This study proposes the theory of technological parasitism that may be useful for bringing a new perspective to explain and generalize the evolution of technology directed to sustain competitive advantage of firms and nations. Technological parasitism explains the relationship of mutualistic...

This study investigates the failure in project management due to bounded rationality of organizations in the presence of complex and uncertain environments. Examples of failure in project management are described from pharmaceutical sectors (e.g., antibody drugs for Alzheimer’s disease), space...

This paper studies human-capital formation, labor-supply, and retirement decisions associated with four alternative regimes of social security. We implement a theoretical model with overlapping generations of households and two different ability types within each generation. We find that with a...

We present a theory on migration of dual-earner couples, and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases in the earnings of the primary earner. The effect of the earnings of the secondary earner may go either way....

We develop a theoretical model regarding the migration of dual-earner couples and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases with the income of the primary earner, whereas the income of the secondary earner may...

We study the efficiency and distributional consequences of establishing and abolishing the draft in a dynamic model with overlapping generations, taking into account endogenous human capital formation as well as government budget constraints. The introduction of the draft initially benefits the...

Using panel data for 78 countries of origin we examine the impact of student flows to the United States on subsequent migration there over the period 1971-2001. What we find is that the stock of foreign students is an important predictor of subsequent migration. This holds true whether or not...
