This book seeks to reinvigorate debates on the growing forces influencing China’s social and economic evolution. It draws attention to several neglected areas in the discussion of China’s rapid economic expansion, such as unbalanced growth, mass internal migration, international labour flows, and disparities in access to education, public health, and housing.China’s rapid economic development has attracted the interest of many scholars following its emergence as the world’s second largest economy and stimulated research into the underlying factors that have made this development unique. In advancing research, the chapters included in this edited book help with refining our understanding of the forces that have been driving China’s social- economic, political, institutional and technological developments, addressing the related issues, thus, advancing the social economic literature within the China context. This book serves the interests of scholars who seek to understand more fully the development of China as well as of other emerging economies.One of the chapters in this volume was originally published in the Review of Evolutionary Political Economy. Other chapters were originally published in the Forum for Social Economics.

Seminar paper from the year 2008 in the subject Business economics - Investment and Finance, grade: 95.00%, , language: English, abstract: This project examines in the first part the covered and uncovered interest parity between US dollar and Swiss Franc. We present simple summary statistics, unit root tests, deviations from covered interest parity, regression analysis, threshold autoregression and exponential transition autoregression. Then we present the uncovered interest parity and, as in the case of covered interest parity, we apply some tests to examine if it's valid. We apply Johansen cointegration tests between spot and forward rates, but also between forward premia and interest rates differentials and we test if there is a cointegration equation and we estimate the vector error correction model. After this procedure we present the impulse responses. Next we test if there is a threshold cointegration relation between the above variables. Finally in the last section we apply a dynamic OLS (DOLS) estimation with Newey-West HAC standard errors. In the second part the purchasing power parity (PPP) hypothesis is examined with a similar methodology followed, where additionally we present a long span study, unit root tests allowing for structural breaks in data, panel unit root tests as also Markov switching regime autoregressive model is examined in the category of the non linear models

Seminar paper from the year 2008 in the subject Computer Science - Commercial Information Technology, grade: 90.0%, , language: English, abstract: In this paper we examine the calendar anomalies in the stock market index of Athens. Specifically we examine the day of the week and the month of the year effects, where we expect negative or lower returns on Monday and the highest average returns on Friday for the day of the week effect and the higher average returns in January, concerning the January effect. For the period we examine we found insignificant returns on Monday, but significant positive and higher average returns on Friday. Also our results are consistent with the literature for the month of the year effect, where we find the highest average returns in January. Furthermore we estimate with ordinary least squares (OLS) and symmetric and asymmetric Generalized Autoregressive Conditional Heteroskedasticity (GARCH) rolling regressions and we conclude that the week day returns are not constant through the time period we examine but are changed. Specifically, while in the first half-period of the rolling regression there are negative returns on Mondays so we observe the day of the week effecting, in the last half-period of the rolling regression Friday presents the highest returns, but the lowest returns are reported on Tuesday and not on Monday, indicating a change shift in the pattern of the day of the week effect. Full programming routines of rolling regressions in EVIEWS and MATLAB software are described.

Seminar paper from the year 2007 in the subject Business economics - Investment and Finance, grade: 90.0%, , language: English, abstract: This paper examines the estimating and forecasting performance of the different and various Generalized Autoregressive Conditional Heteroscedasticity-GARCH's models in relation to Capital Asste Pricing Model (CAPM) model. We apply the CAPM model with ordinary least squares (OLS) method to investigate if an ARCH (Autoregressive Conditional Heteroscedasticity) is presented and we are trying to decide and to analyze which GARCH model is the most appropriate and the best fitted for the financial time series that we have chosen. We apply CAPM model in the financial time series of the share prices of Technology-Software Sector in Athens Exchange stock market for the period January 1st of 2002 to October 30th of 2007 for the enterprises "e;Unibrain"e; "e;MLS Informatics"e; and "e;Dionic"e; respectively , from April 2nd of 2002 to 30th October of 2007 for the enterprise "e;Compucon"e;, from August 2nd of 2002 to 30th October of 2007 for the enterprise "e;Centric"e;, and finally from February 2nd of 2004 to 30th October of 2007 for the enterprise "e;Ilyda"e;. Additionally, we apply roiling regressions, where the full programming routines in EVIEWS and MATLAB are described detailed. We conclude that the slope coefficient of CAPM model is not constant through the time period of rolling regressions we apply. In the final part we examine a simple Arbitrage Pricing Theory (APT) model.

Master's Thesis from the year 2009 in the subject Business economics - Business Management, Corporate Governance, grade: 100.0%, Hellenic Open University (School of Science and Technology), language: English, abstract: The present dissertation work has as the main purpose the reliability and maintenance analysis in unit production of Ammonia in Industry of phosphoric fertilizers production residing in New Karbali- Kavala. The dissertation is constituted by eight chapters. In the first chapter that constitutes the introduction are reported the purpose of the dissertation, the source of data, the structure and the methodological approach that will be followed. In the second chapter is reported concisely the theory of reliability and the mathematical approach for its analysis. Similarly in the third chapter the significance and the theory of maintenance and the basic quantitative measures for the approach are presented. In the fourth chapter are presented concisely previous empirical researches and studies that have been written in the reliability and maintenance theory and applications for various cases and is various branches. In the fifth chapter is presented a description for the structure and the operation of Ammonia unit production and its sub systems, by which it is constituted. In the sixth chapter are presented the numerical data, which are used for the application of the statistical analysis of reliability. The parametric Weibull distribution is selected, the finding of success and failure probability in each subsystem separately and in whole unit as well are reported. Also in the same chapter a Pareto analysis is been made for the of failure type frequency in order to be explicit which type of failure lead to dysfunction and participate at a higher percentage in the production loss. Then a bootstrapping simulation is applied in order to confirm the results that have been found initially. Next, the methodology of neural networks is proposed, which present a great success and augmentative tendency in the application in many sciences and specifically three models are presents and applied. Finally, we apply a neuro-fuzzy model to estimate the reliability of Ammonia production unit. In the seventh chapter are presented the numerical data on the for maintenance analysis. In the eighth chapter Cox proportional hazard models are analyzed and estimated for the preventive maintenance. In the ninth chapter predictive maintenance is analyzed and specifically multinomial Logit models are estimated to predict the probabilities for failure kinds. In the last chapter the conclusions are presented.

Seminar paper from the year 2008 in the subject Business economics - Investment and Finance, grade: 100%, , course: Money and Capital Market Analysis, language: English, abstract: This paper presents the classic-static beta values and beta values estimated by an asymmetric beta model. In asymmetric model we have the possibility to estimate the upside and downside betas, while in the static model we are not able to work it out. We will estimate the static and asymmetric betas of two stocks in France Exchange stock market, Michelin and Tf1. So the data consists of daily returns of France Exchange stock market index CAC-40 and the above two stocks , during the period June 2nd of 2000 to May 17th of 2004. Actually this paper examines the estimation of betas under bull and bear market conditions. Asymmetries are of substantial economic importance for an investor who has symmetric beliefs, so he must switch his beliefs in an asymmetry one, where this is necessary.
