In this study, we used a household level survey to assess choices of varieties and demand for improved cassava varieties. A multivariate probit model was examine the determinants choice decisions farmers different preventing potential endogeneity measurement error. Linearized Almost Ideal Demand System (LA/AIDS) analyze system The results indicated were very price sensitive changes in stem pric...

This article deals with the specification of a locally flexible and theory-consistent system of mixed demand functions, a framework that allows for a rich set of possibilities about what is assumed as exogenous in a demand model. A coherent mixed demand system is derived by using the restricted expenditure function typically studied in the related area of rationed demands. The method is impleme...

We consider a financial model where the prices of risky assets are quoted by a representative market maker who takes into account an exogenous demand. We characterize these prices in terms of a system of BSDEs with quadratic growth. We show that this system admits a unique solution for every bounded demand if and only if the market maker’s risk-aversion is sufficiently small. The uniqueness is ...

This paper develops an economic lot-sizing production model for deteriorating items with time dependent quadratic demand and delay in payments under two levels of trade credit policy. The trade credit policy adopted here is a two-level trade credit policy in which the supplier offers the retailer a permissible delay period M, and the retailer in turn provides customers a permissible delay perio...

In this paper we investigate Gaussian composition. Furthermore, we study the correspondence theorem of ideal classes and classes of binary quadratic forms. We also show a generalization of this correspondence and composition to higher dimensions recently discovered by Manual Bhargava. Along with this generalization, Gaussian composition is one of at least 14 such correspondences. Although, more...

India has been running large-scale interventions in the energy sector over the last decades. Still, there is a dearth of reliable and readily available price and income elasticities of demand to base these on, especially for domestic use of traditional fuels. This study uses the linear approximate almost ideal demand system (LA-AIDS) using micro data of more than 100,000 households sampled acro...

Tourism forecasting plays an important role in tourism planning and management. Various forecasting techniques have been developed and applied to the tourism context, amongst which econometric forecasting has been winning an increasing popularity in tourism research. This paper therefore aims to introduce the latest developments of econometric forecasting approaches and their applications to to...

The global shift towards diets high in sugar-sweetened beverages (SSBs) is linked to higher prevalence of obesity, diabetes and most other non-communicable diseases. In Colombia, one out of every two people was overweight or obese by 2010. This study estimates price-elasticities from a Quadratic Almost Ideal Demand System model, using the 2006-2007 Colombian Income and Expenditure survey. The f...
