Finance and growth in Africa: The broken link

While bank liabilities in Sub-Saharan Africa are found to follow (but not lead) economic growth, the link between bank credit and growth is altogether absent.     

The distributional impact of large dams: Evidence from cropland productivity in Africa

We examine the distributional impact of large dams on cropland productivity in Africa. As our unit of analysis we use a hydrology based spatial breakdown of the continent that allows one to exactly define regions in terms of their upstream/downstream relationship at a highly disaggregated level. We then use satellite data to derive measures of cropland productivity within these areas. Our econometric analysis shows that while regions downstream benefit from large dams, no beneficial effects accrue to cropland within the vicinity. Moreover, we find that the productivity enhancing impact of upstream dams is dependent on the local climate. Overall our results suggest that upstream dams have quantitatively on average provided up to 12% of the minimum daily per capita amount of kilocalorie needs in downstream communities and increased agricultural production by 1%.     

Rules,standards, and ethics: Relativism predicts cross-national differences in the codification of moral standards

This research examines the relationship between the code of ethics adopted by businesses in a country and the ethics positions of the inhabitants of that country. Ethics Position Theory (EPT) maintains that individuals’ personal moral philosophies influence their ethical judgments, actions, and emotions. The theory, when describing individual differences in moral philosophies, stresses two dimensions: relativism (skepticism with regards to inviolate moral principles) and idealism (concern for positive outcomes). Extending previous research that identified differences in relativism and idealism between residents of different countries and world regions, we examined the relationship between relativism, idealism, and the regulatory standards governing commercial activities of firms headquartered in Australia, Austria, Belgium, Canada, Hong Kong, Ireland, Japan, New Zealand, Spain, the UK, and the US. The results indicated that the level of relativism of a nation's populace predicted degree of ethical codification of commerce in that nation. These findings suggest that the ethical conduct of business will be more closely regulated in countries where relativism is low (e.g., Australia, Canada) but less closely regulated in countries where the residents are more ethically relativistic (e.g., Hong Kong, Spain).     

The Emergence of Individual Knowledge in a Group Setting: Mitigating Cognitive Fallacies

Research in psychology has found that subjects regularly exhibit a conjunction fallacy in probability judgments. Additional research has led to the finding of other fallacies in probability judgment, including disjunction and conditional fallacies. Such analyses of judgments are critical because of the substantial amount of probability judgment done in accounting, business and organizational settings. However, most previous research has been conducted in the environment of a single decision maker. Since business and other organizational environments also employ groups, it is important to determine the impact of groups on such cognitive fallacies. This paper finds that groups substantially mitigate the impact of probability judgment fallacies among the sample of subjects investigated. The key finding of this paper is the analysis of the apparent manner in which groups make such decisions. A statistical analysis, based on a binomial distribution, suggests that groups investigated here did not use consensus. Instead, if any one member of the group has correct knowledge about the probability relationships, then the group uses that knowledge and does not exhibit fallacy in probability judgment. Having a computational model of the group decision making process provides a basis for developing computational models that can be used to simulate “mirror worlds” of reality or model decision making in real world settings.     

On structural inelasticity of modal substitution in freight transport

At the European level there is an increasing focus on how freight transport can be moved from trucks on roads to more environmentally friendly modes such as rail and ship. A large proportion of the transport services between OD pairs, however, cannot be substituted since there is only one alternative available. The paper investigates the magnitude of this “structural inelasticity” of modal substitution in freight transport due to a sparser layout of rail and ship-based freight networks compared to road. In the analysis we use a recent Scandinavian freight demand model covering more than 800 zones. We find that the structural inelasticity is very significant - in particular for transportation over less than 500 km. Moreover, the inelasticity varies greatly with commodity groups and between OD pairs, and it depends strongly on the port and rail infrastructure. The results suggest that pure charging instruments (road pricing for trucks) in many regions will have limited mode substitution impacts. However, if combined with structural changes in terms of improved infrastructure for rail and ship, impacts may be greater.     

“My Fifty Shoes Are All Different!” Exploring,Defining, and Characterizing Acquisitive Buying

Why does someone buy the tenth pair of black shoes or the fourteenth white t‐shirt? Typically, extreme buying is associated with negative feelings and consequences: issues of self‐control, guilt, and financial problems are common among compulsive, impulsive, excessive buying, fixated buying, and hoarding. However, through two studies, the authors describe “acquisitive buyers,” who exhibit an extreme yet controlled acquisition process for items in a chosen product category. In his/her mind, these items are minutely differentiated and enrich the inventory, and there is logical justification that every purchase enhances his/her preparedness for anticipated specific product use occasions. Materialism, positive perfectionism and variety‐seeking in a particular product category are some of the characteristics of these buyers. The studies also help distinguish acquisitive buying from other types of extreme buying and mainstream buying.     

The effect of WTO norms on the agricultural industrial complex in advancement to the new technological system: The case of Kurgan oblast

The paper considers competition advantages and search for new theoretical-methodological approaches to the most efficient way to solve the problem of development of the agricultural-industrial complex (AIC) of Russia and its regions in the context of its accession to the WTO. It shows the basic characteristics of the technological systems in the AIC and the technological level of the AIC on the case of Kurgan oblast and reveals the WTO norms able to have a negative effect on the formation of the 6^th technological system in AIC of Russia.     

Government bond market: Potential for establishing a system of primary dealers in Russia based on relevant world experience

The paper considers a potential improvement in the stability of the Russian government bond market by establishing a system of primary dealers. The existing world models of primary dealership are identified and their relations with national market peculiarities are determined based on the analysis of statistics and regulatory documents of 22 countries. The revealed regularities allow the authors to propose a private dealership model adapted to the specifics of the domestic economy.     

Discretionary fiscal policy and economic activity in Greece

This paper investigates the effects of discretionary fiscal policy changes on economic activity and its subcomponents in Greece in the period 2000–2011. Changes in government spending and net taxes have Keynesian effects. An increase in government consumption has the most pronounced positive effects on output growth, private consumption and non-residential investment, while it reduces residential investment. Cuts in the public investment programme crowd in private investment, but are associated negatively with the net exports ratio. Both indirect and direct tax hikes lower private consumption, private investment and output growth. However, higher direct taxes by lowering disposable income they reduce import demand, thus, improving the trade balance.     

EVIDENCE ON THE RELATIONSHIP BETWEEN ECONOMICS AND CRITICAL THINKING SKILLS

This research provides empirical support for the hypothesis that learning economics increases a student's critical thinking skills. Using the short form of the Watson-Glaser Critical Thinking Appraisal (WGCTA-S) as our measure of critical thinking skills, we find that students who gain a high level of economic understanding in their introductory economics class, as measured by the Test of Understanding College Economics (TUCE), have statistically significant gains in their WGCTA-S scores. Students who spend more time taking classes and are more fully engaged in the university experience also have greater gains in critical thinking. These results lend support to the idea that introductory economics courses can work in concert with other university level courses, especially within the context of a full-time curriculum, to enhance critical thinking skills.
