The integration of dispatchable renewable energies like biomass, geothermal and reservoir hydro technologies into an electrical network present no greater challenge than the integration of conventional power technologies for which are well understood by Eskom engineers. However, renewable energies that are based on resources that fluctuate throughout the day and from season to season, like wind and solar, introduce a number of challenges that Eskom engineers have not dealt with before. It is current practice for Eskom‟s generation to follow the load in order to balance the demand and supply. Through Eskom‟s load dispatching desk at National Control, generator outputs are adjusted on an hourly basis with balancing reserves making up only a small fraction of the total generation. Through the Integrated Resource Plan for Electricity of 2010, the Department of Energy has set some targets towards integrating renewable energy, including wind and solar generation, into the South African electricity market consequently introducing variability on the supply side. With demand that varies continually, maintaining a steady balance between supply and demand is already a challenging task. When the supply also becomes variable and less certain with the introduction of non-dispatchable renewable energy, the task becomes even more challenging. The aim of this research study is to determine whether the resources that previously helped to balance the variability in demand will still be adequate to balance variability in both demand and supply. The study will only concentrate on variable or non-dispatchable renewable energies as will be added to the South African electrical network according to the first two rounds of the Department of Energy‟s Renewable Energy Independent Power Producer Procurement Programme. This research study only looks into the balancing challenge and does not go into an analysis of voltage stability or network adequacy, both of which warrant in depth analysis. / Thesis (MIng (Development and Management Engineering))--North-West University, Potchefstroom Campus, 2013.

En los últimos años se ha desarollado mucho la literatura que utiliza modelos estocásticos de equilibrio económico general en economía abierta. En esta clase de modelos el primer capítulo estudia si el banco central tiene que fijarse en al inflación medida mirando al los precios al consumo (CPI) o a los precios a la producción. Se demonstra como la introducción de competencia monopolística en el mercado del trabajo y rigidez de los salarios nominales justifica el utilizo de la inflación medida sobre CPI. En el segundo capítulo el enfoque es sobre las diferentes volatilidades de la inflación entre paísos de la unión monetaria y como esto se puede relacionar con diferentes estructuras del mercado del trabajo. En el último capítulo se utiliza un modelo a dos paísos para estudiar las consecuencias de una subida del precio del petróleo sobre la inflación, los salarios reales y el producto interno bruto. / In these last years there has been an increasing literature developing DSGE Open Economy Models with market imperfections and nominal rigidities. It is the so called "New Open Economy Macroeconomics". Within this class of models the first chapter analyses the issue of whether the monetary authority should target Consumer Price Index (CPI) inflation or domestic inflation. It is shown that the introduction of monopolistic competition in the labour market and nominal wage rigidities rationalise CPI inflation targeting. In the second chapter we introduce matching and searching frictions in the labour market and relate different labour market structures across European countries with differences in the volatility of inflation across the same countries. In the last chapter we use a two-country model with oil in the production function and price and wage rigidities to relate movements in wage and price inflation, real wages and GDP growth rate to oil price changes.

La acumulación de Capital Humano es fundamental para explicar recientes procesos de crecimiento económico experimentados en numerosos países, los cambios en la distribución de la renta salarial, en la localización de la actividad productiva, del comercio, etc... Por ello, consideramos fundamental avanzar en el conocimiento que dicha acumulación haya podido tener en una economía como la española, caracterizada recientemente por un crecimiento intenso en la educación de los trabajadores. Por este motivo se realizan tres análisis. En el primero, descomponemos la distribución de los salarios para conocer qué factores han afectado a su cambio desde 1980. Dedicamos especial atención al efecto que el cambio educativo haya podido tener en la desigualdad salarial. En un segundo análisis descomponemos el cambio en la brecha salarial entre trabajo cualificado y no cualificado entre cambios en la demanda y oferta de cualificación. Por último, estimamos las externalidades del capital humano en España a nivel regional. / Human Capital accumulation is crucial for explaining countries' recent economic growth episodes, changes in income and wage distribution, production localization, trade, etc. Thus, we consider important enhance the knowledge for the Human Capital accumulation effects on Spanish economy, characterized by intensive growth of educated workers. Then, we do three analysis. First, we decompose the wage distribution to know which factors are behind its changes since 1980. We give special attention to education effects on that wage inequality change. In our second analysis, we decompose the more educated wage premium change between changes in demand and supply of skills. Finally, our third analysis try to estimate human capital externalities for Spanish regions.

