A constructed wetland (0.08 ha) receiving drainage water from a small agricultural catchment (22 ha) with clay soil, was investigated with respect to phosphorus dynamics and retention. The aim was to evaluate the function of the wetland with respect to phosphorus retention, and relate that to gross sedimentation as measured with sediment traps. Hydraulic load and phosphorus retention were estimated for 2003-2010 based on monitoring data. Furthermore, water quality dynamics was studied during three intensive sampling periods of 3-5 days during 2010. For each period, phosphorus retention was calculated and the relationship between flow and phosphorus concentrations analysed. Additionally, the gross sedimentation rate was estimated using sediment traps, and the phosphorus, carbon and nitrogen content analysed. The results suggested that there was no net retention of phosphorus during 2003-2010, except for 04/05. During the intensive sampling periods, release of phosphorus from the wetland mainly occurred during high flow. Sediment analyses showed that settling of inflow particles mostly occurred in the inlet pond, while the sediment found in a shallow vegetated area and outlet pond likely originated from internal processes rather than from the catchment. In fact, the gross sedimentation of phosphorus during April-July and July-August, respectively, exceeded the measured phosphorus inflow. The results showed that short periods with rapid flow increases were crucial for the wetlands function and thus high frequency sampling must be done during these periods. Furthermore, it seems that the particles lost from the catchment during high flows are too small to settle in the wetland.

The main purpose of this study is to investigate relationship between foreign exchange reserves and RMB exchange rate. In order to obtain a precise result, foreign trade situation and GDP are also considered. The monthly data is collected over period 1994 to 2011, and processed through ADF test, Johansen test, and Granger causality test. Final results indicate that there is a long-term equilibrium relationship existing between foreign exchange reserves and RMB exchange rate. Moreover, any changes of foreign exchange reserves would lead to the fluctuation of RMB exchange rate but not vice versa. At last, the dummy variables are added into regression model to test influence from the reform of RMB exchange rate regime. Results suggest that regime reform not only increase flexibility of RMB exchange rate, but also slow down the accumulation of foreign exchange reserves.

Abstract The thesis is from the angle of economic and industrial development, which proves between Taiwan's industrial structure and income distribution are positively correlated. With track of Taiwanese industry change, investigates the change of income distribution economic because of development and industrial structure change. Most of national economic development progress is associated with certain uneven distribution of income. The phenomenon of uneven income distribution is growing, however, is a concern in current worldwide economic development. In this article is the observation of Taiwanese industrial changes from early-day agricultural industry dramatically stepped to industrial industry, then expending toward service industry, to verify which is higher on uneven income distribution among them. This research takes the theories of Fisher and Clark (1939,1940) as foundation, based on productivity and GDP, to build the pragmatic model of Regression Analysis as proof of income distribution affecting to tertiary industrial sectors change in Taiwan. The substantial evidence finds the growth of the service sector increased by 1%, the impact of Taiwan's economic growth is 0.769%, the agricultural sector is 0.103%, while service sector increased by 1%. The worsening of income distribution, caused the agricultural sector decreased by 0.11%. Therefore, we can deduce that the service sector growth more has brought Taiwan's economy growth but also income distribution has significant worse. This study also considers foreign trade is an important economic lifeline of Taiwan, according to the IMF (IMF), Taiwan is the closest relations with the United States in East Asian nations, but China is coming up right after. Thus, this study conducts variables of regression analysis by putting in the United States and China, as proof that China or USA has more impact on our economic growth as policy maker¡¦s reference.

