However, none of the previous works studied how the source of an economic downturn, if the economy is facing an adverse supply/demand shock, affects the effectiveness of fiscal expansions. We introduce in a simple New Keynesian model with a rich description of fiscal policy, the assumption of imperfectly informed policymakers (fiscal and monetary) to approach the question. Our results point out the existence of disparate effects of fiscal policy depending on whether the economy is facing a demand or a supply recession. Yet, we find out that cuts in taxes are an effective tool to counter the effects of adverse shocks on economic activity and aggregate consumption. / A atual literatura mensurando a magnitude do multiplicador fiscal apresenta um consenso considerável de que os efeitos estimulativos de instrumentos fiscais dependem do estado atual da atividade econômica, isto é, se o estímulo fiscal ocorre em uma recessão ou expansão econômica. Entretanto, nenhum dos trabalhos anteriores analisou a questão de se fonte da recessão, isto é, se o choque adverso tem uma natureza de demanda ou oferta, afeta a efetividade de expansões fiscais. Introduzimos em um modelo Novo Keynesiano com uma rica descrição de política fiscal, a hipótese de formuladores de política (fiscal e monetária) sujeitos à informação imperfeita, e quantificamos o multiplicador fiscal para responder a questão. Nossos resultados demonstram efeitos dispares da política fiscal dependendo da natureza do choque adverso. Entretanto, encontramos que cortes em tributos são efetivos para contrabalancear os efeitos recessivos desses choques sobre atividade econômica e consumo agregado.

Com a crise deste setor ocorrida no Brasil em 2001 a possibilidade de um apagão mostrou que o impacto sobre a sociedade pode ocorrer a qualquer momento. O mesmo se diz em relação a água devido sua iminente escassez. O Planejamento Integrado de Recursos (PIR) foi difundido como uma forma de gerenciar de maneira integral um recurso pelos lados da oferta e demanda e pode ser considerado uma opção viável ao planejamento convencional. Este trabalho fez um levantamento do estado da arte acerca do PIR energético e do Gerenciamento dos Recursos Hídricos. Aproveitando conceitos do setor de energia criou-se o Planejamento Integrado de Recursos da Água (PIRA) para ser utilizado no sistema de abastecimento público. O PIRA guia o gerenciamento integrado da água através da conservação desse recurso aliando a redução de desperdício com medidas de tarifação bem como aumentando a oferta a partir de opções alternativas como o reúso e o aproveitamento das águas pluviais / Abstract: The Water Resources Planning in use doesn't diverge substantially from the Traditional Energy Planning. With the energy crisis occurred in Brazil in 2001 the blackout possibility shows that the impact on the society might happen at any time. The same occurs to the water because of its scarcity. The Integrated Resource Planning (IRP) was diffused as a way of fully managing a resource by the supply and demand sizes and can be considerated a viable option for the conventional planning. This composition is meant to do a study of the specific bibliography about the energy IRP and the Water Resource Management. Utilizing conceptions of the energy area, Water Integrated Resource Planning has been created to be used at the public utilities. The Water Integrated Resource Planning conducts the Water Integrated Management through this resource saving, joining this to a different tax and increasing the supply with alternative options such as the wastewater and the rainwater use / Mestrado / Mestre em Planejamento de Sistemas Energéticos

The impact of minimum wages on the incentives of education for the youth

Kurdi, Heba January 2017 (has links)
The purpose of this thesis is to investigate the incentives regarding the education decisions, resulting from a minimum wage over the period 2005-2014. The question is investigated by comparing the changes in the wage dispersion and upper secondary graduation rate in 17 OECD countries. And then, by comparing the changes in the bites of the minimum wage and educational attainment for upper secondary students in 11 OECD countries, where minimum wages are regulated by law. The majority of previous research seem to point out a negative educational effect of minimum wages. However, this paper finds no evidence that increasing the minimum wage can decrease the high school graduation rate. A possible explanation is that the correlation between the higher employment prospect and educational attainment can create incentives for young individuals to undergo education. This study seems to be the first to investigate the educational effects of minimum wages using internationally comparative data.

