Joint product signals of quality

Summary The relationship between product quality, signals, and the firm's optimal pricing policy has been given much attention in economics. The literature is extended in this paper by considering the signaling problem of a firm that jointly produces two commodities—one of known quality to consumers (a search good) and one of unknown quality (an experience good). The model presented employs a stylized reputation function, a linear cost structure, and linear demand schedules to produce two interesting insights. First, the search good's price can potentially be used as a signal of the quality of the experience good. Second, the price of a search good will depend upon whether it is jointly produced with another search good or an experience good or whether it is produced in isolation by a single product firm. Furthermore, evidence from a paper on gasoline pricing seems to support this contention.     

Accounting Quality,Stock Price Delay,and Future Stock Returns*

In frictionless capital markets with complete information and rational investors, stock prices adjust to new information instantaneously and completely. However, a substantial body of research studies information imperfections such as asymmetric information and incomplete information. Information imperfections potentially hinder timely price discovery and are likely associated with delayed stock price adjustment to information. Our first research question therefore is whether the quality of accounting information (or “accounting quality”) is one such information imperfection that is associated with cross‐sectional variation in stock price delay. We define accounting quality as the precision with which financial reports convey information to equity investors about the firm’s expected cash flows. Poor accounting quality is likely associated with higher expected returns through uncertainty about stock valuation parameters and incomplete information. Our second research question therefore is whether the accounting quality component of price delay is associated with higher future stock returns. Consistent with our hypotheses, the results show that poor accounting quality is associated with delayed price adjustment and higher future stock returns. Thus, accounting quality plays a role in timely stock price discovery.     

外生单向溢出效应下纵向差异化产品Cournot和Bertrand竞争均衡的比较研究

研究价格(Bertrand)和数量(Cournot)竞争模式下,单向溢出对企业质量选择、利润的影响。以纵向差异化市场结构为例,建立了基于单向质量溢出的不对称寡头竞争模型,运用赋值计算对模型的均衡解进行了比较分析,结论是:1给定溢出因子和学习效应的合理取值范围,领先和跟随企业的质量与利润在价格竞争下都小于数量竞争;2质量间的单向溢出效应、跟随者的学习努力都会导致领先者初始质量的下降,但在价格竞争时,这种"逆向选择"效应的程度较低;3跟随者的学习激励随着溢出效应的提高而降低,并不受竞争策略变化的影响。这些发现可以解释中国轿车产业竞争模式对合资和自主创新企业关系变化的影响。     

Social networks,rice value chain participation and market performance of smallholder farmers in Ghana

This paper examines the impact of rice value chain participation and social networks on smallholder farmers' market performance outcomes (paddy price, quantity of paddy traded, and net returns), using data from a recent survey of 458 smallholder rice farmers in northern Ghana. We employed a treatment effects model to account for potential selection bias associated with observable and unobservable factors. The empirical results reveal that smallholder farmers' participation in a rice value chain is associated with increased paddy price, quantity traded, and net returns. We also find that value chain participation decisions and market performance are positively and significantly influenced by social networks. The empirical results also suggest that sex, farm size, mobile phone ownership, and access to credit significantly increase paddy prices, quantity traded, and net returns of smallholder rice farmers in the value chain.     

融资约束、产品质量与出口目的地选择

文章将融资约束、产品质量引入异质性企业贸易模型,研究企业融资约束对其出口目的地选择的影响,并从产品质量的视角进行机制分析。理论模型推导得出企业生产率与其在低收入国家出口占比呈负相关关系,而融资约束的存在则强化了这种负相关关系。通过理论分析发现,生产率、融资约束对于企业最优产品质量选择的决策会产生相反的影响,在不同收入水平的国家对产品质量偏好不同的情况下,这种机制恰恰可能解释了企业出口目的地选择的差异。文章使用中国微观企业贸易数据,进行实证研究发现：融资约束与企业出口低收入国家贸易占比成正向关系,此外融资约束与生产率之间存在着调节效应,生产率的提高可以缓解企业由于受到融资约束带来的影响。     

国际化经营、机构投资者与股价同步性

文章研究了中国上市公司的国际化经营对股价同步性的影响,以及机构投资者在二者关系中所起的作用。结果发现,相对于非国际化经营公司而言,国际化经营公司的股价同步性较高;而国际化经营程度越高,股价同步性越低,且二者的反向关系会随着机构投资者持股比例的增加而增强。结论表明,上市公司提供的信息量、投资者获取信息的成本、投资者的理性程度及结构等因素都会影响投资者识别和区分特质信息和噪音的能力,进而影响股价同步性。     

Output price fluctuations,short-run profits and long-run industry size with input market equilibrium effects

Conclusions In this paper, input market equilibrium effects are incorporated into an analysis of output price fluctuations. In particular, it is shown that an increase (decrease) in output price may not necessarily lead to an increase (decrease) in the shortrun profit of a firm operating in a competitive product market. The firm's profit may not necessarily be convex in output price. Hence,ex-post flexibility in production does not guarantee the preference for price instability by risk-neutral firms. Finally, in longrun equilibrium, a mean-preserving spread in output price may increase or reduce the equilibrium number of firms.     

