Moral issues such as abortion, immigration, and gun rights are subject to constant debate. Yet such discussions are increasingly unproductive, perhaps because we enter such debates with closed, rather than open mindsets, which might rigidify our views, leading to perceptions of an objectively ‘correct’ answer to moral issues. This study tested whether different modes of interaction led to differences in levels of this ‘objectivist’ thought. The study also tested whether and whether threat, experienced in anticipation of a contentious interaction, mediated this effect. Participants were randomly assigned to conditions in which they received instructions on how they should approach an upcoming interaction on the topic of abortion. Instruction conditions included: competition, cooperation, persuasion, learning, neutral control, and no-opposition control (except for no-opposition control, all conditions specified that the other person disagreed with the participant on abortion). Although hypothesized group differences were not found, hypothesized mediation analyses were significant, such that competition, cooperation, and neutral control conditions produced increased threat for participants, while learning, persuasion, and no opposition control conditions produced reduced threat. Threat level positively predicted moral objectivity level for both abortion (the topic of discussion) and other moral issues. These results provide insight into why debating morally contentious issues can seem futile at best, and provides a glimpse of why this does not have to be the case.

Pricing in the market is the most sensitive part of trade. It is through pricing where the buyers are able to acquire goods and it is through it also that the sellers get their profit. Pricing of commodities can be said to be the lifeline of trade and also the lifeline of competition. Competition law, in addition to other factors such as quality of goods and their availability, also deal with the issue of pricing of goods. It is touted that competition law has a strong inclination to supervise pricing of commodities and how the conduct of market players influence pricing of goods. Competition law does this by making the market as competitive as possible in order to prevent any firm from dictating prices. It short, it strives to make the firms in the market to be price takers and not price setters as a way of reigning in on high prices in the market. However, in certain circumstances the competition laws become unable to supervise the market. In times such as those, the governments have been forced to intervene through other laws and policies in order to protect the market from possible abuse. This study looked at government intervention in the market through price control legislation. Price control legislation is a legislation that gives the government powers to artificially set prices of commodities. This is done in those dire circumstances where the market out of unforeseeable circumstances, is unable to be competitive. Examples of such instances include national crises, innovations and legal huddles. Price control legislations unlike the traditional competition laws are not created to promote competition per se. They are created on the back of competitive conduct to provide a safety net to consumers from exploitative activities of producers in instances where the influence of competition laws is ineffective. Price control legislations are there to make sure that when all competition laws and interventions are unable to protect consumers from the condition of the market and the exploitative actions of the producers, then there are certain laws created as a safety net to the consumers. Price control is used to mitigate the circumstances that make it impossible for the market through competition to control pricing of commodities. Currently, price control is becoming a prevalent way oftarning prices in many jurisdictions. A policy used in the medieval times in simple markets, with little or no inclination towards the market, has now become more imposing even in the most sophisticated markets. Price controls in areas like Canada and the European Union are being used together with competition laws to cater for areas where the governments feel that the market is not competitive enough and competition laws are not effective. In other areas such as Zimbabwe, it is being abused for political purposes to influence prices against a competitive market and the competition laws. What is clear and true is that price control having both an immediate impact and being effective, is one mechanism that has far reaching and substantial effects on the competitiveness in the market. With its target being the most sensitive area of trade, this makes it a very important policy issue that competition lawyers should not ignore. Price control ability of superseding the market mechanism of supply and demand, to impose prices and the way it is implemented gives it the power to reduce and even kill competition in a particular market. That is why it is imperative to understand this safety net as competition lawyers in order to know whether it is needed and if so how we can limit its negative effects in the market.