A Theory of Intermediation in Supply Chains Based on Inventory Control

Qu, Zhan, Raff, Horst, Schmitt, Nicolas 25 October 2016 (has links)
The paper shows that taking inventory control out of the hands of retailers and assigning it to an intermediary increases the value of a supply chain when demand volatility is high. This is because an intermediary can help solve two incentive problems associated with retailers\' inventory control and thereby improve the intertemporal allocation of inventory. Adding an intermediary as a new link in a supply chain is also shown to reduce total inventory, to make shipments from the manufacturer less frequent and more variable in size, as well as to reduce social welfare.

The Game of Drones : A comparative study on the use of Uninhabited Aircraft Systems

Ribas Teixeira, Arthur January 2022 (has links)
Uninhabited Aircraft Systems (UAS), as a relatively novel technology, was always seen as a tool available and utilized only by rich and developed states. But thanks to globalizations and the fast proliferation of commercially available drones, this platform has already been used by smaller states and also non-state groups, giving them possibilities never seen before. Yet, there is little research on how and why these new actors use UAS to claim their cause. The research question to guide this thesis is how and why do non-state armed groups differ from states when using Uninhabited Aircraft Systems in their military operations? The thesis uses a demand- and supply-side theory, adapted for the proliferation of drones to help answer that question. This theory is tested in a multiple case study involving the United States as a state and the Houthis as a non-state group during the Yemeni crisis, from 2011 to 2022. Through a structured, focused comparison between the cases, indicators from the demand- and supply-side models were used to understand the differences in drone use between different actors. The main findings are that states and non-state armed groups differ in their use of UAS mainly because they have different boundaries (legal and technological), but also for the symbol and status that this platform carries. Finally, it was seen that the theory is not only able to clarify the trends on proliferation, but also the why actors use UAS, with few remarks, but with a need to test it further.

Critical assessment of live music performances in creating a memorable experience :|ba demand and supply perspective / Bianca Manners

Manners, Bianca January 2013 (has links)
The live music performance industry is growing tremendously in South Africa, with more and more international artists performing on our shores year after year. Competition is growing and various companies are beginning to identify this as a business opportunity to make money. However, managing live music performances is a complex task which involves managing various aspects (critical success factors) of the event in order to ensure that it is a success. Apart from this, visitors attend these performances hoping that their expectations will be exceeded and the performance is something which can be treasured and is worth remembering once everything is over. This is referred to as a memorable experience. In order to ensure a memorable visitor experience, it is essential for managers to be aware of what the visitors regard as important critical success factors. These are aspects that management can control and improve. Thus, the critical success factors should be implemented effectively in order to ensure that the event is memorable for visitors attending the live music performance. While various critical success factors are familiar to event organisers, they differ from event to event. Thus, the critical success factors of one event cannot be implemented at another with the same expectation of success. This is due to the heterogeneous groups of people who attend these events and who cannot be regarded as being the same, as each individual will have different expectations of the same event. Therefore, it is also important for the managers of live music performances to determine how the visitors to the different genre events regard the various critical success factors that are vital for a memorable experience. This is significant, as various music genres attract different attendees who each have their own expectations of a music genre and which may differ from those of visitors to other music genres. For example, the expectations for a memorable experience of individuals attending a classical live music performance will differ from individuals attending a rock or pop live music performance. In addition, it is also important for management to compare those critical success factors identified by the visitors to their own ideas of what is important for a successful event in order to identify any shortcomings. Thus, it was expedient to seek answers to the questions of what visitors to live music performances regard as important critical success factors as well as what the managers consider to be important for a memorable experience. Therefore, the purpose of this study was to determine the critical success factors for managing a memorable visitor experience at live music performances from both the demand and supply sides. The said factors were subsequently compared in order to establish whether any shortcomings exist. This thesis comprises three articles. Firstly, the research was conducted from a demand (visitors) side. Thus, the aim of Chapter 3 was to determine what attendees at live music performances regard as being critical success factors for different music genres so as to enhance memorable visitor experiences. Surveys were conducted at various genres of live music performances which included classical music (Il Divo), R&B (Usher), rock (Sting), blues (Michael Buble), pop (Roxette) and Afrikaans music (Steve Hofmeyr). A total of 4 110 questionnaires were administered and a general profile of the visitors in terms of the different genres was compiled. A factor analysis was subsequently performed in order to determine the critical success factors for all six genres. Thereafter, an Analysis of variance (ANOVA) was applied in order to compare the critical success factors of the various genres with one another. The results indicated significant statistical differences amongst the different music genres with regard to that which the visitors to the different live music performances regard as being important for a memorable visitor experience. Secondly, the research was conducted from a supply (managers) side and the objective of Chapter 4 was to determine what the managers consider to be important critical success factors in ensuring a memorable visitor experience at a live music performance. A qualitative research method, by means of interviews, was used to obtain the relevant information from the selected participants. All the data collected in the process were transcribed into text and presented in a narrative form. The six step method formulated by Cresswell (2009:185-189) for data analysis and interpretation was used to analyse the data. Four major themes emerged from the analysis where each theme was differentiated in terms of various categories and subcategories. This process contributed greatly towards gaining detailed information regarding the main purpose of organising a live music performance; identifying the aspects that managers consider to be important when organising a live music performance and those aspects that are important in pre-, during- and post-event planning phases as well as how managers define a memorable experience. Lastly, in Chapter 5 a comparison was performed between the demand and supply sides of live music performances in order to establish whether any differences exist amongst the aspects that management consider to be important compared to the critical success factors that the visitors regard as being important to achieve a memorable visitor experience. Both qualitative (supply side) and quantitative (demand side) research methods were implemented in this research. The results of the critical success factors drawn from the first and second articles were used to conduct this research. The results of both the demand and supply sides were subsequently compared with one another where significant differences had been identified. This was the first time that research was conducted from both the demand and supply sides within the live music performance environment. The results of this research contribute greatly to literature and to the music industry. In addition, this was also the first time that both a qualitative and a quantitative research method were applied in research conducted at live music performances and which were subsequently compared with one another. Determining the differences between the critical success factors identified contributes towards event specific education and information for current as well as future live music performance managers. Therefore, results of this research can be employed to educate and inform current and future managers in the live music performance industry regarding important aspects relating to the enhancement of the important critical success factors that contribute to a memorable experience when individuals attend a live music performance. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

