TEORI PEREKONOMIAN DUA SEKTOR

2024

Abstract

The two-sector economy is a basic model in macroeconomic analysis that often ignores the role of government and the foreign sector. This raises the question of how effective this model is in explaining more complex economic dynamics and how the interaction between households and firms affects national income. This research uses library research method to find all information about the two-sector economy. This research discusses the theory of a two-sector economy, which involves the interaction between households as consumers and firms as producers. In this model, expenditure (E) consists of consumption (C) and investment (I), while income (Y) comes from consumption and savings (S). National income equilibrium is reached when savings are equal to investment. In addition, this study explains the circular flow of the economy, which shows how income flows between the two sectors. The concepts of marginal propensity to consume (MPC) and multiplier are also elaborated to illustrate the impact of investment changes on national income. Thus, while the two-sector economy provides important insights, the limitations of this model in considering external factors should be recognized for a more comprehensive analysis.
