Information Revelation and Market Incompleteness

This paper introduces a theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets. We analyse a simple security design model in which the number and payoff of securities are endogenous. Agents have rational expectations and differ in information, endowments, and attitudes toward risk. When markets are incomplete, equilibrium prices are typically partially revealing, while full relevation is attained with complete markets. The optimality of complete or incomplete markets depends on whether the adverse selection effect (the unwillingness of agents to trade risks when they are informationally disadvantaged) is stronger or weaker than the Hirshleifer effect (the impossibility of trading risks that have already been resolved), as new securities are issued and prices reveal more information. When the Hirshleifer effect dominates, an incomplete set of securities is preferred by all agents, and generates a higher volume of trade.

Imagery,Affect, and Financial Judgment

Traditional theories of finance posit that the pricing of securities in financial markets should be done according to the quality of their underlying technical fundamentals. However, research on financial markets has tended to indicate that factors other than technical fundamentals are often used by market participants to gauge the value of securities. This phenomenon may be quite prevalent in markets for initial public offerings (IPOs), where securities lack a financial history. The imagery and affect associated with securities can be a powerful basis upon which to judge their worth.

Advanced business students in a securities analysis course were asked to evaluate a number of industry groups represented on the New York Stock Exchange in terms of a set of judgmental variables. After providing imagery and affective evaluations for each industry group, the participants judged the likelihood that they would invest in companies associated with each industry. Imagery and affective ratings were highly correlated with one another and with the likelihood of investing. Judgments of performance correlated poorly to moderately with actual market performance as measured by weighted average returns for the industry groups studied. The results suggest that imagery and affect are part of a coherent psychological framework for evaluating classes of securities, but that framework may have low validity for predicting performance.     

中国证券公司退出机制问题探讨

随着我国证券市场的规范发展,由于历史原因,部分证券公司积聚的风险日益凸显,高风险证券公司的风险处置和市场退出,成为中国证券市场面临的重要课题。近年来,由于证券公司市场退出的法律机制不够完善,强制退出过程中存在行政主导、政策性强等问题。因此,完善我国证券公司市场退出机制,具有重要的现实意义。     

The influence of cultural distance on the volatility of the international stock market

Along with the development of cultural dimensions and cultural distance, the influence of cultural variables on the stock market is attracting more and more attention. In this study, we propose an improved gravity model to examine the relationship between culture and the volatility of the international stock market. Firstly, based on Hofstede's cultural dimensions theory, a model of the impact of cultural dimensions on the volatility of the national stock market is presented. Secondly, cultural distance is incorporated into the extended gravity model. Then, models of the impact of cultural distance on fluctuations in the international stock market and on foreign securities investment are proposed. Finally, the results of case studies using samples of national stock market indices indicate that different cultural dimensions have different influences on the volatility of national stock markets. The smaller the cultural distance between countries, the more similar the level of volatility in those countries' stock markets. Greater cultural similarity promotes increased securities investment between countries.     

Equilibrium in economies with incomplete financial markets

This paper analyses an exchange economy in the absence of Arrow-Debreu complete markets. It is assumed that trading takes place in the sequence of spot markets and futures markets for securities payable in units of account. Unlimited short-selling in securities is allowed. A general equilibrium in such an economy is a set of current and future prices (contingent on uncertain events) and a set of individual plans such that all markets are cleared. The existence of such an equilibrium is proved under usual assumptions. This is in contrast to the case of futures markets for contingent futures commodities where an equilibrium may not exist. The optimality of equilibrium allocations is also discussed.     

发达证券市场的层次化综合化及我国证券市场的路径选择

一国证券市场是层次分化还是综合统一取决于该国证券发行人的融资规模、成本和风险及投资者的理性程度.英美等国的证券市场比较成熟,其在市场层次极大丰富的基础上逐渐走向综合化,相比而言,我国现阶段的证券市场还不够成熟,不宜过于追求市场的综合统一,应加强市场的层次化建设.     

