A number of features of innovation diffusion are identified: appropriability, diversity, expectations, selection, learning, and spillover externalities. A dynamic model is formul ated to embed the diffusion question into a more general framework of disequilibrium competition. The model...

In this work, meant as an introduction to the contributions of the task force on Industrial Policies and Development, Initiative for Policy Dialogue, Columbia University, New York, we discuss the role of institutions and policies in the process of development. We begin by arguing how misleading...

This paper presents a critical overview of some recent attempts at building formal models of organizations as information-processing and problem-solving entities. We distinguish between two classes of models according to the different objects of analysis. The first class includes models mainly...

In this work, inspired by Winter [2006], in fact of vintage 1968, we discuss the relation between three dierent levels of analysis of technologies, namely as (i) bodies of problem-solving knowledge, (ii) organizational procedures, and (iii) input-output relations. We begin by arguing that the...

This work discusses the boom and bust dynamics which are a common feature of a large range of different industries. especially but not only new born ones. The common managerial behavior underpinning such dynamics is aggressive capacity expansion in the boom period ultimately yielding excess...

In this work we explore the interplay between entry, selection and innovative learning as determinants of industrial evolution. We propose a model aimed to capture the essential features of learning and competition as drivers of the dynamics. Using both analytical and numerical techniques, we...

This introduction sets in context the works that follow, which are meant to take stock of the theoretical advances and also historical changes since the seminal Arrow (1962) and Nelson (1959). First, we summarize some of the original Arrow--Nelson insights. Second, we map the subsequent...
