I am not sure, but, could the same capital be counted many times? Say you have a holding structure with company A0 owning company A1, A1 owning A2 and so on. While the assets of A0 are the shares to A1, the assets of A1 are the shares to A2 and so on. This way the same capital is counted in company A0, A1, A2, and so on.
Given the complexity of property structure, and the speed of transactions, i am not sure how valid is the sum of equity positions in the determination of total capital value.
I am happy that someone has already asked this question long time ago. I have encountered the same problem in dealing with data from Penn World Table 9.1. Capital stock which is reported as RN_NA (real capital stock at the national price) and is way much higher than real gdp reported as RGDP_NA for many countries.
Yes, the amount of capital in the country should exceed the level of GDP many times and it usually is. On the other hand, however, in recent years, in some countries, public finances have been increasingly burdened with increasing public debt. In such a situation, the possibilities of financing new pro-development economic enterprises financed by the state may gradually decrease as the state's public debt increases.
