Industry Evolution, Corporate Scope, Technological Innovation, Entrepreneurship, Chinese economy
My research examines the role of firm capabilities in influencing the dynamics of corporate scope and the evolution of industries. My work can be organized into two streams, with the first stream related to firms’ strategies for reconfiguring their business portfolios in dynamic environments, and the second related to industry evolution driven by entry, exit, and incumbent adaptation. These two streams are linked by a common concern with how competitive advantage is created and destroyed when industry landscapes are reshaped by economic, technological, and institutional factors.
Organizational Constraints to Adaptation: Intra-Firm Asymmetry in the Locus of Coordination. (with Vikas Aggarwal). Forthcoming. Organization Science.
Abstract: We assemble a panel dataset of firms in the U.S. defense industry between 1996 and 2006 to examine the drivers of heterogeneous incumbent firm adaptation following the industry-wide demand shock of September 11, 2001. This shock entailed not only an increase in aggregate demand, but more importantly a shift in the relative attractiveness of individual product areas, resulting in the need for firms to reshuffle their product portfolios in response to changing demand conditions. The exogenous nature of the shock allows us to empirically identify the effect of pre-shock interdependence structures on post-shock adaptation outcomes. We find that the locus of coordination inside a firm can explain differential post-shock adaptation performance: because interdependencies spanning organizational boundaries are more difficult to manage than those contained within such boundaries, coordination across product areas creates greater adaptation challenges as compared to coordination within product areas. We further investigate the moderating effects of product complementarity and organizational grouping, finding results consistent with our hypothesized mechanisms. As one of the first studies to empirically link a firm’s locus of coordination with its adaptation performance, this study contributes to our understanding of the role of interdependence and organization design in dynamic environments.
Complementary assets as pipes and prisms: Innovation incentives and trajectory choices. (with Zhixi Wan and Daniel Levinthal). 2014. Strategic Management Journal. 35(9): 1257–1278 (lead article).
Abstract: Under-investment in radical innovation is often pointed to as the basis for incumbent failure in the face of radical change. However, it is also commonly observed that incumbents make substantial investments in radical innovations. To address the paradox of incumbent failure despite heavy investments, we develop an analytical model that considers firm heterogeneity with respect to both technical trajectories and complementary capabilities. In this model, complementary assets play a dual role in incumbents’ investment behavior toward radical technological change: complementary assets are not only resources [pipes] that can buffer firms from technology change, but are also prisms through which they view those changes, in terms of both the magnitude of resources that should be invested and the trajectory to which these resources should be directed.
Institutional barriers and industry dynamics. (with Sea-Jin Chang). 2014. Strategic Management Journal, 35(8): 1103–1123 (lead article).
Abstract: This study demonstrates new entrants exhibit higher productivity but also higher exit hazard than incumbents in post-liberalization China. We argue this seemingly paradoxical relationship is attributable to institutional barriers, defined as the hindrance in the institutional environment that prevents market selection forces to function. New entrants require higher productivity to compensate for those institutional barriers, which in turn implies a higher exit hazard after controlling for productivity. Our empirical findings support this argument and further show that the differences in productivity and exit hazard between new entrants and incumbents become smaller where and when institutional barriers recede. By integrating economic and institutional perspectives, we highlight the importance of institutional factors in shaping industry evolution.

Opportunity costs, industry dynamics, and corporate diversification: Evidence from the cardiovascular medical device industry, 1976-2004. 2013. Strategic Management Journal, 34(11): 1265–1287 (lead article).
Abstract: This paper examines how demand conditions across alternative markets impact diversification decisions and firm performance by influencing the opportunity costs of deploying non-scale free capabilities. Using data within the cardiovascular medical device industry, this study shows that: (1) firms with a larger stock of pre-entry innovation experience are more likely to diversify; (2) firms in a current market with greater relative demand maturity are more likely to diversify; (3) diversification is associated with a performance decrease in the current market; and (4) diversification is associated with a performance increase at the corporate level. These findings shed new light on the self-selection process of corporate scope, the conceptualization of firm capabilities, and the connection between industry dynamics and resource deployment.
Opportunity costs and non-scale free capabilities: Profit maximization, corporate scope, and profit margins. (with Daniel Levinthal). 2010. Strategic Management Journal, 31(7): 780-801.
Abstract: The resource-based view on firm diversification, subsequent to Penrose (1959), has focused primarily on the fungibility of resources across domains. We make a clear analytical distinction between scale free capabilities and those that are subject to opportunity costs and must be allocated to one use or another, thereby shifting the discourse back to Penrose’s (1959) original argument regarding the stock of organizational capabilities. The existence of resources and capabilities that must be allocated across alternative uses implies that profit-maximizing diversification decisions should be based upon the opportunity cost of their use in one domain or another. This opportunity cost logic provides a rational explanation for the divergence between total profits and profit margins. Firms make profit-maximizing decisions to increase total profit via diversification when the industries in which they are currently competing become relatively mature. Due to the spreading of these capabilities across more segments, we may observe that firms’ profit-maximizing diversification actions lead to total profit growth but lower average returns. The model provides an alternative explanation for empirical observations regarding the diversification discount. The self-selection effect noted in recent work in corporate finance may not be indicative of inferior capabilities of diversifying firms but of the limited opportunity contexts in which these firms are operating.
Spillover asymmetry and why it matters. (with Anne-Marie Knott and Hart Posen). 2009. Management Science, 55(3): 373-388.
