根據Easley, Kiefer, O’Hara and Paperman (1996)所發展的模型，我們可以對台灣證券交易所上市的股票進行訊息交易的研究。我們的結果顯示，交易越活絡的股票含有訊息交易的機率越低；而這與Easley, Kiefer, O’Hara and Paperman的研究結果一致；換句話說，紐約證券交易所與台灣證券交易所的股票對於訊息交易都有類似的特性。因此，根據研究結果，沒有訊息的投資人應該多去交易較活絡或交易量較大的股票，因為這些股票含有訊息交易的機率較低。 / Following the empirical model developed by Easley, Kiefer, O’Hara and Paperman (1996), we have investigated the information content of the stocks on the TSEC. Our result reveals that more liquid stocks have the lower risk of informed trade than do less liquid stocks and this is basically consistent with the finding of Easley, Kiefer, O’Hara and Paperman. Stocks on the NYSE and the TSEC have similar characteristics of informed trade. Therefore, for uninformed traders, it is better for them to trade stocks which are more liquid and have higher trading volume.

This diploma thesis is focused on the analysis of specific type of Value Added Tax fraud called carousel fraud. The main object is to analyse and quantify tax fraud impact specifically oriented to VAT area, i.e. carousel fraud, and suggest the way of prevention which prevent its emergence and expansion in domestic economy. In the theoretical part the information about VAT, the Czech Law on Value Added Tax, EU directive on the common system of Value Added Tax and carousel fraud is described and furthermore, the losses to carousel fraud are mentioned. The practical part is applied to analysis of profit from carousel fraud as a whole and profits of individual participants in carousel fraud, analysis of the Court of Justice of the European Union judgements and the Supreme Administrativ Court of the Czech Republic judgements and carousel fraud prevention in the EU and at home.

Master of Agribusiness / Department of Agricultural Economics / Vincent Amanor-Boadu / Beans and cowpeas are considered nutritionally dense and good sources of protein. In this sense, they are considered excellent food in poor households, especially in those that exhibit high levels of malnutrition or under-nutrition. To address food security and nutrition security in poor countries, there has been an increasing interest in encouraging farmers to grow beans and cowpeas. This has spurred research in value chains for these crops in many countries, especially those that do not traditionally grow them as primary staples. Most of these research efforts have focused on the producer and consumer issues, with little or no attention paid to traders who operated between these two players in the value chain. The objective of this study, therefore, is to contribute to the literature on the bean and cowpea value chain research by identifying the factors influencing the participation decisions of traders in this segment of the agricultural economy in Zambia. Using data collected by the Pulse Value Chain Initiative – Zambia in 2011, a probit model was used to analyze data. The dependent variable trader participation in wholesale marketing of beans and cowpeas in Lusaka and its principal food markets. The explanatory variables encompass trader demographic characteristics and available assets or resources. The research explored the effect of the assets or resources on the choice to trade cowpeas or beans at the wholesale level in Lusaka with and without controlling for traders’ demographic characteristics. Three procurement sources are identified in the study: the local market within which the traders operate; producers/suppliers within Lusaka District; and producers/suppliers outside Lusaka District. The results indicate that the procurement source for beans and cowpeas influenced trader decision to operate at the wholesale level. For example, traders who purchased their produce from locations outside Lusaka District were about 37% more likely to participate in wholesale trade compared to those sourcing their produce within the market in which they operate when demographic characteristics of traders are not controlled for in the model. When the demographic factors are controlled, the likelihood of those procuring from outside Lusaka District participating in the wholesale trade declines slightly to about 34%. These coefficients were both statistically significant at the 1 percent level. The results also showed that traders using credit from friends and family were nearly 18% less likely to participate in wholesale trade than those borrowing from other traders, significant at the 5% level. Controlling for demographic characteristics led to a reduction of this likelihood to about 16.7%, significant only at the 10% level. There were no statistical differences between traders for all education levels and those without any education except for respondents with lower primary and lower secondary education. Traders with lower primary and lower secondary education had a 31% higher likelihood of operating at the wholesale level compared to those without any formal education while those with upper secondary education had about 26.7% higher likelihood of operating at the wholesale level compared to those without any formal education. Marital status was not a discriminant in the decision to operate at the wholesale level. However, males had about a 9% higher probability than females in operating at the wholesale level. Wholesalers tend to move larger volumes of produce and, hence, create wealth much quickly than retailers. Wholesalers are also more likely to be engaging processors when these exist in the supply chain. Given that traders sourcing their produce from outside Lusaka District are more likely to engage in wholesale trading, it recommended that further research into the intricate characteristics of these traders are explored. This future research will do well to explore the factors that specifically differentiate these traders from the others. Understanding these and their potential effects could allow policymakers to provide support and services to this class of traders to engage in structured relationships with larger organizations such as processors and exporters.

