The authors model the channels through which public expenditure on infrastructure influences firm value and shapes its investment decisions via both adjustment costs and marginal profitability of capital. The authors test these hypotheses using a large panel of Italian firms. Empirical results show that infrastructure interacts with revenues and costs in shaping firm??s capital profitability and influences its adjustment costs. Finally, the authors find that infrastructure expenditure contributes to the reduction of the economic gap between the North and the South of Italy. These effects vary across regions and sectors.  相似文献

In this paper, we provide a generalization of the standard models of the diffusion of a new product. Consumers are heterogeneous and risk averse, and the firm is uncertain about the demand curve: both learn from past observations. The attitude towards risk has important effects with regard to the diffusion pattern. In our model, downward-biased signals to consumers can prevent the success of the product, even if its objective quality is high: a “lock-in” result. We show, in addition, that the standard logistic pattern can be derived from the model. Finally, we discuss the steady states of the learning dynamics, with regard to the multiplicity and the local stability of equilibria, and to their welfare properties.  相似文献

The aim of this article is to contribute to understanding the changing role of government in promoting corporate social responsibility (CSR). Over the last decade, governments have joined other stakeholders in assuming a relevant role as drivers of CSR, working together with intergovernmental organizations and recognizing that public policies are key in encouraging a greater sense of CSR. This paper focuses on the analysis of the new strategies adopted by governments in order to promote, and encourage businesses to adopt, CSR values and strategies. The research is based on the analysis of an explanatory framework, related to the development of a relational analytical framework, which tries to analyze the vision, values, strategies and roles adopted by governments, and the integration of new partnerships that governments establish in the CSR area with the private sector and social organizations. The research compares CSR initiatives and public policies in three European countries: Italy, Norway and the United Kingdom, and focuses on governmental drivers and responses. The preliminary results demonstrate that governments are incorporating a common statement and discourse on CSR, working in partnership with the private and social sectors. For governments, CSR implies the need to manage a complex set of relationships in order to develop a win–win situation between business and social organizations. However, the research also focuses on the differences between the three governments when applying CSR public policies. These divergences are based on the previous cultural and political framework, such as the welfare state typology, the organizational structures and the business and social and cultural background in each country.  相似文献

This paper analyzes the empirical performance of two alternative ways in which multi-factor models with time-varying risk exposures and premia may be estimated. The first method echoes the seminal two-pass approach introduced by Fama and MacBeth (1973). The second approach is based on a Bayesian latent mixture model with breaks in risk exposures and idiosyncratic volatility. Our application to monthly, 1980–2010 U.S. data on stock, bond, and publicly traded real estate returns shows that the classical, two-stage approach that relies on a nonparametric, rolling window estimation of time-varying betas yields results that are unreasonable. There is evidence that most portfolios of stocks, bonds, and REITs have been grossly over-priced. On the contrary, the Bayesian approach yields sensible results and a few factor risk premia are precisely estimated with a plausible sign. Predictive log-likelihood scores indicate that discrete breaks in both risk exposures and variances are required to fit the data.  相似文献

Since the mid‐2000s standard price‐competitiveness indicators for euro‐area countries have recently provided conflicting signals, particularly in Italy. The manufacturing unit labor cost (ULCM)‐based indicator reports a major competitiveness loss in Italy. Owing to the internationalization of production processes and to the fading representativeness of labor on overall costs we argue that price‐based measures are more appropriate than those based on ULCMs to assess external competitiveness and play a more important role in explaining export growth. Measuring non‐price competitiveness and considering global value chains are also crucial to correctly identify the determinants of trade flows in the four largest euro‐area countries.  相似文献

The labour productivity impact of demand and innovation is investigated in this paper combining insights from the Kaldorian and Schumpeterian traditions. After a review of studies in such traditions, a general model is proposed for explaining productivity growth in European manufacturing and service industries in the late 1990s, followed by two distinct specifications for the industries oriented toward product innovation, and for those where process innovation dominates. The empirical analysis is based on the match of the SIEPI‐CIS2 database developed at the University of Urbino and Eurostat Input–Output Tables at the industry level, for 22 manufacturing sectors and 10 services sectors. Six European countries are considered: Germany, France, Italy, the Netherlands, Portugal and the United Kingdom. The results show that productivity growth in European industries can be explained by a combination of technology factors and demand dynamics, confirming the complementarity of technology and demand effects. On the demand side, household consumption emerges as the most pervasive component of demand, able to stimulate greater efficiency in all manufacturing and service industries. Investment also has a role, focused however on the capital goods producing industries. On the technology side, the mechanisms of productivity growth are fundamentally different in the industries oriented towards product innovation and in those dominated by process innovation. This evidence supports the view that innovation in firms and industries can be associated to two contrasting strategies, searching either for technological competitiveness, through knowledge generation, product innovation and expansion of new markets, or aiming at greater cost competitiveness, through job reductions, labour saving investment, flexibility and restructuring.  相似文献

This paper analyses the Total Factor Productivity (TFP) heterogeneity of a sample of manufacturing firms operating in seven EU countries (Austria, France, Germany, Hungary, Italy, Spain and the UK). TFP data refer to 2008. The empirical setting is based on the multilevel modeling which provides two main results. Firstly, we show that TFP heterogeneity is largely due to firm-specific features (85% of TFP variability in the empty model). Interestingly, we find that some key-drivers of firm performance (size, family management, group membership, innovations and human capital) are significantly related to TFP, but do not, on the whole, absorb much of firm TFP variance, implying that differences in productivity are due to notable yet unobservable firm characteristics. Secondly, as far the role of localization is concerned, we demonstrate that the country effect is more influential than region effect in explaining individual productivity. Net of the country effect, the localization in different European regions explains about 5% of TFP firm heterogeneity. When considering the case of three individual countries, France, Italy and Spain, location in different regions explains 5.3% of TFP heterogeneity in Italy, while this proportion is lower (3.6%) in France and higher (9.9%) in Spain.  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

La capacità di fare previsioni sul mercato monetario è un punto cruciale nella gestione ottima di tesoreria di una banca, anche in virtú della possibilità di mobilizzare parte della riserva obbligatoria presso la Banca d’Italia. In questo studio viene mostrato come l’uso congiuuto di tecniche di previsione per i tassi a breve e la costruzione di un modello decisionale per la gestione della liquidità, basato sulle previsioni, permettano Alla banca di attnare una politica piu attiva con risultati globalmente positivi, in termini di interessi percepiti. A tal tine viene proposta una classe di previsori detti caolici e impostato un problema di decisione dinamica per la gestione ottima della riserva obbligatoria. Infine, si mostra un’applicazione di tale strategia sui tassiOvernight.  相似文献
