Bayesian Unconditional Quantile Regression: An Analysis of Recent Expansions in Wage Structure and Earnings Inequality in the US 1992–2009

We develop Bayesian inference for an unconditional quantile regression model. Our approach provides better estimates in the upper tail of the wage distribution as well as valid small sample confidence intervals for the Oaxaca–Blinder decomposition. We analyze the recent changes in the US wage structure using data from the CPS Outgoing Rotation Group from 1992 to 2009. We find that the largest part of the recent changes is explained mainly by differences in returns to education while the decline in the unionization rate has a small impact, and that earnings inequality is rising more at the top end of the wage distribution.     

Course Allocation via Stable Matching

The allocation of students to courses is a wide-spread and repeated task in higher education, often accomplished by a simple first-come first-served (FCFS) procedure. FCFS is neither stable nor strategy-proof, however. The Nobel Prize in Economic Sciences was awarded to Al Roth and Lloyd Shapley for their work on the theory of stable allocations. This theory was influential in many areas, but found surprisingly little application in course allocation as of yet. In this paper, different approaches for course allocation with a focus on appropriate stable matching mechanisms are surveyed. Two such mechanisms are discussed in more detail, the Gale-Shapley student optimal stable mechanism (SOSM) and the efficiency adjusted deferred acceptance mechanism (EADAM). EADAM can be seen as a fundamental recent contribution which recovers efficiency losses from SOSM at the expense of strategy-proofness. In addition to these two important mechanisms, a survey of recent extensions with respect to the assignment of schedules of courses rather than individual courses is provided. The survey of the theoretical literature is complemented with results of a field experiment, which help understand the benefits of stable matching mechanisms in course allocation applications.     

Development banking and technological development: a case study of industrial development banks in the GCC countries

This article explores the important role of Industrial Development Banks in promoting the quality of technological development. It is argued that the historical experiences of the developed economies and several developing economies during recent times support the need and potentials of a more pro-active role by Industrial Development Banks. Against this background, the specific experiences of Industrial Development Banks in the Gulf Co-operation Council Countries are examined and the results of a select field survey are reported. This exploratory study suggests that some fundamental steps are needed in order to develop Industrial Development Banks from being comparatively passive conduits of technological aid to more active promoters of technological development.     

Estimating the Impact of WTO and Domestic Reforms on the Indian Cotton and Textile Sectors: a General-Equilibrium Approach

The agreement to abolish the quotas on textiles and clothing introduced under the Multi‐fiber Arrangement (MFA) will create a new and much more competitive world market for India's exports of textiles and clothing. India's inefficient and costly policies, such as cotton export quotas, the hank yarn obligation, and the restrictive policies on foreign investment that have held back productivity in the Indian apparel sector, will impose serious costs. The authors consider the implications of reforming these policies in an open trading environment using a multiregion, applied general‐equilibrium model. They find that the costs of these policies to India increase substantially following abolition of the MFA; the benefits to India from domestic reforms are considerably enhanced when there is global free trade in textiles and apparel.     

Blockchain for tracking serial numbers in money exchanges

Money exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership transfers. The approach was tested with a total of 110 banknotes of different currency types and achieved an average accuracy of 91.17%. We conducted a user study in real‐time with 21 users, and the mean accuracy across all users was 86.42%. Each user gave us feedback on the proposed approach, and most of them welcomed the idea.     

May business mentors act as opportunity brokers and enablers among university students?

Networks are recognized as a central component of the entrepreneurial process, in particular with regard to opportunity identification and exploitation. In this study, we specifically analyze the role of mentors who are in business as opportunity brokers and enablers among university students with entrepreneurial intentions. Our investigation on 1022 students from 13 French-language universities based in Canada, France, Belgium and Algeria indicates that mentors in business, contrary to other mentors, support opportunity identification and exploitation among university students. Although student gender, entrepreneurial experience and education have a more pronounced effect, mentoring is the only element that can be controlled for through the creation of formal support programs. These results call on public authorities, and universities in particular, to implement formal mentoring programs to support students who are interested in starting their own business, and who would not otherwise have access to business mentors in their environment.     

WHY DO CHILDREN TAKE CARE OF THEIR ELDERLY PARENTS? ARE THE JAPANESE ANY DIFFERENT?

We conduct a theoretical and empirical analysis of why children live with (or near) their parents and provide care and assistance to them using microdata from a Japanese household survey, the Osaka University Preference Parameter Study. We find that the Japanese are more likely to live with (or near) their elderly parents and/or to provide care and attention to them if they expect to receive a bequest from them, which constitutes strong support for the strategic bequest motive, but that their caregiving behavior is also heavily influenced by the strength of their altruism toward their parents and social norms.     

Enhancing the teaching of introductory economics with a team-based,multi-section competition

The authors describe a unique approach to enhancing student learning at the introductory economics level that utilizes a multi-section, team-based competition. The competition is structured to supplement learning throughout the entire introductory course. Student teams are presented with current economic issues, trends, or events, and use economic tools and theories to comprehensively examine the topics. Students present their analyses in their own sections with one team from each section moving on to compete in an inter-section round. Students are judged on technicality, creativity, and applicability of economic concepts. The competition has the potential to advance students' creativity, collaboration, communication, and critical and analytical thinking skills, while enhancing their ability to apply foundational economic concepts to real-world settings.
