Using the Spanish economy as a natural case study, we illustrate that, for different preference specifications, 1-year ex-ante real interest rates exhibit a very low correlation with the 1-year ex-post rate. According to our results, the difference between both real rates seems to be mainly explained in terms of agents' inflation expectation errors, while the inflation premia play a minor role.Usando el marco proporcionado por el modelo CCAPM podemos estimar conjuntamente tipos de interés reales ex-ante, y cotas a las expectativas de inflación y primas de riesgo inflacionista. Utilizamos la economía española para ilustrar la baja correlación existente entre los tipos reales ex-ante a un año y sus correspondientes tipos ex-post. Nuestros resultados confirman la importancia de las expectativas de inflación para explicar tales diferencias.Tots els drets reservatshttp://www.europeana.eu/rights/rr-f/Article de fons.Inflation expectation errorsinflation risk premiapreference specificationserrores de expectativas de inflaciónprima de riesgo inflacionistapreferenciasarticleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionLópez Salido, J.
