Residential land use with demographic dynamics of young and old generations

Populations of many countries are expected to decrease rapidly, with a simultaneous increase in the proportion of elderly people. These population dynamics will affect residential location patterns of young and old people because of their different preferences for local (zonal) amenities. Using an overlapping generations model in a closed city with two zones, this paper demonstrates how younger and older generations reside in the two zones and classifies the residential patterns into three patterns. Results of analyses underscore how the three residential patterns arise according to the respective population dynamics and zone amenities. Furthermore, by exploring the equilibrium utility paths of young and old people for each residential pattern, we show that the change in the population dynamics can produce an unfair change over generations with different birthdates.

Bricolage in the urban cultural sector: the case of Bradford city of film

Abstract

This article discusses bricolage in the context of a social enterprise for urban development. It focuses on the case of BDK Limited, and discusses how this organisation contributes to the economic and social development of the British city of Bradford by promoting city-wide film-based cultural consumption and cultural pride. This research used semi-structured interviews, participant observation and documentary analysis to examine this organisation’s different modes of material and ideational bricolage. The entrepreneurs serve as material bricoleurs as they transform the residuals of the city’s industrial past from materials of no use and reminders of backwardness to sites for cultural consumption. This paper also identifies patterns of ideational bricolage. In Bradford, ethnic diversity has long been discursively associated with conflicts and backwardness by local businesses, potential investors, the media and even urban social entrepreneurs themselves. However, in this case study, diversity is re-perceived as a cultural asset for urban tourism and related industries.     

The Geometry of Comparative Industrial Relations: Efficiency,Equity and Voice

This article focuses on John Budd’s efficiency, equity and voice concepts. The discussion considers the concepts’ utility as a framework for analyzing different national patterns of industrial relations in a comparative perspective. The article considers eight forms of employment relationships: social partnerships, sectoral bargaining, centralized awards, enterprise unionism, exclusive representation, codetermination, the US new deal system and voluntarism. The author concludes that this is a useful framework for such purposes, and that it is following the industrial relations tradition of pluralism.     

Landlords, tenants and the public sector in a spatial equilibrium model of rent control

A spatial model is used to explore the effects of urban rent control. When landlords and tenants can alter economic and location decisions, policy effects in controlled and uncontrolled zones may differ from standard predictions. Tenants in both zones may benefit from the control, even after unfavorable landlord adjustments, but these gains are likely to come at the expense of landlords and the public sector. Efforts to restore profits and fiscal balance, without negating utility gains to renters, may fail unless control distortions can be adequately shifted to absentee landowners through lower site rents. Lump-sum renter subsidies may offer equivalent utility gains with less severe impacts on landlords and the public sector, but the supply elasticity of land again matters.     

Spatial-equilibrium analysis of transferable development rights

Transfer of development rights (TDR) programs combine low-density incentives with zoning flexibility to generate a market for development rights and to redirect land-use patterns. A differentiated spatial-equilibrium model is used to study the impacts of brokered and unbrokered TDR programs on rents, consumption/location patterns, household utility, and property-tax revenues. Properties of the TDR market, the relationship of TDR systems to uncontrolled and zoned economies, and questions regarding the optimal control of a TDR program are also examined.     

A project management research framework integrating multiple theoretical perspectives and influencing factors

The increasing projectification of the business world corresponds with a high diversity of theoretical perspectives used in project management research. This diversity is reflected by a variety of influencing factors, which have been the subject of empirical studies. This article aims to systemize the different streams of research on the basis of a literature review and at developing a research framework by integrating multiple theoretical perspectives and influencing factors. We elaborate on the crosslinks between the perspectives and identify fundamental elements of a project management theory. The framework consists of three dimensions: design, context, and goal. Its purpose is to support the combination of different perspectives and the development of strategies for further research.     

A PRIMER ON MATHEMATICAL MODELLING IN ECONOMICS

Abstract The Commission on Graduate Education in Economics had raised several concerns regarding the role of mathematics in graduate training in economics ( Krueger, 1991 ; Colander, 1998, 2005 ). This paper undertakes a detailed scrutiny of the notion of a utility function to motivate and describe the common patterns across mathematical concepts and results that are used by economists. In the process one arrives at a classification of mathematical terms which is used to state mathematical results in economics. The usefulness of the classification scheme is illustrated with the help of a discussion of Arrow's impossibility theorem. Common knowledge of the patterns in mathematical concepts and results could be effective in enhancing communication between students, teachers and researchers specializing in different sub‐fields of economics.     

