Motivated by psychological evidence that attention is a scarce cognitive resource, we model investors’ attention allocation in learning and study the effects of this on asset-price dynamics. We show that limited investor attention leads to category-learning behavior, i.e., investors tend to process more market and sector-wide information than firm-specific information. This endogenous structure...

This paper estimates a dynamic model of the world oil market and tests whether OPEC countries colluded and whether non-OPEC countries behaved oligopolistically over the period 1970-2004. The model generates estimates of the shadow price of the resource with minimal functional form assumptions. Results support oligopolistic behavior among non-OPEC producers and collusion among OPEC producers exc...

We propose a dynamic model for studying the time evolution of fish stocks in an environment divided into two adjacent zones with different fishing policies. We analyze two particular harvesting methods: constant fishing effort and profit maximization. In this case, some agents engage in competition based on maximization of individual profit whereas others cooperate. The asymptotic behavior of t...

I adopt the distribution dynamics framework to study labor productivity convergence, in the period 1980-1995, among 28 developed and developing countries, in different manufacturing sub-sectors, identified, as according their technological content into Resource Based, Low Technology, Medium Technology and High Technology. I find that, exception made for High Technology and Manufacturing as a wh...

In smooth exchange economies with a continuum of agents, any Walrasian mechanism is Pareto efficient, individually rational, anonymous, and strategy-proof. Barberà and Jackson’s recent results imply that no such efficient mechanism is the limit of resource-balanced, individually rational, anonymous and non-bossy strategy-proof allocation mechanisms for an expanding sequence of finite economies....

Noncognitive Abilities and Within-Group Wage Inequality This paper argues that endogenous restructuring processes within firms towards productivityenhancing human resource activities, triggered by advances in information and communication technologies (ICT) and rising supply of educated workers, are typically associated with higher demand for noncognitive abilities. Consistent with the evolutio...

Effort-biased technological change and other explanations for work intensification are investigated. It is hypothesised that technological and organizational changes are one important source of work intensification and supportive evidence is found using establishment data for Britain in the 1990s. Work intensification has also been stimulated by the use of highcommitment human resource policies...

The paper presents a model of educational production which tries to make sense of recent evidence on effects of institutional arrangements on student performance. In a simple principal-agent framework, students choose their learning effort to maximize their net benefits, while the government chooses educational spending to maximize its net benefits. In the jointly determined equilibrium, school...

Grammar formalisms built on the notion of word-to-word dependencies make attractive alternatives to formalisms built on phrase structure representations. However, little is known about the formal properties of dependency grammars, and few such grammars have been implemented. We present results from two strands of research that address these issues. The aims of this research were to classify dep...

Resource-rich countries have tended to be autocratic and also have tended to use their resource wealth badly. The neoconservative agenda of promoting democratization in resource-rich countries thus offers the hopeful prospect of a better use of their economic opportunities. This paper examines whether the effect of democracy on economic performance is distinctive in resource-rich societies. We ...
