The US is facing a new pattern of demographic changes and their impact on Medicare and Social Security programs. The number of people on Medicare will grow in 2 decades, 2010- 2030, from 47 million to 80 million for Medicare, and from 44 million to 73 million for Social Security, according to this estimate. The workforce will grow more slowly and the tax base wiill shrink accordingly during this period. This pending worker-pensioner imbalance and the jump in the cost of the bill for Medicare and Medicaid, as well as the federal health benefit for poor people, create a major problem for the US. At the same time the group of people over 65 will rise in these 2 decades from 17% of the voting age population to 26%. This group and the people who expect to soon join this group will resist any changes to Medicare or Social Security programs, making it that much harder for the political process to tackle these issues to make the programs sustainable in the long run.

There is deep distrust of the Japanese government on the safety of nuclear reactors and a sense that the regulatory system has failed. In the most recent development, Osaka's mayor Toru Hashimoto, is withholding local approval for starting up 2 nuclear reactors at the Ohi plant, near Osaka. The 2 reactors passed simulated stress tests and were expected to be up and running, but public mistrust of the tests led to Hashimoto holding back on approval. Hashimoto was able to do this because Osaka is the largest shareholder in Kansai Electric Power. Hashimoto says he not against nuclear power, but against the top down regulatory system which works closley with power plant companies to protect their interests, with very little transparency on decisions and methods.

Vanguard Index funds attracted $233 billion in new investment in 2014, according to Morningstar. Of this $40 billion went into the Vanguard Total Stock Market Index Fund, $27.5 billion into the Vanguard Total Bond Market Index Fund, and $9 billion into the Vanguard Total International Bond Market Index Fund. The poorer returns from actively managed funds with high fees and the PIMCO Total Return Fund led to this shift into index funds. For every $100 in investment with Vanguard index funds the cost in fees is about 18 cents compared to $1.24 in the average actively managed mutual fund, according to Morningstar.

Using caution with bubble type internet stocks, stocks with no profits, real estate with large price jumps is suggested by experts. Models and methods have been developed to detect bubble type activity. Sornette at the Financial Crisis Laboratory, Swiss Federal Institute of Technology and the Bank of Finland's Taipalus have developed models to detect bubbles, including the bubble activity in internet IPO's and stocks in 2014. Chancellor at Boston asset manager GMO and Utkus at the Vanguard Center of Retirement Research have also come up with methods to detect bubble activity. Utkus says investors could reduce allocation by 10-20% in the case of stocks with bubble activity. Investors were doing this by reallocating in April 2014 from biotech and internet stocks to safer large cap stocks, because internet and biotech stocks had seen sharp increases of over 25% in a short period.

Microsoft shares were up 7% after the announcement about the departure of Steve Ballmer from the CEO position. Steve Ballmer became president in 1998 to run Microsoft's operations. He was a college buddy of Microsoft founder Bill Gates at Harvard. Ballmer graduated from Harvard with a degree in mathematics and economics and worked for 2 years at P&G before Gates persuaded him to join him at Microsoft. For decades the duo of Gates and Ballmer ran the company till Ballmer was made CEO in 2000. Ballmer completes three decades at Microsoft. During most of this period Ballmer focussed on protecting the existing franchise of Windows operating systems software and the Office suite sold on all PC's except Apple Macs. Missteps include Windows Vista, which was followed by the more successful Windows 7. Windows 8 has failed to make a significant dent in the market. A poor decision in retrospect to acquire Yahoo for about $44 billion did not happen, as Yahoo did not pursue discussions. The efforts in smartphones with Nokia and the Surface tablet have failed to produce results. Under Ballmer Microsoft only gradually shifted to cloud computing. The departure of Ballmer comes as a major reorganization was underway in 2013, and the company was shifting its strategy to become a provider of devices and services in place of its main role making software sales for PC's....

Prakash and Ghosh in the Hindusthan Times remind readers that even though India has ambitious plans for renewable energy much remains to be done in shifting to clean coal technologies. An estimated 80% of India's coal plants use obsolete technologies, making this an obvious area for improvement. India plans to make solar the source of 100GW of 175GW it plans to generate in renewable energy by 2022. Yet it must not be forgotten that coal is a dominant source for the foreseeable future and shifting to clean coal technologies is an area that should get top priority from the government. Today India is the third largest in terms of carbon emissions after the U.S and China.
