Involuntary and voluntary managerial job‐termination hazard functions are estimated for English professional soccer for the period 1972–1997. A novel feature is the use of match‐level data, which reveals aspects of the hazard otherwise concealed by estimation using annual data. Short‐term fluctuations in performance strongly influence the involuntary termination hazard. The latter is also heavily dependent on the team's current league position relative to its position when the manager took charge, and on the win ratio over the entire spell. Managerial human capital attributes are found to have a greater influence on the voluntary rather than on the involuntary termination hazard. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

In South Africa the distribution of land rights remains a major manifestation and cause of injustice, only slowly affected by the constitutionally mandated programme of land restitution, redistribution and tenure reform. The Transformation of Certain Rural Areas Act 94, 1998 (Trancraa) is the first post-apartheid legislation to reform ‘communal’ land tenure. It applies to 23 former ‘coloured rural areas’ and was introduced in six areas in Namaqualand in the Northern Cape Province during 2001–2. In a different, contested process a Communal Land Rights Bill for the former ‘homelands’ was published in August 2002, adopted by Cabinet in 2003 and signed into law in July 2004. While the Communal Land Rights Act relies on ‘traditional councils’ with a majority of non-elected members, Trancraa was enacted in the context of the 1997 White Paper of South African Land Policy and focused on community choice and the role of municipalities. The consultative process in Namaqualand was driven by civil society organisations and community actors, but did not include the training, finance and development support needed to transform rural relations among people affected by unemployment, land scarcity and weak local organisations. To promote procedural and substantive justice, tenure reform must honour the human rights of equality, redress and land development support articulated in land policy and the Constitution. 相似文献

This study is the first to examine the predictive validity of the Karnani and Wernerfelt theoretical model. We developed measures for four variables, and explored whether they successfully operationalized the dimensions in the theoretical model. The model proposed four response strategies, and six were observed in the data. Incumbent firms most frequently did not respond at all to another firm's entry, even though a counterattack response was predicted by the model. Since the independent variables did not predict responses as proposed by the model, exploratory analyses identified “best” predictors of responses. 相似文献

While a significant literature has emerged recently on the longer-term effects of price promotions, as inferred from persistence models, there is very little if any attention paid to whether such longer-term effects vary across different types of consumers. This paper takes a first step in that direction by exploring whether the adjustment, permanent, and total effects of price promotions, and the duration of the adjustment period, differ between consumers segmented based on their usage rates in a product category and their loyalty to a brand. We also investigate whether such consumer segmentation will improve the forecasting performance of persistence models at both product category and brand levels. Expectations are developed based on consumer behavior theory on various effects of price promotions, such as the post-deal trough, the mere purchase effect, the promotion usage effect, and responsiveness to competitor's reactions. Evidence from household-level supermarket scanner data on four product categories is provided. We find substantial differences between consumer segments and provide insights on how managers can increase the longer-term effectiveness of price promotions by targeting each consumer segment with a different promotion program. In addition, consumer segmentation is found to significantly improve the forecasting performance of the persistence model for two of the four product categories. For the other two product categories, consumer segmentation provides forecasting performance similar to that obtained from aggregate-level persistence models. 相似文献

Should a seller with private information sell the best or worst goods first? Considering the sequential auction of two stochastically equivalent goods, we find that the seller has an incentive to impress buyers by selling the better good first because the seller's sequencing strategy endogenously generates correlation in the values of the goods across periods. When this impression effect is strong enough, selling the better good first is the unique pure‐strategy equilibrium. By credibly revealing to all buyers the seller's ranking of the goods, an equilibrium strategy of sequencing the goods reduces buyer information rents and increases expected revenues in accordance with the linkage principle. 相似文献

This paper derives an optimal reflationary mix for the next decade and comments on the industrial implications of this policy. The discussion is based on simulations of the multisectoral dynamic model of the UK economy developed by members of the Cambridge Growth Project. The results suggest that the concentration on macroeconomic policy alone may be misguided and that instruments which attack the roots of Britain's industrial problems should receive more attention. The paper also demonstrates that the optimal control procedure is a reliable tool for steering an economy towards a desired target trajectory and that this is feasible for very large econometric models. 相似文献

This paper explores the potential of tour guides to contribute to the protection of natural areas by educating their customers through interpretation and modeling environmentally appropriate behaviors. Applying Cohen's (1985) model of the guides' role, modified by Weiler and Davis (1993), as a framework, it examines the potential role that kayak tour guides can play in shaping the experience of visitors to one marine area, the Pacific Rim National Park. It uses two approaches to explore the perceptions of clients about the role of kayak guides using: (1) a pre- and post-trip questionnaire and (2) participant observation. Results indicate that five of the six roles were rated high in importance, but one role, the communication role, was not as important. Comparing performance with importance attached to each role revealed congruence with five roles, but lower levels of performance in relation to importance with the role of “motivator of responsible behavior”. Variability within all of the importance and performance measures suggest that for some individuals, performance did not match importance, highlighting the need to consider market segmentation in future studies. These findings are discussed within the ecotourism paradigm, and their implications for protected area management and for visitor behavior modification are considered. 相似文献
