3T3 cells were established after a temporary dip in reproductive ability (top); once established they entered a resting state at a low cell density (bottom). G RE EN George Todaro and Howard Green establish the 3T3 cell line— the first well behaved, contact-inhibited cell line. In this mess of uncontrolled growth it was difficult or impossible to pick out cells that had been transformed after i...

The Todaro Paradox Revisited The Todaro Paradox states that policies aimed at reducing urban unemployment are bound to backfire: they will raise rather than reduce urban unemployment. The aim of this paper is to reexamine this paradox in the context of efficiency wage and search-matching models. For that, we study a policy that consists in decreasing the urban unemployment benefit. In an effici...

The tendon of Todaro, found in the right atrium of the heart, has considerable clinical importance in the fields of both cardiac surgery and invasive cardiology. The goal of this study was to examine the occurrence and degree of development of the tendon of Todaro in humans. Research was conducted on material consisting of 160 human hearts of both sexes from the age of 14 Hbd to 87 years of age...

Excerpt] In terms of the current discussion of pro-poor economic growth, the Harris-Todaro model and other multi-sector labor market models can help policy-makers avoid two mistakes. One is to assume that development efforts should necessarily be channeled to the sectors where the poor are. The other is to assume that efforts should necessarily be focused on getting the poor out of the sectors ...

Overwhelming urban migration occurred so rapidly in many developing countries that widespread unemployment and squalid living conditions are commonplace. For many of these countries, stopping urban migration has become a major policy. Two models propose 2 different theories of urban unemployment. Todaro's short-term effects model concludes that job creation actually causes unemployment. Tod...

Discrete radiofrequency lesion at the atrial insertion site of the tendon of Todaro in the perfused rabbit preparation lengthens A-H interval, mimicking fast pathway input ablation. This study attempts to define the cellular electrophysiology of the ablation region prior to and after the elimination of fast AV node conduction. In six superfused rabbit AV node preparations, the cellular electrop...
