How Much Does Violence Tax Trade?, S. Brock Blomberg, Gregory Hess
How Much Does Violence Tax Trade?, S. Brock Blomberg, Gregory Hess
CMC Faculty Publications and Research
We investigate the empirical effect of violence, as compared to other trade impediments, on trade flows. Our analysis is based on a panel data set with annual observations on 177 countries from 1968 to 1999, which brings together information from the Rose data set, the iterate data set for terrorist events, and data sets of external and internal conflict. We explore these data with traditional and theoretical gravity models. We calculate that, for a given country year, the presence of terrorism together with internal and external conflict is equivalent to as much as a 30% tariff on trade. This is …
Quadratic Forms And Height Functions, Lenny Fukshansky
Quadratic Forms And Height Functions, Lenny Fukshansky
CMC Faculty Publications and Research
The effective study of quadratic forms originated with a paper of Cassels in 1955, in which he proved that if an integral quadratic form is isotropic, then it has non-trivial zeros of bounded height. Here height stands for a certain measure of arithmetic complexity, which we will make precise. This theorem has since been generalized and extended in a number of different ways. We will discuss some of such generalizations for quadratic spaces over a fixed number field as well as over the field of algebraic numbers. Specifically, let K be either a number field or its algebraic closure, and …
The (No) Work And (No) Leisure World Of Women In Assi, Banaras, Nita Kumar
The (No) Work And (No) Leisure World Of Women In Assi, Banaras, Nita Kumar
CMC Faculty Publications and Research
In the riverside neighborhood (mohalla) of Assi, in the south of Banaras, families of the following professions are to be found: the preparation and retail of foods such as: milk, sweets, tea, paan, peanuts and snacks; clerical work in offices or shops; private professional work, such as priesthood, teaching, boating, cleaning toilets; and crafts, such as masonry, weaving, making and maintaining jacquard machines, carpentry, and goldsmithy. All this work is done by men in the public sphere. In Banaras, the observable and articulated sphere of activity called "work" (kam) largely exists for men only. Men are …
Siegel’S Lemma With Additional Conditions, Lenny Fukshansky
Siegel’S Lemma With Additional Conditions, Lenny Fukshansky
CMC Faculty Publications and Research
Let K be a number field, and let W be a subspace of K-N, N >= 1. Let V-1,..., V-M be subspaces of KN of dimension less than dimension of W. We prove the existence of a point of small height in W\boolean OR(M)(i=1) V-i, providing an explicit upper bound on the height of such a point in terms of heights of W and V-1,..., V-M. Our main tool is a counting estimate we prove for the number of points of a subspace of K-N inside of an adelic cube. As corollaries to our main result we derive an explicit …
Integral Points Of Small Height Outside Of A Hypersurface, Lenny Fukshansky
Integral Points Of Small Height Outside Of A Hypersurface, Lenny Fukshansky
CMC Faculty Publications and Research
Let F be a non-zero polynomial with integer coefficients in N variables of degree M. We prove the existence of an integral point of small height at which F does not vanish. Our basic bound depends on N and M only. We separately investigate the case when F is decomposable into a product of linear forms, and provide a more sophisticated bound. We also relate this problem to a certain extension of Siegel’s Lemma as well as to Faltings’ version of it. Finally we exhibit an application of our results to a discrete version of the Tarski plank problem.