Why do temporary foreign workers employed in the British Columbia hospitality sector have difficulty enforcing their workplace rights? Using the themes of people, place and time, this thesis explores the demand and supply of migrant workers in the British Columbia hospitality sector, and the challenges temporary foreign workers face at the intersection of immigration law, employment law, occupational health and safety law, and workers’ compensation law. The thesis argues that the low-skilled Temporary Foreign Worker Program shifts the negative consequences of unfair working conditions and workplace health and safety risks over people, place and time: from Canadian workers and employers onto temporary foreign workers; from Canada to elsewhere; and from the present into the future. Workplace rights are not enough for hospitality sector workers, what is needed is better tools for the enforcement of those rights. / Graduate

Logit and Random Coefficients Logit are examples of demand models used to study these effects. For the supply side it is generally supposed a Nash equilibrium in prices. This work presents a detailed discussion of these models of demand and supply as well as the procedure for estimation. Lastly, is made an application to the Brazilian fixed income fund market. / Estimação de demanda e oferta em mercados com produtos diferenciados é uma questão central em organização industrial empírica e tem sido usada para estudar os efeitos de taxas, fusões, introdução de novos bens, poder de mercado, dentre outros. Logit e Logit com coeficientes aleatórios são exemplos de modelos de demanda utilizados para estudar estes efeitos. Para a oferta geralmente é suposto equilíbrio de Nash em preços. Este trabalho apresenta uma discussão detalhada destes modelos de demanda e oferta, assim como o procedimento para estimação. Por fim é feita uma aplicação para o mercado brasileiro de fundos de renda fixa.

In der Ukraine sind der demographische Wandel und der damit verbundene Bevölkerungsrückgang von 12 % der Einwohner seit 1990 im europaweiten Vergleich einmalig. Dafür verantwortlich ist aus Sicht der Wissenschaft neben den transformationsbedingten Brüchen innerhalb der Gesellschaft, der flächendeckende Mangel an bezahlbaren Wohnungen. Aktuell ist die Hälfte der ukrainischen Haushalte mit der eigenen Wohnungssituation unzufrieden. Der Großteil des in den 1990er Jahren privatisierten Wohnungsbestands ist marode und in sanierungsbedürftigem Zustand. Den Eigentümern fehlen jedoch die finanziellen Mittel, um Bestandserhaltungsmaßnahmen aus eigener Kraft heraus durchzuführen. Vor allem junge Erwachsene haben keine Zugriffsmöglichkeiten auf eine Wohnung und damit auch keine Chance, einen eigenen Haushalt zu bilden. Oft scheitern daran die Gründung einer eigenen Familie und der Wunsch, Kinder zu bekommen. Die vorliegende Arbeit hat das Ziel, Hinweise auf Zusammenhänge zwischen dem demographischen Wandel, den Haushalten und den bestehenden Wohnungsproblemen in der Ukraine zu finden. Dazu werden die Entwicklungen der Bevölkerung, der Haushalte und des Wohnungsbestands anhand sachlogischer Kenngrößen charakterisiert und regionale Besonderheiten sowie Disparitäten zwischen den 27 Oblasten (Regionen) des Landes aufgezeigt. Basierend auf multivariaten Verfahren, wie der Faktoren- und Clusteranalyse, werden Regionstypen gebildet, die Aussagen zur aktuellen Nachfrage und zum Angebot an Wohnungen zulassen.

