The principal-agent problem The principal-agent problem describes a class of interactions between two parties to a contract, an agent and a principal. The legal origin of these terms suggests that the principal engages the agent to act on his(the principals) behalf. In economic applications, the agent is not necessarily an employe of the principal. In fact, which of two individuals is regarded as the agent and which as the principal depends on the nature of the incentive problem

Alexander Hamiton (1755~1804) Encarta Encyclopedia, Hulton Deutsch One of the boldest American political thinkers of his time. Hamilton developed the doctrine of implied powers, which supports liberal interpretation of the U.S Constitution. He also served as the nation's first secretary of the treasury

John Locke (1632.8.29~1704.10.28) The 17th century English philosopher John Locke developed theories of empiricism that emphasized the role of human experience in the pursuit of knowledge and truth. Many of Locke's political theories influenced the authors of the Encarta Encyclopedia

Modified atmosphere (MA)techniques for horticultural products are based on the principle that manipulating or controlling the composition of the surrounding atmosphere affects the metabolism of the packaged product. By creating favourable conditions, quality decay of the product can be inhibited. The different MA techniques come with different levels of control to realise and/or maintain the composition of the atmosphere around the product. Passive MA packaging(MAP)
