In recent years, the issues of energy dependency and renewable energy options have gained recognition with not only policy-makers but also mainstream consumers. Understanding consumer beliefs and preferences related to these issues is therefore relevant as innovative renewable energy markets have the potential to change conventional consumer purchasing decisions. This paper investigates the beliefs and behaviors of U.S. consumers related to E85 ethanol from corn and cellulosic feedstocks. Four distinct market segments are created so that the ethanol market can be investigated more in-depth. Overall familiarity with ethanol as an alternative fuel is high; however, individual segments vary on beliefs related to corn and cellulosic ethanol, purchasing Flex-Fuel Vehicles, general concern for the environment, and many other factors. In order to successfully market ethanol to a diverse market, the preferences, beliefs and behaviors of these four distinct segments should be taken into account. While environmental concern has waxed and waned over time, issues like as climate change have come to the forefront of both domestic and international discussion and policy. The role of greenhouse gas emissions in contributing to climate change has been acknowledged. As a major source of emissions, transportation fuels are an obvious source of potential reductions in greenhouse gas emissions. This study segments consumers into four distinct market segments and uses a contingent choice method to determine willingness to pay for reductions in greenhouse gas emissions through purchases of E85 ethanol blends. Overall, willingness to pay is estimated at about 0.18 cents per gallon for each percentage in emissions reductions when compared with gasoline containing no ethanol (E0). Willingness to pay for emissions reductions varies in significance and degree across the four market segments. The diversity between the four segments implies that marketing plans should take into account the heterogeneity of consumers and make efforts to account for their varied needs and preferences.

Concerns regarding energy security, resource sustainability, and environmental protection have heightened interests in renewable fuels and sparked the research and development of ethanol as a transportation fuel. This study examines consumers’ willingness to pay for ethanol from various potential feedstocks; corn, switchgrass and wood wastes. Data was collected via a survey of fuel consumers across the United States in 2009. Results show that consumers have a preference for E85 (a fuel blend with 85 percent ethanol and 15 percent gasoline) from corn, switchgrass and wood wastes compared to E0 (gasoline) and a preference for E85 from switchgrass and wood wastes, but not corn when compared to E10 (10 percent ethanol and 90 percent gasoline). Also, consumers have a preference for E85 compared to E10 but not compared to E0. Mean WTP for E85 was insignificant across all models, but significant for all other product attributes; percentage of fuel imported, percentage of greenhouse gas emissions reduced, and the proximity of fuel in driving distance. This suggests a WTP for a combination of fuel attributes associated with ethanol rather than just for E85. Results suggest that price and proximity of the fuel have a greater impact on fuel selection than percentage of the fuel imported and reductions in greenhouse gas emissions. Republicans had a positive WTP for E85 compared to E10 and a negative WTP for E85 compared to E0 regardless of feedstock, which may suggest that Republicans actually have no preference for E85; however, these findings may also suggest that Republicans view E85 as a voluntary “policy” whereas E10 is an example of government intrusion in the free market. Thus, they may ultimately have preferences over the manner in which the blend is being introduced to the market. Across all models, those undecided in political affiliation, those previously familiar with ethanol, and those who prefer to devote U.S. farmland to food instead of fuel generally exhibited a lower WTP for E85 while Westerners, those worried about the environment, and those believe that reducing dependence on foreign oil is more important than environmental protection generally had a greater WTP for E85.

Dans la conjoncture économique actuelle un nombre croissant de firmes se trouvent confrontées à des difficultés économiques et financières qui peuvent, dans certains cas, conduire à la faillite. En principe, les difficultés ne surviennent pas brutalement, en effet, avant qu'une entreprise soit déclarée en faillite, elle est confrontée à des difficultés financières de gravité croissante : défaut de paiement d'une dette, insolvabilité temporaire, pénurie de liquidité, etc. L'identification des causes de la défaillance n'est pas évidente, puisqu'on ne saurait énumérer de manière limitative les facteurs qui la provoquent. Les causes sont multiples et leur cumul compromet d'autant plus la survie de l'entreprise. L'importance de ce phénomène et son impact sur l'ensemble de l'économie justifie le besoin de le comprendre, l'expliquer en analysant les causes et les origines. L'objectif de notre étude est de classer les entreprises en difficulté selon leur degré de viabilité et de comprendre les causes de la dégradation de leur situation. Nous effectuerons une comparaison entre trois modèles (Analyse discriminante linéaire, le modèle Logit et la régression PLS) ce qui nous permettra à partir des taux de bon classement obtenus, de choisir le meilleur modèle tout en précisant l'origine et les causes de ces défaillances.

