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...

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...

The paper compares the properties of market dynamics, under different trading protocols. At an empirical level, we present some evidence stemming from the comparison between different intra-daily trade regimes within the world largest Stock Exchanges. Such evidence also motivates the...

This paper builds upon a view of economic system and individual economic organization as problem-solving arrangements and presents a simple model of adaptive problem-solving driven by trial-and-error and collective selection. The institutional structure, and in particular its degree of...

The last quarter-century has seen the rise of an almost religious belief in the efficacy of market organization of economic activity. While there are strong empirically supported reasons for a bias toward market organization, particularly considering the alternatives, there are many areas of...

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 paper analyses the properties and outcomes of competitive dynamics in industries characterized by heterogeneous firms and continuing stochastic entry. A formal analytical apparatus is developed, able to derive some generic properties of the underlying competition process combining persistent...

This study analyzes incumbent entry timing decisions in new markets in the case of Encryption Software (ES). In ES first technological movers were slow to enter the downstream market, losing their initial advantages to the benefit of newcomers. This work tests the hypothesis that this...

The paper analyses the birth of the Encryption Software Industry (ESI), a new niche in the software industry. Using a Chandlerian perspective, this work reports the main facts about firm entry and growth, with a particular focus on start-up strategies and actions. Since scale economies do not...

This paper analyzes the birth of the Encryption Software Industry (ESI), a new market niche in the software industry. This work will report the main facts of entry and exit process, focusing on firm post-entry performance, on the different phases of competition during the industry evolution, and...
