Testing the validity of responses to contingent valuation questioning

One way of assessing the validity of results generated through the application of the Contingent Valuation Method (CVM) is through the analysis of response sensitivity to factors expected to have an influence. Scope testing involves presenting at least two alternative impact scenarios to population sub-samples and testing for differences between the estimates generated. Most applications of the CVM in Australia have not involved scope testing and those that have yielded mixed results. These studies are reviewed. The results of scope sensitivity and other validity tests are presented for a study aimed at estimating the value of environmental damage caused by dryland salinity in the Upper South East of South Australia.     

Teaching the Implicit Assumptions Underlying Firm Behavior in the Neoclassical Model

The neoclassical model imposes narrow assumptions on firm behavior and in the process hides implicit assumptions regarding the behavior of individuals. Although the firm is a complicated organization composed of many individuals, the neoclassical model simplifies its behavior to one objective—the maximization of profits. This assumption implicitly assumes that individuals within the firm subordinate their own self-interest for the firm’s benefit. A classroom activity is described which assists students in discerning whether the assumption of profit maximization fits reality.     

Heterogeneous ambiguity attitudes: a field experiment among small-scale stock investors in China

We conducted quasi-field experiments in Chinese brokerage houses to investigate how investors react to ambiguity relative to quantifiable risks and the degree of heterogeneity in these reactions. Our experiment consists of three sections; a background survey; individual self-reports of emotional states; and a series of individual portfolio choice questions involving ambiguous assets and assets with a known probability of success. We calculate an index of ambiguity aversion that controls for risk aversion through a series of simple choices and demonstrate its outside validity. We find a significant degree of heterogeneity in ambiguity attitudes and discuss some demographic or emotional factors that might contribute to this heterogeneity. We also discuss the correlation between ambiguity attitudes and risk attitudes. By conducting these experiments in China, we were able to measure the degree of ambiguity aversion among a sample of experienced and accessible investors who face ambiguous decisions on a daily basis.     

Digging deeper or piling it higher? Implicit measurement in organizational behavior and human resource management

Organizational researchers can dig deeper into peoples' thoughts, attitudes, and self-concepts to understand how automatic processes may impact judgment and social behavior in organizations. Measures of these automatic processes, including the Implicit Association Test (e.g., IAT; Greenwald, McGhee, & Schwartz, 1998), Semantic Priming (e.g., SP; Wittenbrink, Judd, & Park, 1997), Affect Misattribution Procedure (e.g., AMP; Payne, Cheng, Govorun, & Stewart, 2005), Word Completion Tasks (e.g., WCT; Johnson & Saboe, 2011), among many others, deserve greater attention as alternatives or supplements to traditional self-report measures of variables important in organizations (e.g., job satisfaction, personality and trait measurement, diversity attitudes). In this paper, we first provide a primer on implicit social cognition and its relationship to automatic and controlled cognitive processes, discussing major types of implicit measures, how these might operate, criticisms of this approach, and how these implicit constructs may give rise to behavior in organizations. Second, we discuss models of automatic processes and explore their validity and how these may predict behavior. Third, we offer advice for selecting, constructing, and improving implicit measurements when used in organizational research to enhance human resources and organizational functioning.     

The limits of the wage impact of discrimination

In spite of almost 40 years of active enforcement efforts by the EEOC, as well as the strong intervention by the plaintiff bar, the most popular benchmark by which we measure the influence of prejudice on wages paid to female and minority workers has changed very little. This paper maintains that to a large extent this seeming immunity of discriminatory wage gaps to the legal remedies provided by Title VII results from the mismeasurement of those effects. An alternative to the standard Oaxaca decomposition of the wage gap is offered which allows us to put plausible ranges around the true impact of antidiscrimination laws. Not only does this reduce the residual impact of the discrimination that appears to withstand Title VII remedies, it also suggests that the pre‐Title VII impact of discrimination on wages accounted for little of the gap observed at the time of its passage.

But are they Meritorious? Genetic Productivity Gains under Plant Intellectual Property Rights

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using varietal trial data from Washington State. As the private open‐pollinated varieties exist only because of PVP and are higher yielding, these results indicate a clear public benefit from PVP.     

Strategic and Business Planning Practices of Fast Growth Family Firms

Fast-growth family firms were surveyed about their business and strategic planning practices. Of the 65 fast-growth family firms surveyed, the majority prepare written formal plans. The business plans are in sufficient detail to enable the business to tie planning to actual performance and to adjust management compensation accordingly. The majority of the firms regularly share information with employees regarding comparisons between actual company performance results and goals or planned performance. Further, the majority of the firms describe their business strategy as a high quality producer strategy rather than as a low-cost or time-based strategy. Further, when bringing new products to market, these fast-growth family firms adopt a first mover or early follower strategy. Implications of these findings for growth-oriented family firms are presented.     

Discussion of “biases in multi-year management financial forecasts: Evidence from private venture-backed U.S. companies”

Armstrong, Dávila, Foster, and Hand (“ADFH”) use a proprietary venture capital database of revenue and profit projections submitted by young firms seeking financing to attempt to address a number of questions related to forecasts by managers of early stage, venture-backed, private entrepreneurial firms. The proprietary dataset together with the creative use of a “historically-grounded conditional projections” methodology are the most interesting features of ADFH’s study. However, these same aspects give rise to empirical design constraints that the study does not fully overcome. In addition, there are numerous leaps of logic required to arrive at some of ADFH’s conclusions and there are alternative explanations for ADFH’s findings that have not been entirely refuted. This leaves the reader with some doubt as to whether all of ADFH’s conclusions are fully substantiated. Nevertheless, the evidence presented makes an interesting contribution to our understanding of the forecasting behavior of young, private, rapidly growing, VCbacked firms, and provides some natural economic and methodological leads into further studies of these issues.     

Maternity rights and mothers' return to work

This paper uses a cohort of 12,000 births to examine the effect of maternity rights on mothers' post-birth return to employment decisions. It uses a discrete hazard model to disentangle the effects of the terms of maternity rights entitlements from other factors that influence the timing of a mother's return to work. Mothers with rights have an underlying (but unobserved) stronger attachment to the labour market that prompts earlier return than on average. We take this into account by estimating a counterfactual distribution of return times using a sample of women who failed to qualify for maternity rights but who have similar levels of labour market attachment. Even when differential attachment is taken into account there remains a substantial impact of maternity rights on behaviour.
