This thesis contributes to understanding labor market frictions and how these frictions impact macroeconomic aggregates such as unemployment and productivity. It also critically examines environmental policies such as carbon taxes and green financing. The first chapter examines how non-compete contracts signed between employers and employees affect unemployment, productivity, and welfare in the economy. These contracts stipulate that the employee, while under contract, cannot work for a competing employer for a specified period, typically ranging from one to two years after separation from their initial employer. This type of contract is widespread in the United States and affects at least one in five employees in the country. Results show that a high enforceable incidence of these contracts can compress wages and generate unemployment. This is primarily due to the fact that some individuals who have signed such contracts face difficulties in finding new employment after separating from their initial job. The article proposes reducing the duration of the post-employment restrictions of these contracts to mitigate their effects on workers. However, it is worth noting that these contracts partially benefit employers by incentivizing them to invest in employee training, thereby increasing overall productivity. Speaking of employment contracts, the second chapter evaluates the implications of the coexistence of temporary contracts (fixed-term contracts) and permanent contracts (indefinite-term contracts) on worker flows between unemployment, employment, and labor force non-participation over the life-cycle. This analysis is particularly important due to the effects of these flows on aggregate employment and wages over the life-cycle. It is found that transitions of individuals from permanent employment to unemployment are the most significant factor explaining aggregate employment over the life-cycle. Any policy aimed at increasing employment should target this flow of workers. Moreover, the transition of individuals from temporary employment to unemployment is significant in explaining the low employment of young individuals in European countries like France, especially for those with higher levels of education. The article goes further by constructing a model that explains the observed transition profiles during agents' life-cycle and analyzes how the effects linked to employment protection reforms in European countries are distributed among workers based on their level of education and age. Finally, the third chapter provides a critical assessment of environmental policies such as emissions taxes on production units and green financing. The article shows that despite their effectiveness in reducing emissions, these policies can negatively impact resource allocation, such as capital, among firms, thus reducing aggregate productivity. This is because some highly productive but seriously financially constrained firms may struggle to invest in emission reduction technology, while less productive but wealthy entrepreneurs invest more easily. The burden of emissions-related fiscal measures forces the former to exit the market, thereby reducing productivity. This suggests that other policies, such as green subsidies, are important to mitigate these potential distortions.
