The quantal response equilibrium (QRE) notion of Richard D. McKelvey and Thomas R. Palfrey (1995) has recently attracted considerable attention, due in part to its widely documented ability to rationalize observed behavior in games played by experimental subjects. However, even with strong a priori restrictions on unobservables, QRE imposes no falsifiable restrictions: it can rationalize any di...

Traditional methods have relied on classification based on morphology and enzymatic tests, which are subjective and can be time-consuming (typical turnaround from sample collection to results is measured in weeks). Recently, it has been demonstrated that the fatty acids of the cell walls of these bacteria are diagnostic for some species (1). These fatty acids are mainly comprised of high molecu...

This paper presents the results of a policy oriented macroeconomic experiment involving an ‘international’ economy with a relatively small ‘home’ country and a large ‘foreign’ country. It compares the economic performance of two alternative tax systems as a means to finance unemployment benefits: a wage tax system versus a sales-tax-cum-labor-subsidy system. The two systems are applied to the s...

Mispricing (the difference between prices and their underlying fundamental values) is an important characteristic of markets. The literature on the topic consists of many different measures. This state of affairs is unsatisfactory, since different measures may produce different results. Stöckl et al. (2010) partially address this problem by proposing (among other things) that measures of mispri...

Opalized white tuff (OWT) with 40 μm average particle size and 39.3 m(2)/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi). The cure characteristic, apparent activation energy of cross-link (E(ac)) and reversion (E(ar)), and mechanical properties of a variety of composites ...

This paper investigates the robustness of the “two-tiered labor market” experimental results of Brown, Falk and Fehr (2004) by subjecting relationships to stochastic interruptions. Using two different subject pools, we first replicate the basic pattern of high quality private contracting and low quality public contracting. We then study the impact of exogenous random ‘downturns’ in which firms ...

In this paper we present benchmark results from the parallel implementation of the three{dimensional Navier{Stokes solver Prism on diierent parallel platforms of current interest: IBM SP2 (all three types of processors), SGI Power Challenge XL and Cray C90. The numerical method is based on mixed spectral element{ Fourier expansions in (x ? y) and z?directions, respectively. Each (or a group) of...

Altruism in Society: Evidence from a Natural Experiment Involving Commuters We study social preferences in the form of altruism using data on 959 interactions between random commuters at selected traffic intersections in the city of Brisbane, Australia. By observing real decisions of individual commuters on whether to stop (give way) for others, we find evidence of (i) gender discrimination by ...

Preferences for Redistribution and Pensions: What Can We Learn from Experiments? Redistribution is an inevitable feature of collective pension schemes and economic experiments have revealed that most people have a preference for redistribution that is not merely inspired by self-interest. Interestingly, little is known on how these preferences interact with preferences for different pension sch...

Gender, Economic Development and Islam: A Perspective from France Muslims do less well on the French labor market than their non Muslim counterparts. One explanation for this relative failure can be characterized by the following syllogism: (1) the empowerment of women is a sine qua non for economic progress; (2) in-group norms among Muslims do not empower women; and hence (3) Muslim communitie...
