TL;DR: The Market Failures Approach (MFA) has been criticised by Abraham Singer on the basis that it unjustifiably does not assign private managers obligations based on egalitarian values as mentioned in this paper, and Singer proposed an extension to the MFA, the justice failures approach (JFA), in which managers have duties to alleviate political, social, and distributive inequalities in addition to having obligations to not exploit market failures.
Abstract: The Market Failures Approach (MFA) is one of the leading theories in contemporary business ethics. It generates a list of ethical obligations for the managers of private firms that states that they should not create or exploit market failures because doing so reduces the efficiency of the economy. Recently the MFA has been criticised by Abraham Singer on the basis that it unjustifiably does not assign private managers obligations based on egalitarian values. Singer proposes an extension to the MFA, the Justice Failures Approach (JFA), in which managers have duties to alleviate political, social, and distributive inequalities in addition to having obligations to not exploit market failures. In this paper I describe the MFA and JFA and situate them relative to each other. I then highlight a threefold distinction between different types of obligations that can be given to private managers in order to argue that a hybrid theory of business ethics, which I call the MFA + , can be generated by arguing that managers have obligations based on efficiency and duties based on equality to the extent that these latter obligations do not lead to efficiency losses. This argument suggests a novel theoretical option in business ethics, elucidates the issues that are at stake between the MFA and the JFA, and clarifies the costs and benefits of each theory.

TL;DR: The results of data analysis using structural equation modelling through partial least square PLS approach suggest that perceived network size and perceived innovativeness of services have significant effects on the users' continuance of intention to use mobile messaging apps.
Abstract: As mobile messaging apps e.g., WhatsApp are becoming increasingly popular with the widespread adoption of smart phones, competition to gain a larger user-base gets more intense among app providers. To win the competition by leveraging their user bases, messaging app providers pursue a platformization strategy through which they offer a variety of services e.g., games, shopping, etc. to their messaging app users. The main objective of this study is to gauge the effect of the platformization strategy on the messaging app users. To do so, we first identify several factors e.g., perceived network size, innovativeness, service variety and convenience to locate services that can characterise the platformization strategy. We then develop a research model that focusses on the effects of the factors on users' intention to continue to use messaging apps. This research model is tested with data collected from 148 users through an online questionnaire survey. The results of data analysis using structural equation modelling through partial least square PLS approach suggest that perceived network size and perceived innovativeness of services have significant effects on the users' continuance of intention to use mobile messaging apps.

  • ...In microeconomic literature, the consumer decision to borrow or to save is known as an intertemporal choice (Varian, 1987). A simple model of intertemporal choice behavior assumes two time periods, present and future. In the present period, con­ sumers decide whether to borrow or to save. In the future, they repay their debts or use their savings for consumption. Consumers decide the amount consumed in the present and in the future subject to their budget constraint; that is, their present and future income. Based on their consumption level and budget constraint, consumers maximize their utility. When they borrow, consumers consume more than their in­ come in the present and they have to repay the amount borrowed plus interest in the future. White (1988) suggests a similar model of intertemporal choice but he adds that the economic theory of borrowing is based on two other assumptions: (1) consumers desire to smooth consumption over more than one period, (2) consumers prefer present consumption over future consumption....

  • ...57, which indicated that 57% of the variance in total debt was explained by all socioeconomic and psy­ chological variables. All independent variables except race of the respondents were significant in explaining total debt. Gender of the respondents was positively related to total debt and the coefficient was significant at 0.001 level. The positive relationship between males and the total debt suggests that male respondents had a higher total debt than female respondents. Controlling for other variables, male respondents were more likely to have a higher debt than female respondents. Controlling for other variables, male respondents had about .33% more debt than female respondents. This finding is consistent with Bloom and Steen (1987) who found that male respondents had a higher amount of debt than...

TL;DR: In this article, the authors identify factors that determine business success and failure in South Sudan using survey logistic and generalized linear mixed models and multiple correspondence analysis (MCA) models.
Abstract: Just over half (50.6%) of the population of South Sudan lives on less than one US Dollar a day. Three quarters of the population live below the poverty line (NBS, Poverty Report, 2010). Generally, effective government policy to reduce unemployment and eradicate poverty focuses on stimulating new businesses. Micro and small enterprises (MSEs) are the major source of employment and income for many in under-developed countries. The objective of this study is to identify factors that determine business success and failure in South Sudan. To achieve this objective, generalized linear models, survey logistic models, the generalized linear mixed models and multiple correspondence analysis are used. The data used in this study is generated from the business survey conducted in 2010. The response variable, which is defined as business success or failure was measured by profit and loss in businesses. Fourteen explanatory variables were identified as factors contributing to business success and failure. A main effect model consisting of the fourteen explanatory variables and three interaction effects were fitted to the data. In order to account for the complexity of the survey design, survey logistic and generalized linear mixed models are refitted to the same variables in the main effect model. To confirm the results from the model we used multiple correspondence analysis.

TL;DR: Differences in patient preferences for the components of a total knee arthroplasty care episode are demonstrated and distinct preference profiles among patient subsets can be characterized to help providers design customized bundles guided by preference profiles.
Abstract: Background Episode-based bundled payments for total knee arthroplasty emphasize cost-effective patient-centered care. Understanding patients' perceptions of components of the total knee arthroplasty care episode is critical to achieving this care. This study investigated patient preferences for components of the total knee arthroplasty care episode. Methods Best-worst scaling was used to analyze patient preferences for components of the total knee arthroplasty care episode. Participants were selected from patients presenting to 2 orthopaedic clinics with chronic knee pain. They were presented with descriptions of 17 attributes before completing a best-worst scaling exercise. Attribute importance was determined using hierarchical Bayesian estimation. Latent class analysis was used to evaluate varying preference profiles. Results One hundred and seventy-four patients completed the survey, and 117 patients (67%) were female. The mean age was 62.71 years. Participants placed the highest value on surgeon factors, including level of experience, satisfaction rating, and complication rates. Latent class analysis provided a 4-segment model of the population. Conclusions This study demonstrated differences in patient preferences for the components of a total knee arthroplasty care episode and characterized distinct preference profiles among patient subsets. Stakeholders can use this information to focus efforts and policy on high-value components and to potentially create customized bundles guided by preference profiles. Clinical relevance This study is clinically relevant because the patient preferences identified here may help providers to design customized bundles for total knee arthroplasty care.
