Who takes workplace case‐study methods seriously? The influence of gender,academic rank and PhD training

We examine whether differences in the reporting of workplace case‐study research methods are associated with gender, experience, academic rank and PhD training. Using a random sample of published articles, we find that women take more care reporting their research methods in the context of a general increase in methods reporting.     

Entrepreneurial Response to “Bottom-up” Development Strategies in Zimbabwe

Group lending and business training programs aimed at small-scale entrepreneurs have captured the interest of development scholars, practitioners, and donors since the 1980s. Yet these strategies have not had much impact in the context of urban Zimbabwe. Building upon ethnographic research conducted in Harare, Zimbabwe and insights drawn from the Austrian school of economics, the case is made that group lending and business training programs in urban Zimbabwe fail to meet the needs of most informal entrepreneurs because they offer a poor cultural fit with the target population, and because they are rarely able to cultivate entrepreneurial skills such as innovation and market discovery among their clients.     

“Trilemmas”: Characterising the Japanese Concept of “amae” with a Three-Way Forced-Ranking Technique

A ‘trilemma’ procedure is introduced for collecting ‘dominance data’ (i.e. rankings of a set of items along a scale of relevance, preference, etc.). Trilemmas are three-way forced choices where the three items comprising each trilemma are selected on the basis of a multidimensional scaling solution (MDS) for the item set, ensuring that each choice is as stark and informative as possible. A questionnaire designed on this principle is easily understood and rapidly administered. The data are convenient to record and show less fluctuation among informants than existing techniques. We demonstrate the procedure with a set of 45 short generalisations about behaviour, designed for assessing child attachment. A three-dimensional ‘map’ of these items was obtained by applying MDS to multiple sets of similarity data. The same structure emerged from English-language and Japanese translations of the items. Thirty trilemmas based on this map were used to rank the items by degree of association with the Japanese concept of amae, characterising the concept in terms of its behavioural correlates.     

Reversal of 3‐day losers and continuation of 3‐day winners on the NASDAQ

Using only the 200 large-cap securities that make up the NYSE 100 and NASDAQ 100, this study investigates 130 randomly selected formation periods from January 2000 through December 2012. During these formation periods, the three worst and three best performing stocks (based on excess return) are flagged. Once flagged, the subsequent 10-day holding period excess returns are calculated. Results indicate that NYSE securities demonstrate significant return reversal, but not return momentum. Conversely, the worst performing NASDAQ securities demonstrate return reversal, whereas the best performing NASDAQ securities demonstrate return momentum. Results are robust to the number of best and worst stocks that are flagged. Results are also robust to other combinations of formation and holding period lengths.     

Introducing More IFRS Principles of Disclosure – Will the Poor Disclosers Improve?

Abstract

The current paper was prepared for the International Accounting Standards Board (IASB) Research Forum 2017 and evaluates the effects of introducing more principles of disclosure as part of the IASB Disclosure Initiative. We perform a literature review of academic research on how entities have complied with disclosure requirements in the past. The review shows high levels of non-compliance and high volatility across entities, including poor disclosers being far below the average. We find no clear pattern of higher compliance for International Financial Reporting Standards (IFRS) with more reliance on disclosure principles as compared to specific requirements (i.e. IFRS 7, IFRS 8), but note the methodological problem of measuring compliance with disclosure principles. Academic research suggests that the degree of compliance depends on entities’ incentives for providing or withholding information in combination with local conditions for primary users, auditors and regulators. Based on our review, we argue that increased reliance on entities to act in ‘good faith’ when complying with disclosure requirements, in capital-market contexts where entities may be in high-incentive situations and have low costs of non-compliance, is potentially risky in terms of how well the Standards protect primary users from poor disclosers. More emphasis is needed on ensuring that the disclosure requirements are enforceable and auditable in order to secure a certain minimum level of disclosure.     

How Well Does the Australian Aged Pension Provide Social Insurance?

Social security plays an essential role in an economy, but if designed incorrectly, it can distort individuals' labour supply and savings behaviour. We explore how well the Australian means‐tested pension system provides social insurance by changing the settings of the system and calculating the impact on welfare. In order to exclude trivial welfare gains, we keep the cost of the programmes constant. We find that the means‐tested pension system is welfare reducing, but does provide a better outcome than a PAYG system of equivalent cost. We also find that if the benefit amount is held constant, and hence the cost of the pension programme is allowed to vary, a taper rate of 1.0 is optimal. However, once we hold the cost of the programme constant, a universal benefit scheme provides the best welfare outcome.     

General and specific cancer risk perceptions: how are they related?

