31	Reálná a cenová konvergence České republiky a nových členských států Evropské unie / Real and price convergence of the Czech Republic and the new Member states of the European Union Nováková, Veronika January 2015 (has links) This Thesis deals with the convergence of European states and identifies the influence of the European union enlargement in 2014 on the course of convergence. Both real and price convergences are analyzed by using beta convergence and sigma convergence concepts. The Balassa Samuelson effect is tested as well. The Balassa Samuelson effect explains the existence of price convergence and also indicates the relationship between real and price variables. The existence of real and price convergence was verified for the whole period from 1995 to 2013. During 2004 the integration of European states was strengthened, which was significant for real convergence because the speed of convergence was positively influenced. As for the price convergence, the year 2004 was insignificant as the break point. Despite a similar course of both convergences, price convergence was more affected by the crisis in 2008. The presence of Balassa Samuelson effect was confirmed. Despite the complications during intensity measurement, caused by problematic dividing into tradable and non tradable sectors, corresponding values are realistic.

33	租稅混合對租稅逃漏的影響－兼論公共財最適提供法則 / The Tax-Mix Effects on Tax Evasion and The Optimal Rule of Public Good Provision 夏美業 Unknown Date (has links) 本篇以政府採行租稅混合為為核心，在產市勞市交互運作影響下，作地下經濟與地上經濟的兩部門一般均衡分析。我們不僅從租稅收入面探討租稅逃漏，更將觸角延伸至至政府支出面。最後，以這樣架構下分析公共財的Samuelson條件。　　本文大致上可分為兩部分，第一部分以數學比較靜態及數值分析，討論政府的租稅工具－直接稅和間接稅，公共財，懲罰工具－逃漏直接稅和間接稅的懲罰稅率，等政策工具對經濟變數尤其是逃漏的影響。第二部分，我們承襲Usher(1986)，討論有租稅逃漏時對政府採行租稅混合稅制下公共財的提供成本，亦即Samuelson條件。　　第一部分，我們發現：所得稅率和消費稅率提高均使地下勞工比例上升。透過租稅混合效果下，對地下對黑市勞工比例影響不確定。可是隨著消費稅期望懲罰率逐漸提高，所得稅率比消費稅率對地下勞工比例的影響來得大，故租稅混合在此情況下抑制逃漏的效果也將更佳。此外，當原本地下經濟很小及消費稅稅率較高時，則租稅混合抑制逃漏的效果也將不太大。　　消費稅和所得稅期望懲罰率對經濟體系的影響恰與與消費稅和所得稅的影響相反，而且前者相較於後者更能抑制消費稅逃漏，政府提高這兩種懲罰率均能抑制地下勞工比例，然而卻是以降低地上勞工工資為代價。　　公共財對經濟體系的變數影響不確定，但是可發現若公共財對地上經濟生產越具生產力越能抑制地下勞工比例。　　第二部分，我們發現：當查核成本是固定時，在有逃漏情況下，除了得考慮租稅混合稅制下的扭曲成本，亦即租稅混合對稅基的影響，尚得考慮租稅混合稅制下對逃漏的影響。另一方面，公共財對地下勞動比例和消費稅稅基的影響也關係著公共財的提供成本。當查核成本是內生期望懲罰率的函數時，此時查查核成本是非固定的，公共財的提供成本除了受前項的考量因素影響外，尚得考慮租稅混合稅制及公共財對淨查核成本的影響。租稅混合租稅逃漏公共財生產外部性提供成本薩密爾遜條件 Tax Mix Tax Evasion Public Good Production Externality Provison cost Samuelson Rule
34	Macroeconomic aspects of capital flows to small open economies in transition Jönsson, Kristian January 2004 (has links) With the internationalization of financial markets, short-term capital flows to emerging market economies have become an important phenomenon in the world. The papers in this dissertation are concerned with investigating the effects of such flows in the receiving countries. The analysis is cast in a dynamic general equilibrium framework for small open economies. Two of the papers are quantitative investigations of the forces at work in small and relatively poor economies that liberalize trade and capital flows. The common approach of these papers is that of a computational experiment: calibrated simulations constitute a test of whether the models can explain certain dynamics which we observe in the data. The first paper investigates whether a calibrated two-sector neoclassical growth model can explain the magnitudes and the timing of capital flows in the Baltic countries after the fall of the Soviet Union. The results indicate that it can, and that the large and persistent trade deficits which we observe in the data need not be a reason to worry. However, the model also tells us that a reversal of capital flows and large sectoral adjustments lie ahead of the Baltic countries. In the second paper, the focus is on modelling the observed co-movement between consumption and the real exchange rate in Spain, which experienced large capital inflows following the entry into the European Community in 1986. In accordance with episodes of trade liberalization elsewhere, consumption in Spain boomed and the real exchange rate appreciated for several years after 1986. Standard two-sector models with traded and non-traded goods have problems accounting for these facts. The paper explores some mechanisms that can improve the standard modelling framework, and evaluates their quantitative importance in calibrated simulations for Spain. The third paper studies the government’s optimal bailout policy in an environment where sudden stops of capital flows cause financial crises in a small open economy. Real world events, such as the financial crises in the South East Asian countries in 1997, motivate the analysis. Compared to the previous essays, the paper is different in its nature in that it develops a highly stylized environment to analytically study the government’s optimal bailout policy. The paper shows that the government should optimally commit to a policy that only partially protects private debtors against inefficient liquidation. / Diss.

