Collaboration strategy decision-making using the Miles and Snow typology

Engaging in collaboration may be the best way for a firm to enhance its competitive advantages, since this can offer faster access to both resources and capabilities. This study aims to develop a framework for making collaboration partner choice decisions. The authors design a strategic game model of collaboration using Miles and Snow typology. An empirical data set collected from the S&P COMPUSTAT database is adopted to verify the model, and several managerial implications are derived. This model helps a company choose a competitor as a collaborative partner and helps in the selection of a collaboration strategy.

Taking marketing strategy risks with seemingly no expected gains

This paper investigates the competitive rationale for firms to invest in marketing activities aiming to enhance valuation and achieve differentiation and competitive advantage, while carrying the strategic risks of causing unintended negative consequences. We build a stylized theoretical model where firms offering similar (homogenous) products are competing by determining their marketing strategy and pricing. Each firm must choose between several marketing activities that have different potentials of enhancing consumers’ product valuations while carrying some risk of lowering consumer valuation if unintended negative outcomes occur. The stochastic nature of marketing implies that (1) even when both firms invest the same amount of money aiming to enhance product valuations by the same level, there will be a variety of (posterior) vertical differentiation scenarios where the consumers could value either firm’s product as better as or worse than the rival’s. (2) The firms may employ marketing activities that do not even lead to gains in consumer product valuation in expectation. The duopoly model analysis indicates that associated with strategic pricing, even such stochastic marketing activities may constitute desirable strategies for two a priori symmetric firms in order to avoid a Bertrand type competition as the benefit from differentiation is found to be significant enough to offset the unintended negative outcomes. The oligopoly model analysis indicates that there is an increased incentive to take marketing risk when there is a greater level of competitive intensity in the marketplace. Preliminary experimental evidence is presented to support the main findings from theoretical model analyses. The paper thus provides important managerial implications for firms contemplating investment in seemingly risky marketing activities.

     

Effects of cross-border capital flows on stock returns of dual-listed firms in mainland China and Hong Kong: Evidence from a natural experiment

This study analyses the effects of the Shanghai–Hong Kong Stock Market Connect policy on the price disparity between A-shares and H-shares of dual-listed companies (DLC). Using a difference-in-difference estimation method, we show that the policy decreases the relative twin cumulative abnormal returns of treated DLC by 3% and narrows the price gaps between A-shares and H-shares. We determine that the rising demand for H-shares, which are newly accessible by mainland investors, drives the price of H-shares up. By contrast, the price of A-shares remains unchanged. Further analysis reveals that cross-border capital flow is the main force of the policy.     

Data-driven tree structure for PIN models

Probability of informed trading (PIN) models characterize trading with certain types of information through a tree structure. Different tree structures with different numbers of groups for market participants have been proposed, with no clear, consistent tree used in the literature. One of the main causes of this inconsistency is that these trees are artificially proposed through a bottom-up approach rather than implied by actual market data. Therefore, in this paper, we propose a method that infers a tree structure directly from empirical data. More precisely, we use hierarchical clustering to construct a tree for each individual firm and then infer an aggregate tree through a voting mechanism. We test this method on US data from January 2002 for 7608 companies, which results in a tree with two layers and four groups. The characteristics of the resulting aggregate tree are between those of several proposed tree structures in the literature, demonstrating that these proposed trees all reflect only part of the market, and one should consider the proposed empirically driven method when seeking a tree representing the whole market.

     

Comparative persistence and adherence with newer anti-hyperglycemic agents to treat patients with type 2 diabetes in the United States

Objectives: Non-adherence and non-persistence to anti-hyperglycemic agents are associated with worse clinical and economic outcomes in patients with type 2 diabetes. This study evaluated treatment persistence and adherence across newer anti-hyperglycemic agents (canagliflozin, dapagliflozin, sitagliptin, saxagliptin, linagliptin, liraglutide, or exenatide).

Methods: This retrospective cohort study of Truven Health Analytics Marketscan databases included adult patients with type 2 diabetes whose first pharmacy claim for a newer anti-hyperglycemic agent was between February 1, 2014 and July 31, 2014. Treatment persistence and adherence were assessed for 12 months after the first claim (post-index). Persistence was defined as no gap ≥90 days between the end of one pharmacy claim and the start of the next pharmacy claim post-index. Adherence used two definitions: proportion of days covered (PDC) and medication possession ratio (MPR). Multivariable analyses of non-persistence (hazard ratios) and adherence (odds ratios) were adjusted for baseline demographics, drug cost, clinical characteristics, and other anti-hyperglycemic agents.

Results: A total of 11,961 patients met all study selection criteria. Persistence rates at 12 months were significantly greater (p?p?=?0.83; PDC?=?0.79) and canagliflozin 300?mg (MPR?=?0.92; PDC?=?0.81) were greater than for the other index anti-hyperglycemic agents (MPR?=?0.33–0.75; PDC?=?0.33–0.72). Consistent results for treatment persistence and adherence were observed in multivariable analyses that were adjusted baseline characteristics.

Conclusions: Canagliflozin was associated with better treatment persistence and treatment adherence compared with other anti-hyperglycemic agents in real-world settings.     

Timing earnings

Since the opening of China’s securities market, there have been a number of bull and bear cycles. This paper discusses how executives use the market timing approach to manage earnings in different cycles to maximize firm value. We find that Chinese listed companies choose to release more earnings during bull markets and this phenomenon is more evident in companies that are more profitable and have higher valuations. We also find that executives who do not release more earnings during bull markets are more likely to be dismissed.

How group efficacy mediates the relationship between group affect and identification

This study examines the mediating role of group efficacy on the relationship between group affect and group identification by integrating the collective cognition process. Using a sample of forty-seven work groups in Study 1, the results show that group efficacy fully mediates the relationship between positive and negative group affect and group identification. Study 2 applies a two-wave panel design to verify the impact of group efficacy on group identification. The results of Study 2 indicate that group efficacy relates positively to the development of group identification. The implications for theory and practice are discussed.
