A new and direct test of the ‘gender bias’ in multiple-choice questions

Local and international research has identified a bias in favour of male students with MCQs. If correctly identified, this bias holds implications for reasonable assessment strategies in economics courses. A standard method used in the literature is to relate student performance to various features of the learning environment (such as the type of question) and to student-specific characteristics (such as past performance and lecture attendance). A more direct approach is possible: we set comparable questions (in three categories – graphs, quantitative and theory) in the written and MCQ sections of three tests in the introductory microeconomics course at the University of Stellenbosch. This allows a direct comparison between the performance of male and female students (overall and per question category), without the need to model overall student performance. The number of students in this course, almost 2000, offers a suitably large sample for studying this question. Our evidence does not confirm the strong claims about gender bias in the literature; indeed we find the opposite: a strong positive female gender effect, but for written questions only. We also find no evidence of higher risk-aversion by female students towards MCQ questions with negative marking.Gender bias, Economics education

The conflict resolution styles and relationship satisfaction of couples living in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University

Communication forms an integral part of couple interactions and managing conflictual communications competently greatly contributes to the quality of a relationship. This study was a partial replication of Vito's Canadian study (1998) and was designed to investigate self-reported levels of relationship satisfaction and life satisfaction, conflict resolution styles and perceived effectiveness of problem solving in individuals in cohabiting or marital relationships. These variables were examined with self-report data from 75 participants (61 women and 14 men) who participated in a mail survey. The measures used to examine these variables of interest included the Kansas Marital Satisfaction Scale, Conflict Resolution Styles Inventory, Life-as-a-whole Index and a subscale of the Couple Problem-Solving Scale which measured the perceived effectiveness of personal and partner problem solving. Correlational calculations and hierarchical multiple regression analyses demonstrated that conflict resolution styles accounted for a significant amount of variance in relationship satisfaction. In particular it was found that the conflict resolution style of positive problem solving was positively related to relationship satisfaction. Individuals who, however, reported higher levels of the so-called "negative" conflict resolution styles of conflict engagement, withdrawal and compliance obtained concurrent lower scores on relationship satisfaction. Further data analyses indicated that self-reported levels of relationship satisfaction were positively related to life-as-a-whole satisfaction. Self-reported levels of perceived effectiveness of personal and partner problem solving ability were also found to be positively related to relationship satisfaction. These preceding relationships were maintained once additional factors such as duration of relationship and other demographic variables were controlled for

Happy in the service of the Company: the purchasing power of VOC salaries at the Cape in the 18th century

This paper contributes to the debate on the level and trajectory of welfare at the Cape of Good Hope during the 18th century. Recent scholarship (for example, Allen 2005) has calculated and compared the levels and evolution of real wages in various European and Asian economies since the early modern period. To this lit-erature we add evidence for unskilled and skilled workers of the Dutch East India Company at the Cape of Good Hope during the 18th century, following De Zwart (2009; 2011), who recently presented evidence for unskilled workers in the Cape for the latter half of the 17th century and the 18th century. We calculate job-specific real wages in a three-step argument; from the narrowest international comparison of wage rates in terms of silver content to one based on a basket of widely consumed goods. The paper’s contributions lie in the breadth of the com-parisons, the inclusion of skilled workers in the comparison and the adaptation of the consumption basket to local conditions and relative prices at the Cape. The results support the hypothesis that at the start of the 18th century, the Cape Col-ony was relatively poor on an international comparison, but as the century un-folded, gained considerably on even the richest contemporary societies.Real wages, Dutch East India Company (VOC), Cape Colony, Compari-sons of living standards, Economic history of South Africa, Economic history of the Cape Colony

Trends in Non-Farm Self-Employment Activity for Rural Women 1981-2001

The importance of non-farm self-employment activity as a source of employment and income in Canada's rural and small town (RST) labour market is increasing. This paper provides an overview of major trends in non-farm self-employment activity for rural women, compared to urban women and rural men. In 2001, 14 percent of female workers in the RST labour market were engaged in nonfarm self-employment activity, compared to 9 percent in 1981. Women in RST areas were more likely to have some non-farm self-employment activity, compared to women in larger urban centres (LUC). In each rural / urban group, women, ages 50 to 64, were more likely to report some non-farm self-employment activity than younger women. Women's non-farm self-employment activity rates are lower than men's in each rural / urban group nationally. However, the gap between women's and men's rates is decreasing. Women in RST areas are less likely to earn $20,000 or more from (unincorporated) nonfarm self-employment activity, compared to women in LUC areas. Regardless of type of geographic area, women with (unincorporated) non-farm self-employment income are less likely than men to earn$20,000 or more from this source.Labor and Human Capital,

