ion. We suggest that formal methods of real option pricing have an important stake in the domain of positive theory regarding the market valuation of investments under uncertainty. As happens in science, the extension of these methods to other domains confronts new data and modeling challenges. Several innovations have been

Valuation devices and institutional change are key aspects of financialisation, but have been largely separated in the literature. This article explores causal link between both concepts. We draw on linked ecologies framework to argue that financialised valuation, such as market valuation assets liabilities, creates opportunities for financial experts influence policy processes. Making use thei...

In this note we give an algebraic proof of “deformation quantization” by making use of the theory of Unital Gröbner bases over a valuation ring. MSC: 16Z05,13P10 In this note we give an algebraic proof of deformation quantization (c.f. [7]). We do this be developing in (Sec. 1) the theory of unital Gröbner bases over a valuation ring. We then in (Sec. 2) obtain, almost immediately, our desired ...

This research explores the idea of inducing domain-specific semantic class taggers using only a domain-specific text collection and seed words. The learning process begins by inducing a classifier that only has access to contextual features, forcing it to generalize beyond the seeds. The contextual classifier then labels new instances, to expand and diversify the training set. Next, a cross-cat...

We study some factorization properties for univariate polynomials with coefficients in a discrete valuation domain (A, v). We use some properties of the Newton index of a polynomial F (X) = ∑d i=0 aiX d−i ∈ A[X] to deduce conditions on v(ai) that allow us to find some information on the degree of the factors of F .

We study participation in contests with heterogeneous agents. For the all-pay auction with multiple (identical) prizes where contestants belong to group H or L; valuations (for the prizes) are independently and, within groups, identically distributed, we provide a sufficient condition for all L contestants to drop-out – always choose zero effort. The drop-out is possible even if there is some c...

In some bargaining situations, agreement has implications for agents beyond the parties involved, and if so, delays in reaching an agreement or failing to reach an agreement, when this would be profitable, may imply significant welfare losses. The question raised in this paper is whether the intervention of a government, who has a positive valuation of agreement and therefore offers a subsidy, ...

1 Subadditive Valuations 1.1 The Setup In this lecture we study a scenario that generalizes almost all of the ones that we've studied in the course. • A set U of m non-identical items. As always, we also assume that every valuation satisfies v i (∅) = 0 and is monotone (i.e., S ⊆ T implies v i (S) ≤ v(T)). Subadditivity is yet another way to formalize the idea that items are not complements — t...

depiction of a solution space with several clusters Figure 2: Left: recursive counting by partitioning the solution space. Right: fragmentation of solution clusters. away the number of clusters in which x1 takes both values, 0 and 1. Thus, #clusters(F) = #clusters(F)|x1=0 + #clusters(F)|x1=1− #clusters(F)|x!=0&x1=1. The tricky part is to compute #clusters(F)|x1=v1 for any v1, as this no longer ...
