However, there are drawbacks as well. Among the largest of these is the inability of the government to collect income taxes from the tens of thousands of small businesses in the informal economy. This means less money to provide public services, such as health and education. Moreover, most informal sector enterprises are beyond the reach of government regulators, so the gado-gado you buy off the street, while cheaper, is not subject to the same health codes and standards that govern restaurants. People working in the informal sector are affected as well; they typically have little or no job security, and regulations governing safety in the workplace are frequently ignored. And most of the positive aspects of the informal sector are negated if the informal sector functions as a final destination for laborers and entrepreneurs, rather than as a temporary "holding tank" until they find opportunities in the formal sector.
You can see the percentages for formal and informal sectors around the world on the map below. I took this from a site called "Mish's Global Economic Trend Analysis". It's the only map I could find without doing some scanning, so sorry about the superfluous notes.
It's traditionally been very difficult to get accurate statistics on the informal economy because of its under-the-table and off-the-record nature. However, it is generally accepted that more than 50% of the workforce in developing countries is employed in the informal sector. In some countries it can be as high as 90%. Compare this to 4-6% in wealthy countries and you have quite a contrast. Estimates for Indonesia are that 70% of the workforce is in the informal sector, with a higher proportion in the countryside compared to the cities (80% to 25%). There is also a gender component here; women are more likely to be engaged in informal employment than men (2:1), and they are also paid less. The large informal sector (and lack of information about it) makes it difficult to create policies to protect workers, provide services, and encourage economic development.
Recently I spent a day chatting with people employed in the informal sector around Jogjakarta. Though they all expressed the same concerns about healthcare, they seemed to appreciate the open nature of the informal economy. The tailor working at the stall in the picture to the right told me that in a day he and his partner make about 50,000 rupiah ($6 or so) which they split. He said he usually sleeps in the stall. He told me there are no regulations governing his business and that they don't pay taxes, so overhead is low. Also the machines they use are pedal-powered, so there is no electrical bill. He said that anyone could start up a business like this one. The drink vendor in the second picture to the right told me that he did a pretty good business because he has a regular clientele. He has two pushcarts; one he operates during the day in a business district, while at night he sells sweet drinks at the Alun-Alun, a large park area south in the Kraton where people congregate in the evening. He told me that it wasn't hard to start up a business, but he did have to be inspected periodically by the health department. He also told me that sometimes there can be fierce competition because so many people move to the city and start small businesses like his.
Household helpers (pembantu rumah) also form a significant part of informal employment here. However, they have different circumstances than the folks described above. In many cases the employer provides lodging and meals for the pembantu, but the pay is significantly lower. However, the employer also assumes some responsibility for the pembantu and has certain obligations, sometimes including providing education and money for the pembantu's family in case of emergency. And while can't state this as fact, it seems to me that there is an expectation that well-off people will employ household helpers, which provides jobs for a significant number of low-skilled people.
Anyway, that's a wrap for today.
(1) Some economists differentiate between the "informal sector" and "informal employment". The first term refers to businesses that are not formally registered with the government, whereas the second term refers to all the people that are employed on a "casual" basis. This includes people working for established companies without contracts and benefits.
(2) "Labor intensive" means that the production process relies more on human labor than machines.
