In this paper, based on the generalized Jacobi elliptic function expansion method,we obtain abundant new complex doubly periodic solutions of the double Sine-Gordon equation (DSGE), which are degenerated to solitary wave solutions and triangle function solutions in the limit cases,showing that this new method is more powerful to seek exact solutions of nonlinear partial differential equations i...

This paper estimates fiscal policy multipliers for small states using two distinct models: an empirical forecast error model with data from twenty-three across the world, and a dynamic stochastic general equilibrium (DSGE) calibrated to hypothetical state’s economy. We find that, in short term, government consumption investment are both about 0.4, on average, DSGE baseline results, they affecte...
