Contents

He is the author of numerous research articles, [3] and several books, [4] including Futures Markets, Dynamic Asset Pricing Theory, [5] and—with Kenneth SingletonCredit Risk. [6]

Education

He holds a Ph.D. (1984) in Engineering Economic Systems from Stanford University, a Master of Economics (1980) from the University of New England (Australia), and a Bachelor of Science in Engineering (Civil Engineering) (1975) from the University of New Brunswick. [7]

Career

Duffie has been on the finance faculty at Stanford since 1984. He is a Fellow and member of the Council of the Econometric Society, a Research Associate of the National Bureau of Economic Research, a member of the Financial Advisory Roundtable of the Federal Reserve Bank of New York, and a Fellow of The American Academy of Arts and Sciences. He was the President of The American Finance Association for 2009. He has served on the editorial board of many journals, including Econometrica . In 2003, Duffie was awarded the SunGard/IAFE Financial Engineer of the Year Award from the International Association of Financial Engineers.

In 2014, Duffie chaired the Market Participants Group, charged by the Financial Stability Board with recommending reforms to Libor, Euribor, and other interest rate benchmarks. He is a co-author of the proposal for Across-the-Curve Credit Spread Index ("AXI") and its extension Financial Conditions Credit Spread Index ("FXI") but has no related compensation and has no affiliation with their operationalization. AXI and FXI are forward looking benchmark credit spreads that can be used in conjunction with the Secured Overnight Financing Rate (“SOFR”) to form a credit sensitive interest rate benchmark. The spreads were launched in 2022 and are published and administered by Invesco Indexing LLC, an independent index provider owned by global asset manager Invesco Ltd.

In finance, default is failure to meet the legal obligations of a loan, for example when a home buyer fails to make a mortgage payment, or when a corporation or government fails to pay a bond which has reached maturity. A national or sovereign default is the failure or refusal of a government to repay its national debt.

Financial economics is the branch of economics characterized by a "concentration on monetary activities", in which "money of one type or another is likely to appear on both sides of a trade". Its concern is thus the interrelation of financial variables, such as share prices, interest rates and exchange rates, as opposed to those concerning the real economy. It has two main areas of focus: asset pricing and corporate finance; the first being the perspective of providers of capital, i.e. investors, and the second of users of capital. It thus provides the theoretical underpinning for much of finance.

In finance, an interest rate swap (IRS) is an interest rate derivative (IRD). It involves exchange of interest rates between two parties. In particular it is a "linear" IRD and one of the most liquid, benchmark products. It has associations with forward rate agreements (FRAs), and with zero coupon swaps (ZCSs).

Credit risk is the possibility of losing a lender holds due to a risk of default on a debt that may arise from a borrower failing to make required payments. In the first resort, the risk is that of the lender and includes lost principal and interest, disruption to cash flows, and increased collection costs. The loss may be complete or partial. In an efficient market, higher levels of credit risk will be associated with higher borrowing costs. Because of this, measures of borrowing costs such as yield spreads can be used to infer credit risk levels based on assessments by market participants.

In finance, a swap is an agreement between two counterparties to exchange financial instruments, cashflows, or payments for a certain time. The instruments can be almost anything but most swaps involve cash based on a notional principal amount.

Floating rate notes (FRNs) are bonds that have a variable coupon, equal to a money market reference rate, like SOFR or federal funds rate, plus a quoted spread. The spread is a rate that remains constant. Almost all FRNs have quarterly coupons, i.e. they pay out interest every three months. At the beginning of each coupon period, the coupon is calculated by taking the fixing of the reference rate for that day and adding the spread. A typical coupon would look like 3 months USD SOFR +0.20%.

An asset-backed security (ABS) is a security whose income payments, and hence value, are derived from and collateralized by a specified pool of underlying assets.

Fixed-income arbitrage is a group of market-neutral-investment strategies that are designed to take advantage of differences in interest rates between varying fixed-income securities or contracts. Arbitrage in terms of investment strategy, involves buying securities on one market for immediate resale on another market in order to profit from a price discrepancy.

In finance, a currency swap is an interest rate derivative (IRD). In particular it is a linear IRD, and one of the most liquid benchmark products spanning multiple currencies simultaneously. It has pricing associations with interest rate swaps (IRSs), foreign exchange (FX) rates, and FX swaps (FXSs).

The Jarrow–Turnbull model is a widely used "reduced-form" credit risk model. It was published in 1995 by Robert A. Jarrow and Stuart Turnbull. Under the model, which returns the corporate's probability of default, bankruptcy is modeled as a statistical process. The model extends the reduced-form model of Merton (1976) to a random interest rates framework.

The following outline is provided as an overview of and topical guide to finance:

Probability of default (PD) is a financial term describing the likelihood of a default over a particular time horizon. It provides an estimate of the likelihood that a borrower will be unable to meet its debt obligations.

Relative valuation also called valuation using multiples is the notion of comparing the price of an asset to the market value of similar assets. In the field of securities investment, the idea has led to important practical tools, which could presumably spot pricing anomalies. These tools have subsequently become instrumental in enabling analysts and investors to make vital decisions on asset allocation.

The Merton model, developed by Robert C. Merton in 1974, is a widely used "structural" credit risk model. Analysts and investors utilize the Merton model to understand how capable a company is at meeting financial obligations, servicing its debt, and weighing the general possibility that it will go into credit default.
