This paper presents testing procedures for comparison of misspeci…ed calibrated models. The proposed tests are of the Vuong-type (Vuong, 1989; Rivers and Vuong, 2002). In our framework, an econometrician selects values for the parameters in order to match some characteristics of the data with those implied by the competing theoretical models. We assume that(More)
A quantitative description of specific ion effects is an essential and focused topic in colloidal and biological science. In this work, the dynamic light scattering technique was employed to study the aggregation kinetics of colloidal particles in the various alkali ion solutions with a wide range of concentrations. It indicated that the activation energies(More)

We demonstrate theoretically and empirically that strategic considerations are important in shaping cash policies of innovative firms. In our model, firms decide whether to invest in innovation while facing uncertainty regarding the structure of ensuing product markets. Cash holdings reduce innovative firms’ dependence on external financing and, therefore,(More)
A novel method based on particle filter has been proposed for Rayleigh channel state estimate and tracking in this paper. After receiving a symbol, the particles approximate the channel state at a higher temperature and a sequential resampling is taken to generate the initial particles for the lower temperature particle filter . With this simulated(More)