Unionization,market structure,and economic growth

This article investigates the macroeconomic effects of unionization in a Schumpeterian growth model with an endogenous product market structure and a unionized labor market. The endogeneity of the market structure and the trade unionism of the labor market interact and jointly determine the equilibrium unemployment, firm size, number of firms, economic growth, and distribution of income between workers and firms. We show that unionization governs the distribution of income between workers and firms and the unemployment rate, but it does not give rise to any growth effect on the economy. In addition, unionization discourages potential entrants and hence decreases the equilibrium number of firms. These results echo the empirical observation in the sense that unionization raises unemployment and alters the distribution of income between workers and firms, but it does not give rise to a significant, real impact on the firms’ investment and the economy‐wide growth.     

EQUIVALENCE OF COMPETITION MODE IN A VERTICALLY DIFFERENTIATED DUOPOLY WITH DELEGATION

This paper aims to examine the equivalence of competition mode in a vertically differentiated product market with the relative performance delegation. It demonstrates the equivalence of product quality and social welfare in this delegation game, irrespective of modes of product competition. In addition, in a three‐stage game of quality‐delegation‐quantity (or price), it shows that the delegation coefficient is different between high‐quality and low‐quality firms in an asymmetric vertical differentiated model, and a high‐quality firm makes better use of the delegation than a low‐quality firm.     

Production theory under uncertain inflation

Summary and Conclusions This paper examines Chen's [1980] model of asset valuation under uncertain inflation in order to derive a static and comparative static theory of production by a competitive firm. Given the value maximizing and the price taking assumptions, the firm behaves as a profit-maximizer. The sole effect of uncertain inflation is to distort the price structure. that is, the firm adjusts the expected price of an input or output to reflect the systematic risk of that price. Because a change in circumstances can affect the systematic risk of a given price, assessing the effects of a specific policy or event solely in terms of its effect on expected price can be misleading. Parametric variations affect the structure of certainty equivalent prices. Therefore, the comparative static derivatives of the value maximizing firm emerge as extensions of the comparative static derivatives of the profit maximizing firm under certainty. Many of these comparative static derivatives are of determinant sign. The effects of changes in market uncertainty and in inflation uncertainty, while they can be characterized mathematically, cannot be signed in the general case. Cross-sectional studies indicate wide variation in the effects of inflation, so that the preceding theoretical results appear plausible. Finally, in view of the wealth of static and comparative static results which can be derived from Chen's model, that model provides a convenient benchmark against which to judge other models. Precisely because of its simple nature, Chen's model is ideal for establishing limits of analysis.     

Expensing Versus Capitalization

We develop a theoretical framework to study the effects of expensing versus capitalization of investment expenditures on capital market asset prices, corporate investment, and investment efficiency. We use a two‐period model in which the financial reports at the end of the first period influence the price of the firm. In the first period, the current owner makes an investment decision that yields returns during the first and the second periods. We highlight the benefits and costs of the matching principle in GAAP and identify conditions under which less disclosure improves investment efficiency. We find that, in terms of investment efficiency, expensing beats capitalization if and only if the expected growth rate is high, the growth volatility is large, or the earnings persistence is small. We also offer testable empirical implications for accounting choice and for real earnings management.     

Pricing to market, firm heterogeneity and the role of quality

We build a pricing-to-market (PTM) model with firm heterogeneity, which allows for imperfect competition and market segmentation in the presence of flexible exchange rates, horizontal and vertical differentiation and different tastes of consumers in destination markets. We derive firm’s pricing behaviour in response to price and quality competition shocks. We show that there is PTM heterogeneity across firms if quality has a role. We empirically assess the main predictions of our theoretical framework on Italian firm-level data. We document that export-domestic price margins are significantly affected by price and quality competitiveness factors even controlling for foreign demand conditions, size, export intensity, destination markets and unobservables. Finally, we provide evidence of strong heterogeneity across firms in their reaction to price and quality competitiveness.     

