David Ricardo’s Theories of Economics - 1375 Words

David Ricardo's Theories of Economics (Essay Sample) Content: Name: Professor: Course: Date: David Ricardoà ¢Ã¢â€š ¬Ã¢â€ž ¢s Theories David Ricardo was a British Political Economists and one of the most prominent figures who contributed to the development of economic theories. Born on April 18, 1772, Ricardo started his career at an early age. At 14 years, Ricardo was involved in his fatherà ¢Ã¢â€š ¬Ã¢â€ž ¢s business who was a successful stock broker. In 1793, Ricardo converted from Judaism to Christianity after marrying his longtime girlfriend, Anne Wilkinson. As a result, his family disowned him, and he stopped helping his father in the business. He then started his career as a stock broker since then. David Ricardo gained interest in economics after reading Adam Smithà ¢Ã¢â€š ¬Ã¢â€ž ¢s "The Wealth of Nations. Ricardo focused on economic policies and how they affect the economy. Among his theories is the labor theory of value which stated that the price of a good or service was affected by the amount of labor used in producing it. The theory of comparative advantage stated that when two countries are involved international trade, both countries benefit since a zero sum gain does not exist. Other approaches include wages, profits and rent. He distinguished his approach to economics by focusing on the theoretical and quantitative approach rather than a contextual approach. Labor Value of Money David Ricardo presented the Labor of money to prove that labor has a natural and market price. The natural price of labor refers to a rate that allows laborers to live. When an increase in the price of food occurs, the natural price of food also increases. Likewise, a decrease in the price of food results in a reduction in the natural price of labor. The natural price of labor has a tendency to rise with the progress of the society. However, the growth may be slightly altered by changes such as agricultural automation and the discovery of new markets. Their natural fall may also occasion food and other necessities, hence, a corresponding decrease in the natural price of labor. The market price of labor is the price paid for labor from the natural operation of the proportion of supply to demand. When labor is in plenty, the price paid for it is low while the price is high when labor is scarce. The condition of laborers flourishes when the market price of labor exceeds its natural price. The laborers have the power to command a lot of necessaries and, therefore, can bring up a healthy family. When a high wage rate is given and encourages the population, the labor force may increase, resulting in a decrease in the price of labor to their natural price. It may also fall below the natural price of labor if a reaction occurs. A drop in the price of labor affects the lifestyle of the laborers. The poverty experienced deprives them off the necessaries that they enjoy. It is only after an increase in demand for labor that the market price of labor will rise to the natural price, and the labors will lead a comfortable life which the natural rates of wage will afford (Pearcy 1). An improvement in society and an increase in its capital will affect the labor; the steadiness of the rise will depend on whether the natural price of labor has also increased. The increase in the natural price of labor will depend on the increase in natural prices of necessaries on which labor wages are expended. The Theory of comparative advantage The law of comparative advantage refers to the ability of a part to produce a good or service at a lower marginal and opportunity cost that the other party. The law of absolute advantage refers to the ability of one party to produce a good at a lower absolute cost. (Findlay 515). Countries engaging in international trade can create value for each other even when one of the parties can produce all goods with fewer resources as compared to the other party. David Ricardo used the example of England and Portugal to illustrate the theory of comparative advantage. Portugal employs 80 men to produce its annual wine supply. The labor value is 80 years of labor and the value of Portugal cloth production amounts to 90 years of labor (Bouare 105). In this case, years of labor represents the amounts of labor time an average worker takes in one year. England produces the same amount of cloth and wine. Ricardo assumed that England has a higher labor productivity than Portugal due to the lower labor productivity in England. England must spend 100 labor years to produce its annual supply of cloth and 120 labor years to produce its annual wine production. In Portugal, it is relatively possible to produce wine and cloth with less labor than it would cost England to produce the same quantities, i.e. Portugal will take 170 years or labor while England will take 220 Labor years. In England, it is relatively hard to produce wine and moderately difficult to produce cloth. In Portugal, both products are relatively easier to produce than in England. It is, therefore, cheaper to produce cloth in Portugal than in England. It is also cheaper for Portugal to produce excess wine and buy cloth from England. England benefits from this type of trade since it can get wine at a lower price, closer at the cost of producing cloth. In conclusion, each country can benefit from the trade by specializing in the goods they have an advantage in and trading it for the other good. Theory of Rent David Ricardo defined rent as payment for the use of the only land for the original powers of the soil. The return on the investment made by the landlord, after it is deducted from the contractual rent, what remains in called land rent. The law of rent applies to land in the urban and rural land (Sammut 4). Ricardo was mainly focusing on the economic rent and locational value and not the soil alone. Rent arises from the difference existing in the productiveness of different soils place under cultivation for the purpose of supplying to the same market. The amount of rent will be determined by the degree of productiveness of the land (Schneider 8). The productiveness depends on the fertility and location. Ricardo views the supply of land from the societal perspective. The scarcity of land gives rise to rent. If the problem of scarcity did not exist, land rent would not exist. When land units appear as homogenous, land rent arises. Therefore, land rent arises due to scarcity and quality of lands. Were the theories accurate? The arguments presented by David Ricardo have attracted criticism and support in e...

