Endogenous product substitutability strategy under duopoly

This article develops endogenous product substitutability theory. With game theory approach, the effects of endogenous product substitutability are characterized. First, equilibrium under endogenous product substitutability is achieved. Second, product substitutability strategy promotes price, total outputs, and social welfare. Outputs under high‐efficiency firm's product substitutability are compared with those under low‐efficiency firm's product substitutability. Third, compared with the other cases, joint product substitutability improves price difference. Finally, the outputs of all firms under endogenous product substitutability are shown to be lower than the social optimality level. The policy implication is to encourage firms investing product substitutability.     

Business model innovation in cultural and creative industries: Insights from three leading mobile gaming firms

This paper contains an exploratory analysis of the business model innovations (BMIs) that firms in cultural and creative industries (CCIs) undertake along their life-cycle. Despite the role that creative and cultural and creative firms (CCFs) have in the economic development of industrialised countries, they tend to remain small and often fail due to industry-specific constraints and tensions, such as the lack of managerial capabilities and complexity in nurturing value chain relationships. However, there has been relatively limited scholarly interest into the specific conditions and processes that enabled CCFs to overcome these liabilities, and in particular into the identification of the business models they have adopted along their life-cycle. In this paper, this issue is analysed by using the concept of BMI, which sheds light on how the reconfiguration of the activity system through which a CCF creates, delivers and captures value enables the exploitation of entrepreneurial opportunities over time. This paper builds on an in-depth historical study of three leading firms operating in the mobile gaming industry, namely Rovio, Zynga and King Digital Entertainment. Three main results emerge from this study. First, in the ramp-up phase of their life-cycle, CCFs organize their resource architecture to build a strong and recognized reputation. Second, in the development phase, BMI is used to leverage new distribution paradigms. Finally, in the maturity phase, firms dedicate resources to innovate their product portfolios by providing platforms that support the development and testing of new creative ideas and solutions. Findings and implications are then discussed.     

Vertical Integration and Firm Productivity

This paper uses three cross‐industry datasets from China and other developing countries to study the effect of vertical integration on firm productivity. Our findings suggest that vertical integration has a negative impact on productivity, in contrast to recent studies based on U.S. firms. We argue that in settings with poor corporate governance, vertical integration reduces firm productivity because it enables inefficient rent‐seeking by insiders.     

Closing the innovative loop: moving from the laboratory to the shop floor in biotechnology manufacturing

Innovation is a hallmark of successful technology-intensive start-up companies. This paper considers manufacturing as a knowledge-generating activity integral to product innovation in entrepreneurial biotechnology firms. The model of the virtual corporation has been advocated as a means to focus on the resources of start-up companies; yet regional specialization in technical applications and product categories suggests that manufacturing may be a knowledge-generating activity that can provide a potential source of regional advantage. This paper considers the manufacturing strategies that bio-entrepreneurs would like to pursue and explores barriers to forward integration. While capital constraints may force firms to licence and subcontract manufacturing, it was found that entrepreneurs believe that it is important to undertake manufacturing and, when they are financially able, they invest in manufacturing facilities. The authors conclude by providing a framework for considering when it might be most appropriate for biotechnology firms to invest in manufacturing.     

Price and quality competition with quality positions

In this study, we investigate price and quality decisions in a duopoly in the presence of firms’ quality positions , which are determined by the quality levels of their existing core products. Into a standard model of vertical differentiation, we incorporate a “repositioning cost” that is proportional to the quality differences between firms’ current and new products. By varying the levels of quality positions, we analyze the impact of this cost on the equilibrium outcomes. Our results show that the presence of repositioning costs restricts firms’ abilities to improve profitability and differentiate themselves vertically. As a result, a high‐positioned firm does not necessarily have a competitive advantage over a low‐positioned firm, even if the former offers a superior new product in equilibrium. In addition, if a low‐positioned firm is significantly cost‐efficient compared with its rival with regard to repositioning, then that firm can earn higher profits than those of a high‐positioned firm by strategically offering its low‐end product. These results contrast sharply with those based on the standard vertical differentiation model.     

