Intrametropolitan migration: A simultaneous model of employment and residential location of white and black households

This study explores the relationship between the home and job location of the household within a metropolitan area. The model is an extension of the Alonso-Muth framework and allows the household to simultaneously choose its residential and employment location, monthly rent, number of rooms and the type of structure of the dwelling unit, so as to maximize its utility subject to the budget constraint.The data base is the Home Interview Survey conducted in 1965 by the (San Francisco) Bay Area Transportation Study Commission. The coefficients in the simultaneous model are estimated by two-stage least squares. The cross-section sample is stratified by tenure into renters and homeowners; by race into black and white households; and further by position in the life-cycle.The results of the location equations reveal that both the home and job location are responsive to each other which implies that the decentralization of jobs will result in the decentralization of residences for black households. The results of the housing equations imply that black and white households have almost identical elasticity of demand for housing. There is very slight evidence of price discrimination against black households. However, there is evidence that black households do face a geographical segregated market for rental housing.The results of this study argue that the decentralization of population is not due solely to rising incomes and will continue as long as industry decentralizes. Furthermore, governmental policies of increasing the income of central city residents, through subsidies to employers to locate in the central city will have a strong effect: inducing those residents to remain in or move into the central city. Thus, a policy that is meant to alleviate the plight of the city center may only result in strengthening the racial and income split between the suburb and the central city inhabitants.     

Toward a direct contribution-reinforcement pay system

To make a pay system a source of reinforcement for contribution and give people an opportunity to participate in a reward program each year without the stigma of becoming “too expensive,” firms might consider making less than 100% of the total amount increase distributed to an individual a permanent part of his base salary. A part of the raise could be in effect for, say, a year.     

The impact of the Interaction between institutional quality and aid volatility on growth: theory and evidence

We analyze both theoretically and empirically, the effect of aid volatility and its interaction effect with institutional quality on per capita economic growth. Our theoretical model, in which an aid-recipient government, operating in an institutional environment of some given quality (making choices over the distribution of aid), predicts that a negative effect of aid volatility on growth is mitigated by stronger institutional quality. We use panel data covering the period 1984–2004 for 78 countries to test this theoretical prediction. Using Generalised Methods of Moments (GMM) we find the relationship between growth and aid volatility is significantly negative and depends on institutional quality. Our baseline results are robust to various computations of aid volatility and foreign aid, time periods, sub-samples and additional covariates.     

Bridging the gap between Gen X and Gen Y

The implications of the generational diversity inherent in the fabric of the current workforce have been a topic of much discussion, exploration, and debate among organizational scholars and researchers. What are the leadership implications of this generational diversity, and what forms of leadership can be used constructively to achieve performance outcomes that foster a positive and constructive relationship between generations? We turn to the theoretical developments associated with the Authentic Leadership model to synthesize learning lessons from the theory, research, and practice of authentic leadership. We illustrate how the components of authentic leadership can help in overcoming some of the leadership challenges that result due to the differences between Gen Xers and Gen Yers.     

What drives support for self-driving car technology in the United States?

Abstract

Recent advances in automotive technology have made fully automated self-driving cars technologically feasible. Despite offering many benefits such as increased safety, improved fuel efficiency, and greater disability access, public support for self-driving cars remains low. While previous studies find that demographic factors such as age and sex influence self-driving car support, limited research has examined variables that are well known to predict public attitudes toward emerging technology. Using self-report data from a quota sample of American adults (N?=?1008), we find that age and sex are not significantly associated with support for self-driving car policies when controlling for these other variables. Instead, significant predictors of support included trust in automotive institutions and regulatory bodies, recognition of self-driving car benefits, positive affect toward self-driving cars, and a greater perception that human-driven cars are riskier than self-driving cars. Importantly, we also find that individualism is negatively associated with support. That is, people who value personal autonomy and limited government regulation may perceive policies encouraging self-driving car use as threatening to their worldviews. Altogether, our results suggest strategies for encouraging greater public support of self-driving vehicles while also forecasting potential barriers as this technology emerges as a fixture in transportation policy.     

