The mechanism by which trifluoperazine (TFP) induces apoptosis and inhibits growth in human A549 lung adenocarcinoma cells has not been entirely elucidated. In the present study, we investigated the anticancer mechanism of TFP in vitro using the human A549 lung adenocarcinoma cell line. The results indicate that TFP significantly inhibited the proliferation of A549 cells in a dose- and time-dep...

In this paper we aim to measure and to explain the frontier total factor productivity (TFP) growth in Tunisia over the period 1983-1996. We do not measure TFP growth by the conventional Solow residual. Instead we define TFP growth as the shift of the economy's production frontier, which we obtain year by year by solving a linear program, a sort of aggregate DEA analysis. We then decompose this ...

This paper examines the empirical relationship between trade and total factor productivity (TFP) in South Africa. Using data on actual trade protection across different manufacturing sectors, it is shown that trade liberalization had a positive impact on TFP growth during the 1990s. In addition, time-series evidence on macro data supports a positive long-run relationship between TFP and opennes...

Railways were integral to the development of the Indian economy before World War I. In this paper, we present new estimates of total factor productivity (TFP) for railways from 1874 to 1912, which highlight the strong performance of this key industrial sector. We find railway-industry TFP growth to be substantial, averaging 2.5 percent per year and generating a 3 percent social savings for the ...

Based on a framework proposed by Battese and Coelli (1995), we estimated the stochastic frontier production function for four Chinese industries: building materials, chemicals, machinery and textiles during 1990–1994. The type of technological change is tested and total factor productivity (TFP) growth is calculated for each industry. We found no evidence of technological change in the building...

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...

Improving total factor productivity (TFP) promotes high-quality development. This study estimates the TFP of 284 cities in China for period 2006–18, and constructs a time-varying difference-in-differences (DID) model impact national development zones (DZs) on regional TFP. The findings are as follows: (1) although DZs improve economic performance, they have not created growth; (2) despite heter...

This paper assesses total factor productivity (TFP) growth in India, examines the sources of productivity growth, including public and private investment, and estimates the rates of return to public investments in agriculture. The results show that significant TFP growth in the Indian crops sector was produced by investments -primarily in research -but also in extension, markets, and irrigation...

Our paper analyzes the causal links between human capital accumulation and growth in total factor productivity (TFP). In particular, it tests the NelsonPhelps hypothesis that human capital is crucial in enabling the imitation of technologies developed at the frontier. To this end we calculate TFP for a sample of 86 heterogeneous countries over the period 1960-1990 and investigate whether there ...
