La llegada de ingresos provenientes de la distribución digital de la prensa continúa siendo reducida. A pesar de su volumen de lectores, el aumento de posibilidades dentro de los formatos publicitarios, la capacidad de medición del retorno de la inversión que ofrece el medio digital y la aparente unificación en la medición de audiencia que desde 2012 está presente en el mercado. De esta manera, los diferentes medios continúan sin conseguir rentabilizar la migración digital que cada día conlleva continuos gastos sin ofrecer beneficios. La audiencia como moneda de cambio en la comercialización de espacios publicitarios ha perdido todo su valor, pese al retorno de la inversión que ofrece. Este trabajo describe esta problemática y los cambios realizados antes y después del «fin del debate de la medición de audiencias» con el objetivo de poner en valor la venta de los espacios publicitarios digitales. En concreto se analiza el caso de los diarios digitales por su elevada lectura y sus escasos ingresos.

La articulación entre las políticas de empleo y las políticas sociales condicionan la percepción subjetiva de incertidumbre los individuos. El modelo de mercado laboral tiene un peso determinante en la percepción de incertidumbre. El empleo en sí mismo ya no es suficiente garantía de ingresos seguros. El empleo a tiempo parcial y los contratos temporales generan una creciente demanda de políticas de redistribución de los ingresos en los países del Sur y Este de Europa. En los países escandinavos los mismos tipos de contratos laborales generan menos desigualdad porque el empleo público contribuye a generar un “círculo virtuoso” que favorece las políticas de igualdad y la conciliación entre la vida laboral y familiar. A nivel individual las actitudes pro-redistributivas las impulsan las mujeres, aquellas personas con incertidumbre en sus ingresos económicos y con bajo nivel de estudios. Por el contrario, quienes más confían en el éxito individual y el mérito son los jóvenes con estudios universitarios y aquellos que perciben ingresos económicos altos.

This paper aims to analyse a sample of Galician co-ops to verify whether or not it is possible to deduce different financial behaviours among co-op partners from the amount of net-surplus. To this end, our study adds net-surplus to the variation registered in some account entries so that other residual incomes yielded by the co-op may be considered. The distribution of these revenues shows that partners do not usually choose to fully anticipate residual incomes. This reveals that some firms follow a positive net-surplus strategy, which is actually different from the null net-surplus strategy asserted by the classical financial theory. Furthermore, results show that differences between both strategies are statistically significant. This opens a path to future research on determinants explaining why co-op partners voluntarily renounce to anticipating these residual incomes. Such behaviour only arises when yearly accounts render a positive result, thereby making the accounting net-surplus a useful tool to analyse financial information in co-op societies.

