This study evaluates the economic impact of the proposed COMESA-SADC-EAC Tripartite Free Trade Area (TFTA) on 26 African countries. It uses the global trade analysis project (GTAP) computable general equilibrium (CGE) model and database to measure the static effects of the establishment of the...

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...

International aid has an ambiguous effect on the macro-economy of the recipient country. To the extent that aid raises consumer expenditure, there will be some real exchange rate appreciation and a shift of resources away from traded goods production and into non-traded goods production....

This paper develops a straightforward theoretical framework for evaluating exchange rate regime choice for small economies. It proposes that a floating exchange rate minimises national income and employment variation when real macroeconomic shocks predominate, whereas a pegged exchange rate...

This paper uses the cointegrated vector autoregressive (CVAR) model to assess the dynamic relationship between foreign aid inflows, public expenditure, revenue and domestic borrowing in Ethiopia. It departs from the existing literature by using a unique quarterly fiscal dataset (1993-2008) and...

The link between foreign aid and economic growth remains a controversial issue in the literature, and a large share of the disagreement could be explained by differences in the data employed. Using GDP data from three different versions of the Penn World Table and the World Development...

The paper examines Granger-causality between the producers' and the consumers' price using Australian data within the frequency domain framework. For long run relation, the Johansen and Juselius (1990) maximum likelihood approach to cointegration was utilized. The test is also supplemented by...

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...
