Essays in production theory : efficiency measurement and comparative statics

Mendoza, Maria Nimfa F. January 1989 (has links)
Nonparametric linear programming tests for consistency with the hypotheses of technical efficiency and allocative efficiency for the general case of multiple output-multiple input technologies are developed in Part I. The tests are formulated relative to three kinds of technologies — convex, constant returns to scale and quasiconcave technologies. Violation indices as summary indicators of the distance of an inefficient observation from an efficient allocation are proposed. The consistent development of the violation indices across the technical efficiency and allocative efficiency tests allows us to obtain comparative measures of the degrees of technical inefficiency and pure allocative inefficiency. Constrained optimization tests applicable to cases where the producer is restricted to optimizing with respect to a subset of goods are also proposed. The latter tests yield the revealed preference-type inequalities commonly used as tests for consistency of observed data with profit maximizing or cost minimizing behavior as limiting cases. Computer programs for implementing the different tests and sample results are listed in the appendix. In part II, an empirical comparison of nonparametric and parametric measures of technical progress for constant returns to scale technologies is performed using the Canadian input-output data for the period 1961-1980. The original data base was aggregated into four sectors and ten goods and the comparison was done for each sector. If we assume optimizing behavior on the part of the producers, we can reinterpret the violation indices yielded by the efficiency tests in part I as indicators of the shift in the production frontier. More precisely, the violation indices can be considered nonparametric chained indices of technical progress. The parametric measures of technical progress were obtained through econometric profit function estimation using the generalized McFadden flexible functional form with a quadratic spline model for technical progress proposed by Diewert and Wales (1989). Under the assumption of constant returns, the index of technical change is defined in terms of the unit scale profit function which gives the per unit return to the normalizing good. The empirical results show that the parametric estimates of technical change display a much smoother behavior which can be attributed to the incorporation of stochastic disturbance terms in the estimation procedure and, more interestingly, track the long term trend in the nonparametric estimates. Part III builds on the theory of minimum wages in international trade and is a theoretical essay in the tradition of analyzing the effects of factor market imperfections on resource allocation. The comparative static responses of the endogenous variables — output levels, employment levels of fixed-price factors with elastic supply and flexible prices of domestic resources — to marginal changes in the economy's exogenous variables — output prices, fixed factor prices and endowments of flexibly-priced domestic resources -— are examined. The effect of a change in a fixed factor price on other flexible factor prices can be decomposed Slutsky-like into substitution and scale effects. A symmetry condition between fixed factor prices and flexible factor prices is obtained which clarifies the concepts of "substitutability" and "complementarity" between these two kinds of factors. As an illustration, the model is applied to the case of a devaluation in a two-sector small open economy with rigid wages and capital as specific factors. The empirical implementation of the general model for the Canadian economy is left to more able econometricians but a starting point can be the sectoral analysis performed in Part II. / Arts, Faculty of / Vancouver School of Economics / Graduate

Examination of North Dakota's Production, Cost, and Profit Functions: A Quantile Regression Analysis

Marroquin, Jacklin Beatriz January 2008 (has links)
This thesis estimates the production, cost, and profit functions for North Dakota agriculture using state-level input-output quantity and price data for the period 1960-2004. A Cobb-Douglas functional form with Hick-neutral technology change is used to measure the contribution of capital, land, labor, materials, energy, and chemical inputs quantities and output quantity using the primal production function; contribution of capital quantity, land quantity, output quantity, labor price, materials price, energy price, and chemical price to cost using the dual restricted cost function; and the contribution of capital quantity, land quantity, labor price, materials price, energy price, chemical price, output price to profit using the dual restricted profit function. In contrast to previous studies, quantile regression is used to explore the linear or nonlinear relationship between the independent and dependent variable by estimating parameter coefficients at each quantile using time-series data. Empirical findings suggest the cost function is the best model to examine the relationship between input prices, output quantity and cost using quantile regression for North Dakota agriculture, Further, the quantile regression suggests a linear and non-linear relationship between cost and certain independent variables.

Health Sector Labour Market Dynamics and Multi-Employer Collective Agreements

Hogan, James Lawrence January 2014 (has links)
How New Zealand’s health-sector labour markets interact with District Health Board (DHB) Provider Arms is my thesis’ focus. Using health-service delivery data, workforce data, and DHB monthly financial information, I estimate the DHB Provider Arm economic production process and the interaction between DHBs and the health-sector labour and capital input markets. Production and input market interactions are modelled through simultaneously estimating a DHB production function together with the first order conditions for cost-minimisation in an econometric system-of-equations. Estimating a system-of-equations allows labour and capital market prices to interact with DHB marginal input productivities according to the first order conditions of cost-minimisation. Nationally-determined MECA labour prices influence health service output through their equality to DHB production-based input marginal productivities. Medical and nursing labour appears to have inelastic labour demand, providing scope for unions in those sectors to exploit market power. DHBs are employing fewer workers than they would and paying more for each worker than they should if the labour market was more competitive. New Zealanders are receiving less health care then they might, and experiencing more morbidity then they need bear, from the workforce restrictions generated in the health sector's labour market. The passed-through inflated labour costs are borne by taxpayers, who lack options for alternative provider care. The non-competitive labour market induce secondary labour market effects. Overseas-trained medical labour, attracted into New Zealand by above-competition wages, are denied employment within medical-skill-hungry DHBs. Graduate nurses over-supply a quantity-constrained labour market, generated entrenched unemployment. DHBs are induced to be allocative and technically inefficient through price distortions, creating higher output costs and an inefficient production input mix.