Given the question of how to further decrease childhood mortality and attain the fourth MDG in Bangladesh, the determinants of childhood mortality and successful health intervention programmes in a rural area of Bangladesh are examined in this paper. The binominal logit regression analysis, on Matlab HDSS data from 2001 to 2005, indicates that the child’s birth order, outcome of mother’s previous pregnancy, mother’s age, mother’s education, economic condition of the household, immunization, and place of delivery are important determining factors of childhood mortality. Interview discussions show that the delivery of health services is a determining factor for successful health intervention programmes. It is worth to note that childhood mortality levels are no longer significantly lower in the treatment area of Matlab. Furthermore, the intervention programmes in the area require continuous reform, especially in the fields of birth assistance and injury prevention.

The aim of this thesis is to study the effect of smoking and drinking on wages in Sweden. The data used in this study is the Swedish Level-of-living survey (LNU) from 1991. A multinomial logit model and the marginal effects from the estimated model are used to study the effect of smoking and drinking on wages in Sweden. The empirical results conclude that medium drinking increases the probability of having a high income, i.e. there is a positive significant relationship between medium drinking and wages in Sweden. Also concluded from the empirical results is that there is not a significant relationship between smoking and wages in Sweden.

This thesis investigates the associations between crash outcomes, the existence and type of driver distraction as well as driver’s age. The crash outcomes considered in this thesis consist of the type of crash as well as the injury severity sustained by occupants involved in the crash. An ordered logit model was built to predict the likelihood of severe injuries and a multinomial model was developed to predict the likelihood that a driver will be involved in one of three common crash types: singular, angular, and rearend. In these models, various factors (e.g., weather, driver’s gender, and speeding) have been statistically controlled for, but the main focus was on the interaction of driver’s age and distraction type. The findings of this thesis have implications for policy making and prioritizing capabilities of distraction-related safety systems.

Consumers are becoming increasingly concerned about their foods and more particularly, the origin of their foods and the ingredients they contain. In light of the demand for additional origin information, the 100% Canadian milk branding initiative was launched in 2009 as a means of informing consumers about the origin of milk in their dairy products. The information is indicated by the presence of the 100% Canadian milk symbol on dairy products and can be characterized a form of co-branding. The literature on co-branding stipulates that co-branding can result in changed product perceptions either negatively or positively. In addition, the willingness to pay (WTP) literature stipulates that WTP is determined by product attributes and individuals’ characteristics. This thesis therefore seeks to ascertain the factors affecting consumers’ preferences and WTP for products with the 100% Canadian milk symbol. Specifically, the effects of individual characteristics such as health consciousness, patriotic values and risk perceptions on preferences for dairy products with the symbol are evaluated. Concurrently, the study explores the relationship between respondents’ knowledge of the Canadian dairy industry and WTP for the symbol. Data were gathered from a total of 1012 milk and ice cream consumers using two nationwide internet surveys. Estimations are carried out using the Multinomial Logit (MNL) and the Random Parameter Logit models (RPL). The results suggest that consumers in general have positive perceptions of milk and ice cream with the 100% Canadian milk symbol but negatively perceive store brand and organic labels. However, in some cases, combining a store brand label or organic label with the 100% Canadian milk symbol, are shown to alter consumers’ perceptions of the product. Some socio-demographic variables and individual characteristics were also found to be influential in intended purchase behaviours and WTP for milk and ice cream. The findings from this study provide information on consumers’ perceptions and attribute preferences and are expected therefore to contribute to the marketing strategies of the Canadian dairy industry as a whole.

This study analyzes the determinants of return migration from Sweden to Bosnia and Herzegovina, and outmigration to third country during the time period 1994-2003. The study is limited to the refugees who arrived to Sweden 1993-1994. One important aim is also to find out to what extent the propensity of return migration is affected by integration and participation in the Swedish labor market. There is a larger fraction of the refugees from Bosnia and Herzegovina who return than migrate to a third country. The results show that a higher education is affecting the return migration decision positively, but not the migration to another country. Since the social protection system in Bosnia and Herzegovina is partially undeveloped, only those with a well paid job or wealthy relatives can afford any mishaps. Highly educated individuals are expected to have these economical prerequisites. Being employed in Sweden or receiving social benefits there, give negative marginal effects on the probability of emigration. Therefore, the position on the Swedish labor market has importance for an emigration decision. Being married or having children decreases the probability of emigration. However, the family status effects are stronger for outmigration to a third country. Further, it is more likely for a family to return than emigrate to a third country. It is also more likely for women to return, while there is a larger fraction of men that migrate to a third country. Summarizing the most important findings, the probability of outmigration is strongly reduced by the level of integration. This is not only an analysis of individual micro data. The political and economic differences between home country and source country are also compared. Pull-factors seem to dominate return migration since Sweden has a more stabilized economic and political situation. However, the refugees must have strong economic prerequisites or wealthy relatives to support them, in order to realize a return migration decision. A large fraction of the refugees who wish to return do not have the possibilities to realize their return intentions. They consider themselves as temporary migrants, but have involuntary become permanent migrants in Sweden.
