We analyze whether firms that receive venture capital (VC) at a later date face more financial constraints than a one-by-one matched sample of firms that did not receive VC funding (control group). The aim is to check whether their financial flexibility explains why they decide to seek external equity funding. In contrast with other papers, which focus on the sensitivity of investments to cash flow, we study this issue by applying a dynamic model to analyze the speed of adjustment to their target debt levels prior to receiving the first VC investment. We analyze a representative sample of 237 Spanish unlisted firms that received VC between 1995 and 2007 and its corresponding control group. We find that firms that receive VC funding show a significantly lower speed of adjustment than their matched peers before the initial VC round. It seems that the former are more concerned about funding the required investments than about adjusting the firm's debt ratio to a target level. Our results confirm the role of VC in filling the equity gap in constrained unlisted firms. From a capital structure perspective, VC may become a tool for these companies to balance their capital structure in a growth process.  相似文献

Social Vulnerability Index (SoVI) was applied to Greater Lisbon (Portugal). Based on the concepts used for the SoVI assessments in the US, 46 variables representing social vulnerability of the 149 civil parishes of Greater Lisbon were chosen. Thirty-eight variables were selected after application of correlation tests. They were standardized, and a Principal Component Analysis and a Varimax rotation were applied to them. Seven factors were extracted using the Kaiser criterion, which explain 79.5% of the variance, and the SoVI scores were then mapped using a standard deviation classification. Twelve of the 149 civil parishes of Greater Lisbon have a very high social vulnerability and 24 of them have a high social vulnerability. The map of SoVI was then integrated with susceptibility maps of earthquakes, floods, flash floods, landslides, tsunami, and coastal erosion, thus delineating risk zones. Twenty-two civil parishes of Greater Lisbon have a very high risk; among them, 17 belong to Lisbon Municipality, four belong to Loures Municipality, and one belongs to Vila Franca de Xira Municipality. Finally, exposed population was considered and combined with risk zones map in order to assess the number of people being potentially exposed to risk and their location.  相似文献

This study provides insight into the impact of industrial districts on the international activities of firms, in the particular context of one traditional manufacturing industry: the Spanish home-textile industry. Using a sample of 128 manufacturing firms, the paper shows how location influences the timing and levels of exports and imports. Moreover, our results demonstrate how these influences have been diluted in recent years as the home-textile industry becomes more involved in the global arena. Our findings challenge some key arguments exploring the advantages of the district in the international activities of firms; in particular, first, in questioning the capacity of the district to prevent international sourcing, and second, its vulnerability to the threats created by the growing integration of the world economy.  相似文献

This study looks at how a marketing organization changed its strategic orientation in response to environmental factors, and at the influence of retentions on the change effort. Retentions are defined , here as the concepts and mental models used by marketing managers when trying to respond to environmental changes. The influence of retentions on strategic orientation and factors affecting how retentions change are studied in the context of how a bank trust department responded to the deregulation of the financial services industry between 1982 and 1984. The dominant retentions held by managers both before and after deregulation are presented, and the events that contributed to the change of the retentions are examined. The results suggest that retentions prior to deregulation focused on external sources of influence and were associated with a defender strategic orientation. Retentions after deregulation, once the organization's strategic orientation stabilized, focused on critical resources and competitors and were associated with an analyser orientation. The adoption of the new retentions lagged deregulation by several years, and the transition did not match the steps prescribed by the marketing and strategic management literature. Instead, the transition took place through an iterative sequence of behaviours and evaluations more characteristic of the organizing model (Weick 1979). Managers changed their retentions incrementally by enacting small changes, evaluating the outcomes of their behaviour, and letting the outcomes redefine their retentions.  相似文献

ABSTRACT

Portugal and Spain have reformed their national standards to adapt them to the International Public Sector Accounting Standards (IPSAS). This paper explains the process of implementing the IPSAS for consolidated reporting in the two countries and the advantages and disadvantages which have emerged. The results highlight the role of the IPSAS in improving the quality and use of consolidated financial statements (CFS) and will be of interest to other countries that are intending to implement the IPSAS.  相似文献

Testing Gibrat’s Law for Small, Young and Innovating Firms   总被引:1,自引:0,他引:1  
This article analyses whether small, young, and innovating firms have experienced a greater employment growth than other Spanish firms over the period 1990–2000. The study draws upon a sample of 1272 manufacturing firms in which only 967 of the firms survived for the entire ten year period. The analyses test Gibrat’s law, both by least squares and by utilizing the procedure proposed by Heckman in which a probit survival equation is first estimated to correct for sample selection bias. Two estimators correcting for selection bias are utilized: one that incorporates the inverse Mill’s ratio and the other that employs maximum likelihood methods. All the results reject Gibrat’s law and support the proposition that small firms have grown larger. Additionally, the results show that old firms grow less than young ones, and innovating activity – both process and product – is a strong positive factor in the firm’s survival and its employment growth.  相似文献