Occupational Licensing of a Credence Good: The Regulation of Midwifery

A general theoretical and empirical model of the impact of regulation on supply and demand (prices and quantities) is developed in this paper. The regulation of midwifery services—of certified nurse-tnidwives (CNMs)—relative to obstetricians (OBs) is analyzed within this framework. Demand-side (quality assurance) effects are distinguished from supply-side (Stigler-Peltzman) effects in the model. Since both unambiguously predict a price increase, we focus on the regulatory impact on quantity. We find, within the empirical model, that while both effects are present, supply-restricting effects dominate quality assurance in the U.S. market for CNM services. When mean regulations are compared to minimum regulations in the sample, CNM births increase from just under 6% of all births to a little over 11%. On net, regulation reduces the quantity of CNM births.     

Transaction Costs and Exchange: Nine Case Studies of Australian and Malaysian Firms

This paper justifies theoretically and empirically the diversification behaviour of an importing firm when it chooses the mixture of potentially differentiated products of its major input under price uncertainty. The paper investigates an equilibrium relationship among three key explanatory variables, which are the expected price, the systematic risk of price, and monopolistic market power of the suppliers in the market. The theoretical section shows that there exists a conflict between the risk–diversification effect and the agent's preference over certain products when the importer chooses the vector of optimal quantity shares. The latter effect may disturb or even dominate the former, which can be represented in an equilibrium relationship similar to the framework of the CAPM. As an empirical application, the Chinese wheat import market is examined and analysed to answer the questions raised by the basic statistics.

Guilds, efficiency, and social capital: evidence from German proto-industry

This article considers recent economic theories about guilds in the light of evidence from a German proto-industrial region. The empirical findings cast doubt on views that guilds existed because they were efficient institutional solutions to market failures relating to product quality, training, and innovation. However, guilds did generate a 'social capital' of shared norms, common information, mutual sanctions, and collective political action. This social capital benefitted guild members, but harmed outsiders and the wider economy. The article concludes that economic theories of collective action and interlinked markets can explain why guilds were widespread while not necessarily being efficient.     

Auditor Reputation,Auditor Independence,and the Stock‐Market Impact of Andersen's Indictment on Its Client Firms*

In this paper, we study a broad sample of Arthur Andersen clients and investigate whether the decline in Andersen's reputation, due to its criminal indictment on March 14, 2002, adversely affected the stock market's perception of its audit quality. Because these reputa‐tional concerns are more of an issue if an auditor's independence is impaired, we investigate the relationship between the abnormal market returns for Andersen clients around the time of the indictment announcement and several fee‐based measures of auditor independence. Our results suggest that when news about Andersen's indictment was released, the market reacted negatively to Andersen clients. More importantly, we find that the indictment period abnormal return is significantly more negative when the market perceived the auditor's independence to be threatened. We also examine the abnormal returns when firms announced the dismissal of Andersen as an auditor. Consistent with the audit quality explanation, we document that when firms quickly dismissed Andersen, the announcement returns are significantly higher when firms switched to a Big 4 auditor than when they either switched to non‐Big 4 auditors or did not announce the identity of the replacement auditor. Our empirical results support the notion that auditor reputation and independence have a material impact on perceived audit quality and the credibility of audited financial statements, and that the market prices this.     

Daily price adjustments in the U.S. market for natural gas

A daily model of cash market for natural gas in the U.S. is presented and estimated over 1997. The model develops the notion that the expected rather than the actual amount of gas in storage (along with weather) and storage changes impact the current daily cash price. These notions are supported by the estimations presented. At the daily observation level, reported changes in storage levels are signals that actual consumption or production are either as expected and result in no price pressure or are not as expected and do result in price pressures.     

Does quality differentiation matter in exporters' pricing behaviour? Comparing China and India

The product quality dimension has been rarely mentioned as a factor explaining the heterogeneous pricing strategies of exporters. This could underestimate the degree of mark-up adjustment and the extent of incomplete exchange rate pass-through (ERPT) at a disaggregated level across products and destination markets. This paper investigates the role of quality differentiation in price discrimination using data for China and India's exports disaggregated at the 6-digit product level across destination markets. The paper adopts an empirical approach that incorporates gravity model explanatory factors and allows disentangling the effect of quality on trade prices and volumes from that of other sources of price variation. After excluding short duration export spells, China's export prices denominated in foreign currency terms increase with the yuan's depreciation, implying an increase in exporters' mark-ups, but they decrease as expected in the case of India. However, mark-up increases decline with product quality and destination market income, as the elasticity of demand perceived by exporters increases. These findings remain robust to different measures of quality, samples, specifications, and to the potential endogeneity of quality.
