Risk Aversion and the Bid–Ask Spread

This paper studies the properties of bid and ask prices posted by a monopolistic market maker, without parametric assumptions about the utility function of the market maker or about the probability distribution of the return of the risky asset. We first prove that the two prices can be higher or lower than the expected value of the asset, and that the spread is decreasing in the initial wealth when the market maker exhibits decreasing absolute risk aversion. We conclude by some examples illustrating the fact that almost all shapes can be obtained for the bid–ask spread (as a function of the inventory) depending on the probability distribution of the payment of the risky asset.     

The performance of hedge funds and mutual funds in emerging markets

Use of short selling and derivatives is limited in most emerging markets because such instruments are not as readily available as they are in developed capital markets. These limitations raise questions about the value added provided by hedge funds, especially compared to traditional mutual funds active in these markets. We use five existing performance measurement models plus a new asset-style factor model to identify the return sources and the alpha generated by both types of funds. We analyze subperiods, different market environments, and structural breaks. Our results indicate that some hedge funds generate significant positive alpha, whereas most mutual funds do not outperform traditional benchmarks. We find that hedge funds are more active in shifting their asset allocation. The higher degree of freedom that hedge funds enjoy in their investment style might thus be one explanation for the differences in performance.     

Earnings Forecasts and the Information Contained in Spinoff Announcements

This study examines spinoff announcements in conjunction with financial analysts’ forecasts of earnings. The analysis shows that spinoff announcement abnormal returns are significantly related to the firm's information environment as proxieci by financial analysts’ earnings prediction errors. The findings also indicate that analysts significantly increase their short-term earnings forecasts in response to spinoffs, but do not significantly revise their long-term earnings forecasts. However, the earnings revisions are not significantly different across prediction error groups, which confirms that spinoff-related abnormal returns cannot be attributed solely to expected performance gains.     

The Effects of Environmental Turbulence on New Product Development Strategy Planning

Managers need guidance on how to cope with turbulent environments in order to improve corporate performance. Research on environmental turbulence has suggested that firms adopt a less centralized, more organic structure in dynamic, uncertain environments. Little work has been done specifically, however, on how environmental turbulence affects strategy planning for new product development (NPD). In this article, we specify a baseline model with firm innovativeness, market orientation and top management risk taking as antecedents to NPD speed and corporate strategic planning; these in turn are modeled as antecedents to NPD program (not project) performance. Two conceptualizations of the role of environmental turbulence are examined: (1) that market turbulence and technological turbulence are additional direct antecedents to NPD program performance; and (2) that the baseline model is moderated by turbulence (that is, that the strengths of the paths differ depending on levels of turbulence). A cross-sectional survey methodology including four diverse industries [automotive, electronics, publishing, and manufacturing/research and development (R&D) laboratories] was used to test the hypotheses. The latter conceptualization is supported. In particular, the paths from innovativeness to strategic planning and from risk taking to NPD speed are significantly greater in highly turbulent environments. A set of managerial recommendations and implications are provided. First, managers must recognize the possible improvements in new product performance by actively including NPD personnel in corporate strategic planning and also by involving corporate planners in NPD activities. Second, managers also should recognize that turbulent environments heighten the need to make risky investments, and sometimes, risky decisions; risk-taking decisions ought to be encouraged in such environments.     

Alfred E. Kahn, 1917–2010

Our introduction to this compendium reviews Alfred Kahn’s academic and policy interests, his activities as a regulator and advisor to governments and companies, and the interactions between these aspects of his life as an economist. Although best known for his research on the economics of regulation and his application of microeconomic principles in his role as a regulator and advisor, Kahn’s academic research portfolio was much more diverse. He wrote about patent policy, economic development, antitrust policy, and other topics, in addition to his work on regulation and deregulation. Even before becoming a regulator he was actively involved in applying economic principles to regulatory problems as an advisor and consultant. In all of his work Kahn recognized that markets were imperfect, but that policies aimed at improving market performance often made things worse. His experience as a regulator and consultant strengthened his recognition that the costs of imperfect regulation had to be carefully balanced against the costs of imperfect markets. One had to search for the best that could be done in an imperfect world. Kahn was particularly fascinated by the challenges of designing and implementing policies to govern the transition from regulated monopoly or oligopoly to an industry that would ultimately rely primarily on competitive markets to govern firm behavior and performance. Fred Kahn was an extraordinary man who is missed greatly by his many friends and colleagues representing a wide range of political orientations and approaches to economic and public policy analysis.     

The price of fear: Estimating the financial cost of bullying and harassment to the NHS in England

Using a spectrum of measures, this paper estimates some of the financial costs of bullying and harassment to the NHS in England. By means of specific impacts resulting from bullying and harassment to staff health, sickness absence costs to the employer, employee turnover, diminished productivity, sickness presenteeism, compensation, litigation and industrial relations costs, we conservatively estimate bullying and harassment to cost the taxpayer £2.281 billion per annum.     

Effects of overseas production on home country exports: Evidence based on Swedish multinationals

Effects of Overseas Production on Home Country Exports: Evidence Based on Swedish Multinationals. —Using unique data on Swedish multinationals 1974–1990, the impacts of overseas production on parent exports are analyzed. Two methodological applications are introduced: (i) In order to avoid sample selection bias, the model includes also countries to which the firm exports, but has not established any affiliates; (ii) the effect of affiliate exports to “third countries” is incorporated. The results suggest that increased foreign production both replaces exports of finished goods and attracts intermediate goods from the parent. In contrast to previous studies, the net effect is negative, albeit significant only in the case of affiliate exports in the EC.     

Information asymmetries and technological innovation in large engineering construction projects

Research on technological innovation shows that information asymmetries between suppliers and buyers constitute a major barrier to the successful introduction of new products. Most of this research, however, puts the burden of overcoming these asymmetries on producers of new products. In the case of large engineering construction projects innovation is often the result of joint problem solving by owners, prime contractors, consultants, and equipment suppliers. In this paper we examine the relationship between innovativeness of large engineering construction projects and internal owner capabilities, degree of control over project, and dependence on external organizations, We use data on power plant construction projects to test hypotheses derived from agency and organization theories of innovation. Our results indicate that organization theories of innovation are on the whole better predictors of the impact on innovativeness of owner's capabilities and relationship to external organizations.