The Communal Power of Art Analyzing Four Great Paintings

Communal Power In many respects, one of the principle aspects of the value of art is its ability to accurately and creatively depict life around it, which in turn is responsible for the engendering of such art. Therefore, it is highly prudent to analyze the surrounding context in which art is both created and adjudged for its monetary and aesthetic merit. Even a brief analysis of the four articles contained within this document demonstrates that there is a considerable degree of influence in the society of art and artists that is responsible for most forms of creative expression, which are evinced in not just painting but also in theatrical and cinematic works of art as well. In fact, one can make a fairly substantial argument for the fact that the artistic community is largely responsible for both the creative impetus and the aesthetic validation that is necessary for truly great works of art to garner such acclaim. A close reading of Adam Gornichs Van Goghs Ear alludes to the fact that the true v alue in the communal nature of art is the interchange of ideas between colleagues that both affect that art as well as its value. It was exactly for this reason that Vincent Van Gogh highly anticipated the society of fellow painter Paul Gauguin, who was able to inspire a creative process that proved mutually beneficial to the art produced by both men. In fact, the following quotation alludes to the fact that just such a community of artists is an ideal not just for VanShow MoreRelatedThe Identity And Street Art5052 Words   |  21 PagesIdentity and Street Art Michaila Forte â€Å"An empty wall is an empty population† – Anonymous Abstract Street art emphasizes communal engagement, public activism, and awareness all while being an integrated part of a city.

Action Observation Network Research Journals

Question: Discuss about theAction Observation Networkfor Research Journals. Answer: Introduction This essay aims to elucidate a clear idea regarding the Action-observation Network in humans and review three research journals that deal with AON and the several factors influencing it. The action observation network has been widely studied in humans as well as animal models and it refers to the neural network of the brain associated with perception and prediction of human and non-human movements. This network remains active while perceiving actions and movements of others and also while recalling that information to predict performed actions and movements in the future. This network has implications in performing simple daily life tasks such as giving a high five to someone to or holding a door open for someone. On the contrary it participates in complex tasks such as socialization (Oberman, Pineda Ramachandran, 2007) or prediction skills required while driving a car or movements not possible for a person to execute or to those they are not familiar with (Ertelt et al., 2007). Bot h visual and motor cues are used to understand actions, however more brain activity has been found for actions that the person has frequently performed him/herself (Calvo-Merino et al., 2006). The brain regions that are associated with this bilateral neural pathway are premotor, parietal and temporo-occipetal cortex (Caspers et al., 2010) and the cerebellum (Sokolov et al., 2009). Cross et al. (2013) in their study aim to determine the influence of visual cues on action observation network for certain actions that the subjects are unable to perform on their own physically. They observed and compared behavioral performance and neural activity of the concerned brain regions while perceiving as well predicting visually trained and untrained actions. The sensorimotor regions of the brain are benefited both from observational and physical experiences. However, the present study was focused to evaluate the influence of visual training solely on perception and prediction of the actions of complex gymnastic sequences (biological action) and wind-up toy sequences (non-biological action). For the purpose of the study 24 participants were selected based on certain selection criteria such as participants had no neurological or psychological issues and not under any kind of medication during the experiments. A 4-days behavioral training and two functional neuroimaging scans were performed. Initially, 32 videos were shown, which acted as stimuli, 16 of them were of a biological action of three female gymnasts performing complex sequences, and the other three videos contained a non-biological action featuring wind-up toys with autonomous motions. First both were presented on a neutral background for perception of the movements and then by video editing occlusions were constructed for the participants to predict when the stimuli reappear. Neuroimages were produced for all the participants to reveal which parts of the brain remains active during perception and prediction before and after the training. Results reveal that inferior parietal, superior temporal and cerebellar cortices were more active during prediction compared to perception. Greater activity of the occipitotemporal cortices were found in untrained participants and further the occipitotemporal activity was more specialized for human movements compared to non-biological movement. The results reveal that selected portions of the AON were activated while predicting complex motions and movements and for unfamiliar movements more regions of the AON are recruited. The purpose of the study conducted by Cross et al. (2012) is to compare how the AON regions of the brain respond to human-like motion and that to robot-like motion. They used neuroimaging techniques to observe the activity of premotor, parietal and occipital regions while responding to the stimuli. They conducted two experiment, of which the first one had 22 right-handed participats and the second one 23 right-handed participants. They were selected based on absence of any neurological or psychological disorders or any medication. 36 free videos of professional break-dancers who were asked to dance wither freestyle or in a robot like fashion were used in the first experiment. In half the videos the dancer wore masks and in the other half they did not. In the second experiment, 16 of the previous videos, 8 in which the dancer dancing in a robotic manner without the mask and 16 videos prepared from software with actual robot like figures, were used. The results show the response of the AON regions were stronger for robot like motion compared to human like motion in experiment 1, and no impact of facial stimuli was observed. In the second experiment the same pattern of response was observed. The study results clearly prove that the AON is preferentially active in response to robot like compared to human like motions. It further signifies that the AON responds more robustly to unfamiliar action figure motion compared to familiar ones. The study by Gardner, Goulden Croos (2015), aims to better predict the relationship between movement familiarity and AON activity using dynamic models. Previous studies suggests than the AON is more active for familiar movements compared to unfamiliar movements. 21 adult volunteers were selected of which 17 were right-handed, 2 left-handed and the rest ambidextrous. A video of dancers performing choreographed movements that ranged from simple and predictable to complex and much less predictable steps was used as stimuli. A prediction task was designed were the participants had to choose from two still frame the following movement after 0.6s of occlusion. An attention control task was designed in which participants were shown dots (5mm) randomly appearing dots at an interval of 1s, and were asked to specify the color of the last do it after the end of the clip. The participants underwent a fMRI scan during the viewing of the movements. The familiarity of individuals to the videos was obtained by the participants rating them. The results reveal more activity in left middle temporal gyrus, inferior parietal lobule, and inferior frontal gyrus for videos with more familiarity. It further showed decrease in bidirectional activity between the parietal and temporal nodes. From the study results it can be concluded that AON activity is higher when moments were found to be more familiar to the participants. However the neural connectivity between the inferior parietal lobe and the middle temporal gyrus were decreases in case of more familiar movements which decreases prediction error.
