Towards a Social Theory of Agency

We challenge critics of agency theory who suggest that agency theory's value does not extend outside a narrow context dominated by egocentric agents seeking only to maximize wealth at the expense of the principal. Instead, we argue that agency theory's flexibility allows for its application to a variety of non‐traditional settings where the key elements of agency theory, such as self‐interest, information asymmetry, and the mechanisms used to control agency costs can vary beyond the narrow assumptions implied in traditional agency‐based research. We suggest that extending agency theory to diverse settings using a deductive approach can be accomplished by formally recognizing and incorporating the institutional context surrounding principal–agent (P–A) relations into agency‐based models. Thus, criticisms that agency theory fails to acknowledge the social context in which P–A relations occur provides not a barrier but an opportunity for extending our understanding of P–A relations to a variety of diverse contexts.     

Dynamic competitive retail pricing behavior with uncertainty and learning

When competing retailers lack full information about rivals' decision processes, how will dynamic pricing behavior vary from patterns observed in more traditional static or full-information models? We investigate this question in a dynamic alternating-moves duopoly model. Retailers update (linear) conjectures about rivals' future prices in a Bayesian fashion. We show that as observed and expected prices converge, a pricing equilibrium is always achieved, whether or not the conjectured and actual values of the slope of the rival's best response function are consistent. Assuming specific parameter values, we compare equilibrium prices and associated profits in our Bayesian learning model with those obtained under the assumptions of static Nash behavior, collusive behavior and dynamically optimal behavior with full information. We apply the notions of strategic substitutability and strategic complementarity to the analysis and find that when products are strategic complements, conjectures of higher rival price responsiveness lead to higher steady-state prices and profits. The reverse is true for strategic substitutes. We also find that learning about a rival's behavior proceeds more quickly, the less intensely related in demand are products. We find, in general, that equilibrium pricing patterns and profits can vary considerably from those in full-information environments, but that even with grossly wrong beliefs about rival behavior, competing retailers are still attracted to an equilibrium. The analysis suggests not only the value of investigating lessthan-full information situations but also the potential incremental value of signalling greater or less aggressiveness than truly characterizes one's behavior as a strategic option.     

Optimal pricing strategy for foreign market entry: a game theoretic approach

Given that pricing plays an important role in a company's international competitive strategy, researchers have long argued the need for theory building in the area of international pricing. This study develops an optimal pricing strategy for foreign market entry using a game theoretic framework. The proposed model assumes two firms, a local incumbent and a foreign entrant, competing in a market. Consumers know the quality of the incumbent's offering, but do not know how it compares to that of the foreign entrant's. Based on these assumptions, and using the theory of inference making, we propose an upward price distortion by the entrant firm as an optimal entry strategy under incomplete information. The paper presents a game theoretic derivation to establish that the game has a unique intuitive separating equilibrium where the entrant firm stands to gain by engaging in upward price distortion to signal high quality to consumers.

Endogenous vertical structure and trade policy in an import-competing market

We examine the endogenous determination of a vertical market in an import-competing market with import tariff. We show that if firms commit to vertical organization before the government's commitment to trade policy, the home and foreign firms choose vertical separation and vertical integration, respectively, at equilibrium under Bertrand competition. Under Cournot competition, the subgame perfect Nash equilibrium entails both firms separating their retailers. Comparing profits between Bertrand competition to Cournot competition, we find that upstream manufacturer's profit can be higher under Bertrand competition with integration than under Cournot competition with separation when comparing foreign upstream manufacturer's profit.     

Corporate investments and growth options

Real options theory models certain corporate investments as investments in growth options, yet there is little direct evidence on whether firms actually capture growth option value from these investments. In the current paper, we attempt to bridge this empirical gap, and we also examine the conditions under which the growth option value embedded in such investments is enhanced. Results from a sample of manufacturing firms during 1989–2000 reveal that investments in research and development and joint venture (JV) investments contribute to firms' growth option values. We also show that, among JVs of different ownership structures, only minority JVs increase growth option value. Our findings affirm options theory's assertion that real options can help firms capture valuable upside opportunities, they highlight the value of examining contingencies that drive option value, and they also point to the challenges firms face in realizing the unique benefits the theory emphasizes.

