This paper investigates opinion dynamics and social in uence 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...

Population learning in dynamic economies has been traditionally studied in over-simplified settings where payoff landscapes are very smooth. Indeed, in these models, all agents play the same bilateral stage-game against any opponent and stage-game payoffs reflect very simple strategic situations...

The paper, largely based on the introduction to Dosi (2012), elaborates on the main interpretative ingredients, methodology and challenges ahead of the evolutionary research program in economics. Telegraphically, such a perspective attempts to understand a wide set of economic phenomena -...

The paper discusses some fundamental features of the 'Simonian' research program in microeconomics and compare them with two streams of thought which find their roots into Simon's pathbreaking work since the '50s and '60s, namely Transaction Cost Economics and Evolutionary Economics. One argues...

The paper is based on the acknowledgement that properties of markets stemming from features of demand are too frequently overlooked in the economic literature, and a re-balancing is necessary to properly account for theoretical and empirical phenomena. We sustain that one of the most relevant...

The term "bounded rationality" is meant to connote the reasoning capabilities of an actor who, on the one hand, has a goal to achieve and an at least partially formed theory as to how to achieve it, and on the other hand, that the theory is somewhat crude, likely will be revised in the course of...
