The model that this paper sets out is based on a combination of the Schumpeterian creative destruction and the neo-Austrian notion of market process. It gives a formalization of the succession innovation-structural organization and its endogenous mechanism, crucial to explain economic growth and...

We build an evolutionary model of currency crises incorporating learning through imitation and experimentation by heterogeneous agents. Foreign currency speculators in the model interact and learn over time through experimentation. Drawing on results from game theory, we show that the resulting...

By studying the effect of different patterns of demand in an evolutionary selection model this paper shows how product differentiation reduces competitive selection pressure and thus increases the chances for the coexistence of firms. With the example of a duopoly it shows that: (1) a monopoly...

What causes a government to adopt a new program or policy? Despite a large number of empirical studies available to date, the relative importance of various determinants remains obscure because of difficulties of statistical identification. We present an experimental setting to study the...

This paper explores ongoing debates about the role that codified forms of knowledge play in fostering innovative behaviour. It aims to provide an empirical exploration of the use of codified sources of information for innovation at the firm and sectoral level. Despite considerable interest in...

This paper presents a simple evolutionary model to study the diffusion patterns of product innovations for consumer goods. Following a Veblenian theme, we interpret consumption as a social activity constrained by social norms and class structure. Societies that allow for more behavioral variety...

The paper uses a two-stage, multi-agent simulation model to examine the conditions under which technological successions can occur in the presence of network externalities. Data is used to identify a robust econometric model of the probability of succession. Four key factors are identified....

I propose a dynamic duopoly model where firms enter simultaneously but compete hierarchically á la Stackelberg at each instant over time. They accumulate capacity through costly investment, with capital accumulation dynamics being affected by an additive shock the mean and variance of which are...
