i am going to assess shortcomings of transaction cost economics (tce) of oliver williamson. my argument is that this analysis suffers from misidentification of the relevant problem of the theory, analytical incoherence, inconsistent empirical support and methodological defects. in formulating coase's fundamental idea, williamson accepts an efficient equilibrium which occurs once forever, t...

Lower previsions defined on a finite set of gambles can be looked at as points in a finite-dimensional real vector space. Within that vector space, the sets of sure loss avoiding and coherent lower previsions form convex polyhedra. We present procedures for obtaining characterizations of these polyhedra in terms of a minimal, finite number of linear constraints. As compared to the previously kn...

Numerical simulations of the temporal evolution of laser light filamentation and stimulated Brillouin forward scattering (SBFS) in plasmas, under conditions that are relevant to laser fusion, are presented and analyzed. Long term unsteady behavior of filaments is observed to be the norm. Temporal and spatial incoherence due to filamentation and SBFS are impressed upon time-independent incident ...

Small coherence (or, incoherence) has nice properties as we shall see now. Assume A has coherence μ < 1. Prove that for all s < 1/μ, A has RIP with parameters s, δ = sμ. Hint: For s-sparse x, write down ‖Ax‖ = (Ax)Ax using inner products of columns of A. Note: There exist deterministic constructions of k×d matrices with incoherence ∼ 1/ √ k, which by the above imply RIP with parameters s = √ k,...

In five studies, the authors examined the effects on cognitive performance of coherence and incoherence between conceptual and experiential sources of affective information. The studies crossed the priming of happy and sad concepts with affective experiences. In different experiments, these included approach or avoidance actions, happy or sad feelings, and happy or sad expressive behaviors. In ...
