IntroductionThe U.S. syndicated loan market bridges the private and public debt markets and provides borrowers and lenders with a highly valuable source of financing and investment. The market consists of a wide-range primary loan market, where syndicated loans1 are originated, and an active secondary market, where loans are traded after the close of primary syndication. In the past 20 years, the syndicated loan market has been one of the most rapidly growing and innovative sectors of the U.S. capital market (Yago and McCarty, 2004). U.S. firms obtain over $1 trillion in new syndicated loans each year, which represents more than 50 percent of the annual U.S. equity and debt issuance (Weidner, 2000). The trading of syndicated loans has expanded from $8 billion in 1991 to $144.6 billion in 2003, a compound annual growth rate of 27 percent.In this paper, I employ a sample of traded syndicated loans to explore two fundamental concepts in accounting and finance research: information asymmetry and financial reporting quality. The existing literature that examines information asymmetry does so mainly in a context of equity markets,2 leaving the role of information asymmetry in the debt markets largely unexplored. The secondary loan market is a promising empirical setting to examine information asymmetry because it involves trading of debt securities of both public and private firms. Moreover, the secondary loan market provides unique information regarding trading of private debt issues.The first contribution of this paper is to explore how information asymmetry, as reflected in firm- and loan-specific characteristics, affects secondary loan trading spreads. Prior research primarily addresses loan sales by investigating banks’ incentives for loan trading3 and by1 In the syndicated loan market a loan is identified as a “facility”. Usually, a number of facilities with different maturities, interest rate spreads and repayment schedules are structured and syndicated as one transaction (deal) with a borrower. The analysis in this paper is performed at the individual facility level.2 See, for example, Copeland and Galai (1983), Glosten and Milgrom (1985), Kyle (1985), Amihud and Mendelson (1986), Diamond and Verrecchia (1991), Botosan (1997), Leuz and Verrecchia (2000), Easley et al. (2002), Easley and O’Hara (2004), Ertimur (2004) and Schrand and Verrecchia (2005).3 See Pavel and Phillis (1987), Pennacchi (1988), Gorton and Pennacchi (1995), Froot and Stein (1998), Demsetz (2000) and Cebenoyan and Strahan (2004).examining returns and price formation across the loan, bond and equity markets4. To the best of my knowledge, this study is the first to examine the determinants of the bid-ask spread in the secondary loan market.The empirical findings confirm that the bid-ask spread in the secondary loan trade is positively related to firm- and loan-specific characteristics associated with a high information asymmetry environment. There is clear evidence that loans of private firms are traded at higher spreads than loans of publicly reporting firms. The bid-ask spread is also significantly higher on loans without an available credit rating. Emphasizing the dominant role of the arranger of syndication in resolving information asymmetry, the results indicate that loan spreads are higher for loans syndicated by less reputable arrangers. I also find that loans of loss firms are traded at significantly higher spreads than facilities of profitable ones. Furthermore, the stronger adverse selection associated with distressed loans is reflected in the higher trading spreads of these loans.The analysis presented in this paper enriches our understanding of how information asymmetry is resolved in trading of private debt securities. I identify the determinants of the efficiency of the secondary loan trade5 and quantify their impact on the trading spreads. While a number of these determinants are documented by prior research to be associated with information asymmetry, others address