We study the impact of measures devoted to relieving financial constraints for the growth and survival of Italian innovative start-ups. Using balance sheet data on innovative start-ups and information on the use of the Italian Central Guarantee Fund for small and medium-sized enterprises, we evaluate whether access to the fund, relieving financial constraints, helps innovative start-ups survive and grow. We find innovative start-ups benefit significantly more than similar control firms. We shed light on the relevance of policies aimed at reducing financial constraints for the growth and survival of innovative start-ups, an issue receiving increasing attention at the European level.  相似文献

The economic literature has attributed part of the increase in government expenditure over the 20th century to female voting. This is puzzling, considering that the political science literature has documented that women tended to be more conservative than men over the first half of the 20th century. We argue that the current estimates of this relationship are afflicted by endogeneity bias. Using data for 46 countries and a novel set of instruments related to the diffusion of female suffrage across the globe, we find that, on average, the introduction of female suffrage did not increase either social expenditures or total government expenditure.  相似文献

Measuring research and development (R&D) performance has become a fundamental concern for R&D managers and executives in the last decades. As a result, the issue has been extensively debated in innovation and R&D management literature. The paper contributes to this growing body of knowledge, adopting a systemic and contextual perspective to look into the problem of measuring R&D performance. In particular, it explores the interplay between measurement objectives, performance dimensions and contextual factors in the design of a performance measurement system (PMS) for R&D activities. The paper relies on a multiple case study analysis that involved 15 Italian technology-intensive firms. The results indicate that firms measure R&D performance with different purposes, i.e. motivate researchers and engineers, monitor the progress of activities, evaluate the profitability of R&D projects, favour coordination and communication and stimulate organisational learning. These objectives are pursued in clusters, and the importance firms attach to each cluster is influenced by the context (type of R&D, industry belonging, size) in which measurement takes place. Furthermore, a firm's choice to measure R&D performance along a particular perspective (i.e. financial, customer, business processes or innovation and learning) is influenced by the classes of objectives (diagnostic, motivational or interactive) that are given higher priority. The implications of these results for R&D managers and scholars are discussed in the paper.  相似文献

We introduce block bootstrap techniques that are (first order) valid in recursive estimation frameworks. Thereafter, we present two examples where predictive accuracy tests are made operational using our new bootstrap procedures. In one application, we outline a consistent test for out‐of‐sample nonlinear Granger causality, and in the other we outline a test for selecting among multiple alternative forecasting models, all of which are possibly misspecified. In a Monte Carlo investigation, we compare the finite sample properties of our block bootstrap procedures with the parametric bootstrap due to Kilian (Journal of Applied Econometrics 14 (1999), 491–510), within the context of encompassing and predictive accuracy tests. In the empirical illustration, it is found that unemployment has nonlinear marginal predictive content for inflation.  相似文献

U.S. companies are now reportedly earning record‐high operating returns on capital while at the same time continuing to set new records both for corporate cash holdings and distributions to investors in the form of dividends and stock repurchases. But are most of these companies really maximizing value? And what role, if any, do these large distributions play in creating value? These are the two main questions that are addressed by a small group that includes two senior corporate executives and two representatives of well‐known activist investors. A number of panelists suggest that many companies, in misguided efforts to maximize returns on capital, have been using hurdle rates that are too high and so sacrificing value‐adding investment opportunities. As evidence for this claim, they cite evidence that, in recent years, the companies that have achieved the highest stock market returns appear to have made conscious decisions to reduce their returns on capital to pursue higher growth. Another increasingly common charge against U.S. companies is their tendency to pay out excessive capital to investors, especially in the form of stock repurchases at prices that turn out to be too high. But this last practice, however widespread, may not be as troubling as it has been made out to be. Although it involves a wealth transfer from existing to selling shareholders, overall investor value is lost only if such buybacks lead to corporate underinvestment. But, as a number of panelists (including the activist investors) point out, such payouts of capital have generally functioned as a demonstration of corporate managers' commitment to investing and operating with the optimal, or value‐maximizing, level of capital—neither too much nor too little.  相似文献

This paper gauges volatility transmission between stock markets by testing conditional independence of their volatility measures. In particular, we check whether the conditional density of the volatility changes if we further condition on the volatility of another market. We employ nonparametric methods to estimate the conditional densities and model-free realized measures of volatility, allowing for both microstructure noise and jumps. We establish the asymptotic normality of the test statistic as well as the first-order validity of the bootstrap analog. Finally, we uncover significant volatility spillovers between the stock markets in China, Japan, UK and US.  相似文献

The aim of this article is to investigate whether family control, family management and family ownership concentration affect the investment-cash flow sensitivity of small- and medium-sized enterprises (SMEs). By analysing a sample of Italian SMEs for the period 2004–2013, I find that family-owned businesses are significantly associated with higher investment-cash flow dependence. This relation, however, is found to be driven by two distinct factors: (i) the presence of a highly concentrated family ownership (ownership concentration channel) and (ii) the active involvement of the family in the business (family management channel).  相似文献
