By reviewing and improving previous empirical works on this topic, the present paper investigates the dynamic externalities of agglomeration in China. Taking China’s top three municipalities (i.e., Beijing, Shanghai, and Tianjin) as sample regions, it assesses empirically and compares how three types of dynamic externalities—namely MAR (Marshall–Arrow–Romer), Jacobs, and Porter externalities—af...

Species richness generally promotes ecosystem productivity, although the shape of the relationship varies and remains the subject of debate. One reason for this uncertainty lies in the multitude of methodological approaches to sampling biodiversity and productivity, some of which can be subjective. Remote sensing offers new, objective ways of assessing productivity and biodiversity. In this stu...

We estimate who benefits from local productivity growth. We begin by using confidential plant-level data to calculate changes in manufacturing productivity by United States metropolitan areas (MSAs), and then predict changes in MSA productivity based on MSAs’ initial industry shares and subsequent national changes in productivity by industry. We find that local productivity growth benefits loca...

PURPOSE To explore whether there is a relationship between resilience and academic productivity of minority faculty members in U.S. academic health centers. For the purposes of the study, the authors defined academic productivity as peer-reviewed and non-peer-reviewed publications, grants, and academic promotion. METHOD In 2007, the authors simultaneously collected quantitative and qualitativ...

We highlight the difference between the service sector and the manufacturing sector in regard to the determinants for a firm to start FDI and the productivity growth it achieves. This paper analyzes two questions: (1) whether a certain level of productivity explains a Japanese firm’s choice to be a multinational firm (by starting FDI), and (2) how the productivity of such a multinational firm c...

This study was designed to determine the effect of multimodal intervention and the prevention of back injury, and to evaluate the adverse side effects of using a lumbosacral corset in the workplace. Subjects were 90 male warehouse workers randomly selected from over 800 employees at a grocery distribution center. Subjects were assigned to three groups: true controls, no back school, no brace or...

BACKGROUND Due to the increasing health care costs, the issue of productivity in hospitals must be taken into great consideration in order to provide, preserve and promote public health services. Thus, increasing the level of productivity must become the main aim of any hospital. Objective of this study is to determine the total factor productivity and its components over the period under the s...

The vast majority of regions in West Germany, and the EU, have become more similar in terms of per-capita income and productivity between 1980 and 2000. But a number of rich areas generally large agglomerations have succeeded in departing from this trend of convergence. They are continuing to rise above the average productivity level. We examine whether this development can also be seen as due ...

A key part of the uncertainty in terrestrial feedbacks on climate change is related to how and to what extent nitrogen (N) availability constrains the stimulation of terrestrial productivity by elevated CO2 (eCO2 ), and whether or not this constraint will become stronger over time. We explored the ecosystem-scale relationship between responses of plant productivity and N acquisition to eCO2 in ...

Journal: Iranian Economic Review 2019

he links among trade, technological changes, and worker earnings have been the subject of intense research during the past few decades. The current literature on this subject shows that trade liberalization and technological changes are the main drivers of demand for skilled workers and a rise in the wage premium. In the present article, a panel of 134 Iranian manufacturing industries over the ...