The miracle of the Septuagint and the promise of data mining in economics

This paper argues that the sometimes-conflicting results of a modern revisionist literature on data mining in econometrics reflect different approaches to solving the central problem of model uncertainty in a science of non-experimental data. The literature has entered an exciting phase with theoretical development, methodological reflection, considerable technological strides on the computing front and interesting empirical applications providing momentum for this branch of econometrics. The organising principle for this discussion of data mining is a philosophical spectrum that sorts the various econometric traditions according to their epistemological assumptions (about the underlying data-generating-process DGP) starting with nihilism at one end and reaching claims of encompassing the DGP at the other end; call it the DGP-spectrum. In the course of exploring this spectrum the reader will encounter various Bayesian, specific-to-general (S-G) as well general-to-specific (G-S) methods. To set the stage for this exploration the paper starts with a description of data mining, its potential risks and a short section on potential institutional safeguards to these problems.Data mining, model selection, automated model selection, general to specific modelling, extreme bounds analysis, Bayesian model selection

Business Cycles in Emerging market Economies: A New View of the Stylised Facts

This paper builds on an earlier work in business cycle theory - explicitly in the classical cycle tradition of Burns and Mitchell (1946) and the more recent work by Harding and Pagan (e.g.: 2002a; 2005b; 2005a) - to identify and analyse business cycles in emerging market economies. The goal is to revisit the work of for example Agénor, McDermott and Prasad (2000), whom have established a set of stylised facts for business cycle fluctuations in developing countries. Agénor, et. al. (2000) established these stylised facts using the presently standard method of analysing the features of serially correlated deviations from trends (idenified with statistical techniques such as the Hodrick-Prescott filter) in certain macroeconomic time series, including real GDP, the price level, and components of final demand. The alternative method, implemented in this paper, uses an algorithm of Bry and Boschan (1971), and the recent work of Harding and Pagan to identify the various stylised facts regarding the duration, steepness, amplitude and concordance of these fluctuations in emerging market economies.business cycles, turning points, emerging market economies, quantitative analysis of business cycles, time series econometrics, regression with binary variables

Higher education export service delivery by the University of Stellenbosch

International trade in higher education services provides opportunities for stimulating economic development and fostering the mobility of knowledge, leading to increased intellectual capital, which is vital for a country to remain competitive in a globalising world. The aim of this paper is to explore the nature and scope of the delivery of higher education export services at the University of Stellenbosch. To this end, a questionnaire was constructed and distributed among 109 international students at the University of Stellenbosch during 2009. This pilot study investigates the factors that motivate international students to further their studies at the University of Stellenbosch. In addition, it provides an estimate of the associated economic impact on the hosting country of exporting higher education services.Trade in Education Services, Comparative Advantage, Higher Education Services

On the (non-)equivalence of capital adequacy and monetary policy: A response to Cechetti and Kohler

The instrument problem in monetary policy is back on the agenda. Until recently interest rate policy was widely thought to be sufficient for the attainment of appropriate monetary policy goals. No longer. In the wake of the international financial crisis there is much pressure on monetary authorities to incorporate the goal of financial stability more explicitly in policy. This requires an expansion of the instruments typically used by central banks. Cechetti and Kohler (2010) recently considered this new version of the instrument problem in monetary policy by analysing the distinct role and potential for co-ordinating (i) interest rates and (ii) capital adequacy requirements. In this paper we connect this modern debate with an earlier version of the instrument problem, famously discussed by Poole (1970). Then, as now (we claim), the main message of the analysis is the non-equivalence of these instruments and the structural features of the economy on the basis of which one would prefer a particular combination of these instruments. These results are demonstrated with a set of simulations. We also offer a theoretical criticism of the modelling approach used by Cechetti and Kohler (2010).Monetary policy, Instrument problem, Interest rates, Alternative monetary policy instruments, Balance sheet operations, Policy co-ordination

An Existential Perspective on Addiction Treatment: A Logic-based therapy case study

In this essay I argue that a comprehensive understanding of addiction and its treatment should include an existential perspective. I provide a brief overview of an existential perspective of addiction and recovery, which will contextualize the remainder of the essay. I then present a case study of how the six-step philosophical practice method of Logic-Based Therapy can assist with issues that often arise in addiction treatment framed through an existential perspective
