It is commonly found that distributions that seem to be lognormal over a broad range change to a power-law (Pareto) distribution for the last few percentiles. The distributions of species abundance, income and wealth as well as file, city and firm sizes are examples with this structure. We...

It has been argued that China may stop financing the US external deficit, appreciate the currency, increase consumption and move its economy away from tradables and towards nontradables. Our two-country model shows that paradoxically this policy option is unattractive if the US authorities keep...

Social capital and corporate social responsibility (CSR) have received increasing attention in research on the role that elements such as trust, trustworthiness and social norms of reciprocity and cooperation may have in promoting socio-economic development. Although social capital and CSR seem...

This paper examines the new SGP rules that should govern fiscal policies of the EMU member countries by means of dynamic models of the debt/GDP ratio. The focus is on factors of heterogeneity and interdependence in the three key variables that may affect the debt/GDP evolution in a multi-country...

In a much cited paper, Wolfgang Keller (Are international R&D spillovers trade-related? Analyzing spillovers among randomly matched trade partners, European Economic Review, 48, 1469-1481, 1998) claims that international R&D spillovers are global and trade-unrelated. In following works, Keller...

In this paper we argue that the consequences of the unemployment risk may be quite different according to the number of persons who depend on the income of the active members, and propose new measures for the economic (in)security related to employment risk, that take into account the household...

Using a laboratory experiment, we investigate the validity of stated risks elicited via the Exchangeability Method (EM) by defining a valuation method based on de Finetti’s notion of coherence. The reliability of risk estimates elicited through the EM has been theoretically questioned because...

Common resources are quasi-public resources, which are rivaled but non excludable in consumption or in appropriation. While the exploitation of common resources has been widely studied in the literature originated by Elinor Ostron’s works (starting from 1990), the study of common resources...

We develop a simple model where exporting firms are characterized by het- erogeneous productivity and may face a liquidity constraint, which in turn is affected by exchange rate changes. This setup is used to analyze exchange rate exposure, i.e. the sensitivity of profits to exchange rate...

Considerable efforts have been made in the recent years to produce detailed topolo- gies of the Internet. While Internet topology data have brought to the attention of a wide and somehow diverse audience of scholars they have been so far over- looked by economic analyses. In this paper we...
