Why and in what ways have lawyers been importing economic theories into a legal environment, and how has this shaped scholarly research, judicial and legislative work? Since the financial crisis, corporate or capital markets law has been the focus of attention by academia and media. Formal modelling has been used to describe how capital markets work and, later, has been criticised for its abstract assumptions. Empirical legal studies and regulatory impact assessments offered different ways forward. This book presents a new approach to the risks and benefits of interdisciplinary policy work. The benefits economic theory brings for reliable and tested lawmaking are contrasted with important challenges including the significant differences of research methodology, leading to misunderstandings and problems of efficient implementation of economic theory's findings into the legal world. Katja Langenbucher's innovative research scrutinises the potential of economic theory to European legislators faced with a lack of democratic accountability.

The 2007 to 2009 financial crisis resulted in the re-emergence of the debate on financial regulation and its relationships with other macroeconomic policies, particularly monetary policy. In Europe, the financial crisis was followed by the sovereign debt crisis, as the bail-out of the financial sector put strains on public finances in several countries. The sequence of events called for a strengthening of the union, ranging from a common framework for supervisory policy that could minimize the risk of unforeseen bank or country defaults to a common resolution mechanism that could set equal rules across countries and reduce ex-ante mis-incentives to risk-taking and moral hazard. This analysis of the state of and prospects for financial regulation examines the lending and saving behavior of banks and households as well as their borrowing activities in order to understand the conflicting priorities and complicated decisions involved in the development and implementation of financial legislation.
