Such measures are tested against a complex analysis of the link between innovation and performance for firms listed in the STAR market segment of the Italian Stock Exchange. In so doing, two targets are achieved: (1) the identification of parameters that are relevant for explaining the relationship between innovation and performance for the considered sample, with special focus on innovation type, innovation level and business size; (2) the elaboration of a new methodology – based on information theory – for the analysis of the impact of innovation on performance. The study shows that type of innovation and size play a key role in determining company performance.

To examine this problem, we construct a mechanism to estimate the probability of depletion under a very small set of assumptions. The stock of the resource is assumed to evolve accordingly to a marked temporal process generated by the shocks occurring in the environment. Our setting is eminently theoretical, and constitutes an effective extension of some important models of stochastic growth regarding sustainability and ruin analysis. Furthermore, the validity of the model is supported through the evidence relative to the paradigmatic cases of water resource planning and oil reserves.

The theoretical analysis of the mechanisms driving erroneous assessment of investment performances is explored. The study is supported by the application of Monte Carlo simulations to the remarkable case of structured financial products. Some motivations explaining the popularity of these complex financial instruments among retail investors are also provided. In particular, investors are assumed to compare the performances of different projects through stochastic dominance rules. Unreasonably and in contrast with results obtained by the application of the selected criteria, investors prefer complex securities to standard ones. In this paper, introducing a new definition for stochastic dominance which presents asymmetric property, we provide theoretical and numerical results showing how investors distort stochastic returns and make questionable investment choices. Results are explained in terms of framing and representative effects, which are behavioral finance type arguments showing how decisions may depend on the way the available alternatives are presented to investors.

The aim of this paper is to explain the role of such bonuses in an economic environment with corruption, i.e. in a world where entrepreneurs and tax inspectors are open to bribery. In detail, we analyze the role of a public incentive scheme, where the tax inspector’s bargaining strength is endogenous with respect to an incentive mechanism: indeed the knowledge that even if an entrepreneur does not agree to pay the bribe, s/he can report tax evasion and be partly rewarded for this, increases the tax inspector’s bargaining strength.

More than in other countries, a high percentage of Italian cities are toponyms coming from the name of specific saints (hagiotoponym). The link with Italian religious views is distinct. The statistical analysis of the economic contributions that each hagiotoponym city provides to the Italian GDP is considered. Such an analysis is also based on the comparison with Italian data and is considered with the Theil, Gini, and Herfindahl-Hirschman indices. It is obtained that hagiotoponym cities represent a proxy of the overall Italian reality of medium-sized cities in the case of outliers removal.

The authors propose simple, analytically tractable heterogeneous agent mod- els to show that irrational strategies can survive evolutionary selection. They studied heterogeneity in expectation formation by introducing the concept of Adaptive Belief System (ABS) to model economic and flnancial models. In this paper heterogeneity is assumed, in fact

In this regard, the weight-based convergence of the random matrices and their generalized eigenvalues is obtained under less restrictive requirements for the weights.
