Are Windfalls a Curse? A Non-Representative Agent Model of the Current Account and Fiscal Policy
Full text linkIn several countries temporary terms of trade improvements have led to a deterioration of the current account. Furthermore, many of these countries failed to attain greater post-boom growth rates. The point we make is that the structure of the fiscal process is critical in determining outcomes. If fiscal control is unitary, then the consumption-smoothing effect is operative, and representative-agent models of the current account have predictive power. However, if control is divided among several fiscal claimants, a voracity effect appears which counteracts the consumption-smoothing effect, leading to a deterioration of the current account in response to a positive shock. We model the interaction among fiscal claimants as a dynamic game, and show that in equilibrium aggregate appropriation increases more than the windfall itself. This results in a deterioration of the current account. We also show that all the windfall is dissipated, with the country experiencing no increase in its growth rate. Lastly, we analyze the experiences of seven countries which have enjoyed large windfalls.
Forced harmonic-current neutral injection
No full textFull text is available to authenticated members of The University of Auckland only.Harmonic current injection is a technique for reducing the harmonic content in the AC currents produced by converter circuits. The technique makes use of a controlled harmonic current source to inject currents within the AC connection of a converter, such that the harmonic content of the resulting waveforms is reduced. The technique has a history of thirty years. Originally limited by difficulties in producing suitable harmonic currents, advances in power-electronic devices have made possible many new implementations. A novel implementation of harmonic current injection is presented in this thesis, in which the harmonic currents are generated by means of a controlled power-electronic bridge, comprising gate turn-off devices. The implementation is specific to the six-pulse phase-controlled converter, and uses power-electronic and control techniques to produce continuous, controlled neutral currents. The use of gate-tum-off devices allows the generation of arbitrary neutral current waveforms, and makes possible the application to AC motor control. A particular benefit of the current-injection scheme is the possibility of switching the main converter devices at zero current. A theoretical understanding of the technique is developed, to model and predict the operation of circuits employing the described injection system. In particular, the low frequency operation of the system is considered. An experimental current-source rectifier is described, and results obtained from this system are used to confirm the developed theory of operation of the circuit. The theoretical harmonic-current performance of the practical system is found to be nearly ideal. The application of this current-injection system to a Current Source Inverter for induction motor control is investigated, and the operation confirmed with an experimental system. Such a system is of particular interest, as the low-harmonic, low-* currents that are produced result in nearly sinusoidal voltage waveforms at the machine terminals. The high-quality machine currents result in a reduction of harmonic-related torque pulsations in the machine. Unlike a conventional Pulse-Width Modulation drive system, there is no common mode voltage at the machine connection. This is significant in light of recent concerns regarding the premature failure of bearings in machines supplied by conventional high-performance drives. The mechanism for such failures is the build-up of rotor-voltage, due to high 1 dv/d1 common-mode voltages, and the subsequent discharge through the bearing lubricant. Consideration is given to the application of the developed current-injection techniques to voltage-source converters, and the operation of a possible circuit is discussed. Much work remains in the field of implementation of harmonic current injection to the variable speed control of electric machines, and possible directions for future research in this area are given
Numerical Simulation of a Marine Current Turbine in Turbulent Flow
No full textThe copyright of this thesis rests with the author and no quotation from it or information derived from it may be published without the prior written consent of the authorThe marine current turbine (MCT) is an exciting proposition for the extraction of renewable tidal and marine current power. However, the numerical prediction of the performance of the MCT is difficult due to its complex geometry, the surrounding turbulent flow and the free surface. The main purpose of this research is to develop a computational tool for the simulation of a MCT in turbulent flow and in this thesis, the author has modified a 3D Large Eddy Simulation (LES) numerical code to simulate a three blade MCT under a variety of operating conditions based on the Immersed Boundary Method (IBM) and the Conservative Level Set Method (CLS).
The interaction between the solid structure and surrounding fluid is modelled by the immersed boundary method, which the author modified to handle the complex geometrical conditions. The conservative free surface (CLS) scheme was implemented in the original Cgles code to capture the free surface effect.
A series of simulations of turbulent flow in an open channel with different slope conditions were conducted using the modified free surface code. Supercritical flow with Froude number up to 1.94 was simulated and a decrease of the integral constant in the law of the wall has been noticed which matches well with the experimental data.
Further simulations of the marine current turbine in turbulent flow have been carried out for different operating conditions and good match with experimental data was observed for all flow conditions. The effect of waves on the performance of the turbine was also investigated and it has been noticed that this existence will increase the power performance of the turbine due to the increase of free stream velocity
Voucher funds in transitional economies : the Czech and Slovak experience
Full text linkVoucher funds have arisen in the transitional economies of Eastern and Central Europe that have used voucher privatization. These funds collect vouchers from citizens and use them to buy shares in enterprises. In the Czech and Slovak Republics, voucher funds are typically organized as corporations owned by the citizens who contributed their vouchers. Recently, they have also been organized as unit trusts (either open-ended or closed). A management company manages the funds under a contract that specifies the management fee. The management company is typically owned by the initial sponsor of the fund - for example, a bank. Voucher funds can give owners a diversified and professionally managed portfolio. More important, the funds select who sits on an enterprise's governance boards (which oversee management and profitability). Although experience is limited, the funds in these two countries have probably stopped most fraud and self-serving by enterprise mangers and are beginning to encourage the restructuring needed for profitability. A few funds have replaced poorly performing or dishonest managers; more often, because qualified replacements are few, they encourage managers to improve performance. There have been complaints about funds'performance. Some have made unrealistic promises to voucher holders and have appointed poorly qualified members to management boards. There is concern about conflicts of interest in the bank-sponsored funds and excessive control of enterprises. Funds typically lack capital or expertise to undertake restructuring - but few other potential owners are likely to be better qualified. The author examines 27 regulations that have been proposed for funds. Regulations in transitional economies, unlike regulations in most western countries, should encourage funds to play a strong role in corporate governance, he contends, as few potential owners have this ability. Most important, regulations should require that funds disclose information about their operations so their owners can monitor and control fund managers. The regulatory regime, the author says, should discourage monopolies and anticompetitive behavior; create incentives for fund managers to improve fund performance; discourage self-serving or fraudulent behavior by fund managers, and conflicts of interest; and eliminate high-risk investments unacceptable to fund owners. Because there is so little experience with these funds, the regulatory regime should not be unduly restrictive. As problems arise, regulations to deal with them can be added.International Terrorism&Counterterrorism,Economic Adjustment and Lending,Economic Theory&Research,Agricultural Knowledge&Information Systems,Payment Systems&Infrastructure
Modeling of direct tunneling gate current and gate capacitance in deep submicron MOSFETs with high-K dielectric.
