连接外部性、横向联盟和市场竞争

分析了横向关系的双寡头企业具有连接外部性条件下的联盟决策,得出结论,横向企业的联盟降低了企业自身的成本,同时也降低了竞争对手的成本,具有正的连接外部性。企业先决定是否联盟,然后在市场上进行竞争;证实了市场竞争比较缓和时,横向企业联盟;市场竞争比较激烈时,横向企业不联盟。当存在产品差异化时,结论仍然不变;比较了企业联盟决策和社会计划者决策,论证得出市场竞争比较缓和时,企业和社会计划者联盟决策一致;市场竞争比较激烈时,企业联盟决策背离社会计划者的决策。     

Cartelizing effects of horizontal shareholding interlocks

Some models of industries with horizontal shareholding interlocks are generalized. First, we consider industries where firms exhibit different technologies and more general market demand functions. The cartelizing effects of financial interlocks are examined using both the Lerner index and the Herfindahl–Hirshman index. Furthermore, the model is extended to consider multiproduct oligopolies. We find a compact expression for the Lerner index and study the cartelizing effects of such an industry. Copyright © 2001 John Wiley & Sons, Ltd.     

Comparative statics for profit-maximizing and labor-managed cournot oligopolies

Comparative static results are derived for two types of oligopoly: profit-maximizing and labor-managed Cournot oligopolies. After establishing a general principle for comparative statics for oligopoly, we will examine how a shift in the demand function, changes in the wage rate, indirect tax rates and fixed costs, and technical change affect the equilibrium Cournot industry and firms‘ outputs, firms’ profits and dividends per unit of labor. We will also analyze the effects of entry. Our analysis makes an extensive use of the relationship existing between an individual firm's and industry outputs. We will derive two kinds of stability conditions: one behavioristic and the other computational. Finally, we will conduct comparative static analysis for mixed oligopoly where several profit-maximizing and labor-managed firms co-exist.     

融资约束对企业生产率的影响——基于系统GMM方法的国企与民企差异检验

本文基于2003～2009年中国制造业上市公司面板数据,运用附加融资约束变量的增广生产函数和系统广义矩估计方法,研究国企和民企资金可获得性在影响生产率方面的差异。结果发现,上市公司生产率从总体上看不受制于内源融资,但按所有制分类后,只有民企存在融资约束并显著影响生产率,生产率高的民企通常拥有丰裕的内源资金;进一步按流动性与负债状况分类后仍不改变结论,而且流动性差、负债率高的民企所受约束更加严重。     

The effects of listing changes between NASDAQ market segments

This study analyzes the effects of listing changes within NASDAQ market segments during the period of 1998 to 2005. We find that firms phased up from the NASDAQ Small Capital Market (SmallCap) to the NASDAQ National Market (NNM) experienced significant declines in bid-ask spreads, the volatility of returns, and the probability of informed trading, and firms that phased down from NNM to the SmallCap experienced decreases in bid-ask spreads, but insignificant changes in the volatility of returns and the probability of informed trading. We also estimate simultaneous equations models of bid-ask spreads, return volatility, and trading volume for both groups of firms. The results confirm that improved liquidity is associated with the listing changes for the phase-up firms. However, the simultaneous equations model suggests that the decreases in bid-ask spreads for the phase-down firms are caused by the changes in share prices.     

Capital Market Imperfections, Uncertainty and Corporate Investment in the Czech Republic

In this study we examine private investment behavior of firms in the Czech Republic. A special feature of the study is that the investment equations include variables which may give some more insights into the role of capital market imperfections as well as the effect of uncertainty. Our results find support for the accelerator model. We find evidence for cash-flow effects on Czech corporate investment. It is striking that indeed smaller longer privatized firms face relatively less cash flow restrictions. Financial structure doesn't matter as much as we expected. We find that smaller firms react positively to more uncertainty.     

