The demand for animal protein especially fish is expanding due to the population growth, increased incomes and changes in eating habits and life styles. The capture fisheries in Malaysia which supply over 70 % of the fish used for food are over-exploited, and the yield has become stagnant over the last decades and in some cases it has even declined. In addition, the balance of trade for the pas...

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

This study measures the impact of investment climate factors on the total factor productivity (TFP) of agricultural manufacturing firms in Hanoi, Vietnam. Endogeneity of the production function and of the investment climate variables is addressed by using econometric models, based on individual firm information, and by aggregating investment climate factors by various business lines. Specifical...

Nowadays, agricultural R&D provides new and developed technologies to create modern agricultural producing methods. During recent years, improving agricultural productivity is affected by not only domestic R&D investments but also foreign countries R&D investments. Nowadays, according to new growth models, R&D is the base of productivity. Recent economic theories consider agricultural research ...

This paper examines the extent to and the conditions under which resource misallocation negatively affects aggregate productivity in a model of heterogeneous firms to the highest degree. I analytically derive the minimum aggregate total factor productivity (TFP) under resource misallocation, when frictions are modeled as the taxes levied on a firm’s output, and the range of these taxes is provi...

f rom the viewpoint of economic theories, total factor productivity (tfp) is the most important component that leads to economic growth and development. the main purpose of this study was to evaluate the impact of knowledge-based economy on total factor productivity in the member countries of the middle east and north africa (mena) region. for this purpose, the panel data regression analysis ha...

A divisia index of total factor productivity (TFP) growth is calculated for each of 16 regulated local telephone companies operating in Tennessee over the years 1989 through 1993. Year over year changes in TFP, in Tornqvist form, yield a growth in total factor productivity estimate for each company. These growth rates, however, contain the effects of both scale and technical change. Using the m...

This paper is concerned with the estimation of total factor productivity (TFP) growth for the Iranian electric utilities during the period 1980-1993 on the basis of panel data. A translog cost function is used which accommodates firm - specific variability through a one - way error component model. The results show that the Iranian electricity supply industry experienced increasing returns to s...

In the production function approach, an accurate output gap assessment requires a careful evaluation of the total factor productivity (TFP) cycle. We build a common cycle model that links TFP to capacity utilization and we show that, in almost all of the preenlargement EU countries, using information about capacity utilization reduces both the total estimation error and the revisions in real-ti...