Due to the increasingly uncertain environments that global supply chains operate within, both due to component shortages and other types of challenges, the possibility of managing demand variability and balancing it with supply capabilities is getting more challenging. The primary way to deal with these fluctuations in demand is by building flexibility in the supply chain to meet the variations that occur and keep the customers satisfied. However, when flexibility is not enough, and the supply chain becomes increasingly strained due to geopolitical factors and customers demanding higher customizations, more efforts are required to manage the variability. This study investigates the possibility that instead of relying solely on flexibility, try to deal with the variations that arise in demand. This relates both to internal processes that increase variation but also to the variations that are caused by actual changes in demand. The study partly examines what drives internal variation and how one should work to minimize it. Moreover, concerning the external variation, demand shaping theory is applied. This is to understand how external variation can be handled by trying to steer the demand. As the theory in previous studies has primarily been applied in B2C contexts, the applicability of the theory in a B2B context is also examined. Furthermore, the study also investigates how demand and supply should be integrated to utilize the concepts in the best way possible when managing demand variability. The study has been conducted through a case study at Ericsson, where people who work within sales and supply have participated and contributed with their knowledge. The results show the importance of integration between different functions to succeed in managing demand variations and having a more significant impact on what customers buy. This means both clear communication, internally and externally, and the importance of having a unified vision and incentives that drive the company towards the same goal. In addition, the results also show that although the academic literature is mainly aimed at B2C companies, it is possible to apply the concept to B2B companies as well. / Till följd av den alltmer osäkra omvärld som globala leveranskedjor arbetar inom, med både komponentbrist och andra typer av utmaningar, blir det allt svårare att hantera den varierande efterfrågan och balansera den mot den kapacitet som företag besitter. Det primära sättet att hantera dessa fluktuationer i efterfrågan är genom att bygga in flexibilitet för att kunna bemöta de variationer som uppstår och för att behålla kunder nöjda. När flexibiliteten inte räcker till och leveranskedjan blir alltmer ansträngd, på grund av geopolitiska faktorer och kunder som kräver alltmer kundanpassade produkter, behöver man arbeta än mer med att försöka hantera variationen som uppstår. Syftet med denna studie är därför att undersöka möjligheten att, i stället för att enbart förlita sig på flexibilitet, försöka hantera de variationer som uppstår i efterfrågan. Detta relaterar både till interna processer som driver variationen men också de variationer som orsakas av faktiska förändringar i efterfrågan. Studien undersöker vad det är som driver intern variation och hur man bör arbeta för att minimera denna. I relation till den externa variationen, används bland annat demand shaping teori för att förstå hur denna typ av variation kan hanteras genom att försöka ha mer inflytande över vad kunderna väljer att köpa. Då teorin i tidigare studier enbart applicerats i B2C sammanhang, undersöks även om teorin är applicerbar i en B2B kontext. Studien undersöker också hur funktioner inom försäljning och supply bör integreras för att möjliggöra detta. Studien har genomförts som en fallstudie på Ericsson där personer som arbetar inom försäljning och supply deltagit och bidragit med sin kunskap. Resultaten visar på vikten av integration mellan olika funktioner för att lyckas hantera demand variationer och på att ha större inverkan på det kunderna köper. Detta innebär tydlig kommunikation både internt och externt, samt värdet av att ha gemensamma mål och incitament som driver företaget mot samma vision. Resultaten visar dessutom på att det finns förutsättningar för att applicera det undersökta konceptet på B2B företag trots att den akademiska litteraturen främst riktat in sig mot B2C företag.

