Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries

Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment.     

Measuring the Value of Product Characteristics in the Presence of Price Dispersion

Modeling the price of multi‐attribute products generally requires an assessment of each attributes' market value. In the presence of price dispersion, when similar products are sold at different prices, hedonic pricing models provide users with biased estimates of attribute value. This paper develops the hedonic pricing literature by proposing data envelopment analysis as a prior means of identifying a sub‐sample of products which, after adjusting for attribute provision, display no price dispersion. These products then display a homogenous link between attributes and price, which can be modeled using hedonic pricing. This paper implements and evaluates this two‐stage approach using 1000 observations from the UK mortgage market. Copyright © 2014 John Wiley & Sons, Ltd.     

Adjusting for risk in comparing the performances of male- and female-controlled SMEs

Small and medium enterprise (SME) research has typically found that female-owned SMEs underperform male-owned SMEs. Further, this underperformance usually persists after controlling for variables such as industry, age of business, and size of business. However, previous studies have normally limited their assessment of performance to sales or profit (or growth in sales or profit) without controlling for differences in risk. Our results indicate that although profits are significantly higher for male-controlled SMEs, so is the variation in profits (risk). After adjusting for risk, we find no significant difference between the performances of male- and female-controlled SMEs.     

The Theoretical Ground for Public Relations Practice and Ethics: A Koehnian Analysis

Public relations literature laments the lack of a theoretical base for the practice and ethics of public relations. Drawing primarily upon Koehn (The Ground of Professional Ethics, 1994) and Hutton (Public Relations Review, 1999), this paper proposes such a theoretical ground.The paper adopts Hutton's assertion that "the central organizing theme of public relations theory and practice" is relationships(Hutton, 1999, p. 209). It also relies upon Koehn (1994) to provide a theoretical discussion of the nature of professions, and the ground upon which professional ethics and public trust in the professions are based. It concludes, from a Koehnian perspective, that for public relations to move from the expertise and contractual models of practice into a covenantal model as a profession worthy of public trust, the field must devote itself to a defined human good (relationships), and must be grounded in a public pledge to serve this good.     

Applications of business analytics in healthcare

The American healthcare system is at a crossroads, and analytics, as an organizational skill, figures to play a pivotal role in its future. As more healthcare systems capture information electronically and begin to collect more novel forms of data, such as human DNA, how will we leverage these resources and use them to improve human health at a manageable cost? In this article, we argue that analytics will play a fundamental role in the transformation of the American healthcare system. However, there are numerous challenges to the application and use of analytics: the lack of data standards, barriers to the collection of high-quality data, and a shortage of qualified personnel to conduct such analyses. There are also multiple managerial issues, such as how to get end users of electronic data to employ it consistently to improve healthcare delivery and how to manage the public reporting and sharing of data. In this article, we explore applications of analytics in healthcare, barriers and facilitators to its widespread adoption, and ways in which analytics can help us achieve the goals of the modern healthcare system: high-quality, responsive, affordable, and efficient care.     

Dilemmas in the management of temporary work agency staff

Temporary jobs account for an increasing proportion of new engagements in the UK labour market, with temporary work agencies or 'labour market intermediaries' occupying a central role in the regulation of entry into some organisations. Such evolving arrangements have been found to have their contradictions, even for the host organisation. This article explores the internal and external pressures to use a temporary work agency as a means of recruiting labour at host organisations. It considers some of the HRM issues that stem from the use of such workers, including the tendency to devolve HRM to the managers of such agencies operating within the host organisation. Central to this article is a consideration of the potential sustainability of organisations' use of temporary agency workers, engaging with this concern from the perspective of organisational cost‐effectiveness.     

Non-fatal violence-related injuries in Kingston,Jamaica: a preventable drain on resources

Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH.     

Why do diners tip: rule-of-thumb or valuation of service?

When diners decide how much to tip, is the decision based on social convention or on conscientious appraisal of server productivity? Previous researchers in economics and social psychology are generally inconclusive on this question. A common finding in the literature is that tip size and service quality are unrelated, a result usually obtained from OLS regressions. OLS is only appropriate if service quality is exogenous. It is argued that service quality is very likely endogenous in any regression of tip size; good quality encourages good tips, but server expectations of good tips encourage good quality. This simultaneity is accounted for by jointly estimating percentage tips and customer rankings of service quality on a sample of 247 diners in a Central Minnesota restaurant. Included are explanatory variables consistent with both the social psychology and economic views of tipping. In contrast to previous studies, it is found that service quality significantly affects tip size and when servers expect higher tips, customers rank service quality higher. Also it is found that patronage frequency and coupon redemption have no effect on percentage tips, but server gender influences quality significantly. It is concluded that the results are generally supportive of an economic hypothesis of tipping.     

Real Estate Rental Payments: Application of Stock-Inventory Modeling

This paper analyzes the rental term structure taking into account the opportunity costs faced by the tenant for varying lease lengths. The analysis involves the application of a multi-period stock inventory model. The implication of the model is that the term structure of rents is determined by a clientele effect that can bias the occupancy value derived from using rational-expectations in the term structure relationship. The model does, however, reveal the characteristic stock-inventory U-shaped function that will determine the optimal lease length for a given tenant.
