Solution to Homework #3
1. 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.
2. 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.
3. What is the role of the state according to Adam Smith? What makes for
good taxes?
Adam Smith believed in a minimal role for the state, a laissez-faire
approach, but he recognized that government would still be necessary. In
particular, government is needed to (1) protect society form attack by
foreigners, (2) administer justice within the country, and (3) to erect and
maintain public works and institutions the private sector cannot undertake
profitably (e.g. education, bridges, roads, canals, harbor, post office, coins,
churches, etc.)
Good taxes are taxes that (1) are proportional to the revenue enjoyed under
protection of the state (he was arguing against the current regressive
structure), (2) are predictable and uniform (time, amount, and means of
payment), (3) are levied at the time most convenient to the taxpayer, and (4)
are collected at minimum cost to the government.
