Measurement of market integration and arbitrage

We develop a measurement theory of market integration, basedon two notions of 'integrated markets'. First, two markets cannotbe perfectly integrated in any sense if one can construct twoportfolios, one from each market, that have identical payoffsbut different prices. In that case, the law of one price isviolated across the markets. Second, they cannot be integratedin a stronger sense if there are cross-market arbitrage opportunities.Two measures of market integration are developed, respectivelyreflecting these notions. The smaller the measures, the moreclosely integrated (in the respective senses) the markets. Amongother things, they are interpreted as measuring pricing discrepancybetween markets.     

Interpretation problems of the partial correlation with nonnormally distributed variables

The partial correlation is a commonly used measure for assessing the bivariate correlation of two quantitative variables after eliminating the influence of one or more other variables. The partial correlation is generally interpreted as the correlation that would result if the variables to be eliminated were fixed (not allowed to vary and influence the other variables), which is referred to in the statistical literature as conditional correlation. The present paper demonstrates, by means of theoretical derivations and practical examples, that when the assumption of multivariate normality is violated (e.g., as a result of nonlinear relationships among the variables investigated) the usual interpretation of the partial correlation coefficient will be basically incorrect. In extreme cases the value of the partial correlation coefficient may be strongly positive, close to 1, whereas the conditional correlation may have a large negative value. To solve this problem the paper suggests to partial out a certain function (in most cases the square) of the variables whose effects are to be eliminated if nonlinear relationships are likely to occur.     

Is an Auditor's Propensity to Issue Going Concern Opinions a Valid Measure of Audit Quality?

A number of previous studies use auditor propensity to issue a going concern opinion (GCO) as a proxy of audit quality when examining a sample of financially distressed firms. This study examines whether audit quality (measured by discretionary accruals) influences the probability of financially distressed firms receiving GCOs using a non‐specific sample of 2937 firm‐year observations from Australia over the period 2011–2015. The study first investigates the association between financially distressed firms and the issuance of GCOs. This association is then re‐tested after separating the total sample into low and high audit quality subsamples. The results indicate that financially distressed firms are more likely to receive GCOs, confirming the application of ASA 570 Going Concern. However, financially distressed firms that receive GCOs from their auditors are limited to firms that have higher‐quality audits.     

Payments or Persuasion: Common Pool Resource Management with Price and Non-price Measures

We use lab experiments to study policies that address common pool resource overuse. We look at a price mechanism, specifically a Pigouvian subsidy, and four non-price interventions. The non-price policies are information alone, information with a normative message, communication alone, and normative messages with communication allowed. In all experiment sessions, no intervention occurs in the first seven and last seven rounds, allowing us to examine the effects of introducing and taking away a policy. The subsidy leads to near-efficient extraction, but surprisingly leads groups that were not over-extracting to also reduce extraction. This over-compliance decreases efficiency, although on net the subsidy is the most efficiency-enhancing intervention. Information provision, communication, normative appeals, and normative appeals combined with communication all reduce over-extraction (though by less than the subsidy) without exacerbating over-compliance; however, the effects of information alone and communication alone are small and not robust. The non-price policies cause a decline in over-extraction of from 0.549 (information) to 11.441 % (normative appeals with communication). These effects are of the same order of magnitude as the effects seen in major field studies of conservation messaging. The subsidy has the worst persistence properties (after the intervention ceases), while normative messages with communication have the best.     

The dampening effect of iceberg orders on small traders’ welfare

Iceberg orders, which allow traders to hide a portion of their order size, have become prevalent in many electronic limit order markets. This paper investigates, via a real options analysis, whether small traders, who have no use for submitting iceberg orders, are better off submitting their orders to fully transparent markets which have low depth, or to more liquid markets which do permit the placement of iceberg orders by large traders. Surprisingly, we find that in the context of our model, small traders are better off submitting to fully transparent markets in spite of them being less liquid.     

