Knowledge, learning, and innovation are vital elements in facilitating economic development and growth. Technological change, which is a synonym for generating knowledge, the diffusion thereof, and subsequent application in the marketplace in the form of novel products and processes, i.e. innovations, has a strong effect on the collective wealth of regions and nations. Knowledge spillovers, which are unintended knowledge flows that take place among spatial (geography) and sectoral (industry) units of observation, provide a rationale for diverging growth rates among spatial units, well beyond what might be explained by variations in jurisdictional factor endowments, and thus are of particular interest in this context. Measuring and quantifying the creation and diffusion of knowledge has proven to be a challenging endeavor. One way to capture technical and economically valuable knowledge is by means of patent and patent citation analysis. Following this approach, and utilizing a novel patent database that has been specifically developed for this purpose, the present dissertation investigates the spatio-sectoral patterns of knowledge spillovers in the Canadian economy over the time period 1983 to 2007. The employed research methodology addresses existing limitations in this stream of research, and contributes to the continuing debate regarding the significance of sectoral specialization versus diversity, and local versus non-local knowledge spillovers as the main driver of knowledge formation processes leading to innovation at the sub-regional scale. The findings indicate that knowledge spillovers are localized, and furthermore, that this localization effect has increased over time for both spillovers within a particular industry, as well as between industry sectors. The analysis of micro-geographic industry specific spatio-sectoral knowledge formation processes, and the inquiry into local sectoral knowledge spillover patterns, outlines how regional evolutionary technology trajectories potentially shape the rate and direction of technological change, and consequently influence economic growth, at a particular place.

Currently, the labeling of functional food products is highly regulated in Canada. Although certain nutrient content claims and five generic health claims have been allowed, the inability to make additional nutrient content and health claims decreases functional food firms incentives to produce and commercialize new and healthy food products. This, in turn, has consequences for functional food demand, consumer welfare, and health care costs. The primary objective of this thesis is to examine the potential welfare implications of functional food labeling for Canadian society.<p>A benefit cost analysis is conducted to examine a specific case study of omega-3 enriched eggs. The benefit cost analysis evaluates the welfare effects of functional food labeling policy and helps realize the magnitude of potential benefits that could be gained if not for restrictive and complicated labeling regulations. Based on a range of assumptions and using three different scenarios to cover a range of estimates, the health benefits from the reduction in the risk of coronary heart disease due to the current consumption of omega-3 enriched eggs, and the production and labeling-related costs are estimated. By comparing the estimated benefits and costs, the results indicate that the current consumption of omega-3 enriched eggs provides a considerable net economic gain. Therefore, labeling information on health components can contribute to facilitating a healthy lifestyle with reduced medical costs, stimulating agricultural innovation, and increasing economic welfare.<p>Realizing the positive overall impact that the current consumption of omega-3 enriched eggs has on consumers health and economy in Canada, a possible policy that could regulate all eggs to be enriched with omega-3 fatty acids is proposed. This policy could potentially be used to correct not only information asymmetry but also the negative externalities that are created by health and disability insurances. The benefit cost analysis show that the health benefits would be greatly increased while costs would slightly increase due to reduced labeling-related costs. Therefore, the results indicate that the net economic gain is even stronger if the mandatory development of omega-3 enriched eggs were required.

This paper investigates the impact of Familias en Acción, a conditional cash transfer program in Colombia, on participant credit behavior. The motivation of the research is derived from previous studies which indicate that conditional cash transfer programs have effects on households aside from those directly intentioned by the programs. While the direct impacts of Familias en Acción have been measured by the research team responsible for evaluating the program, potential indirect effects remain uninvestigated. My research specifically focuses on the impacts of the program on credit behavior. I compute estimates on the percent change in loan balance outstanding and credit participation over the four-year evaluation period by comparing households that are benefiting from the program (treatment) and those that are not (control). Because Familias en Acción was not a randomly assigned program, I use quasi-experimental data collected in three rounds over four years. I control for dissimilarities between the treatment and control group by utilizing a difference-in-differences approach and by controlling across a wide-range of observable household characteristics. I find that the program does affect credit behavior in treated households. In both urban and rural areas, the outstanding loan balance and the number of households involved in the credit market increases after the first year of the program. After four years of the program, the effect is still significant and positive in rural areas though not in urban areas. This indicates that the program affects credit behavior in all treated households in the short run and rural households in the long run. These findings provide new considerations for policy makers who are implementing these programs in developing countries.

