Solution to Homework 2
1. Why is the Tableau Economique important in the history of economic thought?
The Tableau (a) is the first analysis of the circular flow of goods and services through an economy, (b) represents the origins of macroeconomics, (c) provides the means to answer questions about the distribution of income, (d) foreshadows national income accounting, and (e) illustrates the notion of an equilibrium or stationary state.
2. Why was Turgot dismissed from his duties as finance minister in 1776?
Turgot managed to make just about everyone angry, except perhaps the powerless peasants:
Nobility: disliked plans to place all taxation on agriculture. Turgot tried to placate them with a tax incidence argument (i.e. that they pay it all anyway since that's the only source of surplus), but it didn't do much to ease their dissatisfaction.
Clergy: distrusted him because he didn't go to church regularly and he urged religious liberty. Also, they didn't like that he viewed them as unproductive.
Financiers: disliked that he took out loans from foreigners at lower interest rates - that cost them money.
Royal Family: weren't happy with his opposition to extravagance.
Tax farmers: didn't like that he wanted to replace them with government tax collectors.
Rich Capitalists: Turgot wanted to break up their monopolies, that didn't make them very happy.
The result: Ousted in 1776 and all of his reforms were canceled immediately.
3. What is the significance of the specie flow mechanism? Briefly, what is the essential difference between the views of Richard Cantillon and David Hume on how the specie flow mechanism operates?
The specie flow mechanism was significant because it undermined that idea that a country could run a positive balance of payments permanently - the source of wealth according to the mercantilists. Instead, the idea was based upon the natural law notion of an equilibrium that would prevail over the efforts of governments to manipulate the system to their advantage.
The essential difference between Cantillon and Hume centers on two factors, the extent to which they relied upon natural law and a notion of equilibrium, and in their analysis of exports. Cantillon said, in essence, that an inflow of gold would raise domestic prices, and that would cause imports to rise. The rise in imports would then reverse the inflow of gold and cause the nation to become more impoverished. However, in this story he does not rely upon the idea of a long-run equilibrium, and exports are not emphasized.
Hume adds both. In his model, an inflow of gold can only be temporary. As gold (specie more generally) flows in, prices rise and this causes imports to rise, as Cantillon said, but he added that exports would also fall contributing to the decline in the inflow of gold. In the long-run, there is an equilibrium (all nations at zero balance), and natural law would force economies to this equilibrium point over time.
4. According to Adam Smith, what are the four stages of economic and social development? What are the characteristics of each stage?
The four states are:
Hunting: this is the lowest, rudest stage. The economies are too small to allow privilege, power, and class, and have (essentially) equal division of goods.
Pasturage: This is the next highest stage, and it supports larger social groupings (because it is more productive). Production is centered upon domesticated animals and herding, and for that reason it is generally a nomadic culture. This represents the first accumulation of wealth (e.g. cattle), and this leads to power and class distinctions, and the need for a government to protect property and other rights.
Agriculture: An example is medieval, feudal Europe. In this stage, people are predominantly settled in one area, and agriculture is the most important activity. Thus, classes are distinguished by ownership of the land. Adam Smith thought two features were important, (i) people were limited in how they could use their wealth (there was very little manufacturing and trade), and (ii) there was very little freedom or rights for the majority of the people.
Commerce: This is the highest stage. There is an increase in freedom and rights, and this was very important to Smith. In this system, people are allowed to pursue their self-interest, and thus they had more freedom, and with the behavior properly moderated by moral sentiments and competition, the pursuit of self-interest also promoted the greater good through the harmony of interests doctrine. The development of European cities was a major force in the development of capitalism as this spurred trade and freed people from the stifling nature of feudal technology. Classes were distinguished by ownership, and he defined three classes, landlords (who own land), capitalists (who own the means of production), and laborers (who own nothing but the ability to provide labor). Capitalists were the most important of the three classes.
