Araise in the price of a product causes a decrease in competition an increase in competition a decrease in supply an increase in demand

i Believe the answer is: an increase in competition

The price of a product increase, the margin of profit that the sellers could get by selling the product would also be increased. Because of this, many of the sellers would be interested in marketing that type of product, resulting in an increase in number of competition.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