Cette thèse examine l’investissement en capital humain au Canada en s’intéressant à la contribution de l’aide financière aux études, aux effets de la fiscalité, à la rentabilité de l’investissement en éducation postsécondaire et à la redistribution des revenus. Elle est subdivisée en cinq chapitres. Le premier chapitre présente une révue chronologique des études microéconomiques sur l’investissement en capital humain. Il présente également une synthèse des études canadiennes sur l’investissement en capital humain en insistant sur les limites portant essentiellement sur la non prise en compte de l’hétérogénéité des systèmes de prêts et bourses et des systèmes fiscaux à travers les provinces canadiennes et la faible analyse de la répartition des coûts et bénéfices de l’investissement en éducation au Canada. Le second chapitre présente la méthodologie de mesure des rendements de l’éducation et des gains issus des investissements en éducation. Il décrit les données utilisées et les résultats des régressions économetriques. Finalement, le chapitre présente SIMAID, un calculateur d’aide financière aux études élaboré pour les objectifs dans cette thèse et qui permet d’estimer le montant de l’aide financière devant être attribuée à chaque étudiant en fonction de ses caractéristiques personnelles et de celles de sa famille. Dans sa première section, le troisième chapitre présente les rendements sociaux, privés et publics de l’éducation et montre que les rendements de l’éducation varient selon les provinces, les filières de formation, le genre et les cohortes d’année de naissance et décroient avec le niveau d’éducation. Dans sa seconde section, le chapitre montre que l’aide financière aux études accroît le rendement des études du baccalauréat de 24.3% et 9.5% respectivement au Québec et en Ontario. Finalement, le chapitre indique qu’un changement du système d’aide financière aux études de Québec par celui de l’Ontario entraîne une baisse de 11.9% du rendement des études au baccalauréat alors qu’un changement du système fiscal québécois par celui ontarien entraine une hausse du rendement du baccalauréat de 4.5%. L’effet combiné du changement des systèmes d’aide financière et fiscal est une baisse du rendement du baccalauréat de 7.4%. Le quatrième chapitre fournit une décomposition comptable détaillée des gains sociaux, privés et publics des investissements en éducation. Le gain social de l’investissement au baccalauréat est de $738 384 au Québec et de $685 437 en Ontario. Ce gain varie selon les filières de formation avec un niveau minimal pour les études humanitaires et un niveau maximal pour les études en ingénierie. Le chapitre montre également que la répartition des bénéfices et des coûts de l’investissement en éducation entre les individus et le gouvernement est plus équitable en Ontario qu’à Québec. En effet, un individu qui investit à Québec supporte 51.6% du coût total et engrange 64.8% des gains alors que le même individu supporterait 62.9% des coûts sociaux et engrangerait 62.2% des gains en Ontario. Finalement, le cinquième chapitre présente et analyse les effets rédistributifs des transferts et des taxes suite à un investissement en éducation. Il examine aussi si l’aide financière aux études est effectivement allouée aux personnes les plus pauvres. L’argument selon lequel l’aide financière est destinée aux plus pauvres est rejeté en analysant la distribution du revenu permanent. En effet, il ressort que 79% des personnes bénéficiant de l’aide financière aux études se trouvent dans le cinquième quintile de la distribution des revenus permanents. Le chapitre montre également que l’investissement en éducation impacte positivement les effets rédistributifs en 2006, 2001 et 1996 et négativement en 1991 et 2011. L’impact est également perceptible sur les composantes de l’effet rédistributif. Toutefois, la sensibilité de l’impact au taux d’actualisation dépend de l’indice utilisé dans l’analyse.

The fisheries sector is vital to the Philippine economy, providing substantial employment and income, contributing export earnings, and meeting local food security and nutrition requirements. To protect coastal and marine habitat and to sustain fisheries, over 1000 marine protected areas (MPAs) have been established, in the Philippines. This paper provides empirical evidence on the variance of net revenues linked with MPA establishment and the possible range of relocation costs for fishing effort displaced by an MPA. A total of 424 households were randomly selected from 18 barangays (villages) adjacent to MPAs in three regions in the Philippines. Results show that incomes decrease significantly for both fulltime and seasonal types of fishers after 1-3 years of MPA establishment. The loss occurring through MPA is higher than expected and at least on the short run (up to 4 years) the spill-over effect does not compensate. This information helped to determine the necessary conditional cash transfers for coastal communities who are highly dependent on coastal and marine resources.

A presente dissertação tem como tema central um modelo construtivo de arquitectura em terra, designadamente o tabique. Este modelo construtivo ancestral de alvenarias reserva na sua génese inúmeras particularidades, que vão desde as mais variadas formas de concepção do modelo por parte dos diferentes povos espalhados pelo mundo aos valiosos contributos sociais e ambientais. Na sua essência, o tabique foi muito utilizado por pessoas de parcos recursos económicos em soluções, por vezes muito engenhosas, levando-as a recorrer à mãe natureza para extrair dela os materiais necessários para a construção das suas casas. Um pouco por todo o mundo existem exemplares deste modelo tradicional contribuindo activamente para o enriquecimento dum vasto espólio de arquitectura em terra, matéria esta que tem vindo a ganhar um novo alento de acordo com as actuais “políticas" ecológicas. Deste modo e ao abrigo dos princípios gerais da conservação e restauro do património, o tabique detém informação relevante no que respeita à sustentabilidade do planeta, tornando o tema mais apelativo ao debate e à planificação de novas acções, envolvendo cada vez mais os profissionais em prol de um objectivo que garanta ao planeta um futuro mais próspero e equilibrado.

