Income Diversification and Bank Performance: Evidence from Italian Banks

Using annual data from Italian banks, we study the link between non-interest revenues and profitability. We find that income diversification increases risk-adjusted returns. Our results provide econometric evidence consistent with current studies on EU banks, but do not support findings on the U.S. experience. In our view, the differences depend primarily on the relative importance of local banks: we find that the relation is stronger at large banks. In addition, we find that there are limits to diversification gains as banks get larger. Small banks can make gains from increasing non-interest income, but only when they have very little non-interest income share to start with. The source of non-interest income is less important than its level.

Engel’s curve and product differentiation: A dynamic analysis of the effects of quality on consumer’s choice

The application of Engel’s Curve in a single-product perspective may dramatically change the role of quality in affecting the dynamics of economic performance. This paper introduces a specification of preferences that regards quality as luxury, and quantity as necessary. The analysis is carried out by using a framework similar to Grossman’s and Helpman ’s (1991), while quality is defined as in Stokey (1988). The resulting consumer’s demand crucially depends on quality. Quality is potentially able to prevent the process, implied by neoclassical models, that leads the value of consumption goods to decline over time. By doing so, quality also affects the consumption bundle shares and the variety-specific consumption growth rates, thus influencing all dynamic quantitative variables of the economy.

THE POSTAL SERVICE IN THE EUROPEAN UNION PUBLIC MONOPOLY OR COMPETITIVE MARKET?: A transaction cost approach

The paper discusses the relevant institutional and economic aspects of the postal service, and analyses both the arguments for abolishing the statutory monopoly and those for retaining it. The main thesis of the paper is that public and private postal services differ from each other in many aspects: transaction costs, the willingness of the customer to pay, market structure, and possibilities of substituting the service with other communication instruments. Therefore, a simple privatisation will not solve per se the efficiency problems of the service. furthermore, the European Commission, which published in 1992 a green paper on postal services, is considering the possibility of harmonising the quality of the service within the EU and gradually reducing the gap in national postal prices. This seems to be an effective device to force firms towards the greater efficiency required in a Continental market. In future, the competition will take place not so much between private firms (more interested in running the high-value segments), as between national public carriers, as shown by the phenomenon of remail.     

US Security Strategy and the Gains from Bilateral Trade

We explore the geo‐strategic determinants of bilateral trade flows between the USA and the rest of the world. We develop a three‐party model of security and trade patterns and use data on military assistance and troop deployments over the 1950–2009 period to validate its predictions. We find that security assistance has significant, positive impacts on the shares of bilateral trade between the USA and the recipient country, results that are robust to issues of reverse causality and hold across different sectors.     

Quasi‐Experimental Evidence on the Effects of Health Information on Preventive Behaviour in Europe

We investigate the effect of information on preventive decisions in a quasi‐experimental setting arising from the implementation of local breast cancer screening programmes in Europe. To identify the causal effect of invitation on preventive uptake, we link administrative public data on regional screening policies to individual data from the Survey of Health Ageing and Retirement in Europe (SHARE) and exploit regional variation in the availability of screening policies and in age eligibility criteria. We find home invitation increases mammography uptakes by around 24%. Significant effects are found when at least 50% of the population is reached by the invitation letter. The stock of health information and the ability to process the information received seem to play a significant role, as the effects of invitation are higher among low educated and lower among cognitively impaired women.     

Asymptotical behavior of finite and possible discontinuous economies

We consider a finite economy in which the data are depending on an exogenous parameter and the utilities satisfy a condition, previously introduced by the authors and called sequential pseudocontinuity, weaker than sequential lower semicontinuity and than sequential upper semicontinuity. We show that the economy has a nice asymptotical behavior, that is: for any sequence (x _n ) _n of exogenous parameters converging to x _o , any convergent subsequence of a sequence of approximate competitive equilibria of converges to an exact equilibrium of .      

The Role of Turnover Costs in the Enforcement of Performance–Related Pay Contracts

Labour contracts which establish performance–related pay are afflicted with the firm's moral hazard problem because of the difficulty in the verifiability of performance by an external authority. Some models have explored the possibility that such contracts could be enforced through a mechanism of the firm's reputation or thanks to an excess of demand in the labour markets (unfilled job vacancies). In this paper a simple model is proposed to show the working of an alternative mechanism for performance–related pay contracts based on turnover costs, borne by firms arising from the process of hiring, training and firing. By sinking a certain amount of resources as turnover costs, employers may credibly promise to pay a bonus, if faced with the worker's threat to quit in the case of cheating, to avoid the loss of specific capital. This provides a formalization of the insight that turnover costs and specific investments might support the enforcement of implicit contracts. The welfare implications of this mechanism are worked out, showing how turnover costs on the one hand reduce the available social surplus but on the other hand increase this surplus by providing incentives for optimal effort.     

Examining the effect of novelty seeking,satisfaction, and destination image on tourists’ return pattern: A two factor,non-linear latent growth model

With many destinations relying on repeat business, intention to revisit has become an important research topic. As revisit intention changes over time, this paper proposes the use of a latent growth curve to model the developmental trajectory of return behavior. The proposed model was tested in two steps in AMOS 16.0 using SEM methodologies to investigate the effects of novelty seeking, destination image and overall satisfaction levels across intent to revisit trajectories using data collected among French, English, and German travelers. Findings indicate that both novelty seeking and low satisfaction among travelers temper immediate intent to return. Conversely, a positive image of the destination enhances both immediate and future intentions to return.     

Central government accounting harmonization in EU member states: will EPSAS be enough?

A highly controversial topic in the EU is the need for harmonized accrual-based standards to improve the quality of public accounts and reduce differences (adjustments) between the micro-(governmental accounting) and macro- (national accounting) levels. This paper shows that a set of high-quality accounting standards, like the future EPSAS, are not going to be sufficient to overcome the present lack of harmonization. The authors explain why this is the case having researched accounting data from 28 EU member states.