Abstract: Although spillovers are a crucial factor in determining the optimal environment for innovation, there is no consensus regarding their impact on firm behavior. One reason for this may be that models differ in their assumptions for the functional form of the spillover pool. In industrial organization and economic geography, for example, the predominant convention is that all innovation within an industry/region contributes to a spillover pool that has a common value for all firms. An alternative convention prevalent in endogenous growth and evolutionary economics is that spillovers have directionality—the size of the relevant pool differs across firms. Knowing the correct functional form may facilitate theoretical consensus, either analytically (by modifying models’ assumptions) or empirically (by supporting a critical test of competing theories). We characterize and test the functional form of spillover pools for efficiency-enhancing innovation across 50 markets in the banking industry. Our results in that setting are consistent with expectations for asymmetric spillovers but inconsistent with expectations for pooled spillovers.
Entrepreneurial risk and market entry. (with Anne-Marie Knott). 2006. Management Science, 52(9): 1315-1330.
Winner of the 2005 Annual Best Student Paper Award from the Office of Advocacy of the US Small Business Administration.
Abstract: This paper attempts to reconcile the risk-bearing characterization of entrepreneurs with the stylized fact that entrepreneurs exhibit conventional risk-aversion profiles. We propose that the disparity arises from confounding two distinct dimensions of uncertainty: demand uncertainty and ability uncertainty. We further propose that entrepreneurs will be risk averse with respect to demand uncertainty, yet “apparent risk seeking” (or overconfident) with respect to ability uncertainty. To examine this view, we construct a reduced-form model of the entrepreneur’s entry decision, which we aggregate to the market level, then test empirically. We find that entrepreneurs in aggregate behave as we predict. Accordingly, risk-averse entrepreneurs are willing to bear market risk when the degree of ability uncertainty is comparable to the degree of demand uncertainty. Potential market failures exist in instances where there is a high demand uncertainty but low performance dispersion (insufficient entry), or low demand uncertainty but high performance dispersion (excess entry).
Lessons from Alibaba.com: Government’s role in electronic contracting. (with Qin Hu and Clement Wang). 2003. INFO – The Journal of Policy, Regulation and Strategy for Telecommunications, Information and Media, 6(5): 298-307.
Abstract: Although electronic commerce (e-commerce) can be a source of competitive advantage, will e-commerce businesses in countries like China flourish when governments still take a “wait-and-see attitude” as to prompting, protecting, and regulating e-commerce? The paper employs transaction cost economics in analyzing the role of government in regulating electronic contracting. Due to the transaction costs arising from e-commerce, explicit contracts between parties are usually incomplete. The paper argues that these contracts should always be backed by implicit contracts, which are determined by default rules in various governments. Therefore, it behoves governments urgently to fill gaps in incomplete contracts in e-commerce in order to foster a predictable legal environment for e-businesses, minimize legal risks and transaction costs, and maximize economic and social benefits. The authors believe that governments must also act in concert with one another at the international level to create a favorable and consistent commercial environment.

"Schumpeterian Competition, Inter-Organizational Learning, and the Dynamics of Spillover Pools" (with Gianluigi Giustiziero). Invited for 2nd review at Organization Science.
Abstract: This paper examines how knowledge stocks affect inter-organizational learning in Schumpeterian environments. We argue that the dual nature of knowledge stocks – learning and competition – leads to the dynamics of spillover pools, a construct often assumed to be exogenous in the literature. While knowledge stocks may increase incumbents’ learning ability, they also create competitive concerns for entrants, who constitute an important source of new ideas for the industry spillover pool. In response to competitive threats, entrants may choose different technological positions, thus reducing their technological proximity to incumbents and consequently diminishing the spillover pool accessible to incumbents. Overall, we enrich the inter-organizational learning literature by showing that high investment levels in knowledge stocks, which may facilitate learning by increasing absorptive capacity in a static environment, may have the opposite effect in a Schumpeterian setting. Our paper further contributes to the recent development of the duality tenet of the resource-based view of the firm by identifying competitive concerns as a strategic source of within-market firm heterogeneity. We find support for our theoretical arguments in the cardiovascular medical device industry.
“A capabilities-based Perspective on Target Selection in Acquisitions” (with Aseem Kaul). Invited for 2nd review at Strategic Management Journal.
Abstract: This study examines the choice of acquisition targets by horizontal acquirers. Taking a capability-based perspective, we argue that acquirers prefer targets with different levels of capability in similar contexts or markets. Moreover, acquirers will seek to balance these dimensions, seeking targets with inferior capabilities in existing markets, but superior capabilities in new but related markets, especially when their own integration capabilities are weak. Results from an analysis of horizontal acquisitions in the Chinese brewing industry from 1998 to 2007 provide support for our theory. The paper contributes to the acquisition literature by providing a capability-based perspective on the factors that drive target selection by acquirers, highlighting the distinction between capability transfer and capability combination as sources of value in acquisitions, as well as the role of acquirer integration capabilities.
“When Suppliers Climb the Value Chain: A Theory of Value Distribution in Vertical Relationships” (with Zhixi Wan)
Abstract: While offshore outsourcing has become an important strategy to lower production costs among western firms, it gives rise to a phenomenon of value chain climbing – suppliers in emerging markets can develop capabilities by supplying, with aspirations to compete with the buyers in the product market. We build an analytical model to study the impact of value chain climbing on value distribution in vertical relationships. The analysis identifies a set of dominant relationships, and shows how the buyer’s choice among these relationships depends on firms’ relative competitiveness in the product market and the supplier’s speed of capability development. The results provide new insights into our understanding of value distribution in vertical relationships across different contexts. We further extend the model to a dynamic setting, showing how vertical relationships and, consequently, value distribution evolve over time. By endogenizing the supplier’s entry into the product market, our study enriches the literatures on vertical relationships, market entry, and the management of global value chains.
