Visual perception can be modulated by sounds. A drastic example of this is the sound-induced flash illusion: when a single flash is accompanied by two bleeps, it is sometimes perceived in an illusory fashion as two consecutive flashes. However, there are strong individual differences in proneness to this illusion. Some participants experience the illusion on almost every trial, whereas others a...

Visua l illusion is the fallacious percep ti on of rea lity or some ac t ua lly existi ng object. In t his paper , we imit at e the mechanism of Ehrenst ein illusion, neon color sp readi ng illnsion , wa te r­ color illusion, Kanizsa illusion, shifted edg es illusion , and hybrid image illusion using t he O pen Source Comput er Vision Library (OpenCV). We also im itate th ese illusions using Ce...

This paper examines under what conditions fiscal policy in the form of government spending should contribute to macroeconomic stabilisation. To this end optimal fiscal targeting rules minimising the microfounded social loss are examined in the following settings. Firstly, for the benchmark New Keynesian model, where monetary policy is unconstrained, a neutrality result for fiscal obtains: fisca...

Abstract T his paper is to convince the usage of the nonlinear unit root tests when dealing with a nonlinear model. To do so, the stationary test for variables in a model titles “Fiscal Reaction Function in Iran” has been applied according to both the ordinary and the Nonlinear Dickey-Fuller (NDF) tests. Results show that while variables under investigation are stationary ...

The scintillating grid illusion refers to an illusory perception of black spots on the luminance increments at the intersections of gray grids on a black background. In this study, we examined how the shape of luminance increments modulated the strength of the illusion. In Experiment 1, we concurrently controlled the size and shape of luminance increments, and found significant reduction of the...

Japan is the world‘s third largest economy. But currently economic situations of Japan are not stable. It is not increasing as expected. Since 2013 it was world second largest economy but Japan loosed its placed to China in 2014 due to slow growth of important economic indicators. By using the basic Keynesian model, we will provide a detailed analysis of the short and long run impacts of the ch...
