This paper analyses the descriptive power of the different extensions of the Taylor rule. It also investigates whether monetary policy in South Africa can indeed be described by a linear Taylor rule or, instead, by a nonlinear rule. In particular, we extend the linear Taylor rule to a...

Much interest has been paid recently to the nonlinear cointegrating relations existing among economic variables. Various testing procedures are already available to test for the existence of nonlinear cointegration. For example, Breitung (2001) proposes rank tests and his testing procedure has...

Several governments in sub-Saharan Africa have embarked on various market reforms to improve commodity market performance. However, the success of such market reforms depends partly on the strength of the transmission of price signals between spatially separated markets and between different...

The objective of this paper is to examine the government revenue and expenditure relationship in the context of what is known as the soft and hard budget constraint strategy. We adopt a nonlinear framework with structural breaks and focus our empirical analysis in three countries. Two of them...

Price and liquidity puzzles have been identified as two major counterintuitive findings arising from monetary shocks. We investigate their presence in eleven African countries, using a dynamic stochastic general equilibrium model designed for indebted small open-economies. Our simulations reveal...