the specificity of trading on the secondary loan market. The empirical analysis employs unique characteristics of the information environment of syndicated loans, such as the reputation of the arranger of syndication, the identity of the lender (i.e., institutional investor or bank), the loan-specific ratings, and the distinction between both distressed6 and par loans and profit and loss borrowing firms. The analysis of the firm- and loan-specific characteristics associated with a high information asymmetry environment not only widens our4 See Allen et al. (2004), Altman et al. (2004), and Allen and Gottesman (2005).5 Copeland and Galai (1983), Glosten and Milgrom (1985) and Kyle (1985) confirm that information asymmetry between potential buyers and sellers introduces adverse selection and reduces the liquidity in the secondary markets. Following this line of research, by “more efficient secondary trading” I imply more liquid trading, which is reflected in relatively lower bid-ask spreads.6 According to the secondary loan market’s convention, distressed loans are loans traded at a bid price below 90 percent of the par value.understanding of the role of information asymmetry in loan trading, but it is also a necessary step for exploring the impact of financial reporting quality on trading of private debt securities.The second contribution of this paper is to examine how financial reporting quality affects loan trading on the secondary market. Studies of financial reporting quality have mainly focused on equity markets,7 although Watts and Zimmerman (1986), Watts (1993, 2003a,b) and Holthausen and Watts (2001) conclude that the reporting demands of the debt markets principally influence accounting reporting. Therefore, the secondary loan market is both a natural and an important empirical setting in which to examine the role of financial reporting quality. More specifically, I investigate how the quality of financial reporting affects loan trading spreads, with a particular emphasis on exploring the impact of timely loss recognition.Since debt holders’ returns are mainly determined by the downside region of a borrower’s earnings distribution, investors in debt securities are more sensitive to borrowers’ losses than to borrowers’ profits. In addition, timely loss recognition more quickly triggers ex-post violations of debt covenants based on financial statement variables. By triggering debt covenant violations, timely loss recognition allows lenders to more rapidly employ their decision rights following economic losses, which increases the efficiency of debt agreements (Ball, 2001, Watts, 2003a, and Ball and Shivakumar, 2005a). The asymmetric payoff function of investors in debt securities and the effect of timely loss recognition on the debt contracting efficiency make the secondary loan market an excellent empirical setting in which to explore the importance of timely loss recognition.The impact of timely loss recognition on debt agreements should be particularly important for private debt contracts because private debt issues typically contain more extensive covenants than do public debt issues (Smith and Warner, 1979). Previous literature also demonstrates that private lenders set debt covenants fairly tightly relative to the underlying financial variables,7 The exceptions include Sengupta (1998), Ahmed et al. (2002), Beatty et al. (2002), Bharath, Sunder and Sunder (2004), Zhang (2004) and Francis et al. (2005).especially when compared to the covenants set by public lenders (DeAngelo et al., 1994, Assender, 2000, Dichev et al., 2002, and Dichev and Skinner, 2002).These differences between private and public debt contracts make the secondary loan market an especially promising setting for an empirical analysis of how timely loss recognition affects debt agreements.I employ three measures of timely loss recognition. First, following Ball and Shivakumar (2005a,b), timely loss recognition is estimated by the coefficient on a firm’s negative cash flows