In economic terms, the difference between formal and informal sectors is a thing of regulation. The formal economy includes reported payroll items, income taxes, employee taxes and any other official economic factors. The formal sector is an increasingly complex system of economics that historically grew out of the informal sector. The informal sector refers to parts of the economy that are not
. taxed, regulated, monitored or included in the gross national product. Often times called "under the table," jobs in the informal sector are not reported to the government. Due to the fact that these jobs go unreported, they are unable to have taxes taken out. Such jobs are paid in cash and are often times less secure or stable due to the fact that they are not protected by government regulation. The informal sector also includes the "black market," which involves the unregulated trade of goods and services, which includes contraband. Though difficult to measure or define, the informal sector is an important element in the functioning of any country. Many developing countries have economies much more heavily based in the informal sector simply due to the fact that regulations, firms, taxes and other such structures have not yet been established. Governments tend to strive toward formalization for the sake of efficient international interaction, however the process is complicated and long-term. In order for a nation to shift from an economy that is heavily based on the informal sector towards an economy that is based primarily on the formal sector, the government of that nation would need to seek out the parts of the informal sector and shut them down. Due to the difficult nature of this process, poverty stricken nations find it virtually impossible to move towards a more formal sector economy to earn revenue for the nation.
