MONETARY EXCHANGE RATE MODEL REVISITED: COINTEGRATION AND FORECASTING IN HETEROGENEOUS PANEL DATA
ABSTRACT This study re-examines the exchange rate-monetary fundamentals link with in a panel data framework. Pure time series and pooled time series-based tests fail to find empirical support for monetary exchange rate models (Sarantis (1994) and Groen (2000)). Using recently developed Panel Data Techniques; we would test the exchange rates and monetary fundamentals in a quarterly panel of 19 countries mostly from developed region extending from 1973.1 to 1997.1. Present analysis would be centered on three issues. First, we test whether exchange rates cointegrated with long run determinants predicted by economic theory. For this purpose, we would be employed Pedroni (1997) and Larsson et al (2001) panel cointegration tests for empirical validation of the study. Second, we will also test the short run implications of exchange rate model. These short run implications will be tested; through adapting the panel VEC model the short run identification schemes of Johansen and Juselius (1994). The last issue is to examine the ability for monetary fundamentals to forecast future exchange rate returns. The present endeavor will follow Mark and Sul (2001) approach for forecasting in the case of Panel Data Testing.Panel cointegration; Prediction; Exchange rates.
The Long-run Relationship between Real Exchange Rate and Real Interest Rate in Asian Countries: An Application of Panel Cointegration
The role of exchange rate policy in economic development has been the subject of much debate and controversy in the development literature. Interest rates and exchange rates are usually viewed as important in the transmission of monetary impulses to the real economy. In the short run the standard view of academics and policy-makers is that a monetary expansion lowers the interest rate and rises the exchange rate, with these price changes then affecting the level and composition of aggregate demand. Frequently, these influences are described as the liquidity effects of monetary expansion, viewed as the joint effect of providing larger quantities of money to the private sector. Popular theories of exchange-rate determination also predict a link between real exchange rates and real interest rate differentials. These theories combine the uncovered interest parity relationship with the assumption that the real exchange rate deviates from its long-run level only temporarily. Under these assumptions, shocks to the real exchange rate—which are often viewed as caused by shocks to monetary policy—are expected to reverse themselves over time. This study investigates the long-run relationship between real exchange rates and real interest rate differentials using recently developed panel cointegration technique. Although this kind of relationship has been studied by a number of researchers,1 very little evidence in support of the relationship has been reported in the case of developing countries.
Money-income Link in Developing Countries: a Heterogeneous Dynamic Panel Data Approach
The question whether real money causes real output appears to
be important for many economists working in the area of macroeconomics
and, has been subjected to a variety of modern econometric techniques,
producing conflicting results. One often applied method to investigate
the empirical relationship between money and real activity is Granger
causality analysis [Granger (1969)]. Using this approach, the causality
question can be sharply posed as whether past values of money help to
predict current values of output. This concept, however, should be
clearly distinguished from any richer philosophical notion of causality
[cf. Holland (1986)]. Present paper examines the relationship between
money (both M1 and M2) and income (Real GDP) for 15 developing countries
using a newly developed heterogeneous dynamic panel data approach.1 Sims
(1972) postulated “the hypothesis that causality is unidirectional from
money to income agrees with the post war U.S. data, whereas the
hypothesis that causality is unidirectional from income to money is
rejected”. Since then a voluminous literature has emerged testing the
direction of causality.2 Some studies have tested the relationship
between these variables and the direction of causality for a particular
country using time series techniques [e.g., Hsiao (1979) for Canada,
Stock and Watson (1989) for U.S. data, Friedman and Kuttner (1992, 1993)
for U.S. data, Thoma (1994) for U.S. data, Christiana and Ljungquist
(1988) for U.S. data, Davis and Tanner (1997) for U.S. data, Jusoh
(1986) for Malaysia, Zubaidi, et al. (1996) for Malaysia, Biswas and
Saunders (1998) for India, and Bengali, et al. (1999) for Pakistan].
Other studies have tested the above on a number of countries, for
example Krol and Ohanian (1990) used the data for Canada, Germany, Japan
and the U.K. Hayo (1999) using data from 14 European Union (EU)
countries plus Canada, Japan, and the United States. More recently Hafer
and Kutan (2002) used a sample of 20 industrialised and developing
countries. This paper contributes to this later strand of the
literature, which it extends in three directions. First, it employed a
newly developed panel cointegration technique [Larsson, et al. (2001)],
to examine the long-run relationship between money and income. Second,
the study performs panel causality test, recently developed by Hurlin
and Venet (2001), to explore the direction of causality between the said
variables. Third, the important contribution of the present study is to
test whether relationship between money and income is homogeneous or
heterogeneous across countries
Investigation of Cloud Scheduling Algorithms for Resource Utilization Using CloudSim
Compute Cloud comprises a distributed set of High-Performance Computing (HPC) machines to stipulate on-demand computing services to remote users over the internet. Clouds are capable enough to provide an optimal solution to address the ever-increasing computation and storage demands of large scientific HPC applications. To attain good computing performances, mapping of Cloud jobs to the compute resources is a very crucial process. Currently we can say that several efficient Cloud scheduling heuristics are available, however, selecting an appropriate scheduler for the given environment (i.e., jobs and machines heterogeneity) and scheduling objectives (such as minimized makespan, higher throughput, increased resource utilization, load balanced mapping, etc.) is still a difficult task. In this paper, we consider ten important scheduling heuristics (i.e., opportunistic load balancing algorithm, proactive simulation-based scheduling and load balancing, proactive simulation-based scheduling and enhanced load balancing, minimum completion time, Min-Min, load balance improved Min-Min, Max-Min, resource-aware scheduling algorithm, task-aware scheduling algorithm, and Sufferage) to perform an extensive empirical study to insight the scheduling mechanisms and the attainment of the major scheduling objectives. This study assumes that the Cloud job pool consists of a collection of independent and compute-intensive tasks that are statically scheduled to minimize the total execution time of a workload. The experiments are performed using two synthetic and one benchmark GoCJ workloads on a renowned Cloud simulator CloudSim. This empirical study presents a detailed analysis and insights into the circumstances requiring a load balanced scheduling mechanism to improve overall execution performance in terms of makespan, throughput, and resource utilization. The outcomes have revealed that the Sufferage and task-aware scheduling algorithm produce minimum makespan for the Cloud jobs. However, these two scheduling heuristics are not efficient enough to exploit the full computing capabilities of Cloud virtual machines
