In 2014 he was elected a Fellow of the British Academy, the United Kingdom's national academy for the humanities and social sciences.

An inclusive legal positivist, Kramer argues in his book Where Law and Morality Meet that moral principles can enter into the law of any jurisdiction.

He contends that legal officials can invoke moral principles as laws for resolving disputes, and that they can also invoke them as threshold tests which ordinary laws must satisfy.

In opposition to many other theorists, Kramer argues that these functions of moral principles are consistent with all the essential characteristics of any legal system.

He is also a leading proponent of the legal positivist argument that law and morality are separable, arguing against the position of natural-law theory, which portrays legal requirements as a species of moral requirements.

According to him, even though the existence of a legal system in any sizeable society is essential for the realization of fundamental moral values, law is not inherently moral either in its effects or in its motivational underpinnings.

Influenced by the theories of Ronald Dworkin, Kramer is a moral realist who argues that "moral requirements are strongly objective" and that "the objectivity of ethics is itself an ethical matter that rests primarily on ethical considerations."

In his book Moral Realism as a Moral Doctrine, he claims that "[m]oral realism - the doctrine that morality is indeed objective - is a moral doctrine."

Unlike Dworkin, he believes that, although there is a determinately correct moral answer to most moral questions, there exists genuine moral indeterminacy in relation to some rare moral questions.

He also distances himself from Dworkin's defense of value monism.