in a piecewise-linear regression of accruals on cash flows.8 Second, following Basu (1997), the timeliness of income in reflecting economic losses is measured by the coefficient on the current year negative stock returns in a piecewise-linear regression of earnings on the contemporaneous stock returns. Estimating Basu’s (1997) model by industry-specific and firm-specific regressions provides two additional measures of timely loss recognition.I find evidence that timely incorporation of economic losses in borrowers’ financial statements reduces the bid-ask spread at which their loans are traded. The effect of timely loss recognition on the trading spreads is statistically and economically significant; the evidence is consistent across different measures of timely loss recognition. These empirical findings confirm that high quality financial reporting reduces the information costs associated with debt agreements and thus increases the efficiency of the secondary loan trade. To the best of my knowledge, this paper is the first to document and quantify the efficiency gain from timely loss recognition in trading of securities on secondary markets.Although accounting theory suggests that timely incorporation of economic losses enhances the efficiency of debt contracting, there is little empirical evidence supporting this proposition.9 By providing evidence that timely loss recognition decreases information asymmetry regarding the borrower, my paper confirms that conservative reporting creates efficiency gains in debt contracting.8 Because of data limitations, this estimation is performed at the industry level.9 The exceptions include Ahmed et al. (2002) and Zhang (2004), who document that timely incorporation of economic losses reduces the cost of debt capital.To further examine the impact of financial reporting quality on loan trading, I investigate the relation between the bid-ask spread and timely gain recognition, the overall timeliness of a borrower’s financial reporting, as measured by R2 of the Basu regression, and unconditional conservatism. The results demonstrate that these attributes of accounting reporting are not significantly related to the loan trading spread. These findings further support the special role timely loss recognition plays in debt contracting.I also examine whether abnormal accruals influence loan trading spreads.10 While I do not observe a significant relation between unsigned abnormal accruals and the bid-ask spread, I find a positive and significant relation between signed abnormal accruals and the loan spread. I interpret these results as evidence that managers choose income-increasing accounting procedures to avoid or to mitigate debt covenant violations. Secondary market participants perceive loans with binding covenants as being subject to higher information uncertainty and this is reflected in the higher spreads of these facilities. The high information asymmetry environment associated with loans subject to binding covenants might be driven by managers’ manipulative behavior, as well as by the general uncertainty regarding the borrower’s creditworthiness and liquidity.My interpretation of the positive relation between the loan bid-ask spread and the signed abnormal accruals is consistent with the “debt covenant” hypothesis that suggests that managers make accounting choices which decrease the likelihood of debt covenant violations (Watts and Zimmerman, 1986, Healy and Palepu, 1990, DeFond and Jiambalvo, 1994, Sweeney, 1994, and Dichev and Skinner, 2002). To strengthen the empirical findings, I conduct a detailed examination of the loan contracts of the loans in the highest decile of signed abnormal accruals. Consistent with the “debt covenant” hypothesis, I find that the majority of firms with high positive abnormal accruals either violate debt covenants or have corresponding financial measures which are only two to four percent higher than the covenant threshold.10 Abnormal accruals are estimated by the Jones (1991) model, adjusted for the incorporation of the negative cash flow indicator variable. This adjustment reflects the role of accruals in timely recognition of economic losses, as suggested by Ball and Shivakumar (2005b).I also examine earnings volatility which the literature sees as being associated with a firm’s information environment. I find a positive relation between bid-ask spread and earnings volatility.11 The significance of this relation is, however, sensitive to the earnings category employed in the analysis. This sensitivity is potentially explained by the equivocal relation between earnings volatility and the quality of financial reporting. Highly predictable and smooth earnings decrease uncertainty about the borrower. However, if managers report opportunistically to achieve lower earnings variability, earnings are less informative (Francis et al., 2004).The following section provides a brief description of the secondary loan market. The third section outlines the research hypotheses. The fourth section describes the data and summary statistics. The fifth section focuses on the research design. The sixth section discusses empirical findings. The seventh section concludes.2. The secondary loan market: Background and developmentSecondary loan sales occur after the close of primary syndication; loan sales are structured as either assignments or participations.12 When interests in the loan are transferred by assignment, the buyer becomes a direct signatory to the loan. In participation, the original lender remains the holder of the loan and the buyer takes a participating interest in the existing lender’s commitment (Standard &Poor’s, 2003). While assignments usually require the consent of both the borrower and the arranger for the loan sale, in participations such consents are almost never required. Today, loan sales are performed through loan trading desks in more than 30 institutions which act as the market makers in the secondary loan market (Taylor and Yang, 2004).The secondary loan market has grown rapidly in recent years, with trading volume increasing from $8 billion in 1991 to $144.6 billion in 2003 (Loan Pricing Corporation (LPC), 2003). The market expanded in both par and distressed loans; the trading volume of loans traded11 Earnings volatility is estimated relative to a firm’s volatility of cash flows (Leuz et al., 2003).12 The majority of the loan sales in the secondary loan market are performed via assignment.at par and of distressed loans reached $87 billion and $57 billion in 2003, respectively. Leveraged loans represent the largest and the fastest growing part of the secondary loan market.13 Since 2001, trading of leveraged loans has constituted 80 percent of the total value of par loan trades.The involvement of institutional investors in the secondary loan market has increased considerably with the market’s development. Banks, loan participation mutual funds (prime funds)14, Collateralized Loan Obligations (CLOs)15 and finance companies constitute the main secondary loan market participants. Additionally, hedge funds and pension funds are increasing their activity in loan trading (Yago and McCarty, 2004).Several reasons contributed to the strong growth in loan sales. New bank regulatory requirements, such as the 1989 Highly Leveraged Transaction guidelines and the 1988 Basel Capital Accord, encourage banks to decrease their credit risk exposure (Altman et al., 2004, and Barth et al, 2004). Additionally, the adoption of SEC Rule 144A in 1990 provided a safe-harbor relief from the registration requirements of Section 5 of the Securities Act of 1933 for the resale of privately held debt and equity securities to qualified institutional buyers (QIB) (Allen et al., 2004, Hugh and Wang, 2004, and Yago and McCarty, 2004).16 The foundation of the Loan Syndication and Trading Association (LSTA)17 in 1995 was an additional factor that stimulated the development of the secondary loan market (Hugh and Wang, 2004).Development of the secondary