Product Differentiation and Upstream-Downstream Relations

This paper examines the relationship between a differentiated downstream market and a specialized upstream market. We analyze three different types of vertical relation between the upstream and downstream sectors when the upstream market supplies specialized and complementary inputs to a downstream product-differentiated market. The first is the benchmark case of decentralized markets, the second is a network of alliances among upstream suppliers, and the third is partial vertical integration. We identify the perfect equilibrium for a symmetric model in each case and show that there is no simple relationship between the degree of connection between upstream and downstream firms and profitability. The key factor affecting prices and the relative profitability of the different market organizations is the degree of product differentiation among the downstream firms, because it affects the intensity of competition among upstream suppliers. We show that vertical foreclosure is not an equilibrium strategy.     

Vertical Foreclosure, Technological Choice, and Entry on the Intermediate Market

This paper analyzes the profitability of vertical integration for an upstream monopoly facing a potential competitor. We show that it depends on the technology used by the firm when it integrates. We distinguish two types of technologies: standard technologies, used by nonintegrated firms, and nonstandard technologies, reserved for integrated firms and implying the complete foreclosure of nonintegrated firms. Vertical integration with the adoption of a nonstandard technology dominates vertical integration with the adoption of a standard technology and is profitable, as long as the degree of competition in the downstream industry is sufficiently low.     

An analysis of environmental corporate social responsibility

This article investigates corporate social responsibility (CSR) practices while taking into account their product substitutability and environmental responsibility. CSR firms, integrating environmental and social concerns into its business operations, are introduced. The effects of the firms' social concerns, environmental responsibility, and product substitutability are all captured. First, firms' social concerns improve both outputs and CSR firms' objective function value, while reducing the profit maximization firm's profits. Second, environmental responsibility has the contrary effects. Both the outputs and the objective function values of both firms decrease with their product substitutability. Finally, social concern effects on CSR firms' performance are uncertain.

A transaction cost approach to a paradox in international marketing

Why do firms that make specific downstream investments as they start international operations, sometimes turn to more market-like arrangements as they gain international experience and their international sales increase? This paradox in international marketing is the key question to be addressed in this article. We use the concept of dynamic or temporary governance costs to examine the paradox. The pattern of internationalization in the Norwegian farmed salmon industry provides an example whereby Norwegian exporters established their own sales offices in several international markets in the early stages of internationalization, but subsequently disintegrated vertically and came to rely on more market-like arrangements. An analysis of the internationalization of this industry suggests that, over time, the market provided better capabilities than vertical integration. This reduced the transaction costs, thus making vertical disintegration an efficient strategy.

Venture capitalist monitoring: Evidence from governance structures

We examine the impact of venture capitalist (VC) involvement, quality and exit on corporate governance structures at the time of and subsequent to an initial public offering (IPO). Venture capital backed firms utilize governance structures with greater levels of monitoring at the time of an IPO compared to non-backed firms, but this difference begins to dissipate over time. While short-lived, IPOs backed by high quality VCs have greater overall monitoring levels than those IPOs backed by low quality VCs. IPOs backed by high quality VCs use significantly more equity-based compensation than their low quality counterparts. Finally, the exit of a VC materially alters the governance structure of firms. Measures of governance decline following the departure of a venture capital firm. Overall, the presence of a venture capitalist affects governance structures of firms both at the IPO and through the early years as public firms.     

Price and Quantity Competition in a Differentiated Duopoly with Upstream Suppliers

This paper analyzes the noncooperative game on the choice of strategic variable to set in duopoly in the presence of an upstream market for the input. For the case of labor input, the analysis shows that if the wage is the result of decentralized firm-union bargain, a duopoly producing substitutes may choose to compete either in the quantity space or in the price space, depending upon the distribution of bargaining power in the wage negotiation and the union's relative preference over the wage. For the case of input suppliers as profit-maximizing firms, the paper shows that a vertically differentiated duopoly may prefer to compete either in the quantity space or in a mixed strategy setting where the high-quality firm plays price and the low-quality firm plays quantity, depending upon the extent of substitutability, the degree of vertical product differentiation and the distribution of bargaining power in the input price negotiation.     

Convergence to symmetry in dynamic strategic models of R&D: The undiscounted case

Will R&D increase or decrease the asymmetry between firms over time? We examine this issue in the context of a dynamic, alternate-move duopoly model of non-cooperative R&D. The asymmetry we consider is with respect to the initial stocks of technological knowledge which provides one firm a greater potential for current and future profits in the product market. Utilizing a value loss process constructed from the Optimality Equation of dynamic programming, we show that for the undiscounted case the asymmetry between the firms disappears over time. We obtain this convergence-to-symmetry result by imparting a temporal character to R&D through the notion that R&D investment cannot be changed instantaneously, by allowing research externalities, complementarity or substitutability between own and appropriated R&D, and either increasing, decreasing or constant returns to scale in the production of technical knowledge from own and rival R&D.     

