Paper: Opciones, un poco de historia

The Early History of Option Contracts

Abtract

This chapter discusses the history of option contracts from ancient times until the appearance of Theorie der Prämiengeschäfte by Vincenz Bronzin in 1908.  The history examines the use of contracts with option features prior to the introduction of trade in free standing option contracts on the Antwerp bourse during the 16 th century.  Descriptions of the Amsterdam share option market by de la Vega in the 17 th century and de Pinto in the 18 th century are reviewed.  The specific language of a late 17 th century English option contract is provided in detail.  The development and practice of option trading in the 18 th  and 19 th centuries, as reflected  in merchant manuals of that period, is examined.  The article concludes with an overview of late 19 th century option trading in securities and commodities.

Paper: Opciones sobre ETFs y Volatilidad Implicita

The Implied Volatility of ETF and Index Options

Abstract: 
We examine the option-implied volatility of the three most liquid ETFs (Diamonds, Spiders, and Cubes) and their respective tracking indices (Dow 30, S&P 500, and NASDAQ 100). We find that volatility smiles for ETF options are more pronounced than for index options, primarily because deep-in-themoney ETF options have considerably higher implied volatility than deep-in-the-money index options. The observed difference in implied volatility is not due to a difference between the realized return distributions of the underlying ETFs and indices. Differences in implied volatility for ETF and index options also do not appear to be explained by discrepancies in net buying pressure, as theorized by Bollen and Whaley (2004).

The BP Gulf Coast Oil Spill, Option Value, and the Of shore Drilling Debate

In the wake of recent unrest in the Middle East, rising gasoline prices have politicians from both parties  scrambling to ramp up domestic oil production. Perhaps ironically, this scramble coincides with the one  year anniversary of the BP Gulf Coast Oil Spill, the single largest of shore oil spill in history.
This regulatory report examines the economics of increased domestic oil drilling, in light of large uncertainties associated with this activity. Many of the most important factors for making smart choices about oil drilling are uncertain: future oil prices cannot be perfectly forecasted; science has a limited understanding of the scope and consequence of environmental damages from oil exploration, production, and accidents; and the rates of technological innovation for both production improvements and cleanup  technologies are dii cult to predict.
The primary finding of this report is that, unless uncertainty is incorporated into the economic models used to determine whether oil drilling is appropriate, the United States will allow too much drilling, too soon, and with too much risk. h is reality should be rel ected in how the Department of the Interior structures the sale of leases to extract of shore oil—but presently, it is not.
A major l aw with the rhetoric currently dominating both sides of the political debate over domestic oil drilling is the focus on gasoline prices. In fact, expanding domestic drilling will have practically no ef ect on, and so should not be motivated by, gasoline prices. Economic analysis of oil markets shows that expanding domestic oil production is “not likely [to] have a signii cant impact on prices that consumers pay at the gasoline pump now or in the future.” Because the United States is engaged in global oil markets, even relatively large domestic changes in production will be swallowed by the larger global supply and demand,  leading to only negligible changes in price.
If increasing domestic oil production is economically justifier, it will not be as an ef ective or ei cient  response to rising gasoline prices. Rather, the choice would only be justified because the benei ts of  drilling (namely, revenue from the operation) outweigh the costs (like the production costs and the risks  of environmental damage from accidents). Consequently, to make that choice, the full extent of both the benefits and costs of drilling must be examined.
