Cheap MBAs: Costly for some
Apr 21st 2016, 14:31 by C.S-W.
THERE'S no such thing as a free lunch. That maxim should be ingrained in the minds of business-school students, attuned
to the notion of opportunity cost or Milton Friedman’s economic theories. Yet to believe the American non-profit University
of the People (UoPeople), run by Shai Reshef, an Israeli entrepreneur, something close to a free lunch could soon be
available to prospective MBA students. On March 15th the university opened applications for an MBA without tuition fees
that it plans to launch in September 2016.
That much is admirable, and certainly should be applauded. But don’t prepare to burn Friedman’s 1975 tome yet: there’s still
no such thing as a free lunch. One hundred successful applicants will be enrolled onto the 15-month distance-learning
course, and will be asked to pay just $200 for each of the 12 courses they will take as part of the programme. That is still a
pittance, and a minuscule fraction of the cost of an MBA at the sort of business schools ranked by The Economist. “The cost
of an MBA today is so expensive that many people who are qualified to achieve it cannot afford it,” Mr Reshef said when
announcing his plans.
Certainly, business schools can be rarefied places. So the development of a legitimate MBA at a low cost could be beneficial.
Russell Winer, professor of marketing at NYU Stern and the leader of the MBA programme at UoPeople, told The
Economist that the establishment can offer a cheaper programme than most by being online-only and lean-staffed.
It also has the backing of faculty members from other big business schools, including INSEAD, Wharton and Oxford, all of
whom have helped develop the curriculum. And yet the devil is in the detail. Some fine minds are drawing up the cut-price
curriculum, yes, but they are too busy teaching at their main employers actually to impart the knowledge they put to paper.
Mr Winer, the head of the programme, won’t be teaching his course on marketing, and doesn’t know who will be, or what
their qualifications are. “I tend not to be that involved that much in the day-to-day aspects of the running of the programme,”
he explained.
Mr Winer does not believe course material being drawn up by one person and taught by another, perhaps less-qualified
instructor, is a hindrance: what is taught is more important than the way it is administered, he reckons. And “there’s no
question about the academic legitimacy of our programme,” he says. But hobnobbing with lecturers and their associates is
a big part of most MBAs' appeal, and could well be found lacking in UoPeople’s delegated and peer-led programme.
Then there is perhaps the bigger question of whether employers will take it seriously. Well-resourced business schools fight
hard to attract the most prestigious employers. Employers, in turn, are impressed by big academic names. Many see MBA
admissions officers as an important filter: if students are impressive enough to get into a top-ranked programme, then that
cuts down the need to broaden their search when it comes to hiring. (UoPeople is not accredited by one of the three big
global business-school agencies, meaning it wouldn’t be considered for many rankings.) A cut-price education should be
applauded, but a cheap MBA that employers do not view as credible is still costly in relative terms, particularly for those who
can least afford it.

Respostas que contenham a ideia Because they are expensive and very few people can
afford them/Pay to study there
3. Whats is Mr Winer’s opinion about having the curriculum and course contents developed by one
person and taught by another?
Respostas que contenham a ideia: For him it’s not a problem, because he thinks what is
taught is more importante than how it is taught.
4. Why does the author doubt employers will take the course described seriously?

PROIBIDO o uso de calculadoras e similares;
Duração: 2 HORAS.
Nas questões discursivas EXPLICITAR os cálculos.
Questão 1 (10 pontos). O gráfico da função do segundo grau f(x) = ax2 + 2bx + c
passa pelo ponto (0, 1) e tem um máximo em (1, 4) então, os valores de a, b e c são
respectivamente
a) −1, 0 e 1
b) 1, 1 e 3
c) 3, −3 e 1
d) −3, 3 e 1
Resposta: d)
Avaliando a função em x = 0 obtemos c = 1. Derivando temos f ′ (x) = 2ax + 2b, para
que x = 1 seja ponto de máximo devemos ter f ′ (1) = 0, daı́ temos b = −a. Avaliando a
função em x = 1 obtemos a − 2a + 1 = 4, donde a = −3. Logo, os valores são −3, 3 e 1,
respectivamente.
Questão 2 (10 pontos).

Resposta: c)
Primeiramente note que o quociente das funções não está definido em x = 2. Os sinais
são
f(x) < 0 ⇔ x ∈ S1 = {x ∈ R|x < −3}
f(x) ≥ 0 ⇔ x ∈ S2 = {x ∈ R|x ≥ −3}
g(x) < 0 ⇔ x ∈ S3 = {x ∈ R|x < 2}
g(x) ≥ 0 ⇔ x ∈ S4 = {x ∈ R|x ≥ 2}
como queremos o quociente negativo ou nulo de vemos tomar S2 ∩ S3 = [−3, 2).

Questão 6 (10 pontos). Uma empresa produz diariamente x calças a uma função
custo C(x) = 400 + 30x dinheiros. Considerando que as calças serão vendidas a um valor
2
fixo e inteiro de dinheiros, qual a menor valor de venda para que a empresa tenha lucro
vendendo 40 calças por dia?
Resposta:
Chamando a receita de R(x) = ax. Igualando a receita com o custo na produção de 40
calças temos equilı́brio, receita igual a custo, em a = 40. Daı́ a calça deve custar mais
de quarenta dinheiros.
Questão 7 (10 pontos). O custo total para produzir x unidades de certo produto
é C(x) = 2x2 + 4x + 20 dinheiros. Se o produto é vendido 20 dinheiros e supondo que
toda a produção é absorvida, determine quantas unidades devem ser vendidas para que
o lucro seja máximo.
Resposta:
A função lucro será receita 20x menos a função custo, logo
L(x) = 16x − 2x2 − 20.
Derivando temos, L ′ (x) = −4x + 16, assim o ponto crı́tico é x = 4. Tomando a derivada
segunda obtemos L ′′ (x) = −4 < 0. Assim x = 4 é ponto de máximo.
Questão 8 (10 pontos).
Determine o conjunto solução do sistema
{
(x − 2)|x + 1| < 0
4x − 14 ≤ x − 5
Resposta:
A inequação (x − 2)|x + 1| < 0 tem solução x < 2 com x ̸= −1,
S1 = {x ∈ R|x < 2} ∩ {x ∈ R|x ̸= −1}
e a segunda inequação tem solução
S2 = {x ∈ R|x ≤ 3}
Logo, a solução é S1 ∩ S2 .

Encontre o conjunto solução sistema


x + y − z = 2
2x + 2y + z = 3


Resposta:
Somando a primeira e a última obtemos 2x + 2y = 3 subtraindo este da segunda temos
z = 0, inserindo z = 0 nas equações vemos que x + y = 2 e x + y = 1 que não possui
solução, logo o conjunto solução do sistema é vazio.
