The first part of this paper establishes some new pieces of evidence on the dynamics of prices and volumes in wholesale electricity day-ahead markets (NordPool, APX, Powernext). The growth of prices is more strongly autocorrelated than the growth of volumes; it is more more heavy-tailed; and its...

This paper contributes to characterizing the probability density of the price returns in some European day-ahead electricity markets (NordPool, APX, Powernext) by fitting some flexible and general families of distributions, such as the α-stable, Normal Inverse Gaussian (NIG), Exponential Power...

The evidence of volatility-price dependence observed in previous works (Karakatsani and Bunn 2004; Bottazzi, Sapio and Secchi 2005; Simonsen 2005) suggests that there is more to volatility than simply spikes. Volatility is found to be positively correlated with the lagged price level in settings where...

In uniform price, sealed-bid day-ahead electricity auctions, the market price is set at the intersection between aggregate demand and supply functions built by a market operator. Each day, just one agent - the marginal generator - owns the market-clearing plant. Day-ahead auctions are moreover...

This work introduces a special issue of the Journal of Economic Behavior and Organization on the emergence and impact of market institutions in wholesale fish markets. The analysis of fish markets has a respectable pedigree also in terms of the description of how they function. A major advantage...

This paper reviews the evidence on financing technology-based small firms (TBSFs) in Europe. The main findings in the literature are the 1) European TBSF's finance new investments by relying primarily on internal funds, due to capital market failures induced by asymmetric information; 2)...

It is widely accepted that in liberalized electricity markets log-returns display fat-tailed densities. Besides qualitative assessments, so far precise characterizations of the shape of the distribution have been seldom provided. In this work, we characterize the conditional and unconditional...

Harberger's 'A Vision of the Growth Process', Presidential Address at the 1998 Annual Meeting of the American Economic Association, provides evidence that contributions to aggregate real cost reduction (RCR) are concentrated in a small number of industries. According to Harberger, this is...