L’objectif général des travaux présentes dans cette thèse de doctorat était d’établir la relation entre l’alimentation et la composition du lait des vaches laitières, en mettant l’emphase sur les teneurs en matières grasses (TMG), sur l’urée du lait et sur l’efficience d’utilisation de l’azote. Pour la TMG, c’est principalement la relation entre cette teneur et la différence alimentaire cations-anions (DACA) qui a été investiguée. Une base de données de 2 142 troupeaux québécois a été utilisée et la relation entre la composition de la ration, incluant la DACA, et la TMG du lait a été déterminée à l’aide de régressions multiples. Il a été possible de prédire entre 32 et 66 % de la variation de la TMG du lait en fonction du stade de lactation. Malgré plusieurs interactions trouvées, une augmentation de la DACA, une supplémentation avec de l’acide palmitique et une distribution des aliments en ration totale mélangée ont eu une relation positive avec la TMG du lait, tandis qu’une augmentation de la proportion de concentrés dans la ration a eu un effet négatif. Les modèles développés ont montré l’importance de la gestion de l’alimentation sur la TMG du lait. En plus, ils ont démontré l’intérêt de considérer la DACA dans la formulation de rations chez la vache laitière. Dans une deuxième étude, la même base des données a été utilisée pour identifier les facteurs nutritionnels qui peuvent faire varier la teneur en urée du lait. Contrairement à ce qui est mentionné dans la littérature, tant des corrélations positives et que négatives entre les teneurs en urée du lait et en protéines des rations à l’intérieur des troupeaux sur une période de 36 mois ont été obtenues. Pour mieux comprendre ces relations, les résultats de performances et d’alimentation de 100 troupeaux avec des corrélations positives (r > 0,69) et de 100 troupeaux avec des corrélations négatives (r < -0,44) entre la teneur en urée du lait et en protéine brute de la ration ont été comparés. Les résultats n’ont pas montré de différences entre les deux groupes ni pour la composition de la ration, ni pour l’urée du lait. Ces résultats ne permettent pas d’identifier le meilleur contexte pour l’utilisation de la teneur en urée du lait comme un outil de gestion de l’alimentation. Ces observations soulèvent des questions sur la validité de l’utilisation des statistiques d’alimentation provenant de la base de données utilisée pour des évaluations nutritionnelles plus spécifiques. Considérant les résultats du projet précédent, le dernier projet visait à mieux comprendre les caractéristiques des fermes avec différentes efficiences d’utilisation de l’azote en utilisant des données plus fiables. Ainsi, 100 fermes laitières au Québec ont été visitées pour recueillir les données de production, de consommation d’aliments et de gestion de leur troupeau. Ces fermes ont été divisées en quatre groupes par une analyse en grappes selon leur efficience d’utilisation de l’azote. La comparaison entre les groupes a montré que les fermes dans les groupes avec une plus haute efficience d’utilisation d’azote ont une production laitière moyenne par vache plus élevée. Pour les stratégies d’alimentation, les fermes plus efficientes donnent plus d’énergie, mais moins de protéines brutes que les fermes des groupes moins efficients. Les résultats ont également montré l’importance de la prise alimentaire des vaches sur l’efficience d’utilisation de l’azote puisque les fermes des groupes avec la plus grande efficience étaient également celles avec la plus faible prise alimentaire. Aussi, les résultats n’ont pas permis d’établir clairement la relation entre la teneur en urée du lait et l’efficience de l’utilisation de l’azote. En effet, des valeurs différentes pour l’urée du lait étaient obtenues entre le groupe plus efficient et le moins efficient, mais la faible ampleur de variation de l’efficience d’utilisation de l’azote des groupes intermédiaires n’a pas permis d’observer de différences pour l’urée du lait. Finalement, outre une réduction des risques de pollution, les fermes des groupes plus efficaces pour l’utilisation de l’azote étaient également celles avec la marge sur les coûts d’alimentation par les vaches plus élevées. Par conséquent, il y a aussi un intérêt économique à améliorer l’efficience de l’utilisation de l’azote sur les fermes.

