Trust is really the crux of the matter. Economy is called the dismal science because it pretends to be one, disguising its uncertainties and shifting fashions with mathematical formulae. Economy describes the aggregate behaviour of humans and, in this restricted sense, it is a branch of psychology. People operate within a marketplace and attach values to their goods and services and to their inputs (work, capital, natural endowments) through the price mechanism. This elaborate construct, however, depends greatly on trust. If people were not to trust each other and/or the economic framework (within which they interact) - economic activities would have gradually ground to a halt. A clear inverse relationship exists between the general trust level and the level of economic activity. There are four major types of trust: a. Trust related to Intent - the market players assume that other players are (generally) rational, that they have intentions, that these intentions conform to the maximization of benefits and that people are likely to act on their intentions; b. Trust related to Liquidity - the market players assume that other players possess or have access, or will possess, or will have access to the liquid means needed in order to materialize their intentions and that - barring force majeure - this liquidity is the driving force behind the formation of these intentions. People in possession of liquidity wish to maximize the returns on their money and are driven to economically transact; c. Trust related to knowledge and ability - the market players assume that other players possess or have access to, or will possess, or will have access to the know-how, technology and intellectual property and wherewithal necessary to materialize their intention (and, by implication, the transactions that they enter into). Another assumption is that all the players are "enabled": physically, mentally, legally and financially available and capable to perform their parts as agreed between the players in each and every particular transaction. A hidden assumption is that the players evaluate themselves properly: that they know their strengths and weaknesses, that they have a balanced picture of themselves and realistic set of expectations, self-esteem and self-confidence to support that worldview (including a matching track record). Some allowance is made for "game theory" tactics: exaggeration, disinformation, even outright deception - but this allowance should not overshadow the merits of the transaction and its inherent sincerity;
