Briefly explain the term pyramid in the context of corporate control?

In a pyramid structure, corporate control is exercised through a sequence of controlling positions in several layers of companies. The actual operating companies are at the bottom of the pyramid. Above each operating company is a first holding company, then a second holding company, and so on. Pyramids are common in Asian countries as well as in several European countries.

Under which circumstances would a conglomerate be effective?

Answer: Generally, conglomerates perform well in less-developed countries and also in countries where the legal system is based on civil law systems. Conglomerates can do well where financial markets are limited, and investor protection is poor, thus internal diversification can provide a service unavailable to external investors. The larger size of conglomerates can help in countries where political influence is important and where the larger size helps a firm gain access to international financial markets.
