Bayesian learning provides the core concept of processing noisy information. In standard Bayesian frameworks, assessing the price impact of information requires perfect knowledge of news' precision. In practice, however, precision is rarely dis- closed. Therefore, we extend standard Bayesian...

The paper, as such a draft of a chapter for the second edition of the 'Handbook of Economic Socielogy', Edited by Neil J. Smelser and Richard Swedberg, is meant to offer some sort of roadmap accross a few fields of investigation concerning the relationships between technological learning and...

We study the dynamics of a Lucas-tree model with finitely lived agents who "learn from experience." Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...

The empirical analysis of the micro links between trade and knowledge diffusion allows us to distinguish among the key predictions of the theoretical literature on endogenous growth. This literature postulates that total factor productivity (TFP) is higher when trade gives access to a wider or...

Bayesian learning provides a core concept of information processing in financial markets. Typically it is assumed that market participants perfectly know the quality of released news. However, in practice, news' precision is rarely disclosed. Therefore, we extend standard Bayesian learning...

The aim of this work is to investigate the role played by the so-called 'globalization' processes of the last couples of decades on the international patterns of technological learning and on the distribution of incomes and growth. First, we re-assess the evidence on the general patterns of the...

In this work, we present an assessment of the nature and impact of current globalizing tendencies at various levels of observation. The evidence in this respect suggests that it has mostly concerned financial flows (especially short-term ones); to some extent trade flows; and only to very...

We investigate the controversial issue whether unemployment is related to productivity growth in the long run, using U.S. data in a framework of infrequent mean shifts. Tests find (endogenously dated) shifts around 1974, 1986, and 1996, system techniques indicate that the shifts are common...

An evolutionary model of the product life cycle is applied to derive the experience curve and the market size of (expensive) durable goods. The experience (learning) curve suggests that the real costs per unit decrease with an increasing cumulative output (Henderson's law). Based on the idea...

This paper develops an equilibrium model of speculative bubbles that can be used to explore the role of various policies in either giving rise to or eliminating the possibility of asset bubbles, e.g. restricting the use of certain types of loan contracts, imposing down- payment restrictions, and...
