We establish a stochastic maximum principle (SMP) for control problems of partially observed diffusions of mean-field type with risk-sensitive performance functionals.

Published / Preprint: Risk minimization and portfolio diversification. (arXiv:1411.6657v1 [q-fin.PM])

Posted: 25 Nov 2014 05:30 PM PST

We consider the risk minimization problem, with capital at risk as the coherent measure, under the Black-Scholes setting. The problem is studied, when there exists additional correlation constraint between the desired portfolio and another financial index, and the closed form solution for the optimal portfolio is obtained. We also mention to variance reduction and getting better diversified...

Published / Preprint: On Trading American Put Options with Interactive Volatility. (arXiv:1411.6938v1 [q-fin.PR])

Posted: 25 Nov 2014 05:30 PM PST

We introduce a simple stochastic volatility model, which takes into account hitting times of the asset price, and study the optimal stopping problem corresponding to a put option whose time horizon (after the asset price hits a certain level) is exponentially distributed. We obtain explicit optimal stopping rules in various cases one of which is interestingly complex because of an unexpectedly...

Published / Preprint: Optimal Starting-Stopping and Switching of a CIR Process with Fixed Costs. (arXiv:1411.6080v1 [q-fin.MF])

Posted: 24 Nov 2014 05:37 PM PST

This paper analyzes the problem of starting and stopping a Cox-Ingersoll-Ross (CIR) process with fixed costs. In addition, we also study a related optimal switching problem that involves an infinite sequence of starts and stops. We establish the conditions under which the starting-stopping and switching problems admit the same optimal starting and/or stopping strategies. We rigorously prove that...

Published / Preprint: Identifying A Screening Model with Multidimensional Private Information. (arXiv:1411.6250v1 [q-fin.EC])

Posted: 24 Nov 2014 05:37 PM PST

In this paper I study nonparametric identification of a screening model when consumers have multivariate private information about their preferences. In particular, I consider the multiproduct nonlinear pricing model developed by Rochet and Chon\'e (1998), and determine conditions under which the cost function and the joint density of preferences are identified. When the utility function is...

Published / Preprint: On robust representation of conditional risk measures on a $L^\infty$-type module. (arXiv:1411.6256v1 [math.FA])

Posted: 24 Nov 2014 05:37 PM PST

The purpose of this paper is to establish a robust representation theorem for conditional risk measures by using a module-based convex analysis, where risk measures are defined on a $L^\infty$-type module. We define and study a Fatou property for this kind of risk measures, which is a generalization of the already known Fatou property for static risk measures. In order to prove this robust...

Published / Preprint: How Does Household Portfolio Diversification Vary with Financial Literacy and Financial Advice?

Posted: 24 Nov 2014 05:29 AM PST

Household investment mistakes are an important concern for researchers and policymakers alike. Portfolio underdiversification ranks among those mistakes that are potentially most costly. However, its roots and empirical importance are poorly understood. I estimate quantitatively meaningful diversification statistics and investigate their relationship with key variables. Nearly all households that...

Published / Preprint: Incentivizing Calculated Risk-Taking: Evidence from an Experiment with Commercial Bank Loan Officers

Posted: 24 Nov 2014 02:18 AM PST

We conduct an experiment with commercial bank loan officers to test how performance compensation affects risk assessment and lending. High-powered incentives lead to greater screening effort and more profitable lending decisions. This effect is muted, however, by deferred compensation and limited liability, two standard features of loan officer compensation contracts. We find that career concerns...

Published / Preprint: Investment Decisions of Nonprofit Firms: Evidence from Hospitals

Posted: 24 Nov 2014 01:46 AM PST

This paper examines investment choices of nonprofit hospitals. It tests how shocks to cash flows caused by the performance of the hospitals’ financial assets affect hospital expenditures. Capital expenditures increase, on average, by 10â€"28 cents for every dollar received from financial assets. The sensitivity is similar to that found earlier for shareholder owned corporations. Executive...

Published / Preprint: Defined Contribution Pension Plans: Sticky or Discerning Money?

Posted: 24 Nov 2014 01:46 AM PST

Participants in defined contribution (DC) retirement plans rarely adjust their portfolio allocations, suggesting that their investment choices and consequent money flows are sticky and not discerning. However, participants’ inertia could be offset by DC plan sponsors, who adjust the plan's investment options. We examine these countervailing influences on flows into U.S. mutual funds. We find...

In this paper we present a numerical valuation of variable annuities with combined Guaranteed Minimum Withdrawal Benefit (GMWB) and Guaranteed Minimum Death Benefit (GMDB) under optimal policyholder behaviour solved as an optimal stochastic control problem. This product simultaneously deals with financial risk, mortality risk and human behaviour. We assume that market is complete in financial...

Posted: 20 Nov 2014 05:37 PM PST

Here we present an application of two maxentropic procedures to determine the probability density distribution of compound sums of random variables, using only a finite number of empirically determined fractional moments. The two methods are the Standard method of Maximum Entropy (SME), and the method of Maximum Entropy in the Mean (MEM). We shall verify that the reconstructions obtained satisfy...

Posted: 20 Nov 2014 05:37 PM PST

This paper considers the optimal dividend payment problem in piecewise-deterministic compound Poisson risk models. The objective is to maximize the expected discounted dividend payout up to the time of ruin. We provide a comparative study in this general framework of both restricted and unrestricted payment schemes, which were only previously treated separately in certain special cases of risk...
