Stock market reactions to related diversification moves by service firms seeking benefits from information asymmetry and economies of scope

Service firms may seek benefits from information asymmetry and economies of scope by diversifying. Each source of benefit is based on different underlying mechanisms and each is affected differently by implementation difficulties and service characteristics. Previous research, however, has not analyzed the relative performance effects of these two very different sources of benefits for related diversified service firms. Thus, this paper uses an integrative framework including these aspects to examine the relative performance effects of benefits from information asymmetry and economies of scope in service firms.     

Mixing and matching: Prospective financial sector mergers and market valuation

Which types of mergers are likely to be most productive for banks and other financial firms in the US? From a management perspective, mixing disparate firms may be difficult, but may offer significant gains from diversification. The opposite applies to matching similar firms. This paper considers life insurance, property and casualty insurance, securities, and commercial firms as potential matches for banks. It examines a measure of diversification gains from potential consolidation, based on option pricing, and a model of the “building blocks” of the industries, based on arbitrage pricing theory. The results identify potential diversification gains from virtually all combinations involving banking and insurance, which arise because common factors are combined in different ways and because insurance is already well diversified.     

Banks’ earnings: Empirical evidence of the influence of economic and financial market factors

The structure of income is a foremost address within research on banks’ performance, especially with regard to effects on the resilience of banks’ earnings. Indeed, given their central position in the economy, banks shall thrive to generate sustainable earnings and control for their potential volatility. Existing studies mostly consider the weight of non‐net interest income (nonNII) as opposed to the traditional NII income source. Such aggregated nonNII is found to increase earnings risk but more granular studies conflict. We propose an original investigation of the influence of economic and financial conditions on various income types, assuming that performance may actually be driven by both the income structure and external conditions. We focus European banks, which have long been allowed to diversify beyond retail banking. Out of a straight panel framework, we question if the influence of external conditions spreads to earnings components other than credit losses and trading income and if it does allow for diversification benefits among components. We find that each component actually evolves owing to its own equation. Furthermore, effects of single variables may cumulate over different components of earnings (e.g. GDP) or provide with diversification benefits. These effects are all the more important since they are not mitigated by operating expenses. Hence, over a regarded period, banks’ performance depends upon their structure of income and upon volatilities and correlations of influential variables. Besides controlling for ex‐ante volatility, our approach shows that a given structure of income is not necessarily more resilient than others but that selected non‐banking income may support a higher stability of Earnings     

Discussion of ‘Accounting Premium’ for IAS/IFRS and U.S. GAAP Vis-à-vis German GAAP”

Ernstberger and Vogler [Ernstberger, J. & Vogler, O. (2008-this issue). Analyzing the German Accounting Triad with an Enhanced Multifactor Model—‘Accounting Premium’ for IAS/IFRS and U.S. GAAP Vis-à-vis German GAAP. International Journal of Accounting.] employ the concurrent use of three distinct accounting-standard regimes (German GAAP; U.S. GAAP; and IAS/IFRS GAAP) in Germany as a foundation for evaluating the relation between accounting standard regime and equity-return attributes. They find that firms using U.S. or IAS/IFRS GAAP have higher betas but yield lower returns (cost of capital) relative to firms employing German GAAP. They also find that portfolios designed to isolate the return impacts of U.S. and IAS/IFRS GAAP relative to German GAAP are priced in a risk-factor-like fashion. In this discussion I suggest that a good bit of this empirical evidence is problematic. I also discuss the implausibility of information quality being priced in a Fama and French [Fama, E.F. & French, K.R. (1992). The Cross-Section of Expected Stock Returns. The Journal of Finance 47 (2): 427–465.] factor-like fashion. Finally, I introduce the importance of conditioning analyses of the relation between firm-level information quality and equity-market return (cost of capital) on the degree to which the shareholder base of a firm holds diversified portfolios.     

