第一篇：國際學術會議發言稿
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 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 motivation of this work like this. institutional economics posits that agents making decisions on different types of transactions do so in a costly way example , farmers deciding sell a 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 cially 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 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: ? 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 cc()cη 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
q?n?market. 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 *
j?b(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(ji?j|xik)?1 exp(xij?)? k?1
based on the choice model, another important concept is famers’ channel choice , we set five types rank by the market barriers. accordingly, we set a group discrete number to express them. y: dependent variable y=5,means farmer choose
brokers. y=1, farmers sell products to consumers directly.
4. data and estimation procedures
here, we illustrate the data distribution with this map. according to the agricultural regionalization from department of agriculture, the apple specialization areas in china contain two parts: bo sea area and loess plateau. bo sea area in red color, contains hebei, shandong and liaoning 3 provinces. and loess plateau in green color, contains shanxi, henan, shaanxi and gansu 4 provinces. firstly, we use pps method to get the first stage sampling unit 14 counties in 7 provinces. then use random sample method to get village and household. they are our sample distribution.
