Companies enter into agreements with business partners, municipalities, customers, employees and shareholders. Some of these agreements are written in an explicit contract and signed by all participants. Others are implicit agreements that are made up of legal or ethical obligations for each party to assume certain responsibilities. Despite the popularity of implicit contract theory in the 1980s, the application of implicit contract theory in the labour economy has been declining since the 1990s. The theory has been replaced by the theory of research and matching to explain the imperfections of the labour market.

The relationship between an employer and an employee is generally implicit. Employers employ someone and expect them to perform duties in exchange for compensation. While companies sign a contract or papers to employees, the employment relationship can be separated from the company at any time, unless it is contrary to labour laws or discrimination. In a particular area, an implicit agreement usually gives way to an explicit contract when it has one.
The rationing of loans to the amount of loans is also called credit restriction. In recent years, many macroeconomists have been interested in corporate data and business behaviour. There is widespread evidence that credit restrictions can be important determinants of business growth and survival.   Many of these studies model credit limitation as a result of an optimal implied contract when asymmetrical information is available between the borrower and the lender.   Despite its declining popularity among labour economists, implicit contract theory still plays an important role in understanding the imperfections of the capital market. An explicit joint agreement is when a company signs a joint venture agreement or partnership with another company. The agreement outlines the financial roles and interests of each company. Sales and acquisitions of real estate generally include formal contracts. Companies sign explicit agreements with lenders to obtain financing. They also ask customers to sign orders to document an agreement to purchase goods or services. The best way to protect your business from lawsuits and unethical practices is to establish formal contracts for all major business transactions. The origins of the implicit contract theory lie in the belief that the wage and employment movements observed cannot be properly explained by a competitive cash market, where wages always correspond to the marginal product of labour and where the labour market is always in balance. In the context of the labour market, an implied contract is an employment contract between an employer and a worker that determines the work done by the worker and the wages that the employer will pay in other circumstances in the future. An implied contract can be an explicitly written document or a tacit agreement (some call the first an “explicit contract”). The contract is self-imposed, meaning that neither party would be prepared to violate the implied contract in the absence of external application, otherwise both parties would be less well off. The earliest studies on the application of implicit contract models in capital markets consider the existence of credit rationing as part of a risk-sharing relationship between a bank and its client: the bank is risk-neutral and the borrower is risk-averse, which allows them to benefit from a long-term relationship by transferring the interest rate risk from the borrower to the bank.
