Discuss frameworks such as economic growth theory in relation to infrastructure investments and sustainability theories focused on reducing CO₂ emissions.

I would like you to write a comprehensive literature review (3000-4000 words) for my dissertation, which focuses on evaluating the efficiency of transport infrastructure investments across OECD countries using Data Envelopment Analysis (DEA). The review should include the following sections: Basic Concepts and Definitions:Define transport infrastructure, its economic significance, and its role in sustainability goals, especially in the context of OECD countries. Include definitions of efficiency in public investments, and introduce the concept of DEA. Theoretical Foundation:Explore the theories underpinning transport infrastructure’s impact on economic development and environmental sustainability. Discuss frameworks such as economic growth theory in relation to infrastructure investments and sustainability theories focused on reducing CO₂ emissions. Prior Studies:Provide an overview of relevant research that evaluates transport infrastructure efficiency in OECD countries. Discuss previous DEA applications in transport studies, emphasizing both CRS (Constant Returns to Scale) and VRS (Variable Returns to Scale) models. Include studies that explore both input- and output-oriented DEA approaches. Theoretical Framework:Introduce the DEA methodology as the theoretical framework for your dissertation. Explain why DEA is suitable for evaluating transport infrastructure investment efficiency, particularly in balancing economic growth and environmental sustainability across OECD countries. Research Gaps:Identify gaps in the existing literature. Discuss areas where previous research has not fully explored the interplay between economic growth and sustainability in OECD countries’ transport sectors. Highlight gaps related to the efficiency of public investments and the integration of environmental goals. Relevant Theories and Frameworks:Discuss any other relevant theories, such as public investment efficiency and the environmental impact of transport infrastructure, which support your dissertation’s aim to optimize transport investments for both economic and environmental goals. And other points deemed relevant and important.
