Trend and Comparative Analysis of Inequality of Social Opportunity

This article sets out a new method for the analysis of inequality of social opportunity. The shortcomings of the previous concepts and measures attempting to assess the degree of openness of the mobility process independently of marginal effects are displayed. The suggested new approach refers to relative opportunity distributions of individuals according to their social origin. Starting from the premise that these distributions underlying the observed allocation of social positions are continuous, it is assumed that it is possible to compare them using straight lines. The various slopes of the lines represent inequality of social opportunity coefficients which permit trend and comparative analysis of the mobility process net results.     

EQUALITY OF OPPORTUNITY: POLICY AND MEASUREMENT PARADIGMS

Abstract Equality of opportunity is a widely accepted principle of distributive justice and it is the leading idea of most political platforms in several countries. According to this principle, a society might institute policies that secure an equal distribution of the means to reach a valuable outcome among its members. Once the set of opportunities have been equalized, which particular opportunity, the individual chooses from those open to her, is outside the scope of justice. Ex ante inequalities, and only those inequalities, should be eliminated or compensated for by public intervention. The recent literature on the opportunity egalitarianism often merges these questions introducing two different economic issues. On one side the design of a public policy intended to implement the equality of opportunity view and on the other side the problem of measuring the degree of opportunity inequality in a society. We describe the basic setting and assumptions of some different approaches derived by Roemer’s algorithm for public policy and then we discuss some theoretical and empirical studies to separate and test alternative paradigms on the measurement of inequality of opportunity. Accordingly, an extended critique on the causality issue on policies and measurements is taken into account.     

Extremal properties of the Theil and Gini measures of inequality

Quality & Quantity - Two popular inequality measures used in the study of income and wealth distributions are the Gini (G) and Theil (T) indices. Several bounds on these inequality measures are...     

THE LABOUR FOOTPRINT: A FRAMEWORK TO ASSESS LABOUR IN A COMPLEX ECONOMY

As addressing labour becomes crucial in the move towards sustainability, there is the need for assessment tools suitable for current complex economic systems. This article presents an input–output based framework (‘labour footprint’) for evaluating labour issues behind the production of different economic commodities, including entire supply chains. In line with the guidelines of the International Labour Organization, six labour issues are considered: collective bargaining, forced labour, child labour, gender inequality, hazardous work, and social security. This conceptual article sets to (a) define this footprint's labour dimensions, (b) cite relevant data sources, (c) describe its calculation, (d) illustrate its application through a case study, and (e) discuss this framework's relevance from ‘conscious consumption’, ‘supply chain responsibility’, and regulators' standpoints. Since it advances the evaluation of fundamental labour issues and the scope of multi-criteria analyses, this footprint may be a valuable tool for sustainability assessments.     

STATISTICAL INFERENCE VIA BOOTSTRAPPING FOR MEASURES OF INEQUALITY

In this paper we consider the use of bootstrap methods to compute interval estimates and perform hypothesis tests for decomposable measures of economic inequality. Two applications of this approach, using the Gini coefficient and Theil's entropy measures of inequality, are provided. Our first application employs pre- and post-tax aggregate state income data, constructed from the Panel Study of Income Dynamics. We find that although casual observation of the inequality measures suggests that the post-tax distribution of income is less equal among states than pre-tax income, none of these observed differences are statistically significant at the 10% level. Our second application uses the National Longitudinal Survey of Youth data to study youth inequality. We find that youth inequality decreases as the cohort ages, but between age-group inequality has increased in the latter half of the 1980s. The results suggest that (1) statistical inference is essential even when large samples are available, and (2) the bootstrap procedure appears to perform well in this setting. © 1997 by John Wiley & Sons, Ltd.     

Some Basic Issues Related to Contextual Performance and Organizational Citizenship Behavior in Human Resource Management

This article examines some basic issues that might pose conceptual challenges in applying ideas related to contextual performance and organizational citizenship behavior to human resource management. It considers labeling issues and differences between the origins and definitions of the terms, contextual performance, and organizational citizenship behavior, and argues that the labeling issues are less important than careful definition and measurement of the behavioral dimensions that these terms embrace. It also considers the conceptual status of organizational citizenship behavior and contextual performance as latent constructs or aggregate constructs according to distinctions presented by Law, Wong, and Mobley. And finally, it explores questions related to consequences of behavioral patterns connoted by these terms for organizational effectiveness and individual motivation, job satisfaction, and commitment.     