Do company ethics training programs make a difference? An empirical analysis

The authors analyze results of a survey of members of the Columbia University Graduate School of Business classes of 1953–1987 in order to assess the potential effectiveness of firms' ethics training programs. Results suggest that such training has a positive effect, but that relatively few firms provide such programs (about one-third of the respondents worked for firms with such programs). Although the sample is not representative of American employees and managers generally, the results suggest that it may be worthwhile for firms to provide formal ethics training to their employees.John Delaney is Associate Professor of Management and Organizations at The University of Iowa. His research on ethics in business has been published in Across the Board and Iowa Business. As part of an ongoing study, he is collecting examples of ethical dilemmas that have been confronted by managers in recent years.Donna Sockell is Director of Credit Programs and Professor of Management and Labor Relations at Rutgers, the State University of New Jersey. In addition to her research on ethics in the workplace, she has designed and taught ethics programs for several corporations and commodities exchanges. Currently, she is gathering information on how firms' ethical practices affect employees.     

Impact Fees and the Price of New Housing: An Empirical Study

Development exactions in the form of impact fees are being used increasingly by local governments to fund the cost of providing public services necessitated by growth and development. This paper presents the results of an empirical study designed to ascertain the extent to which impact fees are capitalized into the price of new, single-family dwellings. On June 3, 1974, the city of Dunedin, located in Pinellas County, Florida, began assessing impact fees of $1,150 against all new, single-family construction. Using data on 5,839 new home sales in Dunedin and three other cities in Pinellas County from 1971–1982, it was found that builders were able to pass forward the total cost of impact fees to new home buyers. However, the price differential due to impact fees for new dwellings in Dunedin compared to the price of new dwellings in the other three cities disappeared after approximately six years. This is explained by the nature of the fee structure in Dunedin, adjustments in factor costs, increases in the price of housing in competing cities, and unrealized expectations regarding the benefits to be provided by impact fee collections.     

Technology forecasting: Aircraft hazard detection

This article describes the use of the scoring model technique to forecast aircraft hazard detection technology. The various factors relating to hazard detection were determined. These factors were combined into a single parameter which describes the relation of these factors to the technology being forecasted. The method of determining the value of each factor for the various detection systems utilized in the forecast are discussed. These include factors which were normalized, others which require judgemental evaluation, and one which was computed. The results of the forecast are presented, showing that the parameter derived adequately describes the hazard detection systems on which it was based.     

Therapy,Enhancement, and Medicine: Challenges for the Doctor–Patient Relationship and Patient Safety

There are ethical guidelines that form the foundation of the traditional doctor–patient relationship in medicine. Health care providers are under special obligations to their patients. These include obligations to disclose information, to propose alternative treatments that allow patients to make decisions based on their own values, and to have special concern for patients’ best interests. Furthermore, patients know that these obligations exist and so come to their physicians with a significant level of trust. In this sense, therapeutic medicine significantly differs from straightforward business practices such as the buying and selling of houses, cars, cell phones, etc. However, we argue that this relationship differs when medicine is used for enhancement rather than therapy. When patients seek enhancements they are not as vulnerable as when they are ill. And in an enhancement setting, physicians have little role outside of medical risks to discuss motivation and alternatives. Therefore, we conclude that a more reasonable alternative may be for doctors and patients to use ethical norms associated more with straightforward business practices, specifically sales. We believe that full disclosure of this different set of norms will benefit both physicians and patients.     

Information Technology, US Union Organizing and Union Effectiveness

This paper examines the effects of information technology (IT) on organizing and union effectiveness in US national unions. Original survey data and data from government and independent sources are combined to model outcomes including membership growth, success in representation elections, and union leaders' assessments of effectiveness as a product of environmental and organizational characteristics. The results suggest that the practical impact of IT use on organizing outcomes can be quite important. Evidence regarding the impact of IT on overall effectiveness (i.e. organizational or union effectiveness) is more mixed.
