Efficiency Of Construction Contract Research

The market economy manifests contracts of a document of entitlement of exchange between the involved parties, with no exception to construction project contracts. Initially, disputes and problems in terms of tendering and bidding, illegal subcontracting, payment, time and quality, seem to be external influence factors to deter contract performance, but actually they are inherently a contract by themselves. Construction contracts are an incomplete deferrable contract that introduces heaps of uncertainties and risks. These uncertainties and risks might probably produce innumerable results among which the contract efficient result is expected.Both Employer and Contractor are supposed to be self-interested opportunists by the "contractual man" hypothesis. The construction contract proves to be a Pareto improvement to encourage their cooperation, but it does not necessarily lead to a social efficiency. It is contract efficiency that attempts to combine the individual Pareto efficiency pursuit with the social efficiency into a Kaldor-Hicks efficiency, in purpose of achieving a possible public-interested improvement in the presence of individual limited rationality.This paper employs the theory of economic analysis of law, and builds itself on the philosophy framework of pragmatism, the economic man doctrine and the jurisprudent values combined with efficiency and fairness. Methodologically it succeeds to individualism in the normative and empirical studies on the efficiency theory, risk allocation, efficiency obstacles, contractual norm selection and efficiency remedy. It is believed that the contract efficiency meets the self-interested motivation of Employer and Contractor, as well as the economic requirement of cost minimization. The incompleteness of construction contracts determines that contractual rules have an effect on contractual resource allocating efficiency, and they are conducted by risk allocation. Accordingly, the core economics of construction contracts is defined as the efficient allocation of construction risks, which is expected to carry a sharing base of constructing tasks, risks and incentives. Although efficient risk allocation is capable of obtaining an entirety of incomplete contracts, the market structure, information asymmetry and externality can be transactional cost deterrence to construction contract efficiency. Meanwhile, it finds itself that construction contracts have a self-fulfilled mechanism by themselves, where reputation, industrial conventions and continuous cooperation prove themselves to be an implicit contract confine the opportunists' behavior to default rules.In addition, the cooperative contract norms can be of efficient value in respect to construction task contracting and pricing. Regarding to matrix-formed contracts, linear contracts and turnkey contracts, contracting flexibility, required information, contract incompleteness, contract price, Contractor's risk assumption and value engineering application increase accordingly, and conversely of management span and Employer's risk assumption. Team-based virtual structure is usually helpful to enhance contract efficiency as well. In contract pricing norms, design depth is found useful to distinguish and select among stipulated-sum contract, unit-price contract and cost-and-fee (CPF) contract, which provide different risk allocation combinations and motivations. Generally, stipulated contracts have the largest risk bear to Employer and the smallest to Contractor, but Employer has the smallest and Contractor the largest in cost-plus-fee contracts on the contrary, where contracting price corresponds to Contractor's risk. What's more, price-based contracts are highly simulative to Employer, and weak to Contractor, but cost-based contracts are high stimulus to both Employer and Contractor, especially CPF variations can supply different appropriate incentive structures. But practice permits combination of contracting and pricing norms in order to establish the most applicable contract norm, and usually the efficient solution is easily found. Where there is a contract, there is a contract gap. Contract gap arises from the incompleteness of construction contracts, and it is the cause to contract performing obstacles. Therefore, contract gap needs make-up to approach a possible efficient performance in a possibly lowest transaction cost. The make-up rules are efficient increasingly in sequence of negotiation, laws, conventions and judge's free appreciation, and there are two other make-up rules such as quasi-arbitrary and contract matrix. When one or two parties breach the contract, remedies as specific performance and compensation for damage are allowed to protect the injured, but compensation for damage proceeds to specific performance, and it requires by contract efficiency that expected loss compensation is preferable to trust compensation and opportunity cost compensation. Additionally force majeure and change of circumstances are consideration changes to the previous contract status, driving it from a deficient path to an efficient one.
