Do Private Equity Investors Create Value for Italian Initial Public Offerings?

This study analyses the role of private equity (PE) backing in initial public offerings (IPOs) using a dataset of 227 companies that went public on the Milan Stock Exchange between January 1995 and December 2007. The evidence rejects the certification and monitoring hypotheses and provides considerable support for the market power hypothesis. In accordance with Chemmanur and Loutskina (2006) , we suggest that PE investors exploit their relationships with the key IPO market players to attract attention to the IPOs of firms backed by PE, thus obtaining a higher equity valuation (both in the IPO and in the secondary market).     

Arbitraging Arbitrageurs

This paper develops a theory of strategic trading in markets with large arbitrageurs. If arbitrageurs are not well capitalized, capital constraints make their trades predictable. Other market participants can exploit this by trading against them. Competitors may find it optimal to lend to arbitrageurs that are financially fragile; additional capital makes the arbitrageurs more viable, and lenders can reap profits from trading against them for a longer time. The strategic behavior of these market participants has implications for the functioning of financial markets. Strategic trading may produce significant price distortions, increase price manipulation, and trigger forced liquidations of large traders.     

Social Preferences, Skill Segregation, and Wage Dynamics

We study the earning structure and the equilibrium assignment of workers to firms in a model in which workers have social preferences, and skills are perfectly substitutable in production. Firms offer long-term contracts, and we allow for frictions in the labour market in the form of mobility costs. The model delivers specific predictions about the nature of worker flows, about the characteristics of workplace skill segregation, and about wage dispersion both within and across firms. We show that long-term contracts in the presence of social preferences associate within-firm wage dispersion with novel "internal labour market" features such as gradual promotions, productivity-unrelated wage increases, and downward wage flexibility. These three dynamic features lead to productivity-unrelated wage volatility within firms.     

Using Neural Data to Test a Theory of Investor Behavior: An Application to Realization Utility

We conduct a study in which subjects trade stocks in an experimental market while we measure their brain activity using functional magnetic resonance imaging. All of the subjects trade in a suboptimal way. We use the neural data to test a “realization utility” explanation for their behavior. We find that activity in two areas of the brain that are important for economic decision‐making exhibit activity consistent with the predictions of realization utility. These results provide support for the realization utility model. More generally, they demonstrate that neural data can be helpful in testing models of investor behavior.     

To Majority through the Search for Unanimity

The relative majority rule is characterized, when there are only two alternatives, in terms of axioms of unanimity, reducibility, ontoness (which expresses citizen sovereignty), and no veto power (a weakening of almost unanimity). The strongest axiom is reducibility, which embodies the preference aggregation procedure that successively synthesizes two divergent preferences until divergence disappears and, therefore, unanimity can be applied.     

Inward investment and endogenous development. The convergence of the strategies of large firms and territories?

Inward investment is often understood as an inadequate instrument for self-sustained growth and as being responsible for the insufficient development of peripheral areas. Globalization and increasing competition within the markets, however, changed the firms' and regions' adjustment environment, and led to the convergence of spatial strategies of the large innovative firms and the development strategies of regional and local governments. This process contributes toward the integration of the external firms within local productive systems and, therefore, large innovative firms can play a relevant role in endogenous development processes. Although the convergence of strategies is not a phenomenon that can be generalized for all types of firms and territories, a new line of action opens up that permits improved productive restructuring and economic development, even in less favoured and peripheral regions.
