Brilliance or GloomBrilliance or Gloom

The Wonderful World Adam Smith Envisioned was being embraced by some philosophers

A minister by the name of William Godwin saw the poverty around him but was convinced that the world’s future was much brighter

Brilliance or GloomBrilliance or Gloom Godwin foresaw a future where

– [t]here will be no war, no crime, no administration of justice, as it is called, an no government. Besides this there will be no disease, anguish, melancholy, or resentment

He even dared state that there would be no longer a need for a marriage contract. His ideas were controversial but due the high cost of his pamphlet very few read it and thus he was not prosecuted by the Privy Council

Privy CouncilPrivy Council

The Privy Council is one of the oldest parts of British Government, it has, over time, adapted to reflect the fact that the United Kingdom is a constitutional monarchy.

It deals with many of the legal issues the government must deal with

Both the theories of Malthus and those proposed by Ricardo led Thomas set a much gloomier outlook than that proposed by Adam Smith, William Godwin, and Condorcet

Dismal Science: EconomicsDismal Science: Economics

According to Heilbroner, as well as many other, Thomas Carlyle after reading Thomas Malthus book described economics as “the “dismal science”

However, recent work by David Levy, Journal of History of Economic Thought, 2001 argues that Carlyle did coin the phrase

Page 8: A Step Back to Reality ?

Dismal Science: EconomicsDismal Science: Economics

However, Levy argues that Carlyle used the term to refer to the fact that classical economists’ view on race, not their views on population. He called it a dismal science because economics saw all races as equally capable of entering into trades whereas Carlyle believed that the races were different and that slavery was natural for blacks.

Recall that Malthus’ hypothesis could be summarized simply by– The fact that while population grows at a

geometric rate, food production grew at an arithmetic rate

Thomas MalthusThomas Malthus

The ideas of Malthus influenced many of his time

Among them, Charles Darwin and David Ricardo

Darwin in the development of his theory of natural selection was greatly influenced by the observation made by Malthus that like plants and animals, humans can overproduce offspring if left unchecked.

MALTHUS AND RICARDOMALTHUS AND RICARDO

Malthus and Ricardo were above all great friends.

They disagreed with each other on many points which in reality where more an issue of style rather than substance.

However they did have one very important difference of opinion.

Page 12: A Step Back to Reality ?

MALTHUS AND RICARDOMALTHUS AND RICARDO

This difference was in the fact that David Ricardo supported the so called Says Law while Malthus did not

We will discuss the Says Law in greater detail later on

Short-run price changes are due to demand-supply while Long-run price changes due to labor costs

Any variation of the preceding is only temporarily and in all cases Long-run price changes are due to labor cost changes

Basic Assumption of the Law of Basic Assumption of the Law of Comperative AdvantagesComperative Advantages

Each Country has a fixed endowment of resources, and all units of each particular resource are identical (i.e. homogenous factors).

The factors of production are completely mobile between alternative uses within a country factor prices identical for alternative uses.

Page 25: A Step Back to Reality ?

Assumptions (Cont)Assumptions (Cont) The factors of production are completely immobile

externally (i.e. across countries) factor prices can be different across countries prior to trade

A labor theory of value is employed for the model. Thus the value of the product is determine solely by the value of its labor (a) no other input is being used, or (b) the other inputs are measured in terms of its labor cost, or (c) the other input/labor ratios.

Page 26: A Step Back to Reality ?

Assumptions (cont.)Assumptions (cont.) are the same in all industries.

The level of technology is fixed in each country during the period under consideration, although the technology can differ between them.

Costs of production are constant horizontal supply curve.

Page 27: A Step Back to Reality ?

There is full employment.

There is perfect competition.

No government-imposed obstacles to economic activity.

Internal and external transportation costs are zero.

We begin with a two-country and two-commodity trade

Page 29: A Step Back to Reality ?

If the Autarky Price ratio is the pre-trade price ratios.– These are based on the opportunity cost– England 1 W : 1.2 C– Portugal 1 W ; 8/9 C
