This study applied the Cobb-Douglas production function to identify economics efficiency of 18agricultural product processing companies listed on the Stock exchange in Ho Chi Minh City(HOSE) and Hanoi (HNX) in such sectors as fisheries, rubber and sugar in the period 2009-2013.The method employed FEM and REM models using panel data. The results showed thatperformance of all and each sector in this study has increasing returns to scale. In particular,firms in the sectors of fisheries and rubber primarily relied on raising capital to increasetheiroutput value, while those in the sugar sectormainly increase labors toimprove theiroutput value. Finally, the paper also provides some policy implications to improve theefficiency of capital and labor in the agricultural product processing companies.

This paper considers an optimal endogenous growth model where the production function is assumed to exhibit increasing returns to scale and two types of resource (renewable and nonrenewable) are imperfect substitutes. Natural resources, labor, and physical capital are used in the final goods sector and in the accumulation of knowledge. Based on results in the calculus of variations, a direct proof of the existence of an optimal solution is provided. Analytical solutions for the planner case, balanced growth paths, and steady states are found for a specific CRRA utility and Cobb–Douglas production function. It is possible to have long-run growth where both energy resources are used simultaneously along the equilibrium path. As the law of motion of the technological change is not concave, reflecting the increasing returns to scale, so that the Arrow–Mangasarian sufficiency conditions do not apply, we provide a sufficient condition directly. Transitional dynamics to the steady state from the theoretical model are used to derive three convergence equations of output intensity growth rate, exhaustible resource growth rate, and renewable resource growth rate, which are tested based on OECD data on production and energy consumption.

The efficiency of the construction industry is analyzed based on provinces panel data in China in this paper. The Mean Number of Employee and the Mean Completed Investment are used as inputs. The Mean Actual Sales of Commercial Houses and the Mean Net Profit are used as outputs. Data Envelopment Analysis (DEA) model is used to measure the efficiency of the construction industry. Shanghai and Zhejiang are found technically efficient. Shandong is scale efficient but technology efficiency is lower. There are two provinces are decreasing returns to scale and other provinces are increasing returns to scale. On the whole, the technology efficiency of the construction industry of China is lower. Based on the conclusions, the paper proposes some suggestions to improve the efficiency of the construction industry in China.

This paper uses cross-sectional data from the 1993 Major League Baseball season to derive the production function for the industry. Using that function, the hypothesis that employee productivity drops in response to the job security of a multi-year contract is test ed by comparing the marginal products of players in the year preceding and the year following the signing of a multi-year contract. I find that the production function for Major League Baseball exhibits increasing returns to scale and, contrary to the popular belief of observers of the sport, hitting is more important to team success than pitching. I also find compelling, statistically significant evidence of worker disincentives associated with multi-year contracts.

Recent findings emphasise the importance of localised returns to scale for the regional growth as well as for the agglomeration processes. However, it is still not well established whether returns to scale are constant or increasing, and to what extent. Therefore, in this study we apply specification which describes the productivity growth with the growth of output through the Verdoorn’s law. This study aims to provide some new estimates of the degree of returns to scale for EU regions. Our findings show that the hypothesis of increasing returns to scale is still valid in today’s EU economy. To test the hypothesis, we have employed the Multidimensional Spatial Panel Durbin Model with Spatial Fixed Effects. The research is conducted for 261 regions of the EU 28. The paper concludes that increasing returns to scale in EU regions are substantial.

From the 1980s, network effects attracted a lot of interest in economics and management sciences. This was mainly due to the work of Arthur (e.g., 1988, 1989, 1990). While the subject of increasing returns to scale in companies had a long tradition in economics, network effects (i.e., increasing returns in markets) had hardly been addressed.