loan market coincided with improvements in the market’s transparency. In 1987, LPC initiated the publication of Gold Sheets which provide a detailed 13 LPC defines leveraged loans as loans rated below BBB- or Baa3 or unrated and priced at the spread equal or higher than 150 bps above Libor.14 Prime funds are mutual funds that invest in leveraged loans. For the most part, prime funds are continuously offered funds with quarterly tender periods or true closed-end, exchange-traded funds (Standard &Poor’s, 2003).15 The CLOs purchase assets subject to credit risk (such as syndicated loans and mainly leveraged syndicated loans), and securitize them as bonds of various degrees of creditworthiness.16 QIB is defined as an institution that owns and manages $100 million ($10 million in the case of a registered broker-dealer) or more in qualifying securities. For a banking institution to qualify as a QIB, a $25 million minimum net worth test must also be satisfied. The objective of Rule 144A is to increase the efficiency and liquidity of the U.S. market for equity and debt securities issued in private placements by allowing large institutional investors to trade restricted securities more freely with each other.17 LSTA is a not-for-profit organization dedicated to promoting the orderly development of a fair, efficient, liquid and professional trading market for corporate loans and other similar private debt ().analysis of the market trends, loan price indexes and news coverage. In the late nineties, LSTA created standard documentation for primary and secondary loan markets and, jointly with LPC, started providing mark-to-market loan pricing based upon dealer quotes (Yago and McCarty, 2004). These initiatives significantly increased the amount of information available to secondary loan market participants. In addition, Standard & Poor’s, Moody’s and Fitch-ICBA started rating corporate syndicated loans in 1995. The rapid increase in the number of rated loans considerably reduced information uncertainty in the secondary loan market.3. Research hypotheses3.1 Impact of information asymmetry on secondary loan tradingCopeland and Galai (1983), Glosten and Milgrom (1985) and Kyle (1985) confirm that information asymmetry between potential buyers and sellers introduces adverse selection into secondary markets and reduces market liquidity. Following these theoretical models, many papers rely on the bid-ask spread as the main measure of information asymmetry.18 Because private debt contracts are subject to high information asymmetry, I expect information asymmetry, as reflected in firm- and loan-specific characteristics, to significantly influence loan trading spreads.The majority of loan trading involves leveraged loans; borrowers with this credit rating spectrum are expected to rely mainly on bank monitoring (Diamond, 1991). Diamond (1984) establishes that banks provide unique services in the form of credit evaluation and the monitoring of borrowers.19 For a bank to have the incentive to provide these services, it seems necessary that it hold a significant fraction of each loan that it originates. Although prior research addresses a bank’s motivation to monitor a loan after a portion of the loan has been sold, the efficiency of the18 See, for example, Lee et al. (1993), Yohn (1998), Leuz and Verrecchia (2000), Kalimipalli and Warga (2002), Ertimur (2004) and Sadka and Sadka (2004).19 Lummer and McConnell (1989) further support the importance of bank monitoring. Their study suggests that a bank is not producing information upon first contact with a borrower; rather, it learns information or takes action later in a course of a loan.post-sale bank monitoring remains an open theoretical and empirical question (Pennacchi, 1988, Gorton and Pennacchi, 1995, and Gorton and Winton, 2000). Since the relative advantage of bank monitoring is significantly higher for loans subject to high information asymmetry, I expect these facilities to be traded at higher information costs on