This paper develops a monetary endogenous growth overlapping generations model characterized by production lags - specically lagged capital inputs - and an in ation targeting monetary authority, and analyses the growth dynamics that emerge from this framework. The growth process is endogenized...

In ation forecasts are a key ingredient for monetary policymaking - especially in an in ation targeting country such as South Africa. Generally, a typical Dynamic Stochastic General Equilibrium (DSGE) only includes a core set of variables. As such, other variables,e.g. such as alternative...

This paper analyses the empirical relationship between inflation and growth using a panel data estimation technique, Multiple Regime Panel Smooth Transition Regression (MR-PSTR), which takes into account the nonlinearities in the data. By using a panel data set for 10 African countries that...

We use a copula approach to investigate the effect of uncertainty on crude-oil returns. Using copulas to construct multivariate distributions of time-series data permit the calculation of the dependence structure between the series independently of the marginal distributions. Further, we...

The aim of this paper is to investigate the causal relationship between agricultural prices in South Africa and global oil prices. A nonlinear Granger causality test based on moment conditions, introduced by Nishiyama et al (2011) is employed and we find that there is indeed a causal...

This paper uses a k-th order nonparametric Granger causality test to analyze whether firm-level, economic policy and macroeconomic uncertainty indicators predict movements in real stock returns and their volatility. Linear Granger causality tests show that whilst economic policy and...

In this paper we evaluate inflation persistence in the U.S. using long range monthly and annual data. The importance of inflation persistence is crucial to policy authorities and market participants, since the level of inflation persistence provides an indication on the susceptibility of the...

This paper investigates the asymmetric and nonlinear transmission of financial and energy prices to US five-year financial CDS sector index spreads for the banking, financial services and insurance sectors in the short- and long-run over the recent periods including the world financial crisis....

Given the existence of non-normality and nonlinearity in the data generating process of real house price returns over the period of 1831-2013, this paper compares the ability of various univariate copula models, relative to standard benchmarks (naive and autoregressive models) in forecasting...

The Feldstein-Horioka (FH) puzzle, that is the strong correlation between saving and investment in a world where obstacles to capital mobility are limited, has been studied extensively since it was exposed in 1980. Even though the theoretical and empirical literature has examined many of its...
