This paper uses newly available firm-level tax data to evaluate the market structure in South African manufacturing sectors in the period 2010.12. To describe the market structure we compute markups for South African manufacturing firms and concentration indexes for 4-digit manufacturing sectors. We find both significant markups and significant concentration across most sectors.We compare computed markups and concentration with early estimates in South Africa and with other international benchma...

The primary objective of this paper is to investigate the impact of moral hazard on the effectiveness of deposit insurance in achieving banking stability. If moral hazard explains banking instability arising from the adoption of deposit insurance, then deposit insurance will be associated with bank insolvency more than with bank runs. To test the hypothesis, we develop a new empirical framework distinguishing between banking instability initiated by panic withdrawals of deposits, and banking ins...

This paper investigates the evolution of monetary transmission mechanism in Malawi between 1981 and 2010 using a time varying parameter vector autoregressive (TVP-VAR) model with stochastic volatility. We evaluate how the responses of real output and general price level to bank rate, exchange rate and credit shocks have changed over time since Malawi adopted financial reforms in 1980s. It is becoming clear from literature that financial reforms can change the monetary transmission by changing th...

Funding constraints experienced by Sub-Saharan African (SSA) countries has led to reliance on foreign direct investment (FDI) and foreign aid as alternative sources of finance. Despite the importance of FDI for growth, SSA has failed to attract an increasing share of global FDI and at the same time faces volatile aid flows. This study examines the role of foreign aid in enhancing FDI inflows to 31 SSA countries for the period 1995 to 2012. Using panel data estimation techniques, the results sugg...

Funding constraints experienced by sub-Saharan Africa (SSA) countries have led to reliance on foreign direct investment (FDI) and foreign aid as alternative sources of finance. Despite the importance of FDI for growth and development, SSA’s share in global FDI inflows trails that of other developing regions. This study examines the role of foreign aid in enhancing FDI inflows to 31 SSA countries from 1995-2012. Using multilevel analysis, the results suggest that productive infrastructure aid is ...

The foreign aid arena as it pertains to the African continent has traditionally been dominated by the Organization of Economic Co-operation and Development (OECD) countries, however over the last three decades non-traditional donors such as the China, South Africa and Brazil have emerged in the donor field. The increasing importance of non-traditional donors has meant that the economic and political stronghold of Western and OECD countries in sub-Sahara African (SSA) has gradually ebbed, due to ...

The literature on determinants of cross-border capital flows has consistently assumed the determinants of such flows to be constant throughout the sample. This paper investigates this notion by estimating the time varying relationship between portfolio flows to South Africa and two widely accepted determinants of such flows: the sovereign spread and global risk (measured by the CBOE Volatility Index, henceforth VIX). The results show that the time variation is highly significant and a constant p...

The paper presents a two-country real business cycle model with a financial sector that intermediates portfolio flows. It is changes in demand for financial assets from foreign investors relative to domestic investors that gives rise to portfolio flows. The simulations show that portfolio flows to emerging markets respond negatively to global risk in line with findings from the empirical literature. The transmission channel that links portfolio flows to credit in emerging markets is the financia...
