We present a novel argument demonstrating that when trade is characterized by uncertainty the comparative advantages doctrine is misleading and a positive level of diversification is growth enhancing. Applying a result developed in the mathematical biological literature, we show that, in...

This article analyzes, empirically, the link between public procurement and innovation activities by taking into account the moderating effect played by import penetration on public procurement. Using industry-level information on patent applications for 24 countries over the period 1995-2012,...

This paper demonstrates how both quantitative and qualitative results of general, analytically tractable asset-pricing model in which heterogeneous agents behave consistently with a constant relative risk aversion assumption can be applied to the particular case of "linear" investment choices....

In an economic geography model where both a negative pecuniary and a positive technological externality are present, we introduce an explicit dynamics of firms locational choice and we characterize its long run distribution. Our analysis shows that economic activities evenly distribute when the...

This paper is based on Ille 2013. Both papers analyze the same model, but in contrast, this paper does not provide an analytical solution but rather resorts to simulations. This allows the reader, who is familiar with the former article, to retrace the results more thoroughly and without the...

This paper develops a simple dynamic, non-symmetric game between two player populations that can be generalised to a large variety of conflicts. One population attempts to re-write a current (social) contract in its favour, whereas the other prefers to maintain the status quo. In the model's...

The Conflict Analysis approach by Hipel and Fraser (1984) is well equipped to model repeated games. Players are assumed to posses a sequential reasoning that allows them to ( not necessarily correctly) anticipate the reaction of other players to their strategies. An individual’s best response...

We study the co-evolution of asset prices and individual wealth in a financial market populated by an arbitrary number of heterogeneous, boundedly rational agents. Using wealth dynamics as a selection device we are able to characterize the long run market outcomes, i.e. asset returns and wealth...

In this paper we study the dynamics of a simple asset pricing model describing the trading activity of heterogeneous agents in a "stylized" market. The economy in the model contains two assets: a bond with risk-less return and a dividend paying stock. The price of the stock is determined through...

We present an analytical solution for the connectivity of a network model with a "non-simultaneous" linking scheme. Despite its simplicity, this model exhibits node-space correlations in the link distribution, and anomalous fluctuations behavior of the time series of the connectivity variable,...
