In this paper we address the robustness of overshooting hypothesis in agricultural prices. We find that agricultural prices may undershoot their long-run level if the economy experiences an anticipated monetary shock rather than an unanticipated monetary shock. We also find that agricultural prices definitely display undershooting if the price of manufactures adjusts instantaneously rather than sluggishly. Copyright 1996, Oxford University Press.
The comparative karyological analysis of Adonis vernalis and Adonis volgensis (Ranunculaceae) from 11 populations from Russia (Altai Territory, Novosibirsk Region, Republic of Khakassia) and Bulgaria was carried out. The somatic chromosome number was 2n = 16 in all studied plants. Chromosome sets of A. vernalis from the Altai Territory (near Sibirskiye Ogni village) and the Republic of Khakassia (Tashtipskiy District), A. volgensis from the Altai Territory (near Chernopyatovo village) and Bulgaria (Kavarna Municipality) consist of eight metacentric and eight submetacentric chromosomes. Two pairs of submetacentric chromosomes had small satellites in short arms. The karyotype formula of these plants was 2n = 2x = 16 = 8m + 4sm + 4smsat. The specimen with the chromosome rearrangement (nonreciprocal translocation) was found in the Altai Territory population. The chromosome mutation has changed the chromosome morphology of submetacentric pair to metacentric pair of different size. The karyotype formula of this specimen was 2n = 2x = 16 = 2n = 10m + 6sm. A similar mutation was previously found out in A. apennina (A. sibirica) from the Tomsk Region. The nuclear DNA content (2C-value) was determined in eight Adonis populations by flow cytometry. The average absolute nuclear DNA content in A. vernalis attained on from 18.88 ± 1.01 to 19.47 ± 1.17 pg, and in A. volgensis attained on from 16.10 ± 0.41 to 16.47 ± 0.47 pg. Differences in 2C-value between A. volgensis and A. vernalis correlated with differences in total chromosome lengths of the set.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
