  • Measuring the determinants of educational spending in Africa 
    Akanbi, Olusegun Ayodele; Schoeman, N.J. (Nicolaas Johannes) (University of Pretoria, Department of Economics, 2007-05)
    This paper reports on research aimed at measuring the determinants of education spending in Africa and secondly, investigates whether expenditure on education in Africa optimizes social welfare. The empirical estimations ...
  • Measuring the welfare cost of inflation in South Africa : a reconsideration 
    Gupta, Rangan; Uwilingiye, Josine (University of Pretoria, Department of Economics, 2008-06)
    In this paper, using the Fisher and Seater (1993) long-horizon approach, we estimate the long-run equilibrium relationship between money balance as a ratio of income and the Treasury bill rate for South Africa over the ...
  • Misalignment in the growth-maximizing policies under alternative assumptions of tax evasion 
    Gupta, Rangan; Ziramba, Emmanuel (University of Pretoria, Department of Economics, 2008-06)
    Using an overlapping generations monetary endogenous growth model, we analyze the possible misalignment in the growth-maximizing policies if tax evasion is assumed to be exogenous instead of being treated as a behavioral ...
  • Mobilising tax revenue to finance development : the case of property taxation in francophone Africa 
    Monkam, Nara F. (University of Pretoria, Department of Economics, 2010-11)
    In the context of a widespread focus on decentralisation in Africa, there has been an imperative to find suitable ways to maximise potential own revenue sources at all sub-national government levels. This need in particular ...
  • Modeling the marginal revenue of water in selected agricultural commodities : a panel data approach 
    Blignaut, James Nelson; Van Eyden, Renee; Moolman, Christina Elizabeth (University of Pretoria, Department of Economics, 2006-02)
    South Africa is a water-stressed country where water availability is an important constraint to economic and social development, and will become even more so in the future if this scarce resource is not managed effectively. ...
  • Modelling and forecasting the metical-rand exchange rate 
    Gupta, Rangan; Zita, Samuel (University of Pretoria, Department of Economics, 2007-02)
    This paper investigates the ability of the Dornbusch (1976) sticky-price model for the nominal metical-rand exchange rate, over the period 1994:1-2005:4 in explaining the exchange rate movements of Mozambique. Based on ...
  • Modelling monetary policy in South Africa : focus on inflation targeting era using a simple learning rule 
    Naraidoo, Ruthira; Gupta, Rangan (University of Pretoria, Department of Economics, 2009-01)
    A simple empirical nonlinear framework is used to analyse monetary policy between 1983 and 2007 in South Africa, focusing on the policy of inflation targeting introduced in Feb 2000, more precisely when the South African ...
  • Modelling the impact of automatic fiscal stabilisers on output stabilisation in South Africa 
    Ngoie, Jacques Kibambe; Schoeman, N.J. (Nicolaas Johannes) (University of Pretoria, Department of Economics, 2009-12)
    This paper investigates ways in which an efficiency model like DEA Window analysis can be utilised, under strictly defined conditions, to assess the level of efficiency of automatic fiscal stabilisers (AFS). The size of ...
  • Monetary policy and housing sector dynamics in a large-scale Bayesian vector autoregressive model 
    Gupta, Rangan; Jurgilas, Marius; Kabundi, Alain; Miller, Stephen M. (University of Pretoria, Department of Economics, 2009-06)
    Our paper considers the channel whereby monetary policy, a Federal funds rate shock, affects the dynamics of the US housing sector. The analysis uses impulse response functions obtained from a large-scale Bayesian Vector ...
  • A new-Keynesian DSGE model for forecasting the South African economy 
    Gupta, Rangan; Liu, Guangling; Schaling, Eric (University of Pretoria, Department of Economics, 2008-04)
    This paper develops a New-Keynesian Dynamic Stochastic General Equilibrium (NKDSGE) Model for forecasting the growth rate of output, inflation, and the nominal short-term interest rate (91-days Treasury Bills rate) for ...
  • Nonlinear tax elasticities and their implications for the structural balance 
    Jooste, Charl; Naraidoo, Ruthira (University of Pretoria, Department of Economics, 2010-10)
    Research on tax elasticities in South Africa mainly employs linear models and shows that taxes evolve symmetrically irrespective of the economic cycle. This study extends this research to show that taxes behave asymmetrically ...
  • On health insurance and household decisions : an econometric policy analysis 
    Koch, Steven F.; Alaba, Olufunke A. (University of Pretoria, Department of Economics, 2008-07)
    In developing countries, health insurance is not a commonly purchased financial instrument. Recent debates have revolved around extending health insurance coverage to a wider range of the population, primarily via compulsory ...
  • On the real exchange rate effects of higher electricity prices in South Africa 
    Blignaut, James Nelson; Jordaan, Andre Cillie; Van Heerden, J.H. (Jan Horn), 1957- (University of Pretoria, Department of Economics, 2008-09)
    The paper uses a static Computable General Equilibrium (CGE) model of South Africa and simulates various shocks to the price of electricity. We attempt different closures to the model and compare their respective effects ...
  • Openness, bureaucratic corruption and public policy in an endogenous growth model 
    Gupta, Rangan; Ziramba, Emmanuel (University of Pretoria, Department of Economics, 2008-06)
    In this paper, we develop a dynamic general equilibrium overlapping generations monetary endogenous growth model of a financially repressed small open economy characterized by bureaucratic corruption, and, in turn, analyze ...
  • Optimal monetary policy reaction function in a model with target zones and asymmetric preferences for South Africa 
    Naraidoo, Ruthira; Ndahiriwe, Kasai (University of Pretoria, Department of Economics, 2010-03)
    In this paper we provide an in-sample assessment of how the South African Reserve Bank (SARB) sets policy rate in the context of both linear and nonlinear Taylor type rule models of monetary policy. Given the controversial ...
  • Optimal monetary policy reaction function in a model with target zones and asymmetric preferences for South Africa 
    Naraidoo, Ruthira; Raputsoane, Leroi Jeremia (University of Pretoria, Department of Economics, 2010-03)
    This paper estimates the optimal monetary authorities’ response to deviations of inflation and output from their target values for South Africa over the inflation targeting era. This is achieved using an empirical framework ...
  • Optimal public policy with endogenous mortality 
    Gupta, Rangan; Ziramba, Emmanuel (University of Pretoria, Department of Economics, 2008-08)
    Using a monetary pure-exchange overlapping generations model, where the probability of survival of the young agents depends upon share of government expenditure on health, education and infrastructure, we analyze the ...
  • Pattern of interdependence of aggregate FDI from the same source country 
    Kemegue, Francis M. (University of Pretoria, Department of Economics, 2009-12)
    This paper explores the possibility that monitoring resources explain the clustering in space of aggregate FDI from the same source country. Theoretically, the paper shows that independently of any institutional incentive ...
