We test the inertial properties of South African inflation in a Markov-Switching autoregressive fractionally integrated moving average model. This allows us to test for long memory and study the persistence of inflation in multiple regimes. We show that inflation is more volatile and persistent...

We try and detect whether there exists a threshold level of inflation for the US economy over 1801-2013, beyond which it has a negative effect on economic growth. We use a combination of nonparametric (NP) and instrumental variable semiparametric (SNP-IV) methods to obtain inflation thresholds...

We compare inflation forecasts of a vector fractionally integrated autoregressive moving average (VARFIMA) model against standard forecasting models. U.S. inflation forecasts improve when controlling for persistence and economic policy uncertainty (EPU). Importantly, the VARFIMA model,...

This paper studies the interplay of fiscal policy and asset price returns of the United States in a time-varying-parameter vector autoregressive model. Using annual data from 1890 to 2013, we study the effects of dynamic shocks to both fiscal policy and asset returns on asset returns and fiscal...

This paper analyses the extent to which the South African Reserve Bank (SARB) uses the repo rate in response to exchange rate depreciations. We use a Vector Autoregression to model the simultaneous linkage between the real effective exchange rate and the policy rate. A combination of short-run...

We compare nonlinear cointegration tests with the standard cointegration tests in studying the relationship of the Dow Jones Islamic finance index with three other conventional equity market indices. Our results show that there is a long-run nonlinear cointegrating relationship between the Dow...

We analyse the relationship between the South African real exchange rate and economic fundamentals - demand, supply and nominal shocks. Using a time-varying parameter VAR we study the coherence, conditional volatility and impulse responses of the exchange rate over specific periods and policy...

This study assesses how fiscal policy affects the dynamics of asset markets, using Bayesian vector autoregressive models. We use sign restrictions to identify government revenue and government spending shocks, while controlling for generic business cycle and monetary policy shocks. In addition...

The macroeconomic response to uncertainty for India is studied in a structural model that decomposes uncertainty into negative and positive contributions. The results show that uncertainty shocks reduce industrial production, lead to an exchange rate depreciation, lowers prices and increases...

We study the response of South African monetary policy decisions to foreign monetary policy shocks. We estimate the extent of foreign monetary policy pass-through by augmenting standard Taylor rules and comparing the results within the context of a Global New-Keynesian Dynamic Stochastic General...
