Monetary policy-makers face a difficult task when evaluating the current state of the economy and deciding what actions are needed to achieve their objectives, such as keeping inflation within a given range. Because long and variable lags exist between a monetary policy action and its effects on economic variables, policy-makers need a way to assess whether their actions are having, or indeed w...

This paper investigates market integration and asymmetric price transmission in the world rice export markets. Using monthly rice prices from Thailand, Vietnam, and United States, we employ the Johansen test and estimate the threshold vector error correction model (TVECM). Our main findings are that export prices in the three countries are cointegrated, with Thailand and the United States the p...

In pursuit to sketch the Pakistan USA Exchange Rate patterns for the duration of 1991M3 to 2010M5 using the CHEERS model, the role of Goods Market and Financial Market is implied through the Purchasing Power Parity (PPP) and Uncovered Interest Parity (UIP) respectively. The results using Vector Error Correction Model (VECM) revealed that both Parities work in combination with near unity elastic...

Q uantum computers offer the prospect of computation that scales exponentially with data size. Unfortunately, a single bit error can corrupt an exponential amount of data. Quantum mechanics can seem more suited to science fiction than system engineering, yet small quantum devices of 5 to 7 bits have nevertheless been built in the laboratory, 100-bit devices are on the drawing table now, and eme...

We analyze the problem of a quantum computer in a correlated environment protected from decoherence by quantum error correction using a perturbative renormalization group approach. The scaling equation obtained reflects the competition between the dimension of the computer and the scaling dimension of the correlations. For an irrelevant flow, the error probability is reduced to a stochastic for...

in this article, we estimate the vertical price transmission through the iranian rice marketing chain by usingmonthly data from march 2000 to february, 2009 and error correction model (ecm).the causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. inproducer-retail and wholesale-retail models, price transmission is asymmetric but i...

the purpose of this study is to examine the dynamic effects of some macroeconomic variables: money stock, gross domestic product, consumer price index and exchange rates on determining housing price index behavior in iran using the error correction model. using seasonal data, the model is estimated by johansen-juselius cointegration approach during 1990-2007. the results reveal that all variabl...

In this paper, we construct an adaptive ARQ/HARQ scheme using RS code for error correction and CRC code for error detection (when working in pure ARQ). Scheme performance parameter is defined and investigated to find optimal threshold values. Simulations are performed in LMS channel.

The Laplace approximation is applied to measurement error models when the likelihood function involves high dimensional integrals. The cases considered are generalized linear models with multiple covariates measured with error and generalized linear mixed models with measurement error in the covariates. The asymptotic order of the approximation and the asymptotic properties of the Laplace-based...
