

Despite the argument that leveraging the expertise of foreign subsidiaries to the global firm benefits the whole firm's competitive advantage, in the case of international innovation, such leveraging rarely takes place. We investigate this paradox, applying research on strategic initiatives to the context of international R&D. Developing a conceptual model on the basis of communication psychology, we analyse how the innovative expertise of R&D subsidiaries may be leveraged to benefit the global firm. Specifically, we determine six elements whose greater exploration can lead to a deeper understanding of how the innovation expertise of a foreign R&D subsidiary may be leveraged.     

Strategy research: governance and competence perspectives

Business strategy is a complex subject and is usefully examined from several perspectives. This paper applies the lenses of governance and competence to the study of strategy. Both the governance and the competence perspectives have had the benefit of distinguished antecedents. They have also had to deal with tautological reputations. I begin with the governance perspective, with emphasis on the six key moves through which it has been operationalized. I then examine the competence perspective in these same six respects. Governance challenges the competence perspective to apply itself more assiduously to operationalization, including the need to choose and give definition to one or more units of analysis (of which the ‘routine’ is a promising candidate). The research challenges posed by competence to which governance can and should respond include dynamic transaction costs, learning, and the need to push beyond generic governance to address strategy issues faced by particular firms (with their distinctive strengths and disabilities). A lively research future for these two perspectives, individually and in combination, is projected. Copyright © 1999 John Wiley & Sons, Ltd.     

How managers protect intellectual property rights in China using de facto strategies

Foreign firms trying to protect their intellectual property rights (IPRs) in emerging economies are suffering real pressures because these economies usually offer little or no enforcement of IPR. Foreign firms therefore have to resort to approaches unlike those they use in developed countries. This paper explores what managers of foreign firms in China have already tried in their efforts to achieve effective IPR protection – specifically, they have crafted de facto strategies that can protect IPR without using China's legal system or engaging in lawsuits against imitators. These strategies work, and this paper explains how and why, thus offering a potential template for IPR protection in other economies with weak appropriability systems.     

An improved bootstrap test of stochastic dominance

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have asymptotic sizes that are less than or equal to the nominal level uniformly over probabilities in the null hypothesis under regularity conditions. This paper also characterizes the set of probabilities so that the asymptotic size is exactly equal to the nominal level uniformly. As our simulation results show, these characteristics of our tests lead to an improved power property in general. The improvement stems from the design of the bootstrap test whose limiting behavior mimics the discontinuity of the original test’s limiting distribution.     

Transaction cost economics and its uses in marketing

Scholarship at the intersection of transaction cost economics (TCE) and marketing has enjoyed an impressive record of growth over the past three decades, and the future promises more of the same. Following Erin Anderson’s perceptive uses of TCE in her 1982 dissertation, the field of marketing has made many constructive uses of and contributions to TCE, where the latter include broadening the reach of TCE, posing important challenges, and identifying opportunities still to be addressed. Given this history, we advance the proposition that the relation between TCE and marketing has been and should be a two-way street. In considering the scope for future research, we give special attention to issues of asymmetric costs, the dynamics of governance, and disequilibrium contracting. We also discuss the four precepts of pragmatic methodology, with special emphasis on prediction and empirical testing. The Appendix provides added perspective on the evolving “science of organization” of which TCE is a part.     

From Returns to Tweets and Back: An Investigation of the Stocks in the Dow Jones Industrial Average

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.     

The Impact of Search and Recommendation Systems on Sales in Electronic Commerce

The Internet and related technologies have vastly expanded the variety of products that can be profitably promoted and sold by online retailers. Furthermore, search and recommendation tools reduce consumers’ search costs in the Internet and enable them to extend their search from a few easily found best-selling products (blockbusters) to a large number of less frequently selling items (niches). As a result, Long Tail sales distribution patterns emerge that illustrate an increasing demand in niches. We show in this article how different classes of search and recommendation tools affect the distribution of sales across products, total sales, and consumer surplus. We hereby use an agent-based simulation which is calibrated based on real purchase data of a video-on-demand retailer. We find that a decrease in search costs through improved search technology can either shift demand from blockbusters to niches (search filters and recommendation systems) or from niches to blockbusters (charts and top lists). We break down demand changes into substitution and additional consumption and show that search and recommendation technologies can lead to substantial profit increases for retailers. We also illustrate that decreasing search costs through search and recommendation technologies always lead to an increase in consumer surplus, suggesting that retailers can use these technologies as competitive advantage.     

Consistent estimation of a general nonparametric regression function in time series

We propose an estimator of the conditional distribution of X_t|X_t−1,X_t−2,…, and the corresponding regression function , where the conditioning set is of infinite order. We establish consistency of our estimator under stationarity and ergodicity conditions plus a mild smoothness condition.     

Gas storage valuation under limited market liquidity: an application in Germany

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices.