Heterogeneous players in a Cournot model with differentiated products

In this article, we analyse a duopolistic Cournotian game with firms producing differentiated goods, marginal costs are constant and demand functions are microfounded. We consider firms adopting different decisional mechanisms which are based on a reduced degree of rationality. In particular, we assume that a firm adopts the local monopolistic approximation approach, while the rival adjusts its output level according to the gradient rule. We provide conditions for the stability of the Nash equilibrium and investigate some bifurcation scenarios as parameters vary. The main finding of the article is that both a high level and a low level in goods differentiation may have a destabilising role in the system.     

The effectiveness of more advanced human resource systems in small firms

In this paper, we analyze whether Human Resource (HR) systems in small firms can be associated with higher performance as well as higher wages. Our study, which focuses on Dutch pharmacies, shows that more advanced HR systems do not have any effect on firms' productivity. In these micro firms, it is only employees who significantly benefit from the introduction of both a basic and a more advanced HR system. Our findings that small firms do not significantly benefit from introducing less traditional HR practices offer an explanation for the thresholds in the diffusion of these HR practices in small firms, and suggest that in these firms formal HR practices are less important than personal relations between the employer and his or her employees.     

Technological opportunity and the relationship between innovation output and market structure

This study examines influences of technological opportunity on the relationship between market structure and the innovation output of different‐size firms. A simultaneous‐equations model is specified and estimated separately for technologically progressive and technologically unprogressive industries. The study finds that innovation activities of small firms and large firms bear different relationships to market structure, in part resulting from interindustry differences in technological opportunity. In technologically progressive industries, innovation output (especially of small firms) is lower in the presence of high concentration and is increased substantially by high R&D intensity. Large‐firm innovation output has a positive effect on industry concentration, but only in technologically unprogressive industries. Copyright © 2005 John Wiley & Sons, Ltd.     

The impacts of family involvement on R&D investment intensity in firms: Evidence from China

Drawing on the perspective of socioemotional wealth, this paper explores the types of family involvement in family firms and their impacts on R&D investment intensity. Using data from the forecasts issued by A-share family firms listed on Chinese stock markets between 2008 and 2019, the study finds that the separation of ownership and control is negatively associated with R&D investment intensity in non-high-tech firms, whereas potential gains of socioemotional wealth from R&D activities by high-tech firms produce a positive influence that offsets the negative impact of the separation of ownership and control on R&D investments. It reveals the importance of gains of socioemotional wealth. In contrast to the separation of ownership and control, family involvement in management is negatively associated with firms’ R&D investment intensity in both high-tech firms and non-high-tech firms. Our results capture the diversity of family members’ identity recognition, which leads to family members’ different evaluations of the potential gains and losses of socioemotional wealth. Overall, the distinction between high-tech family firms and other family firms is shown to be significant, as is the distinction between the impacts of different types of family involvement.

     

On the Relationship between Voluntary Disclosure,Earnings Smoothing and the Value-Relevance of Earnings: The Case of Switzerland

Abstract

This paper examines whether voluntary disclosure by Swiss firms constrains the use of discretionary accruals to smooth earnings, and explores the effect of voluntary disclosure on the value relevance of earnings. We focus on Swiss firms because Switzerland's financial reporting system provides managers with extensive discretion in corporate disclosure, and there are important variations in the level of information provided in their annual reports. We consider that managers can choose two different ways to voluntarily convey information, either through the quality and quantity of annual report disclosure or, through compliance with International Accounting Standards (IAS)/International Financial Reporting Standards (IFRS) or US Generally Accepted Accounting Principles (GAAP). Relying on a simultaneous equations approach, our results suggest that Swiss firms use discretionary accruals to smooth earnings. However, this relation is reduced for firms that voluntarily disclose more information in their annual report or comply with IAS/IFRS or US GAAP. Moreover, we show that discretionary accruals of high disclosers or of firms voluntarily complying with IAS/IFRS or US GAAP receive a lower valuation weight.     

