Choices on museum attendance: An agent-based approach

This paper presents an agent-based model to study museum attendance, with the final aim of evaluating how the rules on free admission affect charged visits. Heterogeneous agents of a population are assumed to make their choices over a bundle of goods and activities which include museum attendance along with other consumption and leisure-time alternatives. Simulations show that larger free-admission rules always lead to an increase in the number of total visits. A specific focus is dedicated to show which conditions let the free admittance policies induce an increment also in charged visits. Agents are characterized in terms of income and education. Addiction to cultural consumption is modelled both with and without reference to education. Specific aspects, such as crowd effects and renovation of exhibitions, are also considered, as features of the museum attendance.     

Firms' efficiency and global value chains: An empirical investigation on Italian industry

This paper investigates the effect of participation in global value chains (GVCs) on firms' efficiency and explores heterogeneity in this impact across different firms, according to GVC governance, positioning in the chain and time length of participation. Our analysis takes advantage of survey data providing information on involvement in GVCs for a large set of Italian industrial SMEs between 2008 and 2012. We employ Data Envelopment Analysis (DEA) to retrieve a measure of firms' technical efficiency (i.e., DEA efficiency scores) and estimate the impact of involvement in GVCs on firms' efficiency through propensity-score matching techniques and truncated regression. Our results show that participation in GVCs induces significant efficiency premia, especially for suppliers, with stronger effects in the case of relational modes of participation.     

Male and Female Recoveries in Medical Malpractice Cases

This study analyzes male and female recovery resulting from medical malpractice injuries to discern the importance to the recovery differential of gender differences in recoveries for medical malpractice injuries. We find that the pattern of recoveries follows one similar to that found in studying wage differentials between males and females. Differences in the relative magnitudes of foregone earnings and nonmarket loses are reflected in the composition of recoveries. In addition, we find a recovery gap in which females receive substantially less in recoveries when they receive male's average compensation for medical malpractice injuries. However, only a small portion of the male and female recovery differential is explained by the characteristics of the claims, leaving a substantial portion of the differential unexplained.     

An offer they couldn't refuse (but probably should have): the ineffectiveness of Italian state subsidies to movie-making

Public financial support to national movie (film) production is typically conditional on very subjective artistic and socio-cultural criteria and objectives. Yet the question remains as to whether state subsidies actually help films at the box office. This paper shows the public grant regime in Italy did not develop the industry as intended, since in an overwhelming number of cases, production losses exceeded subsidy. The subsidy regime was ineffective and wasteful. Specific institutional and political features characterizing the Italian system are important components in this story. The conclusions will be of interest to all countries making commercial films.     

Assessing environmental product declaration opportunities: a reference framework

The growing awareness about environmental issues places greater responsibility on firms to transmit information about the environmental quality of their products. One of the most innovative ways to achieve this objective is through the ‘environmental product declaration’. Unfortunately, from an operating viewpoint, there is a very little evidence on the effects associated with the introduction of this label. In lieu of this context, the paper suggests operating guidelines and a methodological approach for managers who aim to understand under which conditions the EPD can represent a useful tool for the company's competitiveness. In particular, the paper will identify

• 1 the specific peculiarities and requirements of the EPD;
• 2 the EPD parameters of attractiveness, related to its potential costs and benefits;
• 3 an operational framework in order to assess the EPD target audience.

In this respect, an empirical analysis on 17 Italian firms will be carried out. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Identification in Structural Vector Autoregressive Models with Structural Changes,with an Application to US Monetary Policy

A growing line of research makes use of structural changes and different volatility regimes found in the data in a constructive manner to improve the identification of structural parameters in structural vector autoregressions (SVARs). A standard assumption made in the literature is that the reduced form unconditional error covariance matrix varies while the structural parameters remain constant. Under this hypothesis, it is possible to identify the SVAR without needing to resort to additional restrictions. With macroeconomic data, the assumption that the transmission mechanism of the shocks does not vary across volatility regimes is debatable. We derive novel necessary and sufficient rank conditions for local identification of SVARs, where both the error covariance matrix and the structural parameters are allowed to change across volatility regimes. Our approach generalizes the existing literature on ‘identification through changes in volatility’ to a broader framework and opens up interesting possibilities for practitioners. An empirical illustration focuses on a small monetary policy SVAR of the US economy and suggests that monetary policy has become more effective at stabilizing the economy since the 1980s.     

A note on the effects of market power distribution in Cordella and Gabszewicz's Ricardian model

We argue that it is the distribution of market power among agents, rather than the use of market power itself, that may force Ricardian economies into autarky. By applying Baldwin (1948) monopoly equilibrium concepts to the general equilibrium with imperfect competition model analyzed by Cordella and Gabszewicz (1997), we show that the monopoly equilibrium outcome Pareto dominates the oligopoly one. As a consequence, economic efficiency is higher when market power is concentrated in one agent than when it is evenly distributed among few agents.     

Impact of Low‐Skilled Immigration on Female Labour Supply

In this paper, segmenting the market by educational levels, we investigate which native‐born women are more affected by an increase of low‐skilled immigrants working in the household service sector. We present a model of individual choice with home production and, using a harmonized dataset (the Cross‐National Equivalent File), we estimate its main comparative static results. The results suggest that the share of immigrants working in services is positively associated with an increase of native‐born women's labour supply at the intensive margin, if skilled, and at the extensive margin, if unskilled. Moreover, the results show that these effects are larger in countries with less‐supportive family policies.     

Are Commodity Prices Driven by Fundamentals?

Physical scarcity is hardly sufficient to explain commodity price swings. However, despite of clues of commodity market inefficiency in the last decade, excess volatility in commodity markets emerges only under strong assumptions. When we allow for non‐stationarity in commodity prices and time variation in commodity‐specific risk premia, evidence of commodity market inefficiency becomes significantly weaker. Moreover, there is some evidence of commodity‐specific regime changes in commodity markets, with negligible or even positive correlation between efficiency and market liquidity.     

Household financial vulnerability: An empirical analysis

Using survey data, we investigate household financial distress. Specifically, we propose an indicator of financial vulnerability to jointly analyse different features of household financial distress, analysing its socio-demographic and economic determinants. A total number of 3102 Italian households make up the sample.The empirical analysis highlights that for the median level of the financial vulnerability index households already exhibit some important symptoms of financial vulnerability, such as problems in getting to the end of the month or an inability to face unexpected expenses. As regards the determinants of the financial vulnerability index, three findings need to be pointed out. First, the level of debt servicing is positively related to financial vulnerability and the effect is stronger for households holding unsecured debt, i.e. consumer credit. Second, financial vulnerability also increases for impulsive individuals, who may adopt impatient, short-sighted behaviour patterns which make it difficult for them to be fully aware of the consequences of their financial and spending decisions. Third, a higher level of education helps to reduce financial fragility.
