Public administration can be broadly described as activities of states or governments. There are lots of activities which you can imagine such as providing public services to citizens, produce laws including protecting you etc. Governments design their own administrations. They choose whatever approach appropriate: top-down, bottom-up or maybe other invented styles. In under developed countries, basically, governments exercise strong power to lower levels to ensure that everything is under regulations. This might follow a certain type of administration which is a bit old fashion. But it has it own advantages if you try to list them down.
Another type of administration emerged is new public administration. In this administration, governments contract out or privatize some of services to private sectors including civil societies. Last but not least, another term was used which is welfare administration: an administration which acts similar to that of organization focusing on result, motivation and incentive. It takes leadership style rather than management one.
To be sure that this welfare administration work well, firstly, personnel or civil servants must also be in welfare condition or self sufficiency. How personnel come to work without sufficient salary? When we talk about self sufficiency, personnel are able address beyond their basic needs. Not just foods or shelter they need. Secondly and still universal is capacity of personnel. Personnel produce results unless they possess a certain level of capacity. Salary and capacity shall be reflected, the more capacity personnel have, the more benefits should be provided by governments.
Governments might not be able to afford this welfare administration. If governments save more money in years ahead, they might introduce this administration in the country.
