Econometric Modeling of Input-Driven Output Risk through a Versatile CES Production Function

چکیده
The conventional functional form of the Constant-Elasticity-of-Substitution (CES) production function is a general nesting number other forms functions. Examples such functions include Leontief, Cobb–Douglas, and linear Nevertheless, CES specification still restrictive in multiple aspects. One example fact that marginal effect increasing input use always has to be increase variability output quantity by construction this function. This paper proposes generalized variant allows for various effects on probability distribution output. Failure allow possible input–output risk structure indeed one limitations limitation may result false inferences about input-driven risk. In light this, present solution problem. First, it shown familiar formulation suffers from very structural assumptions regarding considerations, restrictions lead biased inefficient estimates Following theme Just Pope’s approach, CES-based production-function overcomes shortcoming original introduced, three-stage Nonlinear Least-Squares (NLS) estimation procedure proposed presented. To illustrate approaches paper, two empirical applications irrigation fertilizer response using famous Hexem–Heady experimental dataset are provided. Finally, implications modeling risks discussed.

متن کاملA Young EFL Learner’s Lexical Development through Different Input and Output Frequency Patterns
The present study was undertaken to investigate the effects of varying frequency patterns (FPs) of words on the productive acquisition of a young EFL learner in a home setting. Target words were presented to the learner using games and role plays. They were subsequently traced for their frequencies in input and output. Eighteen immediate tests and delayed tests were administered to measure the ...
متن کاملTesting the Role of Input-Output Linkages in Industry Agglomeration with the Spatial Econometric and Input-Output Model
This paper examines the relationship between input-output linkages and industry agglomeration by combining the strength of spatial econometrics and the input-output model. This paper uses the location quotient as a measure of industrial agglomeration and regresses it on the intermediate demand variable, which is an important variable in the integrated econometric and input-output models. The na...
متن کاملA Comparison of Input and Output Driven Routers
Communication in parallel computers requires a low latency router. Once a suitable routing algorithm is selected, an implementation must be designed. Issues such as whether the router should be input or output driven need to be considered. In this paper, we use simulations to compare input driven and output driven routing algorithms. Three algorithms, the Dally-Seitz oblivious router, the *-cha...