Background: Various factors have been investigated to account for the higher premature death rates in Scotland compared to England. Higher levels of deprivation in Scotland provide a partial explanation for these differences but recent work comparing areas of the UK with similar deprivation profiles and low life expectancy has shown that this is not the only reason. One hypothesis yet to be tested adequately is differences in diet and nutrition. Objective: To conduct a comparative analysis of dietary intake between Scotland and England using pooled food purchase data from the Living Costs and Food Survey (LCFS) from 2001 to 2012 and to assess differences in equivalised income quintiles (controlling for survey year, age of household reference person, and age household reference person left full-time education). Results: Lower intakes of fruit and vegetables, oil rich fish, fibre, vitamin A, folate, vitamin C and vitamin D and higher intakes of red and processed meat, whole milk, butter, savoury snacks, confectionary, soft drinks, saturated fat and NMES (added sugar and sugar in fruit juice), sodium and alcohol were found for Scotland compared to England. Differences between Scotland and England were higher for those on lower incomes for dietary components known to be related to health outcomes. For example fruit consumption was 14g/day lower for the lowest income quintile compared to 4 g/day lower in the highest quintile for Scotland versus England. Conclusions: A poorer diet in Scotland compared to England, particularly among disadvantaged groups, is likely to be one of the reasons for excess mortality. The current evidence on the continued poor diet in Scotland, particularly in disadvantaged groups, should not be ignored. Identifying effective, culturally appropriate approaches to improve diet across the population and notably in the most deprived areas needs further investment. Funded by NHS Health Scotland.

Fisheries are very important to Uganda's economy. The sector provides a vital source of food, recreation, trade and socioeconomic well being for the people and community globally. The fisheries of small lakes are important for producing fish for local populations who are not near the large lakes. These satellite lakes support important fisheries and other economic activities like fishing, water for domestic purposes and tourism, besides socio-cultural values. A number-of fish;- species, some of which were found only in Lake Victoria have been depleted through over-exploitation, introduction of exotics especiaily Nile perch and environmental degradation. Some of these fishes have been observed to survive in satellite lakes in the Victoria and Kyoga Lake basins. The Nabugabo satellite lakes (Manywa, Kayugi and Kayanja) contain endemic Cichlid fish species acting as reservoirs and therefore very important for conservation of fish biodiversity. Despite the socio-economic importance and uniqueness of these satellite lakes little research on socio-economic studies has been carried out. The sustainability of the lake is being threatened by increasing human activities. The fish stocks and species diversity are declining and this poses a threat to the livelihood of the people who depend on fish for food and income. Arising from this need a study was carried out to establish the socio-economic aspects of Nabugabo fisheries and implications for management, on which basis resource users would be made aware of the impacts of their activities. It was hoped that this would go further to ensure wise use and management of the resources by the users. The specific objectives were identifying activities around the lake, establishing socioeconomic values attached to the lake, identifying problems of the lake and resource users and examining existing local based management institutions. Results show that the activities taking place around the lakes include fishing, farming, watering of animals, deforestation and charcoal burning, brick making, resort beach development and food and refreshment. The major problem facing the lake was found to be encroachment of Hippo grass (Vossia) on the lake, which is decreasing the size of the lake, and limiting open waters for fishing (this only applied to Lake Nabugabo). Other important problems include use of illegal fishing methods, declining fish stocks and loss of cultural identity. The resource users are most pressed by the low incomes resulting from poor fish catches, theft of gears and lack of market. On examining the resource base for the lakes, it was only Lake Nabugabo that had a Landing Management Committee. The other three lakes did not have leadership institutions in place except the local councils for the respective villages. This was probably due to observed limited fisheries activities. Majority of the respondents agreed that Government and other service providers should work jointly to supplement local beach management committees in the management of the lakes resources. This is a good gesture because with increase in fishing effort and rampant use of illegal fishing methods, there is need to strengthen management institutions present on the lake. This would require Government, local community and other service providers to work together in a participatory way to control environment-degrading activities and stop the use of illegal fishing methods. Burning of vegetation on the lake should be stopped since it enhances growth of this grass. Finally, traditional taboos; which are present on some of the Nabugabo lakes, should be enhanced, as away of preserving them.

