Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to provide a general overview of the econometrics of panel data, both from a theoretical and from an applied viewpoint. Since the pioneering papers by Edwin Kuh (1959), Yair Mundlak (1961), Irving Hoch (1962), and Pietro Balestra and Marc Nerlove (1966), the pooling of cross sections and time series data has become an increasingly popular way of quantifying economic relationships. Each series provides information lacking in the other, so a combination of both leads to more accurate and reliable results than would be achievable by one type of series alone. Over the last 30 years much work has been done: investigation of the properties of the applied estimators and test statistics, analysis of dynamic models and the effects of eventual measurement errors, etc. These are just some of the problems addressed by this work. In addition, some specific diffi culties associated with the use of panel data, such as attrition, heterogeneity, selectivity bias, pseudo panels etc., have also been explored. The first objective of this book, which takes up Parts I and II, is to give as complete and up-to-date a presentation of these theoretical developments as possible. Part I is concerned with classical linear models and their extensions; Part II deals with nonlinear models and related issues: logit and pro bit models, latent variable models, duration and count data models, incomplete panels and selectivity bias, point processes, and simulation techniques.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study aims at improving our understanding of the individual contribution of the components of total factor productivity (TFP) change to U.S. agricultural productivity. A novel sequential primal-dual estimation routine to calculate TFP change is proposed, using a multi-output input distance function in the first stage, followed by a cost minimization routine in the second stage. TFP change is estimated as the direct sum of the estimates of technical change, technical efficiency change, allocative efficiency change, input price effects, changes in output markup, and changes in returns to scale in each state. The validity of the proposed methodology is supported by the remarkable overlap and high correlation of our annual estimates of TFP change with the USDA's measures of change in TFP by state. Although technical change tends to be the largest contributor to productivity change, it bears a low and statistically insignificant correlation with TFP change on an annual basis, whereas annual changes in the markup effect and returns to scale are highly and significantly correlated with TFP changes. This is the first study to find a slowdown of technical progress in the U.S. farm sector in the 1990s and 2000s, and technical regress during the farm crisis of the 1980s. While technical efficiency shows a positive overall trend, allocative efficiency shows a negative overall trend, and their combined effect (i.e., the overall cost efficiency) slows down TFP growth. The policy recommendations from previous studies on the drivers of TFP should be revised in light of these findings.

This book was released on 2012-12-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors draw on a 3-year project that analyzed a Portuguese area in detail, comparing this study with papers from other regions. Applications include the estimation of technical efficiency in agricultural grazing systems (dairy, beef and mixed) and specifically for dairy farms. The conclusions indicate that it is now necessary to help small dairy farms in order to make them more efficient. These results can be compared with the technical efficiency of a sample of Spanish dairy processing firms presented by Magdalena Kapelko and co-authors.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Total-factor productivity (TFP) is a variable which accounts for effects in total output not caused by traditionally measured inputs of labour and capital. If all inputs are accounted for, then total factor productivity can be taken as a measure of an economy’s long-term technological change or technological dynamism, scale of economies and efficiency.TFP is regarded as the more accurate productivity measure than the partial productivity measure. The broader the coverage of resources, the better is the productivity measure. The best measure is one that compares output with the combined use of all resources” (Chandel, 2007). TFP is the change in output relative to a weighted combination of all inputs, where the weights are factor shares. Some authors also define TFP as contribution of non-traditional inputs to output. For example non inputs were technology, irrigation, infrastructure, managerial skills and so on.The calculated TFP is decomposed in to a) Scale of economies b) Technical change and c) Residual or Efficiency or Management to know the contribution of non-conventional inputs to the output growth.There are different approaches for estimation of TFP, such as Production function approach, Growth accounting approach and Non-Parametric approach.World ScenarioCoelli, et al., 2003, conducted a study on Total Factor Productivity