Do social media enhance constructive employee voice all of the time or just some of the time?

Social media are becoming widely adopted by organisations to encourage collaboration and communication. We seek to understand how social media can enhance employee voice and employees' willingness to engage in constructive dialogue with both colleagues and managers. By drawing on literature on employee voice, signalling theory and personal control to analyse qualitative data from research into three strategic business units in a major global telecommunications corporation, we find that (a) employee perceptions of personal control and autonomy influence whether and how employees' exercise voice through social media, and (b) these perceptions vary according to different organisational/field‐level contexts evident in the corporation.     

Human Resource Systems and Ethical Climates: A Resource‐Based Perspective

We know very little about how ethical climates are built and the potential role of a firm's HR system in facilitating the development of this resource. The resource‐based view (RBV) of the firm suggests that human resource systems directly influence a firm's performance through the development of resources that are deeply woven in a firm's history and culture. How this occurs though has not been thoroughly considered in the research literature. Drawing on the theoretical insights from the resource‐based view of the firm, this article explores how HR systems can foster the development and maintenance of five types of ethical climates. In so doing, this article improves our conceptual understanding of why ethical climates may be seen as having strategic value for firms and how HR systems may influence that value. In addition, it contributes to theory by extending the domain of the resource‐based view of the firm by exploring its integration with the varied types of ethical climates. © 2014 Wiley Periodicals, Inc.     

Empirical labor search: A survey

This paper surveys the existing empirical research that uses search theory to empirically analyze labor supply questions in a structural framework, using data on individual labor market transitions and durations, wages, and individual characteristics. The starting points of the literature are the Mincerian earnings function, Heckman's classic selection model, and dynamic optimization theory. We develop a general framework for the labor market where the search for a job involves dynamic decision making under uncertainty. It can be specialized to be in agreement with most published research using labor search models. We discuss estimation, policy evaluation with the estimated model, equilibrium model versions, and the decomposition of wage variation into factors due to heterogeneity of various model determinants as well as search frictions themselves. We summarize the main empirical conclusions.     

Voluntary Assurance of Voluntary CSR Disclosure

We study a firm's decisions to engage in socially responsible activities, voluntarily report on them, and purchase external assurance of the report. In our signaling model, neither firm type nor the level of activity is observed. We show that if voluntary assurance is not too expensive, the firm that engages in more socially responsible activities purchases external assurance and thus “selects” a separating equilibrium. As a result, CSR reports can be used to infer the level of activity and this causes all firms to engage in more socially responsible activity. Further, when voluntary assurance is required to support a separating equilibrium, greater monitoring by social activists increases the chosen quality of voluntary assurance—voluntary assurance and monitoring by social activists are complements, not substitutes.     

Improving resilience of the healthcare supply chain in a pandemic: Evidence from Europe during the COVID-19 crisis

The severe scarcity of critical medical supplies caused by the COVID-19 pandemic led to considerable procurement challenges in the healthcare supply chain (HCSC). As ensuring the availability of such supplies during disruptions is critical, the debate on how to increase supply chain resilience in healthcare has gained new momentum. We present empirical evidence from a multi-tier case study spanning nine European medical supplies manufacturers and hospital groups. Based on the resource dependence theory, we investigated procurement-related strategies to improve medical supplies availability. We conducted semi-structured interviews with 39 procurement and supply chain management experts and derived seven propositions on buffering and bridging approaches for managing evolving resource dependencies and thereby strengthening supply chain resilience in a pandemic. Overall, we confirm the resource dependence theory's applicability for explaining companies' mitigation measures in a pandemic disruption. We find that bridging measures within the healthcare supply base, such as offering procurement support for suppliers or leveraging long-term buyer-supplier relationships, are more effective for securing medical supplies than buffering measures. Complementing bridging with buffering, such as extended upstream procurement or resource sharing among hospitals, can lead to superior risk mitigation as capacities of the present supplier base may not suffice. Furthermore, we extend the resource dependence theory by showing that the severity of disruptions caused by a pandemic triggers new forms of buffering external to the HCSC. Both traditional and new buffering measures establish novel flows of medical supplies in the HCSC that can enable higher supply security in a pandemic.     

