In the Black & Scholes formula it is assumed that the volatility is constant. However, using historical option prices one can uniquely solve for the implied volatility. The implied volatility can then be used in the Black & Scholes formula to retrieve the market prices. In practice, options with the same underlying asset but different strikes/maturities require different implied volatilities. This is inconsistent since the implied volatility should not depend on the specifications of the contract. Thus the implied volatility is a function of the strike price. The plot of the implied volatility against the strike price is often refered to as volatility smile or market skew.
Policy competition for attracting foreign direct investment (hereafter FDI) has become commonplace in the past twenty years. For instance, in 2007, Texas Instruments Inc. announced its intention of establishing an assembly plant with an investment of $1 billion in Asia. Competition for this investment was fierce among Thailand, Vietnam, China and the Philippines. China and the Philippines comprised the final shortlist, and the Philippines beat out China for the site of the plant. Though it is not clear what tax breaks or other incentives the Philippine government may have offered Texas Instruments, the new facility is located in a special economic zone, which typically does provide considerable investment incentives. In March 2007, Intel Corp. announced in Beijing that it would build a $2.5 billion chip-fabrication plant in Dalian, China. CEO Paul Otellini said Intel’s choice of China for the plant reflects in part the advantages of building such facilities in places that offer better financial incentives than the U.S. does. Mr. Otellini cited testimony that he gave before a U.S. government panel in 2005 estimating that, because the U.S. offers less-favorable tax breaks and incentives, it costs $1 billion more to build a fab in the U.S. than elsewhere.
Other cases involve central-European transition economies. By the end of 1998, they all have adopted investment incentives to attract foreign investors. A typical incentive package contains exemption or significant reduction of income tax up to 10 years, grants for retraining of labor force or other subsidies. Such a policy proved to be successful and really increased the inflow of FDI to these countries. In particular, Poland ranked fifth place in the table, “Top 15 locations for FDI in Europe by number of FDI projects in 2008”; while it ranked second place in the table, “Top 15 locations for FDI job creation in Europe in 2008”.
The Venezuelan economy has grown more than 94 percent since the current expansion began in the second quarter of 2003.
1. he overwhelming bulk of this growth has been in the non-oil sector.
2. Throughout most of these five and a half years of unprecedented growth, the economy has often been characterized as an “oil boom about to go bust,” and predictions of collapse have been commonplace and often repeated. These have become more numerous of late since oil prices have fallen nearly 50 percent from a peak of over $130 in July to their current $64.48 per barrel.
3. The current financial crisis, worldwide stock market collapse, and recession in the United States, Europe, and Japan have also added to gloomy predictions for the region, including Venezuela.
