The study was meant to evaluate the cost and revenue efficiency of the Zimbabwean banking sector during the period 2009-2014. The study employed the Data Envelopment Analysis and the Tobit Regression methods. The estimation of cost and revenue efficiency shows that revenue and cost efficiency increased during the period 2009-2012. This coincided with high positive growth rates and economic stability. Efficiency declined in 2013-14 as a result of government controls on banking sector pricing and general decline in economic activity.

The study empirically establishes the causal relationship between financial innovation and economic growth in SADC. Using an Autoregressive Distributed Lag (ARDL) Model, estimated by Pooled Mean Group and Dynamic Fixed Effects, the study finds that financial innovation has a positive relationship to economic growth in long run for SADC. The long run estimations, however, show existence of a weak relationship. Introducing a direct measure of financial innovation buttresses the role of financial innovation in growth in SADC.
Since the 2007 sub-prime financial crisis, world bank capital ratios have increased. In this paper, we investigate the impact of increased bank capital requirements introduced under the Basel Accord framework on the costs of intermediation. We attempt to answer this central question by running panel regressions using 2001 – 2012 annual bank-level data for ten banks constituting inter alia the four largest South African banks. We conclude that high capital requirements are associated with increased costs of intermediation.
Commodity terms of trade shocks have continued to drive macroeconomic uctuations in most emerging market economies. The volatility and persistence of these shocks have posed great challenges for monetary policy. This study employs a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model to evaluate the optimal monetary policy responses to commodity terms of trade shocks in commodity dependent emerging market economies. The model is calibrated to the South African economy.
Emerging market economies (EMEs) have persistently experienced different waves of commodity terms of trade disturbances, generating macroeconomic instabilities. The adoption of inflation targeting (IT) by many emerging market economies has raised the questions about its relative suitability in dealing with these shocks compared with other regimes. This paper tests the robustness of inflation targeting compared to monetary targeting and exchange rate targeting regimes in coping with commodity terms of trade shocks.
Most emerging market economies (EMEs) which have implemented inflation targeting (IT) have continued to experience large, frequent and sometimes persistent inflation target misses. At the same time these countries had reformed their institutional structures when implementing IT. In this paper we empirically study the importance of central bank independence, fiscal discipline and financial sector development for the achievement of inflation targets in EMEs using the panel ordered logit model.
This study investigates the link between bank concentration and interest rate pass-through (IRPT) in four sub-Saharan countries. It also analyses whether there is asymmetry in IRPT and whether such asymmetry is related to changes in bank concentration. By applying a number of econometric methods including Asymmetric Error Correction Models, Mean Adjustment Lag (MAL) models and Autoregressive Distributed Lag models on monthly data for the period 1994-2007, the study found some evidence of a relationship between bank concentration and IRPT in all four countries.
This paper studies the impacts of bank capital regulation on business cycle fluctuations. To do so, we adopt the Bernanke et al. (1999) "financial accelerator" model (BGG), to which we augment a banking sector to study the procyclical nature of Basel II claimed in the literature. We first study the impacts of a negative shock to entrepreneur's net worth and a positive monetary policy shock on business cycle fluctuations.
