Minimum Average Cost Clustering

A number of objective functions in clustering problems can be described with submodular functions. In this paper, we introduce the minimum average cost criterion, and show that the theory of intersecting submodular functions can be used for clustering with submodular objective functions. The proposed algorithm does not require the number of clusters in advance, and it will be determined by the ...

The Opportunity Cost of Capital

The opportunity cost of the capital invested in pharmaceutical research and development (R&D) to bring a new drug to market makes up as much as half the total cost. However, the literature on the cost of pharmaceutical R&D is mixed on how, exactly, one should calculate this "hidden" cost. Some authors attempt to adopt models from the field of finance, whereas other prominent authors dismiss thi...

Average cost temporal-difference learning

We propose a variant of temporal-difference learning that approximates average and differential costs of an irreducible aperiodic Markov chain. Approximations are comprised of linear combinations of fixed basis functions whose weights are incrementally updated during a single endless trajectory of the Markov chain. We present a proof of convergence (with probability 1), and a characterization o...

Capital Account Liberalization, The Cost of Capital, and Economic Growth

Capital-account liberalization was once seen as an inevitable step along the path to economic development for poor countries. Liberalizing the capital account, it was said, would permit financial resources to flow from capitalabundant countries, where expected returns were low, to capital-scarce countries, where expected returns were high. The flow of resources into the liberalizing countries w...
