This paper attempts to investigate the time-varying causal dynamics between China's money and output by using a Markov switching causality approach. Unlike the pre-specified break points and rolling-window methods, the Markov switching causality approach can capture the time-varying causality...

Tests of social support theory have relied on aggregate crime rates as the outcome of interest, but such a focus ignores the potentially important macro-level processes and effects on individual-level behavior We thus perform the first multi-level investigation of social support theory.

The Consumer Sentiment Index (CSI), a leading macroeconomic indicator, reflects consumers' assessments of current financial situations, forecasts consumers' buying behavior, and allows business organizations, such as banks, to capture business opportunities. There is a consensus that the trend...

Using a combination of analytical and numerical methods, the global bifurcations and chaotic dynamics of two non-linearly coupled parametrically excited van der Pol oscillators are investigated in detail. With the aid of the method of multiple scales, the slow flow equations are obtained. Based...
