This paper presents a price-based assessment of product market integration in Africa using disaggregated retail prices for 91 products and 12 African cities from 1991 to 2008. We find evidence of substantial deviations from the law of one price ? product price differences between the cities averaged 76% over the period – a result that is consistent with the presence of large barriers to trade in the continent. Mean price differences across cities fell by close to a quarter over the period, but the decline was concentrated in the early 1990s with little progress subsequently, despite the regional trade policies implemented by the countries. Gravity-style estimates reveal that reductions in external tariffs and global trends towards price convergence in the early 1990s are the key contributors to the trend in price integration amongst the African cities. 相似文献

We use a version of the Global Projection Model covering the United States, Euro area and Japan to assess options for dealing with the looming risk of international deflation. The zero floor to interest rates constrains monetary policy. Confidence intervals, derived from stochastic simulations, indicate ranges of uncertainty. The results suggest a high probability of a declining price level for a couple of quarters in 2009. Suitable policy adaptations reduce the risk that this might turn into a prolonged, global deflation. These include: a price level path target for monetary policy, which would respond to previous, as well as expected, shortfalls from the desired inflation rate; a more stimulative fiscal policy; and an increase in the long-run target for inflation. 相似文献

In this article we describe a holistic, ecological framework that takes into account the surface structures and pedagogical approaches in the studio and how these elements are connected to the construction of design knowledge: epistemology. In our development of this framework, we came to understand how disciplinary underpinnings and academic culture shape the ways that studio is enacted. Using practice theory, we illustrate our framework with two examples—one in Industrial Design and another in Human Computer Interaction—that demonstrate the ways in which the studio can act as a bridge between academic and professional communities. We came to see the studio as a unique practice community that connects academic and professional contexts. We argue that successful implementation of studio-based learning involves an awareness of disciplinary canons, ontological approaches to knowledge, and the academic constraints on studio-based approaches to learning. 相似文献

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not. 相似文献

This study examines a comprehensive range of executional elements in a sample of permission-based e-mail marketing campaigns. The sample comprised almost 1000 promotional e-mails sent over an 18-month period by twenty leading U.K. e-retailers. Content analyses of the e-mail campaigns reveal that different tactics of format, address, subject lines, hyperlinks and interactivity are applied to initially attract customers' attention and then encourage further interest. Interviews with nine of the twenty marketing executives who designed the campaigns pointed to managers' reasons for use of the tactical alternatives. 相似文献

Anderson and vanWincoop developed what has become the standard framework for framing and interpreting empirical work using the gravity model. Their framework relies heavily on an assumption of symmetry among countries. For issues related to North‐South trade, this assumption is problematic. In this paper, we develop an asymmetric extension of the Anderson–vanWincoop framework appropriate to the analysis of North‐South trade, where Northern countries produce differentiated goods and Southern countries homogenous ones. In addition, we use an appropriately extended version of Baier and Bergtrand and Taylor linear expansion – thus permitting its estimation using (good old) OLS. The result is an empirical model that (i) is better suited to the analysis of North‐South trade, (ii) is easy to estimate and compute comparative statics, not requiring a customised NLS routine and, given the way the South is included, (iii) provides a simple explanation of zero trade flows between some country pairs, a fact still not fully explained in the literature. As an illustration of its use, we examine the empirical link between foreign aid and trade. 相似文献

Airports in their urban settings: towards a conceptual model of interfaces in the Australian context
In Australia, airports have emerged as important sub-regional activity centres and now pose challenges for both airport operation and planning in the surrounding urban and regional environment. The changing nature of airports in their metropolitan context and the emergence of new pressures and problems require the introduction of a fresh conceptual framework to assist the better understanding of these complex roles and spatial interactions. The approach draws upon the meta-concept of interfaces of an ‘airport metropolis’ as an organising device consisting of four main domains: economic development, land use, infrastructure, and governance. The paper uses the framework to further discuss airport and regional interactions and highlights the use of sustainability criteria to operationalise the model. The approach aims to move research and practice beyond the traditionally compartmentalised analysis of airport issues and policy-making by highlighting interdependencies between airports and regions. 相似文献

Plagiarism strikes at the heart of academe, eroding the fundamental value of academic research. Recent evidence suggests that
acts of plagiarism and awareness of these acts are on the rise in academia. To address this issue, a vein of research has
emerged in recent years exploring plagiarism as an area of academic inquiry. In this new academic subject, case studies and
analysis have been one of the most influential methodologies employed. Case studies provide a venue where acts of plagiarism
can be discussed and analyzed in a constructive manner, and that is the primary purpose of this article. Unlike previous studies,
however, we focus on the role of the publisher, a key player in dealing with acts of plagiarism, but one who has received
little attention in the academic literature. Specifically, we examine how an academic publisher addressed allegations of plagiarism
and how the publisher’s decision-making affected the outcome. We analyze the case by applying the guidelines from different
frameworks and ethical theory and develop recommendations from the lessons evidenced, the second main objective of our article.
This analysis advances the dialog on academic plagiarism by exploring the role of the publisher from a deontological perspective
of ethical absolutism. 相似文献