the secondary loan market.By monitoring a borrower, lenders typically get access to a firm’s private sources of information which indicate its creditworthiness. However, the trading of syndicated loans involves secondary loan market participants who do not possess information sources available to lenders holding a loan contract. Therefore, information asymmetry should considerably affect the bid-ask spreads in the loan trading.20 Additionally, most secondary loan market participants are large institutions, such as banks and institutional investors, and Diamond and Verrecchia (1991) demonstrate that large traders are especially concerned about liquidity.The significant impact of information asymmetry on secondary market trading and its particular importance in private debt contracting lead to the following research hypothesis: H1: The bid-ask spread in secondary loan trading is positively related to firm- and loan-specific characteristics associated with a high information asymmetry environment.First, I focus on variables which previous research suggests as being related to information asymmetry. Second, to address the specificity of trading on the secondary loan market, I explore the unique characteristics of the information environment of the syndicated loans.Publicly reporting vs. private firmsWhen a borrower does not report to the SEC, secondary market participants have less publicly available information regarding a borrower’s creditworthiness and profitability. In addition, private firms are not subject to the rigorous monitoring by market forces, such as the SEC, auditors, analysts and public exchanges. Private firms are also less subject to litigations20 This prediction is strengthened by Gorton and Pennacchi (1990), who show that trading losses associated with information asymmetries can be mitigated by designing securities which split the cash flows of underlying assets into safer and riskier cash flows. Their analysis implies that loans of borrowers with more transparent information should be more efficiently traded by the “uninformed investors”.related to financial reporting and disclosure. Therefore, investing in debt securities of private firms usually requires that the lender have a higher screening and monitoring ability.Diamond and Verrecchia (1991), Leuz and Verrecchia (2000) and Verrecchia (2001) establish that a commitment to higher disclosure quality reduces information asymmetry. Since public firms have an inherent commitment to higher disclosure levels compared to private firms, this information underscores how important public reporting is to the reduction of information asymmetry regarding the borrower. In addition, private firms have less conservative reporting than public firms (Ball and Shivakumar, 2005a), which further emphasizes important differences in their information environments. I expect public borrowers’ debt securities to be traded with less information costs on the secondary loan market. Firms with public reporting are identified by an indicator variable taking the value of one if a borrower is a publicly reporting firm in the year when the facility is traded on the secondary loan market, zero otherwise.Availability of public credit ratingIf an independent credit agency does an evaluation of the borrower’s credit quality, then the availability of this estimate is anticipated to be associated with a lower information asymmetry environment (Dennis and Mullineaux, 2000, Lee and Mullineaux, 2004, and Gonas et al., 2004). The significance of the availability of a credit rating is also supported by the theoretical model of Diamond (1991) which emphasizes the importance of publicly available information, such as credit ratings, to the lender-borrower relationship. The existence of a credit rating is measured by an indicator variable taking the value of one if a firm and/or facility has an available credit rating, zero otherwise. More specifically, I carefully account for all potentially available credit rating categories, including Moody’s Sr. Debt, Moody’s Loan Rating, S&P Sr. Debt, S&P Loan Rating, Fitch LT and Fitch Loan Rating.Loan sizeFollowing previous literature, I use loan size as an additional measure associated with the amount and quality of information available regarding a borrower. According to Jones et al.