Market failure arises because it is not possible for the market to correctly weight cost and benefits in a situation in which some of the cost is completely unaccounted.

Demand-side market failures happen when demand curves do not reflect consumer’s full willingness to pay for goods or services.

Supply-side market failures occur when supply curves do not reflect the full cost of producing a good or services.

A blocking assignment is one in which the statements are executed sequentially, i.e., first statement is executed and variable is assigned  a value then second is executed and so on. A non blocking assignment is  one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit.

e.g.

initial

begin

a=b; //blocking

c<=a; //nonblocking

d=c; // blocking

end

In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement. the second and the third statements are executed simultaneously, i.e. value a ais assigned to c and previous value if c is assigned to d.