No full textScaling down of MOS device dimensions is accompanied by a decrease in gate-oxide thickness and an increase in substrate doping density. When gate oxide thickness becomes less than 2 nm, a substantial current follows through gate-oxide due to direct tunneling. In order to reduce this current, International Technology Roadmap for Semiconductors (ITRS) has suggested replacement of SiO2 gate insulator layer by high-K dielectrics. For a given equivalent oxide thickness (EOT), high-K dielectrics offer greater physical thickness. The direct tunneling (DT) current and the gate capacitance for an inverted n-MOS device with different dielectrics used as gate insulator is studied. Coupled Schrodinger’s and Poisson’s equations are solved self-consistently. Open boundary conditions, taking account the wavefunction tail inside the gate dielectric within the self-consistent loop are used to solve Schrodinger’s equation. DT current increases exponentially with the decrease of conduction band offset for electrons travelling from silicon substrate to dielectric. As general trend of dielectrics is to decrease of conduction band offset with the increase of dielectric constant, use of high-K material as gate insulator results in prominent influence of direct tunneling of carriers on potential profile. Therefore in DT current calculation effect of wavefunction penetration on potential profile is incorporated within self-consistent loop. Results of this simulation is compared with published experimental results and also with the results of the simulation where penetration effect on potential profile is neglected. Results show that neglect of wavefunction penetration effect on potential profile causes underestimation of DT current. A comprehensive analysis of the effect of wavefunction penetration on the gate capacitance of the MOSFETs with high-K dielectrics is also done. Gate capacitance from conventional modeling is found to be independent of dielectric materials for a given EOT. The study reveals that accounting for wavefunction penetration into the gate dielectric causes gate capacitance to vary from material to material for a given EOT. Consequently wavefunction penetration effects must be considered to determine properties of future generation devices where high-K dielectrics will be employed as gate insulator
Law in urban planning and development in East Africa
Full text linkThis study is intended to be a critical examination of the role of
law and the legal profession in Urban pinning and development in the
context of East Africa. It discusses the actual, proposed and possible
functions of law and gives a critical analysis of shortcomings in the
existing law and attitudes towards the planning process. It begins by
discussing the various notions of plmning and development and what these
mean to different groups of people whose work relate to the subject of
planning and development. The first three chapters may be regarded as
setting the scene in that they outline the perspective of the study,
describe the region and its people, deal with the current and future
problems of urbanization, discuss the land tenure systems and evaluate
the processes of acquiring land for urban planning and developnent.
The middle of the thesis, and particularly chapter five examines
the organs, institutions, bureaucracies and. infrastructures of urban
agglomerations. Chapter six deals with land use planning, the aims and
objectives in such planning and how the resulting plans are implemented
and enforced. Of special interest are the functions fulfilled or to be
fulfilled by lawyers in this process. Chapter seven discusses housing
as one of the important objectives of planning and evaluates the agencies
of developzent including foreign investments, building societies and
self-help projects. Included in this chapter are urban rates and rents.
The last chapter is a resume of the study but concentrates on what the
author has called "The Lawyer's 'brief' in Urban Planning and Development".
The theeme of the study has been that planning and development is a
multi-purpose, multi-disciplinary subject in which law must play its part. Consequently, there has been considerable use of materials and authorities
traditionally regarded as "non-legal". One of the fascinating points in
this kind of study is the use and analysis of such materials and authorities
for the purpose of producing a legal discourse
Imagining armies: symbolic dimensions of military power and contested state legitimacy in Iraq, 2003-2014
No full textThis dissertation presents a study of the reconstruction (and subsequent partial disintegration) of the armed forces of Iraq after 2003 as it relates to the larger problematic of state formation and legitimation in contested spaces. The national army, as opposed to paramilitary and police forces, emerged over time as an institution of singular importance in the struggle for Iraq after 2003. Iraq’s new rulers, who otherwise lacked prestige and deeply rooted political support within their own country, sought to appropriate the memory of the old Iraqi Army in order to claim their place as the rightful inheritors of state power. With this inheritance, they claimed, came the legitimate authority to use military force in defense of the new Iraqi state. I traced the development of Iraq’s new armed forces using interviews, archival sources, mass media reports, and photographs, to show how the symbols of Iraq’s militarist past were used by a new regime to bestow a reimagined Iraqi national identity upon military forces raised under foreign occupation and tutelage. My findings challenge the conventional wisdom that state formation in conflict zones of the developing world proceeds directly from a massive military buildup of government forces. Rather, it is the capacity of rulers to credibly sustain claims that their forces represent the nation and the state, which is most important to establishing a monopoly on the legitimate use of physical force within a given territory.Ph.D.Includes bibliographical referencesby Brian E.
