WEFA combines practitioner experience with academic leadership to design and deliver expert solutions to complex problems.

WEFA Principal John Merrick 
has split his professional career between academia and Wall Street and brings eleven years of experience  in research, product management and proprietary trading in securities and derivative markets. His academic research program focuses on securities and commodities market frictions, asset and derivative contract valuation, and market manipulation.

WEFA Principal Vladimir Atanasov  consults with start-up companies, private equity funds and investment companies concerning equity valuation, private equity investment contracts, portfolio management, asset allocation and product development. He is an academic leader in applying higher standards of test design for making causal inferences regarding attribution of impacts and damages in financial settings (see “Shock-Based Causal Inference in Corporate Finance Research,” forthcoming in  Critical Finance Review).



Causal Inferences about Damages: Design Matters

Do financial intermediaries interact with customers who are attempting to execute a strategy to manipulate a market? If so, these financial intermediaries may share part of the blame for any damages caused. In such a case, a methodology to estimate the how much of total damages should be attributed to these intermediaries needs to be designed.  

In their paper, “Financial Intermediaries in the Midst of Market Manipulation: Did They Protect the Fool or Help the Knave?" (forthcoming in the Journal of Corporate Finance)WEFA Principals Atanasov and Merrick design "but for" platinum and palladium futures contract pricing benchmarks that separate the impacts of the manipulating customer's bang-the-close trades from those of NYMEX metals market floor traders whose actions produced noncompetitive prices. 

Such custom pricing benchmarks based on specific underlying market structure permits proper attribution of damages caused in a case with multiple actors.
