Management succession and financial performance of family controlled firms   总被引:1,自引:0,他引:1  
This paper examines the immediate and long-term impacts on financial performance of 124 management successions within Canadian family controlled firms. When family successors are appointed, stock prices decline by 3.20% during the 3-day (−1 to +1) event window, whereas there is no significant decrease when either non-family insiders or outsiders are appointed. However, a cross-sectional analysis indicates that the negative stock market reaction to family successors is related to their relatively young age which may reflect a lack of management experience rather than their family connection per se. Investors are uncertain about the “management quality” of family successors who have less established reputations than more seasoned non-family insiders and outsiders. Non-family member appointments tend to follow periods of poor operating performance implying that there might be more scope for improvement when a non-family successor is appointed. Unlike the US sample in McConaughy et al. [McConaughy, D.L., Walker, M.C., Henderson, G.V., Mishra, C.S., 1998. Founding family controlled firms: efficiency and value, Review of Financial Economics 7, 1–19.], which indicates that the median percentage of votes held by controlling families is less than 15%, the Canadian sample indicates a more concentrated ownership with the median percentage of family controlled votes exceeding 51%. Of the firms in our sample, 62% use dual class capitalization to maintain control within the family.  相似文献

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.  相似文献

This paper considers the implementation of a nonstationary, heterogeneous Markov model for the analysis of a binary dependent variable in a time series of independent cross sections. The model, previously considered by M offitt (1993), offers the opportunity to estimate entry and exit transition probabilities and to examine the effects of time-constant and time-varying covariates on the hazards. We show how ML estimates of the parameters can be obtained by Fisher's method-of-scoring and how to estimate both fixed and time-varying covariate effects. The model is exemplified with an analysis of the labor force participation decision of Dutch women using data from the Socio-economic Panel (SEP) study conducted in the Netherlands between 1986 and 1995. We treat the panel data as independent cross sections and compare the employment status sequences predicted by the model with the observed sequences in the panel. Some open problems concerning the application of the model are also discussed.  相似文献

Current discussions about reforms to health and long‐term care miss the most important trends that should be influencing debate. With an ageing population that includes a higher proportion of people with manageable illnesses, health and care costs will rise. Reforms must ensure that existing government spending is used more efficiently and that it harnesses – rather than works against – private financing.  相似文献

Farm invasions in Zimbabwe have highlighted the pressing need for land reform throughout the southern African region. In South Africa, where the racial disparities in land holding are most severe, the events in Zimbabwe have raised the temperature of the land debate and led to calls for land invasions by some rural groups. The ANC-led government, facing criticism from both right and left for the slow pace of reform, has veered between strident defence of private property rights and threats to expropriate white farms. White farming interests have reacted differentially, with some progressive voices joining the calls for an accelerated reform programme. Current land reform policy in South Africa seems set to advance the interests of emerging black commercial farmers and tribal chiefs at the expense of the rural poor and landless.  相似文献

This paper proposes an extensive data simulation exercise on the likely impact of non-agricultural market access liberalization. The paper analyses real options for tariff cut reduction, special and differential treatment and the treatment of unbound tariffs. This paper also gives indications concerning the likely economic impact of this trade round of industrial market access negotiations on African economies. It shows that an ambitious tariff cut reduction formula would provide greater access to developed country markets for African producers. However, this kind of formula has a major drawback for African countries in the sense that it could accelerate the de-industrialization of African countries and limit incentives to diversify their economies.  相似文献

Conditional inference on 2 x 2 tables with fixed margins and unequal probabilities is based on the extended hypergeometric distribution. If the support of the distribution is large, exact calculation of the conditional mean and variance of the table entry may be computationally demanding. This paper proposes a single‐saddlepoint approximation to the mean and variance. While the approximation achieves acceptable accuracy for ordinary practical purposes, an alternative saddlepoint approximation is provided that gives much closer to exact results. It improves the accuracy of current approximations to up to more than four powers of ten.  相似文献
