【学术会议的发言稿开场白】一
1. prologue
thank you, mr. chairman, for your gracious
introduction. i am honored to have the chance to address
you on this special occasion. the topic of my paper is
“transaction cost and farmers’ choice of agricultural
products selling”. the outline of my talk as follows.
the first part i want to introduce the background of this
research. the second part suggests a simple household
choice model .the third part covers the data used in this
research. and then, we introduce the empirical results.
finally, a simple conclusion is given.
2. introduction
well, let’s move on the first part of this
topic .the motivation of this work like this.
institutional economics posits that agents making
decisions on different types of transactions do so in a
costly way .for example , farmers deciding sell a
1
particular crop to whom base their decisions not only on
the price they expect to receive in each market choice
but also on additional costs related to transacting in
these markets.
i want to use a picture to illustrate it. for
example, given some market channels, farmers’ choices
can be regarded as equilibrium between the surplus and
the additional costs that related to
transacting .especially in developing countries, high-
value crop producers fully participate in the market and
the transaction cost has been the hard constraint to
farmers. furthermore, farmers’ market choices can be
taken as a choice dilemma of transaction cost and
production surplus. consequently, the scientific question
of this research is how transaction cost affects
planters’ choices.
3. methodology
let’s move to the theoretical model of our research.
consider a household model in one rotation. in stage 1 ,
famer η needs to allocate the input factors .this
process can qbe set into a function like this q q( p ,
w , z ) , qη means the output farmers decide qto produce
.p implies the output price w implies input price and.z:
2
is fixed input. once produce what and produce how many
are decided, next question to be considered is how much
products to be transacted in market. here we use three
cccη means how functions to describe this question. the
first equation, c p , z
much agricultural products used by famers themselves.
p implies the price the cagricultural product,z suggests
the fluctuation of cη. the second equation q q c, qη
means the amount of agricultural products transacted in
qnmarket. the third equationi q implies the amount
exchanged in nth time.
in stage 3, farmers will decide to sell the products
to whom. chanel j’s market price is
bdecided by an exogenesis price and farmers’
negotiating power.pijp*
jb(qi,zi)besides this, we use a matrix to show the
net profit of chanel jx ik ik, ik
and then farmers’ choice can be expressed in a
typical choice model
exp(xij)pr(jij|xik)1 exp(xij) k1
based on the choice model, another important concept
is famers’ channel choice .here, we set five types .they
rank by the market barriers. accordingly, we set a group