On the relationship between product substitutability and tacit collusion

This paper examines the effect of increased product substitutability on quantity‐setting firms’ ability to sustain tacit collusion in a market. It uses a general demand function and the trigger strategy of Friedman (Friedman JW. 1971. A non‐cooperative equilibrium for supergames. Review of Economic Studies 38: 1–12) to show that while increased product substitutability hinders sustainability of tacit collusion in the case of linear and concave demand functions, it may either hinder or facilitate firms’ ability to sustain tacit collusion in the case of convex demand functions. Thus, this paper adds to the growing view that one must use a case‐by‐case analysis in judging whether firms in more homogenous product markets find it easier or harder to tacitly collude.

Privatisation and vertical integration under a mixed duopoly

This paper analyses the privatisation of public firms when private firms may be vertically integrated with their suppliers. We consider a mixed duopoly with a vertically integrated public firm. The private firm bargains the price of the input with its supplier if they are not vertically integrated. We find that for a given bargaining power of the private firm, it vertically integrates with its supplier if goods are weak substitutes. We also find that there is less vertical integration in the mixed duopoly than in the private duopoly. Finally, in general, the public firm is privatised when goods are close substitutes and the bargaining power of the private firm is low enough.     

Vertical integration and first-mover advantages in environmental taxes

This paper analyzes whether vertical integration between firms and suppliers encourages governments to behave as leaders in environmental policies. To study this issue, we consider transboundary pollution and two countries, with one firm in each country. We find that whether governments prefer to be leaders or followers in environmental taxes depends on two factors: whether firms are vertically integrated or not and the degree to which environmental pollution spills over to trading partners. When this overspill takes an intermediate value, taxes are set sequentially under vertical integration, but they are set simultaneously without it.     

The Choice of Prices versus Quantities under Uncertainty

This paper analyzes a duopoly model with stochastic demand in which firms first commit to a strategy variable and compete afterwards. We find that in equilibrium the relative magnitude of demand uncertainty and the degree of substitutability determines firms' variable choice. Firms set prices if uncertainty is high compared to the degree of substitutability and quantities if the reverse holds true. The reason is that demand uncertainty and the degree of substitutability have countervailing effects on variable choice: Prices adapt better to uncertainty while quantities induce softer competition. If no effect dominates, firms choose different strategy variables in equilibrium.     

A Knowledge Accessing Theory of Strategic Alliances

ABSTRACT The emerging knowledge‐based view of the firm offers new insight into the causes and management of interfirm alliances. However, the development of an effective knowledge‐based theory of alliance formation has been inhibited by a simplistic view of alliances as vehicles for organizational learning in which strategic alliances have presumed to be motivated by firms’ desire to acquire knowledge from one another. We argue that the primary advantage of alliances over both firms and markets is in accessing rather than acquiring knowledge. Building upon the distinction between the knowledge generation (‘exploration’) and knowledge application (‘exploitation’), we show that alliances contribute to the efficiency in the application of knowledge; first, by improving the efficiency with which knowledge is integrated into the production of complex goods and services, and second, by increasing the efficiency with which knowledge is utilized. These static efficiency advantages of alliances are enhanced where there is uncertainty over future knowledge requirements and where new products offer early‐mover advantages. Compared with alternative learning‐based approaches to alliance formation, our proposed knowledge‐accessing theory of alliances offers the advantages of greater theoretical rigour and consistency with general trends in alliance activity and corporate strategy.     

Vertical integration and innovative performance: The effects of external knowledge sourcing modes

We set out in this study to analyze the impact of vertical integration on the innovative performance of a firm and to explore the interaction between vertical integration and different modes of external knowledge sourcing. Our empirical results reveal an initial increase in the effect of vertical integration on innovative performance up to a certain level of integration, although this is subsequently followed by a decline; that is, the relationship is characterized by an inverted U-shape. The results further reveal that external knowledge sourcing is positively related to the innovative performance of a firm, albeit with a negative interaction with the level of vertical integration. In other words, firms with higher levels of vertical integration may be faced with barriers to the acquisition of external knowledge. Our findings suggest that firms should be cautious in their pursuit of a strategy of vertical integration, given the non-monotonic impact on innovative performance, whilst an increase in the level of vertical integration is also likely to diminish the effectiveness of the external knowledge sourcing.
