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....

The resignation of Jerry Yang, co-founder of Yahoo, from his positions at the company on Jan. 17, 2012. Yahoo hired a new CEO, Scott Thompson, from eBay's Pay Pal unit n 2011. Yang started Yahoo with David Filo. They setup "David & Jerry's Guide to the World Wide Web," a list of favorite websites, as computer science students at Stanford in 1995. What followed was a trajectory similiar to the one observed today for Facebook- by 1999 the company was valued at $120 billion in the dot com bubble. A decade later Google, a newcomer with a search algorithm, replaced Yahoo as the most widely used search engine. Yahoo and its peer site AOL from the 1990's never recovered from the technological change in the internet with broadband and a new generation of search engines. Yang holds a 3.8% stake in Yahoo. Yahoo has a 40% stake in Ali Baba, which was formed when Yahoo turned over its Chinese operations to Ali Baba in exchange for a large stake in operations. Yahoo is planning to sell its stake in Ali Baba....

Under the McConnell-Biden fiscal cliff deal of Jan. 1, 2013, $620 billion is raised for deficit reduction over 10 years. This is made up of $395 billion from raising the top marginal income tax rate to 39.6% from 35% for the top 1% of filers who make $450,000 for couples or 400,000 for singles. Raising the top rate on capital gains and dividends to 20% from 15% raises $55 billion. Limiting the personal exemption and itemized deductions on incomes over $250,000 is a key component as it raises $150 billion. This reduction of tax expenditures was recommended by Simpson-Bowles deficit commission and Republican advisor Martin Feldstein, with more money raised under their proposals than the current proposal which follows the Pease format. Under the Pease limits named after a Congressman who proposed this in the 1990's, 3% of the amount above the threshhold income is deducted from the total deductions. Feldstein's proposal limited deductions to 2% of adjusted gross income. Romney offered a plan to limit deductions to $25,000. Finally, increasing the estate tax to 40% from 35% raises $20 billion....

Winkler says the Autonomy acquisition could be a useful step in executing H-P CEO Apotheker's new strategy to focus on higher margin businesses, but it comes at an expensive price tag. H-P paid ten times expected revenue for Autonomy, or 20 times earnings before interest, taxes, depreciation and amortization. This is too much cash considering that the share price of H-P has dropped by half since February 2011.

This WSJ editorial in September 2014 says many of president Obama's statements and decisions on Obama healthcare legislation and implementation, Syria, NSA and privacy, the Middle East, Russia, showed poor judgement. It refers to a piece by Peter Baker in NYT where it is said that Obama mocked how people see him as too professorial, diffident, in a sarcastic statement. The problem says WSJ is that president Obama has poor judgement. Being academically credentialed and quick grasp of subject matter is not the same as having the ability to discern things, instinct and grasp of the essence of the matter. George Bush senior had a long resume and was academically credentialed. By comparison Truman had a short resume and was not academically credentialed or quick with data and analysis. He had something more essential and important- a discerning mind and grasp of the larger picture, as well as listening abilities for exceptional advisors such as General Marshall and Acheson he gathered around him....

China's current account surplus has declined to 2.8% of GDP for 2011 from about 10% in 2007, and will be around 2.3% of GDP in 2012, according to IMF estimates. The U.S. current account deficit is down to 3.1% of GDP from 5.1%. By controlling the exchange rate China was able to keep the competitiveness of its exports, resulting in a five fold increase in exports from 2000 to 2010, according to the IMF. The decline could be temporary say experts, as the the recession in Europe and the U.S. resulted in slowing exports, with its infrastructure buildup sucking in imports of machinery and other goods from the western countries at an accelerated pace with its 2009 stimulus measures. Another reason is that in the last decade China has developed its own high tech and other companies which will now increase exports. IMF forecasts show a pickup in China's trade surplus to 4.25% by 2017. This could be lower if the renminbi is allowed to appreciate. Estimates of appreciation of the renminbi are 8 percent in nominal terms since June 2010 against the dollar. Including inflation, which is higher in China, the renminbi has appreciated by 13% since June 2010. ...

Automobile parts imports into the U.S. have increased from $89 billion in 2008 to $138 billion in 2014, up from only $31.7 billion in 1990.

Researchers David Autor of the Massachusetts Institute of Technology, Gordon Hanson of the University of California, San Diego, and David Dorn of the Center for Monetary and Fiscal Studies in Madrid, in independent research, studied the impact of trade on 722 clusters of interrelated counties in the U.S. They focussed on the surge in Chinese imports and found a pattern. Counties with higher exposure to Chinese import growth showed higher unemployment and higher expenditures by the government for unemployment benefits, food stamps and disability benefits. Their calculations show the increased government payments amount to one to two thirds of the gains from trade with China. This does not include the losses suffered by people losing jobs who deplete savings as they look for new jobs. Hanson studied the effects of trade and Chinese imports in the 1990's and found the effects were relatively small. This time the effects are large and show counties that lacked local investments in industrial machinery and technologies in which China was still playing catchup such as Caterpillar in Peoria, Illinois, and Boeing in Everett, Washington, were most susceptible to higher jobless rates and in need of government support payments. Autor and Hanson found that from 2000-2007, communities in the 75th percentile- ones with greater exposure to Chinese import growth than 75% of all communities- saw a manufacturing jobless rate of about one-third more than communities in the 25th percentile. The government payments mean higher taxes or larger deficits are needed to support these communities, and long periods of unemployment reduce the incentive to work. Michael Spence, a Nobel prize winning economist from New York University, says the world has never seen such a rapid pace of growth as China experienced between 2000-2011, with rates approaching 12% in some years, making past experience and prevailing theories on trade an insufficient guide to what is happening....

Internet content and communications provider Yahoo, is losing ground. Compared to a 4% growth for the Internet overall, Yahoo's increase in unique vistors was 4%, according to comScore in the 4 months of 2010 to April. Total minutes dropped 11%, and page views dropped 13% in same period, compared to double digit increases for the Web. Yahoo CEO, Bartz, lacks a background in journalism and content development. And AOL is pursuing a similiar strategy. Yahoo agreed to acquire Associated Content which aggregates content from bloggers, and it is making trials with local content in Detroit and Cleveland for user engagement. Bartz plans to revamp the email interface. Analysts sense that the repair job will be tough for Bartz as Yahoo's image has suffered.
