Individual Differences in the Disposition Effect

The authors model the role of personality traits in explaining the disposition effect building on realization utility theory and Big 5 model and moving from an aggregate level to interindividual differences. The experimental analysis, combining NEO Revised Personality Inventory measures with individual financial data from a trading simulation run by 230 individuals in China and Italy, shows that the disposition effect is driven by 2 distinct psychological processes, one related to holding losers and the other to selling winners. These 2 behavioral mechanisms are uncorrelated and influenced by different personality traits. Controlling for different demographic variables, the authors show (a) a greater sensitivity of the rewarding system that motivates “extroverts” to quickly sell the stock at gain to receive a burst of utility; (b) a tendency for “conscientious” subjects to suppress impulsivity, patiently waiting for higher cumulative returns; and (c) the importance of “openness to experience” to better value information to achieve higher outcomes.     

Industrial districts and internationalization: the case of the agri-food industry in Modena,Italy

The paper explores the structural changes, in response to internationalization, in an important traditional activity (food chain, meat processing) in a typical ‘district area’. In the paper, attention is focused on the ‘Institutional structure of production’ (Coase, R. 1992 Coase, R. 1992. The institutional structure of production. American Economic Review, 82(4): 713–719. [Web of Science ®] , [Google Scholar]) and the cluster is considered as a whole, as a complex economic player, capable of generating coherent action, regulated by institutional mechanisms, and founded on a set of ‘public assets’ which make up its ‘social capital’.

The paper is based on many empirical studies and surveys aimed at exploring the structure of SMEs and the role of the local institutions: the changes observed over time and in response to internationalization underline the reinforcement of the activity's cluster configuration.

These features emphasize the existence of a specific unit of analysis, indivisible from the individuals which constitute it. The discussion touches on the classical themes of the efficiency of the net-economy based on SMEs, and their prospects in a context of growing globalization.

The paper does not aim to enter into the debate on the origins and mechanism of innovation. However, the case study does illustrate the strength of the hypothesis of a unit of analysis different from the firm for discussion of a number of topics: some empirical examples of innovation, of significance for the economic consolidation of the ID, highlight the importance of district relationships in the production and spread of innovation.     

A simple model of vertical search engines foreclosure

By means of a simple model with consumers' search, the paper analyzes a monopolistic general search engine incentives to bias organic and sponsored search results in order to favor an integrated website. In the model, manipulation takes place whenever the general search engine places prominently its own vertical search engine instead of the most relevant for consumers. The main finding is that the incentives to manipulate search results are stronger in the organic search case. In the sponsored search case the general search platform internalizes the impact of manipulation on profits, since the less a prominent vertical search engine is relevant to consumers, the lower is the price-per-click that the general search engine can charge.     

Internationalization and industrial districts: evidence from the Italian automotive supply chain

In this paper we focus on the determinants of internationalization and, in particular, on the specific role played by the agglomeration of small and medium sized enterprises (SMEs) through their proximity to a large firm. We study the characteristics of the internationalization process in a representative sample of 786 firms in the Italian automotive supply chain. After building an Internationalization Strategy Index (ISI), we perform a multinomial logit econometric analysis. The main findings of the empirical analysis are: (a) Italian automotive supplier firms mainly go in the foreign markets through export, i.e. the simplest internationalization mode; (b) as predicted in the literature, individual firm characteristics play a significant role in the probability of internationalization; (c) firms located in the province of Turin, where the dominant car assembler (Fiat) in Italy has its headquarters, or more generally, in large automotive industry districts, enjoy a clear localization advantage; (d) interestingly, we also find that internationalization is negatively correlated with the share of Fiat in suppliers’ sales, and that suppliers located in a district and less dependent on Fiat are also those adopting the most advanced internationalization strategies.     

State intervention and economic growth in Southern Italy: the rise and fall of the ‘Cassa per il Mezzogiorno’ (1950–1986)

In the second half of the twentieth century, the Italian government carried out a massive regional policy in southern Italy, through the State-owned agency ‘Cassa per il Mezzogiorno’ (1950–1986). The article reconstructs the activities of this agency, making use of its yearly reports and of national and local archives. The Cassa was effective in the first two decades, thanks to substantial technical autonomy and, in the 1960s, to a strong focus on industrial development; however, from the 1970s it progressively became an instrument of waste and misallocation. At the local level, we find significant differences between the southern regions, and correspondence between the quality of state intervention and the regional patterns of GDP and productivity.     

Interest rate risk estimation: a new duration-based approach

Duration is widely used by fixed income managers to proxy the interest rate risk of their assets and liabilities. However, it is well known that the convexity of the price-yield relationship introduces approximation errors that grow with changes in yield. In this article we suggest a new approach, ‘discrete duration’, which significantly improves upon the accuracy of traditional duration methods and achieves a level of accuracy close to the more complex ‘duration-plus-convexity’ measure. In particular, discrete duration performs particularly well for long dated and low coupon rate bonds where the estimation error is impressively close to zero.     

Information versus imitation in a real-time agent-based model of financial markets

This paper presents an agent based model of a financial market with a real-time engine, whose operation replicates the official time schedule of Borsa Italiana S.p.A. Simulated time series are compared with empirical data at different time scales (ticks, 1 s, 1 min, 5 min) in order to check the compliance of the model with some stylized facts. The modeled market structure is a dynamic multiplex with two layers: the first one is a star network, whose hub is the market maker (i.e., the owner of the venue holding the order book), where transactions are executed; the second one is designed according to different topologies, representing social interactions, where investors decide their behavior according to informative flows. The effect of imitation on market stability is discussed and some policy implications are provided.

     

The missing shock: the macroeconomic impact of British Privatizations

In this paper the impact of privatization on macroeconomic performance in the United Kingdom is tested using quarterly data from 1979 to 1999. Privatization proceeds have been included in a simple analytical framework dealing with both demand and supply-side of the economy. Multivariate cointegration techniques have been used in order to consider the nonstationarity of the time series involved. The empirical results show that privatizations have no long-run effects on output in the UK. This result is consistent with microeconomic evidence that shows that in the UK ownership change per se had little impact on long term productivity trends. Moreover it is found that privatization proceeds have contributed to sustaining public expenditures.     

The role of institutional investors in public-to-private transactions

In Italy, as in many other European countries, listed firms will normally go dark through controlling owner-initiated tender offers. We find that institutional investors play a central role in the bid process and can protect minority shareholders from being frozen out in the bid. Specifically, tender offers are less likely to succeed when a firm has institutional investors in its ownership structure. When public-to-private offers are accepted, bid premiums are significantly greater if a financial institution (particularly when it is foreign, independent or activist) has a stake in the firm. We explore the effect of a number of hitherto unexplored factors on the takeover premium and find that shareholder agreements facilitate public-to-private acquisitions. Other factors, such as a threat to merge the target if the bid fails, or external validation of the offer price, have no impact on either the likelihood of delisting or the premium paid by the bidder.     

The Determinants of Regulatory Compliance: An Analysis of Insider Trading Disclosures in Italy

This paper investigates the determinants of regulatory compliance in corporate organizations. Exploiting a unique enforcement and reporting framework for insider trading in Italy, we present three main findings. First, board governance, such as chief executive–chairman duality and the proportion of non-executive directors, does not increase the propensity of firms to comply with regulation. Second, family firms and firms with a high degree of separation of ownership from control are most likely to comply with regulation. Third, corporate ethos is more important in predicting regulatory compliance than explicit corporate governance structures.
