How does the South African government react to changes in its debt position? In investigating this question, this paper estimates fiscal reaction functions using various methods (ordinary least squares, threshold autoregressive, state‐space modelling and vector error‐correction model). This paper finds that since 1946, the South African government has run sustainable fiscal policy by reducing the primary deficit or increasing the surplus in response to rising debt. Looking ahead, this paper considers the use of fiscal reaction functions to forecast the debt/gross domestic product (GDP) ratio and gauging the likelihood of achieving policy goals with the aid of probabilistic simulations and fan charts.
This study assesses how fiscal policy affects the dynamics of asset markets, using Bayesian vector autoregressive models. We use sign restrictions to identify government revenue and government spending shocks, while controlling for generic business cycle and monetary policy shocks. Using South African quarterly data from 1966:Q1 to 2011:Q2, we find that fiscal spending shocks affect stock prices more than house prices. Both spending and revenue shocks affect stock prices whereas only revenue shocks affect house prices.
The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.
The pass‐through of shifts in the rand exchange rate to consumer price inflation has been well documented for South Africa. Although estimates of the absolute level of pass‐through vary, some studies document a decline in pass‐through over time. In order to better illuminate the policy implications of pass‐through, this paper seeks to add to the literature by decomposing pass‐through into a number of time‐varying impulses. This has the advantage of providing deeper insights of pass‐through over time and across various monetary policy regimes. We then analyse the determinants of time‐varying pass‐through. Our results confirm that pass‐through has declined over time but is subject to a stable and low inflation environment. We also show that a volatile exchange rate leads to higher pass‐through.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
