The aim of this study is to analyze the scale and cost inefficiencies in operation for the Swiss regional bus companies. For this purpose,we have considered estimation of a stochastic and a deterministic frontier cost model for a sample of 93 bus companies in 1989. The estimates of inefficiency from the frontier models are compared and discussed within the political and regulatory setting within which the Swiss regional bus companies operate. The empirical results indicate that regulation does not seem to influence the cost efficiency significantly. Only the tariff subsidies have a negative influence on efficiency. This is an interesting result because in the current transport policy debate, the abolition of this kind of subsidy has been raised. 相似文献

Firm size and the adoption of flexible automation 总被引:1,自引:0,他引:1
Data on the diffusion of flexible automation systems in the Italian metalworking industry are used to point out the role of size for the adoption of complex, systemic innovations. Plant and firm sizes turn out to be positively correlated to adoption rates. Moreover, adoption is more likely, ceteris paribus, in plants which are part of large industrial groups. This pattern applies in general, and is particularly remarkable for more advanced solutions. In this light, guidelines for industrial policies that focus on financial support, the diffusion of industrial standards, and the correction of asymmetries in the availability of know-how and skills are proposed.Financial support for this paper was provided by the Ministero della Pubblica Istruzione (MPI 40% research funds). Grants from the Fondazione Mauro and the CNR research project Tecnologie Meccaniche are also acknowledged. The research took advantage of the FLAUTO database, set up at the Laboratorio di Economia dei Processi di Automazione, MIP-Politecnico di Milano. 相似文献

This paper systematically investigates the sources of differential out-of-sample predictive accuracy of heuristic frameworks based on internet search frequencies and a large set of econometric models. The volume of internet searches helps gauge the degree of investors’ time-varying interest in specific assets. We use a wide range of state-of-the-art models, both of linear and nonlinear type (regime-switching predictive regressions, threshold autoregressive, smooth transition autoregressive), extended to capture conditional heteroskedasticity through GARCH models. The predictor variables investigated are those typical of the literature featuring a range of macroeconomic and market leading indicators. Our out-of-sample forecasting exercises are conducted with reference to US, UK, French and German data, both stocks and bonds, and for 1- and 12-months-ahead horizons. We employ several forecast performance metrics and predictive accuracy tests. Internet-search-based models are found to perform better than the average of all of the alternative models. For several country-asset-horizon combinations, particularly for UK bond returns, our heuristic models compare favourably with sophisticated econometric methods. The heuristic models are also shown to perform well in forecasting realized volatility. The baseline results are supported by several extensions and robustness checks, such as using alternative search keywords, controlling for Fama–French and Cochrane–Piazzesi factors, and implementing heuristic-based trading strategies. 相似文献

This paper focuses on social and environmental reporting (SER) and investigates, through prolonged fieldwork with an Italian multinational company, the dynamics through which SER, from its first introduction, has modified and developed to become institutionalized. The empirical data has been interpreted through the lens of institutional theories to provide a narrative of a three-step process which has brought about the institutionalization of SER, namely: (i) the construction of a common meaning system around the concept of social and environmental responsibility; (ii) practicalisation involving the emergence of rules and routines; and (iii) reinforcement through the implementation of intra-organizational managerial procedures and structures. The paper highlights that SER, as a result of a recursive and progressive process, has become an established and taken for granted actuality within the case study organization. 相似文献

Welfare gains to long-horizon investors may derive from time diversification that exploits nonzero intertemporal return correlations associated with predictable returns. Real estate may thus become more desirable if its returns are negatively serially correlated. While it could be important for long-horizon investors, time diversification has been mostly investigated in asset menus without real estate and focusing on in-sample experiments. This article evaluates, ex post, the out-of-sample gains from diversification when equity real estate investment trusts (REITs) belong to the investment opportunity set. We find that diversification into REITs increases both the Sharpe ratio and the certainty equivalent of wealth for all investment horizons and for both classical and Bayesian (who account for parameter uncertainty) investors. The increases in Sharpe ratios are often statistically significant. However, the out-of-sample average Sharpe ratio and realized expected utility of long-horizon portfolios are frequently lower than that of a one-period portfolio, which casts doubt on the value of time diversification. 相似文献

In this paper we focus on the determinants of internationalization and, in particular, on the specific role played by the agglomeration of small and medium sized enterprises (SMEs) through their proximity to a large firm. We study the characteristics of the internationalization process in a representative sample of 786 firms in the Italian automotive supply chain. After building an Internationalization Strategy Index (ISI), we perform a multinomial logit econometric analysis. The main findings of the empirical analysis are: (a) Italian automotive supplier firms mainly go in the foreign markets through export, i.e. the simplest internationalization mode; (b) as predicted in the literature, individual firm characteristics play a significant role in the probability of internationalization; (c) firms located in the province of Turin, where the dominant car assembler (Fiat) in Italy has its headquarters, or more generally, in large automotive industry districts, enjoy a clear localization advantage; (d) interestingly, we also find that internationalization is negatively correlated with the share of Fiat in suppliers’ sales, and that suppliers located in a district and less dependent on Fiat are also those adopting the most advanced internationalization strategies. 相似文献

Strategic market interaction is here modelled as a two‐stage game in which potential entrants choose capacities and next active firms compete in prices. Due to capital indivisibility, the capacity choice is made from a finite grid and there are economies of scale. In the simplest version of the model with a single production technique, the equilibrium turns out to depend on the ratio between the level of total output at the long‐run competitive equilibrium and the firm's minimum efficient scale: if that ratio is sufficiently large (the market is sufficiently ‘large’), then the competitive price emerges at a subgame‐perfect equilibrium of the capacity and price game; if not, then the firms randomize in prices on the equilibrium path. The role of the market size for the competitive outcome is shown to be even more important if there are several available production techniques. 相似文献

Venture Capital Investments in Europe and Portfolio Firms' Economic Performance: Independent Versus Corporate Investors 下载免费PDF全文
Using a new European Commission‐sponsored longitudinal dataset—the VICO dataset—we assess the impact of independent (IVC) and corporate venture capital (CVC) investments on the economic performance of European high‐tech entrepreneurial firms during the period 1992–2010. After controlling for potential sources of endogeneity and selection bias, our results indicate that both IVC and CVC investments boost portfolio firms' economic performance. These effects are mostly due to an increase in real sales value. Moreover, the dynamics of the impact of VC investments on firms’ overall economic performance and its components—real sales value, real fixed assets, and real labor costs—differs depending on the type of investor. Finally, we do not detect any impact related to the syndication of investments by both IVC and CVC investors. 相似文献
