Micro/Macro Economics Ch 1
productivity
(also called technology) the ability to combine economic resources; an increase in productivity causes economic growth even if economic resources have not changed, which would be represented by a shift out of the PPC.

allocative efficiency
A state of the economy in which production is in accordance with consumer preferences; in particular, every good or service is produced up to the point where the last unit provides a marginal benefit to society equal to the marginal cost of producing it
who's behavioral assumption about humans was that people usually act in a rational, self-interested way.
Adam Smith's

Economics
The study of how people seek to satisfy their needs and wants by making choices, given their scarce resources

Yes, it was a voluntary exchange that benefited both parties.
revenue
a firm's revenue is the total amount received for selling a good or service. (multiply price per unit by number of units sold)
production possibilities curve (PPC)

Points on the interior of the PPC are
inefficient

negative one-half.
here is much more disagreement among economists over ______ economic analysis than over ________ economic analysis.
normative, positive
The principle of _________ is that economic cost of using a factor of production is the alternative use of that factor that is given up.
opportunity cost
The slope of a production possibilities frontier measures the ________ of producing one more unit of a good.
opportunity cost
The machines that workers have to work with are considered
physical capital.
In a modern mixed economy, who decides what goods and services will be produced?
producers, consumers, and government
When goods and services are produced at the lowest possible cost, _________ occurs.
productive efficiency
Allocative efficiency is achieved when firms produce goods and services
that consumers value most.
Efficiency
the full employment of resources in production; efficient combinations of output will always be on the PPC.
The production possibilities frontier shows
the maximum attainable combinations of two products that may be produced in a particular time period with available resources
innovation
the practical application of an invention
Technology
the processes a firm uses to turn inputs into outputs of goods and services
A firm's technology may depend on which of the following factors
the skill of its managers the training of its workers the speed and efficiency of its equipment
A firm's technology may depend on which of the following factors?
the skill of its managers the training of its workers the speed and efficiency of its equipment
inefficient use (under-utilization) of resources
the underemployment of any of the four economic resources (land, labor, capital, and entrepreneurial ability); inefficient combinations of production are represented using a PPC as points on the interior of the PPC.
opportunity cost
the value of the next best alternative to any decision you make; for example, if Abby can spend her time either watching videos or studying, the opportunity cost of an hour watching videos is the hour of studying she gives up to do that.
Who receives the most of what is produced in a market economy?
those who are most willing and able to buy them
points beyond the PPC are
unattainable
Scarcity refers to the situation in which
unlimited wants exceed limited resources
Allocative efficiency best explains ________, and productive efficiency best explains ________.
what will be produced; how something will be produced
increasing opportunity costs
when the opportunity cost of a good increases as output of the good increases, which is represented in a graph as a PPC that is bowed out from the origin
constant opportunity costs
when the opportunity cost of a good remains constant as output of the good increases, which is represented as a PPC curve that is a straight line; for example, if Colin always gives up producing 2 fidget spinners every time he produces a Pokemon card, he has constant opportunity costs.