Dans cette thèse, je me suis intéressé aux effets des fluctuations du prix de pétrole sur l'activité macroéconomique selon la cause sous-jacente ces fluctuations. Les modèles économiques utilisés dans cette thèse sont principalement les modèles d'équilibre général dynamique stochastique (de l'anglais Dynamic Stochastic General Equilibrium, DSGE) et les modèles Vecteurs Autorégressifs, VAR. Plusieurs études ont examiné les effets des fluctuations du prix de pétrole sur les principaux variables macroéconomiques, mais très peu d'entre elles ont fait spécifiquement le lien entre les effets des fluctuations du prix du pétrole et la l'origine de ces fluctuations. Pourtant, il est largement admis dans les études plus récentes que les augmentations du prix du pétrole peuvent avoir des effets très différents en fonction de la cause sous-jacente de cette augmentation. Ma thèse, structurée en trois chapitres, porte une attention particulière aux sources de fluctuations du prix de pétrole et leurs impacts sur l'activité macroéconomique en général, et en particulier sur l'économie du Canada. Le premier chapitre examine comment les chocs d'offre de pétrole, de demande agrégée, et de demande de précaution de pétrole affectent l'économie du Canada, dans un Modèle d'équilibre Général Dynamique Stochastique estimé. L'estimation est réalisée par la méthode Bayésienne, en utilisant des données trimestrielles canadiennes sur la période 1983Q1 à 2010Q4. Les résultats montrent que les effets dynamiques des fluctuations du prix du pétrole sur les principaux agrégats macro-économiques canadiens varient en fonction de leurs sources. En particulier, une augmentation de 10% du prix réel du pétrole causée par des chocs positifs sur la demande globale étrangère a un effet positif significatif de l'ordre de 0,4% sur le PIB réel du Canada au moment de l'impact et l'effet reste positif sur tous les horizons. En revanche, une augmentation du prix réel du pétrole causée par des chocs négatifs sur l'offre de pétrole ou par des chocs positifs de la demande de pétrole de précaution a un effet négligeable sur le PIB réel du Canada au moment de l'impact, mais provoque une baisse légèrement significative après l'impact. En outre, parmi les chocs pétroliers identifiés, les chocs sur la demande globale étrangère ont été relativement plus important pour expliquer la fluctuation des principaux agrégats macroéconomiques du Canada au cours de la période d'estimation. Le deuxième chapitre utilise un modèle Structurel VAR en Panel pour examiner les liens entre les chocs de demande et d'offre de pétrole et les ajustements de la demande de travail et des salaires dans les industries manufacturières au Canada. Le modèle est estimé sur des données annuelles désagrégées au niveau industriel sur la période de 1975 à 2008. Les principaux résultats suggèrent qu'un choc positif de demande globale a un effet positif sur la demande de travail et les salaires, à court terme et à long terme. Un choc négatif sur l'offre de pétrole a un effet négatif relativement faible au moment de l'impact, mais l'effet devient positif après la première année. En revanche, un choc positif sur la demande précaution de pétrole a un impact négatif à tous les horizons. Les estimations industrie-par-industrie confirment les précédents résultats en panel. En outre, le papier examine comment les effets des différents chocs pétroliers sur la demande travail et les salaires varient en fonction du degré d'exposition commerciale et de l'intensité en énergie dans la production. Il ressort que les industries fortement exposées au commerce international et les industries fortement intensives en énergie sont plus vulnérables aux fluctuations du prix du pétrole causées par des chocs d'offre de pétrole ou des chocs de demande globale. Le dernier chapitre examine les implications en terme de bien-être social de l'introduction des inventaires en pétrole sur le marché mondial à l'aide d'un modèle DSGE de trois pays dont deux pays importateurs de pétrole et un pays exportateur de pétrole. Les gains de bien-être sont mesurés par la variation compensatoire de la consommation sous deux règles de politique monétaire. Les principaux résultats montrent que l'introduction des inventaires en pétrole a des effets négatifs sur le bien-être des consommateurs dans chacun des deux pays importateurs de pétrole, alors qu'il a des effets positifs sur le bien-être des consommateurs dans le pays exportateur de pétrole, quelle que soit la règle de politique monétaire. Par ailleurs, l'inclusion de la dépréciation du taux de change dans les règles de politique monétaire