On apprend plus par la conversation des Doctes, que par la lecture de leurs livres Les épistres de Seneque Translation by François de Malherbe, Paris, Anthoine de Sommaville, 1639, p. 21 Small and medium-sized enterprises, because of their limited resources, use a variety of sources and are linked to different networks to obtain the information they need to develop their strategy and then to gradually organize their environment. Among other things, networks keep them up-to-date with changes in the economy and allow them to take advantage of opportunities to innovate, thus remaining ahead of their competitors. The networks – personal or business – with which these firms interact the most are usually geographically or sociologically close by, embedded in the environment, and are known as strong tie networks. They generally supply signals in a familiar language, based on habit as well a good reciprocal knowledge, which are easy to understand. In addition to this, however, the most dynamic firms also have contacts with weak tie networks, which are further removed from the usual behaviours of entrepreneurs and provide weak signals that, while difficult to grasp and decode, nevertheless offer new, pre-competitive information that can support major innovations. Very little empirical research has been done so far to test the probability of this theory. This paper reports on the results of a survey involving 147 SMEs, all in the land-based transportation equipment sector. It confirms the importance of weak tie networks as opposed to other types of networks, recognizing their complementary contribution to technological innovation. The organization's absorptive capacity is also found to be a significant intermediary factor in taking advantage of weak tie networks. 相似文献

This study explores the following novel research question: Do attributes relating to the resources and signals of lead entrepreneurs, particularly prior business ownership experience quality signals, reduce the probability that entrepreneurs will be chronic credit-rationed entrepreneurs in a developing economy context with resource deficiencies? Guided by insights from signalling, resource-based view of the firm and human capital theory, profiles of credit-rationed entrepreneurs (i.e. debt finance obtained but below the amount requested) are highlighted. The length of the debt finance gap was considered with regard to temporary (over one year), major (over two years) and chronic (over three years) finance gaps. We find support for our hypotheses relating to entrepreneurs whose firms are more innovative being more likely to be chronically credit-rationed, whilst firms with partners, entrepreneurs with longer prior business ownership experience and habitual entrepreneurs are less likely to be credit-rationed. The interaction with serial or portfolio entrepreneur reduces the chronic credit-rationing problem faced by innovative firms. A case for developing linkages between inexperienced novice entrepreneurs and habitual entrepreneurs, particularly successful portfolio entrepreneurs, is made. Notably, we suggest that building upon the experienced entrepreneurs who do exist may be particularly beneficial in resource deficit contexts such as Ghana 相似文献

Events that occur over a period of time can be described either as sequences of outcomes at discrete times or as functions of outcomes in an interval of time. This paper presents discounting models for events of the latter type. Conditions on preferences are shown to be satisfied if and only if the preferences are represented by a function that is an integral of a discounting function times a scale defined on outcomes at instants of time. 相似文献

In this commentary, we reflect on Thornton's (2013) extension to his original CA Magazine article on environmental accounting (Thornton, 1993) as well as the original contribution. Given our background in social and environmental disclosure research, we question Thornton's narrow focus on environmental accounting as it relates to the debits and credits of financial reporting, and we attempt to illustrate the problems that voluntary environmental disclosure creates with respect to reduced incentives for companies to improve environmental performance. We conclude by identifying our concerns with the future of environmental accounting given the recent ‘rediscovery’ of the topic by mainstream accounting researchers. 相似文献

Government‐protected banking systems tend to blow up, imposing huge losses on taxpayers. In a recent much‐publicized book, The Bankers' New Clothes, Anat Admati and Martin Hellwig propose to fix this problem by forcing banks to maintain 25% of their assets in the form of equity rather than debt. But this author argues, the book overstates the benefits and understates the costs of the proposed reform, while also failing to identify additional necessary reforms. Because bank equity is not true equity, and equity must be evaluated only in relation to risk, increasing required book equity ratios will not necessarily reduce the risk of bank failure significantly. Raising equity requirements is also socially costly because it reduces banks' willingness to lend. When banks need to raise their equity‐to‐asset ratios, they often choose to do so by cutting back on new loans, rather than paying the high costs of raising new equity. The reduction in loan supply that comes from raising equity ratios can be substantial, and is not just a one‐time cost. Balancing the costs and benefits of higher equity implies a much lower required equity ratio than the 25% posited in The Bankers' New Clothes. Finally, because equity ratios relative to risk should be the focus of prudential regulation, additional regulatory policy reforms that strengthen incentives for more effective risk management are needed in addition to higher capital ratios. 相似文献

A simultaneous equations framework is used to study the relationship between structure, conduct and performance in US manufacturing in the 1980s and 1990s. The paper expands on earlier structure-conduct-performance studies by using a lag structure to signify that structure, conduct and performance do not affect one another contemporaneously. Findings support some aspects of the traditional structure-conduct-performance model, but challenge others. First, the data suggest that industry structure does not depend on current industry performance. Second, little evidence is found that industry conduct, proxied by advertising, is affected by industry structure. Third, results show that industry performance does not depend on industry conduct, though it is sensitive to industry structure. The main findings are that (1) concentration does not depend on firm profitability, though profitability depends on concentration, (2) advertising follows a process that is independent of the factors considered here, and (3) advertising seems to have no effect on profitability. 相似文献

In this paper, the performance of the New Keynesian IS curve for the G7 countries is assessed. It is found that there is an IS puzzle for both the purely backward-looking as well as for the forward-looking IS curve. The real interest rate does not have a significantly negative effect on the output gap. Based on an extended specification of the IS curve, also including asset prices and monetary aggregates, a significantly negative interest rate effect on aggregate demand is found for all countries. This finding suggests that a richer specification of the IS curve in empirical work may be necessary in order to obtain an unbiased estimate of the effect of monetary policy on aggregate demand. 相似文献

This article develops a broad theme about treatment under ambiguity through study of a particular decision criterion. The broad theme is that a planner may want to cope with ambiguity by diversification, assigning observationally identical persons to different treatments. Study of the minimax‐regret (MR) criterion substantiates the theme. The article significantly extends my earlier analysis of one‐period planning with an individualistic treatment and a linear welfare function. I show that MR treatment allocations are fractional in a large class of planning problems with nonlinear welfare functions, interacting treatments, learning, and noncooperative aspects. 相似文献

Auctions with costly information acquisition 总被引:1,自引:0,他引:1
We characterize optimal selling mechanisms in auction environments where bidders must incur a cost to learn their valuations.
These mechanisms specify for each period, as a function of the bids in previous periods, which new potential buyers should
be asked to bid. In addition, these mechanisms must induce the bidders to acquire information about their valuations and to
reveal this information truthfully. Using a generalized Groves principle, we prove a very general “full extraction of the
surplus” result: the seller can obtain the same profit as if he had full control over the bidders’ acquisition of information
and could have observed directly their valuations once they are informed. We also present appealing implementations of the
optimal mechanism in special cases.

This article examines how the action logics associated with the stages of consciousness development of organizational leaders
can influence the meaning, which these leaders give to corporate greening and their capacity to consider the specific complexities,
values, and demands of environmental issues. The article explores how the seven principal action logics identified by Rooke
and Torbert (2005, Harvard Business Review
83(4), 66–76; Opportunist, Diplomat, Expert, Achiever, Individualist, Strategist and Alchemist) can affect environmental leadership.
An examination of the strengths and limitations of these action logics reveals the relevance of the so-called post-conventional
stages of consciousness to the recognition and effective management of complex environmental issues. Suggestions are also
made for promoting organizational contexts conducive to the development of a post-conventional environmental leadership. 相似文献
