The dissertation research will comprise three essays on the topic of the resource curse hypothesis and its mechanisms. The phenomenon of low economic growth in resource-rich regions is recognized as the “resource curse”. These essays will contribute to an understanding of the regional resource-growth relation within a nation. Essay one tests the resource curse hypothesis at the U.S. state level. With a system of equations model, I decompose the overall resource effect to account for the two leading explanations — crowding-out and institution effects, thus investigate whether the institutions mediate the crowding-out effects. I did not find evidence of an overall negative effect on growth by resource wealth. Both the crowding-out and institution appear present, but they offset: the resource boom crowds out industrial investments, but good institutions mitigate the overall effect. Resources do reduce growth in states with low-quality institutions, including Louisiana, Oklahoma, and Texas. Essay two compares the effects of resource revenues on the economic growth and growth-related factors across Chinese provinces and American states, using panel data from 1990 to 2015. With the Instrumental Variable (IV) strategy, I show that regions with higher resource revenues grow faster than other regions in both China and the U.S. The positive resource effect is larger and more statistically significant in the U.S. Further testing impacts of three resource-related policies in China, e.g. the market price reform, the fiscal reform, and the Western Development Strategy, I show that the market price reform together with the privatization process on coal resources contribute the positive resource effect in China. Though strong and positive resource – growth relations appear in both countries, evidence also suggests consistent negative resource effects on certain growth-related factors in both countries, such as educational attainments and R&D activities. Essay three explores the schooling response to the oil and gas boom, taking advantage of timing and spatial variation in oil and gas well drilling activities. Development of cost-reducing technologies at the time of higher crude oil and natural gas prices in the early 2000s has accelerated shale oil and gas extraction in the United States. I show that intensive drilling activities have decreased grade 11 and 12 enrollment over the 14 year study window − approximately 36 fewer students per county on average and overall, 41,760 fewer students across the 15 states enrolled considered in the analysis. On average, with one additional oil or gas well drilled per thousand initial laborers, grade 11 and 12 enrollment would decrease 0.24 percent at the county level, all else equal. I investigate heterogeneous effects and show that the implied effect of the boom is larger in states with a younger compulsory schooling age requirement (16 years of age instead of 17 or 18), lower state-level effective tax rate on oil and gas productions, traditional mining, non-metro, and persistent poverty counties.

L'objectif de cette thèse a été de comprendre le fonctionnement économique des pêcheries et de proposer des politiques de gestion des ressources halieutiques. L'attention a été portée essentiellement sur la pêcherie crevettière guyanaise. Une première analyse a été effectuée à partir d'une base de données historique. Les premiers constats ont été que cette pêcherie a été marquée par une forte diminution de son stock, de son effort, de sa production, ce qui a conduit à la fermeture de certaines entreprises. Les premiers résultats ont permis de comprendre que la production de cette pêcherie est fortement dépendante du stock et que la forte diminution de ce dernier n'est pas liée à la surpêche. En effet, malgré une baisse considérable de l'effort de pêche et du prélèvement, le stock a continué de s'effondrer, suggérant ainsi que d'autres facteurs peuvent être mis en cause. En particulier, la zone de pêche est caractérisée par un environnement amazonien avec une mangrove importante et de nombreux cours d'eau. L'intégration de la mangrove dans l'analyse, qui a pourtant connu une diminution de sa surface dans les années 90, n'a pas permis d'expliquer l'effondrement du stock observé. Cependant l'intégration d'autres facteurs comme le débit des fleuves et la température de surface de l'océan ont permis de mieux comprendre la chute du stock dans cette filière. La pêcherie crevettière guyanaise semble en effet fortement impactée par le changement global, notamment l'augmentation de la température des eaux dans les zones de prélèvement. De surcroît, le dernier chapitre suggère que certains phénomènes endogènes à la pêcherie, comme les effets de congestion entre les navires de pêche, rendent l'ensemble de la pêcherie plus sensible à des chocs exogènes technologiques, économiques ou biologiques, en amplifiant l'impact de ces derniers sur les décisions optimales des entreprises concernant l'effort de pêche. Afin de préserver la pêcherie crevettière en Guyane française, il apparaît donc essentiel d'essayer de limiter, dans la mesure du possible, les sources du changement climatique, au lieu de modifier profondément les pratiques économiques du secteur. / The objective of this thesis was to understand the economic behavior of fisheries and to propose resource management policies. The focus was mainly on the French Guiana shrimp fishery. First an initial analysis will be performed on a historical data basis. Initial findings have showed that this fishery was characterized by a strong decrease in its stock, its effort, its production and lead to the closure of some companies. The results have helped also to understand that the production in this fishery is highly dependent on stock and the decrease of the stock is not related to overfishing. Indeed, despite a considerable decline in fishing effort and production, the stock continued to slump suggesting that other factors may be involved. In particular the fishing zone is characterized by an Amazonian environment with significant mangrove and many rivers. The integration of mangrove in the analysis, which shows a decrease in its surface in the 90s did not explain the collapse of the stock. However, the integration of other factors such as rivers and sea surface temperatures have increased understanding of stock depletion in this sector. The French Guiana shrimp fishery is highly influenced by global change, notably increasing in temperature. Moreover, the last chapter suggests that some endogenous phenomena in the fishery, like the congestion effects between fishing vessels, make the whole fishery more sensitive to technology, exogenous economic or biological shocks, amplifying their impact on the optimal business decisions regarding fishing effort. In order to save the French Guiana shrimp fishery, it appears therefore crucial to try to limit the sources of climate change instead of deeply modifying economic practices in this sector, which may lead to misunderstandings by fishermen and local political conflicts.