Abstract In the theory of Economics, investment can bring about Multiplier Effect to the whole GNP, no matter in employment, national income, and even economic growth rate, with an uprising influence. Therefore, every country in the world that hopes to develop economy will do all the best it can to attract investment in order to promote economic prosperity. So, establishing an Export Processing Zone (EPZ) is one of the most used ways when the developing countries want to develop economy. Taiwan has set up its EPZs for more than 41 years. The EPZs have played an important role in the national economic development, have laid down an exemplary foundation for Taiwan¡¦s export processing industries, and have written down a footnote of an ideal model in Taiwan¡¦s economic miracle. But due to the changes in economic situations both domestically and internationally, the magnet effect of mainland China¡¦s so-called ¡¨World Factory¡¨ and the establishment of Special Economic Zones in many countries around the world, the investment environments of export processing zones in Taiwan have all suffered a hardship gradually and the competition of attracting investment has become more fiercely from day to day. Luckily enough, the in-zone enterprises have continuously transferred the industrial structure to cope with the industry¡¦s economic changes from the traditional industry¡¦s labor-intensive pattern to the industry cluster in capital, technology and knowledge-intensive patterns. Also, the governments have changed in systems and adjusted the functions constantly so that the enterprises can keep growing and sustain their operations. The paper collected the related plans, documents and secondary data of EPZs¡¦development, regional industrial development, Ping-tung county¡¦s industrial development and the current situations of PEPZ, and then makes the conclusions and analyses, In addition, the paper analyzes the strengths and weaknesses, possible opportunities and threats of inside and outside of the PEPZ by SWOT analysis, and investigated the non-engaged investors by face-to-face interviews about the reasons that they don¡¦t invest in PEPZ for the reference of making the recruiting strategies, and then made questionnaires to the representatives of industries, government officials and scholars in universities by Delphi Method, so as to obtain the primary data and collect and analyze them. The paper quoted some of the researches in regional advantages of industrial models from Professor Wu Chi-hua and Dr. Tsai Jin-kun to analyze the industrial advantages of Ping-tung county, Kaohsiung city and Kaohsiung county, and all of the Export Processing Zones. By making references from Input-Output Tables of the Executive Yuan and the nation¡¦s important industries in the coming ten years, the paper sifted out the industries that PEPZ intends to recruit in the future. And then, through the Delphi Method of expert¡¦s results inspections, the paper made a conclusion that the important industries that PEPZ can recruit includes metal products, energy industry, electronics and its components, automobile and auto-parts, machinery & equipments. In the end, the paper studied the recruiting strategies and practical ways of attracting investment through the theory of SWOT to analyze the recruiting competitiveness of PEPZ. The paper obtained the matrix of SWOT strategic analysis, and drew up SO¡]strength-opportunity¡^strategies, WO(weakness-opportunity) strategies, ST(strength-threat) strategies and WT(weakness-threat) strategies after the expert¡¦s inspections. There are 13 strategies and practical ways .

<p>The aim of this study is to investigate the impact of foreign direct investment (FDI) on economic growth in China during the period 1994-2003. The theoretical framework shows that FDI has a positive impact on economic growth because it serves as a channel through which new technology is transferred from one country to another and thereby it increases output and GDP in the recipient country. Previous researchers’ work on the subject has also been reviewed to be able to interpret the results.</p><p>The research is based on secondary data for 30 different regions in China. The empirical results show a positive but insignificant effect of FDI as a fraction of GDP on the level of GDP when the regression model includes all 30 regions. When the four poorest regions that have almost no inflow FDI are excluded, the regression model continues to show a positive effect of FDI on the level of GDP and in addition, the result is statistically signifi-cant at the 6 % level.</p> / <p>Denna uppsats studerar utländska direkt investeringars påverkan på den ekonomiska till-växten i China under perioden 1994-2003. En teoretisk modell har utvecklats, som visar att utländska direktinvesteringar har en positiv inverkan på ekonomisk tillväxt, då de fungerar som en kanal via vilken ny teknologi överförs till från ett land till ett annat och därmed ökar produktion och BNP i det mottagande landet. Tidigare studier kring ämnet presente-ras också.</p><p>Undersökningen är baserad på sekundär data för 30 olika regioner i Kina. De empiriska re-sultaten tyder på en positiv men icke-signifikant effekt av utländska direktinvesteringar som en del av BNP på BNP-nivån, när regressionsmodellen inkluderar alla 30 regioner. När de fyra fattigaste regionerna med ett näst intill obefintligt tillflöde av utlandsinvesteringar är utelämnade, visar regressionsmodellen ett signifikant resultat på 6 procents signifikantsnivå.</p>

