Persistence in silver prices and the influence of solar energy

Resumen:
This paper deals with the analysis of silver prices and the influence of solar energy on its behaviour. For this purpose, the analysis uses long memory methods based on fractional integration and cointegration. The results indicate that the two variables are very persistent, though any long run equilibrium relationship between them is not observed. Nevertheless, the results illustrate some short-run negative effects from solar energy capacity on silver prices.