35	Finanční krize a metodologie ekonomie / Financial Crisis and Methodology of Economics Kovanda, Lukáš January 2007 (has links) The thesis deals with significant moments in the relationship between methodology of economics and implications of the financial crisis culminating in 2008 and 2009. Its key insight rests upon the claim that some theoretical concepts developed within mainstream economics do not tackle the reality adequately and contributed in a significant way to the sequence of events leading to the financial crisis. Most of those concepts were introduced in the second half of the 20th century, during a "high tide" of positivistic ideas in the domain of methodology of mainstream economics. Though the same ideas had been already discredited to a large extent by the philosophy of science at the time, mainstream economists did not reflect it satisfactorily. Aside from a historical expose the thesis consists also of an outline of a possible future development of the prevailing form of economic theory; four scenarios of future potential development are presented. In the final parts of the thesis, which are focused more specifically, the author appraises negatively options of the Austrian School as well as post-Keynesianism to influence in a more significant manner the mainstream economics during the post-crisis era.
36	Foreign Exchange Option Valuation under Stochastic Volatility Rafiou, AS January 2009 (has links) >Magister Scientiae - MSc / The case of pricing options under constant volatility has been common practise for decades. Yet market data proves that the volatility is a stochastic phenomenon, this is evident in longer duration instruments in which the volatility of underlying asset is dynamic and unpredictable. The methods of valuing options under stochastic volatility that have been extensively published focus mainly on stock markets and on options written on a single reference asset. This work probes the effect of valuing European call option written on a basket of currencies, under constant volatility and under stochastic volatility models. We apply a family of the stochastic models to investigate the relative performance of option prices. For the valuation of option under constant volatility, we derive a closed form analytic solution which relaxes some of the assumptions in the Black-Scholes model. The problem of two-dimensional random diffusion of exchange rates and volatilities is treated with present value scheme, mean reversion and non-mean reversion stochastic volatility models. A multi-factor Gaussian distribution function is applied on lognormal asset dynamics sampled from a normal distribution which we generate by the Box-Muller method and make inter dependent by Cholesky factor matrix decomposition. Furthermore, a Monte Carlo simulation method is adopted to approximate a general form of numeric solution The historic data considered dates from 31 December 1997 to 30 June 2008. The basket contains ZAR as base currency, USD, GBP, EUR and JPY are foreign currencies.

37	Analýza vývoje cenové konvergence ČR k EU / Analysis of the Price Convergence of CR towards EU Havrlant, David January 2006 (has links) The price level convergence of the transition economies towards the reference economies is linked to the relative price of nontradables, which is explained by the total factor productivity differentials in tradable and nontradable sector. Basic concept is offered by the Balassa Samuelson model and its modifications. Testable equations are derived from these models, and the panel data approach is applied for their estimation. The results indicate faster growth of the relative price of nontradables in transition economies as succession of higher growth rate of the total factor productivity in tradable sector. Hence estimated models confirm the price level convergence of transition economies towards the reference economies. The analyses of price dynamics of the complementary field, i. e. of the tradables, follows, and the basic concept is represented by the rational bubble hypothesis. The stress is putted on the impact of the word prices on the price levels of the Czech Republic. After a cointegration analysis of the time series is carried out, the influence of the word prices of tradable commodities is estimated within a vector error correction model and regression analysis. This cost factors analysis is afterwards related to the export dynamics of the Czech Republic, and models suitable for quantitative analysis of export dynamics as well as its prediction based on vector error correction model and regression analysis are evaluated. Their forecasting ability is assessed within a simulation of ex-post forecasts and a root mean squared error. The aim is to consider the relationship between the price levels and the export dynamics, for the relation of both variables evaluated within the Granger causality seems to be less straightforward then the standard export equations suggest, and the estimated equations confirm significant influence of the export dynamics on the price level.
