  • Tax evasion and financial repression : a reconsideration using endogenous growth models 
    Gupta, Rangan; Ziramba, Emmanuel (University of Pretoria, Department of Economics, 2008-05)

  • Testing for PPP using SADC real exchange rates 
    Gupta, Rangan; Van Eyden, Renee; Mokoena, Thabo Mishack (University of Pretoria, Department of Economics, 2008-06)
    This paper attempts to provide evidence indicating that the Purchasing Power Parity (PPP) puzzle is becoming less of a puzzle. It present the results of Augmented Dickey- Fuller (ADF) test, nonlinear tests of nonstationarity, ...
  • Testing the export-led growth hypothesis for Botswana : a causality analysis 
    Eita, Joel Hinaunye; Jordaan, Andre Cillie (University of Pretoria, Department of Economics, 2007-10)
    This paper investigates the causal relationship between export and economic growth for Botswana, using quarterly data for the period 1995.1-2005.4. It uses two measures of economic growth namely, GDP and GDP excluding ...
  • Time aggregation and the contradictions with causal relationships : can economic theory come to the rescue? 
    Gupta, Rangan; Komen, Kibii (University of Pretoria, Department of Economics, 2008-02)
    The literature on causality takes contradictory stands regarding the direction of causal relationships based on whether one uses temporally aggregated or systematically sampled data. Using the relationship between a ...
  • Time aggregation, long-run money demand and the welfare cost of inflation 
    Gupta, Rangan; Uwilingiye, Josine (University of Pretoria, Department of Economics, 2008-07)
    Two recent studies have found markedly different measures of the welfare cost of inflation in South Africa, obtained through the estimation of long-run money demand relationships using cointegration and long-horizon ...
  • The time-series properties on housing prices : a case study of the Southern California market 
    Gupta, Rangan; Miller, Stephen M. (University of Pretoria, Department of Economics, 2009-02)
    We examine the time-series relationship between housing prices in eight Southern California metropolitan statistical areas (MSAs). First, we perform cointegration tests of the housing price indexes for the MSAs, finding ...
  • Tobacco substitution and the poor 
    Koch, Steven F.; Tshiswaka-Kashalala, Gauthier (University of Pretoria, Department of Economics, 2008-10)
    Tobacco control policies have effectively raised the price of cigarettes and other tobacco products. However, these price increases have been shown to disproportionately fall upon poorer households, with fewer resources. ...
  • The use of a Marshallian Macroeconomic Model for policy evaluation : case of South Africa 
    Ngoie, Jacques Kibambe; Zellner, Arnold (University of Pretoria, Department of Economics, 2010-06)
    Using a disaggregated Marshallian Macroeconomic Model (MMM-DA), this paper investigates how the adoption of a set of 'free market reforms' may affect the economic growth rate of South Africa. Accounting for possible side ...

    Thompson, Kirsten L.; Schoeman, N.J. (Nicolaas Johannes) (University of Pretoria, Department of Economics, 2006-06)