(2005), information asymmetries tend to be less severe for large loans, since any fixed costs associated with obtaining information about a borrower are less of an obstacle for large loans. Bharath, Dahiya, Saunders, and Srinivasan (2004) also suggest that small borrowers have greater information asymmetries, and a loan’s size is typically positively correlated with its borrower’s size. Additionally, Diamond and Verrecchia (1991) demonstrate that large firms receive a larger benefit from disclosure than small firms. Generally, firm size is a widely used proxy for the amount of public information available regarding a company (Harris, 1994). As a result, larger loans are anticipated to be associated with lower information asymmetry environment.Reputation of the arranger of syndicationTo address the arranger’s dominant role in resolving information asymmetry in the syndicated loan market, the analysis incorporates the reputation of the syndicated facility’s arranger. The arranger negotiates the loan agreement, coordinates the documentation process and the loan closing, recruits loan participants and arranges the administration of repayments (Dennis and Mullineaux, 2000, Panyagometh and Roberts, 2002, and Lee and Mullineaux, 2004). While there is technically an independent loan agreement between the borrower and each of the investors, in practice, the syndicate participants typically rely on the information provided by the arranging bank (Jones et al., 2005).21 Therefore, the arranger’s reputation is expected to be negatively associated with information costs in the secondary loan trade.The importance of the arranger’s reputation is further motivated by the empirical evidence that more reputable arrangers are more likely to syndicate loans and are able to sell off a larger portion of a loan to the syndicate participants (Dennis and Mullineaux, 2000, Panyagometh and Roberts, 2002, and Casolaro et al., 2004). The literature interprets these findings as consistent with the proposition that the arranger’s status is a certification of the borrower’s financial 21 Prior literature suggests that the arranger does not exploit asymmetric information to distribute lower-quality loans to syndicate participants. A number of studies find that the arranger holds larger proportions of information-problematic and riskier loans in its own portfolio (Simons, 1993, Dennis and Mullineaux, 2000, Lee and Mullineaux, 2004, Jones et al., 2005, and Sufi, 2005). In addition, the arranger has been found to syndicate a larger proportion of a loan subsequently upgraded (Panyagometh and Roberts, 2002).。

这种不平等可能会导致市场出现失败，影响资源的有效配置，甚至扭曲整个经济的运行。
信息不对称问题在各种市场中都普遍存在。
例如，在二手车市场上，卖方可能对车辆的质量和历史了解得比买方更多，这就会导致潜在的欺诈行为。
在医疗市场上，医生对疾病诊断和治疗方案的知识远远超过患者，这就可能导致医患双方的信息不对称。
在金融市场上，资金提供方可能对借款人的风险了解更多，这就可能导致贷款利率的扭曲和不公平。
信息不对称问题不仅对个体决策产生影响，也会对整个市场的效率和公平性造成影响。
为了解决信息不对称问题，经济学家提出了一系列的解决方案。
例如，通过加强监管和信息披露，可以减少信息不对称带来的不确定性；通过建立声誉机制和信用体系，可以降低信息不对称带来的道德风险；通过引入第三方中介机构，可以缓解信息不对称带来的交易风险。
在当代经济中，信息不对称问题依然是一个需要重视的挑战。
随着科技的发展，信息不对称问题可能会呈现新的表现形式，因此我们需要不断寻求创新的解决方案，以确保市场的公平和高效。
另外，信息技术的发展也为解决信息不对称问题提供了新的可能。
互联网的普及使得信息更加容易获取和传播，这有助于提高市场的透明度，减少信息不对称。
比如，在电子商务领域，消费者可以通过在线评价和比较平台获取产品信息，这有助于消除卖方和买方之间的信息不对称，提高交易的效率。
此外，教育和培训也可以帮助人们更好地理解和利用信息，在一定程度上减轻信息不对称带来的影响。
通过提高整个社会的信息素养水平，可以减少信息不对称带来的负面影响，促进更公平的市场交易。
在政府层面，加强监管和法律制度建设也是解决信息不对称问题的重要手段。
通过制定相关法规和政策，保护消费者权益、加强市场监管、促进信息披露，可以有效降低信息不对称带来的交易风险，维护市场秩序。
行政决策中的信息不对称问题分析
行政决策中的信息不对称问题分析信息不对称是指在信息交流过程中，一方拥有比另一方更完整或更准确的信息，导致决策过程中的不公平或不理想结果。
在行政决策中，信息不对称问题经常出现，给决策的科学性、公正性和效率性带来挑战。
本文将对行政决策中的信息不对称问题进行分析，并提出应对措施。
信息不对称可能导致决策过程中的不公平。
政府部门在决策过程中通常拥有更多的信息资源，而社会公众往往信息受限。
这种信息不对称可能导致政府对决策后果的影响力过大，而公众无法对决策结果进行有效的监督和评价。
这样的信息不对称问题容易导致行政决策的不公正性，甚至会滋生腐败行为。
信息不对称可能导致决策结果的不理想。