Simultaneous search with heterogeneous firms and ex post competition

In this paper we study the allocation of workers over high and low productivity firms in a labor market with coordination frictions. Specifically, we consider a search model where workers can apply to high and or low productivity firms. Firms that compete for the same candidate can increase their wage offers as often as they like. We show that if workers apply to two jobs, there is a unique symmetric equilibrium where workers mix between sending both applications to the high and sending both to the low productivity sector. But, efficiency requires that they apply to both sectors because a higher matching rate in the high-productivity sector can then be realized with fewer applications (and consequently fewer coordination frictions) if workers always accept the offer of the most productive firm. However, in the market the worker's payoff is determined by how much the firm with the second highest productivity is willing to bid. This is what prevents them from applying to both sectors. For many configurations, the equilibrium outcomes are the same under directed and random search so our results are not driven by random search. We discuss the effects of increasing the number of applications and show that our results can easily be generalized to N-firms.     

Postsearch uncertainty,product heterogeneity,and price divergence

We develop a consumer search model in which consumers may remain uncertain about product quality even after inspecting the product. We first consider the postsearch uncertainty regarding vertical quality, and characterize the separating equilibrium in which firms with different quality levels charge different prices. If quality information is not sufficiently transparent after the search, then prices between the low- and the high-quality products can either diverge or converge as the search cost decreases, depending on the degrees of horizontal and vertical product differentiation. We further extend the model to include the postsearch uncertainty about the horizontal match value and to endogenize the firm's quality choice.     

Managerial quality,financial structure and signalling: A test of pricing efficiency in the UK equity securities market

This paper seeks to ascertain if stock market pricing procedures are operationally efficient in setting prices so as to discriminate against poor-quality management. Signalling theory suggests management's leverage decision as the means by which managerial quality can be identified. Departures from average leverage, given firm characteristics, are interpreted as indicating managerial quality. Ordinary least-squares regression analysis is used to identify these departures, and to test if shareholders' yields are responsive to them. The results are not always statistically significant, but do provide some support for the signalling hypothesis and for the efficiency of UK security pricing.     

Stressing affordances: Towards an appraisal theory of technostress through a case study of hospital nurses' use of electronic medical record systems

Nurses use electronic medical record (EMR) systems to accomplish a variety of care-related tasks. Nurses, therefore, encounter a range of stressful situations and events related to using EMR systems, a phenomenon known as technostress. Previous research suggests that individuals appraise technostress differently. However, not much is known about the appraisal process of technostress. By integrating the literature on technostress, affordances, and appraisal theory, this paper introduces the appraisal theory of technostress, which is developed empirically through an interpretive case study involving interviews with hospital nurses. The appraisal theory of technostress explains how individuals process and appraise information about how to potentially act on technology-related stressful events through a system's features. Information about the event, and information about the action potential afforded by the system's features, is evaluated through an appraisal process that includes three appraisal checks: goal relevance, goal conduciveness, and value compatibility. The appraisal checks verify whether the action possibilities of the system's features align or misalign with an individual's goals and values related to action, and shape how the event and the system's features are appraised as challenge or hindrance techno-stressors. Overall, the study offers a novel theoretical perspective and methodological approach to conceptualizing and investigating technostress. More detailed contributions to research and practice are also discussed.     

Little Firms and Big Patents: A Model of Small‐Firm Patent Signaling

Patent strategies of small technology‐intensive firms are difficult to explain with standard incentive arguments based on intellectual property rights. This paper develops a rationale for patent filing as a disclosure strategy. We develop a two‐sender signaling game to study patenting incentives of two technology start‐ups to file in a large‐scale patent system with the goal to attract a user firm. Both start‐ups may decide to invest in costly modification of their patent application before filing. The paper identifies a separating equilibrium in which the high‐quality inventor files and so separates from its technology competitor. Of particular interest is the study of pooling and semi‐separating equilibria, as well as the impact of subsidies. We find that a higher quality of a country's inventions, reflected in the possible innovative steps and thus in higher expected profits for foreign user firms, may increase the chance of the relatively lower‐quality inventor to enter international technology markets.     

