Strategy and the research process: A comment

The purpose of this paper is to expand the discussion of the ‘state-of-the-science’ in strategy research. We critically examine the role that theory plays in strategic research, and describe the principles underlying good theory. From a philosophy of science perspective, we argue that: (1) both inductive and deductive methods are valid ways of generating theory; (2) the falsificationist perspective provides an inadequate model for describing the process of theory testing; and (3) managers, researchers, public policy-makers, the popular press, and the public at large all have important roles to play in the knowledge development process.     

Value creation and destruction in cross‐border acquisitions: an empirical analysis of foreign acquisitions of U.S. firms

We conduct an investigation of the sources of gains and losses in cross‐border acquisitions in light of different motives for undertaking these transactions: synergy‐seeking, managerialism and hubris. We find that the data are consistent with the expectation that multiple sources of value creation exist in synergistic cross‐border acquisitions: asset sharing, reverse internalization of valuable intangible assets, and financial diversification. Gains accrue to bidder firm shareholders only for the least fungible of these sources of gains, i.e., reverse internalization. For value‐destroying acquisitions that are expected to be driven by managerialism, we find that the data are consistent with only one of the sources of value destruction that we examine, i.e., risk reduction. In these acquisitions, the evidence also suggests that the relative size of the target to the bidder mitigates the negative effects of risk reduction. Our results underscore the importance of considering the implications of alternative behavioral assumptions in empirical strategy content research. Copyright © 2002 John Wiley & Sons, Ltd.     

Determinants of South Asian Entrepreneurial Growth in Britain: A Multivariate Analysis

This paper aims to contribute to our understanding of the factors influencing South Asian entrepreneurial growth in Britain. It develops a multivariate model along the lines of small business economics but includes cultural and social variables. The theoretical model specified assumes that cultural factors have an augmenting effect on socio-economic factors. A distinction is also drawn between initial entrepreneurial characteristics and later expansion strategies used. The empirical model, based on the general-to-specific approach, can explain almost 60 per cent of entrepreneurial growth. The results suggest that moving away from a style of management based on immigrant culture has a positive impact on growth. This requires greater delegation of responsibilities to non-family employees. At the same time, strengthening links with the country of origin has a positive impact on growth. While the commitment to work hard at start-up is essential, human capital factors like the entrepreneur's educational attainment and employee training appear to be more crucial than financial resources in contributing to growth.

ASEAN‐5 bond market development: Where does it stand? Where is it going?

Since the late 1990s' Asian crisis, ASEAN‐5 countries have expended considerable effort in developing their bond markets. However, the size of these markets relative to GDP has hardly changed. Can we explain this? And does it mean that domestic markets have not, in fact, developed? The article argues that bond market growth has been held back by a sharp fall in business investment, which has left firms with little need for bond borrowing. Even so, markets have developed in other ways, to such an extent that substantial amounts of foreign portfolio investment have begun to flow into ASEAN‐5 bonds. These developments have important ramifications. With the investor base growing and infrastructure investment likely to rise, ASEAN‐5 bond markets could expand rapidly, holding out the prospect that the region could finally achieve ‘twin engine’ financial systems in the near future.     

Strategic redirection in large management buyouts: The evidence from post-buyout restructuring activity

This study examines the nature of post-transaction restructuring activities for 32 large U.S. corporations that underwent management buyouts between 1983–89. This study (i) provides evidence on the extent and type of divestment and acquisition activities under private ownership; (ii) documents the outcomes associated with MBOs and the longevity of the buyout organization; and (iii) investigates the claim that buyouts are primarily mechanisms for breaking up public corporations and selling the pieces to related acquirers. The balance of the evidence indicates that restoring strategic focus is an essential function of the buyout for these large firms. However, the evidence also indicates that the buyout organization does continue to operate significant parts of the prebuyout firm. By far the majority of firms continue to meet their debt obligations satisfactorily during the buyout phase. Finally, the evidence indicates that asset sales to related acquirers derive more from efficiency considerations than market power.     

Asset Maturity, Debt Covenants, and Debt Maturity Choice

The existing research on debt‐maturity under asymmetric information has focused on the impact of differential information regarding asset quality on the debt maturity decision. This research has generally indicated the optimality of short‐term debt financing as a vehicle of mitigating the adverse selection problem. In this paper, I consider the impact of information asymmetry regarding the maturity structure of cash flows on the debt maturity decision. In this context, long‐term debt is generally the form of debt financing most effective in alleviating the adverse selection problem. I also show that costs of adverse selection may induce some mismatching of debt maturity and asset maturity in the presence of significant transaction costs.     

An Endogenous Growth Model of a Financially Repressed Small Open Economy

The paper develops a monetary endogenous growth model of a financially repressed small open economy, characterized by curb markets, capital mobility, transaction costs in domestic and foreign capital markets, and a flexible exchange rate system, to analyze the impact of financial liberalization – interest rate deregulation and lower multiple reserve requirements – on growth and inflation. When the model is calibrated to match world figures, we find that interest rate deregulation enhances growth and reduces inflation in steady-state. For relatively smaller transaction costs in the curb market, the above result is, however, reversed. Under such circumstances, lowering the transaction costs in the foreign capital market tends to restore the growth-enhancing (inflation-reducing) capabilities of interest rate deregulation. Lower reserve requirements, though, always ensures lower (higher) steady-state inflation (growth).
