In this paper, we seek to empirically assess which determinants of the capability and incentives of banks to screen and monitor firms are significant in explaining credit rationing to Italian SMEs. After testing for the presence of non‐random selection bias and the potential endogeneity of some determinants of interest, the probit model results we obtain suggest that the average banking size and the multiple banking relationship phenomenon are statistically significant factors affecting credit rationing, presumably through their impact on the aforementioned banks' capability and incentives. Other potential determinants of banks' incentives to monitor and screen, such as local banking competition and firm' capacity to collateralize, are never significant. However, when we split the sample according to the level of competition in credit markets, we find that the estimated marginal effects of all significant determinants of interest are larger in absolute value than those obtained when using the whole sample. 相似文献

In this paper we test two hypotheses concerning the presence of innovation in venture capital investments and the growth of innovative venture backed firms. To examine these hypotheses we considered sample of 37 Italian venture backed firms that went public on the Italian Stock Exchange between 1995 and 2004 and by a statistical matching procedure we picked 37 twin firms among the non‐venture backed IPOs for the same period. Our evidence shows that innovation is an important factor during the selection phase but once the investment is made, the company does not promote continued innovation and concentrates all efforts to improve other economic and managerial aspects. 相似文献

It is recognized that public health intervention targeted toward changing lifestyle behaviors to reduce overweight status is a considerable challenge. It is important that individuals recognize their overweight status as a health risk in order for an effective change in lifestyle behaviors to occur, and growing evidence suggests that actual weight and perception of weight status often do not match, especially among adolescents. In this article, we explore the extent to which exposure to heavier peers and parents affects misperception of their own weight status by adolescents. Using data from a nationally representative sample of adolescents, we estimated instrumental variable models with school‐level fixed effects to account for bidirectionality of peer influence and environmental confounders. Our results indicate that individuals who live in an environment that exposes them to overweight/obese parents and heavier peers tend to misperceive their weight status and think of themselves to be of lower weight than they actually are. Our analysis also revealed differential effects by gender and type of peers. 相似文献

The academic literature on the determination of risk-minimizing hedge ratios has apparently ignored the potential impact that the pricing strategies adopted by the grain elevators may have on the futures-cash price transmission, and therefore on the determination of the correct hedge ratio. This paper addresses this problem from a theoretical perspective, and then develops a model that is applied to the soybean market in Chatham, Ontario.
La littérature académique concernant la détermination des ratios de couverture à terme minimisant le risque a apparemment ignoré l'impact potential des stratégies des faiseurs de prix sur un marché sur la relation entre les prix spot et les prix à terme. II est possible que de ce fait ces stratégies influencent également la détermination du vrai ratio de couverture. Ce papier traite ce problème d'un point de vue théorique, puis vérifie ces résultats en les appliquant au cas du marché du soja à Chatham, Ontario. 相似文献

CSR in SMEs: do SMEs matter for the CSR agenda? 总被引:1,自引:0,他引:1
In this paper we argue that the collective grandness of small business is often underestimated in CSR research and policy-making. We emphasize the importance of understanding the contexts and the ways in which small- and medium-sized companies engage in CSR and how they differ from multinational companies. We suggest that it might be that researchers and practitioners are asking the wrong questions in their ambitions to prove 'the business case for CSR'. Perhaps we should rather focus on the 'how' and the 'with what impact' questions to understand better the SME engagement in CSR. 相似文献

Using a technique recently proposed by Gourieroux, Laffont and Monfort (1979) we prove that for a process mt asymptotically stationary in mean (ASM) the solution for the price level equation proposed in Fischer (1979) and in Blinder and Fischer (1979) is the unique ASM solution. 相似文献

Few studies have looked at the innovation process in the early stages of new business ventures in the context of business networks. Reporting on eight years of development of a new venture, we examine how the development of initial business relationships in an ever-changing business network affects technological innovation. We conclude that technological innovation is contingent on the development of business relationships that are a critical mechanism permitting a new venture not only to access but also to produce knowledge essential for innovating. For management this implies the need to strike a judicious balance between internal focus and closure to produce novel solutions and external focus and openness to experiment in business relationships. 相似文献

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales. 相似文献