Advantageous redistribution with three smooth CES utility functions

We present a parametric example of three-country advantageous redistribution with two Cobb–Douglas utility functions and one CES utility function for which the elasticity of substitution is 1/2. This paper indicates that the possibility of advantageous redistribution strongly depends on the three countries’ taste patterns, endowment distributions, and the elasticity of substitution. In particular, we will show with specific examples that greater difference between the donor and recipient’s taste patterns and a lower elasticity of substitution can increase the chance of advantageous redistribution.     

A gradient boosting approach to the Kaggle load forecasting competition

We describe and analyse the approach used by Team TinTin (Souhaib Ben Taieb and Rob J Hyndman) in the Load Forecasting track of the Kaggle Global Energy Forecasting Competition 2012. The competition involved a hierarchical load forecasting problem for a US utility with 20 geographical zones. The data available consisted of the hourly loads for the 20 zones and hourly temperatures from 11 weather stations, for four and a half years. For each zone, the hourly electricity loads for nine different weeks needed to be predicted without having the locations of either the zones or stations. We used separate models for each hourly period, with component-wise gradient boosting for estimating each model using univariate penalised regression splines as base learners. The models allow for the electricity demand changing with the time-of-year, day-of-week, time-of-day, and on public holidays, with the main predictors being current and past temperatures, and past demand. Team TinTin ranked fifth out of 105 participating teams.     

Employment equity,human resource development and institution building in South Africa

The process of economic and social reconstruction in South Africa (SA) has harnessed capital, organized labour and state agencies in emergent tripartite macro-policy forums; in particular, the National Economic Development and Labour Commission. Public policy on human resource development, affirmative action and diversity issues is increasingly an outcome of negotiations in these structures. However, although significant legislative developments on these issues are envisaged in the near future, institutional adaptation has not been adequately researched. The apartheid state was constructed on the ideological basis of ethnic fragmentation rationalized by ethnic and cultural diversity. At the same time, diversity is a social reality in building common national and organizational goals, symbols and identity.

This paper discusses structural and labour market factors associated with the process of employment equity and diversity management in South African organizations. A research project, the Breakwater Monitor, at the Graduate School of Business, University of Cape Town, has established a national database covering some one million employees, which enables benchmarking of company and sectoral practices in regard to affirmative action, diversity policy, training and development and skills formation. The project has also begun to track diversity representation at all levels across major sectors longitudinally, using a common job evaluation standard for comparability. The project considers both quantitative and qualitative factors in human resource development. Findings from this project are presented and discussed in the context of human resource development.     

Institutions and International Trade: A Reconsideration of Comparative Advantage

Abstract. Persistent inconsistency between predictions of standard theoretical models and empirical evidence of international trade dynamics suggests that the traditional understanding of the determinants of actual international trade patterns is incomplete. What is missing? A recent literature suggests paying more attention to the role of the domestic institutional environment. The level and nature of development of the relevant institutions may be shown to affect competitiveness, by altering both production and transaction costs. In the extreme case, alternative institutional architectures that emerge in different countries may be interpreted as the cause of relative advantage/disadvantage even if technological levels, factor endowments and tastes are identical everywhere. Although in standard international trade models institutions remain implicit, it is hard to explain trade patterns and international competitiveness without taking institutions explicitly into consideration. By reviewing and reorganizing the most interesting contributions on this issue, this survey discusses how institutional diversity affects comparative advantage and international trade dynamics.     

“A GEM” for increasing the effectiveness of diversity training

Questions about diversity training's utility and effectiveness remain despite its widespread use and the significant investments many firms make in such training. As a result, some HR practitioners have doubts about its relevance in the workplace. In this paper, we envision a future state of diversity training whereby diversity is embedded into work practices and programs through direct knowledge transfer, continuous skill development, and accountability for learning. We recommend four specific guidelines that HR leaders can follow to achieve this “future state” called A.G.E.M.—Approach, Goals, Executive Commitment, and Mandatory Attendance. We suggest that following the A.G.E.M. approach will lead to the kind of transformative behavioral changes required for effective diversity training programs.     

Profit,productivity, and profit-sharing

This study is an investigation of the effect of profit-sharing on labor productivity. When monitoring labor performance is costly for management, a regular wage/salary contract is insufficient to induce profit-maximizing behavior from the worker. The authors demonstrate that when this profit-maximizing behavior can be induced only through profit-sharing, a linear profit-sharing program will increase productivity and the welfare of both management and labor. The benefit from profit-sharing is increasing up to the point where the utility of additional income is offset by the negative utility of extraordinary effort (working harder or providing higher quality work). The income effect, i.e., the change in negative utility of extraordinary effort given a change in income, can potentially either increase or decrease the point at which the income-effort tradeoff-reaches zero.

