Abstract

Demand‐side multipliers have ruled within multisectorial models as the main indicators for policy effectiveness and key‐sector determination both in linear interindustry analysis and in non‐linear applied general equilibrium models. In this paper we shift the perspective to supply‐side injections by studying the effects of marshalling additional primary factors (K, L) that give rise to a general resource reallocation. We obtain estimates of supply multipliers by numerically approximating the underlying and unobservable general equilibrium Jacobian matrix. These estimates provide complementary information to standard demand multipliers. We illustrate the methodology using an empirical general equilibrium model for the region of Andalusia, Spain. En los modelos multisectoriales, los multiplicadores de la demanda han sido los principales indicadores de la eficacia de las políticas y de la determinación de los sectores clave, tanto en el análisis lineal interindustrial como en los modelos de equilibrio general aplicados no lineales. En este artículo se cambia la perspectiva sobre las inyecciones del lado de la oferta mediante el estudio de los efectos de reunir los factores primarios adicionales (K, L) que dan lugar a una reasignación general de recursos. Se obtuvieron estimaciones de los multiplicadores de la oferta mediante la aproximación numérica de la matriz jacobiana de equilibrio general subyacente e inobservable. Estas estimaciones proporcionan información complementaria a los multiplicadores estándar de la demanda. Se ilustra la metodología utilizando un modelo empírico de equilibrio general para la región de Andalucía en España. 需要サイドの乗数はこれまで、マルチセクターモデルの中で、線形産業間分析と非線形応用一般均衡モデルの両方で、政策効果およびキーセクター決定の主な指標として支配的である。本稿では、一般資源の再配分を起こす付加的な一次因子(K,L)の相互変換の効果を調査して、供給サイドの注入に視点を移す。我々は、潜在的で認識できない一般均衡のヤコビ行列を数値的に近似させることにより、供給乗数の推計を行った。この推計が標準の需要乗数に補完的情報をもたらす。本稿では、スペインのアンダルシア地方に適用した実証的一般均衡モデルを用いて、この方法を説明する。.
