a r t i c l e i n f o We explore the sectoral and aggregate implications of some endogeneization rules (i.e. on value-added and final demand) which have been common in the extended demand-driven Leontief model and have been recently proposed in the supply-driven Ghosh model. Extended linear models are refinements that aim at endowing the linear models with additional general equilibrium feedbac...

Efficient estimates require the utilization of all the available theoretical and statistical information. This fact suggests that econometric models based on an explicit optimization theory might achieve more efficient estimates when all the primal and dual relations are used for a joint estimation of the model’s parameters. We present a discussion of this idea using a Linear Expenditure System...

Production planning under uncertain demands leads to optimisation problems that are hard both to model and to solve. We describe an integer linear model for a template design problem under uncertainty, and investigate its solution by a general-purpose local search algorithm for integer linear programs. Several such algorithms have previously been proposed as tools for solving large combinatoria...

The Traffic demand of the communication has strong relations to the gross domestic product (GDP). Some statistical models are well known for the demand forecast. As such models, there are the Linear regression Model (LM) and the Auto Regression model (AR). However the LM cannot apply analyzing a traffic demand, because its relations between a GDP and a traffic demand have the non linear shape. ...

We invent Implicit Marshallian Demands, a new type of demand function that combines desirable features of Hicksian and Marshallian demand functions. We propose and estimate the Exact Af ne Stone Index (EASI) Implicit Marshallian Demand system. Like the Almost Ideal Demand (AID) system, EASI budget shares are linear in parameters given real expenditures. However, unlike the AID, EASI demands can...

This study deals with the effects of a supply chain (SC) with single product, multiple retailers and a manufacturer, where the manufacturer(he) produces lotsize of the product that contains a random portion of imperfect quality item. The imperfect quality products are sold in a secondary shop. The new contribution of this paper is a new non-linear demand function. Demand of the end customers va...

This paper compares demand estimation with and without full supply information in non-linear models. The main result is that, in a non-linear model, under general monotonicity conditions, there is a speci cation of the full supply model which is consistent with an arbitrarily speci ed auxiliary equation to account for endogeneity in demand estimation. In particular, there is a speci cation of t...
