The foundation of specialised economic journals was one of the main traits in the process of institutionalisation of political economy in 19th century Western Europe. Spain joined this trend at an early stage and in the 1850s and 1860s some specialised, albeit ephemeral, journals sponsored by the liberal school of economic thought – the Economist School – emerged. However, when these reviews ceased publication, Spanish economists lacked specialised periodicals as an outlet for their contributions. Miscellaneous literary reviews addressing a wider audience represented an alternative for the diffusion of economic papers into educated society, sharing space with many other scientific and literary disciplines. This paper analyses the presence of texts on political economy in four of the most important of these reviews in the period 1868-1914, when Spain lacked economic publications. In spite of not being specialised reviews, these publications played a central role in the process of diffusion and popularisation of political economy as a valuable field of knowledge, acting as a good substitute for specifically economic journals.