The purpose of this study was to evaluate tourism capacity, the effectiveness of the management plan and the visitors’ willingness to pay (WTP) for increased conservation effort in the Buccoo Reef Marine Park (BRMP) in Tobago. Non-market contingent valuation was applied to estimate tourists’ WTP, using the data from a survey of 164 tourists. Local residents and government agencies were consulted to evaluate the management plan and the tourism capacity. Eighty-eight percent of local residents stated that the park was not well managed and that they lacked trust in the park agency. The density of tourists was 67-97% more than socially acceptable crowding norm. The tourists were willing to pay an additional entry fee of US$11.72 per person, which would generate additional revenue for the park management. In conclusion, the BRMP management needs modification in order to increase stakeholders’ trust, reduce tourists crowding intensity, and generate additional user-based revenue.

This thesis explores Pioneer Valley farmers and their agricultural practices, knowledge and resources as they relate to climate change. Adaptive capacity is used throughout scientific literature, and often includes numerous components; for this thesis the measurement of farmers’ adaptive capacity would be assessed according to only three components: knowledge, past experiences and use of resources. Climate change and its impacts on agriculture have been studied but what is unclear is how prepared farmers are to deal with these impacts. Through literature review, survey development and recorded interviews, data was then analyzed both for quantitative and qualitative results to understand farmer’s adaptive capacity. Most Pioneer Valley farmers realized changes to their farming practices over 5 to 10 years but were not in consensus of the cause and if this could just be due to climate change. Despite belief in climate change, most were willing to accept assistance to climate change adaptation, even if not knowing what these adaptation strategies would include. As a pilot study, numerous considerations have been included for future work on this topic to reduce assumptions and improve results accuracy. The study was too small to translate to the greater Pioneer Valley for results, but the method is important and applicable in future research and should be examined further to maintain the integrity of the agriculture sector.

As the demand for freshwater resources increases due to increasing human populations, degradation of available resources, and climatic changes it will become increasingly important to understand the factors that impact the physicochemical characteristics of surface water resources over space and time. This study assessed a headwater stream over the course of a year in the San Bernardino National Forest that serves as both surface and groundwater resources for the Santa Ana River Watershed region, the largest and most populated watershed in Southern California. Streams were monitored bi-weekly during dry periods and weekly during wet periods from April 2018 through April 2019 for dissolved oxygen (DO), flow rate, temperature, conductivity, turbidity, pH, nitrate (NO3-), and ammonium (NH4+) with additional lab assessments for total dissolved solids (TDS), E. Coli (EC), and total coliform (TC). Findings illustrated that across the study sites NO3-, NH4+, and TDS exceeded federal and regional water quality standards for a majority of the sampling events (>60 percent). Additionally, NO3-, DO, and flow rates were elevated in the wet season, while conductivity, NH4+, TDS, pH, TC, and EC were elevated during the dry season.

