Equality of Opportunity
John E. Roemer
Harvard University Press, 1998

John Roemer points out that there are two views of equality of opportunity that are widely held today. The first, which he calls the nondiscrimination principle, states that in the competition for positions in society, individuals should be judged only on attributes relevant to the performance of the duties of the position in question. Attributes such as race or sex should not be taken into account. The second states that society should do what it can to level the playing field among persons who compete for positions, especially during their formative years, so that all those who have the relevant potential attributes can be considered.

Common to both positions is that at some point the principle of equal opportunity holds individuals accountable for achievements of particular objectives, whether they be education, employment, health, or income. Roemer argues that there is consequently a "before" and an "after" in the notion of equality of opportunity: before the competition starts, opportunities must be equalized, by social intervention if need be; but after it begins, individuals are on their own. The different views of equal opportunity should be judged according to where they place the starting gate which separates "before" from "after." Roemer works out in a precise way how to determine the location of the starting gate in the different views.

An Introduction to Marxist Economic Philosophy
John E. Roemer
Harvard University Press, 1988
Attacking the usefulness of such central Marxian concepts as the labor theory of value and surplus value, John Roemer reconstructs Marxian economic philosophy from the concepts of exploitation and class, showing that exploitation can be derived from a system of property relations. He then looks at the causes of the unequal distribution of wealth, including robbery and plunder, willingness to take risks, differential rates of time preference, luck, and entrepreneurship. He further examines the evolution of property systems—slave, feudal, capitalist, socialist—from the perspective of the theory of historical materialism, and ends by analyzing the properties of a social system in which ownership of productive assets in the external world is public, while ownership of internal productive assets—skills and talents—is private.

A Future for Socialism
John E. Roemer
Harvard University Press, 1994

Many people point to recent events—the collapse of the Soviet Union, the electoral defeat of the Sandinistas—as proof that capitalism has triumphed over socialism once and for all. In A Future for Socialism, a noted economist argues that socialism is not dead but merely in need of modernizing. John Roemer believes that the hallmark of socialism is egalitarianism—equality of opportunity for self-realization and welfare, for political influence, and for social status—and he reminds us that capitalist societies face increasingly difficult problems of poverty and social inequality. Reenergizing a debate that began with Oskar Lange and Friedrich Hayek in the late 1930s, he brings to important questions of political economy a new level of sophistication in line with contemporary theories of justice and equality.

Roemer sees the solution of the principal-agent problem as the key to developing a decentralized market-socialist economy. This would be capable of maintaining efficiency and technological innovation while supporting a substantively more equal distribution of income than is achieved in capitalist economies. Roemer defends his views against skeptics on the right, who believe that efficiency and innovation are incompatible with egalitarianism, and skeptics on the left, who believe that socialism is incompatible with markets.

Because of its interdisciplinary approach, A Future for Socialism will appeal to a general social science audience, including economists, political scientists, sociologists, and political philosophers. It is also accessible to the interested reader.

A General Theory of Exploitation and Class
John E. Roemer
Harvard University Press, 1982

How can exploitation and even class division occur in socialist societies? The question is not merely embarrassing for Marxists and socialists. It is also a deep puzzle for economic theorists. In this original and powerful work, John Roemer proposes a general theory of exploitation which provides a game theoretic framework for expressing any conception of exploitation—feudal, capitalist, or socialist—in a standardized and explicit way, thus permitting a clear comparison of different ethical conceptions. As well as applying the general theory to an analysis of socialist society, Roemer uses it to contrast Marxian and neoclassical conceptions of exploitation. By placing the Marxian conception of exploitation in the context of a more general theory, Roemer provides fresh insights into classical questions, and resolves several old problems in Marxian economics.

The book also contains a formal theory of class formation. Once the behavior and institutional specifications of an economy are given, classes emerge endogenously in the model. In a major theorem Roemer relates the two key characteristics of a person in a given economy: his class position and his status as exploiter or exploited. Finally, he shows that the general theory of exploitation can be viewed as the formal translation into economic language of the theory of historical materialism. In its mathematical power and precision, its skillful use of general equilibrium and game theory, the book will become an important bridge between Marxist and neoclassical economics.

Political Competition
Theory and Applications
John E. Roemer
Harvard University Press, 2001

In this book, John Roemer presents a unified and rigorous theory of political competition between parties. He models the theory under many specifications, including whether parties are policy oriented or oriented toward winning, whether they are certain or uncertain about voter preferences, and whether the policy space is uni- or multidimensional. He examines all eight possible combinations of these choice assumptions, and characterizes their equilibria.