permet de réduire les coûts sociaux pour les pays importateurs de pétrole. Enfin, l'ampleur des effets de bien-être dépend du niveau d'inventaire en pétrole à l'état stationnaire et est principalement expliquée par les chocs sur les inventaires en pétrole. / In this thesis, I am interested in the effects of fluctuations in oil prices on macroeconomic activity depending on the underlying cause of these fluctuations. The economic models used in this thesis include the Dynamic Stochastic General Equilibrium (DSGE) Models and Vector Autoregressive (VAR) Models. Several studies have examined the effects of fluctuations in oil price on the main macroeconomic variables, but very few of theses studies have specifically made the link between the effects of fluctuations in oil prices and the origin of these fluctuations. However, it is widely accepted in more recent studies that oil price increases may have very different effects depending on the underlying cause of that increase. My thesis, structured in three chapters, is focused on the sources of fluctuations in oil price and their impacts on the macroeconomic activity in general, and in particular on the canadian economy. The first chapter of the thesis investigates how oil supply shocks, aggregate demand shocks, and precautionary oil demand shocks affect Canada's economy, within an estimated Dynamic Stochastic General Equilibrium (DSGE) model. The estimation is conducted using Bayesian methods, with Canadian quarterly data from 1983Q1 to 2010Q4. The results suggest that the dynamic effects of oil price shocks on Canadian macroeconomic variables vary according to their sources. In particular, a 10% increase in the real price of oil driven by positive foreign aggregate demand shocks has a significant positive effect of about 0.4% on Canada's real GDP upon impact and the effect remains positive over time. In contrast, an increase in the real price of oil driven by negative foreign oil supply shocks or by positive precautionary oil demand shocks causes an insignificant effect on Canada's real GDP upon impact but causes a slightly significant decline afterwards. The intuition is that a positive innovation in aggregate demand tends to increase the demand for Canada's overall exports. Oil supply disruptions in foreign countries or positive precautionary oil demand shocks increase the uncertainty about future oil prices, which leads firms to postpone irreversible investment expenditures, and tends to reduce Canada's real GDP. Furthermore, among the identified oil shocks, foreign aggregate demand shocks have been relatively more important in explaining the variations of most of Canadian macroeconomic variables over the estimation period. The second chapter examines the links between oil demand and supply shocks and labor market adjustments in Canadian manufacturing industries using a panel structural VAR model. The model is estimated with disaggregated annual data at the industry level from 1975 to 2008. The results show that a positive aggregate demand shock increases both labor and the price of labor over a 20-year period. A negative oil supply shock has a relatively small negative effect upon impact but the effect turns positive after the first year. In contrast, a positive precautionary oil demand shock has a negative impact over all horizons. The paper also examines how the responses to different types of oil shocks vary from industry to industry. The results suggest that industries with higher net trade exposure/oil-intensity are more vulnerable to oil price increases driven by oil supply shocks and aggregate demand shocks. The third chapter examines the welfare implications of introducing competitive storage on the global oil market using a three country DSGE model characterized by two oil-importing countries and one oil-exporting country. The welfare gains are measured by consumption compensating variation under two alternative monetary policy rules. The main results indicate that the introduction of oil storage has negative welfare effects for each of the two oil importing countries, while it has positive welfare effects for the oil exporting country, whatever the monetary policy rule. I also found that including the exchange rate depreciation in the monetary policy rules allows to slightly reduce the welfare costs for both oil importing countries. Finally, the magnitude of the welfare effects depends on the steady state level of oil storage and is mainly driven by oil storage shocks.

