Racial disparity in the atlanta housing market

Atlanta has the reputation of being a city of opportunity for blacks. However, in Atlanta, as well as in other cities across the nation, the nexus of racism and economic discrimination has resulted in disparities between the housing status of blacks and whites. This article examines racial disparities in the Atlanta housing market. It begins by tracing recent trends in the Atlanta-area economy and by providing background information on the local housing market. It then discusses the roles of the federal Home Mortgage Disclosure Act of 1975 and Community Reinvestment Act of 1977 in the efforts of local groups to reduce racial disparities in the housing market. The final section discusses recent local developments that might lead to improvements in the housing status of black Atlantans.     

The dialectics of globalization: what are the effects for management and organization in Germany and Japan

The globalization literature has been limited cumulative. Different disciplines have different accents, use different definitions, rely on divergent theories and focus on different units of analysis. As a corollary, they have come to divergent opinions on the concept of globalization, on its broader consequences as well as on the more specific consequences for organization and management. This article contributes to the literature by proposing a societal theory of institutional change to analyze globalization effects in a more systematical way. It explores the effects of globalization forces on organization and management in Germany and Japan in comparison to the US and the UK, by tracing their impact on the systems of corporate governance, industrial relations and human resources. The article shows that different patterns of change exist at different levels of analysis. These differences help us explain why no generalized pattern of convergence towards the same economic model should be expected.     

A critical overview of privacy-preserving approaches for collaborative forecasting

Cooperation between different data owners may lead to an improvement in forecast quality—for instance, by benefiting from spatiotemporal dependencies in geographically distributed time series. Due to business competitive factors and personal data protection concerns, however, said data owners might be unwilling to share their data. Interest in collaborative privacy-preserving forecasting is thus increasing. This paper analyzes the state-of-the-art and unveils several shortcomings of existing methods in guaranteeing data privacy when employing vector autoregressive models. The methods are divided into three groups: data transformation, secure multi-party computations, and decomposition methods. The analysis shows that state-of-the-art techniques have limitations in preserving data privacy, such as (i) the necessary trade-off between privacy and forecasting accuracy, empirically evaluated through simulations and real-world experiments based on solar data; and (ii) iterative model fitting processes, which reveal data after a number of iterations.     

Measurements and determinants of multifaceted poverty in South Africa

Poverty, despite being a multifaceted concept, is commonly measured in either absolute or relative monetary terms. However, it can also be measured subjectively, as people form perceptions on their relative income, welfare and life satisfaction. This is the first study that uses the National Income Dynamics Study data to analyse poverty across various objective and subjective methods. The paper finds that while respondents' poverty status varies across methods, blacks remain the racial group most likely to be defined as poor by at least one method. The multivariate analysis reveals that the impact of some explanatory variables, such as experience of negative events, frequency of crime victimisation, health status and importance of religious activities, is mixed across methods.     

Bayesian and Bühlmann credibility for phase-type distributions with a univariate risk parameter

Credibility theory is a statistical tool to calculate the premium for the next period based on past claims experience and the manual rate. Each contract is characterized by a risk parameter. A phase-type (or PH) random variable, which is defined as the time until absorption in a continuous-time Markov chain, is fully characterized by two sets of parameters from that Markov chain: the initial probability vector and transition intensity matrix. In this article, we identify an interpretable univariate risk parameter from amongst the many candidate parameters, by means of uniformization. The resulting density form is then expressed as an infinite mixture of Erlang distributions. These results are used to obtain a tractable likelihood function by a recursive formula. Then the best estimator for the next premium, i.e. the Bayesian premium, as well as its approximation by the Bühlmann credibility premium are calculated. Finally, actuarial calculations for the Bühlmann and Bayesian premiums are investigated in the context of a gamma prior, and illustrated by simulated data in a series of examples.     

Effectiveness of Absurdity in Advertising Across Cultures

This paper examines the effect of absurd advertising on memory and persuasion across cultures. Drawing on Hofstede's cultural dimensions, it is hypothesized that the effect of absurdity on recall is culturally invariant, whereas the effect on attitude toward the ad is contingent on the recipients’ cultural orientation. The assumptions are tested using a between-subjects experimental design, in which we manipulated type of absurdity and used the cultural dimensions as blocking variables. Data was collected from 274 students in the United States, Germany, Russia, and China. We discuss theoretical and managerial implications of these findings as well as guidelines for further research.     

Ceteris Paribus Methodology and Computerized Economics-Business Models

Professor Stanford is critical of computer programs that have been developed for use in economics and business courses. He admits to having “mixed feelings” about the use of computer models as classroom teaching devices, but recognizes their great potential. His fear is that the ceteris paribus methodology has not been adequately implemented when computer models have been constructed for use in the classroom. Consequently, he has constructed a set of computerized game models which feature “options for varying degrees of complexity.” These models, which permit progression from the simple to the complex, and which enable instructors to demonstrate the effects of changing variables, are brielly described in this article.     

The impact of network configurations on value constellations in business markets — The case of an innovation network

A growing body of scholars are advocating a better understanding of how value is created in business networks, rather than merely in business relationships or at the level of single actors. Among such networks, innovation networks, i.e. the configurations of strategic entrepreneurial nets aimed at improving the effectiveness of innovation performance, have come under scrutiny in the business marketing literature. However, research that explicitly connects value considerations with innovation network configurations is still in its infancy, with empirical evidence being notably scarce. This study is aimed at identifying if and how network configurations affect value constellation aspects in business networks, in terms of value recipients and value outcomes. We interviewed key informants representing 46 high-technology entrepreneurial firms co-located in an innovation network (Daresbury Science and Technology Park — UK). Our study identifies that different network configurations can co-exist in the same overall network; these, nevertheless, are not alternative independent structures, but rather they interact with each other through actors spanning their boundaries. Our study thus provides an understanding of network configurations relating to specific value consequences, but also provides evidence relating to the interactions between different configurations. By doing this, we establish a bridge between a business marketing and a strategy perspective on value in networks. Important managerial implications and implications for policy makers also emerge from our study.