Pricing rules and Arrow–Debreu ambiguous valuation

This paper considers pricing rules of single-period securities markets with finitely many states. Our main result characterizes those pricing rules C that are super-replication prices of a frictionless and arbitrage-free incomplete asset structure with a bond. This characterization relies on the equivalence between the sets of frictionless securities and securities priced by C. The former captures securities without bid-ask spreads, while the second captures the class of securities where, if some of its delivers is replaced by a higher payoff, then the resulting security is characterized by a higher value priced by C. We also analyze the special case of pricing rules associated with securities markets admitting a structure of basic assets paying one in some event and nothing otherwise. In this case, we show that the pricing rule can be characterized in terms of capacities. This Arrow–Debreu ambiguous state price can be viewed as a generalization for incomplete markets of Arrow–Debreu state price valuation. Also, some interesting cases are given by pricing rules determined by an integral w.r.t. a risk-neutral capacity. For instance, incomplete markets of Arrow securities and a bond are revealed by a Choquet integral w.r.t. a special risk-neutral capacity.     

Risk Diversification on the Polish Capital Market

The basics of portfolio management theory and methods of efficient selection of assets and their financing have been created by Markowitz and Sharpe. They propose that risk diversification consists, generally speaking, of the increase in the number of securities in a portfolio. So, authors try to answer the question of how many securities have to be bought on a given market to assure a well-diversified portfolio, where the increase in the number of securities does not lead to a significant decrease in portfolio risk. To evaluate such a purpose on the Polish capital market, 20 companies were surveyed that are included in the WIG20 index in the period January 2–October 10, 2001. The returns were estimated on a weekly basis. The research shows that a portfolio of securities constructed, according to the Sharpe Model, has a wide application to the Polish capital market.*University of Szczecin—Poland.

Effects of US interest rates and news on the daily interest rates of a highly indebted emerging economy: evidence from Turkey

It has been widely demonstrated that asset prices react sensitively to macroeconomic news releases both in the industrialized countries and emerging markets. However, there are contradicting results on the effects of changes in interest rates of industrialized countries on asset prices of emerging markets. In heavily indebted economies, in addition to these factors, political news and announcements from international institutions that may increase or decrease concerns about debt sustainability can affect asset prices as well. This potential notwithstanding, there has been relatively limited empirical work on the effects of such variables. The objective of this study is to quantify the impact of all of these factors on interest rates of a highly indebted emerging economy. Using daily post-crisis data of the Turkish economy we show that both good and bad political news, International Monetary Fund announcements, and European Union related news significantly affected secondary market government securities yields, whereas volatility of yields was affected mainly by bad news releases. Changes in US Treasury bond rates and ‘appetite’ for risk of foreign investors did not affect government securities yields in the period analysed.     

The impact of news,oil prices,and global market developments on Russian financial markets1

This paper analyses the impact of news, oil prices, and international financial market developments on daily returns on Russian bond and stock markets. First, regarding returns, energy news affects returns, while news from the war in Chechnya is not significant. Market volatility does not appear to be sensitive to either type of news. Second, a significant effect of the growth in oil prices on Russian stock returns is detected. Third, the international influence on Russian financial markets depends upon the degree of financial liberalization. The higher the degree of financial liberalization, the stronger is the impact of US stock returns on Russian financial markets. In addition, banking reform and interest rate liberalization efforts seem to dictate the globalization of Russian stock markets, while it is the progress in liberalizing securities markets and non‐bank financial institutions that matters more for the globalization of Russian bond markets.     

香港和内地证券市场的动态竞争关系研究——基于A+H交叉上市公司的实证分析

交叉上市引起不同证券市场对有限投资者和资金资源的竞争。文章在阐述证券市场竞争的Lotka-Volterra模型基础上,通过2006-2010年38家A+H交叉上市企业的日交易数据实证分析了香港和内地证券市场之间的动态竞争过程。结果表明,两市场之间的动态竞争关系从交叉上市初期的捕食—诱饵关系逐步演化为目前的竞争互惠关系,且这种动态演化过程与企业交叉上市顺序没有显著的相关性。这说明内地证券市场正在不断完善,鼓励企业境外上市和A股回归将有利于内地证券市场的发展,而且互惠合作应是未来证券市场竞争的发展趋势。     