Managing diversity through human resource management: an international perspective and conceptual framework

This paper critically reviews the literature on managing diversity through human resource management (HRM). We discuss the major issues and objectives of managing diversity and examine the state of human resource diversity management practices in organizations. Our review shows that inequality and discrimination still widely exist and HRM has focused mainly on compliance with equal employment opportunity (EEO) and affirmative action (AA) legislation. Less attention has been paid to valuing, developing and making use of diversity. Our review reveals limited literature examining how diversity is managed in organizations through effective human resource management. We develop a framework that presents strategies for HR diversity management at the strategic, tactical and operational levels. Our review also discusses the implications for practice and further research.     

Justice and organizational citizenship: A commentary on the state of the science

The present article discusses the state of the science regarding the connection between organizational justice and organizational citizenship behavior (OCB) as reflected by the articles included in this issue. The research described in these articles reaches a conclusion in need of further elaboration—namely, that people will behave altruistically toward the oroganizations in which they work when they believe those organizations have treated them fairly. Various conceptual issues are discussed. These include: the willingness of people to express inequity distress by withholding OCB, the relative importance of procedural justice compared to distributive justice as a determinant of OCB (especially the social aspects of procedural justice), and the extent to which a reduction in OCB may reflect a desire to influence another individual, or the organization in general. A variety of methodological issues are also discussed. In this connection, it is suggested that correlational, questionnaire measures be supplemented by open-ended interview studies as well as laboratory investigations. Moreover, if questionnaires continue to be used, then it is recommended that attempts be made to improve the validity of both measures of justice and OCB.     

INEQUALITY, ETHNICITY AND THE FIGHT AGAINST CORRUPTION IN AFRICA: A KENYAN PERSPECTIVE

Perceptions of inequality among different ethnic groups have the power to shape the fortunes of nations by affecting the political and economic choices of both ruling elites and their voters. In ethnically heterogeneous African states with a tradition of political patronage economic inequality is manifested along ethnic and regional lines. This paper argues for a constitutional dispensation that includes both the diffusion of executive power and systematic action in regard to structural economic inequalities that have assumed an ethnic expression.     

A rational-choice model of Covid-19 transmission with endogenous quarantining and two-sided prevention

This paper offers a parsimonious, rational-choice model to study the effect of pre-existing inequalities on the transmission of COVID-19. Agents decide whether to “go out” (or self-quarantine) and, if so, whether to wear protection such as masks. Three elements distinguish the model from existing work. First, non-symptomatic agents do not know if they are infected. Second, some of these agents unknowingly transmit infections. Third, we permit two-sided prevention via the use of non-pharmaceutical interventions: the probability of a person catching the virus from another depends on protection choices made by each. We find that a mean-preserving increase in pre-existing income inequality unambiguously increases the equilibrium proportion of unprotected, socializing agents and may increase or decrease the proportion who self-quarantine. Strikingly, while higher pre-COVID inequality may or may not raise the overall risk of infection, it increases the risk of disease in social interactions.

THE DRIVERS OF INCOME INEQUALITY IN RICH COUNTRIES

Rising income inequality has recently come centre‐stage as a core societal concern for rich countries. The diagnosis of the forces driving inequality upwards and their relative importance remain hotly contested, notably with respect to the roles of globalization versus technology and of market forces versus institutions and policy choices. This survey provides a critical review and synthesis of recent research. The focus is on income inequality across the entire distribution, rather than only on what has been happening at the very top. We pay particular attention to include what has been learned from the analysis of micro‐data, to ensure that the coverage is not unduly US‐centric and to analyses of the interrelations between the different drivers of inequality. The marked differences in inequality trends across countries and time periods reflect how global economic forces such as globalization and technological change have interacted with differing national contexts and institutions. Major analytical challenges stand in the way of a consensus emerging on the relative importance of different drivers in how income inequality has evolved in recent decades.     

International purchasing offices: Literature review and research directions

International Purchasing Offices (IPOs) now play an increasingly important role in the management of international sourcing activities, both in developed and emerging economies. The relevance of this organisational solution and the relatively limited research that has been published so far in the P&SCM literature make the “IPO” topic particularly promising for future research. This paper – based on an analysis of 59 works published between 1991 and 2011 – provides the first comprehensive literature review and research agenda on this topic. The primary issues (i.e., IPO definition, activities, location choices, strengths, weaknesses, and human resources management) are identified, and a conceptual framework is proposed. Building on this analysis, some theoretical and methodological weaknesses of the existing works and some gaps in the literature are discussed. This work concludes by suggesting several future research directions.     

