Using technology to improve the management of development impacts on biodiversity

The mitigation hierarchy (MH) is a prominent tool to help businesses achieve no net loss or net gain outcomes for biodiversity. Technological innovations offer benefits for business biodiversity management, yet the range and continued evolution of technologies creates a complex landscape that can be difficult to navigate. Using literature review, online surveys, and semi-structured interviews, we assess technologies that can improve application of the MH. We identify six categories (mobile survey, fixed survey, remote sensing, blockchain, data analysis, and enabling technologies) with high feasibility and/or relevance to (i) aid direct implementation of mitigation measures and (ii) enhance biodiversity surveys and monitoring, which feed into the design of interventions including avoidance and minimization measures. At the interface between development and biodiversity impacts, opportunities lie in businesses investing in technologies, capitalizing on synergies between technology groups, collaborating with conservation organizations to enhance institutional capacity, and developing practical solutions suited for widespread use.     

Institutional framing and perceptions of fairness

This paper's goal is to construct a positive theory of economic fairness. Using the theoretical schema developed by Hurwicz and others, the paper makes precise the notions of an “institution,” “fairness fraiming,” and “institutional framing.” Four fairness propositions yield an important corollary: the economic environment, the operative institution and history give meaning to the often used FORMAL PRINCIPLE OF DISTRIBUTIVE JUSTICE (“equals should be treated equally, and unequals unequellay, in proportion to relevant similarities and differences”). We support these four propositions and corollary by an analysis of laboratory, survey, and anecdotal evidence. Finally we describe a number of areas for future research.

Efficiency and Technological Change in the U.S. Brewing Industry

This study demonstrates that the measurement of technological change and economic efficiency are tightly linked. Efficiency measures may depend on carefully controlling for technological change, while tests of technological change may be sensitive to empirical model specifications. Moreover, the study underlines Solow's (1994) and Romer's (1994) admonition that econometricians should pay attention to industry and institutional evidence in building models of technological change. The empirical results presented here suggest that there has been substantial technological change in the U.S. brewing industry from 1950 to 1992. This occurred in the form of a dramatic shift in technology beginning with the introduction of super breweries in about 1972. There has also been a substantial increase in scale economies, which undoubtedly caused many inefficiently small firms to exit the industry during the 1960s and 1970s. Further results suggest that a more complete specification of technological change and the stochastic nature of the frontier production function leads to higher and more tenable estimates of efficiency.     

Examining the relative influence of upper echelons ties on IPO underpricing

Integrating signaling theory with insights derived from the attention based view, this study addresses the question of which types of upper echelons ties initial public offering (IPO) markets value more. Specifically, we argue that the signals conveyed by upper echelons ties with publicly traded firms are perceived by IPO equity markets as more valuable than upper echelons ties with privately held firms. Additionally, we contend that the signals sent by external directorates with publicly traded firms are perceived more favorably by IPO equity markets than managerial ties with publicly traded firms. The theory in this study is tested on a sample of 366 firms than underwent their IPOs during 1997. The results of hypothesis tests provide partial support for our arguments.     

Ross risk vulnerability for introductions and changes in background risk

We present two theorems that provide necessary and sufficient conditions for an expected utility maximizer to become more risk averse in the sense of Ross with respect to bearing a foreground risk after the introduction of any independent fair or unfair additive background risk. We call these decision makers Ross risk vulnerable, and show that Ross decreasing absolute risk aversion and Ross decreasing absolute prudence are jointly sufficient for Ross risk vulnerability. Restrictions on utility necessary and sufficient for Ross risk vulnerability with respect to stochastic dominance deteriorations of an existing background risk are also presented. Our analysis concludes with applications of Ross risk vulnerability.     

The development of the Personality Audit: a psychodynamic multiple feedback assessment instrument

The Personality Audit (PA) was developed to meet a need for a relatively simple multiple feedback instrument that could clarify the various motivational needs of executives. Using a psychodynamic approach to leadership, the PA allows the test-taker to assess him- or herself in seven personality dimensions important in human behaviour and to identify personal ‘blind spots’. The resulting insights can be used to formulate appropriate leadership development goals.

The objective of this paper is to describe the design and psychometric properties of the PA. This instrument, in contrast with other tools that can be used to clarify the inner theatre of individuals, is designed not only to report information given by the test-taker but also to reflect the perceptions of observers representing both the test-taker's public and private spheres. This paper describes in detail the conceptual foundations of the questionnaire, the psychometric methods used to confirm its validity and reliability, and possible directions for future research.     

Introduction to the special issue on positive conflict—Conflict and employees: The right and processes to be heard

Conflict, defined as clash, competition, or mutual interference of opposing or incompatible forces or qualities, may be positive. The appropriate amount of conflict may be a delicate balance not easily achieved. Thus, a key issue is conflict management. The major charter of this special issue is the presentation of work which suggests or demonstrates that conflict can be a positive force in the modern organization. It also is pointed out that conflict, positive or otherwise, and its resolution involves a broad spectrum of inquiry into the rights and obligations of those involved in the conflict     

A Simple Econometric Approach for Utility-Based Asset Pricing Models

Utility-based models of asset pricing may be estimated with or without assuming a distribution for security returns; both approaches are developed and compared here. The chief strength of a parametric estimator lies in its computational simplicity and statistical efficiency when the added distributional assumption is true. In contrast, the nonparametric estimator is robust to departures from any particular distribution, and it is more consistent with the spirit underlying utility-based asset pricing models since the distribution of asset returns remains unspecified even in the empirical work. The nonparametric approach turns out to be easy to implement with precision nearly indistinguishable from its parametric counterpart in this particular application. The application shows that log utility is consistent with the data over the period 1926–1981.     

Cost of Transacting and Expected Returns in the Nasdaq Market

This article empirically examines the liquidity premium predicted by the Amihud and Mendelson (1986) model using Nasdaq data over the 1973–1990 period. The results support the model and are much stronger than for the New York Stock Exchange (NYSE), as reported by Chen and Kan (1989) and Eleswarapu and Reinganum (1993) . I conjecture that the stronger evidence on the Nasdaq is due to the dealers' inside spreads on the Nasdaq being a better proxy for the actual cost of transacting than the quoted spreads on the NYSE, since the Nasdaq dealers do not face competition from limit orders or floor traders.
