Does neighborhood income mix affect earnings of adults? New evidence from Sweden

This paper contributes to the literature on obtaining unbiased estimates of neighborhood effects, explored in the context of a centralized social welfare state. We employ a longitudinal database comprised of all working age adults in metropolitan Sweden 1991–1999 to investigate the degree to which neighborhood income mix relates to subsequent labor incomes of adults and how this relationship varies by gender and employment status. We control for unobserved, time-invariant individual characteristics by estimating a first-difference equation of changes in average incomes between the 1991–1995 and 1996–1999 periods. We further control for unobserved time varying characteristics through an analysis of non-movers. These methods substantially reduce the magnitude of the apparent effect of neighborhood shares of low-, middle- and high-income males. Nevertheless, statistically and substantively significant neighborhood effects persist, though relationships are nonlinear and vary by gender and employment status. Males who are not fully employed appear most sensitive to neighborhood economic mix in all contexts.     

A model of residential change and neighborhood tipping

This paper applies the theory of probabilistic consumer demand to an analysis of residential change at the urban neighborhood scale. By developing the profit maximizing pricing behavior of housing suppliers, it is shown that neighborhood transitions from high income to low income and from white to black can be explained on purely economic grounds without involving prejudicial preferences. The analytical model explains two types of transition. In the first, a neighborhood's social mix changes gradually in response to gradual exogenous changes. In the second, a neighborhood “tips” suddenly in response to similar exogenous changes. The two transitions can occur depending on the characteristics of the demand functions for the two competing groups.     

Trust,individualism and job characteristics as predictors of employee preference for teamwork

Employee resistance has long been recognized as a key constraint on the success of organizational change initiatives. However, it is only recently that employee attitudes towards working in teams has been specifically investigated as a factor influencing team effectiveness. Using data from 218 employees in 40 self-managing work teams, we examined the relationship between trust, individualism, job characteristics and team members' attitudes towards teamwork. Providing a partial test of Mayer et al.'s (1995) relational model of trust, the results indicate that the two situational forms of trust (trust in co-workers and trust in management) were stronger predictors of an employee's preference for teamwork than propensity to trust. Trust in co-workers was found to partially mediate the relationship between a person's propensity to trust strangers and their preference for working in a team. The importance of considering the dispositional variables of propensity to trust and individualism as factors that influence an employee's preference for teamwork, as well as their trust in management, trust in co-workers and their opportunity for skill utilization are discussed.     

The role of neighborhood characteristics in mortgage default risk: Evidence from New York City

Using a rich database of non-prime mortgages from New York City, we find that census tract level neighborhood characteristics are important predictors of default behavior, even after controlling for an extensive set of controls for loan and borrower characteristics. First, default rates increase with the rate of foreclosure notices and the number of lender-owned properties (REOs) in the tract. Second, default rates on home purchase mortgages are higher in census tracts with larger shares of black residents, regardless of the borrower’s own race. We explore possible explanations for this second finding and conclude that it likely reflects differential treatment of black neighborhoods by the mortgage industry in ways that are unobserved in our data.     

Residential preferences, neighborhood filtering and neighborhood change : Comment and corrections

The purpose of this Comment is to correct the estimating technique used by Little in “Residential Preferences, Neighborhood Filtering and Neighborhood Change.” Little uses the factor load matrix rather than the factor score matrix in his computations of the implicit regression coefficients. We correct Little's estimates and also present additional results to compare his corrected results with principal component estimates and ordinary least squares.     

What makes a good conference? Analysing the preferences of labour economists

Conferences are an important element in the work of researchers, requiring substantial investments in fees, travel expenses and the time spent by the participants. The aim of this paper is to identify the preferences of participants with respect to conference characteristics. Based on a sample of European labour economists, preferences are measured using the vignette approach where participants are asked to choose between hypothetical European Association of Labour Economists (EALE) conferences. We find that the keynote speakers are the most important element in the preference for a conference, followed by the location of the conference. There is substantial heterogeneity in the taste of labour economists especially with respect to location, though the link between preference parameters and measured characteristics like gender, age and seniority is limited. Factor analysis suggests that the variety in preferences can be best described by a latent variable that reflects the weights people put on content versus fun.     

