An aggregate in economics is a summary measure describing a market or economy. The aggregation problem refers to the difficulty of treating an empirical or theoretical aggregate as if it reacted like a less-aggregated measure, say, about behavior of an individual agent as described in general microeconomic theory. Examples of aggregates in micro- and macroeconomics relative to less aggregated counterparts are: Franklin Fisher notes that this has not dissuaded macroeconomists from continuing to use such concepts.

  • Während in der Mikroökonomie individuelles Verhalten von Unternehmen und Haushalten untersucht und mittels mikroökonomischer Funktionen beschrieben wird, werden in der Makroökonomie funktionale Zusammenhänge zwischen den aus mikroökonomischen Variablen zu makroökonomischen Variablen aggregierten Größen unterstellt. Das Aggregationsproblem besteht in der Frage, ob und wie mikroökonomische und makroökonomische Funktionen miteinander vereinbar sind. (de)
  • An aggregate in economics is a summary measure describing a market or economy. The aggregation problem refers to the difficulty of treating an empirical or theoretical aggregate as if it reacted like a less-aggregated measure, say, about behavior of an individual agent as described in general microeconomic theory. Examples of aggregates in micro- and macroeconomics relative to less aggregated counterparts are: * Food vs. apples * Price level and real GDP vs. the price and quantity of apples * Capital stock vs. the value of computers of a certain type and the value of steam shovels * Money supply vs. paper currency * General unemployment rate vs. the unemployment rate of civil engineers Standard theory uses simple assumptions to derive general, and commonly accepted, results such as the law of demand to explain market behavior. An example is the abstraction of a composite good. It considers the price of one good changing proportionately to the composite good, that is, all other goods. If this assumption is violated and the agents are subject to aggregated utility functions, restrictions on the latter are necessary to yield the law of demand. The aggregation problem emphasizes: * How broad such restrictions are in microeconomics * Use of broad factor inputs ("labor" and "capital"), real "output", and "investment", as if there was only a single such aggregate is without a solid foundation for rigorously deriving analytical results. Franklin Fisher notes that this has not dissuaded macroeconomists from continuing to use such concepts. (en)
  • Em macroeconomia um agregado é uma medida síntese descrevendo um mercado ou economia. O problema da agregação refere-se à dificuldade de tratar a reação de um agregado empírico ou teórico a uma medida menos agregada, por exemplo, sobre o comportamento de um agente individual, como é descrito na teoria microeconómica em geral. São exemplos de agregados em micro e macroeconomia, relativamente a conceitos correspondentes menos agregados: * alimentos vs maçãs. * o nível dos preços e do PIB real vs. o preço e a quantidade de maçãs * o capital fixo da economia vs. o valor dos computadores de um determinado tipo * a oferta de dinheiro vs papel-moeda. * a taxa de desemprego geral vs. a taxa de desemprego de engenheiros civis.
