failure of accepted political economy to give sufficient weight to changes in aggregate demand and to the resulting possibility that under some situations an artificial demand could put to use resources … otherwise unemployed." This essentially recommended that an artificially determined demand could stimulate available capital and the market. Secondly, Scrope lamented the "evil effects of falling prices on total production as well as on the distribution of income and the need for banking reform to raise prices on the existing gold standard." Scrope advocated that a tabular standard be instituted, allowing the banking system and the economy to keep up with the market. Jevons eventually aided in inserting the tabular standard, but gave large credit to Scrope and Lowe, who independently co-discovered it. The third primary theme of Scrope’s articles to the Quarterly Review, according to Frank Whitson Fetter, is the "fallacies of Malthusian population doctrine and of the current proposals for sweeping reform of the poor laws that were based on the acceptance of the Malthusian view [that they be administered to] discourage population increase." Scrope was an opponent of Ricardo's Malthusian ideas as well. Ricardo was an accomplished economist and a Member of Parliament for Port Arlington during the years 1819-1823. Scrope rejected Ricardo's definition of "rent theory" which was, according to the Wikipedia entry under Ricardo's name (cited below), "the difference between the produce obtained by the employment of two equal quantities of capital and labor." The model for this theory of rent essentially stated that while only one grade of land is used for agriculture, rent will not exist, but when multiple grades of land are being utilized, rent will be exacted on the higher grades and will increase with the rise of the grade. "As such, Ricardo believed that the process of economic development, which increased land utilisation and eventually led to the cultivation of poorer land, benefited first and foremost the landowners because they would receive the rent payments either in money or in product." To his Principles of Political Economy, deduced from the Natural Laws of Social Welfare, and applied to the Present state of Britain he prefixed it as a "Preliminary Discourse on the coincidence of the rights, duties and interests of man in society" in an effort to define "the true scope and limits of political economy, and also of establishing a ground-work of axiomatic principles with respect to the
