The question asks to identify the type of inflation caused by higher money wages secured by powerful trade unions. This scenario directly relates to cost-push inflation, specifically when the cost of labor increases.
A) wage-push inflation is the correct term for inflation caused by higher money wages, as it directly reflects the increase in labor costs being pushed onto consumers through higher prices.
The question asks to identify the type of inflation that occurs when firms in monopolistic or oligopolistic industries increase their profit margins. We need to understand the different types of inflation mechanisms to correctly answer this.
B) profit-push inflation. This type of inflation occurs when firms with significant market power (e.g., monopolies or oligopolies) raise their prices to increase their profit margins, rather than in response to rising production costs. This directly matches the description in the question.
The question asks about the effects of an upward shift in the aggregate supply (AS) curve in the context of cost-push inflation. We need to analyze how this shift impacts the equilibrium price level and output (real GDP) in the aggregate demand-aggregate supply (AD-AS) model.
C) a fall in output and a rise in the price level
The question asks to identify the economists who attributed the observation that cost inflation "has been the layman's instinctive explanation of general price increases." This requires knowledge of specific economic theories and the economists associated with them, particularly in the field of inflation.
D) Bronfenbrenner and Holzman are credited with the observation that cost inflation "has been the layman's instinctive explanation of general price increases." This statement highlights the common public perception of inflation being driven by rising costs, a concept they discussed in their analysis of inflation theories.
The question asks about the economic impact of a sudden rise in global crude oil prices. This is a classic example of a supply shock. We need to understand how such a shock affects the general price level in an economy.
A) cost-push inflation — A sudden steep rise in global crude oil prices increases the cost of production for businesses across various sectors. This increase in input costs forces businesses to raise the prices of their final goods and services to maintain profit margins, leading to a general increase in the price level, which is the definition of cost-push inflation.
The question asks about the period when cost-push inflation first gained significant attention from economists. This requires knowledge of the historical development of economic thought regarding inflation.
B) 1950s — Cost-push inflation began to attract serious attention from economists during the 1950s. This period saw the development of theories that explained how rising production costs, independent of aggregate demand, could lead to inflation. Economists observed situations where prices rose due to wage increases or supply shocks, prompting a shift in focus from purely demand-side explanations of inflation.
