This dissertation consists of three independent essays. The first essay, “Long Waves and Short Cycles in a Model of Endogenous Financial Fragility,” presents a stock flow consistent macroeconomic model in which financial fragility in firm and household sectors evolves endogenously through the interaction between real and financial sectors. Changes in firms’ and households’ financial practices produce long waves. The Hopf bifurcation theorem is applied to clarify the conditions for the existence of limit cycles, and simulations illustrate stable limit cycles. The long waves are characterized by periodic economic crises following long expansions. Short cycles, generated by the interaction between effective demand and labor market dynamics, fluctuate around the long waves. The second essay,“Macroeconomic Implications of Financialization,” examines macroeconomic effects of changes in firms’ financial behavior (retention policy, equity financing, debt financing), and household saving and portfolio decisions using models that pay explicit attention to financial stock-flow relations. Unlike the first essay, the second essay focuses on the effects of financial change on steady growth path. The results are insensitive to the precise specification of household saving behavior but depend critically on the labor market assumptions (labor-constrained vs dual) and the specification of the investment function (Harrodian vs stagnationist). The last essay, “Finance, Sectoral Structure and the Big Push,” studies the role of finance in the presence of investment complementarities using a big push model. Due to complementarities between different investment projects, simultaneous industrialization of many sectors (big push) may be needed for an underdeveloped economy to escape from an underdevelopment trap. Such simultaneous industrialization requires costly coordination by a third party, such as the government. Some recent papers show that private banks with significant market power may also solve the problem of coordination failure. We show that private coordination may not work since even large private banks may find it more profitable to finance firms in the traditional sector than in the modern sector.

In this thesis, I argue for a move from the preoccupation with the obvious (crude and quantifiable impacts), towards critically examining the subtle (less than obvious impacts), which will allow us to deal with adversities (the likes of HIV and AIDS) in the most effective ways. The thesis adopts the summative governance framework to demonstrate how our preoccupation with the quantifiable impacts shrouds our intellectual and practical ability to deal with the subtle impacts of AIDS. Governance is hypothesised to emerge amidst turbulent, unpredictable, messy, complex and dynamic path conditions predicated upon certain orders of criticality, including but not limited to the process of knowledge formation, retention and transfer. The thesis suggests that the evolution of governance from nascent to fully institutionalised mechanisms of control is in itself a product of the evolution of knowledge. Notwithstanding, HIV and AIDS constrain the emergence of governance through impacting the process of knowledge formation, retention and transfer. Resultantly, these impacts are not merely additive and isolated to the sectoral governances, but are summative, intergenerational and structured, and potentially endanger the fundamental systems of governance. The pre and post independence induced vulnerabilities of Namibia are presented to demonstrate that the country is an engrossing, but yet a perilous mix of the past and the present. Whilst Namibia aspires for a democratic, non-racial, progressive society, the thesis demonstrates that due to constraints engendered by HIV and AIDS this proceeds on terms and conditions that by no means guarantee a happy outcome.

The pleasure of humans seems to be often found in crossing boundaries. However, crossing legal boundaries provides a compliance violation that can lead to serious consequences – especially in the highly regulated German healthcare system. Due to the large number of regulations, economic competition is strictly limited in the German healthcare sector creating a considerable conflict between economic pressure, entrepreneurial visions and legal requirements. The identification of clear boundaries, the exploration of creative leeway and the crossing of compliance-related prohibition zones is oftentimes difficult due to the considerable legal 'grey area' between black and white, which has not yet been fully clarified by case law. The use of these grey areas as well as the crossing of permissible boundaries takes place in various forms in reality. Cooperations in which a physician crosses the so-called sectoral boundary (Sektorengrenze) in his own person, for example as an affiliated or fee-based physician (Beleg- oder Honorararzt), and provides both inpatient (stationäre) and outpatient (ambulante) medical services, are of particular relevance. In this context, this article is intended to provide an overview of the most commonly used forms of combined outpatient and inpatient activities (intersectoral activities) by the same person and to highlight the associated compliance issues.

