Centerpoint Theorems for Wedges
The Centerpoint Theorem states that, for any set S of n points in R, there exists a point p in R such that every closed halfspace containing p contains at least dn/(d+ 1)e points of S. We consider generalizations of the Centerpoint Theorem in which halfspaces are replaced with wedges (cones) of angle α. In R, we give bounds that are tight for all values of α and give an O(n) time algorithm to f...
متن کاملGraduating to globalisation
In this paper we examine the relationship between firm characteristics and the decision of the firm to sell in the domestic market, export and/or invest abroad. We find that globalisation of Indian firms through the sharp increase in exports and foreign direct investment can be explained by firm characteristics. Data for a set of more than 1600 Indian firms for 10 years shows that exporting and...
متن کاملGraduating Mortality Rates via Divergences
One of the most important tasks in actuarial science is to describe the actual but unknown mortality pattern of a population. In order to achieve this, the actuary calculates from raw data the crude mortality rates, which usually form an irregular series. Because of this, it is common to revise the initial estimates with the aim of producing smoother estimates, with a procedure called graduatio...
متن کاملFloodlight illumination of infinite wedges
The floodlight illumination problem asks whether there exists a one-to-one placement of n floodlights illuminating infinite wedges of angles α1, . . . , αn at n sites p1, . . . , pn in a plane such that a given infinite wedge W of angle θ located at point q is completely illuminated by the floodlights. We prove that this problem is NP-hard, closing an open problem from 2001 [6]. In fact, we sho...
متن کاملWedges, and Capital Formation
This paper focuses on how inflation interacts with taxes and interest rates to affect capital formation.1 It uses a simple credit-market framework to explain how inflation magnifies the distorting effects of taxation when the tax treatment of interest income and expense is not fully indexed to inflation.2 The distortion involves a real tax wedge consisting of the difference between the real int...
