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 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: ? 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 power.pij?p*
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 .here, we set five types .they 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.

第二篇：英文学术会议主持人发言稿
thank you for the impressive speech .as far as we konw,shadow banking system played an important role in the last financial crisis mainly derived from its high leverage and asymmetric information characteristics.which produced a supervision dilemma.because lack of information, regulators were unable to measure the actual risk of the financial system.it is crucial for to take a further knowledge of approaches to gauge the risk exposure more entirely and more precisely.prof syc has given an eye opener as well as a very meaningful lesson.thank you again,prof syc.
thank you for your speech,miss wu. we are delighted to be able to share your new specific strategies and techniques. miss wu’s speech is about frontier science,which is profound and predictive,greatly widen our horizon,as least my horizon. anyway, i would like to express to her the most sincere appreciation capability of high tech enterprises by gray theory, please weclome mr jxs with the warmest applause.
wow what an innovative idea,to quantify the inonovation ability and classify into different categories. try to think about it and you’ ll find its very enlightening. thank you for the excellent presentations and ideas.
thank you very much for the extremely enlightening presentation. generally,we wanna investigate the correlation of asset liquidity and stock liquidity, thereby linking stock liquidity to corporate finance decisions.but the relationship between asset
liquidity and stock liquidity is ambiguous.in her speech, mrs hu introduce a useful model to explore the ambiguous relationship,which may shed new light on the importance of firm’s investment and financing decisions.