Posouzení stavu malých vodních nádrží z hlediska jejich krajinných funkcí. / Assessment of the condition of small water reservoirs in terms of landscape functions.

RUČ, Karel January 2013 (has links)
This thesis is focused on evaluation of landscape functions of small water reservoirs. The aim is to analyze their basic parameters. For this purpose a realized project of the whole range of water reservoirs with special focus on revitalization was chosen. The source materials and the field research contributed to the final evaluation of the analysis of the water reservoirs condition before and after their completion. The basic data and revitalizing arrangements were identified according to the chosen indicators and criteria. Prevailing functions of the water reservoirs are derived from these indicators and criteria.

An applied trancendental logarithmic cost function : economies of scale and elasticities of substitution in selected South African manufacturing sectors (1972-1990).

Cobbledick, John. January 1995 (has links)
Moll (1991) has criticised the proposal that demand restructuring should act as the impetus for economic growth in a post-apartheid South Africa on the grounds of, a lack of empirical support. The demand restructuring thesis is premised on two empirically testable assertions: firstly that realisable economies of scale are greater in labour-intensive wage goods sectors than in luxury goods and secondly that in manufacturing as a whole labour can easily substitute for capital. While a number of studies employing either the Cobb-Douglas (Cobb & Douglas, 1948) or Constant Elasticity of Substitution (CES) ( Arrow, Chenery, Minhas & Solow, 1961) functions have attempted to quantify these features of technology, their conclusions are potentially invalid. Both functions impose the maintained hypotheses of homotheticity, homogeneity and seperability a priori. As primary hypothesis tests regarding the magnitude of parameters depend on the validity of both the hypothesis being tested and the underlying maintained hypotheses, the plausibility of maintained hypotheses is an important consideration when choosing a functional form for econometric analysis. Homotheticity and homogeneity constrain the theoretical determinants of economies of scale and seperability. The theoretical determinants of substitution thus limit the contexts in which functions which embody these hypotheses are likely to be appropriate. The mathematical concept of duality has permitted the development of flexible, general functions, such as the Transcendental Logarithmic Cost Function (Christensen, Jorgensen and Lau, 1971, 1973), which rather than imposing, permits the testing of the most commonly imposed maintained hypotheses. By applying this function to three sub-sectors of South African manufacturing both the validity of the commonly imposed maintained hypotheses and the empirical premises of the demand restructuring position are assessed in this dissertation. This application indicates that not only are the hypotheses of homotheticity, homogeneity and seperability invalid but that the inappropriate imposition of homotheticity, homogeneity and seperability invalid but that the inappropriate imposition of homotheticity biases estimates of scale downwards. Evidence also emerges to challenge Moll's (1991) assertions regarding the empirical validity of demand restructuring. / Thesis (M.Com.)-University of Natal, Durban, 1995.

Investigating the level of interdependency between the performance(s) of direct opponent(s) in professional football : a study on teams, positional units and individual players competing in the German Bundesliga

Jamil, Mikael January 2015 (has links)
The purpose of this thesis is to investigate the levels of interdependency (simultaneity) between the performances of two direct opponents in professional football. More specifically, interdependency between performances is investigated at three different levels. Firstly, empirical analyses are conducted in order to assess the levels of interdependency between the performances of two teams in direct competition using team-game observations. Secondly, data on team formations and player starting positions within these formations is utilised in order to uniquely match individual players to a sole opponent on the field of play. Further empirical analyses are then conducted in order to investigate the levels of interdependency at this more isolated individual player level using player-game observations. Finally, an empirical investigation into the levels of interdependency between the performances of a positional unit (defence or attack) and their opposing team (as a collective) is conducted using positional unit-game observations. An exclusive and detailed data set ranging from the 2007-08 season to the 2010-11 season is utilised in order to estimate several production functions for teams, individual players and positional units competing in the German Bundesliga. The results in all empirical analyses confirm that the performance of the opponent is significant. At a team and positional unit level, no evidence is found to suggest that the performances of two direct opponents(s) are interdependent, however the results reveal that the recent past performances of the opponent(s) have a significant linear impact upon the performance of the subject. In particular, relative team form going in to a match is revealed to have a significant impact upon the performance of their opponent. At an individual player level, evidence is found to confirm that the performances of players in direct competition are interdependent thus supporting the sports economics theory of joint production. Specifically, the results reveal that the performances of defenders have a significant and negative impact upon the performances of their opposing attackers.