在行政决策中，信息的不完整性和不准确性可能导致决策者基于错误信息做出不恰当的决策。
特别是在复杂的政策环境下，决策者往往需要依赖专业知识和科学研究来做出决策。
如果有关专业知识的信息不对称问题存在，决策结果可能不仅无法达到预期目标，还可能产生负面影响。
针对行政决策中的信息不对称问题，有以下几点建议。
加强信息公开和透明度。
政府部门在决策过程中应主动公开决策依据、数据和分析报告，提供决策过程的参与机会，增强公众对决策的理解和监督。
同时，政府可以利用信息技术手段，建立信息交流平台，提供便捷的信息服务，让公众更容易获取相关信息。
加强决策者的专业能力和知识储备。
政府部门应加强对决策者的培训和教育，提高其专业能力和决策水平。
政府部门还可以通过与专业机构和研究机构的合作，获取最新的科学研究成果和专业意见，为决策提供准确的信息支持。
建立有效的反馈机制也是解决信息不对称问题的关键。
政府部门应主动征求公众的意见和建议，并及时回应公众的关切和疑虑。
政府还可以利用评估和监测机制，对决策的实施效果进行评估，及时发现并纠正问题，提高决策的科学性和有效性。
在行政决策中，信息不对称问题是一个需要重视和解决的挑战。
政府部门应认识到信息不对称可能导致的不公平和不理想决策结果，并采取相应措施加以解决。

一、理论基础
1.信息不对称
1.1定义：信息不对称是指在市场经济活动中, 在相互对应的经济个体之间的信息呈不均匀、不对称的分布状态，由于各类人员对有关信息的了解是有差异的，掌握信息比较充分的人员，往往处于比较有利的地位,而信息贫乏的人员，则处于比较不利的地位。
也就是说行为人之间的这种信息占有的不同称为信息不对称，但其中要涉及到不同行为人之间发生契约关系，否则就无所谓信息不对称。
1.2 作用：由于市场中卖方比买方更了解有关商品的各种信息，掌握更多信息的一方可以通过向信息贫乏的一方传递可靠信息而在市场中获益，买卖双方中拥有信息较少的一方会努力从另一方获取信息，市场信号显示在一定程度上可以弥补信息不对称的问题，信息不对称是市场经济的弊病，要想减少信息不对称对经济产生的危害，政府应在市场体系中发挥强有力的作用。
这一理论为很多市场现象如股市沉浮、就业与失业、信贷配给、商品促销、商品的市场占有等提供了解释，并成为现代信息经济学的核心，被广泛应用到从传统的农产品市场到现代金融市场等各个领域。
具体来说，有如下作用：
1.该理论指出了信息对市场经济的重要影响。
随着新经济时代的到来,信息在市场经济中所发挥的作用比过去任何时候都更加突出,并将发挥更加不可估量的作用。
2．该理论揭示了市场体系中的缺陷,指出完全的市场经济并不是天然合理的,完全靠自由市场机制不一定会给市场经济带来最佳效果 ,特别是在投资、就业、环境保护、社会福利等方面。
3．该理论强调了政府在经济运行中的重要性,呼吁政府加强对经济运行的监督力度,使信息尽量由不对称到对称,由此更正由市场机制所造成的一些不良影响。
1.3影响：（1）当别人的选择关系到自身利益，而自己又不知道别人将如何选择的时候，理性人只能自顾自，这就是典型的“囚徒困境”。
在这个理论假设中，囚犯所面临的困境，是因为检察官有意不让囚犯沟通信息，否则，他与囚犯之间就信息不对称了，所以检察官有意为囚犯设定的信息不对称困境，其实是为了自己能够信息对称。
（2）因为不知道对方会作出什么选择，所以为此制定合乎自己利益最大化的规则，最终是不想得到的结果偏偏全得到了，这叫做“逆向选择”。
例如，企业中的管理者如果不知道应聘者是不是能干，多数都不会愿意出高价钱来聘用还不了解的新员工。
这一做法产生的直接结果，将使受聘者的才干普遍低于聘用者预先的期望值，而符合期望值的人反而不来了。
相似的例子：一是保险公司提高保价，本来是想贴补因理赔造成的损失，结果因此而来的投保人都是些真有风险的人。
“逆向选择”也被人们通常解释为“劣币驱逐良币”。
（3）由于市场的不确定性和分工细化，增加了人们获取信息的成本，信息不对称部分造成对当事人行为约束的弱化，人们追求利益最大化的机会主义的“机会”增加，从而产生道德风险。
信息不对称发生在交易契约签订之前，容易引发“逆向选择”。
信息不对称发生在交易契约签订之后，容易引发“道德风险”和“委托-代理问题”。
信息不对称现象在现代金融领域的表现更为普遍和突出,尤其在新兴市场和东南亚地区乃至中国大陆，企业骗贷、出口骗退和银行呆坏账的涌现，无不与此紧密相关。
2.逆向选择
1.1定义：所谓贸易自由化就是各成员方通过多边贸易谈判，降低和约束
关税，取消其他贸易壁垒，消除国际贸易中的歧视待遇，扩大本国市场准入度。
实现上述目标的途径是以市场经济为基础，进行贸易自由化。
自由贸易政策允许货物和生产要素的自由流动，在国际价值规律作用下，可以刺激竞争，鼓励发展，提高经营管理水平，促进世界性的分工和贸易发展，扩大市场；同时使消费者得到物美价廉的商品和服务服务贸易自由化。
服务贸易自由何一个国家的经济化是在经济全球化的基础上发展起来的，是贸易自由化在服务领域的具体表现。
当今世界任发展都离不开世界上的其它国家。
经济全球化和一体化的趋势势不可挡。
无论是北方还是南方都被全球经济纽带捆绑在一起。
发展中国家特别是我国作为发展中大国都必须要在贸易自由化的浪潮中迎接竞争和挑战。
1.2理论研究：乔治·阿克劳夫和迈克尔·斯宾塞、约瑟夫·斯蒂格利茨由于在“对充满不对称信息市场进行分析”领域所作出的重要贡献，信息不对称而分享2001年诺贝尔经济学奖。
这三名获奖者在20世纪70年代奠定了对充满不对称信息市场进行分析的理论基础。
其中，阿克尔洛夫所作出的贡献在于阐述了这样一个市场现实，即卖方能向买方推销低质量商品等现象的存在是因为市场双方各自所掌握的信息不对称所造成的。
斯彭斯的贡献在于揭示了人们应如何利用其所掌握的更多信息来谋取更大收益方面的有关理论。
斯蒂格利茨则阐述了有关掌握信息较少的市场一方如何进行市场调整的有关理论。
阿克劳夫、斯彭斯和斯蒂格利茨的分析理论用途广泛，既适用于对传统的农业市场的分析研究，也适用于对现代金融市场的分析研究。
同时，他们的理论还构成了现代信息经济的核心。
1.3意义：逆向选择理论深刻地改变了分析问题的角度，可以说给人们提供了逆向思维的路径，会加深市场复杂性的认识，由此能改变很多被认为“常识”的结论，使市场有效性理念又一次遭受重创。
由于信息不对称在市场中是最普遍存在的最基本事实，因而乔治·阿克劳夫(GeorgeAkerlof)的旧车市场模型具有普遍经济学分析价值。
他讲的故事虽然是旧车市场，可以延伸到烟、酒等所有产品市场、劳动市场和资本市场等等。
也能解释为什么假冒伪劣产品充斥这些市场，是因为交易双方的信息不对称，一方隐藏了信息。
逆向选择的理论也说明如果不能建立一个有效的机制遏止假冒产品，会使假冒伪劣泛滥，形成“劣币驱良币”的后果，甚至市场瘫痪。
二、实验目的
我们通过实验了解信息不对称市场的交易过程，了解不对称信息如何导致市场失灵，.理解有效信息传递如何解决次品问题。
我们认为信息经济学是基于对现有经济现象的实证分析得出的结论，对于解决现实中的问题还处于尝试性的研究之中。
例如，买者对所购商品的信息的了解总是不如卖商品的人，因此，卖方总是可以凭信息优势获得商品价值以外的报酬。
交易关系因为信息不对称变成了委托——代理关系，交易中拥有信息优势的一方为代理人，不具信息优势的一方是委托人，交易双方实际上是在进行无休止的信息博弈。
市场经济发展了几百年，都是处于不对称信息的情况之下，当人们没有发现信息不对称理论的时候，比如亚当·斯密的时代，市场并没有显示出多么的缺陷，斯密甚至把“看不见的手”推崇备至，自由的市场经济理论学者都宣扬市场的自由调节，反对对市场的干预。
信息经济学逐渐成为新的市场经济理论的主流，人们打破了自由市场在完全信息情况下的假设，才终于发现信息不对称的严重性，一夜之间，到处都是“柠檬”，研究信息经济学的学者因而获得了1996年和2001
年的诺贝尔经济学奖。
我们认为实验经济学的发展目的不仅仅只是限制于社会市场的运用，我们更深层次的目的时将其运用于生活，小到我们的生活习惯，大到我们生活的政治中心。
现在，我们把美国经济学者的信息理论引伸到政治领域，得出的结论就是：如果提拔干部的更高一级领导比群众掌握更多的信息，那么低质量的官员将会驱逐高质量的官员，政府中官员的质量和素质会持续下降。
这些年中国社会的表现完全证实了这一理论。
沈阳市政府一班人马全部腐败，可以说对信息对称理论的完全印证。
因此，我认为中国经济领域中的假冒伪劣问题要靠政治领域的改革来纠正。
只有将政府官员中的假冒伪劣清除出去，市场中的假冒伪劣才会减少。
因此，经济的问题就是政治问题。
而如何才能使政府官员的质量提高呢？只有采取竞选制，只有让新闻媒体充分发挥作用，只有让政党监督机制充分发挥。
不从根子上进行治理，那就只能做表面文章，对中国经济质量的根本好转无济于事。
三、实验准备
我们小组三人先对我们要进行的实验进行选择，最终确定实验的题目，在此过程中，我们对实验题目的选择十分用心，先是选择了风车的成本与产量的实验，但是由于后面的一系列工作无法进行，所以我们在后期又选择了信息不对称的实验，最终在9.28那天确定好了选题，并且共同商议和制定了实验的提纲
根据所列出的题纲，我们在接下来的一天进行了实验，信息对称市场交易实验，信息不对称市场交易实验，有效信息传递对不对称市场的影响。
三个实验分别对应三个不同的方面，列出所需的数据，读数据进行解读，分析，并且和专业人士进行沟通，组内成员的积极配合，完成最终的试验报告。
最后共同完成PPT的制作，完成实验报告。
