Laurent-Emmanuel Calvet (born 28 February 1969) is a French economist and a professor of finance. He is Vice President Elect of the European Finance Association. [1]

Contents

Calvet is a Professor of Finance at SKEMA Business School. He previously held faculty positions at Harvard University, HEC Paris, and Imperial College London, and EDHEC Business School.

Calvet is a founding member of the Centre for Economic Policy Research's Household Finance Research Network. [2] He serves on the Advisory Scientific Committee of the European Systemic Risk Board. [3]

Early years

Calvet was born on 28 February 1969. He attended Lycée Janson de Sailly and Lycée Louis-le-Grand in Paris. He obtained engineering degrees from École Polytechnique in 1991 and École des ponts ParisTech in 1994. [4] [5] [6] He went on to complete his M.A., M.Phil. and Ph.D. (1998) in economics from Yale University. [7]

Academic career

Calvet served as an assistant professor and then as the John Loeb associate professor of the Social Sciences at Harvard University from 1998 to 2004. He taught finance at HEC Paris from 2004 to 2016, Imperial College London from 2007 to 2008, and EDHEC Business School from 2016 to 2023. [8] Specialist in asset pricing, household finance, and volatility modelling, Laurent Calvet joined SKEMA Business School in 2023 as a professor of finance.

In 2006, Calvet received the “Best Finance Researcher under the Age of 40” award from Le Monde and the Europlace Institute of Finance. [9] [10]

Contributions

Calvet is known for his research in financial economics, household finance, and econometrics. He pioneered with Adlai Fisher the Markov switching multifractal model of financial volatility, [11] [12] which is used by academics and financial practitioners to forecast volatility, compute value-at-risk, and price derivatives. [13] [14] [15] [16] This approach is summarized in the book “Multifractal Volatility: Theory, Forecasting and Pricing” (2008). [17]

In a 2007 publication, [18] Laurent E. Calvet, John Y. Campbell and Paolo Sodini show that households hold well-diversified portfolios of financial assets, consistent with the predictions of portfolio theory. This result confirms a key assumption of the Capital asset pricing model. Subsequent work confirms that household follow other important precepts of financial theory, such as portfolio rebalancing [19] and habit formation. [20]

Calvet has also contributed to statistical filtering theory. [21] He developed with Veronika Czellar and Elvezio Ronchetti robust filtering techniques that can withstand model misspecifications and outliers. [22] The robust filter naturally solves the degeneracy problem that plagues the particle filter of Gordon, Salmond, and Smith [23] and its many extensions.

Benoit B.Mandelbrot was a Polish-born French-American mathematician and polymath with broad interests in the practical sciences, especially regarding what he labeled as "the art of roughness" of physical phenomena and "the uncontrolled element in life". He referred to himself as a "fractalist" and is recognized for his contribution to the field of fractal geometry, which included coining the word "fractal", as well as developing a theory of "roughness and self-similarity" in nature.

Finance refers to monetary resources and to the study and discipline of money, currency, assets and liabilities. As a subject of study, it is related to but distinct from economics, which is the study of the production, distribution, and consumption of goods and services. Based on the scope of financial activities in financial systems, the discipline can be divided into personal, corporate, and public finance.

<span class="mw-page-title-main">Markov chain</span> Random process independent of past history

A Markov chain or Markov process is a stochastic process describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. Informally, this may be thought of as, "What happens next depends only on the state of affairs now." A countably infinite sequence, in which the chain moves state at discrete time steps, gives a discrete-time Markov chain (DTMC). A continuous-time process is called a continuous-time Markov chain (CTMC). Markov processes are named in honor of the Russian mathematician Andrey Markov.

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.

Financial modeling is the task of building an abstract representation of a real world financial situation. This is a mathematical model designed to represent the performance of a financial asset or portfolio of a business, project, or any other investment.

Financial risk modeling is the use of formal mathematical and econometric techniques to measure, monitor and control the market risk, credit risk, and operational risk on a firm's balance sheet, on a bank's accounting ledger of tradeable financial assets, or of a fund manager's portfolio value; see Financial risk management. Risk modeling is one of many subtasks within the broader area of financial modeling.

Statistical finance is the application of econophysics to financial markets. Instead of the normative roots of finance, it uses a positivist framework. It includes exemplars from statistical physics with an emphasis on emergent or collective properties of financial markets. Empirically observed stylized facts are the starting point for this approach to understanding financial markets.

In finance, volatility is the degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns.

In financial econometrics, the Markov-switching multifractal (MSM) is a model of asset returns developed by Laurent E. Calvet and Adlai J. Fisher that incorporates stochastic volatility components of heterogeneous durations. MSM captures the outliers, log-memory-like volatility persistence and power variation of financial returns. In currency and equity series, MSM compares favorably with standard volatility models such as GARCH(1,1) and FIGARCH both in- and out-of-sample. MSM is used by practitioners in the financial industry to forecast volatility, compute value-at-risk, and price derivatives.

Quantitative analysis is the use of mathematical and statistical methods in finance and investment management. Those working in the field are quantitative analysts (quants). Quants tend to specialize in specific areas which may include derivative structuring or pricing, risk management, investment management and other related finance occupations. The occupation is similar to those in industrial mathematics in other industries. The process usually consists of searching vast databases for patterns, such as correlations among liquid assets or price-movement patterns.

Macro risk is financial risk that is associated with macroeconomic or political factors. There are at least three different ways this phrase is applied. It can refer to economic or financial risk found in stocks and funds, to political risk found in different countries, and to the impact of economic or financial variables on political risk. Macro risk can also refer to types of economic factors which influence the volatility over time of investments, assets, portfolios, and the intrinsic value of companies.