[Truncated abstract] The Asian Financial Crisis was a wake-up call to the South Korean economy that a change to its economic structure was needed. Prior to the Crisis, South Korea enjoyed healthy economic growth and low unemployment. With the onset of the Crisis, Korea experienced severe recession. Unemployment levels soared and turnover in the labour market became commonplace. The Korean government enacted a series of policies and succeeded in combating unemployment in the short-term. To the present time, unemployment levels have been lowered, albeit with job instability and insecurity. A more effective longer-term solution is needed to increase the resilience of this NIE. The role of inter-sector labour mobility as a policy tool to combat unemployment using the relevant determinants of mobility has not been explored in Korea (Asia), although it has been debated at length in the West since the 1980s. Part of the reason for this lies in the lack of longitudinal data to facilitate appropriate research. Recently, such data have been made available by the Korean Labour Institute (KLI). This thesis extends research into the labour mobility-unemployment relationship to South Korea. The priority is to establish whether a mobility-unemployment relationship exists in Korea, and to obtain a thorough understanding of the factors affecting sectoral mobility in this country in order to facilitate the crafting of potential tools for addressing the unemployment problem. The thesis is organised into two parts. ... The main finding is that whilst the monetary variables and worker/industry characteristics impact male and female mobility differently, sectoral unemployment and sectoral shock affect male and female mobility similarly. The thesis is summarised and some policy measures provided in the sypnosis. It is argued that the 'new' mobility-unemployment phenomenon appears to have emerged in Korea after the Crisis, whereas it had been a feature of Western economies in much earlier time periods. Traditional monetary and fiscal policies are inadequate when it comes to combating unemployment in the presence of this mobility-unemployment phenomenon. A combination of macro-policies, given the relevance of the ADH, and micro-policies, given the validity of the SSH, is required. The multi-dimensional nature of mobility implies that the micro policies to control or reduce mobility rates using the relevant variables (to alleviate unemployment) should cover measures related to monetary wages, labour market groups and sector performance. The sypnosis notes a dearth of Asian studies on sectoral mobility, possibly due to the lack of longitudinal data. The collection of quality longitudinal data for other Asian countries, so that research along the lines conducted in the thesis could be undertaken for other NIEs, was seen as being of vital importance. With such data, the standard of research on Asian economies can be at par with that of the Western countries, and the apparently considerable potential benefits of microeconomic policies via sectoral mobility for Asia could be realised.

The transition from communism to capitalism at the end of the last century was one of the most significant events in the world economy since industrialization. During the latter part of the 1980s, people the Central and Eastern European countries and former Soviet Republics opted for a change from highly distorted command economic system to a market driven economic system. Privatization and liberalization policies led to major changes in the commodity mix and volume of agricultural production, consumption and trade. However, the changes and the impacts varied among countries as they followed different transition strategies. This study investigated the impact of market liberalization on the agricultural sector, as well as how the inter-sectoral linkages among the agricultural, industrial and service sectors responded in Poland, Romania, Bulgaria and Hungary using time-series analysis. The study estimated an econometric model that incorporates the linkages among the sectors using a Vector Error Correction Model. The procedure identified long-run and short-run relationships for each country. The results showed that a sector can have a negative linkage to other sectors in the short-run; however, that does not mean that the linkage will be negative in the long-run. Impulse response functions were constructed to determine how a system reacts to a shock in one of the endogenous variable in a model. The study explored how a shock in the agricultural sector was absorbed by the other sectors in the economy, and how a shock in the other sectors was absorbed by the agricultural sector, in all four countries. The responses reflected how the variables are interrelated within a country, and how the shocks are transferred through different linkages over a long period of time. Such dynamic analysis was used to identify the total impacts of different policy alternatives.

WTO爭端解決小組於二００四年三月底針對「美國控告安地瓜禁止線上賭博案」（WT/285）乙案提出保密的期中報告。蕞爾小國安地瓜巴布達擊敗美國獲得勝訴的判決。期中報告指出，美國對於安地瓜線上博奕服務業者所提供之跨境線上博奕服務，在「市場進入」及「國民待遇」未予開放，違反了其於「服務貿易貿易總協定」所為之承諾。 此期中報告對於服務貿易有特殊之意義。不只因為本案為WTO爭端解決程序中第一個涉及網際網路的案子，本案更是第一個關於服務貿易分類之案例。本案爭點在於安地瓜之線上博奕業者是否得對美國境內之消費者提供線上博奕服務。 安地瓜認為，根據「聯合國中央產品暫行分類標準」（CPC pro.）及「服務部門分類表」（W/120），美國在其承諾表10.D確承諾跨境線上博奕服務之開放，然美國之國內規章對境外所提供之線上博奕服務卻造成全面禁止之效果，故已違反其所為之承諾。然而美國則認為秘書處所提出之W/120文件並不具有法律拘束力，因此美國承諾表並不受CPC分類之限制。 W/120文件在解釋承諾表時的法律地位究竟為何，為本案最重要的爭點，本論文將深入探討之。 / Late March in 2004, WTO panel released a confidential report of the WTO dispute” United States– Measures Affecting the Cross-Border Supply of Gambling and Betting”（WT/285）.The finding is that the tiny nation of Antigua and Barbuda beat the United States that the United States violates its commitments under the General Agreement on Trade in Service(GATS) by not providing market access and/or national treatment under GATS to on-line cross-border gambling service providers licensed by Antigua and Barbuda. The panel report has significant ramification for trade in service. The reason is that this panel decision is not only the first one on Internet-related dispute, but also the first one concerning the general service issues- service classification. Antigua asserted that United States has made a GATS commitment for gambling and betting service within Sector 10.D of U.S schedule corresponding Provisional United Nations Central Production Classification (CPC) and the Service Sectoral Classification List(MTN.GNS/W/120). At issue in this case is the provision of internet gambling service to customers in the United States from operators located in Antigua and Barbuda. Antigua and Barbuda argued that the domestic regulation of United States has made total prohibition on the supply of gambling and betting service from outside the United States. However, United States responded that the document W/120 provided by the GATT Secretariat is not legally binding so it’s schedule is not bound by the category of CPC. It means that the United States has no responsibility to allow on-line cress-border gambling service. This thesis has a deeply discussion on the legal status and value of W/120 in interpreting GATS schedules which is the most important issue in this case.