Dynamic decision and coordination in a low-carbon supply chain considering the retailer's social preference

We establish dynamic game models in a low-carbon supply chain consisting of a single manufacturer and a single retailer with social preference. This study investigates the complex dynamic characteristics of pricing decision and carbon abatement strategy in the supply chain and focuses on the impact of the retailer's social preference on pricing decision, carbon emission abatement strategy, profits, supply chain coordination, and complexity of dynamic models. We find that adjustment parameters of pricing and carbon emission abatement should be maintained in a certain range; otherwise, the system will be unstable and even chaotic through period double bifurcation or wave shape chaos. A higher social preference of the retailer is always beneficial to carbon abatement and the manufacturer and helps maintain the stability of the supply chain system. However, the impact on the long-term profitability of the supply chain is related to the state of the system. Compared with the setting of a centralized decision, the optimal carbon abatement strategy and supply chain profit in a decentralized decision are always less than those in a centralized setting, regardless of whether the retailer has social preference. Therefore, a side-payment self-executing contract is designed to coordinate the supply chain and achieve Pareto improvement. The coordination mechanism proposed in this study not only leads to Pareto improvement but also increases the stability of the supply chain system. Finally, this study enlightens management in operating a low-carbon supply chain.     

Consumers’ fluid milk consumption behaviors in TURKEY: an application of multinomial logit model

Although consumers’ fluid milk consumption behavior related to skim milk, low fat milk and whole milk have attracted a lot of attention in the last decade, relatively a few studies have examined the consumers’ unprocessed and processed fluid milk consumption. The objective of this study was to analyze consumers’ fluid milk consumption and preference in Turkey by using cross-sectional national survey data. The Chi-square test of independence and multinomial logit procedure were used to investigate the selected socioeconomic and demographic characteristics of consumers that determine households’ fluid milk consumption choices between unprocessed fluid milk, processed fluid milk and non-consumption choices. Empirical results indicate that unprocessed fluid milk preference is related positively to household size, number of children in family, household income, and age of housewife; and negatively to education level and employment status of housewife. On the other hand, processed fluid milk preferences are related positively to household income, number of children in households and education level of housewife and negatively to household size and age of housewife.     

Consumer choice of dwelling,neighborhood and public services

Previous microeconomic analyses of consumer choice in the housing market have either assumed the independence of irrelevant alternatives or have represented housing heterogeneity by some arbitrary aggregation of dwellings. This paper presents an empirical analysis of housing choice based upon individual households and dwellings which also estimates the degree of independence of neighborhood and dwelling characteristics. The empirical results suggest that the independence assumption may be inappropriate and also that housing choice may be more sensitive to variations in workplace accessibility than is indicated by the more restricted model of household choice.     

Entry mode choices in the international new ventures context. A study from different theoretical perspectives

Few studies have investigated the factors that enhance entry mode choice in the context of international new ventures (INVs). In this paper, we hypothesize that the characteristics of INVs’ products or services can explain their preference for equity entry modes. We also hypothesize that the inter-firm networks in which INVs are embedded play a deciding role in their choice of non-equity entry modes. When INVs are in inter-firm networks in which activities are developed to manage them, non-equity entry modes are preferred. We have adopted an effectuation approach to study the influence of different inter-firm network management activities on entry mode choice. In short, we have studied the effect of developing inter-firm network knowledge exchange, coordination, adaptation, conflict resolution and resource sharing management activities. In this paper we attempt to contribute to international entrepreneurship studies by reconciling the most widely accepted approaches to entry mode choice (Transactional Cost Economics, Organizational Capabilities-based and Network perspective) and international new ventures. Our findings show that the technological complexity of INVs’ products/services explain their preference for equity entry modes. Additionally, the development of network management activities among the networked firms determines the INVs’ preference for non-equity entry modes. Our results draw a decision model that differs from the ones derived from previous perspectives, which highlight the role of different characteristics of international new ventures.     

Asset prices in an exchange economy when agents have heterogeneous homothetic recursive preferences and no risk free bond is available

We study a pure exchange economy under incomplete markets where households have heterogeneous homothetic recursive preferences and lending and borrowing are precluded. We fully characterize the properties of the efficient allocations and the equilibrium asset price. The ownership distribution dynamics reveal the emergence of a dominant agent, who after some finite time, remains the only investor that increases asset holdings until asymptotically owning the entire wealth. Investors can be ranked according to a unique parameter that aggregates agents’ preference characteristics and we show how time discount rate, attitude towards risk and intertemporal substitution contribute to capital accumulation.     

