We advocate the use of absolute moment ratio statistics in conjunctionwith standard variance ratio statistics in order to disentangle lineardependence, non-linear dependence, and leptokurtosis in financial timeseries. Both statistics are computed for multiple return horizonssimultaneously, and...

The adoption of the International Monetary Fund (IMF) Structural Adjustment Programme (SAP) in 1986 resulted in the transition from fixed exchange rate regime to floating exchange rate regime in Nigeria. Ever since, the exchange rate of naira vis-à-vis the U.S dollar has attained varying rates...

The persistence properties of economic time series has been a primary object of investigation in a variety of guises since the early days of econometrics. This paper suggests investigating the persistence of processes conditioning on their history. In particular we suggest that examining the...

This research uses spectral methodology to study how the volatility of spot exchange rate misalignments changed as a result of (1) signing of the Plaza Accord and (2) introduction of the Euro. We study the deviations of Canadian Dollar/US Dollar, Japanese Yen/US Dollar and US Dollar/British...

This paper constructs an early warning system for currency crises in Nigeria based on selected key macroeconomic indicators. It estimates the probabilities of currency crises as a logistic function of the included variables within the framework of a logit model. Particularly, the extent to which...

A theory-consistent CVAR scenario describes a set of testable regularieties one should expect to see in the data if the basic assumptions of the theoretical model are empirically valid. Using this method, the paper demonstrates that all basic assumptions about the shock structure and...

We employ a threshold vector error correction model approach to investigate the impact of China's exchange rate marketization reform in August 2015 on the linkage between renminbi (RMB) onshore (CNY) and offshore (CNH) exchange rates and the impact of post-reform policy interventions by the...

There are no established benchmarks for evaluating currency investment manager performance. Some analysts have suggested that known investing styles like momentum, purchasing power parity, and carry serve as benchmarks. Challenges for this approach include: there is no market portfolio; there...

Asset prices undergo long swings that revolve around benchmark levels. In currency markets, fluctuations involve real exchange rates that are highly persistent and that move in near-parallel fashion with nominal rates. The inability to explain these two regularities with one model has been...

The paper summarizes the current theory of how a floating exchange rate is determined, dividing the subject into what determines the steady state and what determines the transition to steady state. The inadequacies of this model are examined, and an alternative quot;behavioralquot; model, which...
