Magariño Lafalla V. (2026). The Classical Theory of Relative Prices: Evidence from the Spanish Economy. Iberian Journal of the History of Economic Thought, 13(1), 49-65. https://doi.org/10.5209/ijhe.99633
Abstract
Este artículo examina el desarrollo y la posición actual de la teoría del valor y la distribución predominante en las tradiciones clásica y marxista del pensamiento económico, explorando a su vez su adecuación empírica en datos de insumo-producto de España para los años 2010, 2015 y 2016. Se utilizan estimaciones de precios directos y precios de producción para medir su proximidad, así como la distancia de cada uno de ellos a los precios de mercado. El sistema clásico/marxista de precios de producción también se somete a pruebas para evaluar la posibilidad de una curvatura pronunciada de precios. Los resultados sugieren que los tres conjuntos de precios son significativamente cercanos entre sí, lo que refuerza el respaldo empírico a la hipótesis transversal derivada de esta concepción de los precios relativos. Además, la evidencia recopilada de la economía española no respalda la existencia de curvas de precios distorsionadas como fenómeno empíricamente relevante.
Abstract. This paper examines the development and current standing of the theory of value and distribution dominant in the classical and Marxian traditions of economic thought, while exploring its empirical adequacy in Spanish input-output data for the years 2010, 2015 and 2016. Estimates of direct prices and prices of production are used to measure their respective proximity, as well as the distance from each to market prices. The classical/Marxian system of prices of production is also subjected to testing for the possibility of pronounced price curvature. The results suggest that all three sets of prices are significantly close to each other, thereby strengthening the empirical support for the cross-sectional hypothesis derived from such account of relative prices. In addition, the evidence gathered from the Spanish economy does not support the case for twisted price curves as an empirically relevant phenomenon.