Can innovation improve income inequality? Evidence from panel data

Income inequality is a source of social instability and armed conflict, which in turn are detrimental to economic development. This study examines the role of innovation in income inequality in twenty-three developed countries, using a panel mean group estimator that takes cross-sectional dependence into consideration. Three income inequality indicators are used: the Standardized World Income Inequality Database (SWIID), the University of Texas Inequality Project (UTIP), and the Estimated Household Income Inequality (EHII). The innovation indicators are patent applications and patents granted. The empirical results based on the common correlated effect mean group (CCEMG) reveal that innovation widens income inequality. We also investigate whether the innovation–income inequality nexus is subject to a country’s level of globalization and financial development. The findings suggest that the interaction terms between innovation with these two variables have positive effects on income inequality, whereas innovation failed to reduce income inequality. Globalization and financial development are found to drive income inequality. The empirical results are robust to different income inequality and innovation measures as well as estimation techniques.     

Issues in the analysis of co-authorship networks

Scientific collaboration is a complex phenomenon that improves the sharing of competences and the production of new scientific knowledge. Social Network Analysis is often used to describe the scientific collaboration patterns defined by co-authorship relationships. Different phases of the analysis of collaboration are related to: data collection, network boundary setting, relational data matrix definition, data analysis and interpretation of results. The aim of this paper is to point out some issues that arise in these different phases, highlighting: (i) the use of local archives versus international bibliographic databases; (ii) the use of different approaches for setting boundaries in a whole-network; (iii) the definition of a co-authorship data matrix (binary and weighted ties) and (iv) the analysis and the interpretation of network measures for co-authorship data. We discuss the different choices that can be made in these phases within an illustrative example on real data which is referred to scientific collaboration among researchers affiliated to an academic institution. In particular, we compare global and actor-level network measures computed from binary and weighted co-authorship networks in different disciplines.     

Creating opportunities. Policies aimed at increasing openings for immigrant entrepreneurs in the Netherlands

Since the 1980s, subsequent Dutch governments have promoted self-employment of immigrants to reduce their unemployment rates. These policies have been focused on the (potential) actors themselves, i.e. the immigrants who have started or who may want to start a business. Taking mixed embeddedness as a point of departure, entrepreneurship and self-employment cannot be solely understood by focusing on the micro-level but has to include the larger macro and meso structures that impact on these actors' choices. In this paper, therefore, the focus is on the opportunity structure and on the policies that affect this set of options for starting a (small) business. A typology of policies that may alter this opportunity structure is offered.

Understanding career experiences of skilled minority ethnic workers in France and Germany

Human resource management literature pays little attention to the agency of skilled ethnic minorities in Europe in terms of explaining their career choices and outcomes. As a step towards addressing this gap, we draw on two field studies based on qualitative interviews. One of these studies draws on interviews with 49 participants in France, and the other is based on interviews with 30 participants in Germany. Through a Bourdieuan analysis, we contribute to the human resource management literature, and demonstrate the varied forms that the agency of highly skilled ethnic minorities takes, in terms of their work experiences, in the context of structures of inequality in both countries.     

Supporting decision-making for recycling-based investments

The increasing demand for environmentally friendly products and the introduction of tougher environmental laws have encouraged firms to consider the adoption of recycling issues as one of the most effective solutions for reducing their impact on the environment. Unfortunately, many companies delegate decision-making on recycling issues at an operational level. This attitude presents some problems as it could lead companies to neglect many effects resulting from the adoption of recycling-based investments. The objective of this paper is to suggest a conceptual model aimed at supporting managers in the integration of recycling issues into the overall process of strategy formation; in particular, the designed approach is divided into two main phases: the identification of the main recycling-based programmes and the definition of a framework, based on both physical and accounting measures, aimed at assessing the effectiveness of different recycling initiatives according to the main priorities of the decision-maker.     

Has Federal Student Aid Contributed to Equality in Higher Education?

ABSTRACT. TO analyze the effect of federal student aid on the structure of the higher educational system, an index of inequality of access is developed It measures the differences in the distribution of income of entering students , as compared to the U S distribution of income at thirteen different categories of institutions Its application shows that structural inequality exists in the nation's system of higher education and that while some improvements occurred in the 1970s, especially at the bottom of the system, by 1986 most of these gains had been eliminated When these indices were regressed against per capita federal student financial aid , relative student costs , and variables reflecting changes in the larger economy, using time series data, the aid variables show little or no statistical effect on the structural inequality of the nation's system of higher education, as measured by the index of inequality On the other hand, the cost variable generally has strong effect The general economic variables occasionally have significant effect
