Financing,reputation and information disclosure quality in the Chinese market

In this article, we propose a theoretical model based on the reputation theory and hypothesize a positive relation between the information disclosure quality and the company’s refinancing decision. We collected data from the listed companies, which refinances in Shenzhen main board and SME board during 2006–2012, as a panel sample, and tested the hypothesis empirically. The results indicate that there exists a significant positive correction short-term relation between refinancing decision and the information disclosure quality, but in the long term the relationship between the information disclosure quality and refinancing decision is not significant.     

Product market deregulation and the US employment miracle

We consider the dynamic relationship between product market entry regulation and equilibrium unemployment. The main theoretical contribution is combining a job matching model with monopolistic competition in the goods market and individual bargaining. We calibrate the model to US data and perform a policy experiment to assess whether the decrease in trend unemployment during the 1980s and 1990s could be directly attributed to product market deregulation. Under our baseline calibration, our results suggest that a decrease of less than two-tenths of a percentage point of unemployment rates can be attributed to product market deregulation, a surprisingly small amount.     

A reconsideration of the impact of recalls on the market valuation of a product

This paper looks at the problem of determining the effect on the market valuation of a product of recalls due to safety defects when the analytical framework is misspecified. Using the car market, the results show that it is difficult, if not impossible, to distinguish the effect on the price of recalls from the impact of quality differentials among makes and models.     

浅析网上无形市场与传统专业市场的替代性与互补性

网上无形市场和传统专业市场的互替与互补取决于交易主体的理性选择。买卖双方会通过对网上交易的内生交易成本与两种市场交易方式的外生交易成本进行博弈比较来选择最优的流通方式,从而使不同交易制度间呈现出互替与互补状态。网上交易的内生交易成本量则由当该内生交易成本和降低其发生所造成的外生交易成本这两者的总和达到最低时的资源配置量所决定。

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

Giffen goods and market making

Summary. This paper shows that information effects per se are not responsible for the Giffen goods anomaly affecting traders demands in multi asset noisy, rational expectations equilibrium markets. The role that information plays in traders strategies also matters. In a market with risk averse, uninformed traders, informed agents have a dual trading motive: speculation and market making. The former entails using prices to assess the effect of error terms; the latter requires employing them to disentangle noise traders demands within aggregate orders. In a correlated environment this complicates the signal extraction problem and may generate upward sloping demand curves. Assuming (i) that competitive, risk neutral market makers price the assets or that (ii) uninformed traders risk tolerance coefficient grows unboundedly, removes the market making component from informed traders demands rendering them well behaved in prices.Received: 30 April 2002, Revised: 3 December 2003, JEL Classification Numbers: G100, G120, G140.Support from the Barcelona Economics Program of CREA and the Ente per gli Studi Monetari e Finanziari Luigi Einaudi, are gratefully acknowledged.

上市公司信息披露违规问题研究

证券立法的首要目标是保护投资者合法权益,公开、公平、公正原则是实现这一目标的根本保证,信息披露制度是实现这一目标的制度基础,也是证券市场监管制度的基石。在资本市场中,公司信息披露不仅对降低信息不对称和交易成本具有重要意义,而且是保护投资者和实现资源优化配置的关键所在。对投资者利益的保护,是通过公司的信息披露,投资者可以了解到被投资公司的经营状况,保障他们合法地获得上市公司、政府证券监管部门及其他市场主体可能影响证券价格变化的各种信息的权利。当前我国证券市场的信息披露还存在许多问题：诸如虚假信息披露、隐瞒信息披露、延迟信息披露,导致这些问题的原因很多,最为突出的原因是：我国公司股权结构不合理、会计准则与制度的缺陷、监管力度不够、法律法规不健全等。因此,完善我国证券市场信息披露,必须多管齐下。     

基于我国证券市场羊群行为的宏观与微观策略

证券市场的羊群行为是指投资者在证券投资中模仿其他投资者决策,在股票价格波动中追涨杀跌的行为.导致我国证券市场羊群行为的原因包括宏观和微观两个层面.为此,本文从宏观和微观两个层面提出抑制羊群行为的相应策略,即培育市场理性与培育理性投资主体两项对策.具体包括:完善信息披露制度;改善证券市场供求关系;完善合理的交易制度;规范证券公司"信息串联"行为;培育理性投资者等.以此来实现改善上市公司的信息披露质量,促进证券市场效率,以减轻羊群行为之害.     

Competition,product line length,and firm survival: evidence from the US printer industry

Adjusting product line length is one major strategy that firms employ to sustain their market position in competitive environments. This study extends extant literature on product line length by adding empirical results on the relationship between competitive intensity and product line length, and by examining the performance of firms that follow the suggested product line strategies. The analysis of data on 1849 printer products introduced by 342 manufacturers from 1983 to 2002 shows an inverted U-shaped relationship between competitive intensity and product line length, and firms following this pattern have a significantly lower hazard ratio of exit. These results confirm those discussed in the previous literature and provide evidence of the positive impacts of following such product strategies on firm survival.     