Overconfidence and its relationship to investor market participation is well established in the finance literature. The research into investors and social networks is only in its infancy, however. This thesis extends the literature by expanding on both subjects individually, then bringing them together. Empirical work on individual investors in the existing literature links overconfidence and excess trading, resulting in impaired returns. The preferred activity metric, monthly account turnover, encapsulates two separate elements, though. One is trade frequency. The other is leverage use. Chapter 4 of this thesis theorizes based on the existing literature that in fact trade frequency is not a good measure of overconfidence. It then demonstrates through empirical analysis of a group of individual non-professional foreign exchange traders that leverage is much more suitable to that role. Chapter 5 turns the focus to social networks, particularly with respect to information transfer. The literature in finance anticipates that network members benefit from their membership. Further, network position (social capital) enhances that benefit. This thesis challenges that expectation with respect to non-professional investors. Findings based on analysis of members of an online retail foreign exchange trader social network indicate that while there may be an educational benefit accruing to unsophisticated members, for more sophisticated ones membership appears to have a negative effect on returns. One potential explanation for the negative impact of network membership is explored in Chapter 6 in the form of impression management. It is hypothesized that sophisticated investors are influenced in their behaviour by the realization they are being observed, and also the size of their audience. Analysis of foreign exchange traders indicates an increase in leverage use among sophisticated investors as their audience size increases, coinciding with a decline in trade excess returns, making the case for an observation-based rise in overconfidence.

Duty to inform the customer arising from providing investment services is one of the most important institutes of consumer protection in the capital market, especially in light of the recent financial crisis. The aim of this thesis is to comprehensively explain and summarize the issue of disclosure duties of securities trader to the customer. Questions that I ask in this context are: 1) whether the current legislation under the Directive on markets in financial instruments (MiFID I), respectively. Act no. 256/2004 Coll. Capital Market Undertakings Act (Capital Market Undertakings Act) is sufficient; and b) what changes will bring a new directive on markets in financial instruments (MiFID II), respectively amendment to Act no. 256/2004 Coll. Capital Market Undertakings Act (amendment Capital Market Undertakings Act )and whether it is a benefit for the capital market or not. In the introduction I introduce the situation on the capital market in Europe, respectively in the Czech Republic, history and present the information duty when providing investment services and content description of each charter. The first chapter is theoretical and I define in it term of general legal term: information duty, providing investment services, bearer of information duty, and the person entitled to the information....

The topic of this thesis is "Trade license and the requirements for undertaking business as sole trader". Its aim is to analyze the current legal regulations with regard to the historical development and judgments, to evaluate it, to highlight its deficiencies and to deal with possible solutions. I have chosen this particular topic because it's a very relevant topic, one which is constantly developing and as such offers enough food for thought. It also plays an important role in the life of society and in the life of an individual. The thesis is composed of four chapters. Chapter One, subdivided into five parts, summarizes the historical development of the trade law with focus on the main law in this area which was issued in 1859 and became the fundamental document in the subsequent period and influenced current legal regulations too. Chapter Two is divided into four parts. Part One defines the trade license, while Part Two briefly describes its classification. Part Three concentrates on subjects of trade license, including conditions for foreign persons. Finally Part Four deals with the responsible representative. In Chapter Three I focus on the requirements for undertaking business as sole trader. It's consisted of three parts, one about general requirements, one about specific requirements and...

