Introductory Lecture
Syllabus
• On line at
http://faculty.ses.wsu.edu/rosenman/econs529/
• You are expected to read through it carefully and be
aware of assignments and due dates.
– I will not necessarily remind you of due dates
– I will not accept late assignments without prior
permission
• This is where I will communicate with you, so look for
changes or announcements, which will show up at
the top of the page.
Go to syllabus and discuss
While the course focuses on research papers,
the lessons learned apply to all analysis and
jobs. The main difference may be that in
research positions you often need to come up
with your ideas, while staff jobs often tell you
what to research, but you will still need to
understand how to do good analysis
• Something to remember: Science is built up
from facts, as a house is with stones. But a
collection of facts is no more a science than a
heap of stones is a house." Henri Poincare
Lessons from the readings for today:
• Romer’s Rules for successfully finishing your graduate
program in 5 years applies to research and analysis in your
careers.
– Write, write, write. If you wait to write until you know
what you are doing, you’ll never get started. But be
aware of what Paul Weis of Yale said, “I’m not as bright as
my students. I find I have to think before I write.” Think
before you write.
– If you don’t get started, start to be concerned, and
eventually panic.
– Good research have three characteristics
• A view point: While we try to be objective, you also
have to have a purpose.
• A lever: The research uses tools to make its point.
• A result: The research adds to our understanding.
Ma talks about modern economics. His critique of modern topics is “tongue in
cheek” because all the questions he mentions are about resource allocation.
His conclusions fall into a few broad categories
– Economics is about everything.
– Modeling is how economists communicate. We are a discipline
because we share the same methodology.
•
Models always have assumptions. Assumptions drive the results.
•
We abstract, simplify and analyze. We use mathematics,
statistics, intuition and experiments.
•
Most analysis includes some data, but also is based on
abstraction that simplifies the problem (eg, choosing jobs based
on wages)
•
A common, but not absolute paradigm is optimizing behavior.
Need not be selfish. Models can include altruism.
– Read and learn from papers, not texts. Learn how to motivate and
learn techniques by reading state of the art papers. Digest new
working papers for inspiration. Work through the proofs, don’t just
read them.
Ma (continued)
–
To convince yourself that you understand the paper, explain it to
someone else.
–
To understand an issue or topic, read several papers on the it.
–
Economics can be very mathematical and you need a mathematical
maturity that few undergraduates have managed to acquire.
•
Understand definitions, assumptions, implications
•
Understand the logical steps to derive results. Y
•
Understand the difference between proofs and conjectures, and
mostly between proofs and implications.
•
Be able to go from intuition to a proof by building a model based on
reasonable assumptions. “Life is not just about interior solutions.”
(what do I and Ma mean by this?)
–
You bring your intelligence and work discipline
–
Research what interests you
–
Have self-confidence
–
Research discovery is a Poisson process. The probability that you will
discover something in the next instant is practically zero. You need to
accumulate time, hours, days, weeks even, for a positive discovery, an
example, a proof.

Read his (easy) paper for more specifics.
McCloskey
McCloskey (continued)
• Need to work on persuasion, not demonstration.
• The way things are communicated does matter.
• Rhetoric is the theory of persuasion. It is an arrangement of argument.
– Economics is built on logic and fact
– A model is a metaphor. It tells a story in a general way.
– There is a difference between economic significance and statistical
significance. Statistical significance does not say much about economic
significance. Statistical significance can only affirm a likelihood of
excessive skepticism in the face of type I errors.
• Style is the way you express yourself
– Take ownership of your work
– “Implied “ authorship (not writing in 1st person) is not especially
attractive.
– Style is what makes your work persuasive.
– His suggestion for improving persuasiveness.
