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 ...

S100A4, a member of the S100 family of Ca(2+)-binding proteins, regulates carcinoma cell motility via interactions with myosin-IIA. Numerous studies indicate that S100A4 is not simply a marker for metastatic disease, but rather has a direct role in metastatic progression. These observations suggest that S100A4 is an excellent target for therapeutic intervention. Using a unique biosensor-based a...

This thesis consists of two self-contained empirical essays. Essay I investigates the impact of labor subsidies on TFP, and profit per employee is included as a second outcome. Coarsened exact matching (CEM) is performed on the key variables. After matching, a difference-indifference (DID) model is applied. The study shows that firms employing workers with wage subsidies experience negative and...

The genus Neisseria contains at least eight commensal and two pathogenic species. According to the Neisseria phylogenetic tree, commensals are basal to the pathogens. N. elongata, which is at the opposite end of the tree from N. gonorrhoeae, has been observed to be fimbriated, and these fimbriae are correlated with genetic competence in this organism. We tested the hypothesis that the fimbriae ...

By using the stochastic frontier methodology, this study investigates the technical efficiency and total factor productivity (TFP) growth in Indonesian provincial economies during the period from 1993 to 2000. In addition to the estimation of provincial technical efficiency, factors that contribute to technical inefficiency are also examined and the TFP growth is decomposed into technological p...

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...

The total factor productivity (TFP) of a multiple-output multiple-input firm can be defined as the ratio of an aggregate output to an aggregate input. With this definition, index numbers that measure changes in TFP can be expressed as the ratio of an output quantity index to an input quantity index. This paper uses the term multiplicatively complete to describe TFP index numbers that are constr...

Total Factor Productivity (TFP) accounts for a sizable proportion of the income differences across countries. Two challenges remain to researchers aiming to explain these differences: on the one hand, TFP growth is hard to measure empirically; on the other hand, model uncertainty hampers consensus on its key determinants. This paper combines a non-parametric measure of TFP growth with Bayesian ...

This study analyzed the productivity of Tuber crops in Nigeria from twenty states between the periods of 1995 -2006 using Data Envelopment Analysis (DEA) to estimate the total factor productivity (TFP) which was further decomposed to reveal the source of productivity growth over the reference period. Negative TFP growth was observed for all the tuber crops considered in the study on the average...

In this paper, a comparative analysis of growth in total factor productivity (TFP) in the formal and informal segments of Indian manufacturing industries is undertaken, along with an analysis of differences in the level of TFP between these two segments of Indian manufacturing. The period covered for the analysis of TFP growth is 1980-81 to 2011-12, which is broken into three-sub-periods, 1980-...