IPO performance and the size effect: Evidence for the US and Canada

This study provides new evidence on the interaction between firm size and IPO underpricing in the US and Canadian markets. We find a size effect on IPO underpricing in both Canada and the US, which is larger for Canadian firms. Canadian small firms show more underpricing than US small firms (19.32% vs. 13.87%). Large Canadian firms also exhibit more underpricing than their US counterparts over the sample period (12.83% vs. 10.09%). A size effect on performance is not apparent for holding periods beyond six months from the IPO in both countries, consistent with seasoning effects that reduce information asymmetries across firms over longer investment horizons.     

The R&;D and productivity relationship of Korean listed firms

This study analyzes the relationship between R&D investment and the productivity of Korean R&D-engaged firms. An interdependent chain of equations including the propensity to invest, R&D investment and productivity are estimated in a multi-step procedure accounting for selectivity and simultaneity biases. Using Korean firm level panel data of listed firms from 1986 to 2002, we find four main empirical results. First, there is a two-way causal relationship between R&D investment and productivity for Korean listed firms. Second, Chaebol firms were associated with lower R&D growth as well as lower labor productivity growth in comparison to non-Chaebol firms. Third, there was a substantial reduction in growth rates both in R&D investment and labor productivity in 1997-1998, immediately following the Asian financial crisis. Fourth, considering the positive feedback effect from productivity growth to R&D growth, a decrease in R&D investment growth after the Asian financial crisis should have been harmful by further decreasing productivity growth.     

Market Risk Disclosures and Investment Efficiency: International Evidence from the Gulf Cooperation Council Financial Firms

This study examines the association between market risk disclosures (MRDs) and the investment efficiency of financial firms from six emerging markets in the Gulf Cooperation Council (GCC) region. Based on a sample of 553 firm‐year observations over the 2007–2011 period, we find that MRDs are significantly and negatively associated with both under‐investment and over‐investment and that this association is more pronounced for larger firms. We also find that the association between MRDs and under‐investment is moderated during periods of economic distress such as the Global Financial Crisis of 2008 and that the association between MRDs and over‐investment is magnified during periods of reduced financial distress. Our results are consistent with the idea that MRDs reduce information asymmetry, which ultimately improves investment efficiency. We contribute to the literature in an emerging market context by providing empirical evidence on the association between MRDs and investment efficiency across six emerging GCC capital markets. This study also fills a gap in the literature by providing evidence on the factors affecting the investment efficiency of financial firms.     

The role of accelerators in firm survival: An fsQCA analysis of Italian startups

Accelerators are a recent yet rapidly growing phenomenon within entrepreneurial ecosystems. The distinctive characteristics exhibited by accelerators, relative to previous incubation models, imply that accelerators may play a different role and have a different impact on the survival rates of participating firms. In this study, we explore the relationship between participation in an accelerator program and firm survival using fuzzy-set qualitative comparative analysis (fsQCA) with key variables related to firm survival. We analyze 38 accelerated startups from five Italian accelerators and a control group of 38 non-accelerated Italian startups. Our findings support the business accelerator literature that regards accelerators as a new and distinct generation of business incubators. Our results suggest that participation in accelerator programs on its own does not influence firm survival. However, we found a relationship between firm survival and accelerated technology-based firms that do not export and between firm survival and accelerated firms in the service sector with a small team that do not export. We conclude that factors affecting the survival of accelerated firms are different from factors affecting the survival of incubated firms, providing further evidence of the characteristics that distinguish accelerators from incubators.     

Enforcement Releases,Firm Characteristics,and Earnings Quality: Insights from Germany's Two‐tiered Enforcement System

The implementation of a two‐tier external enforcement mechanism in Germany in 2004 permits the examination of the interrelationship of enforcement releases, firm characteristics, and earnings quality in a unique institutional framework. A total of 151 cases are examined where the announcement of errors in prior disclosed and audited financial statements was mandatorily ordered by the enforcement authority. Prior literature documents the correlation between underperformance in financial ratios and the probability of erroneous disclosure of financial statements. Evidence is provided of differences in characteristics between firms with enforcement releases and control firms as well as all German publicly listed firms. The research affirms the connection of financial ratios to earnings quality metrics. Overall, the results document the underperformance in important financial ratios as well as indicate an inferior earnings quality of firms subject to enforcement releases vis‐à‐vis the control groups. These results hold with regard to both different earnings quality specifications and different periods observed. This study adds to the earnings quality discussion and contributes to the development of a comprehensive picture of accounting quality in the unique institutional settings of Germany. The findings show that a conjoint two‐tier public and private enforcement system is effective and could be a model for consideration by other countries.     

