The Cost of Wind: Negative Economic Effects of Global Wind Energy Development

This paper provides a structured literature review of the negative economic effects associated with the development of wind energy and synthesized the evidence at an abstract level. We then developed an analytical framework to systematically review economic issues such as volatility, electricity price, housing values, and unemployment in relation to wind energy. Global wind energy development data from the time period from 2000 through 2019 were included for a more robust analysis. This period encompasses the vast majority of total global installed wind energy capacity. After amalgamating evidence from existing studies and data banks, we discuss the policy implications, suggest avenues for future research, and propose solutions to mitigate externalities. By understanding the negative economic impact created by the expansion of wind energy, we can better equip policy makers and developers to create more efficient and sustainable energy policy to benefit citizens and preserve the environment for generations to come

Innovation Types and Productivity Growth: Evidence from Korean Manufacturing Firms

The purpose of this paper is to investigate productivity growth according to three types of innovation: product innovation, product improvement, and process innovation, using firm-level data from the Korea Innovation Survey 2002 about Korean manufacturing companies. This study is conducted in two steps. The first step measures firm-level Malmquist productivity index by data envelopment analysis (DEA). The second step estimates econometric regression models by weighted least square utilizing the productivity index as a dependent variable and each of the innovation types and other characteristics of firms as independent variables. The empirical results partly support the idea that the types of innovation matter in productivity growth. Specifically, process innovation may result in higher productivity performance than product innovation in the short run. This result stems from the difference in efficiency growth when productivity growth is decomposed into two components: efficiency growth and technical growth. That is, product innovation by definition involves product development and radical innovation and so, it can deteriorate efficiency growth relative to other types of innovation due to the process of product development and the adjustments that are needed to new innovations whereas process innovation is implemented to reduce defects, lead time, costs and other factors, and as such is very efficiency orientated. Consequently it helps improve efficiency growth.Productivity growth, innovation types, product innovation, process innovation, product improvement,