Belowground competition presents a threat to the production and sustainability of tree-grass ecosystems. Management scenarios designed to optimize the spatial and temporal distribution of soil resources will improve resource-use efficiency and promote greater co-production. We conducted three experiments to assess competition dynamics between loblolly pine and switchgrass. In a three-year field trial, loblolly pine and switchgrass were intercropped across varying competitive intensities. Interspecific competition decreased loblolly pine annual growth; however, establishing vegetation exclusion zones surrounding pines largely mitigated these effects. Switchgrass yields were less affected by interspecific competition compared to pines and land equivalency ratios indicated that with proper management co-production yields may exceed those of switchgrass monoculture. Switchgrass was a constant and significant competitor across all years while loblolly pine resource use was minimal in year 1 but increased in subsequent years. In a short-term greenhouse experiment, native soil was amended with biochar and inorganic N fertilizer and the effects of these amendments upon soil properties and switchgrass productivity were assessed. Biochar increased soil pH, total soil carbon, and soil moisture. However, N fertilization had negligible effects upon soil properties. Plant response to biochar was neutral to negative while N fertilization increased switchgrass foliar biomass but no interactive effects of the amendments were observed. Although the effects of biochar upon switchgrass production were trivial, its positive influence upon soil properties suggests a potential for mitigating competitive interactions. Finally, a field-scale study examined co-production of loblolly pine and switchgrass over two years in response to competition control, biochar, and N fertilizer. As expected, interspecific competition reduced soil resources and decreased plant productivity. Biochar increased total soil C and soil moisture levels but had relatively minor impacts upon other aspects of soil fertility or plant production. Nitrogen fertilization acidified soil pH and decreased total soil C and N but positively affected loblolly pine foliar N concentrations and switchgrass yields. A positive association between soil inorganic N and switchgrass yield suggests the species competitive influence may be increased with greater N supply.

Proponents of educational reform often call for policies to increase competition between schools. It is argued that market forces naturally lead to greater efficiencies, including improved student learning, when schools face competition. In many parts of the country, public schools experience significant competition from private schools; however, the literature is not clear as to whether public versus private competition generates significant improvements in technical efficiency. A major hurdle for researchers examining this issue is determining a workable definition of competition by which they can measure the degree of competition within local markets. I address this challenge by developing a School Competition Index (SCI) for Mississippi through implementation of several Geographical Information System (GIS) tools. The SCI reveals the degree of competition for each public school based on their spatial location relative to peer private schools operating within their service area. GIS is a unique way to measure the degree of competition among public schools and private schools. Including components of market structure is not sufficient to measure the effects of competition in a market; market characteristics, which vary between locations, are also important. Market characteristics such as, religiosity, school location, and social capital are used in this dissertation as exogenous variables. Two stage stochastic frontier analysis and single equation stochastic frontier analysis are both employed to evaluate school efficiency. This dissertation finds that higher degrees of competition from private schools significantly increase public elementary school efficiency, as measured by the proficiency rates in different examinations. At the same time, competition from private schools does not improve public high schools efficiency. The results suggest that a rural-urban student academic achievement gap persists, and that community social capital stock is also important to some extent. Regardless of model or estimation procedure, students’ race and socio-economic status significantly reduce public school efficiency. It is anticipated that the current results will inform policymakers regarding the viability of competition-based reforms after considering all these factors.

The price pass-through relationship of retail gasoline markets in the United States has been examined on several levels. This dissertation takes two unique approaches to examine the pass-through behavior (1) a seemingly unrelated regressions model to survey regional differences in gasoline markets and (2) a pooled panel error-correction approach to analyze the effects of spatial competition on local Mississippi gasoline markets. The first model showed the presence of rockets and feathers on a regional level in the US. Moreover, every PADD had a long run asymmetric price pass-through relationship. I included variables to capture the effect of Hurricane Katrina. The inclusion of the Katrina variable indicated only the immediate period after the storm changed the pass-through behavior. Additionally, the market returned to the pre-Katrina pass-through relationship twelve weeks after the storm. The pooled panel model showed the presence of rockets and feathers in the state of Mississippi. It also indicated that the presence of spatial competition does have an effect on the price pass-through behavior. Moreover, the exact distance to the closest competitor did have a significant effect on the price pass-through relationship.
