School thesis
Marxian macro treats capitalism as a system of accumulation and conflict. It asks how profit, class power, competition, finance, and crisis reproduce each other over time.
Marxian approaches start from class conflict, accumulation, and profit rather than representative households and firms maximizing inside a neutral market environment.
Crises are read as recurring outcomes of capitalist production and distribution rather than unfortunate shocks around a neutral baseline.
Use when
Accumulation, profitability, class conflict, concentration, crisis, and reproduction of the system over time. The macro object is capitalism as a historically specific system rather than markets in general.
Evidence burden
Profit-share, labor-share, and mark-up evidence can show distributional conflict and market power entering inflation and investment dynamics.
Rival check
A crisis clearly driven by a non-distributional external shock with little role for profitability, finance, or class claims.
Mechanism chain
Claim
Capitalism's dynamics are driven by class conflict, profit pressure, and recurrent crises.
Mechanism
Accumulation, profitability, debt, and conflict between labor and capital generate instability over time.
Policy read
Be skeptical of policies that stabilize the system temporarily without changing the underlying distributional and institutional structure.
Mechanism
The claim needs each step in the data; a missing link weakens the whole interpretation.
Accumulation
Investment depends on expected profitability, competition, and the capacity to realize sales.
Conflict
Wages, profits, markups, and class power shape demand, inflation, and investment.
Crisis
Overaccumulation, falling profitability, debt, and realization problems can turn expansion into crisis.
Reads the economy through
class conflict / profitability / accumulation / crisis
Lineage
Historical moves show which problem the tradition was built to solve and which claim it keeps defending.
Marx
The analysis begins with production, exploitation, surplus value, accumulation, and the reproduction of the system.
Kalecki and Sweezy
Later work links investment, monopoly power, profits, and demand management.
Modern use
The strongest current use is in profit-share, labor-share, mark-up, debt, and payout analysis.
