Résumé
The purpose of this study is to obtain insights into the pricing mechanisms pursued by the government of Morocco in light of uncertainty, dynamics and openness of the economy. The study focuses on Moroccan soft wheat sector. A theoretical model is developed based on constrained optimization behavior of private agents. The government’s strategy is based on an intertemporal model which permits the derivation of reduced form rules for assessing consumer and producer pricing processes. The hypotheses obtained are tested using time-series analysis applied to market and official soft wheat price data (1960-1965). This estimation uses Box-Jenkins techniques, Sims exogeneity test, Granger causality and Haugh-Pierce test of independence. Univariate and bivariate models are obtained and compared to the theoretical decision rules. An ordering of the discriminatory weights is derived to express government preferences toward agents. Welfare implications are obtained by comparing consumer and producer prices to world price. The results provide insights into the economic rationale of government’s pricing strategy. They concern also the revelation of implicit objectives and intentions which might have been pursued by Moroccan soft wheat pricing policies under different hypotheses of expectation formation.