Effects of two national environmental factors on e-commerce functionality adoption: a cross-country case study of a global bank

In order to offer new services and gain competitive advantages, e-commerce has been widely adopted, particularly in the banking industry. Unfortunately, despite the growing adoption of e-commerce in the banking industry, the issue that web-based B2C e-commerce functionality adoption varies between banks or a bank's branches across nations has not received sufficient attention. Many factors affect e-commerce functionality adoption. However, two national environmental factors (information infrastructure and demographics) are particularly important because they relate to the availability of technologies in use and the characteristics of customers, respectively. This research conducts a cross-country case study of a global bank's Beijing (China), Chicago (USA), and Dubai (UAE) branches to investigate how the two national environmental factors affect e-commerce functionality adoption. The specific objectives are to discover how information infrastructure (measured by number of PCs per 1000 people and Internet access cost) and demographics (measured by population composition and income) affect e-commerce functionality adoption of the global bank's three branches. Secondary data were collected for information infrastructure and demographics; additionally, focused interviews with these three branches' IT and business managers provided sources for answering ‘how’. The key finding demonstrates that the differences in e-mail ordering and online shopping adoptions between these branches are mainly attributed to proposed factors of population composition and Internet access cost, and the new factor of individual credit reference system. This research contributes to theory development in this emerging important research subject.     

Flow Signals: Evidence from Patent and Alliance Portfolios in the US Biopharmaceutical Industry

Integrating signalling theory and the portfolio diversity literature, we theorize that diversity in a firm's patent and alliance portfolios sends contrasting flow signals impacting its market value in a nuanced way. Diversity in an alliance portfolio mediates the patent portfolio diversity – market value relationship by suppressing the negative effect of patent portfolio diversity creating an overall positive effect. We test our mediation model on a longitudinal set of 225 US biopharmaceutical firms that were awarded 17,078 patents and participated in 37,744 alliances between 1990 and 2006. Our theory and findings contribute three novel insights. First, we demonstrate the value of a temporal lens in explaining why diversity in a firm's patent and alliance portfolios send flow signals that establish expectations among market observers and have performance implications. Second, establishing that patent and alliance portfolio diversity are temporally sequenced provides compelling evidence for the value of studying multiple types of portfolios, their temporal relationships and effects on firm outcomes. Third, since diversity in a firm's portfolios can send contrasting flow signals conditioned on the cognitive demands and proximity involved in interpreting the signals, firms that do not maintain a ‘signalling fit’ with market observers increase the probability of unintentional negative signalling effects.     

A network approach to work-family conflict

Most human behaviours, including those instrumental for reducing Work–Family Conflict (WFC), take place in the context of social relationships. However, the role of social networks in an individual's WFC goal pursuit process has not received sufficient attention, as most current research is dominated by an agentic perspective that argues that individuals possess the capabilities to change the demands and resources associated with their roles freely. We believe that the reality faced by many workers is more composite, as the various work and family stakeholders present in an individual's network can create significant constraints and opportunities that are capable of inhibiting or enhancing their agency. In this paper, we aim to examine how the ecosystem of network relationships in an individual’ social network can influence his or her overall capability to minimise WFC. Building on insights from dynamic network theory, a recently introduced framework in the social network literature, we propose a conceptual model that explains the specific roles that work and family stakeholders (i.e., supporters, preventers, resistors, reactors, negators, interactants, or observers) can assume with respect to goal strivers' attempts to manage WFC. Building on prior work-family and social network research, we illustrate how two characteristics of the network in which an individual is embedded (i.e., centrality and density) can shape the magnitude of social network influence on WFC. Implications for theory and practice are also discussed.
