Franklin Allen and Douglas Gale have contributed substantially to the study of financial innovation, developing economic models to address the question of whether the market provides institutions and opportunities for individuals to share risks efficiently.
Financial systems are crucial to the allocation of resources in a modern economy. They channel household savings to the corporate sector and allocate investment funds among firms; they allow intertemporal smoothing of consumption by households and expenditures by firms; and they enable households and firms to share risks. These functions are common to the financial systems of most developed economies. Yet the form of these financial systems varies widely. Why do different countries have such different financial systems? Is one system better than all the others?
These original essays focus on a wide range of topics related to Frank Hahn's distinguished work in economics. Ranging from market analysis and game theory to the microeconomic foundations of macroeconomics and from equilibrium and optimality with missing markets to economics and society, they reflect the diversity of modem research in economic theory. What distinguishes Hahn's work and many of the essays in this book is that the motivation often comes from practical concerns about unemployment, savings and investment, poverty, or the stability of markets.
