Using the most recently available data, this paper estimates the price and income elasticities of gasoline demand in the United States from a semiparametric smooth coefficient model. The econometric approach provides more flexibility by allowing functional coefficients to accommodate heterogeneity in gasoline demand. Instrumental variables are used to correct for the potential endogeneity of th...

The objective of the present Position Paper is to identify the major theoretical and practical developments dealing with Airport Capacity and Efficiency optimisation and improvement. Furthermore, it is within the scope of this document to identify and present in detail the major institutional / organizational and technical / operational factors associated with Airport Capacity and Efficiency, e...

Our research concerns formal, expressive, objectcentred languages and tools for use in engineering domains for planning applications. In this paper we extend our recent work on an object-centred language for encoding precondition planning domains to a language called OCLh, designed for HTN planning. Domain encodings for HTN planners are particularly troublesome, because they tend to be used in ...

This paper examines costs in the Swiss nursing home industry, an issue of concern to Swiss policy makers because of the explosion of elderly care costs and the aging of the population. The paper considers estimation of a translog cost function employing panel data for a sample of 36 nonprofit nursing homes operating in Ticino, a canton of Switzerland, over the period 1993-1995. Using a set of d...

In this paper a model of dynamic factor demands is presented for the Irish economy. Total costs, labour and capital are modelled on a two-stage basis. First, a static, long-run cost function is specified which allows for the derivation of expressions for optimal labour and capital demand. This function is assumed to be of the flexible, translog form and thus more general than the generic Cobb-D...

Fertilizer has brought great pressure to sustainable ecological environment. Research on the effect of price fertilizer use as well substitution relationship and other input factors agricultural production is importance for green, efficient, intensive in world. This study first constructs translog cost functions models elasticity, then uses factor data from 2004 2016 measure elasticity demand, ...

Abstract A spatially analyse of the production structure and input choices for heating, sawmill, pulp sectors in Sweden is conducted using a panel data set includes quarterly period 2011 to 2016 across 21 counties. Focus on price substitution elasticities, scale effects technical change measures. single-output regional translog cost models developed estimated. The specification chosen its flexi...

The present study aims to estimate the marginal cost of potable water supply and analyse implications for more efficient, equitable income-adequate tap tariffs in Tunisia. Furthermore, this article develop a new pricing model water. Pricing by Tunisian utility focuses on setting prices cover average costs, often using designs that increase clogging rates. This results large volume being wasted....