IT Contract Flexibility and Negotiator Incentives

Information Technology outsourcing contracts are plagued by inflexibility. We develop an economic model to explain how the contract negotiator's incentives influence contract flexibility. We show that neither wage nor one‐time commission type pay gives any preference for flexibility. However, a promotion incentive, where the bonus is an ongoing bonus, does give the negotiator a preference for less flexible contracts. The preference for less flexible contracts increases as the discount rate increases. The preference for less flexible contracts increases as the number of competitors for the promotion increases.

A facility location problem with clients' preference orderings

The Simple Plant Location Problem (SPLP) consists in identifying a pattern of facilities among a set of potential sites so that the sum of the costs for opening the facilities and for supplying a group of geographically dispersed clients therefrom is minimized. It is posited in this framework that the locator rules on the allocation of the clients to the facilities. When the clients are free to decide upon which facility they will attend, their choices do not necessarily match the most economical supply pattern from the point of view of the locator. We suppose here that each client has a preference ordering on the list of potential sites whereby he determines his allocation out of any set of open facilities. This preference ordering depends on characteristics of the client, of the sites, and of the trip between the client's location and the sites. Mathematically, we translate the orderings into a set of constraints to be appended to the SPLP. This new problem, termed SPLPO, has a wide range of applications as shown by a series of examples. We present an algorithm for solving the SPLPO and extensive computational experiments are reported.     

Helping hand or grabbing hand?: Politicians, supervision regime, financial structure and market view

Almost all the literature on the evolution of the financial supervision architecture stresses the importance of financial market characteristics in determining the recent trend toward more unification. But in the real world it is not always clear to what extent market features matter. We present two complementary approaches to gain insights in the above relationship, focusing on the political cost and benefit analysis. First, a cross-country study tests two alternative theories—the helping hand and the grabbing hand view of government—to determine the impact of the market structure on the supervisory setting. Our evidence seems more consistent with the grabbing hand view, considering the degree of banking concentration a proxy of the capture risk and presuming the market demonstrates a preference for consolidation of supervisory powers. Second, the results of a survey among financial CEOs in Italy confirm a market preference for a more consolidated supervisory regime but reveal only weak consistency between the views of the policymakers and those of the market operators.     

Updating Choquet beliefs

We apply Pires’s coherence property between unconditional and conditional preferences that admit a CEU representation. In conjunction with consequentialism (only those outcomes on states which are still possible can matter for conditional preference) this implies that the conditional preference may be obtained from the unconditional preference by taking the Full Bayesian Update of the capacity.

Perceived neighborhood quality in the United States: Measuring outdoor, housing and jurisdictional influences

Theory suggests that perception of neighborhood quality is influenced by crime, blight, and other outdoor characteristics, by respondent perception of the quality of their housing, and by attributes of the local jurisdiction. It also suggests that these geographical attributes should be confounded by respondent demographic characteristics. Using 48,000 sample responses collected by the American Housing Survey in 2002, ordinary least squares, factor analysis, and hierarchical linear modeling, we connected these strands of theory and found strong associations between neighborhood quality, detrimental conditions, housing quality, socioeconomic status, and age. We also measured a small anti-big city effect, and a few weaker relationships with growing/healthy and demographic homogeneity effect. The application of complex statistical tools, in short, enabled us to obtain insight about how people build mental models of their neighborhoods.     

Mixture models of choice under risk

This paper is concerned with estimating preference functionals for choice under risk from the choice behaviour of individuals. We note that there is heterogeneity in behaviour between individuals and within individuals. By ‘heterogeneity between individuals’ we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By ‘heterogeneity within individuals’ we mean that the behaviour may be different even by the same individual for the same choice problem. We propose methods of taking into account all forms of heterogeneity, concentrating particularly on using a Mixture Model to capture the heterogeneity of preference functionals.     

PMP® certification as a core competency: Necessary but not sufficient

This research seeks to investigate the relationship between project management certification and established project management core competencies in the IT industry. This study was conducted in two phases, the objective being to first identify those characteristics most common to the successful hire of project managers, from the perspective of IT recruiters. Once identified, the study sought to determine preference for these characteristics from the point of view of corporate IT executives. Two hypotheses were tested in an effort to determine the valuation of Project Management Professional (PMP®) certification as a core competency and as an indicator of project success. Both hypotheses were rejected, as results indicated that PMP® certification was the least valued of 15 core competencies and that there was no difference in project success rates between PMP®‐certified project managers and uncertified project managers. In addition, recruiters' and IT executives' suggestions for improvement in the delivery of the project management body of knowledge are discussed.
