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...

In this paper, we apply the bandpass filter to the main Italian and US macroeconomic variables, we estimate cross-correlations with respect to a benchmark indicator of the business cycle, and we compare results with previous empirical analyses. The aim is to investigate on the existence of...

This paper reviews the empirical evidence of the financial sources used by technology-based small firms (TBSFs) in Europe. We shed light on cross-country differences and similarities in the capital structures of TBSFs, in the organization and dynamics of the venture capital industries and...

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 alpha-stable, Normal Inverse Gaussian (NIG), Exponential...

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...

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...

This paper proposes a general framework to account for the divergent results in the empirical literature on the relation between firm sizes and growth rates, and on many results on growth autocorrelation. In particular, we provide an explanation for why traces of the LPE sometimes occur in...

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 work provides an overview of the historical evolution, the organizational forms, and the performances of the stock exchanges and market segments catering to small and growing companies, set up in Europe in the last thirty years. We mainly focus on the Alternative Investment Market (AIM),...

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...
