The Administration Yuan Department of Health revised the medical treatment method, the third reading to have already passed on April 28th in 93 years. Revise the point be increasing the medical juristical person particularly the chapter the part already the clear statement standard it to change the system and build up the system. This research is standard according to the latest medical treatment organization classification that announced, the current conditions that inquires into the medical treatment organization finance information to make public currently, and from the point of view of stackholders:Investors and donators, analyzing the reading of hospital¡¦s public information for different relation persons, the usage index sign of the financial report, relatively manage it with company mutually the congeniality, the aptness and urgency that makes public currently for the hospital finance information is the research point of this thesises. Hospital's user in the information is divided into the exterior inspector,investor and inner part the governor, the hospital and company are establishing the dissimilarity on the property, the index sign that make public is also different, ducting in to make public the feasibility of the information with the analytical hospital from here. The medical treatment juristical person for match with the ordinance provision and reach the society direct to carry out the information to make public, is an irresistible general trend. With Department of Health announce the corporate body hospital financial report and each hospital manages the data the finance that make public voluntarily on the website for sample carry on the discussion. Because the medical treatment juristical person organization belongs to the not-for-profit organization, making public in the finance information up is different from in appear on market the listed company generally, The purpose of this research is inquiring into the hospital in order to respond the all society to inspect the public wealth to fly to, it carries on the public finance clarity and importance's lying in through the public lesson responsibility to safeguard the public benefit and the others rights, by the publication and transparency of the finance information, the public-spirited service and the mission responsibility that let the people understand and recognizes the pure hospital to should have, makes public the index sign and the rating result to information, expect the idea that can build up inspecting the hospital information to make public, being the investor and donator contributing money the reference that the person carries on making policy. This research makes use of the domestic and international cultural heritage research through ising analytical than the research, letting the donator known the management information and funds that its organization should make public the hospital to fly to, making the hospital be able to participate the social salvage more physically, Letting the investor known to take hospital as to invest the object of information's making public should belong to which contents, making the funds of the capital market flowed into the medical treatment industry, reaching the correction lawmaking purpose of the medical treatment method. Carrying out the hospital manages the mechanism to mainly expect to lie in the trust that can raise to contribute money the person and investor to the medical treatment juristical person, Making the national health insurance resource ability reasonable assigned through the publicly transparent finance information, reducing the medical treatment juristical person organization and an output information dissymmetry of the National Health Insurance Bureau and the morals risk of the occurrence, Passing by the public finance information makes public, and combines the exterior resultant force direct, can make to contribute money the person,investor eventually, the public ,the medical treatment promoter and the health insurance bureau to all win.

This paper studies the effect of information disclosure on banks' portfolio risk. We cast a simple banking system into a general equilibrium model with trading frictions. We find that the information disclosure lowers the expected risk-adjusted profits for a non-negligible fraction of banks. The magnitude of this effect depends on the structure of the banking system and, alarmingly, it is more pronounced for systemically important institutions. We connect these theoretical findings to the stress test procedure, where bank information is disclosed by the regulator. The 2011 and 2014 stress tests are used in an empirical study to further support our theoretical results.

Abstract This thesis is examining not only the relationship between earnings management and information disclosure but also which information disclosure dimensions influence earnings management in banks and financial holding corporations. I classified the information into five dimensions and they are independent variables in this thesis. Due to different industrial characteristics among financial and other industries, I didn¡¦t use The Healy Model ( 1985), The Jones Model (1991), The DeAngelo Model(1986), The Modified Jones (1995) Model to estimate earnings management. Instead, I choose eight proxies selected in Liu¡¦s paper (1999), and they are Bad Debt, Provisions of Other Loss, Gain on Disposal of Investment, Loss on Disposal of Investment, Gain -Disposal of Fixed Asset, Loss -Disposal of Fixed Asset, Gain on Trading S-T Investment, Loss on Trading S-T Investment as the earnings management proxies for financial industry. Hence, I also chose those proxies as my earnings management proxies. The results show that the total scores of information disclosure are not related to earnings management in banks and financial holding corporations. On the other hands, it is the score of information disclosure dimensions related to earnings management. It demonstrates that different information disclosure dimensions influence the earnings management in different ways for banks and financial holding corporations. Key words: earnings management, information disclosure, banks, financial holding industry