This dissertation consists of three essays addressing different topics in health economics. In the first essay, we perform a systematic review of peer-reviewed articles examining consumer preference for the main electronic cigarette (e-cigarette) attributes namely flavor, nicotine strength, and type. The search resulted in a pool of 12,933 articles; 66 articles met the inclusion criteria for this review. Current literature suggests consumers preferred flavored e-cigarettes, and such preference varies with age groups and smoking status. Consumer preference for nicotine strength and types depend on smoking status, e-cigarette use history, and gender. Adolescents consider flavor the most important factor trying e-cigarettes and were more likely to initiate vaping through flavored e-cigarettes. Young adults prefer sweet, menthol, and cherry flavors, while non-smokers, in particular, prefer coffee and menthol flavors. Adults in general also prefer sweet flavors (though smokers like tobacco flavor the most) and dislike flavors that elicit bitterness or harshness. Non-smokers and inexperienced e-cigarettes users tend to prefer no nicotine or low nicotine e-cigarettes while smokers and experienced e-cigarettes users prefer medium and high nicotine e-cigarettes. Weak evidence exists regarding a positive interaction between menthol flavor and nicotine strength. In the second essay, we investigate U.S. adult consumer preference for three key e-cigarette attributes––flavor, nicotine strength, and type––by applying a discrete choice model to the Nielsen scanner data (Consumer Panel data combined with retail data) for 2013 through 2017, generating novel findings as well as complementing the large literature on the topic using focus groups, surveys, and experiments. We found that (adult) vapers prefer tobacco flavor, medium nicotine strength, and disposables, and such preference can vary over cigarette smoking status, purchase frequency, gender, race, and age. In particular, smokers prefer tobacco flavor, non-smokers or female vapers prefer medium strength, and infrequent vapers prefer disposables. Vapers also display loyalty (inertia) to e-cigarette brands, flavor, and nicotine strength. One key policy implication is that a flavor ban will likely have a relatively larger impact on adolescents and young adults than adults. The third essay employs a machine learning algorithm, particularly a random forest, to identify the importance of BMI information during kindergarten on predicting children most likely to be obese by the 4th grade. We use the Arkansas BMI screening program dataset. The potential value of BMI information during early childhood to predict the likelihood of obesity later in life is one of the main benefits of a BMI screening program. This study identifies the value of this information by comparing the results of two random forests trained with and without kindergarten BMI information to assess the ability of BMI screening to improve a predictive model beyond personal, demographic, and socioeconomic measures that are typically used to identify children at high risk of excess weight gain. The BMI z-score from kindergarten is the most important variable and increases the accuracy of the prediction by 14%. The ability of BMI screening programs to identify children at greatest risk of becoming obese is an important but neglected dimension that should be used in evaluating the overall utility. In the last essay, we use Nielson retail scanner dataset and apply a difference-in-differences (DID) approach and synthetic control method, and we test whether consumers in Utah reduced beef purchases after the 2009 Salmonella outbreak of ground beef products. The result of DID approach indicates that the Salmonella event reduced ground beef purchases in Utah by 17% in four weeks after the recall. Price elasticity of demand is also estimated to be -2.04; therefore, the reduction in ground beef purchases as a result of recall is comparable to almost 8.3% increase in the price of this product. Using the synthetic control method that allows us to use all of the control states to produce synthetic Utah, we found the effect of this event minimal compared to the DID effect.

One of the more important economic activities in the Altiplano region is raising livestock, the exploitation of cattle, sheep, and llamas which are raised and adapted to the conditions surrounding this activity. Livestock production plays a fundamental role in the economy of farming families by providing them products such as meat, milk, cheese, fiber, skins, and other products that each translate into monetary revenues. The present study was carried out in the community of "Chama 6 de julio," Ingavi Province, Department of La Paz, about 83 km. (51.6 miles) outside of La Paz at an elevation of 3,792 m. (12,440 ft.) above sea level. The annual precipitation is 370 mm. (14.6 inches) and average annual temperature is 12° C (53.6° F). The set objectives of this investigative work were: To evaluate the economic behavior of the livestock production (cattle, sheep, and llamas) at the small ranchers 14 level. To quantify in monetary units the structure of costs and revenues of livestock activity. To carry out a socio-economic analysis of the activity. The statistic parameters used were: measures of means, deviations, and percentages. Techniques used for gathering information include the following: semi-structured interviews, dynamic polls, dialogues, conversations, key informants, and direct observation. In studying the costs and revenues of livestock activity the conventional model of fixed and variable costs was used. The method utilized to evaluate the activity is an adaptation of the economic evaluation expressed by the indicating gauges Cost-Benefit Relationship (RBC) and Annual Investment Profitability (RI). 42 families dedicated to agricultural and livestock activity were involved in the study. They were functionally classified according to the number of cattle that they have on their land, a classification that resulted in four groups. The first group contained families possessing from 4 to 6 cattle; the second, from 7 to 9; the third, from 10 to 12; and the fourth, the families with 13 to 15 cattle. Also, the number of samples for each class was calculated to be 5 families. As livestock activity is the most important for families in this community, these families have most of their money invested in their herds, investments ranging from 73% to 86% of all their active livestock investments. The other 14% to 27% of their investment is in the livestock infrastructure, tools, materials, and equipment. The amount of land possessed by families in this community ranges from 8 to 40 hectacres (19.8 to 98.8 acres). The meat (cattle, sheep, and llama) is the most important product for commercial purposes. Accordingly, families from class IV achieved the highest production with 812 kg. (180.7 lbs) per year, followed by classes III and II. The lowest annual amount came from families grouped into class I with only 235 kg. (518 lbs). Another product of utmost importance after meat is cheese for which the families of class IV were those that had the highest annual production with 476 units, with an average weight of 0.6 kg (1.3 lbs). They were followed by families in classes III and I. Finally, the families in class II achieved the smallest output with 337 units. 69% to 79% of the total production of meat and cheese is destined for market. The families consume only 10% to 31% of what is produced. Variable costs represent 87.25% of the total expenses. On the other hand, fixed costs amount to only 12.73% of the total. Labor represents the greatest expense, reaching an average of 71.17% of the total expense. Relative to gross annual revenue, families in class IV reached the highest average numbers with 7,996.00 Bs. (Bolivianos). The lowest gross annual revenues correspond to those in class I with only 3,124.00 Bs. Classes III and II occupy intermediate positions between both former classes. Comparing the sources of gross annual revenue, cattle meat occupies the greatest portion with 40.81%. This is followed by cheese production, lamb, and llama meat with 30.84%, 23.30%, and 2.17% respectively. At the same time, cattle meat and cheese provide these farming families with 71.65% of their total gross annual revenue. The net annual revenues are positive only for families in classes IV and III with numbers at 312.00 and 156.00 Bs. On the other hand, classes II and I have negative net revenues at -3,039.00 and -2,455.00 Bs. The indicative Cost-Benefit Relationship (RBC) shows viability of the activity for families from classes IV and III with figures of 1.04 and 1.02. It is not as viable for families in classes II and I with numbers at 0.62 and 0.50. Estimates provided by the annual investment profitability (RI) are only satisfactory for those in classes IV and III with percentages of 4.6% and 2.13%. Unsatisfactory percentages result for classes II and I with -35.45% and -49.31%. According to the results obtained for the four classes, livestock activity carried out by farming families does not provide an acceptable profitability, even for families that have greater numbers of livestock (more than 12 cattle). It would be much less profitable for the families that have smaller herds of livestock.

