The Quiet Engine of Growth
This open access book demonstrates that in a large and diverse country like Indonesia, sustained national growth is difficult to achieve without accelerating the growth of its lagging regions. Conventional economic prescriptions—monetary and fiscal stimulus, trade liberalization, and deregulation of the real sector—are insufficient on their own. When national growth rises because lagging regions catch up, the result is an inclusive growth trajectory.
Yet even this is not enough. Higher output does not automatically translate into improved human welfare across regions. A welfare indicator such as the Human Capital Index (HCI) offers a far more meaningful measure than GDP because it captures both the current and future productivity of people. Ultimately, development is not defined by what a country produces, but by what its people become.
Using a spatial modeling framework and panel data, the book identifies the key determinants of regional HCI—education, stunting rates, and the dominance of the mining sector. It further argues that because the majority of Indonesian workers are concentrated in the low productivity retail trade sector, any policy seeking to raise welfare at scale must begin by improving productivity in this sector. This is not a peripheral concern; it is a central condition for broad based welfare gains, with the potential to transform the ordinary backbone of the economy into an engine of shared human advancement.
