Answer: The Demographic Transition Theory (DTT) is a widely accepted model in demography that describes population change over time, relating it to industrialization and modernization. It postulates that a nation's population will shift from a condition of high birth and death rates to one of low birth and death rates as it transitions from a pre-industrial to an industrialized economic system. This theory typically outlines four or five distinct stages of population growth. **Stage 1: High Stationary...

Answer: Dependency theory offers a critical perspective on global economic development, asserting that the underdevelopment of peripheral countries is not merely a stage to overcome but a direct consequence of the development and expansion of core capitalist nations. Its basic propositions challenge traditional modernization theories by arguing that external forces, particularly the historical legacy of colonialism and the ongoing structure of international capitalism, are primary determinants of a nati...

Answer: Share tenancy and fixed-rental system are two distinct land tenure arrangements differing in how risk and returns are shared. In a **share tenancy** system, the output from the land is divided between the landlord and the tenant according to a pre-agreed ratio, such as 50:50. The tenant typically provides labor and other inputs, while the landlord provides the land. This system offers some risk-sharing for the tenant, as both parties share the burden of a bad harvest. Conversely, a **fixed-ren...

Answer: The efficiency wage model proposes that paying workers above their market-clearing wage can be rational for firms as it enhances worker productivity and profitability. This challenges the traditional neo-classical view where wages are solely determined by supply and demand for labor. Key results of this model include a reduction in shirking, as a higher wage increases the opportunity cost of losing the job, motivating workers to exert more effort. In developing economies, it can lead to improve...

Answer: Goods can be distinguished based on two characteristics: excludability (can people be prevented from using the good?) and rivalrousness (does one person's consumption diminish another's ability to consume it?). This framework helps classify private goods, public goods, and common-pool resources. Private goods are both excludable and rivalrous. This means that it is possible to prevent individuals who do not pay for the good from consuming it, and one person's consumption of the good prevents an...

Answer: Development economics encompasses various models and concepts critical to understanding growth, migration, and long-term well-being. The Harris-Todaro model elucidates rural-urban migration patterns, while social capital highlights the importance of networks and trust in development. Sustainable development, a broader concept, emphasizes balancing current needs with the ability of future generations to meet theirs, integrating economic, social, and environmental considerations. (a) The Harris-T...
