This paper examines the relationship between stock splits and the ownership mix of firms. Previous studies suggest that firms issue stock splits to lower their stock price into an optimal range so small investors can more easily afford to buy round lots. The results of this paper show a positive relationship between stock splits and institutional ownership but no effect on the firm's number of shareholders. Thus, the percentage of shares owned by individual investors decreases after a stock split. The inverse relationship between institutional ownership and a firm's total assets suggests that small firms use stock splits to attract attention from Wall Street. 相似文献

This article demonstrates how a spurious regression problem caused by dividend persistence is compounded by a spurious correlation problem when the dependent and independent variables in dividend behaviour regressions are ratios composed of common component variables. This article utilises a simulation procedure to take account of these problems, with the findings implying that extreme care should be taken when using ratios as predictor or explanatory variables in time series regression. This article introduces a reformulated Lintner first difference dividend behaviour model that is not subject to spurious regression in which past prices predict subsequent changes in dividends. 相似文献

Research summary : Entrepreneurial start‐ups suffer high rates of business failure. Previous research on entrepreneurial failure has focused on two kinds of explanations: statistical and psychological. Statistical explanations attribute excess entry to random errors made by boundedly rational entrepreneurs attempting to estimate business opportunities in risky markets. Psychological explanations focus on entrepreneurial overconfidence and competition neglect. These explanations emerged independently and have not been tested or compared in the same study. In this experimental study, we distinguish entrepreneurial markets from other types of markets and test statistical and psychological hypotheses for all market types. We find that excess entry is significantly greater in small, risky markets than in other market types, and that confidence levels account for excess entry, over and above the effects of unbiased statistical errors. Managerial summary : How can we explain the fact that most entrepreneurial ventures fail within five years? Market risk, inadequate capital and inexperienced management certainly play a role. However, from an economic point of view, it seems odd that inexperienced, under‐funded people continue to engage in risky behavior that is widely known to fail. We conducted experiments that tested two explanations of entrepreneurial failure. The first explanation – the statistical hypothesis – argues that entrepreneurship involves high uncertainty, so random errors are inevitable and can produce excess entry (or under‐entry). The second explanation – the psychological hypothesis – says that entrepreneurs' mistakes are not random but skewed heavily toward excess entry; hence, their decisions are distorted by psychological factors such as overconfidence. Our experiments found support for both of these explanations. Random errors under uncertainty explained 60% of the excess entry in our experiments. However, the overconfidence hypothesis correctly predicted that excess entry exceeds under‐entry, and our psychological measures of overconfidence found support in the data. We also found that the markets that most often attract entrepreneurial investment – emerging markets with high uncertainty – were the markets most conducive to excess entry, due to a combination of psychological and market factors. Hence, we conclude that potential entrepreneurs should pay less attention to their own abilities and aspirations, and more attention to the external realities of competition in the marketplace.

We exploit the transparency of internal capital markets (ICMs) within insurance groups to investigate the activity and efficiency of ICMs within insurance groups. Specifically, we compare the relationship between internal capital transfers and investment to that between capital from other sources and investment. The ability to track the actual ICM transactions allows for more direct analysis of ICM activity than most previous studies. Consistent with theory, we find evidence that ICMs play a significant role in the investment behavior of affiliated insurers. We then use these detailed data to execute a more direct test of ICM efficiency than currently exists in the literature. Consistent with ICM efficiency, results suggest that capital is allocated to subsidiaries with the best expected performance. 相似文献

Limited data means that prior structure is needed when working with large demand systems. The cost function is a convenient
vehicle for generating demand systems incorporating such structure. While the cost function directly yields Hicksian demand
functions they will not usually have an explicit representation as Marshallian demand equations i.e. in terms of the observable
variables. With fast hardware and modern software, however, this need not hinder the estimation of the (implied) Marshallian
demand equations. This paper develops the formal theory for using cost functions in this context, and reports on initial trials
on the operational feasibility of the method.

Internal credit risk modelling is important for banks for the calculation of capital adequacy in terms of the Basel Accords, and for the management of sectoral exposure. We examine Credit Value at Risk (VaR), Conditional Credit Value at Risk (Credit CVaR) and the relationship between market and credit risk. Significant association is found between different Credit CVaR methods, and between market and credit risk. Simpler Credit CVaR methods are found to be viable alternatives to more complex methodology. The relationship between market and credit risk is used to develop a new model that allows banks to incorporate industry risk into transition modelling, without macroeconomic analysis. 相似文献

A time interval can seem longer or shorter in relation to clock time depending upon the stimulus information encountered, the internal states of the perceiver, and what is remembered. Temporal perceptions may have important commercial implications when a time interval is comprised of an ad, a shopping episode, a service encounter, or some other consumptive event. Because music is often used by marketers to fill time intervals, we used background music to manipulate stimulus characteristics (congruity of central and peripheral elements of radio ads) and arousal states of listeners in an experiment. Arousal was found to moderate the influence of stimulus congruity on perceived time such that congruity contributed positively to retrospective duration estimates among subjects exposed to soothing (versus arousing) music. We develop practical implications and directions for future research on antecedents and consequences of time perception. © 1996 John Wiley & Sons, Inc. 相似文献

A large literature has found positive associations between economic freedom and income, growth, and a variety of other desirable outcomes. This paper surveys the literature that seeks to explain the causes of economic freedom. Some of the most consistent findings in this literature are that current levels of economic freedom are strongly correlated with past levels; freer countries have more difficulty continuing to improve their economic freedom; democracy and political freedom are positively associated with economic freedom; and inequality is negatively related.

Integrated vulnerability assessment of ecotourism to climate change in Dana Biosphere Reserve,Jordan
Climate change has become a major threat to ecotourism in protected areas. This study aims to assess the vulnerability of the ecotourism system in Dana Biosphere Reserve (DBR), the major ecotourism destination in Jordan, to climate change. We conducted qualitative semi-structured interviews with key informants in DBR to assess climate change-related threats, their influence on natural resources, local communities and ecotourism's activities; and adaptation practices. The results indicate that DBR is highly exposed to multiple climate threats, specifically reduced precipitation, shifts in the rainy season, and increased frequency and intensity of drought. These changes are degrading the environment, shifting tourism seasons, and changing livelihoods and lifestyles of local communities. To mitigate these diverse consequences, DBR implements a range of environmental management, technical, educational and business management policies and practices. However, this vulnerability assessment, which addressed social, economic, and environmental impacts, provides a holistic understanding of the susceptibility of the tourism system to climate change and guidance for facilitating future adaptation. 相似文献