This thesis examines the private and external costs of electricity generated in Ontario by natural gas, wind, refurbished nuclear and new nuclear power. The purpose of the assessment is to determine a capacity expansion plan that meets the forecasted electricity supply gap in Ontario at the lowest social costs (i. e. the lowest aggregated private and external costs). A levelized unit electricity cost (LUEC) analysis is employed to evaluate private costs under both public and merchant perspectives. Computable external costs are monetized by adapting estimates from the literature that were previously developed using a primarily bottom-up damage cost method. <br /><br /> The findings reveal that social cost estimates for nuclear refurbishment are the lowest of the generation alternatives studied regardless of the evaluation perspective. Therefore, if the capacity expansion decision were based solely on these estimates, nuclear refurbishment should be utilized until its capacity constraints are reached. The generation alternative with the second lowest social costs depends on the perspective from which private costs are evaluated: from a public perspective, the remainder of the supply gap should be filled by new nuclear generation and from a merchant perspective, which is assumed to be more reflective of the current Ontario electricity market, natural gas-fired generation should be used. <br /><br /> Due to inherent uncertainty and limitations associated with the estimation of social costs, the estimates obtained in this thesis are considered to be context and data specific. A sensitivity analysis, which is employed to attempt to mitigate some of the uncertainty, shows that changes to key variables alter the capacity expansion plan. This reinforces the observation that methods and assumptions significantly affect social cost estimates. <br /><br /> Despite the limitations of this kind of evaluation, it is argued that a social cost assessment that is consistent, transparent and comprehensive can be a useful tool to assess the trade-offs of electricity generation alternatives if used along with existing evaluation criteria. Such an assessment can increase the likelihood that actual social costs are minimized, which can steer electricity generation in Ontario towards a system that is more efficient and sustainable.

This thesis comprises of two separate game theoretic models that fall under the general umbrella of network formation games. The first is a coalitional model of interaction in social networks that is based on the idea of social distance, in which players seek interactions with similar others. Our model captures some of the phenomena observed on such networks, such as homophily driven interactions and the formation of small worlds for groups of players. Using social distance games, we analyze the interactions between players on the network, study the properties of efficient and stable networks, relate them to the underlying graphical structure of the game, and give an approximation algorithm for finding optimal social welfare. We then show that efficient networks are not necessarily stable, and stable networks do not necessarily maximise welfare. We use the stability gap to investigate the welfare of stable coalition structures, and propose two new solution concepts with improved welfare guarantees. The second model is a compact formulation of matchings with externalities. Our formulation achieves tractability of the representation at the expense of full expressivity. We formulate a template of solution concept that applies to games where externalities are involved, and instantiate it in the context of optimistic, neutral, and pessimistic reasoning. Then we investigate the complexity of the representation in the context of many-to-many and one-to-one matchings, and provide both computational hardness results and polynomial time algorithms where applicable.

The full cost of climate change is not accounted for in today’s financial reporting. Today’s sustainability reporting mainly consists of disclosures which do not affect any financial statement. If externalities were accounted for it would help stakeholders become aware of companies’ true sustainability. The purpose of this thesis is to identify and describe ways for companies to account for their climate impact, in general and by incorporating externalities into the financial statements. A qualitative method is used in the form of a descriptive case study with a Swedish perspective. The study is based on interviews with accountants and company representatives who work actively with sustainability reporting issues. The main finding of the study is that the best way to account for negative externalities is to use full cost accounting. However, it is difficult to use in practice since monetising externalities is difficult. The currently most used frameworks (the GRI guidelines and the GHG Protocol) account for externalities to some extent, but have no connection to financial reporting. An evolving framework within integrated reporting has the potential to increase the connection between the current disclosures in sustainability reports and financial reporting. So far the best solution to account for externalities is to separately account for taxes, fees and cap-and-trade since externalities are internalised in these costs. The effects of accounting for negative externalities will differ depending on the degree of climate impact the company has. It will also depend on how far down the value-chain emissions are accounted for. It will nevertheless be an incentive to reduce climate impact and act as a management tool. / Den fulla kostnaden av klimatförändringar redovisas inte i dagens finansiella redovisning. Dagens hållbarhetsredovisning består mestadels av upplysningar som inte påverkar några finansiella rapporter. Om externaliteter redovisades skulle det hjälpa intressenter att bli medvetna om företags verkliga hållbarhet. Syftet med uppsatsen är att identifiera och beskriva sätt för företag att redovisa sin klimatpåverkan. Både generellt och i de finansiella rapporterna. En kvalitativ metod används i form av en beskrivande fallstudie med svenskt perspektiv. Studien är baserad på intervjuer med redovisningskonsulter och företagsrepresentanter som arbetar aktivt med frågor som rör hållbarhetsredovisning. Den viktigaste slutsatsen av studien är att det bästa sättet att redovisa negativa externaliteter är att använda full cost accounting. Dock är det svårt att använda i praktiken eftersom det är svårt att monetärisera externaliteter. De för närvarande mest använda ramverken (GRIs riktlinjer och GHG Protocol) inkluderar till viss del externaliteter, men har ingen koppling till finansiella rapporter. Ett ramverk inom integrerad rapportering är under utveckling och det kan potentiellt öka kopplingen mellan upplysningarna i hållbarhetsredovisningar och finansiell rapportering. Den hittills bästa lösningen för att redovisa externaliteter är att separat redovisa miljöskatter, avgifter och handel med utsläppsrätter eftersom externaliteter internaliseras i dessa kostnader. Effekterna av att redovisa negativa externaliteter kommer att bero på företagets grad av klimatpåverkan. Det kommer också att bero på hur långt ner i värdekedjan utsläpp redovisas. Det kommer oavsett att bli ett incitament för att minska klimatpåverkan och fungera som ett verktyg för förvaltning och styrning av företaget.
