A fast algorithm for computing the non-parametric maximum likelihood estimate of a mixing distribution is presented. At each iteration, the algorithm adds new important points to the support set as guided by the gradient function, updates all mixing proportions via a quadratically convergent...

When speculation causes share prices to fluctuate, even the best speculators may do 'hardly better than the comprehensive common-stock averages' (Samuelson). We further demonstrate in this paper that non-speculators can indeed benefit, in terms of both utility and wealth, from speculative price...

Based on an ecosystem view of innovation management and in-depth case studies of firms in China and abroad, a novel paradigm of innovation management—Total Innovation Management (TIM)—is put forward in this paper. This new paradigm draws on three distinct areas of recent research, namely the...

This paper examines the consequences of informational imperfections for economic growth in an overlapping generations model in which agents learn the technological parameters in a Bayesian fashion. Under mild sufficient conditions, beliefs converge to the true value of the technological...
