In this paper a simultaneous-equations model of firm closing and wage determination is developed in order to analyse how wages adjust to unfavorable shocks that raise the risk of displacement through firm closing, and to what extent a wage change affects the exit likelihood. The results show that the fear of job loss generates bargaining concessions instead of compensating differentials. A nove...

This paper studies majority voting over the size and location of a public good when voters di¤er both in income and in their preferences for the public good location. Public good provision is …nanced either by a lump sum tax or by a proportional income tax. We analyze both the simultaneous and the sequential determinations of the public good’s size and location. We show that, while the choice o...

Recently we have had occasion to make a considerable number of determinations of fibrin by the method of Cullen and Van Slyke, which we have modified slightly (1). Simultaneous determinations were made by precipitating fibrinogen with 10.6 per cent sodium sulfate at 37°C and some determinations by the methods of Gram (2) and of Foster and Whipple (3). The fundamental procedures of various recen...

Here we report the spectral characteristics of the high and low states of the pulsar 4U 0114+65 and examine the change in the parameters of the spectral model. A power law and a photoelec-tric absorption by material along the line of sight together with a high energy cutoff suffice to describe the continuum spectrum in both the states. A fluorescence iron line at ∼6.4 keV is present in the high...

We investigate the problem of verifying location claims of mobile devices, and propose a new property called simultaneous distance modification (SDM). In localization protocols satisfying the SDM property, a malicious device can lie about its distance from the verifiers, but all distances can only be altered by the same amount. We demonstrate that the SDM property guarantees secure verification...
