(7) Derived demand:= this is a situation in which a commodity is wanted not for its immediate satisfaction because of the demand for another commodity.

Joint/com[limentary demand:

when two or more commodities are wanted to satisfy one want at the same time.

competive demand:= it is wanted to satisfy a want in place of another similar commodity.

Composite demand: it is when a commodity is wanted to satisfy different wants.

(8) under employment, frictional unemployment,structural unemployment,voluntary unemployment, seasonal unemployment.

Underemployment: potentialities of a worker are not fully utilized., frictional unemployment arises when people leave their present job with the hope of getting a new and better one but fail at that time.

structural unemployment arises as a result of slight changes in the industrial structure of a country.

Voluntary:= this occurs when people refuse to take up any paid employment.

Seasonal unemployment:= caused by seasonal changes that affect some types of work.

(10) Availability of natural resources,level of development, industrial development, working population, economic situation.

Availability of natural resources:= a country with abundant natural resources will experience increase in national income than a country with little or no resources.

level of technology: a higher technological development will improve or increase a national income.

Industrial development: the presence of industries or increased industrial activities can contribute positively to national income.

Working population: a country with high working population is likely to increase national income than a country with a little population.

Economic Situation: when the economic situation is stable, the national income will be stable.

(11a)Economic integration may be defined as a form of international co-operation among nations to foster their economic interest.

Customs union: custom union is an agreement among nations to eliminate trade barriers such as tariffs,quotas, et.c among them.

(3a) specialization is the act of individual or a firm of a country concentrating its resources and efforts in the production of relatively few commodities

(3b) Advantages: increase in production,time saving, large scale production Increase in production:

specialization leads to increase in production because the various experts along the production process work together to boost greater production.

Time saving: specialization helps to save time by reducing the time wasted in moving from one operation to another.

Large scale production: specialization leads to large scale production as a result of many.

Disadvantages: monotony or repletion, problem of mobility of labour

(i)monotomy or repetition: a worker performs the same job on daily basis, therefore the job becomes monotonous and boring.

(ii) problem of mobility of labour: the worker stays on a single job for a long time and this makes it difficult for him to move to other jobs.

(4)Factors: Capital: the larger, the capital, the bigger the size.

2. Type of production: either the production is primary or secondary, this cab be determine the size of a business uint

. 3. Market size: this determines whether a business unit will be large or small.

4. Number of working population: the number of workers in aa business unit determines the size of it.

(6a) A market economy is an economy which decisions regarding investments, production and distribution are based on supply and demand and the prices of goods and services determines in a free price system

(6b) features of market economy:


(2) competition


(4)less government intervention

(5) choice of production.Supply and demand: the larger the available the available supply of goods or services in relation to demand, determines the market economy Competition: a market economy encourages competition regardless the type of business you operate, you likely face competition.

Choice of production: business owners decides what to produce in market economy

(5)(i) inadequste labour force: the available labour force is groslly inadequate to manage the abundant resources

(ii) low level of production: level of manpower available production is generally low

(iII) low standard of living: due to inadequate labour force that would have promoted output, the standard of living will eventually fall

(iv) underutilization of infrastructure: pipe borne water, etc are grossly underutilized

(v)high taxation: the working population will be made to pay higher amount of tax to take care of thedependents.

(2)(a) Marginal propensity to consume(MPC)= changes in consumption/change inincome(40,000,000-25,000,000)/(125,000,000-105,000,000)= 15,000,000/20,000,000=0.75

(b) multiplier (k)= 1/(1-MPC)=1/(1-0.75)=1/0.25=4(C) change in y/change in investment expenditure= 1/(1-MPC), Change in income= change in investment/1-(1-0.75)=12,000,000/0.25= #48,000,0000
