The main objectives of this paper are to assess the production costs and to measure the total factor productivity (TFP) of durum wheat production for a sample of cereal farmers in the North of Tunisia. Our hypothesis is that improvement of these indicators can reduce the production costs and consequently the improvement of producers' incomes. To test this hypothesis, a survey was carried out with 232 cereal farms in the subhumid region in the North of Tunisia cultivating durum wheat. The reconstituted costs approach was used to estimate the production costs. The results obtained show that total costs, production costs and net margins of durum wheat vary according to the farm size. About 67% of surveyed farms make a positive net margin. The empirical results of the regression reveal that productivity is negatively affected by the farm size, the new varieties demanding water and the investments made by the farm while it is affected positively by crop rotations

We measure the evolution of population, investment rates, and total factor productivity (TFP) for East Germany and West Germany around their 1990 reunification to create a model that allows us to consider the economic ramifications of a hypothetical reunification between South Korea and North Korea. The scenarios that we consider suggest that worker migration from the North, a decrease in investment, and a slowdown in TFP growth could exert a substantial negative and persistent effect on South Korea's economy although the North is predicted to benefit from more rapid income growth. We also summarize the economic and policy questions that our quantified model illuminates.

Recently, Penn World Tables include new data that enable calculation of total factor productivity in addition to output for a large set of countries. We use these new data to examine convergence and divergence across countries by applying a new approach, which differentiates between the dynamics of output and of productivity. Our empirical results lead to two main new contributions to the literature. The first is on the interpretation of “β-convergence” in “growth regressions.” It means that output per worker in each country converges to productivity but does not imply convergence across countries, since productivity tends to diverge from the global frontier. The second contribution is to the literature, which finds that income gaps across countries are due mainly to differential technology adoption. This paper shows that the gaps in technology are not only large but keep growing over time.

This paper was designed to capture the determinants of the agricultural total factor productivity (TFP) level across 60 provinces in Vietnam during the period 1990-2006. The TFP level in Tornqvist form was used to regress on 4 groups of determinants: omitted inputs of agricultural production process; quality of inputs used in agricultural production; technology factors; and output structure. The estimated results showed that: (i) Vietnam’s agricultural sector became relatively more capital intensive; (ii) South provinces were more productive, while North Midlands and Central Coast tended to lag further behind; (iii) labour mobility played a very important role in resources accumulation in agriculture in Vietnam, and so in improving TFP; and (iv) agricultural TFP was significantly influenced by land quality, farm size and land fragmentation.

The U.S. hog industry has experienced dramatic structural changes and rapid increases in farm productivity. A stochastic frontier analysis is used to measure hog enterprise total factor productivity (TFP) growth between 1992 and 2004 and to decompose this growth into technical change and changes in technical efficiency, scale efficiency, and allocative efficiency. Productivity gains over the 12-year period are found to be explained almost entirely by technical progress and by improvements in scale efficiency. Differences in TFP growth rates in the Southeast and Heartland regions were found to be explained primarily by differences in farm size growth rates.

This paper examines the determinants of total factor productivity (TFP) of Ukrainian firms in manufacturing and services, using micro-level data for the years 2005 and 2013. We first estimate regressions for the pooled dataset for the manufacturing and service sectors jointly, and then separately for each sector. Our empirical results show a positive link between the total factor productivity, intangible assets, capital intensity, firm size, competition in the industry, ownership status, and firm internationalization (exports and imports). In addition, we find that the determinants of productivity differ among the sectors and years of our sample.

Panel Vector Autoregression

A comparison between countries shows that there is a difference in terms of economic growth achievement across nations. This difference is due to the contribution of capital growth, labor, and total factor productivity (TFP). Although the use of capital and labor plays a vital role in the production, the contribution of TFP growth is also indispensable, as it saves production costs. Nevertheless, in 1995-2000, most countries have experienced a negative growth of TFP in which can affect its contribution to economic growth. Therefore, the focal point of this study is to analyze the impact of TFP growth shock on economic growth in selected ASEAN+3 countries (i.e., Malaysia, Singapore, Thailand, Indonesia, Philippines, Cambodia, Vietnam, China, South Korea, and Japan), using the data set from 1981 to 2014. The study employed the panel vector autoregression (PVAR) method in analyzing the propagation of the shocks through impulse response function and variance decomposition. The main findings revealed that TFP growth shocks have a positive impact on economic growth. Besides, the results also showed that over the next ten years, the proportion of human capital variation would be more dominant in contributing to the economic growth for the selected ASEAN+3 countries. As the surge in TFP growth had a positive impact on economic growth, this finding indicated that each country needs to allocate more expenditure in the Research and Development (R&D) activities.

The study dealt with the whole scenario of modern variety potato production in Bangladesh covering the period from 1980-81 to 2005-06. The study estimated the extent of shift of production function or the supply curve of modern variety of potato in Bangladesh. The total factor productivity index was estimated using the Tornqvist-Theil index formulation. The growth rate of area, production and yield were found increasing steadily from the year 1980-81. A substantial change has been started from the year 1998-99. The trend of inputs used was found increasing. Almost all the partial as well as the input, output and total factor productivity indices were also found increasing. It may be concluded that for sustaining the present growth of modern variety potato production, the development of new varieties of potato and extensive extension works are needed. Key words: Growth rate, partial factor productivity, total factor productivity, modern variety potato. DOI: 10.3329/jard.v7i1.4423 J Agric Rural Dev 7(1&2), 65-71, June 2009

This paper applies nonparametric superlative index techniques to measure productivity growth in the sawmilling industries of the United States and Canada. Six geographic regions are examined: British Columbia (Coast and Interior), Ontario, Quebec, U.S. South, and U.S. West. The results indicate significant adjustment of resources both within and across regional industries over time. Over the long-term, labor has been the input that has experienced the highest growth in productivity: 3–4% per annum in the commodity-oriented regions. This result likely reflects the significant increases in capital stock throughout most of the North American industry. From 1980 to 1988 there have been significant differences in the annualized growth rates in total factor productivity across regions: U.S. West (3.3%), B.C. Interior (2.7%), Quebec (1.9%), U.S. South (1.4%), B.C. Coast (1.3%), and Ontario (1.1%). However, growth in total factor productivity over the 24-year period from 1965 to 1988 is relatively uniform across most regions (1.2% per annum).

This paper documents large revisions in a widely-used series of utilization-adjusted total factor productivity (TFP) by Fernald (2014) and shows that these revisions can materially affect empirical results about the effects of news shocks. We trace these revisions to changes in estimated factor utilization that are evocative of cyclical measurement issues with productivity. We propose an alternative identification that is robust to these measurement issues. Applied to U.S. data, the shock predicts delayed productivity growth while simultaneously generating strong responses of novel indicators of technological innovation and forward-looking variables. The shock does not lead to comovement in macroeconomic aggregates.
