Construction of hypotheses: specify one or more equations of a model based on economic theories. Show underlying theory using …rst and second order conditions of optimisation or by solving a system of equations. It helps to use diagrams to show these relations Prepare most suitable data for analysis Estimate parameters and check if signs or magnitudes of estimated parameters or variables are consistent with the theory. Analyse variance by R 2 , F and χ2 and signi…cance of coe¢ cient by t tests. Econometric tests: heteroskedasticity, autocorrelation, stationarity, coitegration, mispeci…cation or measurement errors. Write an essay or article based on research experience gained following above steps. Dr. Bhattarai (HUBS)

Empirical speci…cation Empirical analysis requires some manipulation of the original derivation. It is easier to convert this nonlinear demand function to a linear one by taking logs as: ln C1 = ln α + ln I
ln P1
There are i = 1...n consumers. De…ne ln C1,i = Yi ; ln P1,i = β2 Xi ;
(4) β1 = ln α + ln I ;
Yi = β1 + β2 Xi + ei
(5)
Expected signs of intercept β1 > 0. This is the demand expected when price is zero; component of demand that does not respond to price leve. Slope β2 < 0 for a normal good when prices rise demand will fall.

Preparing data for demand analysis Let us consider demand for wheat. Data on individual commodities can be obtained from various surces such as http://www.ers.usda.gov/Data/Wheat/YBtable01.asp When data is constructed the unknown parameters β1 and β2 can be estimated. See data …le wheat.csv Table: Regression of wheat production on its price
Coe¢ cient Stadard Error Intercept 29.44 4.02 Wheat price 1.12 0.99 2 R = 0.06 , F = 1.3 , N = 23.
t-value 7.32 1.12
This is not a strong relation, need to do more research. Derivation of OLS estimators and test to follow next week. Dr. Bhattarai (HUBS)
