is taking place this weekend in Indonesia's capital, Jakarta.IHS Global Insight studies economic conditions around the world.The company believes that, in two years,Indonesia will become Asia's latest trillion-dollar economy.Its reason: a jump in the gross domestic product or GDP,the total value of goods and services produced within a country.IHS Global Insight predicts that by 2023,Indonesia's GDP will double to two trillion dollars.It also thinks Indonesia's GDPwill rise to three trillion dollars by 2028.The company expects Indonesia will have a largergross domestic product than Russia by 2021.It says Indonesia's expanding middle classwill make the country the largest marketfor consumer goods in the Association of Southeast Asian Nations.IHS Global Insight chief economist Rajiv Biswas spokewith VOA's Victor Beattie about Indonesian President Joko Widodo,also known as Jokowi.Mr. Biswas noted how the president launched a major programto improve his country's power supplies, roads and other infrastructure."That has been very much part of his election platform,and in his early months of office,it's clear that he has a strong focus on that.And that is something that Indonesia very much needs.Indonesia is one of the Asian economiesthat is relatively underdeveloped in terms of infrastructure."Rajiv Biswas says the spending on ports, roads and public serviceswill help to fuel Indonesia's economic growth.The current growth rate is five percent a year.But it was about six and one-half percent a few years ago.Mr. Biswas says the government debt to GDP rateis low for Indonesia when compared to past rates.He says the former government did a very good jobin reducing government debt levels.Early in his administration, President Joko Widodoannounced cuts in government fuel subsidies.For years the Indonesian governmenthad used public spending to keep fuel prices low.The decision to cut subsidies was unpopular,but Rajiv Biswas says, it helped the economy."The fuel subsidy reform was very, very importantbecause it was a heavy drain on their government expenditurein a rather unproductive formof just giving fuel subsidies to the entire population ...They will also be able to divert a lot of that moneythat would have been spending on fuel subsidies,towards infrastructure development,which is much more productive in the long-term for the economy."Rajiv Biswas says automobile sales have jumpedover the past five to seven yearsbecause of a rise in pay among Indonesia's middle class.He expects to see a pick-up in auto salesif the economy can grow at a rate of six to seven percent a year.He adds that Indonesia still rates lowon the World Bank's Ease of Doing Business Index.He says the country needs to increase manufacturing exports and create jobs.IHS Global Insight reports that more than two million young peopleare joining the Indonesian labor force each year.It says continued job growth is necessary to avoid the risk of social unrest.Yet the company estimates total per person GDP in Indonesiawill rise from $3,400 this year to around $8,700 by 2025.It says this might give the Indonesian government a greater voicein international financial organizationsand possibly the group of five nations known as BRICS.The five are Brazil, Russia, India, China and South Africa..
