Italy is an ideal candidate for testing the credit view of the transmission mechanism because of a bank-centred financial structure, a sizeable trade debt, and an economy titled towards small firms. An empirical analysis of trade credit and debt on averaged panel data shows that small firms act as financially constrained and cycle-sensitive, whereas large ones aim at smoothing sales, adopt an integrated management of inventories and receivables and have a higher trade debt to purchases elasticity. On balance, the net trade credit channel does not, as implied by the credit view, shield small firms from a monetary squeeze.  相似文献

International posting of workers and mobility of self‐employed service suppliers lie between outright migration and trade in goods: their regulation, for both distributional and market‐correcting purposes, is not as difficult to harmonise as that of labour markets, but personal mobility is more visible and socially intrusive than product market interactions. This paper analyses economic and legal tensions between national regulatory frameworks and international competition in these areas, in both the intra‐EU and global contexts, highlighting how interactions between the external and internal roles of the European Commission may foster efficient integration of markets and policies in this and other fields.  相似文献

The aim of this paper is to analyze the performance of alternative forecasting methods to predict the index of industrial production in Italy from 1 to 3 months ahead. We use twelve different models, from simple ARIMA to dynamic factor models exploiting the timely information of up to 110 short-term indicators, both qualitative and quantitative. This allows to assess the relevance for the forecasting practice of alternative combinations of types of data (real-time and latest available), estimation methods and periods. Out-of-sample predictive ability tests stress the relevance of more indicators in disaggregate models over sample periods covering a complete business cycle (about 7 years in Italy). Our findings downgrade the emphasis on both the estimation method and data revision issues. In line with the classical “average puzzle”, the use of simple averages of alternative forecasts often improves the predictive ability of their single components, mainly over short horizons. Finally, selected indicators and factor-based models always perform significantly better than ARIMA models, suggesting that the short-run indicator signal always dominates the noise component. On this regard, selected indicators models can further increase the amount of signal extracted to improve up to 30–40% the short-run predictive ability of factor-based models and to forecast-encompass them.  相似文献

We assess the employment impact of the Lisbon Strategy, examining long-run growth in total, female and old-age employment rates from 1994 to 2009. The Strategy had some impact, especially for old-age workers, but no improvement ensued from its mid-term reassessment.  相似文献

The paper presents the first results of research carried out by the authors in the research centre of an important Italian industrial group. The management of the centre is strongly interested in new methodological approaches to identify and to represent individual competences. To satisfy this specific need, the authors suggest a method based on the matrix of competences that is the set of relationships between capabilities and situations. The situations and the capabilities are identified by analysing the judgements that other subjects, internal or external to the organization, express on an individual's behaviour.
A sample of fifteen individuals has been investigated in order to identify their individual competences and the most significant situations within the centre. For each individual a network of subjects, the supervisor and some clients and collaborators, has been considered. On the basis of the results, the implications for management are discussed, with particular regard to the design of new procedures for personnel evaluation.  相似文献

This paper studies the effect of intention-based reciprocity preferences on the free-riding problem arising in partnerships. Our results suggest a tendency of efficient partnerships to consist of members whose sensitivity to reciprocity is – individually or jointly – sufficiently high. Sufficient conditions for the implementation of the efficient strategy profile require a reciprocity-based sharing rule so that each partner gets a fraction of the output, which is a percentage of his own sensitivity to reciprocity with respect to the overall sensitivity in the team. Finally, we introduce the concept of psychological strong Nash equilibrium and show that it allows for the unique and collusion-proof implementation of the efficient strategy profile.  相似文献

Testing for unit roots in time series models with non-stationary volatility   总被引:2,自引:0,他引:2  
Many of the key macro-economic and financial variables in developed economies are characterized by permanent volatility shifts. It is known that conventional unit root tests are potentially unreliable in the presence of such behaviour, depending on a particular function (the variance profile) of the underlying volatility process. Somewhat surprisingly then, very little work has been undertaken to develop unit root tests which are robust to the presence of permanent volatility shifts. In this paper we fill this gap in the literature by proposing tests which are valid in the presence of a quite general class of permanent variance changes which includes single and multiple (abrupt and smooth-transition) volatility change processes as special cases. Our solution uses numerical methods to simulate the asymptotic null distribution of the statistics based on a consistent estimate of the variance profile which we also develop. The practitioner is not required to specify a parametric model for volatility. An empirical illustration using producer price inflation series from the Stock–Watson database is reported.  相似文献

This paper contributes to the analysis of the persistence of innovation activities, as measured by total factor productivity (TFP), and explores its internal and external determinants stressing its path-dependent characteristics. The external conditions, namely the quality of local knowledge pools and the strength of the Schumpeterian rivalry, along with the internal conditions (the actual levels of dynamic capabilities, as proxied by wage levels and firm size) exert a specific and localised effect upon the persistent introduction of innovations. A multiple transition probability matrixes (MTPMs) approach has been implemented to capture the contingent effects of external factors on long-term innovation persistence. The empirical analysis of the dynamics of firm-level TFP for a sample of approximately 7000 Italian manufacturing companies observed during the years 1996–2005 is based on both the comparison of different transition probability matrixes and on dynamic discrete choice panel data models. The evidence provided by the test of MTPMs in sub-periods suggests that innovation persistence is path-dependent, as opposed to past-dependent.  相似文献

This paper provides new evidence on the quantification of economic losses and/or gains from skilled human capital mobility in terms of GDP and productivity in several EU countries during and after the Great Recession. We construct two novel indicators to quantify and compare the economic effects of human capital mobility across EU countries in 2008, 2012, and 2016. Through hierarchical clustering, we created groups of countries to perform a non-parametric MANOVA. The results suggest the existence of three groups of countries aggregated by similar economic and mobility patterns. The differences between these groups are significant and allow us to delineate the countries’ gains and losses.
