Patterns of strategic alliances between rival firms

This article describes the results of a research project which examined 171 alliances set up by competing firms in an international context. It presents an empirically-based taxonomy of such alliances constructed on the basis of a set of variables chosen for their demonstrated or assumed influence on the evolution and outcomes of strategic partnerships. Three contrasted types of alliances are identified: quasi-concentration alliances, market penetration alliances and shared supply alliances. They differ according to two fundamental dimensions: their symmetrical or dissymmetrical nature and the way in which they alter competition. Legal structure, often emphasized in previous research on the subject, does not emerge as a strongly discriminating factor. Hypotheses on the likely evolution and outcomes of each type of alliance are derived from the taxonomy.We are grateful to Barbara Gray, Stuart Hart, Aneel Karnani, Will Mitchell, Michel Tenenhaus, and to two anonymous reviewers for their very valuable and helpful comments on earlier drafts of this article.

Estimating daily volatility in financial markets utilizing intraday data

This study proposes a new approach to the estimation of daily realised volatility in financial markets from intraday data. Initially, an examination of intraday returns on S&P 500 Index Futures reveals that returns can be characterised by heteroscedasticity and time-varying autocorrelation. After reviewing a number of daily realised volatility estimators cited in the literature, it is concluded that these estimators are based upon a number of restrictive assumptions in regard to the data generating process for intraday returns. We use a weak set of assumptions about the data generating process for intraday returns, including transaction returns, given in den Haan and Levin [den Haan, W.J., Levin, A., 1996. Inferences from parametric and non-parametric covariance matrix estimation procedures, Working paper, NBER, 195.], which allows for heteroscedasticity and time-varying autocorrelation in intraday returns. These assumptions allow the VARHAC estimator to be employed in the estimation of daily realised volatility. An empirical analysis of the VARHAC daily volatility estimator employing intraday transaction returns concludes that this estimator performs well in comparison to other estimators cited in the literature.     

Dynamic monopoly pricing with network externalities

In this paper, we study the optimal dynamic monopoly pricing for a good which exhibits positive network externalities. When network externalities are of sufficient magnitude, we show that, contrary to the Coase theorem, (1) there is no time inconsistency problem; (2) subgame perfect equilibrium prices increase as time passes. From this point of view, positive network externalities allow the monopoly to commit itself credibly to increasing future prices.Ce papier étudie la tarification optimale intertemporelle d'un monopole qui vend un bien exhibant des externalités positives de réseau. Lorsque ces externalités sont suffisamment importantes, nous montrons que, contrairement au théorème de Coase, (1) il n'y a pas de problème d'incohérence temporelle, (2) les prix d'équilibre parfait croissent avec le temps. De ce point de vue, les externalités positives de réseau permettent au monopole de s'engager crédiblement sur une politique de prix futurs à la hausse.     

Trade costs, firms and productivity

This paper examines the response of U.S. manufacturing industries and plants to changes in trade costs using a unique new dataset on industry-level tariff and transportation rates. Our results lend support to recent heterogeneous-firm models of international trade that predict a reallocation of economic activity towards high-productivity firms as trade costs fall. We find that industries experiencing relatively large declines in trade costs exhibit relatively strong productivity growth. We also find that low-productivity plants in industries with falling trade costs are more likely to die; that relatively high-productivity non-exporters are more likely to start exporting in response to falling trade costs; and that existing exporters increase their shipments abroad as trade costs fall. Finally, we provide evidence of productivity growth within firms in response to decreases in industry-level trade costs.     

An empirical test of the Balassa-Samuelson hypothesis: Evidence from eight middle-income countries in Africa

The paper tests the validity of the Balassa-Samuelson hypothesis (BSH) using the within-effects and the dynamic panel generalised methods of moment (GMM) techniques for a panel of eight middle-income African countries over the period 1960–2009. We selected these countries because they exhibited a mixture of relative productivity growth and real exchange rate misalignment that fits the characterization of the BSH well. The results strongly support the BSH for this group of countries. The results are valid even after we controlled for potentially omitted variables and endogeneity. The implication is that as these countries become more productive, their currencies appreciate in real terms.     

Entry and capital structure mimicking in concentrated markets: The role of incumbents’ financial disclosures

We examine whether the public availability of product market incumbents' financial disclosures leads to greater capital structure mimicking of incumbents by entrants. Exploiting a change in disclosure enforcement for German private firms in the mid-2000s, we find entrant-incumbent mimicking rises substantially in concentrated markets once incumbents' financial statements are publicly available. Additional tests exploring potential mechanisms are more consistent with interfirm learning underlying the effect than alternative channels. Our findings shed light on the effects of competitor financial statement disclosure on private firms’ initial financing decisions and highlight how capital structure dependencies among peer firms arise.

Competitive and Comparative Advantage: Towards a Unified Theory of International Trade

The field of international business/economics is largely dualistic in nature. On one hand is the economics literature which has, for two centuries, focused on the notion of comparative advantage (technology, factor proportions) while on the other is the business literature which has recently developed the concept of competitive advantage. This paper presents a reconciliation of the two based on global value chain/supply chain analysis and the concept of vertical comparative advantage. It is shown that the theory of competitive advantage's epistemological comparative advantage lies with its ‘how to’ approach to developing an advantage, while the theory of comparative advantage's epistemological comparative advantage lies with its account of ‘what is’ and that both are complementary. However, it is also argued that the failure to recognize this complementarity as well as the shortcomings of each have prevented and continue to prevent the emergence of an integrated, empirically-consistent theory of international trade – in short, prevented us from taking advantage of the gains from epistemological trade.