38	The Social Construction of Economic Man: The Genesis, Spread, Impact and Institutionalisation of Economic Ideas Mackinnon, Lauchlan A. K. Unknown Date (has links) The present thesis is concerned with the genesis, diffusion, impact and institutionalisation of economic ideas. Despite Keynes's oft-cited comments to the effect that 'the ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood'(Keynes 1936: 383), and the highly visible impact of economic ideas (for example Keynesian economics, Monetarism, or economic ideas regarding deregulation and antitrust issues) on the economic system, economists have done little to systematically explore the spread and impact of economic ideas. In fact, with only a few notable exceptions, the majority of scholarly work concerning the spread and impact of economic ideas has been developed outside of the economics literature, for example in the political institutionalist literature in the social sciences. The present thesis addresses the current lack of attention to the spread and impact of economic ideas by economists by drawing on the political institutionalist, sociological, and psychology of creativity literatures to develop a framework in which the genesis, spread, impact and institutionalisation of economic ideas may be understood. To articulate the dissemination and impact of economic ideas within economics, I consider as a case study the evolution of economists' conception of the economic agent - "homo oeconomicus." I argue that the intellectual milieu or paradigm of economics is 'socially constructed' in a specific sense, namely: (i) economic ideas are created or modified by particular individuals; (ii) economic ideas are disseminated (iii) certain economic ideas are accepted by economists and (iv) economic ideas become institutionalised into the paradigm or milieu of economics. Economic ideas are, of course, disseminated not only within economics to fellow economists, but are also disseminated externally to economic policy makers and business leaders who can - and often do - take economic ideas into account when formulating policy and building economic institutions. Important economic institutions are thereby socially constructed, in the general sense proposed by Berger and Luckmann (1966). But how exactly do economic ideas enter into this process of social construction of economic institutions? Drawing from and building on structure/agency theory (e.g. Berger and Luckmann 1966; Bourdieu 1977; Bhaskar 1979/1998, 1989; Bourdieu 1990; Lawson 1997, 2003) in the wider social sciences, I provide a framework for understanding how economic ideas enter into the process of social construction of economic institutions. Finally, I take up a methodological question: if economic ideas are disseminated, and if economic ideas have a real and constitutive impact on the economic system being modelled, does 'economic science' then accurately and objectively model an independently existing economic reality, unchanged by economic theory, or does economic theory have an interdependent and 'reflexive' relationship with economic reality, as economic reality co-exists with, is shaped by, and also shapes economic theory? I argue the latter, and consider the implications for evaluating in what sense economic science is, in fact, a science in the classical sense. The thesis makes original contributions to understanding the genesis of economic ideas in the psychological creative work processes of economists; understanding the ontological location of economic ideas in the economic system; articulating the social construction of economic ideas; and highlighting the importance of the spread of economic ideas to economic practice and economic methodology. 410401 Design Theory 349901 Political Economy 370000 Studies in Human Society 340302 History of Economic Thought 349900 Other Economics 410402 Design Innovation 360201 Public Policy 360000 Policy and Political Science 380100 Psychology 360100 Political Science 360200 Policy and Administration 370101 Social Theory 370102 Social Policy and Planning 340100 Economic Theory genesis spread diffusion impact institutionalisation economic ideas idea ideation psychology of creativity Wallas Wertheimer stage model productive thinking creative creativity process economic economics sociology social methodology methodological self-altering self-fulfilling self-denying prophecy belief reflexive reflexivity institution institutionalise institutionalised social construction Berger Luckmann Bhaskar critical realism Lawson Bordieu habitus field spread impact ideation ideational structure social structure action creativity creative economists sociology philosophy of science homo economicus homo oeconomicus economic man economic agent rational economic man man lucas critique Goodhart's law Keynes Marx Mill Hayek Hicks Samuelson Walras Jevons Arrow Debreu Samuelson Merton sociology of economics sociology of scientific knowledge SSK Holton prediction control reflexive prediction reflexivity Whitley Mackie canonization Henshel Grunberg Modigliani Morgenstern Lucas Muth Simon Blyth Hall Sikkink Hira Hood institutionalize institutionalized socialise socialisation internalise internalisation internalization socialization behaviour behavior Thomas theorem expectations stage model productive thinking evolution
