PRODUCTIVITY AND UNDESIRABLE OUTPUTS: A DIRECTIONAL DISTANCE FUNCTION APPROACH by
نویسندگان
چکیده
Undesirable outputs are often produced together with desirable. This joint production of good and bad outputs bring about a difficulty for productivity measurement. Here we introduce a directional distance function and use it as a component in a new productivity index. This index, as an empirical example shows, seems to solve the problem caused by the joint production of good and bad outputs.

Interval Malmquist Productivity Index in DEA
Data envelopment analysis is a method for evaluating the relative efficiency of a collection of decision making units. The DEA classic models calculate each unit’s efficiency in the best condition, meaning that finds a weight that the DMU is at its maximum efficiency. In this paper, utilizing the directional distance function model in the presence of undesirable outputs, the efficiency of each ...
متن کاملProductivity? of US Airlines After Deregulation
In measuring productivity in the presence of undesirable outputs, traditional growth accounting and index number approaches face the problem that prices of the undesirable outputs typically do not exist since such outputs are generally not marketed. In this paper we employ an alternative measure of total factor productivity based on a generalization of the Shephard distance functions, namely wh...
متن کاملRole of Freight Transportation Services and Reduction of Delayed Flights on Productivity of US Airports
Annually million tons of freight and mail are being transported through US airports. The air freight transportation services reportedly result in millions of jobs, activities and dollars which in effect stimulate economic development of regions and the nation as a whole. Beyond passengers and aircraft movements, freight volume nowadays is another major target of opportunity for an airport manag...
متن کاملThe Role of Environmental Factors in Growth Accounting: a Nonparametric Analysis*
This paper explores a relatively new methodology, the directional distance function method, to analyze productivity growth. The method explicitly evaluates the role undesirable outputs of the economy, such as carbon dioxide and other green-house gases, have on the frontier production process which we specify as a piece-wise linear and convex boundary function. We decompose productivity growth i...
متن کاملBayesian Approach to Disentangling Technical and Environmental Productivity
This paper models the firm’s production process as a system of simultaneous technologies for desirable and undesirable outputs. Desirable outputs are produced by transforming inputs via the conventional transformation function, whereas (consistent with the material balance condition) undesirable outputs are by-produced via the so-called “residual generation technology”. By separating the produc...