Background: In the last decades voluntary disclosure has become more common. The available research on the subject has mainly focused on the motive of voluntary disclosure rather than the content or what kind of information is published most frequent. There is a shortcoming in the academic literature about what information outflow is focused on and to whom. Henceforth this study aims to analyze the voluntary disclosure in the annual report among listed companies on the Swedish Stock Exchange. Purpose: The purpose of the study is to operationalize and describe voluntary disclosure to contribute empirically to the knowledge gap within the subject. The study intends to clarify the type of voluntary disclosure that dominates in annual reports on Stockholm Stock Exchange. Method: To answer our purpose of this study as well as possible we conducted a qualitative content analysis with selected companies’ annual reports. This literature study has an abductive research strategy based on collecting empirical data from the annual reports of the companies with the most new owners by 2020. Based on a checklist and a coding scheme, the empirical data will be quantified, analyzed and compared. Results and conclusions:We found in accordance that the companies published a considerably high amount of voluntary disclosure in their annual report. The companies with the most new owners distinguished themselves by publishing more voluntary information than companies with fewer new owners. The categories of voluntary disclosure that were given the highest priority were financial information about the company and organization.

Background and problem – As a result of financial crises and the realization of a broader stakeholder network, recent decades have seen an increase in stakeholder demand for non- financial information in corporate reporting. This has led to a situation of information overload where separate financial and sustainability reports have developed in length and complexity interdependent of each other. Integrated reporting has been presented as a solution to this problematic situation. The question is whether the corporate world believe this to be the solution and if the development of corporate reporting is heading in this direction. Purpose - This thesis aims to examine and assess to what extent companies listed on the OMX Stockholm 30 (OMXS30), as per 2016-02-28, comply with the Strategic content element of the <IR> Framework and how this disclosure has developed since the framework’s pilot project and official release by using a self-constructed disclosure index based on its specific items. Methodology – The purpose was fulfilled through an analysis of 104 annual reports comprising 26 companies during the period of 2011-2014. The annual reports were assessed using a self-constructed disclosure index based on the <IR> Framework content element Strategy and Resource Allocation, where one point was given for each disclosed item. Analysis and conclusions – The study found that the OMXS30-listed companies to a large extent complies with the strategic content element of the <IR> Framework and that this compliance has seen a steady growth throughout the researched time span. There is still room for improvement however with a total average framework compliance of 84% for 2014. Although many items are being reported on, there are indications that companies generally miss out on the core values of Integrated reporting.

為提升資訊透明度，國內於2003年開始實施資訊揭露評鑑系統，由過去實證結果發現，系統實施後有助於降低企業盈餘管理行為。第三屆起，評鑑結果分五級揭示並新增自願性揭露較透明名單，期以再強化資訊透明度。因此，本研究乃針對第三屆系統改變及其結果，進一步探討對於企業盈餘管理行為的影響。 　　本研究實證結果發現，第三屆資訊揭露評鑑系統改採分五級揭示評鑑結果，比前兩屆僅揭示較透明者更能降低企業盈餘管理行為。另外，在系統實施後，公司規模較大者，其盈餘管理行為降幅較小公司為多。而在評鑑結果對於盈餘管理行為之鑑別上，以級別來說，前兩級(A+、A級)明顯小於後兩級(B、C級)，但後兩級之間則無差異；以自願性揭露較透明與否來說，較透明者其盈餘管理小於較不透明者。 / In order to improve the transparency of information, Taiwan Securities and Futures Institute (SFI) begins to implement Information Disclosure and Transparency Ranking System (IDTRS) in Taiwan in 2003, since that the past study shows applying IDTRS can reduce earnings management behaviors of the enterprise. In the third time of practice, the result of IDTRS was divided into five grades and released a more transparent list on companies in order to strengthen the transparency of information better. Therefore, this study focuses on the result of IDTRS released in 2006 and discusses the effect of the result to earnings management behaviors. The empirical result of this study shows that the change does reduce earnings management. Besides, this study also shows that, after the change, the earnings management behavior of the large company decreases more than that of the small company. Finally, to determine whether the result of IDTRS can differentiate earnings management behavior of each company, the study shows, from the perspective of the grade, the first two grades (A+, A) are obviously smaller than last two grades (B, C), and it has no difference between the last two grades; from the perspective of voluntary disclosure of transparency, the earnings management of the more transparent company is lower than the that of the less transparent company.