多元化战略与代理成本、公司业绩关系的实证研究

本文主要研究上市公司采取多元化战略后对公司代理成本及公司业绩的影响。许多学者对目前多元化折价现象进行了解释,认为由于内部资本市场的无效率导致了多元化公司的资源配置没有发挥着理论上应该具备的优势;很多学者从代理问题出发来解释多元化折价现象,但是针对代理成本与多元化程度的关系做实证检验就很少。验证多元化是否真的提高了代理成本,本文正是基于这一点来展开研究的。结论为代理成本与多元化程度成正比,公司业绩与多元化程度成反比。     

民营企业债务违约是内因驱动吗？——基于短贷长投和多元化经营视角的分析

不同于以往从外部因素的角度关注民营企业债务问题,本文从企业自身行为出发分析了民企债务违约是否由内因驱动。具体地,本文考察了短贷长投和多元化经营对民营企业债务违约的影响。结果发现,总体上短贷长投以及多元化程度提高了民企债务违约的可能性。从传导机制上看,短贷长投和多元化降低了企业的盈利水平、提高了过度负债、增加了代理成本,并通过以上三个渠道提高了企业债务违约的可能性。从异质性结果来看,信贷紧缩会加大短贷长投对债务违约的促进作用。对于政府支持的行业而言,短贷长投和多元化引发的债务违约问题更严重。最后,更多的短贷长投和多元化在决策得当情况下不会引发债务违约风险。本文的结果表明,民营企业债务违约主要是由内因驱动,即由企业在“求大”“上层次”的心理下实施的粗放式发展模式驱动。本文对于追溯民企违约的根源、精准施策进而更好地支持民企发展具有一定的启示。     

Farm diversification strategies in northwestern Spain: Factors affecting transitional pathways

The present paper identifies strategies that farmers have undertaken in northwestern Spain, an area characterized by late structural adjustment. For this study, a survey of over 559 farms has been conducted in four areas representative of different specializations and rural situations, from marginal to productive intensification. Farms have been categorized according to social and productive characteristics through a multivariable analysis. Four basic behaviors have been identified and connected with farm types and rural areas using a multiple correspondence analysis. These basic strategies were defined depending on whether investments have been made on farms to increase or intensify production and whether new on- or off-farm diversification activities have been introduced. This analysis allows us to assess transitional pathways for the future and to assume some consequences of farm behavior in connection with structural adjustments. Thus far, empirical evidence shows that the nature and main drivers of the diversification process are different from those in northern European areas. At the same time, a significant level of farm abandonment is registered.     

Diversification strategy,efficiency, and firm performance: Insight from emerging market

We investigate further the inconsistencies of the diversification-performance link by introducing efficiency as moderating factor. A data of 319 firms was used to conduct a panel data analysis excluding the financial sector industries and the results show three important findings. First, industrial diversification shows a significant contribution in performance improvement while international diversification shows no effect on performance. Yet, international-conglomerate shows a significant negative relationship with performance. Meanwhile, the efficiency results are contrary to our conjecture. We find that efficiency is a factor to enhance performance, but it is not the moderating variable on the diversification-performance link. This implies that the efficiency of the firm has no connection with the link between diversification and performance.     

Specialisation versus diversification: A simple model for tourist cities

By developing a simple general equilibrium structure, this paper compares the welfare effects of tourism specialisation and economic diversification in tourist cities. We discovered that tourist cities with limited carrying capacity easily suffer from side effects, particularly Dutch disease, when faced with rapid tourism growth. Therefore, such cities should actively use revenue that is generated from the booming tourism sector to pursue economic diversification for the sake of sustainable urban development.     

Conference Announcement

This paper presents a case study of a landslide that devastated a small rural community in the redwoods of northern California. This seemingly mundane event is used to explore several insights offered by recent literature on environmental risk, and illustrate the extent to which our reliance on modern, technologically complex industrial systems as the basis for risk scholarship may limit our understanding of the role of environmental risk in society. This landslide, and the political upheaval that followed it, point to the need for more rigorous sociological analysis of how hazards , rather than risks, are legitimated in political discourse through a process called 'normalization'; and of the complex of organizational structures of causation that encourage the development of risky situations, not only in modern technological systems, but in systems of society-environment interaction with a much longer history, such as the extraction and management of timber.
