The CAT system is more than a testing tool and can be used to aid in instructional improvement by pinpointing difficulties in technical material areas, levels of learning abilities, general lack of understanding and patterns of mathematical, graphic and written problems. It would appear that the techniques used to develop the normative tests in this report could also be used to develop individual standarized examinations tailored to the learning objectives in other courses.","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125741125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implication of markup procedures by marketing firms on consumer prices is shown. Differential impacts on producers depend on the type of food product and scale of operation in New England.

For example, McConnell ( 1977) and Allen and Stevens ( 1979) found that the willingness to pay and consumer surplus of users of outdoor recreation facilities were related to disruptions in solitude. These studies did not, however, identify a demand schedule for solitude. In the absence of this information, the benefits of nonmarginal changes in solitude cannot be determined. In this note we apply the theory of hedonic prices to specify a demand function for solitude. Cross-sectional data of campers in Western Massachusetts were used to estimate a set of implicit marginal prices and to derive the demand function . The benefits associated with nonmarginal increases in solitude were then obtained by integrating over the estimated demand function . Our results are tentativeindeed, the primary purpose of this note is to stimulate discussion and interest in the use of the hedonic technique .","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128584988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A polynominal distributed lag model is fitted to quarterly data with deflated prices for the period 1966 to 1978. The variations in the number of milk cows is explained by about 98 percent. Farmers react positively to milk prices after l-2 years, while wages and feed prices have a negative impact on cow numbers. Milk production per cow shows positive adjustments to milk prices after 6 to 15 months. Technology and feed prices influence also milk production (R l =.87). While the short-run price elasticity of milk production is only .2, the long-run aggregate elasticity grows to 2.8 percent. Intermediate-run projections of milk supply were also performed with the model.","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"796 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134098036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This estimator has the advantages of consistency and asymptotic efficiency (for certain disturbance specifications). The one-sided residuals satisfy theoretical requirements for cost curves and all ow estimates of operational efficiency. Results indicate little size savings above 50,000 LMU, (12 percent of markets in 1976). Estimated operational inefficiencies ranged from 0 to 45 percent. Total technical efficiency (size diseconomies plus operational inefficiencies) are high for some markets and some size groups. Little consolidation is predicted for the industry because the estimated cost of technical inefficiency is small compared to distance related costs (e.g., transport and shrink).","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131693926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Problems with pooling of data, serial correlation and multicollinearity were dealt with. Estimated price elasticity of demand was found to be - .62. When this figure was compared to results of other studies (with the consideration that different estimating techniques and time periods were used) it was judged that elasticity of demand for fresh choice beef in the U.S. probably had declined between 1950 and 1978.","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129805869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a recent article in this Journal (Willis, e1 a/.) , a catalog of\"remedies\" for multicollinearity was presented to assist in reducing its level and associated adverse consequences . One of these remediesprincipal componentswas suggested as a method oftransforming a set of collinear explanatory variables into new variables that are orthogonal to each other with the first few of these transformed va riables accounting for the majority of the variability in the origina l data set. In principal components regression , a transformed variable is determined to be important a nd included or unimportant and excluded in the regression model depending upon the size of the characteristic root (eigenvalue) associated with its corresponding characteristic vector (eigenvector) (Massy), the statistical significance of its regression coefficient (Mittelhammer and Baritelle) , or some combination of eigenvalue size and correlation with the dependent variable (Johnson, et a/.) . Unfortunately, this technique is widely abused and misunderstood by the applied researcher. Confusion exists with respect to (I) its relationship to other orthogonalization techniques; (2) the meaning of the orthogonalized components and the necessity of transforming the principal component estimators back to the original parameter space; (3) the implications of deleting components and the correspondence of this technique to a particular type of restricted least squares estimator; (4) the proper way to delete components and evaluate these implied restrictions; and (5) actual implementation of this estimation procedure via available computer routines . The purpose of this note, therefore, is to place the technique of principal components in perspective and to suggest a methodology for implementing this technique correctly.","PeriodicalId":421915,"journal":{"name":"Journal of the Northeastern Agricultural Economics Council","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116101771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
