This paper studies the hedging effectiveness of interest rate swaps using different reference rates for eliminating interest rate risk from floating rate loans. Two different reference rates are studied. The first is a reference rate whose maturity, ∆, matches the payment interval of the...

This paper studies optimal index design to both facilitate hedging and alleviate illegal manipulation in a competitive equilibrium paradigm, modified to deal with manipulation. Specifically, a large trader is trading both derivatives and stocks, and effectively hides her trades behind the...

This paper models how chatroom traders, forming a coalition via social media platforms, influence the stock price in the presence of large and strategic short sellers. The economic consequences of this dynamic game are studied in a micro-founded quasi-competitive equilibrium framework, which is...

This paper studies the relation between concavity, stochastic or state dependent utility functions, and risk aversion. Using the common definition of risk aversion, but modified for state dependent preferences, we show that concavity does not imply risk aversion. Instead, it implies a weaker...

We model an influencer economy in which brand owners and sellers depend on influencers to attract consumers while competing in both influencer and product markets. As technologies governing marketing outreach improve, the equilibrium features non-monotonicities in influencer market...

We provide the first model of an influencer economy in which brand owners and sellers depend on influencers to attract consumers while competing in both influencer and product markets. As technologies governing marketing outreach improve, the equilibrium features non-monotonicities in influencer...

This paper derives an equilibrium asset pricing model with liquidity risk. Liquidity risk is modeled as a stochastic quantity impact on the price from trading, where the size of the impact depends on trade size. Under a mild set of assumptions, we prove that an equilibrium price process exists...

Based on a reduced-form model of credit risk, we explore mispricing in the CDS spreads of North American companies and its economic content. Specifically, we develop a trading strategy using the model to trade out of sample market-neutral portfolios across the term structure of CDS contracts....
