ape yang baru aku belajar dalam mikro tengah-Nash Equilibrium

Named after mathematician JOHN NASH, and central to game theory, Nash equilibrium refers to a situation in which individuals participating in a game pursue the best possible strategy while possessing the knowledge of the strategies of other players.

It works on the premise that the player cannot improve his/her position given the other players' strategy.

Nash equilibrium is sometimes referred to as the non-co-operative equilibrium because each player chooses his/her own strategy believing it is the best one possible, without collusion, and without thinking about the interests of either his opponent or the society in which he/she lives.

Product Life-Cycle Theory

Long-term patterns of international trade are influenced by product innovation and subsequent diffusion.

A country that produces technically superior goods will sell these first to its domestic market, then to other technically advanced countries. In time, developing countries will import and later manufacture these goods, by which stage the original innovator will have produced new products.

On a smaller scale, individual products pass through distinct phases: after a period of research and development, and trial manufacture, there is a period of introduction characterized by slow growth and high development costs. This is followed by a period of growth as sales and profits rise. A phase of maturity and saturation is then experienced as sales level off and the first signs of decline occur. The final phase is decline, characterized by lower sales and reduced profits, and perhaps final disappearance from the market.

The duration of each stage of the cycle varies with the product and the type of management supporting it.