The Interplay of Emotion Regulation and Sales Experience in Salesperson Conflicts: Evidence from an Emerging Economy

ABSTRACT

It is human nature that personal interactions are often charged with emotions and laden with conflicts. Workplace encounters are not immune from this reality. Despite this, few studies have examined ways to reduce interpersonal conflict in the workplace. This study examines the interpersonal impact of emotion regulation on salesperson relationships with stakeholders. Using structural equation modeling, results of the analysis showed that salesperson's regulation of emotions was negatively related to interpersonal conflict with co-workers as well as with customers; and positively impacted customer-oriented sales behaviors. The results also support the moderating role of selling experience in the relationship between emotion regulation and interpersonal conflict with customers. That is, the negative relationship between regulation and conflict with customers is stronger for salespeople with lower sales experience. These findings put forward important managerial implications with regard to the recruitment and training of sales professionals.     

Kenya's focus on urban vulnerability and resilience in the midst of urban transitions in Nairobi

ABSTRACT

Addressing urban vulnerability requires an understanding of the underlying determinants of resilience for individuals, households, communities and institutions – to withstand shocks, to adapt and to change. Analysing urban resilience utilises the results of five rounds of the Indicator Development for Surveillance of Urban Emergencies surveys conducted in three informal settlements of Nairobi. Results show a significant deterioration in food security and household hunger in marginalised urban populations, with other deprivations including insecurity, negative coping behaviour and inadequate access to water and sanitation. Within slum populations, there was a significant variation in income and expenditure (p?<?0.05) with lowest income quintiles spending over 100% of their income on food. Significant gender disparities have been shown in lowest income quintiles, with female breadwinners earning 62% compared with male breadwinners (p?<?0.05). Recommendations from this analysis include establishing thresholds for vulnerability and concrete dimensions for measuring resilience that can initiate and guide related interventions.     

The association between the severity of chronic kidney disease and medical costs among patients with type 2 diabetes

Aims: Examine healthcare costs across chronic kidney disease (CKD) stages for US patients with type 2 diabetes (T2D).

Materials and methods: IQVIA Real World Data Adjudicated Claims linked electronic medical records and insurance claims from January 1, 2012 through March 31, 2017 were used for this retrospective study. Adults diagnosed with T2D and comorbid CKD were included. General linear models incorporating splines were constructed, and information from these regressions were used to inform the relationship between medical costs and CKD. Multivariable analyses controlled for patient characteristics, vital signs, general health, prior medication use, prior visit to specialists, index A1c, and year of index date.

Results: There were 6,645 individuals who met the study criteria. Results generally indicate sharp increases in annual total medical costs and non-drug medical costs in the 1?year post-period for patients with Stage 4 or 5 CKD (estimated glomerular filtration rate [eGFR]?≤?30?mL/min/1.73 m²) with each 1 point reduction in eGFR from 30 associated with an increase of $1,870 in all-cause total medical costs (p?<?0.0001) and $1,805 of all-cause non-drug medical costs (p?<?0.0001). Similarly, each point decline below 30?mL/min was associated annual cost increases of $1,701 for CKD-related total medical costs, $1,695 for CKD-related non-drug medical costs, $173 for diabetes-related medical costs, and $187 for diabetes-related non-drug medical costs (all p?<?0.0001).

Limitations: The investigation included only patients with medical insurance and laboratory test results, and results may not be generalizable to all T2D patients with CKD. The methodology allowed us to determine associations, not causation, and potential confounders, such as duration of diabetes, diet, exercise, or social support, could not be assessed.

Conclusions: Results indicate there are sharp and significant increases in medical costs among T2D patients with Stage 4 and 5 CKD compared to those with earlier stages of CKD.
