RESUMENEn este artículo se examinan las preferencias declaradas de los consumidores hacia las nueces, mediante un experimento de eleccion, con un doble objetivo: primero, identificar los atributos más relevantes para el consumidor a la hora de adquirir este fruto y, segundo, estimar las...

RESUMEN: La diferencia temporal existente entre la planificación de la oferta y la demanda de productos agrarios, conlleva a que, tradicionalmente, en sectores como el de frutas y hortalizas cobren gran interés las teorías sobre formación de expectativas de precios. En las últimas décadas,...

The GTAP model, versions 4.1 and lower, suffers from some defects in the implementation of the regional household demand system. Most seriously, the upper level of the demand system assumes that each regional household faces a fixed price for utility from private consumption. But with a private...

The making of projections often requires an economy-wide perspective, and the estimation of consumer demands at the international level. In this paper, an implicit, directly additive demand system (AIDADS) is estimated using cross-country data on consumer expenditures from the International...

Structural change in meat consumption has been the focus of many researchers during the last two decades. In this paper we develop a dynamic linear Almost Ideal Demand System (AIDS) model from a cost function that allows for time varying parameters. This model is consistent with inertia in the...

Product-line length, or variety, is a key competitive tool used by retailers to differentiate themselves from rivals. Theoretical models of price and variety competition suggest that both store and product heterogeneity are key determinants of price and variety strategies, but none test this...

The price elasticity of demand for credit has major implications for macroeconomics, finance, and development. We present estimates of this parameter derived from a randomized trial. The experiment was implemented by a consumer microfinance lender in South Africa and identifies demand curves...

What is the relation between infrequent price adjustment and the dynamic response of the aggregate price level to monetary shocks? The answer to this question ranges from a one-to-one link (Calvo, 1983) to no connection whatsoever (Caplin and Spulber, 1987). The purpose of this paper is to...

In this study demand relations for primary oilseeds in South Africa is estimated and interpreted with the use of econometric models. Two different models, namely the Linear Approximate Almost Ideal Demand System (LA/AIDS) and the two-step Error Correction Model (ECM), were applied to annual...