Strategic alliances: managing complementarity to capitalize on emerging technologies

There are many different ways for firms to enter emerging industries and many possible patterns of rivalry within such industries. Although the literature gives prominence to the pioneering role of small start-ups, the fact is that large firms have often tried to pioneer new industries, by leveraging on the achievements of their central research facilities. Some firms have sought an organizational complement to progressiveness in the R&D lab. This complement is the internal venture. However, internal ventures pose the difficulty of internal diversity. Strategic alliances, on the other hand, permit the firm to exploit new technologies in new industries with a minimum of internal diversity. They have the benefit of speedy access to technology or to market expertise, minimizing risk and financial exposure, and providing a greater focus when bringing resources to bear on innovation. Strategic alliances provide alternatives for collaboration between firms with minimal contamination of the pioneering and entrepreneurial spirit of new technology-based firms.     

Assessment of development regions for financial support allocation with fuzzy decision making: A case of Turkey

European Union is a project focused on the balanced distribution of the prosperity, established by the common market, to all regions. For this purpose, in order to collect comparable statistics, socio-economic zones have been established within the framework of certain criteria using the classification of Nomenclature of Territorial Units for Statistics (NUTS). These regions are formed in 3 levels, based on the countries that are members and candidates for membership. Supports provided within the framework of the EU in order to reduce regional socio-economic disparities and to ensure regional development are being made and measured on the basis of regions (development zones) established with Level 2 NUTS. As a candidate country to the EU, Turkey also tries to achieve harmonization and regional development through Instrument for Pre-Accession Assistance (IPA). In this study, the extent to which the development regions identified in the Turkish scale should benefit from such supports is assessed on the basis of specific criteria. How to distribute IPA support, which is a limited resource, to the regions according to framework agreements and regional development goals is a complex issue. In order to solve this problem, development zones are evaluated using two different Multi Criteria Decision Making methods: Fuzzy-PROMETHEE and Fuzzy-MULTIMOORA. As a result, a framework to provide specific distribution of funds to support regional development and to show the weaknesses of these regions is presented.     

Organizational diversity programs across cultures: effects on absenteeism,turnover, performance and innovation

This study examined data from over 5000 organizations in 22 countries to address three complementary issues: (1) the influence of national culture on the adoption of diversity programs aimed at recruiting, training and promoting individuals from specific target groups; (2) the moderating effect of national cultural practices on the relationship between these diversity programs and the organizational outcomes of absenteeism and turnover; and (3) the mediating effect of absenteeism and turnover on the relationship between diversity programs and organizational performance and innovation. National cultural values and practices were taken from the GLOBE study and assigned respectively to the organizations in our sample. A multilevel path analysis supported the hypothesized effects of national cultural values on organizational diversity programs. Moreover, cultural practices were found to moderate the relationship between diversity programs and absenteeism and turnover. Our hypotheses on the role of absenteeism and turnover as mediators of the relationship between diversity programs and organizational performance and innovation were also supported. Our findings may help guide managers' decisions on the adoption of diversity programs in units operating in different national cultures. We discuss the implications of our findings for scholars and practitioners concerned with diversity management issues in a global context.

Trade-offs and disappearing acts: shifting societal discourses of diversity in Canada over three decades

In the past few decades, research on minority and disadvantaged groups in the workplace has focused on the discourse of diversity management; however, most of this research has emphasized individual and organizational discourse rather than broader, societal contexts. Our critical analysis of societal/macro level discourse explores the discursive constructions of equity and diversity in Canada, and provides original findings on how these discourses have been produced in the public sphere. We apply quantitative and qualitative textual analysis to articles published from 1986 to 2014 in The Globe and Mail, a nationally distributed newspaper, and the Canadian Employment Equity Act Annual Reports from 1988 to 2013. This paper describes a range of discursive patterns including those focusing on compliance-based equity oriented toward social justice as well as voluntary ‘diversity management’ grounded in corporate self-interest. It demonstrates important trade-offs in who is protected and promoted through the contrasting discourses, and in the types of actors legitimizing these discourses. We provide detailed evidence of these patterns by applying Habermas’ Theory of Communicative Action, and conclude with a discussion of implications for practice and for theory that are suggested in our analysis.
