STRUCTURAL CHANGES IN RICE SUPPLY RELATIONS 35 2. Trends in the prices of rice, nonrice crops, and fertilizer (deflated by the wholesale price index) in the Philippines, 1950-74. 3. Trends in irrigated area and fertilizer consumption in the Philippines, 1950-74.
36 ECONOMIC CONSEQUENCES OF NEW RICE TECHNOLOGY rately. During the first period area expansion was the major factor that accounted for rice output growth; during the second period, the increase in yield per hectare became a major factor. Most data used in this study were collected by the Bureau of Agricultural Economics (BAEcon) of the Department of Agriculture. Rice crop area ( A ) was in terms of area harvested for both the wet and the dry season. Rice yield per hectare ( Y ) was obtained by dividing total rice output (as paddy rice) by rice crop in a crop year. Three series for the price of rice ( P ) were used: • The average unit value obtained by dividing total output value by output quantity for a crop year, • The average monthly price received by farmers for palay ordinario, • The average monthly price received by farmers for palay fancy. The latter two series were available only after 1954. Therefore, we extended them back to 1950 by multiplying the first series with the 5-year (1957–61) average ratios of the second and the third series with the first. Two specifications for the price variable used for the area response function were: • The average unit value of a previous crop year, • The average prices received by farmers for 6 months before the planting period for the wet season (February–July) of both palay ordinario and palay fancy. The three series were deflated by the wholesale price index, the price index of maize as a major alternative crop, and the price index of nonrice crops. Each of the variables of different specifications was, tried for the estimation of the area function. The price series used for the estimation of the yield response function were those of the average prices of palay ordinario and palay fancy during the wetseason planting period (May–September). The prices were deflated by the price index of fertilizers. The average prices during the preplanting period (February–July) were also tried with similar results. For the price of alternative crops ( Pa ) we used the price of maize, and the price index of nonrice crops (1965 = 100). The latter was constructed according to the Laspeyres formula covering maize, coconut, sugar, tobacco, and abaca. The price of alternative crops was included in the area response function either as a deflator of the price of rice. The price of fertilizer ( Pf ) was represented by the price of ammonium sulfate, which was included in the yield response function as a deflator of the price of rice. Monthly wholesale prices of ammonium sulfate in Manila (collected by the Bureau of Commerce) were averaged for the same periods used for averaging rice prices for the yield response function. The irrigation variable ( I ) for the area response function was the ratio of irrigated area to total cultivated area. For the yield function, it was the ratio of irrigated rice area to total rice crop area.
