The objective of the paper is to quantify the effect of the R&D investments on agricultural productivity in the Czech Republic using the co-integration analysis. The effect of the R&D investments is measured by a knowledge stock constructed using a gamma distribution with lags ranging from 7 to 15 years. The relationship between the total factor productivity in agriculture, the domestic knowledge stock and the foreign R&D spillovers approximated by the imports of agricultural technologies is examined using an error correction model. Whereas the estimates confirm that domestic research plays a positive role in agricultural productivity,...

The study analyzes the dynamic differences between the prices of black hogs and white hogs in Taiwan and determines whether these two products should be viewed as homogeneous commodities by analyzing their price volatility. Previous studies have shown that the differences in auction prices stem from the traits of the individual hogs rather than certain breeds demanding a premium because of their superior meat quality. Methodologically, this study utilizes the multivariate GARCH and the constant conditional correlation models to analyze the average daily prices of the two breeds generated by random auction sequences. Data were collected from 1485 observations,...

The paper deals with the LTPD (Lot Tolerance Percent Defective) single sampling plans when the remainder of rejected lots is inspected. There are considered two types of the LTPD plans - for inspection by variables and for inspection by variables and attributes (all items from the sample are inspected by variables; the remainder of rejected lots is inspected by attributes). These plans were created by the author of this paper and published in the Statistical Papers. These new plans were compared with the corresponding Dodge-Romig LTPD plans for the inspection by attributes from the economic point of view. From the results of the numerical investigations,...

Being the most populous countries of South Asia, Pakistan, India and Bangladesh represent about 37% of the world total undernourished population. In these three countries, the growing place of animal products can be observed in the diets, but the levels consumed for animal products remained very low as compared to the world mean. The consumption behaviour of animal products for three countries is presented in the study. Expenditure elasticities, own and cross compensated as well as non-compensated price elasticities of main animal products of these countries are calculated by using a LA/AIDS model applied to yearly data. Milk is income as well as price...
