We study how aggregate volatility is influenced by the propagation of idiosyncratic shocks across firms through the network of ownership relations. We use detailed data on cross-holdings as well as the relevant balance sheet information for almost the entire universe of Italian limited liability...

The Italian and European regulatory framework for patents would benefit from further improvements in order to foster dynamic competition between Italian firms. At the national level the exclusive allocation of the right to patent inventions to universities, rather than to researchers, would...

Direct and country-specific measures of technical progress are used in order to analyse the effects of technology shocks on output fluctuations in the G7. Technology shocks are measured as the unpredicted component in the dynamics of innovation, on the basis of patent statistics provided by the...

This paper evaluates the causal effect of issuing equities on the probability that a firm will engage in R&D activity. Equity is a preferable source of external finance for innovation than debt. It does not require collateral, does not exacerbate moral hazard problems connected with the...

In the last decade R&D expenditure in Italy has been lagging at a bare 1.2-1.3 per cent of GDP. Its private share is low by international standards and Italian firms take out only a small number of patents. External sources of innovation, however, are available to firms. This work aims at...

The paper describes the innovation strategies of a representative sample of Italian firms participating to the Bank of Italy�s yearly survey. The evidence covers the 2008-2010 period and highlights some stylized facts widely discussed in the economic literature. Results show that the...

We propose a theory-based approach to testing the presence of the 'home market effect' in a multi-country world. Our framework extends Krugman's (1980, Am. Econ. Rev. 70(5), 950-959) model, in which the appeal of a country as a production site depends on both the relative size of its domestic...

We develop a multi-country Dixit-Stiglitz trade model and analyze how industry location and welfare respond to changes in: (i) transport frictions (e.g., infrastructure, transportation technology); and (ii) non-transport frictions (e.g., tariffs, standards and regulations). We show that changes...

The European Emissions Trading Scheme (ETS) is a cap and trade system to curb CO2 emissions. It has caused both direct costs (CO2 allowances) and indirect costs (higher electricity prices) to energy-intensive industries. Moreover, as there is no global CO2 agreement, the ETS could distort the...

The volume collects the essays presented at the 15th Workshop on Public Finance organised by Banca d'Italia in Perugia from 4 to 6 April 2013. The workshop focused on the link between fiscal policy and macroeconomic imbalances and comprised four sessions. The first session concentrated on the...
