This article discusses personal entrepreneurial competences (PECs) from a dynamic, changing perspective to demonstrate that the behavior of the entrepreneur before setting up a company is not the same as after years of experience. To that effect, 1,163 entrepreneurs and 27 CEOs answered a questionnaire based on the concept of PECs. Results suggest that there are differences between the two groups. The article is contextualized in Spain, where the Polytechnic University of Valencia has a service called the IDEAS Institute, dedicated to supporting entrepreneurs and to enhancing firm creation.  相似文献

The objective of this article is to conceptualize the value creation process in brand alliances using a dynamic approach, based upon the literature on strategic alliances and inter organizational relationships, to explain the importance of organizational components in brand alliances. The research question is to identify the key components which allow the creation and sustaining of value: context, actors, objectives, behaviors, resources, and governance mechanisms, internal and external conditions affecting the value creation process. Then the framework is applied in case studies of brand alliances in the food market. We show that the impact of these components depends on the nature of the organizations involved, on market conditions and on the manner resources and governance mechanisms are combined together.  相似文献

Many European governments still advocate a so-called ‘cultural exception’, intended to protect consumers and smaller bookshops, to keep their book markets isolated from competition. Other countries, with similar aims in mind, have chosen liberalization schemes instead. To reconcile these opposing views, this paper provides a theoretical framework to study the textbook market, depicting it as dominated by two simultaneous forces: horizontal differentiation among booksellers and a vertical relationship between publishers and bookshops. Using this model, we analyse the effects of alternative price schemes on the market structure and how potential benefits from price liberalization are influenced by the number (and size of) booksellers.  相似文献

This paper examines the impact of financial constraints on innovation for established firms. We make use of a direct measure of the existence of financial constraints obtained thanks to a specific survey addressed to French established firms. This is a distinctive feature of this paper as most of previous studies had to rely on proxies (like the cash-flow sensitivity), which may be subject to interpretation problems. The probability to have innovative activities and the probability to face financial constraints are simultaneously estimated by a recursive bivariate probit model. Accounting for the endogeneity of the financial constraint variable, we find that financial constraints significantly reduce the likelihood that firms have innovative activities. The probability to encounter financial constraints is explained by firms’ ex ante financing structure and economic performances.  相似文献

Why did the conventional leverage indicators not pick up any meaningful signal of the mounting systemic risk before the subprime crisis? They remained almost unchanged in recent decades, whereas the banking landscape underwent a tremendous metamorphosis. Market-oriented banking is characterized by a new type of systemic risk, a risk which essentially evolves off the radar screen, i.e., off-balance sheet (OBS) (Calmès and Théoret Journal of Banking and Finance 34 (7): 1719–1728, 2010, 2011). In this article, we argue that the standard leverage indicators are not fitted to capture this kind of new banking risk. We introduce a new empirical framework which enables us to exploit the cyclical properties of elasticity leverage measures, while at the same time controlling for the noisy information they usually deliver. In a nutshell, thanks to the Kalman filter, we are able to compute optimal levels of bank leverage. This methodology delivers cyclical, forward-looking measures signalling systemic risk bubbles years before their burst. By properly accounting for all activities, including market-oriented banking, these time-varying leverage measures tend to systemically capture regulatory capital arbitrage and the OBS risk it entails.  相似文献

We show that credit market imperfections substantially increase the government-spending multiplier when the economy enters a liquidity trap. This finding is explained by the tight association between capital goods and firms? collateral, a relationship that we highlight as the capital-accumulation channel. During a liquidity trap, a government spending expansion reduces the real interest rate, leading to a period of cheap credit. Entrepreneurs use this time to accumulate capital, which persistently improves their balance sheets and reduces their future costs of credit. A public spending expansion can thus encourage private investment, yielding consequently a large spending multiplier. This effect is further reinforced by Fisher?s debt-deflation channel.  相似文献

Amartya Sen's enlarged conception of freedom has augmented the scope of economic analysis but it also has had the surprising effect of being more supportive of the free market than conventional welfare economics. It is argued here that a comparison of Sen's position with that of the American institutionalist, J R Commons, highlights some problems with Sen's approach and points to possible ways in which they might be addressed.  相似文献

This paper reconsiders the importance of the sovereign state in contemporary geopolitics. The role of the state in an era of globalisation and devolution is a concern that has gained considerable attention in recent geographical scholarship. What has received less attention is how the state has historically functioned as a device that conflated the linked concerns of sovereignty and territoriality. The authors argue that there exist a number of “sovereignty paradoxes” that inhibit the interdisciplinary analysis of the interrelations between sovereignty, territoriality, and state power. Thus, reconsidering sovereignty and territoriality informs both how the state emerged as an important unit of geographical analysis historically, and why the state has become such a problematic concept in contemporary geopolitics. This work has implications for understanding popular struggles over civil liberties, foreign policy, and justice for indigenous peoples.  相似文献

This article explores the role of framing in mobilizing and transforming narrative resources. It draws on in‐depth studies of two different workplace unions within the same multinational company in Canada. We conducted interviews with managers and trade unionists at different levels over a number of years of observation. Each of these workplace unions mobilizes new repertoires of action to enhance its capacity to act. Yet they differ considerably in their capacity to renew their narrative resources. Whereas one of the workplace unions still relies on an exclusive and restrictive narrative, the other union has evolved towards a more encompassing and inclusive narrative. This article argues that strategic capabilities are a key variable in understanding the processes through which narrative resources change and are mobilized.  相似文献

The Carpathian Basin is one of the most vulnerable European regions in terms of potential climate change impacts on biodiversity. Its wide range of tourism activities make it uniquely suitable for assessing the effects of climate change on tourism. This research sought to create a Tourism Adaptation Portfolio (TAP) for the Szentendre micro-region in Hungary and to assemble an adaptation toolbox for current and future use by tourism organizations. The TAP contains practical, easy to implement solutions for key stakeholders in the sector by adaptation type (technology, management, behavior, education, policy). Surveys of local tourism suppliers showed that 70% said they were well informed, largely by the Internet, but 55% admitted to not knowing enough. The methodology outlined here is transferable and the process can be replicated elsewhere, supporting other regions in becoming climate-friendly tourism destinations, creating opportunities for uniquely positioning a region for consumers. The article provides a concise overview of tourism provider attitudes assessed through a questionnaire, shedding light on points of intervention, willingness to pay, main barriers and suitable adaptation instruments. The adaptive capacity of stakeholders is also discussed, which is indispensable for implementing successful practices in adaptation and maintaining the current level of environmental services.  相似文献
