paradox, all exact science is dominated by the idea of approximation. Bertrand Russell (1872–1970) Most natural optimization problems, including those arising in important application areas, are NP-hard. Therefore, under the widely believed conjecture that P = NP, their exact solution is prohibitively time consuming. Charting the landscape of approximability of these problems, via polynomial time algorithms, therefore becomes a compelling subject of scientific inquiry in computer science and mathematics

44 West 4th Street, New York, NY 10012, USA b CEPR, London, UK Received 3 July 2002; accepted 13 June 2003 Abstract I examine the welfare properties of free entry under conditions of simultaneous entry. Specifically, I consider the second-best problem of in uencing the number of entrants while taking as given ÿrm behavior upon entry. I consider two alternative models of simultaneous entry: grab-the-dollar entry and war-of-attrition entry. I show that, if entry costs are low, then the results from

varying amounts of detail would need to be filled in. Problem 1.1: If r ∈ Q \ {0} and x ∈ R \ Q, prove that r + x, rx ∈ Q. Solution: We prove this by contradiction. Let r ∈ Q\{0}, and suppose that r +x ∈ Q. Then, using the field properties of both R and Q, we have x = (r + x) − r ∈ Q. Thus x ∈ Q implies r + x ∈ Q. Similarly, if rx ∈ Q, then x = (rx)/r ∈ Q. (Here, in addition to the field properties of R and Q, we use r = 0.) Thus x ∈ Q implies rx ∈ Q. Problem 1.2: Prove that there is no x ∈ Q such that x2
