Market Equilibrium with Transaction Costs
Identical products being sold at different prices in different locations is a
common phenomenon. Price differences might occur due to various reasons such as
shipping costs, trade restrictions and price discrimination. To model such
scenarios, we supplement the classical Fisher model of a market by introducing
{\em transaction costs}. For every buyer and every good , there is a
transaction cost of \cij; if the price of good is , then the cost to
the buyer {\em per unit} of is p_j + \cij. This allows the same good
to be sold at different (effective) prices to different buyers.
We provide a combinatorial algorithm that computes -approximate
equilibrium prices and allocations in
operations -
where is the number goods, is the number of buyers and is the sum
of the budgets of all the buyers
Tunnel splittings for one dimensional potential wells revisited
The WKB and instanton answers for the tunnel splitting of the ground state in
a symmetric double well potential are both reduced to an expression involving
only the functionals of the potential, without the need for solving any
auxilliary problems. This formula is applied to simple model problems. The
prefactor for the splitting in the text book by Landau and Lifshitz is amended
so as to apply to the ground and low lying excited states.Comment: Revtex; 1 ps figur
From Pronoun to Identity: Tracing the History of the Word Otaku
Words are vessels of power; the power to convey meaning. Words can give shape to the identity of a group, and the same word can stereotype one for generations. This research paper is about one such word – ‘Otaku’. The aim of this research paper is to trace the history of the term ‘otaku’, and understand how it evolved from a second person
pronoun to a term that identifies an entire subcultur