In the first chapter of this dissertation, I examine the relationship between hedging and diversification effects on CEO compensation in the Real Estate Investment Trust (REIT) industry. The REIT industry is suitable for this investigation for various reasons; primarily being that the REIT sample represents a relatively clean sample to study the effects of diversification and hedging on compensations. I find a positive and significant relationship between the interaction variable which reflects the effects of both hedging and diversification and CEO pay-for-performance sensitivity. This is consistent with the notion that managers are in a better position to manage firm risk if they use all the available tools and instruments, including hedging and diversification. I also find a positive and significant relationship between hedging and CEO pay-for-performance sensitivity, indicating that CEO compensation is more short term oriented because hedging is a relatively short term risk reduction strategy. The second chapter of this dissertation examines the relative contribution of regular and e-mini futures market to price discovery of EUR/USD futures contracts on the CME, using intraday data in 2010. The relative contribution to price discovery is estimated using the information share approach proposed by Hasbrouck (1995) and Gonzalo and Granger (1995). Empirical findings indicate that regular futures market accounts for approximately 66.5% of price discovery in the EURO/USD market. This study also examines if the regular future’s information share (IS) can be explained by the positioning of commercial and non-commercial traders. The results support the conclusion that the IS of regular futures can be better explained by non-commercial traders (speculators) than commercial traders (hedgers).

Swiss bank traders are affected by technological and regulatory challenges, which may affect their broker voting process and may result in a change of trading and evaluation behavior in 2018. Compounded challenges exist when broker evaluation strategies are not effective or Markets in Financial Instruments Directive (MiFID) II compliant. This qualitative, single case study, built on efficient capital market hypothesis and innovative disruption theory, was focused on effective broker evaluation strategies after MiFID II in Switzerland. The sample consisted of 4 buy-side traders, who shared their unique perspectives. Methodological triangulation was achieved through semistructured interviews, a review of the institution's publicly available data, and a literature review. The data analysis process consisted of a manual and systematic coding procedure for the sources of inquiry. In the findings, 3 strategies emerged: improvement of the existing organizational structure of the internal voting process, creation of advanced resources and internal technology as well as automation, and improvement of communication internally and externally to expand the trading desk profitability. Participants agreed that, although not regulatory or necessary in Switzerland yet, the broker review process at the organization under study needed to change dramatically to reach European MiFID II compliance. Implications for positive social change include strategies to help traders, trading desk leaders, and bank managers achieve regulatory compliance with MiFID II. The insight gained from this research may help banks and brokers to improve investment responsibility, broaden insight on research, trading, and client service, and promote stronger enforcement of regulations of electronic trading.

In general, an announcement of good news would attract investor to employ margin for a long position, and vice versa. Since only noisy trader can employ credit transaction in Taiwan, this study hypothesizes that investors would follow the announcement for making rational expectation. The results of this study could help understand how noisy traders use a financial forecast. This study selects the samples occurred between 1995 and 1997 to test the established hypotheses. 　　The empirical results can be summarized as follows. 　　●If the announcement of voluntary forecast occurred prior to the release of quarterly, semiannual, and annual reports, both good and bad news simultaneously cause an increase of margin and short transactions during this period. However, the magnitude of margin transactions is significantly higher than that of short transactions. 　　●If the announcement of voluntary forecast occurred subsequent to the release of quarterly, semiannual, and annual reports, both good and bad news simultaneously cause an increase of margin and short transactions during this period; however, the magnitude of margin transaction is significantly higher than that of short transaction. 　　Since noisy traders are essentially information followers, their judgement significantly relates to functional efficiency of informational intermediaries. These empirical results imply the function of informational intermediaries requires further improvement.
