Exchange Rate Pass-Through to Consumer Prices in South Africa: Evidence from Micro-Data

Abstract

A sizeable literature examines exchange rate pass-through to disaggregated import prices, but few micro-studies focus on consumer prices. This article explores exchange rate pass-through to consumer prices in South Africa, for 2002–2007, using a unique data set of highly disaggregated data at the product and outlet level. The empirical approach allows pass-through to be calculated over various horizons for different goods and services. The heterogeneity of pass-through for food sub-components is considerable. Switches between import and export parity pricing of maize are found significant for five out of ten food sub-components. Using actual weights from the CPI basket, overall pass-through to the almost 63 per cent of the CPI covered is about 30 per cent after two years, and higher for food.     

Intellectual Property,Access to Medicines,and Health: New Research Horizons

In this introduction, we review the literature on intellectual property rights and access to medicines, identifying two distinct generations of research. The first generation analyzes the origins of new intellectual property rules, in particular the World Trade Organization’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the significance of TRIPS to developing countries. The second generation examines national-level experiences, as countries adjust their laws and practices to conform to TRIPS. Based on the insights provided by the articles in the special issue, we contribute to the second generation by considering a pair of overarching sets of issues. First, we highlight the domestic political challenges that affect how countries go about implementing their new obligations under TRIPS. We argue that alliances and coalitions are necessary to underpin the use of policy instruments designed to conform to TRIPS while taking into account local conditions and needs, and we present insights that allow us to understand why alliances and coalitions are difficult to construct and sustain in this area. Second, we explain why policies that many countries adopt in response to TRIPS often do not generate their desired or intended outcomes. In the last section of the introduction, we review the articles that appear in this special issue.     

Best Friends’ Discussions of Social Dilemmas

Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4 % female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents’ social and moral development.     

Examining Multiracial Youth in Context: Ethnic Identity Development and Mental Health Outcomes

Although multiracial individuals are the fastest growing population in the United States, research on the identity development of multiracial adolescents remains scant. This study explores the relationship between ethnic identity, its components (affirmation, exploration), and mental health outcomes (anxiety, depressive symptoms) within the contexts of schools for multiracial adolescents. The participants were multiracial and monoracial minority and majority high school students (n = 4,766; 54.6 % female). Among the participants, 88.1 % were Caucasian, 7.4 % were African American, and 4.5 % were multiracial. The research questions examined the relationship between ethnic identity exploration and affirmation on mental health outcomes and explored the role school context plays in this relationship. The findings suggested that multiracial youth experience more exploration and less affirmation than African Americans, but more than Caucasians. In addition, multiracial youth were found to have higher levels of mental health issues than their monoracial minority and majority peers. Specifically, multiracial youth had higher levels of depressive symptoms than their African American and Caucasian counterparts. Multiracial and Caucasian youth had similar levels of anxiety but these levels were significantly higher than African Americans. School diversity did not influence mental health outcomes for multiracial youth. These findings provide insight into the experiences of multiracial youth and underscore the importance of further investigating factors that contribute to their mental health outcomes.

Liberal Democracy Series I, 1972–1988: Definition, measurement, and trajectories

The purpose of this paper is to provide the definitional and empirical background to the Liberal Democracy Series I Index of democracy that is available in Bollen (1998) but whose rationale has not been published. More specifically, the paper (1) gives a definition of liberal democracy that has guided the formation of this index, (2) describes measures that correspond to this definition, (3) provides a measurement model that links the indicators of democracy to the latent variables that represent the concept, (4) explains the construction of the Liberal Democracy Series I Index, and (5) compares the Series I democracy measure to two other widely used democracy measures in a latent curve model. The Liberal Democracy Series I Index provides a simple unweighted measure of liberal democracy that minimizes the bias in expert ratings, is highly reliable and highly correlated with the latent liberal democracy variable. The evidenced reviewed here suggests that its measurement properties are superior to the Polity and Vanhanen democracy indices with the exception that it is available for a more limited period of years than these latter two.     

The rights and wrongs of robotics: Ethics and robots in public organizations

Some electronics experts believe that robots, like present‐day computers, will be commonplace. A diverse assortment of robots, with varying purposes, capacities, forms, and sizes, is emerging with significant implications for the policy, service and regulatory responsibilities of government. This paper explores three public policy fields – aging, health care and defence – where the use of robotics is already substantial or where it is projected to grow substantially and where significant ethical issues exist or are anticipated. Applying ethical theories to the use of robotics is difficult. In the near‐term, the focus should be on the ethical standards and behaviour of those designing, manufacturing, programming and operating robots. Several key topics in contemporary public sector ethics, including personal moral responsibility, privacy and accountability, are central to the emerging field of robot ethics. This suggests developing an ethics regime for robotics and examining the need for laws and regulations governing its use.