This dissertation explores three aspects of the economics and policy issues surrounding retail payments (low-value frequent payments): the microeconomic aspect, by measuring costs associated with retail payment instruments; the macroeconomic aspect, by quantifying the impact of the use of electronic rather than paper-based payment instruments on consumption and GDP; and the policy aspect, by identifying barriers that keep countries stuck with outdated payment systems, and recommending policy interventions to move forward with payments modernization. Payment system modernization has become a prominent part of the financial sector reform agenda in many advanced and developing countries. Greater use of electronic payments rather than cash and other paper-based instruments would have important economic and social benefits, including lower costs and thereby increased economic efficiency and higher incomes, while broadening access to the financial system, notably for people with moderate and low incomes. The dissertation starts with a general introduction on retail payments. Chapter 1 develops a theoretical model for measuring payments costs, and applies the model to Guyana—an emerging market in the midst of the transition from paper to electronic payments. Using primary survey data from Guyanese consumers, the results of the analysis indicate that annual costs related to the use of cash by consumers reach 2.5 percent of the country’s GDP. Switching to electronic payment instruments would provide savings amounting to 1 percent of GDP per year. Chapter 2 broadens the analysis to calculate the macroeconomic impacts of a move to electronic payments. Using a unique panel dataset of 76 countries across the 17-year span from 1998 to 2014 and a pooled OLS country fixed effects model, Chapter 2 finds that on average, use of debit and credit cards contribute USD 16.2 billion to annual global consumption, and USD 160 billion to overall annual global GDP. Chapter 3 provides an in-depth assessment of the Albanian payment cards and remittances market and recommends a set of incentives and regulations (both carrots and sticks) that would allow the country to modernize its payment system. Finally, the conclusion summarizes the lessons of the dissertation’s research and brings forward issues to be explored by future research in the retail payments area.

Modern medicine began in the last half of the nineteenth century when doctors started practising the scientific method at the bedside. However, in his presidential address to the Association of American Physicians in 1979 James Wyngaarden postulated that the clinical scientist was an endangered species. Several reasons for this have been suggested, including “the seductive incomes that now derive from procedure-based specialty medicine”. Others have suggested that it is simply because the things left to be discovered at bedside have become exhausted, and that all the big medical advances will now be made by high-powered institutions.

