This thesis presents three chapters on development dynamics involving market structures, geopolitics, and growth. Chapter 1 assesses China's cigarette market, suggesting price elasticity is low and increased tobacco taxes may not reduce smoking due to cultural and political factors. Chapter 2 evaluates the economic benefits of releasing Israeli-controlled Area C of the West Bank, estimating a potential $4.4 billion annual gain. Chapter 3 analyzes income patterns in post-colonial states, linking development to spatial scales and historical regimes, and highlighting the complex interplay between growth, geography, and colonial histories.
