Technologies of model‐based rationality are the core technologies of strategic management, having largely replaced earlier technologies that placed greater reliance on traditional practice or on communication either with the stars or with the gods. The technologies used by organizations in their pursuit of intelligence can be imagined to change over time as a result of responding to the successes and failures associated with the technologies. Although technologies of rationality seem clearly to be effective instruments of exploitation in relatively simple situations and to derive their adaptive advantage from those capabilities, their ventures in more complex explorations seem often to lead to huge mistakes and thus unlikely to be sustained by adaptive processes. Whether their survival as instruments of exploratory novelty in complex situations is desirable is a difficult question to answer, but it seems likely that any such survival may require hitchhiking on their successes in simpler worlds. Survival may also be served by the heroism of fools and the blindness of true believers. Their imperviousness to feedback is both the despair of adaptive intelligence and, conceivably, its salvation.

This paper looks at the policy debate surrounding private pensions and retirement patterns in the UK. Recent increases in longevity have led not only to increased pressures in public pensions but also to corresponding increases in the importance of private pensions in the UK and changes in the way in which they are structured. We consider the economic implications of these changes, and in particular the increased importance of defined contribution plans. In addition, we discuss the prospects for future trends in retirement ages.  相似文献

We analyze insurance holding company (IHC) issuance of trust‐preferred securities (TPS) from 1994 to 2013. We find that larger and more financially levered IHCs issued TPS in 1996 and 1997, as well as those that obtained financial strength ratings from A.M. Best. Abnormal stock price returns are positively related to financial distress costs, growth opportunities, and tax burden, but negatively related to size. Consistent with the pecking order theory, intent to use TPS proceeds to retire debt is positively related to abnormal stock returns, whereas intent to use proceeds to retire preferred equity is negatively related to abnormal stock returns.  相似文献

Growing technological complexity continues to drive firms to interact with the external innovation environment to achieve firm success. However, industries' complexities and the business model concept's underlying ontology have limited research on modeling the key factors that enable this interface. In this study, results of an empirical analysis of a unique dataset of 102 biopharmaceutical companies broadly support the EC‐LQO five‐factor framework as a useful tool to guide business model innovation for highly knowledge‐intensive environments.  相似文献

Multinational enterprises often employ their domestic accounting and control systems in their foreign affiliates. The literature suggests that, due in part to different operating environments around the world, this practice may impair the usefulness of information available to foreign managers, as their information needs differ from those of domestic managers. This study empirically examined information relevance for areas of manager responsibility in different countries and attempted to determine the environmental variables associated with information relevance. The results showed that formal accounting reports are considered more helpful in some countries, while informal discussion as a form of information is considered more helpful in others. However, the relationship between the business environment and information relevance was small, although significant, across many types of information.  相似文献

An estimated 12.6% of primary mortgage loans were simultaneously originated with a second loan from 2004 until 2008, although relatively little is known about how the presence of such subordinate loans affects the default decisions of borrowers. We use a novel data series of loan servicing records from 2002 until 2010 to identify such borrowers and find evidence that the default behavior of these borrowers significantly differs from borrowers without second loans. Estimating a discrete‐time proportional odds hazard model, we find borrowers with a second loan were 62.7% more likely to default each month on their primary loan when conditioning alone on the attributes of the primary loan. However, borrowers of second loans were 58.3% less likely to default on their primary loan as compared to single‐loan borrowers with equivalent current combined attributes (i.e., loan‐to‐value, balance and interest rate). We hypothesize and provide empirical evidence that this occurs because borrowers with second loans have the option to sequentially default on each loan since subordinate lenders will not pursue foreclosure if borrowers have insufficient equity. Lenders of defaulted subordinate debt may revisit their decision to foreclose in the future after housing markets start to recover, thus prompting a new round of foreclosures.  相似文献

The leaf tobacco marketplace is highly organized. Prior to 1940, the few large tobacco companies controlled that organization explicitly. The question is whether this organization set oligopsonistic leaf prices or minimized production and transaction costs. A model of joint oligopsonyoligopoly shows that pricing of cigarettes and leaf tobacco was unified: oligopolistic cigarette pricing was sufficient to curtail both cigarette production and leaf purchases. The companies could just bid in the market for the leaf necessary for that cigarette production rate.Prima facie, the organization was not for oligopsony coordination. The implied econometric model of pricing fits observed behavior well.Malcolm Boyd, Dennis Carlton, John Garen, Stephen Karlson, Li Way Lee, An-loh Lin, Robert Miller, Stephen Spurr and the referee have given me thoughtful, perceptive and useful comments. I am pleased to acknowledge their involvement without implicating them in whatever errors remain.  相似文献

In 2012, several large firms began purchasing single‐family homes, creating large portfolios of rental property, and securitizing these investments in capital markets. We present the first systematic evidence on this new investor activity in order to shed light on the factors that have supported its emergence. Three key factors were the ample supply of property for sale, tight mortgage financing and a decrease in acquisition and managerial costs brought about by technological advances. In addition, we show that buy‐to‐rent investors appear to have supported house prices in the neighborhoods where they concentrated.  相似文献
