In this paper, we apply first and higher-order Euler discretizations to compare dynamic systems in discrete and continuous time. In addition, we stress the difference between backward and forward-looking approximations. Focussing on local bifurcations, we find that time representation is neutral and asymptotically neutral for models with saddle-node and Hopf bifurcations, respectively. Converse...

The polarized lepton pair forward–backward asymmetries in B → ρl+l− decay using a general, model independent form of the effective Hamiltonian is studied. The general expression for nine double–polarization forward–backward asymmetries are calculated. The study of the forward–backward asymmetries of the doubly–polarized lepton pair proves to be very useful tool in looking for new physics beyond...

Sentiment Analysis deals with consumer reviews available on blogs, discussion forums, E-commerce websites, and App Store. These online about products are also becoming essential for consumers companies as well. Consumers rely these to make their decisions very interested in judge services. a precious source of information requirement engineers. But not satisfied the overall sentiment; they like...

This study investigates the nature of price expectations in a competitive market. The approach is illustrated in an application to the U.S. pork market, which exhibits cyclical patterns and biological production lags. Pork price equations are estimated under different expectation regimes. The empirical results suggest the presence of heterogeneous price expectations among market participants. A...

In a standard overlapping generations model, active monetary policy reinforces mechanisms that lead to equilibrium indeterminacy and to countercyclical behavior of young-age consumption. The policy rule which minimizes inflation volatility can be active or passive, depending on the characteristics of shocks and the risk aversion of households. Inflation forecast errors are always greater under ...

Hybrid New Keynesian Phillips curve (NKPC) has been widely used in monetary policy literature (e.g. Gali and Gertler, 1999) as it contains both forward-looking and backward-looking components and therefore fits the data well. A typical backward-looking part of price setting behavior assumes that firms use the previous period’s price. In this paper, we propose a generalized version of the hybrid...

‎In this paper‎, ‎we use a complete pivoting strategy to compute the IUL preconditioner obtained as the by-product of the Backward Factored APproximate INVerse process‎. ‎This pivoting is based on the complete pivoting strategy of the Backward IJK version of Gaussian Elimination process‎. ‎There is a parameter $alpha$ to control the complete pivoting process‎. ‎We have studied the effect of dif...