Understanding how people construe and act upon cancer risk is important for efforts to target risk-increasing health behaviors. Importantly, research participants are often asked to estimate their risk for cancer (in general), which could mask the fact that cancer represents a range of diseases, and that different cancer types can have distinct risk factors. It is unclear whether individuals perceive general cancer risk as being comprised of an aggregation of risk for specific cancer sites, or whether general cancer risk perceptions reflect the specific type of cancer most salient to them. In this study, general cancer risk perceptions were regressed on specific risk perceptions for colon, lung, prostate (men only), and breast (women only), using data from a nationally representative sample. We found that among men and women, all forms of cancer predicted independent variance in estimates of general cancer risk. There were also stronger relationships between general risk perceptions and each specific risk perception than between any two specific risk perceptions, suggesting that individuals differentiate between specific cancers and general cancer risk. These findings offer some confidence that people’s estimates of general cancer risk take multiple cancer types into account.     

Eco-social analysis of an East African agro-pastoral system: Management of tsetse and bovine trypanosomiasis

A key constraint for development of many East African agro-pastoral communities is African animal trypanosomiasis or nagana caused by Trypanosoma spp. and vectored by species of tsetse flies (Glossina spp.). Suppression of trypanosomiasis through trapping of tsetse fly populations was conducted from 1995 to 2005 at and near Luke, Southwest Ethiopia. Odor baited mass trapping technology was used to suppress adult fly populations to very low levels while tryponocidal drugs were used to treat trypanosome infections in cattle. Data on ecological, economic and social variables were collected and analyzed in the context of eco-social dynamics in the community.The bio-economic model of Regev et al. [Regev, U., Gutierrez, A.P., Schreiber, S.J., Zilberman, D., 1998. Biological and Economic Foundations of Renewable Resource Exploitation. Ecological Economics 26, 227-242] and Gutierrez and Regev [Gutierrez, A.P., Regev, U., 2005. The bioeconomics of tritrophic systems: applications to invasive species. Ecological Economics 52, 382-396] was used as a methodological framework for qualitative evaluation of the effects of tsetse/trypanosomiasis suppression on ecological, economic and social aspects. An objective function for single farmers was formulated to determine the optimal harvesting level of cattle, exposed to high and low levels of risk from tsetse/trypanosomiasis, as measured by the discount rate (δ) for a given base level pastoral resource (R = pasture or forage for cattle). The socially optimal objective function for resource exploitation by all farmers is that which maximizes the present value of utility of individuals expending revenues (consumption) from the revenue stream in ways that enhance the quality of life and yet assures the persistence of the resource base over an infinite time horizon (i.e., renewable resource sustainability).The bio-economic model predicts that reducing risk (δ) from tsetse and disease increased the cattle populations and their marginal value. The model also predicts that the interaction of decreased δ and increased productivity (θ) can lead to increased human and cattle populations and hence to over-exploitation of base resources (pastures) that lower environmental carrying capacity and reduced sustainability.Trap catches indicated that tsetse populations were reduced to very low levels, while the disease prevalence decreased from 29% to 10%. This led to a substantial increase in cattle including oxen populations, increased calving rates, increased milk production and increased the per-capita income. The availability of oxen allowed an increase in cultivated land from 12 ha in 1995 to 506 ha in 2005. Revenues (consumption) were invested in the purchase of more cattle and the establishment of a school for educating village children. Increases in land allocated to crops and other sources of income were also found.The bioeconomic model predicts the solution of the trypanosomiasis problems so transforms the East African agro-pastoral communities that new social structures will be required to cope with the ecological, economic and social consequences of this technological changes on sustainable development (sensu [Goodland, R., 1995. The concept of environmental sustainability. Annual Review of Ecology and Systematics 26, 1-24]). This insight should not be lost in international rural development programs.     

Ethical Structures and Processes of Corporations Operating in Australia,Canada, and Sweden: A Longitudinal and Cross-Cultural Study

Based on the ‘Partnership Model of Corporate Ethics’ (Wood, 2002), this study examines the ethical structures and processes that are put in place by organizations to enhance the ethical business behavior of staff. The study examines the use of these structures and processes amongst the top companies in the three countries of Australia, Canada, and Sweden over two time periods (2001–2002 and 2005–2006). Subsequently, a combined comparative and longitudinal approach is applied in the study, which we contend is a unique approach in the area of business ethics. The findings of the study indicate that corporations operating in Sweden have utilized ethical structures and processes differently than their Canadian and/or Australian counterparts, and that in each culture the way that companies fashion their approach to business ethics appears congruent with their national cultural values. There does, however, appear to be a convergence of views within the organizations of each culture, as the Swedish companies appear to have been more influenced in 2005–2006 by an Anglo-Saxon business paradigm than they have been in the past.