Un modello econometrico regionale "globale" per il mercato del lavoro italiano / A "Global" Regional Econometric Model in the Italian Labour Market

BARBIERI, LAURA 23 May 2008 (has links)
Partendo dalla constatazione della sempre maggiore complessità del contesto economico e sociale nazionale ed internazionale, imputabile da un lato al processo di integrazione economico e monetario europeo, e dall'altro alla progressiva decentralizzazione dei poteri a livello regionale, la tesi intende proporsi come uno strumento analitico di supporto al decisore. A tal fine, in base a dati annui di fonte ISTAT-SVIMEZ per il periodo 1970-2003, viene sviluppato un modello econometrico regionale 'globale' per il mercato del lavoro italiano, estendendo un precedente modello mono-regionale proposto da Baussola (2003), ad un contesto pluri-regionale. Il modello conduce non solo a rappresentare soddisfacentemente i mercati regionali italiani, ma opera altresì efficacemente nel ricostruire i valori delle variabili a livello nazionale. Il modello si conferma robusto ed efficace nel rappresentare le realtà regionali, anche nell'ottica di analisi propria dell'econometria delle serie storiche. / The starting point of this thesis is the remark that recent decades have been characterized by a rising complexity in the economic and political context both at the national and international level. This is due both to the European economic and monetary integration process and to the regional decentralisation process. With the aim of providing a useful tool of analysis for the decision-maker,. a 'global' regional model for the Italian labour market has been constructed on the basis of annual data from ISTAT-SVIMEZ over the 1970-2003 period. This model could be viewed as an extension to a multi-regional framework of the previous one-region model developed by Baussola (2003). The model shows good performance not only in representing regional labour market specificities, but also in reproducing national variable values. It is also robust and effective in a time-series context.

Regionale Charakteristik der Nachfrage und des Angebots an Wohnungen in der Ukraine seit dem Jahr 2000:

Ortner, Andreas 24 June 2015 (has links) (PDF)
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.
