Multiple versus Single Banking Relationships: Theory and Evidence

A theory of the optimal number of banking relationships is developed and tested using matched bank-firm data. According to the theory, relationship banks may be unable to continue funding profitable projects owing to internal problems and a firm may thus have to refinance from nonrelationship banks. The latter, however, face an adverse selection problem, as they do not know the quality of the project, and may refuse to lend. In these circumstances, multiple banking can reduce the probability of an early liquidation of the project. The empirical evidence supports the predictions of the model.     

Bank Fragility and International Capital Mobility

The paper presents a model of a small open economy with a fragile banking sector and imperfect international capital mobility. In this model, increased international integration of the market for bank deposits makes bank runs more likely, resulting in a welfare loss for the business sector. Bank depositors may gain or lose depending on the parameters. When depositors gain, whether the gains exceed the losses to the business sector depends on the size of the holdings of foreign assets relative to the deadweight costs of bank runs. Thus, limited international financial integration may not be desirable.     

Empirical models of short-term debt and crises: Do they test the creditor run hypothesis?

A positive correlation between short-term debt and crises has been interpreted as evidence in favor of self-fulfilling creditor runs, which have been blamed for financial crises in developing countries. We show that this correlation can also be explained by a standard model of optimal borrowing without creditor runs. In such a model, imposing capital controls on short-term external debt is not Pareto-improving.     

Urban rail systems investments: an analysis of the impacts on property values and residents’ location

Light rail, metro and other urban rail transit systems can play a significant role in improving the attractiveness and quality of urban public transport. They can influence the attractiveness of locations near the stations and improve accessibility for these locations. Furthermore urban rail can improve a location’s attractiveness by its image effect: it makes a station appear modern and dynamic, and thus raises the status of this location.This paper summarises findings on the land-use and economic impacts of the urban rail system of the city of Naples over time and space. It examines changes in residential and non-residential (offices and retail) property prices around the newly built stations between 2001 and 2008 as well as the changes in the number of residents for the same station catchment areas. Ad hoc station control areas have been specified in order to compare the results of these changes. Results show that values in station control areas are lower than those of those of the stations catchment areas.     

The simple dynamics of a debt crisis

Optimal growth path of an ‘impatient’, neoclassical economy is studied, when creditors impose a credit ceiling to prevent debt repudiation. The ceiling becomes binding in finite time. When the credit-constrained regime begins, foreign capital inflows and domestic investment fall abruptly. Output per-capita, consumption, and real wages gradually decline, while the real interest rate rises. These results show that debt crises, in which high external debt is associated to low growth, can occur even in the absence of unanticipated shocks, policy mistakes, or ‘debt overhang’ effects. If distortionary policies cause ‘impatient’ behavior, the model is consistent with chronic capital flight in the debtor country. (JEL F34, F32)     

The Market Reorientation of Farms: The Case of Olive Growing in the Nebrodi Area

In addition to safeguarding the landscape, olive growing makes a unique contribution to protecting the environment and the agricultural ecosystem. Olive growing in mountainous and hilly areas is severely constrained by structural limitations. Rural tourism can be a potential strategy to increase the competitiveness of olive-growing activities. After an initial analysis of the relationship between landscape, tourism, and olive growing, this study focused on olive growing in the Nebrodi area. In particular, we examined two case studies of olive farms to analyze the related production costs and market positioning strategies.     

A Good Opening: The Key to Make the Most of Unilateral Climate Action

In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the environmental benefits of cooperation, the incentive to expand energy consumption, and the incentive to adopt the cleaner technologies introduced by the coalition. Using an Integrated Assessment Model with a game-theoretic structure we find that the equilibrium abatement of the coalition composed by OECD countries would be moderate, in line with the Pledges subscribed in Copenhagen, but increasing. The mitigation strategy would consist of investments in energy R&D and deployment of cleaner technologies with high learning potentials. International knowledge and technology externalities would facilitate the diffusion of cleaner technologies in non-signatory countries, offsetting the free-riding incentive and reducing their emissions. If the OECD group curbs emissions beyond the optimal equilibrium level, reaching reduction rates between 40 and 45 % below 2005 levels in 2050, the benefits of technology externalities would no longer compensate the effect of lower fossil fuel prices. Our results suggest that a moderate unilateral climate policy could induce a virtuous behaviour in non-signatory countries and that policies promoting the international transfer of technologies and knowledge could represent an effective complement to mitigation targets.     

THE INNOVATION‐EMPLOYMENT NEXUS: A CRITICAL SURVEY OF THEORY AND EMPIRICS

Understanding whether technical change is beneficial or detrimental for employment is at the center of the policy debate, especially in phases of economic recession. So far, the effects of innovation – in its manifold declinations and intrinsic complexity – on labor demand have proven to be not unequivocal. This essay critically reviews the role of technical change in shaping employment dynamics at different levels of aggregation. First, it disentangles theoretically the role of different compensation mechanisms through which employment adjusts after an innovation is introduced. Second, it critically presents the most recent empirical evidence on the topic, with a focus on methods and limitations. Finally, it provides an attempt to conceptualize a number of stylized facts and empirical regularities on the innovation‐employment nexus.