The Canterbury region of New Zealand experienced four earthquakes greater than MW 6.0 between September 2010 and December 2011. This study employs system dynamics as well as hazard, recovery and organisational literature and brings together data collected via surveys, case studies and interviews with organisations affected by the earthquakes. This is to show how systemic interactions and interdependencies within and between industry and geographic sectors affect their recovery post-disaster. The industry sectors in the study are: construction for its role in the rebuild, information and communication technology which is a regional high-growth industry, trucking for logistics, critical infrastructure, fast moving consumer goods (e.g. supermarkets) and hospitality to track recovery through non-discretionary and discretionary spend respectively. Also in the study are three urban centres including the region’s largest Central Business District, which has been inaccessible since the earthquake of 22 February 2011 to the time of writing in February 2013. This work also highlights how earthquake effects propagated between sectors and how sectors collaborated to mitigate difficulties such as product demand instability. Other interacting factors are identified that influence the recovery trajectories of the different industry sectors. These are resource availability, insurance payments, aid from central government, and timely and quality recovery information. This work demonstrates that in recovering from disaster it is crucial for organisations to identify what interacting factors could affect their operations. Also of importance are efforts to reduce the organisation’s vulnerability and increase their resilience to future crises and in day-to-day operations. Lastly, the multi-disciplinary approach to understanding the recovery and resilience of organisations and industry sectors after disaster, leads to a better understanding of effects as well as more effective recovery policy.

In this study an attempt has been made to explore the role of technology transfer in the economic growth of Iraq, through the change in the technology itself for the period 1960-1978. For this purpose the economy was disaggregated into seven sectors. The experience of developed countries has shown that technical change is one of the most important factors of economic growth alongside, or even overshadowing, such factors as labour and capital. In the light of technology transfer, developing countries have the advantage of introducing high levels of advancement of knowledge which can be used to induce domestic technical change at later stages. Technical change is normally defined as a shift in the production function, and for this reason two forms of production function were estimated and tested, i. e. the constant elasticity of substitution and the Cobb-Douglas function. Also two specifications (constant and variable) were assigned to technical change. To validate the use of these, statistical tests were conducted to establish the optimum fit. Then the selected form was used to simulate output levels for comparison with actual figures. The techniques used for estimation are both linear and non-linear. Data used are time series in real terms of capital stock and output, as well as number of persons employed. Furthermore in order to judge the importance of technical change to the growth of output on aggregate and sectoral levels, as regards economic growth, comparisons were drawn with existing data from other developed and developing countries, including centrally planned economies.

[pt] Nesse trabalho usamos um modelo DSGE de preços rígidos para estudar os efeitos de uma regra monetária que reage a mudanças no núcleo de inflação ao invés da inflação cheia. Começamos discutindo as dificuldades de inclusão das medidas de núcleo em nosso modelo DSGE e apresentamos uma solução viável. Com base em uma versão estilizada do modelo, mostramos que as volatilidades do núcleo e inflação cheia podem variar bastante dependendo da regra monetária adotada. Os resultados são interpretados em função da contribuição de choques agregados e setoriais na variância do núcleo e inflação cheia. A seguir conduzimos um exercício quantitativo com foco na Austrália. O interesse no último deriva da nossa percepção de que a autoridade monetária australiana começou a responder aos movimentos do núcleo de inflação por volta de 2007. Entretanto, nosso modelo calibrado não é capaz de reproduzir o comportamentos das medidas de inflação depois de 2007. / [en] We use a multi-sector sticky-price DSGE model to study the effects of a monetary rule that responds to changes in the underlying measure of inflation as opposed to headline inflation. We discuss the difficulties of including the underlying measure in our DSGE model and present a feasible solution. Using a stylized version of the model, we show that headline/underlying volatilities can experience significant changes under a policy rule that reacts to the underlying measure. The results are interpreted on the basis of the relevance of aggregate and sectoral shocks to headline and underlying inflation. We then conduct a quantitative exercise focused on Australia. The interest in the latter comes from our belief that monetary authority actually started to react to underlying inflation around 2007. We find that the calibrated model is not able to reproduce the behavior of headline/underlying inflation after 2007.
