ABC`s shares sell for $60, and a caller wants to sell calls for $65 for a month. If the share price stays below $65 and the options expire, the caller retains the shares and can collect an additional premium by re-depreciating the calls. Another common option agreement is the real estate market. The option agreement sets out the conditions under which a party has the right to acquire a property at a price determined at a later date. Both types of contracts are selling and calling options that can both be purchased to speculate on the direction of stocks or stock indices, or be sold to generate income. For stock options, a single contract includes 100 shares of the underlying stock. An option agreement is a legally binding contract between two companies, which outlines the responsibilities of each counterparty to the other company. In the economy, option contracts play an important role in the field of contract theory. In particular, Oliver Hart (1995, p. 90) has shown that option contracts can reduce the problem of the queue (a problem of underinvestment that arises when the exact amount of investment cannot be contractually fixed).  However, contract theory discusses the relevance of option contracts if the parties cannot rule out future renegotiations.  As Tirole (1999) pointed out, this debate is at the centre of discussions on the basis of incomplete contractual theory.
 In a laboratory experiment, Hoppe and Schmitz (2011) confirmed that non-negotiable option contracts can effectively solve the detention problem.  In addition, it appears that option contracts are still useful even if renegotiations cannot be ruled out. This latter observation can be explained by Hart and Moore`s (2008) idea that an important role of treaties is to serve as benchmarks.  Given the growing demand for land, many landowners are beginning to think about how they can make their country work for themselves, and an option agreement is one way to do so. The question of whether an option amount should be paid at the time of the exchange and, if so, the value of the option to be paid is being negotiated. Perhaps you would also like the country to be evaluated. They will want to pay as little as possible, but a seller will no doubt demand consideration for the option that limits the seller`s ability to manage the property during the option period. The general principle of contract law is that an offer cannot be entrusted to another party by the recipient of the offer.
However, an option contract may be sold (unless otherwise), allowing the option purchaser to put himself on the back of the original bidder and accept the offer to which the option relates.  An option contract is an agreement between two parties to facilitate a potential transaction of the underlying security at a pre-defined price, called strike price, before the expiry date. If the developer does not obtain the necessary building permit for the development of the land, it is unlikely that the developer will make use of the option and therefore the sale of the land will not continue. Option agreements allow developers to explore (and exclude) the possibility of acquiring land for potential development, without having to.
