Answer:
A teacher is a beautiful gift given by god because god is a creator of the whole world and a teacher is a creator of a whole nation. A teacher is such an important creature in the life of a student, who through his knowledge, patience and love gives a strong shape to student's whole life.
If an industry is perfectly competitive or monopolistically competitive, then the government has relatively little reason for concern about <span>the extent of competition. In a monopolistically </span>competitive market, products are differentiated by brand and quality but are not perfect substitutes due to this. Perfect competition is basically a theoretical market because the criteria to qualify has a perfect competitive market is hard to meet. The firms all set the price of their product and the market does not have any influence over it.
<span>The correct answer is that it depends on the specifics of the incentive plan. A general incentive plan that is not linked directly to productivity will typically become old news to staff within a few years. What was once an incentive will become familiar and may be viewed as an entitlement as staff start looking for the eternal "what's next?".
An incentive directly linked to some kind of productivity (e.g. hours worked) will have a far longer shelf life (though this will, of course, vary by employee). In this scenario the ongoing incentive remains year over year (e.g. the hours of overtime worked in the previous year will have no bearing on the current year so if you want a similar result you will need to maintain your effort whereas if you want a better result you will have to increase your effort).
All incentive plans, however, are subject to the rules of diminishing marginal utility to the employees and will diminish over time as the employee either becomes comfortable at a certain productivity level or becomes disenchanted by other factors.
In summation: an incentive plan, if designed properly, can work for a relatively long period of years though results may vary by employee as everyone is motivated by different things (though providing an alternative incentive to money may somewhat mitigate this additional potential problem).</span>
