A generalized approach to optimal hedging with option contracts

In this paper, we develop a theoretical model in which a firm hedges a spot position using options in the presence of both quantity (production) and basis risks. Our optimal hedge ratio is fairly general, in that the dependence structure is modeled through a copula function representing the quantiles of the hedged position, and hence any quantile risk measure can be employed. We study the sensitivity of the exercise price which minimizes the risk of the hedged portfolio to the relevant parameters, and we find that the subjective risk aversion of the firm does not play any role. The only trade-off is between the effectiveness and cost of the hedging strategy.     

Multi-agent technologies in economics

This paper summarizes some of the trends in the use of multi-agent technologies in economics. Multiple agent systems, fuzzy sets and neural networks are critical tools used to investigate the emerging economics research agenda related to data mining, dynamic markets stock selection and bank stress testing. This paper reviews the contributions of four such examples.     

International crises,instability periods and contagion: the case of the ERM

In this article we propose a two step procedure for modeling the propagation of financial shocks. The first step consists in the estimation, by means of SWARCH models, of the conditional probability of being in a period of high volatility, while in the second step such indicators are included in a structural simultaneous equations models for interdependences among different countries. The results show that episodes of financial crisis effectively happened during periods of high volatility and that such measures of instability are important in explaining the propagation of devaluation expectations between six European Countries during the ERM period.

A note on the sensitivity analysis of the internal rate of return

In this note we discuss the sensitivity analysis of the internal rates of return (IRR). We show that the use of partial derivatives can be misleading in the identification of key drivers of an investment project's performance. To remedy this shortcoming, we propose the use of an alternative sensitivity measure called the Differential Importance Measure. The analysis shows that, even if the theoretical conditions for using the Net Present Value or the IRR as valuation criteria apply, the sensitivity analysis results for the two indicators may differ.

The Economic Significance of the Film Business: An Empirical Analysis of the Italian Market

Most studies indicate Hollywood's economic and financial leadership in the movie markets from the 1910s onward. There is a shortfall in the literature concerning the analysis of the efficacy of other minor film industries. This article examines the Italian film industry in the 1990s and beginning of the twenty‐first century. The research suggests that the Italian film industry is very risky and unpredictable, but while the extreme uncertainty surrounding the business is offset by the considerable economic success that Hollywood movies achieve at the box office, as indicated by previous literature contributions, a different business scenario emerges in Italy. The value of this article is first represented by the data used—provided by the Osservatorio of Cinecittà—which is unique and has not been published before. © 2016 Wiley Periodicals, Inc.
