The migration and development nexus in Southern Africa Introduction

The role of international and internal migration in facilitating or inhibiting development is currently attracting considerable attention globally. In southern Africa, the migration–development nexus has been researched for a number of years and policy makers in both the development and migration fields are now paying it increasing attention and increasingly recognising the significance of migration for development and poverty reduction. Much of the international debate on this nexus is hampered by the absence of sound, reliable national and local data. This collection of essays by southern African researchers combines the national with the local, the quantitative with the qualitative, and addresses several prominent themes in the global migration–development debate: remittances, the brain drain and migrant rights. It also focuses on key migration–development issues which have received less attention globally, but which are of critical importance to southern Africa: migration and HIV/AIDS, migration and food security and the rural impact of migrant retrenchments. This Introduction to the collection contextualises the essays within current international and local debates.     

IMPACT OF THE MINIMUM WAGE ON THE INCIDENCE OF SECOND JOB HOLDING IN BRITAIN

The advent of any earnings boost, such as provided by the introduction of a minimum wage, might be expected to reduce the supply of low‐paid individuals wanting to hold a second job. This paper uses difference‐in‐differences estimation on a panel of individuals matched across successive Labour Force Surveys around the time of the introduction of the national minimum wage in the United Kingdom in order to estimate the impact of the minimum wage and its subsequent upratings on second job working. There is little evidence to suggest that the extra pay provided by the introduction of the minimum wage was sufficient to affect the incidence of second job holding significantly. However, hours worked in the main job by second job holders may have risen relative to those not covered by the minimum wage; and hours worked in second jobs may have fallen for those whose second job was initially below the minimum.     

Foreign Direct Investment,Economic Growth,and the Human Capital Threshold: Evidence from US States*

The United States has experienced a dramatic increase in foreign direct investment (FDI) in recent years. While foreign firms bring immediate benefits of high‐paying jobs, data limitations have prevented detailed study on FDI's long‐term effects on the states receiving it. By creating a new stock measure of FDI based on employment, we are able to capture these long‐term effects. Results demonstrate that FDI has a greater impact on per capita output growth than domestic investment for US states that meet a minimum human capital threshold. Ironically, the most active states in the recruitment of FDI tend to fall below this threshold.

哈佛商学院——保护公司的战略性支出

在经济衰退时期，许多经理的本能反应是削减公司各个层面的支出。由于没有对短期运营性支出和长期战略性支出加以区分，这种“一刀切”的削减行为很可能会铸成大错。我们认为，除非衰退已经威胁到公司的生存，否则经理们应该专注于寻找并克服公司运营的无效率，而不是牺牲公司的战略性项目，因为后者决定着公司的长期竞争力。     

Motivation in project management: The project manager's perspective

Project motivation is a key aspect to a successful project, yet few studies exist that shed light on this important subject. This article reviews the current literature and theoretical aspects of motivation and provides an analysis of the data. A survey was conducted by soliciting project managers to tell how they perceive their ability to influence motivation. In total, 115 certified project managers responded to the survey. A discussion and suggestions for future research follow the data.     

Abortion Access and Risky Sex Among Teens: Parental Involvement Laws and Sexually Transmitted Diseases

Laws requiring minors to seek parental consent or to notifya parent prior to obtaining an abortion raise the cost of riskysex for teenagers. Assuming choices to engage in risky sex aremade rationally, parental involvement laws should lead to lessrisky sex among teens, either because of a reduction of sexualactivity altogether or because teens will be more fastidiousin the use of birth control ex ante. Using gonorrhea rates amongolder women to control for unobserved heterogeneity across states,our results indicate that the enactment of parental involvementlaws significantly reduces risky sexual activity among teenagegirls. We estimate reductions in gonorrhea rates of 20% forHispanics and 12% for whites. Although we find a relativelysmall reduction in rates for black girls, it is not statisticallysignificant. We speculate that the racial heterogeneity hasto do with differences in family structure across races.     

Consumer perceptions of higher and lower-level designed store environments

The role and influence of esthetics in the consumption of store environments remains poorly understood. Little is known about how esthetics propose substantial or adjunctive roles in consumers’ store experiences. The aim of this paper is to examine consumer perceptions of store design-architecture in high and low-level design contexts. Building on the esthetics, and environmental psychology literatures, our findings confirm consumers’ determinations of perceptual differences in the esthetic content contained in presented store environmental stimuli. Latent means comparisons confirm consumers’ perceptions of the presence of a high-level design in one fast-fashion store with a low-level design of a second store of the same retailer using a Confirmatory Factor Analysis. The results demonstrate the reliability and validity of the proposed constructs in confirming the presence of higher and low-levels of design. This research, thus, expands on the extant number of store specification and response constructs and prospectively opens up new lines of store environments research.
