This paper exploits the Lucas’ (1973) signal extraction model to study the effect of uncertainty in the output-inflation trade-off on inflation, using a monetary model with asymmetric central bank preferences over inflation and output. We show that the implication of the uncertainty is...

This paper derives the econometric restrictions imposed by the Barro and Gordon (1983) model of dynamic time inconsistency on a bivariate time-series model of Consumer Price Index (CPI) inflation and real Gross Domestic Product (GDP), and tests these restrictions based on quarterly data for...

This paper estimates the Bayesian dynamic stochastic general equilibrium (DSGE) model and uses the model to account for the short-run monetary policy response to increased aid inflows in Malawi. The estimates reveal that the monetary authorities reacted to increased foreign aid inflows the same...

The real interest rate is a very important variable in the transmission of monetary policy. It features in vast majority of financial and macroeconomic models. Though the theoretical importance of the real interest rate has generated a sizable literature that examines its long-run properties,...

This paper examines the causal relationship between economic policy uncertainty (EPU) and equity market uncertainty (EMU) in the US using linear and nonlinear Granger causality tests. We use daily data on the newly developed indexes by Baker et al. (2013) covering 1985:01:01 to 2013:06:14....

Consumption and output responses to fiscal shocks are studied in a model with fiscal foresight. Fiscal foresight reduces both output multipliers and consumption. However, key features such as sticky wages, credit constrained households and elastic labour supply, are able to generate both...

This study assesses debt sustainability in South Africa allowing for possible nonlinearities in the form of threshold behaviour by fiscal authorities. A long historical data series on the debtto- GDP ratio and models with fixed and time-varying thresholds allowing the level of debt to vary...

The double dividend hypothesis contends that environmental taxes have the potential to yield multiple benefits for the economy. However, empirical evidence of the potential impacts of environmental taxation in developing countries is still limited. This paper seeks to contribute to the...

This paper is the first one to analyse the effect of aggregate government spending and taxes on output for South Africa using three types of a calibrated DSGE model and more data driven models such as a structural vector error correction (SVEC) model and a time-varying parameter VAR (TVP-VAR) to...

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...
