On the Endogeneity of the Mean-Variance Efficient Frontier

The endogeneity of the efficient frontier in the mean-variance model of portfolio selection is commonly obscured in the portfolio selection literature and in widely used textbooks. The authors demonstrate this endogeneity and discuss the impact of parameter changes on the mean-variance efficient frontier and on the beta coefficients of individual assets.     

Pushing Economies (and Students) Outside the Factor Price Equalization Zone

Despite overwhelming empirical evidence of the failure of factor price equalization, most teaching of international trade theory (even at the graduate level) assumes that economies are incompletely specialized and that factor price equalization holds. The behavior of trading economies in the absence of factor price equalization is not well understood, and some major textbook treatments err. The authors map regions of specialization and diversification for standard competitive economies and show how outputs, goods, and factor prices change as economies move within and across different regions of diversification and specialization. Two examples of how the analysis can enrich graduate-level trade teaching are given: the substitutability of goods trade and factor movements, and debates over the trade and inequality.     

The Development and Diffusion of Radical Technological Innovation: The Role of Bus Demonstration Projects in Commercializing Fuel Cell Technology

North American, European and Japanese governments have legislated to control Greenhouse Gas emissions and have promoted alternative technology as part of strategies to address climate change. Governments worldwide have sought to encourage adoption of alternative automotive technology by funding demonstrations and in-service trials. Among other initiatives the automotive industry has explored applications of a radical technological innovation—fuel cells—to power a range of vehicles from forklifts to buses. This paper examines the rationale and actions of various stakeholders to facilitate adoption of fuel cell technology in vehicles through a specific market segment—that of fuel cell buses (FCBs)—and explores the progress of FCB projects in North America, Europe and Japan. It examines the role of demonstration projects and highlights the complexity of the relationship between government and developers, and the multifarious and conflicting objectives of industry players that inhibit progress.     

Niche Entry as a Route to Mainstream Innovation: Learning from the Phosphoric Acid Fuel Cell in Stationary Power

The paper charts the efforts to establish a successful niche position for the phosphoric acid fuel cell (PAFC) in stationary power generation, as a precursor to wider technological system and regime change. Market entry depends on matching price/performance characteristics to a niche, and improving performance through increasing returns, the most important and immediate of which are ‘learning effects’. The paper identifies five types of learning effect: (i) migrating the technology to other niches and into the mainstream; (ii) opening the way for other technologies that may have greater scope for migration; (iii) transferring learning within the pioneering company to other technologies or products; (iv) transferring experience to others in the industry; and (v) enabling users to learn. Although PAFC may be perceived as a failure in some respects, a wider perspective suggests it has made a positive and useful contribution to learning.     

Structure,agency and causality in post-revival Austrian economics: tensions and resolutions

Abstract

This paper aims to illustrate the benefits that accrue from critical realism's sustained, explicit reflection about ontological issues. The paper pursues this aim by examining the work of radical subjectivist Austrian economists as it has developed since the post-1974 revival in the fortunes of the Austrian school, focusing in particular on their account of the generation of socio-economic order in decentralized market economies. Ambiguities and tensions can be discerned in the radical subjectivist account of the causal forces at work in the market process. It is argued that the conceptual resources required for resolving those tensions and ambiguities are to be found in critical realism. The final section of the paper draws out some of the broader implications of the suggested resolution for radical subjectivist Austrian economics.     

Jacob Viner on Adam Smith: Development and reception of a theological reading

Abstract

Jacob Viner was one of the most important interpreters of Adam Smith's work, particularly for his emphasis in a classic 1927 article on Smith's theological framework, his discussion of the relationship between the Theory of Moral Sentiments and the Wealth of Nations and dismantling of a popular view of Smith as a doctrinaire advocate of laissez-faire. What is less well known is that Viner's theological reading of Smith developed over the next 40 years through intense study of eighteenth century natural theology, and some of his views changed. This article traces the development of Viner's interpretation of Smith. It assesses the suggestion of D.D. Raphael that Smith moved away from a theological framework over time and that Viner repudiated his theological reading of Smith. I argue instead that Viner's mature work broadened and strengthened the theological reading. Much of the literature on Smith and Viner wrongly assumes that naturalistic explanation and theological frameworks are mutually exclusive. This may be the dominant twentieth century view, but it was not so in the eighteenth century, as Viner well understood.     

Cross-border Mergers and Acquisitions in China: An Industry Panel Study, 1991–2005

Employing a panel database, this article investigates empirically the behaviour, at an industry level, of cross-border mergers and acquisitions (M&As) in the People's Republic of China for the period 1991–2005. The study reports that many of the cross-border M&As over the past decades in China have been driven by broad fundamental factors, such as industry size and profitability. Moreover, technological intensity is significantly associated with the level of acquisition activity, indicating the tendency that intangible resources and intellectual capability favour more acquisition into China. It is found that deregulation, as a specific industry shock, affects acquisition activities significantly. The findings, it is concluded, have important managerial and policy implications.     

Lessons from the evolution of foreign exchange trading strategies

The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from foreign exchange (forex) technical rules in major and emerging markets, the carry trade, and US equities. The results show that a backtesting procedure to choose optimal portfolios improves upon the performance of nonadaptive rules. We also find that forex trading alone dramatically outperforms the S&P 500, with much larger Sharpe ratios over the whole sample, but there is little gain to coordinating forex and equity strategies, which explains why practitioners consider these tools separately. Forex trading returns dip significantly in the 1990s but recover by the end of the decade and have been markedly superior to an equity position since 1998. Overall, trading rule returns still exist in forex markets—with substantial stability in the types of rules—though they have migrated to emerging markets to a considerable degree.     

What is the Relationship Between REIT Governance and Earnings Management?

The empirical corporate finance literature claims that better corporate governance constrains earnings management, while others argue that the unique legal and reporting structure of REITs may reduce the need for such internal corporate governance. Using a sample of publicly traded REITs for the 2004–2008 time period, we examine the relationships amongst corporate governance, accruals earnings management, manipulation of Funds from Operations (FFO), and real earnings management. We find that corporate governance quality is unrelated to accruals earnings management and manipulation of FFO. At first glance, the findings suggest that managers need less internal oversight because of the more transparent reporting structure of REITs. However, we document that REITs engage in significant real activities manipulation for earnings management purposes. Our empirical findings further show that corporate governance characteristics, in particular board size, independence, number of board meetings and audit committee financial expertise, are essential for constraining such activities. Finally, by focusing on a subset of REITs that act in ways which previous research has identified as more susceptible to earnings management activities, we demonstrate that good corporate governance effectively reduces accruals earnings management and manipulation of FFO for these REITs. Overall, our findings indicate that, despite the unique legal and reporting structure, REITs engage in certain forms of earnings management, and that the ability for REITs to manipulate earnings is reduced when corporate governance is more effective.
