The Long-run Economic Relationships: an Optimization Approach to Fractional Integrated and Bilinear Time Series
نویسندگان
چکیده
One objective of this paper is to estimate the parameters p,d,q of an autoregressive fractionally integrated moving average ARFIMA(p,d,q) stochastic model by minimizing the squares of the residuals using a Bayesian global optimization techniques. We consider bilinear model, too because it is the simple extension of linear model, defined by adding a bilinear term to traditional ARMA model. Therefore, the second objective of the paper is to estimate parameters of a bilinear time series.

A Nonlinear Model of Economic Data Related to the German Automobile Industry
Prediction of economic variables is a basic component not only for economic models, but also for many business decisions. But it is difficult to produce accurate predictions in times of economic crises, which cause nonlinear effects in the data. Such evidence appeared in the German automobile industry as a consequence of the financial crisis in 2008/09, which influenced exchange rates and a...

متن کاملImproving Long Run Marginal Cost based Pricing along with Extended Benefit Factor method for Revenue Reconciliation of Transmission Network in Restructured Power System
Abstract : There are several methods to cover the costs of a transmission system and distribution networks. These methods are divided into either incremental or marginal approaches, which can be either long-term or short-term. The main difference between the incremental and marginal approach is how to calculate the cost of using the network. In the incremental approach, simulation and in the ma...
متن کاملEffects of Trade and Financial Liberalizations on the Government Size: The Case of Iran
This paper tries to analyze effects of trade and financial liberalizations on the Iranâs government size during both long-run and short- run. Accordingly, a specification of the auto regression with distributed lag (ARDL) has been used for investigating the long run relationships between variables, and a vector correction model (VECM) has examined dynamically the short-run relationships betwe...
