Making, amending, and interpreting constitutions is a political game that can yield widespread suffering or secure a nation's liberty and prosperity. Given these high stakes, Robert Cooter argues that constitutional theory should trouble itself less with literary analysis and arguments over founders' intentions and focus much more on the real-world consequences of various constitutional provisions and choices. Pooling the best available theories from economics and political science, particularly those developed from game theory, Cooter's economic analysis of constitutions fundamentally recasts a field of growing interest and dramatic international importance.

By uncovering the constitutional incentives that influence citizens, politicians, administrators, and judges, Cooter exposes fault lines in alternative forms of democracy: unitary versus federal states, deep administration versus many elections, parliamentary versus presidential systems, unicameral versus bicameral legislatures, common versus civil law, and liberty versus equality rights. Cooter applies an efficiency test to these alternatives, asking how far they satisfy the preferences of citizens for laws and public goods.

To answer Cooter contrasts two types of democracy, which he defines as competitive government. The center of the political spectrum defeats the extremes in "median democracy," whereas representatives of all the citizens bargain over laws and public goods in "bargain democracy." Bargaining can realize all the gains from political trades, or bargaining can collapse into an unstable contest of redistribution. States plagued by instability and contests over redistribution should move towards median democracy by increasing transaction costs and reducing the power of the extremes. Specifically, promoting median versus bargain democracy involves promoting winner-take-all elections versus proportional representation, two parties versus multiple parties, referenda versus representative democracy, and special governments versus comprehensive governments.

This innovative theory will have ramifications felt across national and disciplinary borders, and will be debated by a large audience, including the growing pool of economists interested in how law and politics shape economic policy, political scientists using game theory or specializing in constitutional law, and academic lawyers. The approach will also garner attention from students of political science, law, and economics, as well as policy makers working in and with new democracies where constitutions are being written and refined.

Lawyers, judges, and scholars have long debated whether incentives in tort, contract, and restitution law effectively promote the welfare of society. If these incentives were ideal, tort law would reduce the cost and frequency of accidents, contract law would lubricate transactions, and restitution law would encourage people to benefit others. Unfortunately, the incentives in these laws lead to too many injuries, too little contractual cooperation, and too few unrequested benefits. Getting Incentives Right explains how law might better serve the social good. In tort law, Robert Cooter and Ariel Porat propose that all foreseeable risks should be included when setting standards of care and awarding damages. Failure to do so causes accidents that better legal incentives would avoid. In contract law, they show that making a promise often causes the person who receives it to change behavior and undermine the cooperation between the parties. They recommend several solutions, including a novel contract called "anti-insurance." In restitution law, people who convey unrequested benefits to others are seldom entitled to compensation. Restitution law should compensate them more than it currently does, so that they will provide more unrequested benefits. In these three areas of law, Getting Incentives Right demonstrates that better law can promote the well-being of people by providing better incentives for the private regulation of conduct.

Sustained growth depends on innovation, whether it's cutting-edge software from Silicon Valley, an improved assembly line in Sichuan, or a new export market for Swaziland's leather. Developing a new idea requires money, which poses a problem of trust. The innovator must trust the investor with his idea and the investor must trust the innovator with her money. Robert Cooter and Hans-Bernd Schafer call this the "double trust dilemma of development." Nowhere is this problem more acute than in poorer nations, where the failure to solve it results in stagnant economies.

In "Solomon's Knot," Cooter and Schafer propose a legal theory of economic growth that details how effective property, contract, and business laws help to unite capital and ideas. They also demonstrate why ineffective private and business laws are the root cause of the poverty of nations in today's world. Without the legal institutions that allow innovation and entrepreneurship to thrive, other attempts to spur economic growth are destined to fail."
