We develop a stochastic control model for an investor's optimal investment and consumption over an uncertain planning horizon when the investor is endowed with a defaultable time are prescribed by deterministic hazard rates, and the investor makes investments in a standard financial market with a bond and a stock, modeled by geometric Brownian motion. In addition, the investor purchases insurance against both default and the terminal date, the default insurance serving as a proxy for the investor's disutility for default. We approximate the original continuous-time problem with a sequence of discrete-time Markov chain control problems by applying dynamic programming and the Markov chain approximation. We demonstrate how the problem can be solved numerically through a logarithmic transformation of the investor's wealth variable, even when the utilities are CRRA with large risk aversion parameter. The model and computational approach are applied to a retiree's optimal annuity decision in the presence of default risk, and we demonstrate that default risk can lead a retiree to annuitize significantly smaller proportions of savings, even when a portion of the defaulted annuity can be recovered, than is traditionally considered optimal by the retirement-finance community. Hence, we show that credit risk may play an important role in resolving the annuity puzzle.

Included in this volume are the Invited Talks given at the 5th International Congress of Industrial and Applied Mathematics. The authors of these papers are all acknowledged masters of their fields, having been chosen through a rigorous selection process by a distinguished International Program Committee. This volume presents an overview of contemporary applications of mathematics, with the coverage ranging from the rhythms of the nervous system, to optimal transportation, elasto-plasticity, computational drug design, hydrodynamic and meteorological modeling, and valuation in financial markets. Many papers are direct products of the computer revolution: grid generation, multi-scale modeling, high-dimensional numerical integration, nonlinear optimization, accurate floating-point computations and advanced iterative methods. Other papers demonstrate the close dependence on developments in mathematics itself, and the increasing importance of statistics. Additional topics relate to the study of properties of fluids and fluid-flows, or add to our understanding of Partial Differential Equations.

We provide a systematic analysis of the properties of individual returns to wealth using twelve years of population data from Norway’s administrative tax records. We document a number of novel results. First, during our sample period individuals earn markedly different average returns on their financial assets (a standard deviation of 14%) and on their net worth (a standard deviation of 8%). Second, heterogeneity in returns does not arise merely from differences in the allocation of wealth between safe and risky assets: returns are heterogeneous even within asset classes. Third, returns are positively correlated with wealth: moving from the 10th to the 90th percentile of the financial wealth distribution increases the return by 3 percentage points - and by 17 percentage points when the same exercise is performed for the return to net worth. Fourth, wealth returns exhibit substantial persistence over time. We argue that while this persistence partly reflects stable differences in risk exposure and assets scale, it also reflects persistent heterogeneity in sophistication and financial information, as well as entrepreneurial talent. Finally, wealth returns are (mildly) correlated across generations. We discuss the implications of these findings for several strands of the wealth inequality debate.

"Magnificent."—The Economist From the Nobel Prize–winning economist, a groundbreaking and comprehensive account of corporate finance Recent decades have seen great theoretical and empirical advances in the field of corporate finance. Whereas once the subject addressed mainly the financing of corporations—equity, debt, and valuation—today it also embraces crucial issues of governance, liquidity, risk management, relationships between banks and corporations, and the macroeconomic impact of corporations. However, this progress has left in its wake a jumbled array of concepts and models that students are often hard put to make sense of. Here, one of the world's leading economists offers a lucid, unified, and comprehensive introduction to modern corporate finance theory. Jean Tirole builds his landmark book around a single model, using an incentive or contract theory approach. Filling a major gap in the field, The Theory of Corporate Finance is an indispensable resource for graduate and advanced undergraduate students as well as researchers of corporate finance, industrial organization, political economy, development, and macroeconomics. Tirole conveys the organizing principles that structure the analysis of today's key management and public policy issues, such as the reform of corporate governance and auditing; the role of private equity, financial markets, and takeovers; the efficient determination of leverage, dividends, liquidity, and risk management; and the design of managerial incentive packages. He weaves empirical studies into the book's theoretical analysis. And he places the corporation in its broader environment, both microeconomic and macroeconomic, and examines the two-way interaction between the corporate environment and institutions. Setting a new milestone in the field, The Theory of Corporate Finance will be the authoritative text for years to come.

The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.

The Global Monitoring Report 2014/2015: Ending Poverty and Sharing Prosperity was written jointly by the World Bank Group (WBG) and the International Monetary Fund, with substantive inputs from the Organisation for Economic Co-operation and Development. This year's report details, for the first time, progress toward the WBG's twin goals of ending extreme poverty by 2030 and promoting shared prosperity and assesses the state of policies and institutions that are important for achieving them. The report continues to monitor progress on the Millennium Development Goals (MDGs). Also for the first time, the report includes information about high-income countries. It finds that while gaps in living standards have been closing in many countries, the well-being of households in the bottom 40 percent, as measured by the non-income MDGs such as access to education and health services, remains below that of households in the top 60 percent. The focus of this year's report is on three elements needed to make growth more inclusive and sustainable: investment in human capital that favors the poor, the best use of safety nets, and steps to ensure the environmental sustainability of economic growth. These three elements are imperative to all countries' development strategies, and are also fundamental to global efforts to achieve the twin goals, the MDGs, and the Sustainable Development Goals that will succeed the MDGs. Global Monitoring Report 2014/2015 was prepared in collaboration with regional development banks and other multilateral partners.

The recent past has witnessed phenomenal growth in MFIs around the world. Today as many as 200 million people are beneficiaries of microfinance. Given its worldwide attention, microfinance has received serious criticism, including the argument that it is a fad with less-than-expected benefits for the poor. Surely, microfinance is not without any pitfalls. Yet the premise of improving access to financial services for consumption smoothing by the poor has never been a subject of controversy. What has been controversial is whether microfinance can alleviate poverty. That the poor lack an effective and affordable alternative financing mechanism to support income generation does not necessarily mean microfinance is a panacea since it involves entrepreneurial skills, which many poor lack. It is little wonder that studies evaluating the benefits of microfinance have produced conflicting results. Of course, study findings are contextual: They are positive in conducive environments and less so in unfavorable ones. Microfinance must be distinguished from anti-poverty schemes (e.g., conditional cash transfers) because benefits from microfinance-supported activities, which involve participants’ entrepreneurial skills and ability, take time to realize. This book using household long panel survey of 1991/92-2010/11 from Bangladesh addresses some of criticisms—including whether pushing microfinance has made it redundant as a tool for poverty reduction—while investigating whether it still matters for the poor after two decades of extensive growth. The book’s findings confirm the positive effects of continued borrowing from a microfinance program. Despite a manifold increase in microfinance borrowing, loan recovery has not declined and long-term borrowers are not trapped in poverty or debt. Interest rates charged by MFIs are not too high for realizing returns on investment, although the MFIs have scope for lowering them. The book is expected to contribute to the ongoing debate on the cost-effectiveness of microfinance as a tool for inclusive growth and development. It is expected to fill knowledge gaps in understanding the various virtues of microfinance against its portrayal as having drifted from its original poverty-reduction mission.

Saving rates vary considerably across countries and over time. Policies that spur development are an indirect but effective way to raise private saving rates, which rise with the level and growth rate of real per capita income.
