Coherent price systems and uncertainty-neutral valuation : conference paper

Beißner, Patrick - 2013 - This version: 28 February, 2013

We consider fundamental questions of arbitrage pricing arising when the uncertainty model incorporates volatility … uncertainty. With a standard probabilistic model, essential equivalence between the absence of arbitrage and the existence of an … martingale measure sets, in a dynamic trading framework under absence of prior depending arbitrage. We prove the existence of …

Asset Pricing with Countercyclical Household Consumption Risk

Constantinides, George M. - 2015

We present evidence that shocks to household consumption growth are negatively skewed, persistent, countercyclical, and drive asset prices. We construct a parsimonious model where heterogeneous households have recursive preferences. A single state variable drives the conditional cross-sectional...

Collateralized Borrowing and Increasing Risk

Phelan, Gregory - 2016

This paper uses a general equilibrium model with collateralized borrowing to show that increases in risk can have ambiguous effects on leverage, loan margins, loan amounts, and asset prices. Increasing risk about future payoffs and endowments can lead to riskier loans with larger balances and...

Option-Based Pricing of Wrong Way Risk for CVA

Kenyon, Chris - 2016

The two main issues for managing wrong way risk (WWR) for the credit valuation adjustment (CVA, i.e. WW-CVA) are calibration and hedging. Hence we start from a novel model-free worst-case approach based on static hedging of counterparty exposure with liquid options. We say "start from" because...

Unsecured Credit Supply Risk and Bond Prices

Mabille, Pierre - 2021

Changes in credit supply induce large and frequent variations in households' access to unsecured debt. They generate a novel financial precautionary motive, which compounds the classical motive associated with idiosyncratic income risk, as borrowers accumulate risk-free bonds to hedge against...

Dynamic Equilibrium with Heterogeneous Agents and Risk Constraints

Prieto, Rodolfo - 2011

We examine the impact of risk-based portfolio constraints on asset prices in an exchange economy. Constrained agents scale down their portfolio and behave locally like power utility investors with risk aversion that depends on current market conditions. The imposition of constraints dampens...

Asset pricing and consumption-portfolio choice with recursive utility and unspanned risk

Kraft, Holger; Seiferling, Thomas; Seifried, Frank Thomas - 2014 - First version: March 6, 2014; this version: June 1, 2014

We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential...

Risks to Human Capital

Ebrahimian, Mehran - 2020

Do financing constraints deepen recessions? To help answer this question, we build a model with inalienable human capital, in which investors finance individuals who can potentially become skilled. Though investment in skill is always optimal, it does not take place in some states of the world,...

The financial origins of non-fundamental risk

Acharya, Sushant; Dogra, Keshav; Singh, Sanjay R - 2021

We formalize the idea that the financial sector can be a source of non-fundamental risk. Households' desire to hedge against price volatility can generate price volatility in equilibrium, even absent fundamental risk. Fearing that asset prices may fall, risk-averse households demand safe assets...
