Since 1970, over forty empirical studies have examined the performance consequences of formal strategic planning. This line of research has drawn heavy criticism from reviewers on methodological grounds, and has produced confusing, apparently contradictory results. This article reevaluates the planning-performance relationship from a resource perspective, arguing that strategic planning does not satisfy the criteria for sustainable competitive advantage– although it may produce economic value, it is easily imitated and may be substitutable. The article suggests that previous studies produced inconsistent results because they did not account for the dissemination of strategic planning over time, or for industry differences in strategic planning factor markets. An empirical test in two industries finds that formal strategic planning and financial performance are unrelated in a ‘planning equilibrium’ industry, but positively related in an industry with strategic planning factor market imperfections.  相似文献

The economics of land transfer and title insurance   总被引:3,自引:0,他引:3  
In the presence of uncertainty over the title of land (due to fraud or error), a legal system can protect either the current (innocent) owner, or a previous owner who claims title. The predominant system in the United States generally awards title to the latter in the event of legitimate claim. Thus, current owners frequently purchase title insurance to provide indemnification in the event of a loss. In contrast, the Torrens system awards title to the current owner, but provides for indemnification of any legitimate claimants. We evaluate these two systems and argue that if transaction costs are low, both promote efficient assignment of title (according to the Coase Theorem), but if transaction costs are high, the Torrens system is more likely to award title to the party that values it the most (namely, the current possessor).  相似文献

Medic (Medicago spp.) pastures are widely grown in rotation with dryland cereal crops in Mediterranean climate zones of Australia. Attempts since the 1960's to introduce this system to Mediterranean west Asia and north Africa (the native region of medic) have not lead to significant adoption; farmers in the region recognize medic, but as a weed and natural pasture plant. This first detailed economic evaluation of the rotational medic system was conducted using a whole-farm linear programming model based on the agricultural system of north-west Syria. The model represents in detail impacts of rotation on yields, labor requirements of alternative farm activities, availability of family and hired labor, subsistence income requirements, livestock feed sources and uses at different times and a choice of sheep stocking rates. Biological data for the analysis are based on a large six-year cropping and grazing experiment near Aleppo on terra-rossa soil with rainfall mainly in winter and averaging about 330 mm annually. The trial compared a dryland medic-wheat system and traditional two-year rotations of wheat with: fallow, watermelon, lentil and vetch. Results indicate that, given current prices and yields from the trial, medic is less profitable than traditional rotations. The model was used to investigate situations in which medic would be economically preferred. Selection of a medic rotation by the model was found to be particularly sensitive to the area of the farm and the price of labor. On small farms, labor availability per hectare is high, favouring the production of labor intensive crops such as lentil and watermelon. On larger farms, labor costs of these enterprises are substantial, increasing the relative profitability of medic, especially if labor prices increase. Interestingly, the relative desirability of medic is more sensitive to its impact on subsequent wheat crops than to the level of pasture production. We also found that modest increases in the prices of sheep products (especially milk) have a major impact on the economic performance of medic. These insights will allow improved focusing and targeting of future research and extension activities.  相似文献

Although many challenges remain, business ethics is flourishing in North America. Prominent organizations give annual business ethics awards, investments in socially screened mutual funds are increasing, ethics officers and corporate ombudspersons are more common and more influential, and new ideas are being tested in practice. On the academic side, two major journals specializing in business ethics are well-established and other major journals often include articles on business ethics and new organizations emphasizing ethics have been initiated. Within business schools, the number of endowed chairs is growing and the ethics curriculum is expanding. Canada is a major player in the business ethics discipline while business ethics in Mexico is just beginning to emerge as a focus of interest in both the business and academic communities.  相似文献

Search and Liquidity in Single-Family Housing   总被引:5,自引:0,他引:5  
A two-stage least squares model of housing prices is estimated with data collected from 3358 single-family home transactions. The results provide evidence for an optimal marketing period and indicate that a liquidity premium is priced in single-family home sales. Consistent with the hypothesis derived from economic search models, the model shows higher selling prices for houses having longer expected marketing periods. The model also shows a price premium for houses that sell faster than expectations. This effect supports the concept that liquidity is a value-enhancing characteristic.  相似文献

RONALD MA  ROGER HOPKINS 《Abacus》1992,28(1):113-115
Grinyer and Russell's (G&R, 1992) contention that Ma and Hopkins (1988) have imposed the mutually exclusive rules of the valuation-based paradigm on the matching-based paradigm that underlies accounting practice is overly defensive and misguided. Our 1988 paper was an attempt to throw light on why there was so little agreement on the rules governing the treatment of goodwill. G&R's comment does not change our view that the only answer to the 'puzzle' lies in the lack of a full understanding of the nature of goodwill.  相似文献
