James Friedman provides a thorough survey of oligopoly theory using numerical examples and careful verbal explanations to make the ideas clear and accessible. While the earlier ideas of Cournot, Hotelling, and Chamberlin are presented, the larger part of the book is devoted to the modern work on oligopoly that has resulted from the application of dynamic techniques and game theory to this area of economics. The book begins with static oligopoly theory. Cournot's model and its more recent elaborations are covered in the first substantive chapter. Then the Chamberlinian analysis of product differentiation, spatial competition, and characteristics space is set out. The subsequent chapters on modern work deal with reaction functions, advertising, oligopoly with capital, entry, and oligopoly using noncooperative game theory. A large bibliography is provided.

Few financial mathematical books have discussed mathematically acceptable boundary conditions for the degenerate diffusion equations in finance. In The Time-Discrete Method of Lines for Options and Bonds, Gunter H. Meyer examines PDE models for financial derivatives and shows where the Fichera theory requires the pricing equation at degenerate boundary points, and what modifications of it lead to acceptable tangential boundary conditions at non-degenerate points on computational boundaries when no financial data are available. Extensive numerical simulations are carried out with the method of lines to examine the influence of the finite computational domain and of the chosen boundary conditions on option and bond prices in one and two dimensions, reflecting multiple assets, stochastic volatility, jump diffusion and uncertain parameters. Special emphasis is given to early exercise boundaries, prices and their derivatives near expiration. Detailed graphs and tables are included which may serve as benchmark data for solutions found with competing numerical methods.

The largest, wealthiest corporations have gained unprecedented power and influence in contemporary life. From cradle to grave the decisions made by these entities have an enormous impact on how we live and work, what we eat, our physical and psychological health, what we know or believe, whom we elect, and how we deal with one another and with the natural world around us. At the same time, government seems ever more subservient to the power of these oligopolies, providing numerous forms of corporate welfare—tax breaks, subsidies, guarantees, and bailouts—while neglecting the most basic needs of the population. In Corporate Power, Oligopolies, and the Crisis of the State, Luis Suarez-Villa employs a multidisciplinary perspective to provide unprecedented documentation of a growing crisis of governance, marked by a massive transfer of risk from the private sector to the state, skyrocketing debt, great inequality and economic insecurity, along with an alignment of the interests of politicians and a new, minuscule but immensely wealthy and influential corporate elite. Thanks to this dysfunctional environment, Suarez-Villa argues, stagnation and a vanishing public trust have become the hallmarks of our time.

The global financial crisis brought public guarantees to the forefront of the policy debate. Based on a review of the theoretical foundations of public guarantees, this paper concludes that the commonly used justifications for public guarantees based solely on agency frictions (such as adverse selection or lack of collateral) and/or un-internalized externalities are flawed. When risk is idiosyncratic, it is highly unlikely that a case for guarantees can be made without risk aversion. When risk aversion is explicitly added to the picture, public guarantees may be justified by the state's natural advantage in dealing with collective action failures (providing public goods). The state can spread risk more finely across space and time because it can coordinate and pool atomistic agents that would otherwise not organize themselves to solve monitoring or commitment problems. Public guarantees may be transitory, until financial systems mature, or permanent, when risk is fat-tailed. In the case of aggregate (non-diversifiable) risk, permanent public guarantees may also be justified, but in this case the state adds value not by spreading risk but by coordinating agents. In addition to greater transparency in justifying public guarantees, the analysis calls for exploiting the natural complementarities between the state and the markets in bearing risk.

Labor markets are increasingly global. Overseas work can enrich households but also split them geographically, with ambiguous net effects on decisions about work, investment, and education. These net effects, and their mechanisms, are poorly understood. This study investigates a policy discontinuity in the Philippines that resulted in quasi-random assignment of temporary, partial-household migration to high-wage jobs in Korea. This allows unusually reliable measurement of the reduced-form effect of these overseas jobs on migrant households. A purpose-built survey allows nonexperimental tests of different theoretical mechanisms for the reduced-form effect. The study also explores how reliably the reduced-form effect could be measured with standard observational estimators. It finds large effects on spending, borrowing, and human capital investment, but no effects on saving or entrepreneurship. Remittances appear to overwhelm household splitting as a causal mechanism.

"General Equilibrium Theory: An Introduction presents the mathematical economic theory of price determination and resource allocation from elementary to advanced levels, suitable for advanced undergraduates and graduate students of economics. This Arrow-Debreu model (known for two of its most prominent founders, both Nobel Laureates) is the basis of modern price theory and of a wide range of applications. The text starts with elementary models: Robinson Crusoe, the Edgeworth Box, and a 2-commodity 2-household 2-firm model. It gives a brief introduction to the mathematics used in the field (continuity, convexity, separation theorems, Brouwer fixed-point theorem, point-to-set mappings, and Shapley-Folkman theorem). It then presents the mathematical general equilibrium model in progressively more general settings, including point-valued, set-valued, and non-convex set-valued demand and supply. Existence of general equilibrium, fundamental theorems of welfare economics, core convergence, and futures markets with time and uncertainty are treated fully. The new edition updates discussion throughout and expands the number and variety of exercises. It offers a revised and extended treatment of core convergence, including the case of non-convex preferences, and introduces the investigation of approximate equilibrium with U-shaped curves and non-convex preferences"--
