I. Para os economistas clássicos, a economia tenderia automaticamente para o pleno emprego, mesmo que houvesse intervenção governamental no mercado de trabalho por meio da fixação de um salário mínimo.
II. Keynes argumentava que, em uma economia em forte depressão, as taxas de juros estariam tão baixas que um aumento da oferta de moeda não tenderia a reduzi-las e estimular os investimentos privados.
III. Os custos de menu e dissídios coletivos, em que os salários são fixados para intervalos grandes de tempo, são duas das explicações dos economistas neokeynesianos para justificar a rigidez de preços e salários no curto prazo.
IV. Os economistas novos clássicos afirmam que as inovações tecnológicas e a substituição intertemporal da oferta de trabalho são fatores que explicam a oscilação do produto real da economia ao longo do tempo.
Está correto APENAS o que se afirma em
I. A concorrência monopolista é caracterizada pela existência de um grande número de vendedores vendendo produtos heterogêneos.
II. Na teoria neoclássica do monopólio, a receita marginal de cada unidade vendida é igual ao preço pelo qual é colocada no mercado.
III. O modelo da curva de demanda quebrada baseiase na hipótese de que, no mercado oligopolista, os preços das empresas concorrentes são rígidos para cima e flexíveis para baixo.
IV. Na teoria neoclássica do monopólio, a imposição de um tributo específico sobre as vendas do monopolista não altera o preço e a quantidade de equilíbrio transacionada no mercado.
Estão corretas APENAS as afirmações:
Q = 30.000 — 5p
onde:
Q = quantidade do bem X demandada no mercado
p = preço do bem X
Há 50 consumidores que participam do mercado do bem X. Se todos os consumidores tiverem as mesmas preferências, a curva de demanda individual de cada um, na qual "q" expressa a quantidade demandada por cada consumidor aos diferentes níveis de preço, será representada pela equação:
OFGEM'S DECISION AGAINST NATIONAL GRID'S
METERING CASE IS FURTHER ENDORSED BY THE
COURT OF APPEAL
Ofgem welcomes today's Court of Appeal ruling that
National Grid breached the law and acted anti-competitively in
the domestic gas metering market, endorsing Ofgem's April
2008 findings.
Today's ruling fully endorses the substance of Ofgem's
case, that the multi-million pound contracts struck by National
Grid with suppliers in 2002 when the metering market was
opened to competition harmed new entrants' ability to compete
and acted against consumers' interests.
The effect of the Court of Appeal's ruling is that suppliers
will be free to renegotiate the terms of contracts with National
Grid Gas, and it opens the door to claims for damages against
National Grid by competing meter operators, as the competition
law regime allows.
Welcoming today's ruling, Ofgem's Chairman Lord Mogg
said "We welcome the Court of Appeal's endorsement of
Ofgem's decision. This confirms that National Grid breached the
law and acted anti-competitively. It is a victory for consumers
and strikes a firm blow in favour of new and competing entrants
in Britain's energy market. Today's ruling shows that energy
companies who hold and abuse positions of market dominance
will face the full force of regulatory action and the law."
Today's ruling follows an earlier decision in April 2009 in
favour of Ofgem by the Competition Appeal Tribunal.

with enormous energy requirements. The growing consumer
base coupled with rapid industrial development has infused the
overall energy demand and encouraged natural gas
consumption in the country. The volatile international crude oil
prices as well as the cheaper and environment-friendly nature of
natural gas have further boosted the use of natural gas
throughout the country. This has resulted in enormous demand
for gas flow measurement and supervision devices in the
country which is all set to uplift the sales and deployment of gas
meters.
According to our latest research report "Brazil Gas Meter
Market Forecast to 2013", Brazil gas meter industry is being
increasingly benefitted by surging piped natural gas
consumption in the residential, commercial, industrial and
automobile sectors. The natural gas distribution network
reached around 18,400 Km in 2009. In order to strictly supervise
the gas flow measurement and to accurately measure its
quantity, the utilities are rapidly deploying gas meter devices in
their transportation network. These utilities are not only installing
conventional gas meters, but also rapidly opting advanced
metering devices such as AMR and AMI to ensure accurate and
immediate information on gas consumption. This adoption has
enabled utilities to automate their gas distribution networks and
upgrade safety standards in their routine operations.