In the course of integrating into the global market, especially since China’s WTO accession, China has achieved remarkable GDP growth and has become the second largest economy in the world. These economic achievements have substantially increased Chinese incomes and have generated more government revenue for social progress. However, China’s economic progress, in itself, is neither sufficient for achieving desirable development outcomes nor a guarantee for expanding peoples’ capabilities. In fact, a narrow emphasis on GDP growth proves to be unsustainable, and may eventually harm the life quality of Chinese citizens. Without the right set of policies, a deepening trade-openness policy in China may enlarge social disparities and some people may further be deprived of basic public services and opportunities. To address these concerns, this dissertation, a set of three essays in Chapters 2-4, examines the impact of China's WTO accession on income distribution, compares China’s income and multidimensional poverty reduction and investigates the factors, including the WTO accession, that predict multidimensional poverty. By exploiting the exogenous variation in exposure to tariff changes across provinces and over time, Chapter 2 (Essay 1) estimates the causal effects of trade shocks and finds that China’s WTO accession has led to an increase in average household income, but its impacts are not evenly distributed. Households in urban areas have benefited more significantly than those in rural areas. Households with members working in the private sector have benefited more significantly than those in the public sector. However, the WTO accession has contributed to reducing income inequality between higher and lower income groups. Chapter 3 (Essay 2) explains and applies the Alkire and Foster Method (AF Method), examines multidimensional poverty in China and compares it with income poverty. It finds that China’s multidimensional poverty has declined dramatically during the period from 1989-2011. Reduction rates and patterns, however, vary by dimensions: multidimensional poverty reduction exhibits unbalanced regional progress as well as varies by province and between rural and urban areas. In comparison with income poverty, multidimensional poverty reduction does not always coincide with economic growth. Moreover, if one applies a single measure ─ either that of income or multidimensional poverty ─ a certain proportion of those who are poor remain unrecognized. By applying a logistic regression model, Chapter 4 (Essay 3) examines factors that predict multidimensional poverty and finds that the major factors predicting multidimensional poverty in China include household size, education level of the household head, health insurance coverage, geographic location, and the openness of the local economy. In order to alleviate multidimensional poverty, efforts should be targeted to (i) expand education opportunities for the household heads with low levels of education, (ii) develop appropriate geographic policies to narrow regional gaps and (iii) make macroeconomic policies work for the poor.

The electricity market and climate are both undergoing a change. The changes impact hydropower and provoke an interest for hydropower capacity increases. In this thesis a new methodology was developed utilising short-term hydropower optimisation and planning software for better capacity increase profitability analysis accuracy. In the methodology income increases are calculated in month long periods while varying average discharge and electricity price volatility. The monthly incomes are used for constructing year scenarios, and from different types of year scenarios a long-term profitability analysis can be made. Average price development is included utilising a multiplier. The method was applied on Oulujoki hydropower plants. It was found that the capacity additions that were analysed for Oulujoki were not profitable. However, the methodology was found versatile and useful. The result showed that short periods of peaking prices play major role in the profitability of capacity increases. Adding more discharge capacity to hydropower plants that initially bypassed water more often showed the best improvements both in income and power generation profile flexibility.

Tropical forests have decreased drastically especially in the Peruvian Amazon. In Peru deforestation is caused especially by migrant people; building of houses and infrastructure, clearing land for agricultural purposes and illegal logging and mining. Deforestation results in hindering ecosystem vitality, boosting climate change and decreasing livelihood possibilities. As a counterpoint to cutting down trees there is reforestation, which refers to re-establishment of forest cover. Deforestation and reforestation can be analysed in the light of Forest Transition theory. According to it, due to economic growth, the amount forest cover first diminishes but then starts to increase as the economy in general strengthens. Thus, the research framework is set to this theory. In this study the focus is on analysing socioeconomically sustainable reforestation possibilities in the community of Tingana, Peru. It is situated in a municipal conservation area around which deforestation has been heavy. Land cover change is analysed from LandsatTM satellite images covering a 15 year time period, 1995–2010, in the surroundings of the study area. Semi-structured interviews have been done with a sample size of 25 people and shed light on the perspectives on forests, reforestation and economical activities. The synthesis created from the two methods gives information about the possibilities to enforce reforestation in Tingana and the phase of forest transition in the area. The results show that forest cover has decreased around the surroundings of Tingana leaving the conservation area isolated from larger forest areas. Knowing that forest cover has also decreased inside the conservation area due to agricultural expansion it is certain that fragmentation harms biodiversity causing changes in local climate, which can have knock-on effects for farming and local livelihoods. Therefore reforestation is welcomed when it ensures both conservation and financial benefits and when carried out on locals’ terms. Regarding conservation and incomes the best option would be to plant native timber species together with fruit production species to create agroforestry systems. Economically the community should aim towards an economy that relies on ecotourism as it already practiced in the area. Reforestation could increase ecotourism, which then could in turn increase reforestation via revenues. Regarding forest transition it is likely that forest re-establishment will occur if reforestation along with ecotourism is implemented on long time scale.