Nowadays, people have many business activities and entertainments on a variety of online platforms. Despite their various functionalities, online platforms have a fundamental administrative problem: How do platform designers or administrators create proper online environments, including mechanisms and policies, to better manage user behaviors, in order to reach the goals of the platforms? Starting with a taxonomy of online platforms, I introduce three critical dimensions that help to characterize such platforms, including revenue model, heterogeneity in the role of users and level of user interaction. Then, I choose three online platforms as research contexts and conduct empirical studies, trying to identify and understand the impact of the incentive program, quality information disclosure, and social influence, on users' decision-making in online platforms. The first essay investigates the effectiveness of incentive hierarchies, where users achieve increasingly higher status in the community after achieving increasingly more challenging goals, in motivating user contribution in the same platform. The findings have important implications for crowd-based online applications, such as knowledge exchange and crowdsourcing. The second essay focuses on online consumer review sites, and studies whether and how consumer-generated word-of-mouth of restaurants-both volume and valence-is influenced by the disclosure of quality information from health inspectors, by conducting analytical modeling and econometric analyses using data from a leading consumer review site. The third essay examines how social interactions matter in a large-scale online social game that adopts an increasingly popular freemium revenue model. The study leverages an econometric model to quantify the effect of peer consumption on players' repeated decisions for the consumption of both free services and premium services. Finally, I conclude the dissertation by highlighting the three fundamental issues of design and management of online platforms.

The existing literature on information disclosure commonly assumes full commitment to truthful disclosure and therefore revelations are always credible, which can be quite unrealistic in many circumstances. This thesis mainly contributes to the literature by studying information disclosure in the form of cheap-talk in auctions and monopoly pricing, which allows for mis-reporting and false disclosure. The thesis is composed mainly of three research papers. The first paper (Chapter 2), also the major chapter of this thesis, investigates cheap-talk information disclosure in auctions, where bidders' preferences are horizontally differentiated. The seller may reveal information of product attributes before the auction, and the disclosure policy is characterized by a partition of the attribute space. In a symmetric setting, I first show that informative equilibria reveal the feature that more precise information is provided for less popular product attributes. Second, I prove an equilibrium existence theorem that an informative equilibrium can be supported by an information partition of any degree, as long as the number of bidders is sufficiently large. And finally, the optimal disclosure policy reveals a complementarity relationship between the number of bidders and the optimal degree of equilibrium partitions. In this chapter, optimal information structure is endogenously determined. In the second paper (Chapter 3), I turn to study how a monopoly seller should reveal a product's horizontal attributes, when consumer preferences conform to a mixture distribution. I show that the optimal disclosure policy largely depends on the characteristics of the mixture distribution. Specifically, when consumer preferences are highly heterogenous, it is better for the seller to reveal information and serve different groups of consumers separately. And when the preference distribution becomes more asymmetric, cheap-talk disclosure is more likely to be dominated by no disclosure at all. In this chapter, information structure is taken as given. The third paper (Chapter 4) studies optimal regulation of risk-averse producers, in a setting of complementary production with independent cost realization. The production can be organized in the form of either component, or integrated production. I show in this paper that the relative virtues of these two forms of production depend on the degree of risk aversion of the producers.
