This paper investigates the relationship between natural gas consumption, price, crude oil Foreign direct Investment and per capita GDP in Nigeria to ascertain their causal effects dependencies by using time series data from 1990 2020 an econometric platform Vector Error Correction model (VECM). The result of VECM estimate, Granger causality test Variance decomposition all suggest presence a st...

We consider structural vector error correction models (VECMs) in which permanent shocks are partially identified with a set of long-run restrictions, and fully identified with an additional set of short-run restrictions. An identification method with a combination of short-run and long-run restrictions has been studied in the vector autoregressive models literature, but not thoroughly applied t...

This paper discusses the money demand function in China. We use Cointegration technique and Error Correction Model to estimate the long-run and short -run money demand function. We find that M2 aggregate appears to be cointegrated with price level and income. We also specified a satisfying error correction model for M2.

The Vector Autoregressive (VAR) model, the Error Correction Model (ECM), and the Kalman Filter Model (KFM) are used to forecast UK stock prices. The forecasting performance of the three models is compared using out of sample forecasting. The results show that the forecasting performance of the ECM is better than that of the VAR and the KFM, and that the VAR performs a forecasting better than th...

I make a rough estimate of the accuracy threshold for fault tolerant quantum computing with concatenated codes. First I consider only gate errors and use the depolarizing channel error model. I will follow P.Shor [1] for fault tolerant error correction (FTEC) and the fault tolerant implementation of elementary operations on states encoded by the 7-qubit code. A simple computer simulation sugges...

We develop methods for Bayesian inference in vector error correction models which are subject to a variety of switches in regime (e.g. Markov switches in regime or structural breaks). An important aspect of our approach is that we allow both the cointegrating vectors and the number of cointegrating relationships to change when the regime changes. We show how Bayesian model averaging or model se...

Over the past three decades vertical price transmission analysis has been the subject of considerable attention in applied agricultural conomics. It has been argued that the existence of asymmetric price transmission generates rents for marketing and processing agents. Retail prices allegedly move faster upwards than downwards in response to farm level pricemovements. This is an important issue...