Performance of European insurance firms in the single insurance market

The deregulation and liberalization process towards establishing a single European financial market has some important implications for the insurance industries. Due to the increased competition, insurance firms have to adjust their costs and operate efficiently to survive in this new environment. This paper attempts to analyze the cost efficiency and scale economies in the single European insurance market. Considering the ongoing enlargement process of the EU, our sample includes the insurance industries of the major EU‐15, four new members and a candidate country, Turkey, over the period 1995–2005. We use the firm‐level financial data and estimate a stochastic cost frontier that controls for differences in environmental conditions. All insurance systems display significant levels of cost inefficiency. The results further indicate that there are significant economies of scale, particularly for small‐ and medium‐size insurance firms. Finally, the analyses suggest similar results for major EU countries, new members and the candidate.     

The power of market mood — Evidence from an emerging market

This article focuses on investor behavior and, consequently, the mood in the market. By using a self-organizing network we develop a model which tries to capture the market mood and serves as an indicator of the reasonableness of selling or purchasing securities. In this sense, the final result of this model is the same as in the model-type prediction of future stock prices, with the only exception being that one is not required to know the concrete future values of the selected security. This will indirectly support the hypothesis that psychological factors are an important (if not key) market driving force.

我国期货市场亟需期货投资基金

我国期货行业自进入21世纪以来取得了飞速发展,无论品种规模还是成交量都已位居世界前列,然而,在国外已经成为期货市场主力的期货投资基金在我国却难觅其踪。期货投资基金可以优化和改善投资组合,规避股市系统性风险,实现专家理财保护中小投资者利益。实际上,从市场规模、运作现状、风险控制、资金充裕度以及证券投资基金在我国发展的成功经验来看,我国已基本具备设立期货投资基金的基础。但期货投资基金毕竟是一个高风险的投资工具,国内对它的研究还比较薄弱,法律体系和监管机制仍待完善,产品的种类和活跃程度仍待加强,在基金公司的设立方式上仍需谨慎选择,对于期货投资基金亟需的高端综合型人才的培养都是我国急需解决的问题。     

中国大飞机市场预测分析

中国大飞机项目的成功在很大程度上取决于市场的开拓,尤其是国内市场的开拓。虽然大飞机公司的成立在一定程度上体现了政府的意志,但毋庸质疑其未来的发展与成功最终还是要落到市场上来。本文采用了市场营销中市场细分的思想,将国内的大飞机市场分成了三个子市场,然后利用需求量宏观预测模型对各个市场在2004-2022年之间民用客机需求量的增长进行了预测并进行了分析,得出的结论是2004-2022年之间,国内航空公司对于民用客机的需求量增长主要集中在150-250座的客机上,因此在大飞机公司发展的初期阶段,鉴于其技术与资金上的限制,可以将其生产主要集中在该子市场上,然后再求进一步的扩大与发展。     

Stable market structures from merger activities in mixed oligopoly with asymmetric costs

This paper examines endogenous merger formations in a mixed oligopoly. Applying the core as a solution concept, we analyze which market structure(s) remain(s) stable when three firms—two symmetric private firms and one inefficient public firm—are allowed to merge with each other in a mixed Cournot industry. We show that according to the value of the marginal cost of the public firm, there always exists a pair of share ratios of the owners of both the (pre-merged) public firm and the (pre-merged) private firm such that the market structure with the merger between the public firm and one private firm belongs to the core. When the initial market structure is a mixed triopoly, it can only be blocked when one public firm and one private firm merge. Furthermore, we conduct a similar analysis in a general mixed oligopoly with one public firm and n private firms.

Chinese competition and product variety of Indian firms

Using detailed firm-product-year data across manufacturing industries in India, and exploiting the exogenous nature of China’s entry into the WTO in 2001, we investigate the link between the impact of import penetration from China on the product variety of Indian manufacturing firms. We find: (i) robust and significant effects of product drop, with the effect coming only from competitive pressure in the domestic market; (ii) robust evidence of product drop or ‘creative destruction’ only for firms belonging to the lower-half of the size distribution; (iii) firms drop their peripheral/marginal products and concentrate on the core ones; and (iv) the result is strongest for firms producing intermediate goods. For an average Indian manufacturing firm, a 10 percentage point increase in India’s Chinese share of imports in the domestic market reduces the product scope of firms by 1.7–4.4%. In contrast, we find positive effects on product scope when firms are importing intermediate goods. We also find evidence of significant productivity effects and within-firm factor reallocation. Our results are consistent to a battery of robustness checks and IV estimation.