Uncertainty and insurance in strategic market games

Summary. For perfectly competitive economies under uncertainty, there is a well-known equivalence between a formulation with contingent goods and one with state-specific securities followed by spot markets for goods. In this paper, I examine whether this equivalence carries over to a particular form of imperfect competition. Specifically, I look at three Shapley-Shubik strategic market games: one with contingent commodities, one with Arrow securities traded under imperfect competition and one with Arrow securities traded under perfect competition. First I compare the feasibility constraints of these three games. Then I compare their equilibrium sets. As in Peck and Shell (1989), the only common equilibria between the first and the second game are those which involve no transfer of income across states. However, if the securities markets are competitive, then the set of equilibria of the contingent commodities game and the securities game coincide.

Tipping the (Im)balance: Capital inflows,financial market structure,and banking crises

An emerging consensus among scholars and policy‐makers identifies foreign capital inflows as one of the primary determinants of banking crises in developed countries. We challenge this view by arguing that external imbalances are destabilizing only when banks face substantial competition from securities markets in the process of financial intermediation. We assemble a dataset of banking crises covering the advanced industrialized countries from 1976 to 2011 and find evidence of a conditional relationship between capital inflows, a well‐developed securities market, and the incidence of banking crises. We further explore the impact of capital inflows on banks’ actual risk taking as indicated by their capital adequacy levels and measures of insolvency risk. Our results demonstrate that prudential capital cushions tend to decline with the combination of capital inflows and prominent securities markets. We highlight the political decisions—often made during the early days of a country's financial development—that determine the relative prominence of banks vs. non‐bank financial institutions and conclude with policy recommendations.     

基于期权思想的融券费率定价方法研究

证券融资融券交易是成熟证券市场普遍实施的一种交易制度。融券与融资不同,其标的不是资金而是证券,但两者都是信用业务,需要为相关交易支付一定的费用,融资的利率相对容易确定,而融券费率则比较复杂一些,目前各类管理规定中对此并没有明确的说法。本文借鉴了我国台湾地区的经验,计算出我国大陆地区试行融资融券可行的融券费率。     

Evaluation of Selected Methods of Classification for the Warsaw Stock Exchange

The portfolio analysis allows a complex analysis of all the securities and it is connected with diversification of the portfolios risk. The problem that arises before the portfolios will be constructed and is connected with database of securities—what generally simplifies selection securities to portfolios. In a way of building database can be useful a taxonomic methods. The main aim of the paper is researching stability classifications for proposing methods and verification how different or similar they are. Such an approach in analysis of classification stability gives more information about researching companies and their financial or economic stability. It also gives information about the Polish capital market. In addition, such analyses are useful in making investment decisions, particularly in selection companies to portfolio.

On the Non-Existence of Redundant Options

In a seminal paper, Ross (Q J Econ 90:75–89, 1976) shows that if security markets are resolving, then there exist (non-redundant) options that generate complete security markets. Complementing his work, Aliprantis and Tourky (2002) show that if security markets are strongly resolving and the number of primitive securities is less than half the number of states, then every option is non-redundant. Our paper extends Aliprantis and Tourky’s result to the case when their condition on the number of primitive securities is not imposed. Specifically, we show that if there exists no binary payoff vector in the asset span, then for each portfolio there exists a set of exercise prices of full measure such that any option on the portfolio with an exercise price in this set is non-redundant. Since the condition that there exists no binary payoff vector in the asset span holds generically, redundant options are thus rare. I am grateful to an anonymous referee for very helpful comments.

Liquidity risk and bank portfolio allocation

The joint existence of a lender of last resort and of a stock market is usually considered the sign of a developed financial infrastructure. This paper analyzes whether a securities market may play a role similar to that of a lender of last resort by being of assistance to a bank, which faces possible liquidity shortages. We examine which of these two institutions best prevents a bank's liquidity shortages while allowing the optimal allocation of the bank's resources. Our results suggest that securities markets matter more for the liquidity of banks than a lender of last resort.
