Parametric estimation: Finite sample theory

Spokoiny, Vladimir - 2011

The paper aims at reconsidering the famous Le Cam LAN theory. The main features of the approach which make it different … results are illustrated for the i.i.d. set-up as well as for generalized linear and median estimation. The results apply for …

Every symmetric 3 x 3 global game of strategic complementarities is noise independent

Basteck, Christian; Daniëls, Tijmen R. - 2010

We prove that the global game selection in all 3 x 3 payoff-symmetric supermodular games is independent of the noise structure. As far as we know, all other proofs of noise independence of such games rely on the existence of a so-called monotone potential (MP) maximiser. Our result is more...

CRRA utility maximization under risk constraints

Moreno-Bromberg, Santiago; Pirvu, Traian A.; … - 2011

This paper studies the problem of optimal investment with CRRA (constant, relative risk aversion) preferences, subject to dynamic risk constraints on trading strategies. The market model considered is continuous in time and incomplete; furthermore, financial assets are modeled by Itô processes....

Solving DSGE models with a nonlinear moving average

Lan, Hong; Meyer-Gohde, Alexander - 2011

We introduce a nonlinear infinite moving average as an alternative to the standard state-space policy function for solving nonlinear DSGE models. Perturbation of the nonlinear moving average policy function provides a direct mapping from a history of innovations to endogenous variables,...

Forward-backward systems for expected utility maximization

Horst, Ulrich; Hu, Ying; Imkeller, Peter; Réveillac, … - 2011

In this paper we deal with the utility maximization problem with a general utility function. We derive a new approach in which we reduce the utility maximization problem with general utility to the study of a fully-coupled Forward-Backward Stochastic Differential Equation (FBSDE).

The real consequences of financial stress

Mittnik, Stefan; Semmler, Willi - 2013

We introduce a dynamic banking-macro model, which abstains from conventional mean-reversion assumptions and in which - similar to Brunnermeier and Sannikov (2010) - adverse asset-price movements and their impact on risk premia and credit spreads can induce instabilities in the banking sector. To...