Gender Roles and Organizational HR Practices: The Case of Women's Careers in Accountancy and Consultancy Firms in China

The Chinese finance industry has experienced significant expansion both within the state sector and into the private sector. Professional consultancy firms have also emerged as a result of the rising interest in the outsourcing of accounting and management services. However, the study of women's careers in the accountancy profession in contemporary China remains largely an uncharted territory. Drawing on data from 69 interviews with auditors in five firms, this article investigates the nature of work of external auditors in China and how women auditors view their work‐life choices and constraints. We explore the likely differences between male and female auditors in their career aspirations and the extent to which these self‐perceived differences are informed by social conventions of gender role, organizational practices, and personal preferences. The study has strong implications for human resource management in professional service firms in China, with particular reference to job design, work organization, career support, and work‐life balance initiatives. The study contributes to the debate on gender, employment, and career development in the accountancy profession in different parts of the world. © 2013 Wiley Periodicals, Inc.     

The moderating effects of knowledge characteristics of firms on the financial value of innovative technology products

The development of innovative technology products is both costly and risky, and their economic value is highly uncertain. Based on a sample of 312 innovative technology products introduced between 1987 and 2006 in the U.S. and a long-horizon event study with control firms, we study the impact of innovative technology products on the long-term financial performance of a firm. In particular, we examine how the knowledge characteristics of the firm, which embrace its knowledge absorptive capacity, knowledge impact, and knowledge diversity, moderate such an impact. We find that on average an innovative technology product increases the firm's return on assets (ROA) (relative to control firms) by 2.18% in the second year after product introduction. However, the value of an innovative technology product varies with the knowledge characteristics of the firm that invented it. We find that the financial impact of technology products is stronger when firms have higher knowledge absorptive capacity, and more impactful and less diversified knowledge (as measured by patents). We classify firms into three categories based on their knowledge characteristics. We find that firms with a high knowledge fit increase their ROA by 4.55% after product introduction, while those with a low knowledge fit receive no benefit from the innovative technology products at all.     

Is your open-innovation successful? The mediating role of a firm's organizational and social context

Open firms are not equally successful. This is because, in order to benefit from external sources of knowledge, firms must be able to absorb such knowledge. The paper outlines a firm's context as a set of organizational and social features, which may be considered absorptive capacity antecedents. It explores the mediating role of such antecedents in the relationship – hitherto insufficiently researched – between the degree of openness and innovative performance. The use of a methodology combining both direct interviews and survey of Italian firms has allowed us to confirm the supposed mediating role. We also identify different modes for companies to open up their innovation process and, for each of them, the antecedents that are consistent with choices regarding the degree of openness.     

The impact of lead time on capital investments

We study equilibrium investment strategies of firms competing in stochastic dynamic market settings and facing two types of investment structures: investment with significant lead time (or time-to-build) and investment without (or minor) lead time. We investigate how investment behavior changes when investment is subject to time-to-build versus when it is not. We characterize equilibrium investment strategies under several information structures and compare results to the social optimum. We offer some new results. The model predicts that, controlling for demand, and production and investment costs, investments and outputs can be higher in progressive industries (which often exhibit time-to-build) than in fast-paced industries (where time-to-build is insignificant). Furthermore, for both investment types (investment with or without time-to-build) we offer a novel equilibrium in which firms incrementally invest. This behavior is driven by demand uncertainty and capacity constraints. Also, expected outputs are lower than Cournot outputs as firms face uncertainty. Moreover, the amount of uncertainty has different effects over investment types.