Comprehensive planning for regional food systems is a relatively new focus in the planning field. Heightened national awareness of the economic, environmental and equity implications of our current food system has magnified the importance of planning engagement on food-system issues. While addressing food system concepts is relatively new to planners, community-based organizations have been historic players in the development of food-system programs and critical food-system policy, particularly with regard to food access and local food production. This thesis reviews the status of the regional food system in the Pioneer Valley of Western Massachusetts through an assessment of the efforts of food-related community-based organizations working in the region. The data results provide a knowledge platform for the regional planning agency that supports collaboration with community-based organizations, builds upon current assets and opportunities for improvement, and facilitates strategies to address food-system barriers, in order to develop and sustain a viable food system for the Pioneer Valley region. This research intends to support two central conceptual objectives: first, providing evidence to support the key role of planning practice in food-system efforts; and second, highlighting the importance of planning and community-organization collaborations to achieve greater systemic impact. Finally, this research aims to expand available information regarding the role of collaborative planning and community organization partnerships in the food-system change process, so as to highlight assets and strengthen the integration of efforts towards building comprehensive and sustainable regional food system networks.

This research investigates the use of pro-social emotions to improve cooperation. In particular, it tries to reconcile the results from Noussair and Tucker (2007) and Lopez et al. (2010). To reach this goal the experiment considers different degrees of revelation: no revelation, partial and full disclosure of information. Additionally, I use different microeconometric specifications to accommodate different hypothesis about the motivation of the subjects. My results diverge from those of Lopez et al. because I find that revealing the decision of a single subject at random does not significantly increase cooperation, which is the main result of these authors. Also, my findings indicate that cooperation is triggered only when I reveal information of either 3 or all the subjects in the group, the last case being similar to the public observability of Noussair and Tucker. These authors find a non-permanent increase in contributions, so I do but using a positive framed-experiment with disclosure of additional information, the group’s earning loss. Therefore, random revelation together with the disclosure of information about subjects’ decisions appears to be a good alternative to promote cooperation in a sample pool of undergraduate students. Also, I observe a reduction in contributions over time, but in the random revelation treatment this decay by less than 40%. The most interesting result that I obtain is the evidence of altruism and positive reciprocity in the specification of Ashley et al. (2003, 2010), instead of the matching in contributions reported by these authors.

This study aims to review thirteen coastal restoration projects considering the various ecosystem services provided by restoration and estimates the economic value of one of the ecosystem services of restoration. These ecosystem services include water quality improvement, fish and benthic species productivity, shoreline stabilization, oyster abundance, and marsh growth. The projects represent a set of large-scale projects within Alabama and Mississippi, with construction and monitoring costs ranging from $2.3 million to $50 million per project. To determine the economic value of one of the ecosystem services of coastal restoration projects, I used the meta-analysis method to estimate the willingness to pay (WTP) for coastal water quality improvements. The estimated function from the meta-analysis is applied to parameters specific to the study area. The WTP for improved coastal water quality, from a baseline of fishable but likely to degrade, to an improved fishing catch rate, is $203 per household annually among residents of Alabama and Mississippi.
