Question

While it may seem simple and unobjectionable to non-specialists, one of the many issues that illustrates the divergence of post-Keynesian economics from mainstream economics is the idea of time. Most models of neoclassical economics utilize the notion of "logical time," in which markets (whether they be capital, goods, or labor markets) return to equilibrium after a disturbance is introduced and then overcome. While few economists object to this general model, post-Keynesians try to shift focus away from the "long run"-level analysis and analyze instead events in "historical time," emphasizing the real-world effect of deviations from equilibrium.

However, post-Keynesian economics cannot be understood simply as a reaction to, or adjustment of, the ideas of Keynes. In fact, because many post-Keynesians believe that the movement known as Keynesianism actually represents a severe divergence from the ideas of Keynes, they are in the position of both resuscitating and updating his theories. One example of this phenomenon is the labor market, on which traditional Keynesians follow the classical theory (that is, pre-Keynesian) of unemployment.  While traditional and post-Keynesians both support   (known as "pump-priming") as a solution to short- and medium-term inefficiencies in the labor market, traditional Keynesians believe that, so long as wages and prices are perfectly flexible, those inefficiencies will disappear.  That is the extent of the story for the traditional Keynesian, but viewed through the lens of "historical time," such inefficiencies are problems worthy of the economist's further study.   1 
 1. The passage suggests which of the following about the deficit spending mentioned in the highlighted text?

(A) To a traditional Keynesian, it is a way to eliminate inefficiencies in the labor market.
(B) To a post-Keynesian, it solves all of the problems associated with inefficiencies in the labor market.
(C) To both traditional and post-Keynesians, it is a key aspect of the classical theory of unemployment.
(D) To a traditional Keynesian, it is a way to turn attention away from "long run"-level analysis.
(E) To a post-Keynesian, it is a superior strategy to that of "pump-priming."

(B) It applies most directly to theories of the labor market, which has long been misunderstood by economists.
(C) It represents the most serious problem with the positions held by post-Keynesians.

(C) They favor the notion of "historical time" to that of "logical time."
(D) They support more of the theories of Keynes than do post-Keynesian economists.
(E) As neoclassical economists, they study the real-life impact of inefficiencies that appear in the capital, goods, and labor markets.

 4. The passage is primarily concerned with

(B) evaluating competing explanations of equilibrium in the labor market
(C) comparing the notion of “historical time”with that of “logical time”as they apply to economics
(D) clarifying the positions of a misunderstood ...eld of economics by explaining a key di¤erence with another field
(E) suggesting that “long run”-level analysis leads to economic misunderstandings and poor policy

 5. Which of the following best summarizes the main point of the passage?

(A) The importance of time in economic theories has long been understated, and its inclusion sheds new light on possible methods to curtail unemployment.
(B) The appearance of the post-Keynesian school of economics allowed mainstream economists to abandon their reliance on traditional theories such as the classical theory of unemployment.
(C) The ideas of Keynes remain among the most crucial in contemporary economic thought, but traditional Keynesians have long misrepresented them.
(D) Traditional Keynesians and post-Keynesians share some views, but the way each group approaches the idea of time causes them to pursue di¤erent paths of study.
(E) The labor market is a controversial sub...eld of economics, one in which Keynesians have little to contribute.

 6. Which of the following best characterizes the di¤erence between the way traditional Keynesians and post-Keynesians view ine¢ ciencies in the labor market, as described in the passage?

(A) Post-Keynesians di¤er from traditional Keynesians by studying practical e¤ects of ine¢ ciencies in the labor market.
(B) Traditional Keynesians di¤er from post-Keynesians in that they consider short-term ine¢ ciencies less important than medium-term ine¢ ciencies.
(C) Post-Keynesians and traditional Keynesians both accept the accuracy of the classical theory of unemployment and diverge only in the details of its interpretation.
(D) Traditional Keynesians di¤er from post-Keynesians in that each group had a substantial e¤ect on the history of economic thought at di¤erent points in the 20th century. 
(E) Both post-Keynesians and traditional Keynesians consider both “historical time”and “logical time”in evaluating the most important topic of study within the ...eld of unemployment.

 7. According to the passage, “logical time”is

(A) an aspect of most models of neoclassical economics
(B) now considered less useful than “historical time”
(C) irreconcilable with “long run”-level analysis

Original Explanation

OA: A

The second paragraph notes that deficit spending is something both traditional and post-Keynesians agree on as a solution to certain inefficiencies.

Choice (A) doesn't represent all of that, but it does state something true, that traditional Keynesians support it as a method.

Choice (B) is too extreme, using the phrase "solves all of the problems."

(C) is inaccurate, as it sounds like decit spending is an aspect of this theory, but not necessarily a key aspect.

(D) is wrong, as traditional Keynesians favor "long run" analysis.

(E) is also incorrect, as deficit spending and "pump-priming" are two terms for the same concept.

(A) is correct.

OA:E

Most of the passage is about time in some form or other, so rather than trying to predict the parameters of an answer, proceed through the choices.

(A) is too strong, as the author doesn;t tell us that post-Keynesians represent a particularly "trenchant" critique.

(B) is an irrelevant comparison, as the passage doesn't discuss any other applications. We don't know it applies most directly to the labor market.

(C) is another irrelevant comparison ("most?") and the author doesn't take a stance on whether it is a problem.

Choice (D) conflates theory (the level at which we talk about "historical time," for instance) and actual real-life effects, such as those brought about by deficit spending. A theoretical concept isn't what wreaks havoc with something in the real world.

(E) finally, is correct. The whole reason that time is discussed is to describe where two schools of thought diverge.

OA:A

Traditional Keynesians play a large part in this passage, but their specific positions are not often defined; we may have to look for an answer that represents something different from what we know about the positions of post-Keynesians.

Choice (A) is exactly that. We know that Keynesians generally support deficit spending to solve short- and medium-term inefficiencies, and that post-Keynesians differ in that they focus on more than just those inefficiencies. Thus, it can be inferred that traditional Keynesians are not interested in other things ("That is the extent of the story for the traditional Keynesian").

(B) misrepresents the passage, in which Keynesians are said to generally support deficit spending/"pump priming."

(C) gets the distinction backwards; traditional Keynesians use "logical time."

(D) is up for debate, as "many post-Keynesians believe that the movement known as Keynesianism actually represents a severe divergence from the ideas of Keynes."

Most of (E) is correct, but it is unclear in the passage whether traditional Keynesians are neoclassical economists.

Question #4

The main focus of the passage is defining post-Keynesians, specifically as regards their theory of time.  Choice (A)  isn’t too far off, but it isn’t exactly right that the passage uses time to illustrate a different view, and it is off-topic to put that in terms of its role in neoclassical economics.

Question #6

The relevant sentence is the last one in the first paragraph:  “post-Keynesians try to shift focus away from the ’long run”’-level analysis and analyze instead events in ’historical time, emphasizing the real-world effect of deviations from equilibrium.”   Choice (A) ’s reference to  “practical effects of inefficiencies”  is synonymous with  “real-world effect of deviations,”  and the question tells us we’re focusing on the labor market.
