The inflation and inflation uncertainty relationship for Turkey: a dynamic framework

This article assesses the interaction between inflation and inflation uncertainty in a dynamic framework for Turkey by using monthly data for the time period 1984–2009. The bulk of previous studies investigating the link between inflation and inflation uncertainty employ Autoregressive Conditional Heteroskedasticity (ARCH)-type models, which consider inflation uncertainty as a predetermined function of innovations to inflation specification. The stochastic volatility in mean (SVM) models that we use allow for gathering innovations to inflation uncertainty and assess the effect of inflation volatility shocks on inflation over time. When we assess the interaction between inflation and its volatility, the empirical findings indicate that response of inflation to inflation volatility is positive and statistically significant. However, the response of inflation volatility to inflation is negative but not statistically significant.     

Trade Liberalization and Antidumping: Is There a Substitution Effect?

Many nations have undergone significant trade liberalization even as they have increased their use of contingent protection measures. This raises the question of whether some of the trade liberalization efforts, at times accomplished through painful reforms, have been undone through a substitution from tariffs to non‐tariff barriers. Among the new forms of protection, antidumping is the most relevant. This paper examines whether the use of antidumping is systematically influenced by the reduction of applied sectoral tariffs in a sample of 29 developing and six developed countries from 1991 through 2002. Evidence is found of a substitution effect only for a small set of heavy users of antidumping among developing countries. There is no similar statistically significant result for other developing countries or developed countries. Robust evidence is also found of retaliation and deflection effects as determinant of antidumping filings across all subsamples.     

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.
