Explain:  What do economists today say about this view of Karl Marx? List sources and the various perspectives.   "However, this equality is only formal. Once production begins, the capitalist extracts surplus value from the worker’s labor, leading to real inequality. Thus, the “equality” of free trade conceals exploitation."

Here’s how economists today tend to respond to Marx’s claim that “formal equality in exchange conceals exploitation via surplus value,” with representative sources for each camp.

=== - Position. In competitive markets with complete contracts and no frictions, each factor is paid its marginal product; voluntary exchange at market wages is therefore not exploitative in the Marxian sense. Marx’s labor-theory-of-value is seen as unnecessary for price/wage determination, and “surplus value” has no independent explanatory role.

* Sources. Paul Samuelson’s classic formal engagement with Marxian exploitation and the transformation problem; N. Gregory Mankiw’s defense of marginal-product pay and “just deserts” (with many dissenters).

=== - Position. Even without adopting Marx’s value theory, many modern economists argue real-world frictions and power can drive a wedge between pay and productivity—so “equal exchange” at the contract level can still mask extraction. Mechanisms include monopsony in labor markets, rising markups/market power, efficiency-wage discipline, and incomplete contracts.

* Evidence. - Monopsony: Higher labor-market concentration → lower posted wages. Reviews now treat monopsony as pervasive.

=== - Position. Keep Marx’s core intuition—that workers create a surplus appropriated by owners—but rebuild the theory using general equilibrium/game-theoretic concepts (property relations, feasible alternative allocations). This separates “exploitation” from the labor-theory-of-value and makes it comparable across systems.

* Examples. John Roemer’s A General Theory of Exploitation and Class; more recent formal work (e.g., Veneziani/Yoshihara; surveys and teaching notes) that retain the rate of exploitation as an empirical/analytical object.

=== - Position. Contracts are enforced within asymmetric power relations (monitoring, sanctions, exit threats). Even when trades are “voluntary,” the workplace is a site of control; exploitation is about power as much as prices. This overlaps with efficiency-wage models where unemployment disciplines workers.

=== - Position. Long-run data show wealth/income concentrating at the top; whether or not one uses Marxian language, the outcomes look like a growing surplus captured by capital/market power. American Economic Association<ref>{{cite web|title=American Economic Association|url=https://www.aeaweb.org/articles?id=10.1257%2Fjep.34.4.3|publisher=American Economic Association|access-date=2025-11-12}}</ref> ===

=== - Position. Many economists still reject Marx’s surplus-value mechanism and the labor-theory-of-value on theoretical grounds (transformation, aggregation, capital controversies), arguing competitive pricing/marginal productivity explain incomes better; others counter that those benchmarks aren’t descriptively valid in today’s concentrated, friction-ridden markets.

==== - If you assume frictionless competition: most economists say Marx’s mechanism is wrong—formal equality generally implies no exploitation.

* If you look at modern evidence on power and institutions: many economists (including non-Marxists) see systematic gaps between pay and productivity (monopsony, markups, superstar firms, falling labor share)—broadly consistent with Marx’s diagnosis that “formal equality” can mask extraction, even if they use different models and language.

If you’d like, I can tailor a short reading path (5–6 pieces) depending on whether you want the analytical-Marxist route, the monopsony/markups evidence, or the mainstream critiques.
