We present a model where producers of complementary goods have the option to practice mixed bundling. In the first stage of a two-stage game, firms choose between a mixed bundling and a non-bundling strategy. In the second stage, firms choose prices. We show that mixed bundling is a dominant strategy for both firms. However, when the composite goods are not very close substitutes, at the bundli...

We present a novel approach to parsing phrase grammars based on Eric Brill's notion of rule sequences. The basic framework we describe has somewhat less power than a finite-state machine, and yet achieves high accuracy on standard phrase parsing tasks. The rule language is simple, which makes it easy to write rules. Further, this simplicity enables the automatic acquisition of phraseparsing rul...

We conjecture that the thought processes used to solve dominant strategy games and mixed strategy games are quite distinct. Two-person games with dominant strategies can be treated as simple decision problems that involve no assessment of one’s partner. By contrast, two-person games with mixed strategies require that one think about one’s partner. We measure differences in electroencephalogram ...

We study whether we can weaken the conditions given in Reny [4] and still obtain existence of pure strategy Nash equilibria in quasiconcave normal form games, or, at least, existence of pure strategy ε−equilibria for all ε > 0. We show by examples that there are: 1. quasiconcave, payoff secure games without pure strategy ε−equilibria for small enough ε > 0 (and hence, without pure strategy Nash...

changes in credit risk may arise when either the value or the risk of corporate assets changes. changes in the equity value associated with the changes in the asset value and changes in asset risk can be characterized into potentially countervailing direct and indirect effects. the indirect effect of risk on equity value is a function of factors that affect the debt value of including leverage,...

We investigate whether replicator dynamics justify “survival of the fittest” when players inherit pure strategies, mixed strategies, or rules for choosing strategies. A strategy that never is a best reply can survive replicator dynamics if only pure strategies are heritable, but only rationalizable strategies survive if mixed strategies are heritable. Now suppose agents can inherit the rule of ...

A new low-cost test method for analog integrated circuits, called the oscillation test, is presented. During the test mode, the circuit under test (CUT) is converted to a circuit that oscillates. Faults in the CUT which deviate the oscillation frequency from its tolerance band can be detected. Using this test method, no test vector is required to be applied. Therefore, the test vector generatio...

Broadcasting is a very effective technique to disseminate information to a massive number of clients when the data size is small. However, if the data size is large, the broadcast cycle may be long, and hence the access delay becomes a problem. Caching frequently accessed data at the client side can reduce the access latency and improve the bandwidth utilization. However, caching techniques may...

Mixed-mating systems, in which hermaphrodites can either self-fertilize or outcross, are common in many species of plants and invertebrates and have been informative models for studying the selective forces that can maintain both inbreeding and outbreeding in populations. Here, we document a remarkable instance of evolutionary convergence to an analogous mixed mating system by a vertebrate, the...
