The current hype about culture‐led local development models is causing an increasing interest in cultural policies in the broader context of urban policy. This is not necessarily a transitory situation bound to fade once the hype is over. Under certain conditions, there is room to believe that culture may indeed become a main development driver of urban systems. For this to happen, however, it is necessary to abandon simple mono‐causal developmental schemes (such as the ‘creative class’ model) and look for more articulated approaches. This calls in turn for a complex systems‐based conceptual framework that is at the same time rich enough to capture the complexity of the interdependences among policy and state variables, and manageable enough to be of practical use, not only for policy design professionals but also for local stakeholders who want to take part in collective decision‐making processes. Inclusiveness and collective decision making are almost unavoidable in the case of cultural planning strategies, as the social sustainability of culture‐based value creation processes crucially depends on boosting the level of access to cultural opportunities by local residents. In this article we present an approach that may be a tentative first step in this direction.  相似文献

Economic growth,Koestler cycles and the lock chamber effect   总被引:1,自引:0,他引:1  
This paper develops a suggestion contained in a 1940 novel by A. Koestler. A dynamic model is built to analyze the relationship among economic growth, complexity, “maturity” of the population, and propensity to contribute to the stock of a public good. Economic growth is represented as a process that exogenously generates technical innovations: these increase the division of labor and make the social structure increasingly complex. Information about the new structure can only be gathered at a cost, so that in general, knowledge of the “true” structure lags behind the changes of the structure itself. Economic growth then causes cycles in the individuals’ perception of their best interests. Accessibility to information influences the length and the amplitude of such cycles.  相似文献

Poor local information networks and weak social sanctions in urban settings make joint liability unable to guarantee high repayment rates to microlenders. Yet, microcredit programmes in Western Europe report good performance even if the majority of them require no collateral. We collected data from three Italian microcredit institutions which operate in urban areas, granting individual loans without collateral to single entrepreneurs and teams (associations and cooperatives). We found that teams repay with higher probability. On this basis we developed a microlending instrument which, like joint liability implemented in rural economies, mitigates informational problems but, unlike joint liability, fits the urban context in that it reproduces a cohesion among entrepreneurs based on profit‐maximizing behaviour and not on social capital.  相似文献

Forecasting represents a core project management process. Estimates at completion in terms of cost and schedule provide essential data and advice to the project team in order to lead and control the project and implement suitable corrective measures. In order to improve the forecasting process, a Bayesian model has been developed within the earned value management framework aiming to calculate a confidence interval for the estimates of both cost and schedule at the completion of the project. The model is based on the integration of data records and qualitative knowledge provided by experts. The model has been tested in an oil and gas project.  相似文献

This experimental study aims to clarify to what extent and in which direction investors react to CSR (Corporate Social Responsibility) initiatives meant to upgrade the ethical standards of firms beyond the minimal requirements of law. Subjects in the laboratory were invited to invest their endowment in a portfolio of financial assets. We provided information on the expected returns of each stock and on its inclusion in an ethical index, or exclusion from it. Our findings show that subjects’ behavior appears to be a function not only of their individual pay-offs but also of the information on the ethical standards of the firms issuing stocks. Most of them, however, did not show a fully irrational behavior as they consistently correlated the share of stocks with their expected returns. We may conclude that the sizeable reaction of our investors to the inclusion of a stock in the ethical index, or its exclusion from it, is the fruit of a deliberate choice.  相似文献

The paper concerns a study on the changes affecting leading cluster companies' supplier relationships. In particular, the paper aims at investigating under which conditions and how industrial cluster companies rely on local suppliers in the current context of international competitive pressure and easier access to international supply sources. The research methodology is qualitative and based on a long-term longitudinal research of three case studies of Italian industrial cluster companies that are leading firms in specific niches of the mechanical industry. Two main questions are debated: under which conditions have industrial cluster companies relied on local suppliers? What has been the evolution of relationships between industrial cluster companies and their local suppliers? The empirical analysis shows that local suppliers have been playing strategic roles in different ways in distinct historical phases, contributing actively in terms of knowledge and competence development, production flexibility, delivery performance and cost efficiency.  相似文献

Under the principle of the failing firm defence a merger that would be blocked due to its harmful effect on competition could be nevertheless allowed when (i) the acquired firm is actually failing, (ii) there is no less anticompetitive alternative offer of purchase, (iii) absent the merger, the assets to be acquired would exit the market. We focus on potential anticompetitive effects of a myopic application of the requirement (iii) by studying consequences of a horizontal merger on entry in a Cournot oligopoly with a failing firm. Entry is deterred if the merger is cleared and, when the industry is highly concentrated, consumer welfare is higher under a prohibition because long‐run gains due to augmented competition exceed short‐run losses due to shortage of output.  相似文献

We analyse voting on the devolution of the responsibilities for the provision of public goods to local governments in a federal country, with a bicameral national legislature. In our set-up, devolution means a constitutional fiscal reform which reduces federal public expenditure on a local public good, and simultaneously increases the transfers received by regions, via a tax-sharing mechanism. This allows the regions to provide a greater amount of a local public good which can compensate for the reduction of that provided upon a federal basis. We show under which conditions such a devolution reform is adopted or rejected.  相似文献

This paper shows that managers' personal beliefs and individual characteristics explain a large share of the substantial time-variation of derivative use beyond firm, industry, and market fundamentals. We construct a panel data set of foreign currency derivative holdings and currency exposures for U.S. non-financial firms. We use a novel approach to build a firm-specific foreign exchange return. We find that managers adjust derivatives notional amounts in response to past foreign exchange returns, as if they were forming views on future currency prices. We then construct an empirical measure of speculative behavior for each firm to investigate the profile of the speculator. Firms where the CEO holds an MBA degree, is younger, and has less previous working experience speculate more. These results are consistent with overconfident managers taking more risk.  相似文献

This paper reviews the evidence on financing technology-based small firms (TBSFs) in Europe. European TBSFs finance new investments by relying primarily on internal funds, due to capital market failures induced by asymmetric information. European venture capital has caught up with US venture capital, but this is mainly because of the growth in UK venture investments. It is unclear whether European venture capital has been able to certify the quality and enhance the growth of funded companies. Compared with the NASDAQ, there is little development of trading in high-tech stocks in Europe: the so-called New Markets established in the 1990s collapsed in the wake of the Internet bubble crash. Public venture capital and research and development (R&D) tax incentives seem to have positively affected high-tech firms.  相似文献