He fleshes out a model in which each party is composed of three different factions concerned with winning, with policy, and with publicity. Parties compete with one another. When internal bargaining is combined with external competition, a natural equilibrium emerges, which Roemer calls party-unanimity Nash equilibrium.

Assuming only the distribution of voter preferences and the endowments of the population, he deduces the nature of the parties that will form. He then applies the theory to several empirical puzzles, including income distribution, patterns of electoral success, and why there is no labor party in the United States.

Racism, Xenophobia, and Distribution
Multi-Issue Politics in Advanced Democracies
John E. Roemer, Woojin Lee, and Karine Van der Straeten
Harvard University Press, 2007

From the Republican Party's "Southern Strategy" in the U.S. to the rise of Le Pen's National Front in France, conservative politicians in the last thirty years have capitalized on voters' resentment of ethnic minorities to win votes and undermine government aid to the poor. In this book, the authors construct a theoretical model to calculate the effect of voters' attitudes about race and immigration on political parties' stances on income distribution.

Drawing on empirical data from the U.S., Britain, Denmark, and France, they use their model to show how parties choose their platforms and compete for votes. They find that the Right is able to push fiscal policies that hurt working and middle class citizens by attracting voters who may be liberal on economic issues but who hold conservative views on race or immigration. The authors estimate that if all voters held non-racist views, liberal and conservative parties alike would have proposed levels of redistribution 10 to 20 percent higher than they did. Combining historical analysis and empirical rigor with major theoretical advances, the book yields fascinating insights into how politicians exploit social issues to advance their economic agenda.

Sustainability for a Warming Planet
Humberto Llavador, John E. Roemer, and Joaquim Silvestre
Harvard University Press, 2015

Human-generated greenhouse gas emissions imperil a global resource: a biosphere capable of supporting life as we know it. What is the fair way to share this scarce resource across present and future generations, and across regions of the world? This study offers a new perspective based on the guiding ethics of sustainability and egalitarianism.

Sustainability is understood as a pattern of economic activity over time that sustains a given rate of growth of human welfare indefinitely. To achieve this, the atmospheric concentration of carbon must be capped at some level not much higher than exists today, and investments in education and research should be higher than they currently are. International cooperation between developing and developed nations is also vital, because economic growth and the climate problem are intertwined.

The authors propose that the guiding principle of bargaining should be that the dates at which developing countries’ living standards catch up with those of developed countries should not be altered by the agreement. They conclude that developed economies would have to agree not to exceed 1 percent growth in per capita GDP annually, while developing nations should grow at a faster rate, but still lower than current projections, until they converge. The authors acknowledge that achieving such a dramatic slowdown would carry political and economic challenges.

Theories of Distributive Justice
John E. Roemer
Harvard University Press, 1996

Equally at home in economic theory and political philosophy, John Roemer has written a unique book that critiques economists’ conceptions of justice from a philosophical perspective and philosophical theories of distributive justice from an economic one. He unites the economist’s skill in constructing precise, axiomatic models with the philosopher’s in exploring the assumptions of those models. His synthesis will enable philosophers and economists to engage each other’s ideas more fruitfully.

Roemer first shows how economists’ understanding of the fairness of various resource allocation mechanisms can be enriched. He extends the economic theory of social choice to show how individual preferences can be aggregated into social preferences over various alternatives. He critiques the standard applications of axiomatic bargaining theory to distributive justice, showing that they ignore information on available resources and preference orderings. He puts these variables in the models, which enable him to generate resource allocation mechanisms that are more consonant with our intuitions about distributive justice. He then critiques economists’ theories of utilitarianism and examines the question of the optimal population size in a world of finite resources.

Roemer explores the major new philosophical concepts of the theory of distributive justice—primary goods, functionings and capability, responsibility in its various forms, procedural versus outcome justice, midfare—and shows how they can be sharpened and clarified with the aid of economic analysis. He critiques and extends the ideas of major contemporary theories of distributive justice, including those of Rawls, Sen, Nozick, and Dworkin. Beginning from the recent theories of Arneson and G. A. Cohen, he constructs a theory of equality of opportunity. Theories of Distributive Justice contains important and original results, and it can also be used as a graduate-level text in economics and philosophy.