Το ζήτημα της μέτρησης των οικονομικών επιπτώσεων του τουρισμού (σε νομισματικά και μη νομισματικά μεγέθη) σε μία οικονομία αναφοράς έχει απασχολήσει έντονα την διεθνή κοινότητα. Ιδιαίτερα δε, έχει επισήμως αναγνωρισθεί ότι οι διάφορες μέχρι πρόσφατα σχετικές μετρήσεις ήταν αποσπασματικές, μη ορθολογικά συγκροτημένες και μη ολοκληρωμένες, έτσι ώστε να μην παρουσιάζεται η πραγματική συνολική εικόνα του ετήσιου μεγέθους του τουρισμού σε μία χώρα. Το ίδιο έχει αναγνωρισθεί επισήμως και στην Ελλάδα για τις διαδικασίες που ακολουθούντο έως σήμερα. Ο τουρισμός συνιστά ένα φαινόμενο που από οικονομικής απόψεως σημαίνει την ενεργοποίηση μίας ιδιαίτερα διαμορφούμενης ατομικής κατανάλωσης, για συγκεκριμένο χρονικό διάστημα, από τους επισκέπτες στον τόπο της επίσκεψης. Για την ικανοποίηση αυτής της ζήτησης για κατανάλωση η πλευρά της προσφοράς πρέπει να ανταποκριθεί. Αυτό σημαίνει τη μεταβολή σε κάθε μακροοικονομικό μέγεθος σε μία οικονομία. Οι μεταβολές αυτές πρέπει να διερευνηθούν και να μετρηθούν. Μόνο κάτω από αυτή τη διαδικασία είναι δυνατό να αναδειχθεί η συνεισφορά του τουρισμού στο σύνολο της οικονομίας, και να παρέχεται έτσι η αναγκαία πληροφορία για την χάραξη στρατηγικής και τις πολιτικές αποφάσεις, τόσο για το δημόσιο όσο και για τον ιδιωτικό τομέα. Συνεπώς, με βάση τη μέχρι σήμερα αδυναμία του κλασσικού εθνικολογιστικού συστήματος να παρέχει από την πλευρά της προσφοράς τις αναγκαίες αξιόπιστες μετρήσεις για την εξέλιξη του ετήσιου μακροοικονομικού μεγέθους του τουρισμού, αναπτύχθηκε και τέθηκε στη δημόσια διεθνή συζήτηση ένα ειδικό για το σκοπό αυτό εργαλείο, ο Δορυφόρος Λογαριασμός Τουρισμού (ΔΛΤ). Η διερεύνηση, η καταγραφή και η μεθοδολογική συγκρότηση του αναγκαίου για την Ελληνική οικονομία «ΔΛΤ» αποτελεί το αντικείμενο της παρούσας εργασίας. Η ανάλυση ξεκινά από την παρουσίαση του Συστήματος Εθνικών Λογαριασμών (ΣΕΛ) και των αδυναμιών να αντιμετωπίσει το τουριστικό φαινόμενο ως αναλυτική κατηγορία της εθνικής οικονομίας. Η εργασία συνεχίζεται με ανάλυση του ζητήματος του ΔΛΤ και καταλήγει ειδικά στην Ελληνική περίπτωση όσον αφορά την πρόοδο που έχει μέχρι σήμερα επιτευχθεί. Παρέχεται έτσι για πρώτη φορά για την ελληνική πραγματικότητα μία ολοκληρωμένη και προσαρμοσμένη παρουσίαση και ανάλυση των σχετικών ζητημάτων, με παράλληλη εμπειρική και μεθοδολογική κριτική των αντίστοιχων ενεργειών. Διευκρινίζονται έτσι τεκμηριωμένα διάφορα ζητήματα με κύριο αυτό του «τουριστικού τομέα» και της «τουριστικής βιομηχανίας». / The measurement of the economic impact of tourism (in monetary and non monetary data) in a reference economy is an issue of international concern. Especially, it has been officially accepted that the various relative measurements in the past were partial, not rationally structured, and not fully integrated. So, a complete picture for the real annual magnitude of tourism was not available. This is also the case of Greece for the procedures that have been followed in the past, as it has been officially accepted. From economic aspect, tourism is a phenomenon that means the activation of a specially formed individual consumption, for specific time, of visitors in the place of visit. In order this consumption demand to be satisfied, the supply side must meet it. That means the change in any macroeconomic item in an economy. These changes must be observed and measured. Only under this procedure the total contribution of tourism in an economy will be possible to be revealed, and the needed information for the strategic planning and political decisions, both for public and private sector, will be provided. Therefore, based on the weakness of the traditional system of national accounts to provide from the supply side the needed and credible measurements for the annual change of the size of tourism in macroeconomic terms, it has been developed and entered the international debate a special purpose tool, the Tourism Satellite Account (TSA). Researching, examine, writing down, and the methodological setting-up of the necessary for the Greek economy TSA constitute the subject of the present thesis. Starting point of the analysis is a presentation of the System of National Accounts and its weakness to cope with tourism phenomenon as a distinct category of national economy. An analysis of the TSA is following, and the doctoral thesis closes specifically with the case of Greece regarding the progress that has been achieved to date. Thus, for Greece, it is provided for the first time a complete and adapted presentation and analysis of that issue of concern, including an empirical and methodological criticism of the corresponding work. That leads in documenting and casting light on various issues, of which of much importance is that of “tourist sector” and “tourist industry”.
