Various business support programs have been implemented in many countries across the world. Grants, interest-rate subsidies, and equity participation are among some of the most adopted tools for promoting firms’ performances (Dupont and Martin, 2006). Such assistance programs also have their own objectives. For example, low-interest rate loans and cash transfers to new and small firms are designed to overcome the financial constraints many firms face (Hubbard, 1998).

Nobel-winning economist James Heckman proclaimed that “the data speak for itself” after he carried out an experiment known as the 'Perry pre-School Project' and discovered that investing in high-quality preschool education brings returns of around 14 percent – a rate of return that is much higher than standard returns on stock market equity (7.2 percent).

Regional development policy, defined as aid and assistance given to economically less developed regions, is an issue for almost every country that seeks territorial unity. Putting the arguments of equity or efficiency aside, states with high regional disparities are potentially exposed to the political risk of disintegration.