growth in Agriculture: A Malmquist index analysis of 93 Countries. The results shown that, Asia as a region posted the highest TFP growth of 2.9 percent followed by North America (consisting of USA and Canada), Australasia, Europe, Africa and South America. South America has posted the lowest growth rate of 0.6 per cent followed by Africa with 1.3 per cent growth in TFP. A surprising result is that over the period 1980-2000. The results on continent-level information for six regions revealed that, the largest difference occurs for South and Central America, where the average TFP growth measure increases from 0.6 percent to 1.5 per cent per annum.Country ScenarioChand et al., 2011, estimated average annual TFP growth for the major crops cultivated in India. Among cereals, wheat experienced the highest growth in TFP index during the three decades from 1975 to 2005. Among pulses, the TFP growth was estimated to be 0.5 per cent for moong, followed by gram (0.2 per cent). TFP for Arhar and Urad crops displayed a decline over the past three decades. The TFP is a useful indicator of changes in long-term productivity. The TFP growth (TFPG) in the oilseed sector varied in the range 0.7-0.8 per cent per annum.An attempt was made to analyze the TFP of ragi in Karnataka. The results shown that, TFP for ragi increased from 1.17 during 1999 to 1.81 in 2013. The TFP fell to 0.61 in 2011 and 0.67 in 2008 due to drought during that period. The highest TFP index was observed in 2007-08 (2.18). The average TFP index for 15 years was 1.12.The output index of ragi increased from 1.40 in 1999 to 1.79 in 2013. The average input index of ragi was 1.14 for fifteen years.Suresh, K. 2013, conducted a study on Economic impact of public sector agricultural research in ragi and redgram in Karnataka. The results revealed that, the Total Factor Productivity index of redgram grew at the rate of 3.31 per cent per annum and that of ragi grew at 4.75 per cent per annum. Thus, Public research significantly contributed to TFP growth in ragi.ConclusionTotal factor productivity can be estimated by different approaches. In growth accounting approach the tornqvist-thiel index is commonly used which is based on translog production function. The TFP decomposition analysis helps to identify factors which influence the total factor productivity growth. The results of the decomposition analysis indicate which variable contribute to growth in productivity. This will enable policy makers to suggest plan and programmes to achieve total factor productivity growth.
Download or read book Efficiency Differentials in Peasant Agriculture and Their Implications for Development Policies written by Kenneth H. Shapiro and published by . This book was released on 1976 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the theoretical and empirical work on allocative efficiency in traditional agriculture and presents a new study of technical efficiency among Tanzanian cotton farmers. The theoretical arguments are shown to apply primarily in a competitive context that differs significantly from that in which peasant farms operate. Reanalysis of earlier empirical studies shows that, on average, the marginal value products of inputs differ by more than 40 percent from the marginal factor costs to which they should be equated under allocative efficiency. Our own study among Tanzanian cotton farmers in Geita District reveals that output could be increased by 51 percent if all farmers achieved those levels of technical efficiency that were in fact achieved by the best farmers in the sample using the same inputs and technologies that the less efficient used. These results indicate that the efficiency hypothesis may not be applicable to much of peasant agriculture and that development policies might fruitfully place more emphasis on raising large numbers of farmers closer to the relatively high efficiency levels achieved by some of their neighbors.

Available in PDF, EPUB and Kindle. Book excerpt: Modern textbook presentations of production economics typically treat producers as successful optimizers. Conventional econometric practice has generally followed this paradigm, and least squares based regression techniques have been used to estimate production, cost, profit and other functions. In such a framework deviations from maximum output, from minimum cost and cost minimizing input demands, and from maximum profit and profit maximizing output supplies and input demands, are attributed exclusively to random statistical noise. However casual empiricism and the business press both make persuasive cases for the argument that, although producers may indeed attempt to optimize, they do not always succeed. This book develops econometric techniques for the estimation of production, cost and profit frontiers, and for the estimation of the technical and economic efficiency with which producers approach these frontiers. Since these frontiers envelop rather than intersect the data, and since the authors continue to maintain the traditional econometric belief in the presence of external forces contributing to random statistical noise, the work is titled Stochastic Frontier Analysis.
