We highlight the strong connection between developing fully-funded, individually-owned, collectively-managed, mandatory/incentivized (FICMI) pension schemes and the development of domestic stock markets. We do so by building a stylized model and complementing the analysis with cross-country empirical analysis and case studies. We also highlight the challenges of individual impatience, network externalities, and coordination failure in long-term equity investments, which are crucial for stock market development and technological innovation. We find that FICMI pension schemes—when sufficiently wide in coverage and large in size—can serve as coordination devices to support long-term equity investments. Such investments will not only promote domestic stock market development and make it easier for firms to raise long-term equity capital, therefore supporting long-term economic growth, but also enhance financial inclusion and enable more households to benefit from the overall economic development, therefore contributing to inclusive growth. Moreover, we find that the introduction of FICMI pension schemes can impact household savings in two ways: first, FICMI pension can increase household savings through “forced/incentivized” savings channel, where households save too little without FICMI pension (such as in many EMDEs); and second, FICMI pension can decrease household savings and increase household consumption by reducing non-pension savings and decreasing precautionary savings, where households save too much without FICMI pension (such as in China). In both cases, FICMI pension schemes can help move the economy closer to the optimal level of household savings, and may also help improve the structure of such savings. Finally, we discuss the enabling conditions (such as a strong political commitment to the reform and a well-designed fiscal strategy for financing the transition) and policy design for FICMI pension schemes.