<p>This bachelor thesis in economics examines the Asian financial crisis, the impact on the countries in the region and how well they recovered financially. The countries that are taken into consideration are Japan, Indonesia, South Korea, Philippines, Thailand, Malaysia and Singapore.  The variables used to explain the implications of the crisis are GDP, trade openness, unemployment and current account.</p><p>Descriptive statistics show that the most closed economy that was affected by a current account reversal was also the hardest hit in terms of GDP.  The statistics also show that all the countries under observation have recovered to their situation prior to the crisis in terms of GDP, but not in terms of the level of unemployment.</p><p>Two regressions that were performed showed the relation between trade openness and the effect of GDP after the crisis, and the relation of trade openness to growth after the crisis. The regressions show that the more closed an economy is the larger the effect of a crisis. At the same time these countries had the highest growth rates after the crisis and were also among the first to recover. Theoretical reasons for these results are given.</p>

During the last decade, investments into the Swedish mutual fund market have increased substantially. The increased popularity of actively managed Swedish equity funds among households and investment companies, correspondingly, funds need to deliver substantial results, raised the importance to evaluate these funds’ performance. This thesis adds to the scarce empirical literature on Swedish equity mutual fund performance. Employing the Fama-French three factor model, it analyzes whether actively managed Swedish equity mu- tual funds outperform the Fama-French benchmarks net- and gross of management fees. The study uses time-series data and constructs equally-weighted portfolios of the 42 Swe- dish based actively managed equity mutual funds investing in Sweden for the period 2003- 2013. The portfolios’ excess returns are calculated by estimating the Fama-French three factor model by means of ordinary least squares (OLS) regression analysis. The empirical results show that actively managed equity mutual funds over performed the Fama-French three factor benchmarks by an average annualized net- and gross excess return of 3.60 and 4.67 percent respectively. Sorting out the funds by the performance into deciles, the find- ings indicate that management fees influence the performance of the equity mutual funds in the sample of our study. The conclusion is made such that there is an indication that Swedish equity funds’ managers are able to add value above passive investing.

Anecdotal descriptions and small studies have reported decreasing reimbursements from Medicare Part D sponsors and commercial third-party payers, resulting in decreased gross margins for independent pharmacies; however, reports are inconclusive regarding which payer more greatly affects independent pharmacies’ financial viability. Using 2006-2009 prescription claims data collected by a pharmacy switching company, the purpose of this study was to calculate and describe estimated reimbursement formulas and mean gross margins to assess the relative impact of these two payer groups. The study evaluated a total of 2,929,696 prescription claims paid for by Medicare Part D sponsors (n = 1,830,896) and commercial third-party payers (n = 1,098,800). The prescriptions were dispensed by 418 Texas independent pharmacies to 192,968 patients aged 65 to 94. Between 2008 and 2009, the median ingredient reimbursement ranged from AWP-17% to AWP-15% for Part D sponsors and from AWP-17.44% to AWP-15% for commercial third-party payers. The median dispensing fee ranged from $1.50 to $2.00 for Part D sponsors and from $1.10 to $2.00 for commercial third-party payers. For all payers, the median dispensing fee and median ingredient reimbursement decreased or was stagnant. Similarly, aggregate percent gross margin (calculated using the payers’ estimates of acquisition cost) decreased for both payer types between 2007 and 2009, with the mean gross margin of 4.0 percent earned for Part D prescriptions being higher than the 3.7 percent earned for commercial third-party prescriptions. In the same timeframe, the mean aggregate percent gross margin ranged from 2.8 percent to 6.0 percent among the five most popular Part D sponsors in the sample, and from 2.4 percent to 5.1 percent among the five most popular commercial third-party payers. The generic dispensing ratio explained a portion of the variance between and among payers. This study shows that significant variation exists in reimbursement formulas and percent gross margin between and among several of the most popular Part D sponsors and commercial third-party payers and supports pharmacy assertions that reimbursements from both payer types are decreasing. Pharmacies can respond to these pressures by being more conscientious of their business’ margins when reviewing contracts and increasing the proportion of generic drugs dispensed. / text
