This paper investigates opinion dynamics and social influence in directed communication networks. We study the theoretical properties of a boundedly rational model of opinion formation in which individuals aggregate the information they receive from their neighbors by using weights that are a...

This work analyzes the mutual dependence linking digital platforms, i.e., 'Big Tech', and the military apparatus. Three main elements are at the roots of such dependence: an 'originary linkage' binding the development of digital platforms with governments' R&D military efforts, the critical...

The paper applies the radical view of Monopoly Capitalism to the digital platform economy. Based on the seminal ideas of Hymer and Zeitlin that led Cowling and Sugden to define the large monopolistic firm as a means to plan production from a unique centre of strategic decision-making, we attempt...

We analyze art pricing in a unique dataset on Madrid inventories between 1600 and 1750. Hedonic regressions reveal a number of interesting facts about the taste of Baroque Spanish collectors and the imports of foreign paintings. The hedonic price index shows an impressive increase in the price...

Based on the literature on public procurement regulation, we use an Agent-Based Model to assess the performance of different selection procedures. Specifically, we aim at investigating whether and how the inclusion of reputation of firms in the public procurement selection process affects the...

We build an agent-based model to study how the interplay between low- and high- frequency trading affects asset price dynamics. Our main goal is to investigate whether high-frequency trading exacerbates market volatility and generates flash crashes. In the model, low-frequency agents adopt...

In this paper we explore the effects of alternative combinations of fiscal and monetary policies under different income distribution regimes. In particular, we aim at evaluating fiscal rules in economies subject to banking crises and deep recessions. We do so using an agent-based model populated...

This paper presents the family of the Keynes+Schumpeter (K+S, cf. Dosi et al, 2010, 2013, 2014) evolutionary agent-based models, which study the effects of a rich ensemble of innovation, industrial dynamics and macroeconomic policies on the long-term growth and short-run fluctuations of the...

In this work we analyze the short- and long-run effects of fiscal austerity policies, employing an agent-based model populated by heterogeneous, boundedly-rational firms and banks. The model, in line with the family of "Keynes+Schumpeter" formalism, is able to account for a wide array of macro...

Simulated models suffer intrinsically from validation and comparison problems. The choice of a suitable indicator quantifying the distance between the model and the data is pivotal to model selection. However, how to validate and discriminate between alternative models is still an open problem...
