The dean of Columbia Business School is joined by the deans of Stanford, Harvard, and Wharton in discussing the challenges and opportunities facing today's graduate business schools. Most business schools aim to provide students with a certain body of knowledge—in disciplines such as marketing, finance, and accounting—as well as some general management and leadership training and skills. The biggest challenge to this model of business education is now coming from the high cost of the traditional two‐year MBA program and the threat of disruption by “online” alternatives. But the consensus of the four deans is that the combination of training and experience provided by today's top business schools will enable them to withstand the threat from online alternatives. And thus for the leaders of these top schools, one of the main challenges in designing and maintaining a successful business school program is to find the right mix of theory and practice, classroom and “experiential” learning. To the extent the schools succeed in achieving and maintaining this balance, they should continue to produce graduates who are sought by employers that include not only companies large and small, but non‐profits and, at some points in their careers, even the public sector. What's more, the deans all sense the growing demand for business to play a larger role in addressing social problems that have traditionally been seen as the responsibility of government and non‐profits. And one implication of this demand is that business schools, besides producing talent that finds its way to the public as well as private sectors, should prepare to play a greater role in the public debate over solutions to social challenges, such as protecting the environment while at the same time trying to stimulate enough economic growth to limit rising inequality. 相似文献

This essay uses the case of Zanzibar in its complicated relationship with the United Republic of Tanzania (of which it is a part) as a lens on debates in political geography on empirical and conceptual approaches to critical geopolitics. We test the veracity of a multi-faceted critical geopolitics in the contemporary public contestation of Zanzibar's place in the United Republic from 2008–2012. We analyze Tanzanian media, the speech acts of Tanzanian leaders, and the key events and processes related to what is termed the ‘Zanzibar problem’ during the selected years, to make two points about a critical geopolitics approach: to strengthen critical geopolitics by broadening the analysis of language to engage political acts and languages beyond the Global North; and taking ‘subaltern geopolitics’ more seriously via engagement with critical geopolitical voices on discourses, events and processes from the Global South. 相似文献

Fixed transactions costs that prohibit exchange engender bias in supply analysis due to censoring of the sample observations. The associated bias in conventional regression procedures applied to censored data and the construction of robust methods for mitigating bias have been preoccupations of applied economists since Tobin [Econometrica 26 (1958) 24]. This literature assumes that the true point of censoring in the data is zero and, when this is not the case, imparts a bias to parameter estimates of the censored regression model. We conjecture that this bias can be significant; affirm this from experiments; and suggest techniques for mitigating this bias using Bayesian procedures. The bias-mitigating procedures are based on modifications of the key step that facilitates Bayesian estimation of the censored regression model; are easy to implement; work well in both small and large samples; and lead to significantly improved inference in the censored regression model. These findings are important in light of the widespread use of the zero-censored Tobit regression and we investigate their consequences using data on milk-market participation in the Ethiopian highlands. 相似文献

Some small-holders are able to generate reliable and substantial income flows through small-scale dairy production for the local market; for others, a set of unique transaction costs hinders participation. Cooperative selling institutions are potential catalysts for mitigating these costs, stimulating entry into the market, and promoting growth in rural communities. Trends in cooperative organization in east-African dairy are evaluated. Empirical work focuses on alternative techniques for effecting participation among a representative sample of peri-urban milk producers in the Ethiopian highlands. The variables considered are a modern production practice (cross-bred cow use), a traditional production practice (indigenous-cow use), three intellectual-capital-forming variables (experience, education, and extension), and the provision of infrastructure (as measured by time to transport milk to market). A Tobit analysis of marketable surplus generates precise estimates of non-participants' 'distances' to market and their reservation levels of the covariates — measures of the inputs necessary to sustain and enhance the market. Policy implications focus on the availability of cross-bred stock and the level of market infrastructure, both of which have marked effects on participation, the velocity of transactions in the local community and, inevitably, the social returns to agroindustrialization. 相似文献
