A psychological approach to individual differences in intertemporal consumption patterns

Brandstätter, Hermann; Güth, Werner - 1998

When people decide about saving and consumption across the various periods of their life time they take into account their life expectancy when comparing present and future needs and resources for satisfying them. The experimental design, applied at two sites (Humboldt-University at Berlin and...

Heterogeneous time preferences and interest rates : the preferred habitat theory revisited

Riedel, Frank - 1999

Habitat Theory of Modigliani and Sutch, a model for intertemporal preferences accounting for preferred habitats is proposed …. In a heterogeneous world, preferred habitats can explain humps in the yield curve. Agents with a long habitat prefer long … term bonds to shorter instruments as the Preferred Habitat Theory predicts. …

Fractional cointegration and tests of present value models

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

This paper tests the validity of Present Value (PV) models of stock prices by employing a two-step strategy for testing the null hypothesis of no cointegration against alternatives which are fractionally cointegrated. Monte Carlo simulations are conducted to evaluate the power and size...

Optimal consumption choice for ratchet investors

Riedel, Frank - 2001

The utility maximization problem of "ratchet investors" who do not tolerate any decline in their consumption rate is solved explicitly for all felicity functions in a Markovian framework which includes Brownian motion and Poisson processes as special cases. The optimal consumption plan turns out...

Non-time additive utility optimization : the case of certainty

Riedel, Frank; Bank, Peter - 1998

We study the intertemporal utility maximization problem for Hindy-Huang-Kreps utilities. Necessary and sufficient conditions for optimality are given. An explicit solution is provided for a large class of utility functions. In particular, the case of separable power utilities with a finite time...

Optimal consumption choice under uncertainty with intertemporal substitution

Bank, Peter; Riedel, Frank - 1999

We extend the analysis of the intertemporal utility maximization problem for Hindy-Huang-Kreps utilities reported in Bank and Riedel (1998) to the stochastic case. Existence and uniqueness of optimal consumption plans are established under arbitrary convex portfolio constraints, including both...

Existence and structure of stochastic equilibria with intertemporal substitution

Bank, Peter; Riedel, Frank - 2000

We prove existence of an Arrow-Debreu equilibrium when agents' preferences exhibit local substitution in the sense of Hindy, Huang, and Kreps (1992). Efficient allocations and supporting price functionals are identified and characterized. Under Hindy Huang Kreps preferences, equilibrium price...

Nonparametric specification testing for continuous-time models with application to spot interest rates

Hong, Yongmiao; Li, Haitao - 2002

We propose two nonparametric transition density-based speciÞcation tests for continuous-time diffusion models. In contrast to marginal density as used in the literature, transition density can capture the full dynamics of a diffusion process, and in particular, can distinguish processes with...

Internet based econometric computing

Härdle, Wolfgang; Horowitz, Joel - 1998

Modern econometrics requires implementation of highly specialized software. In contrast to mathematical arguments used in implementing new econometric techniques the corresponding software algorithms require specific platforms. The specialization of hardware and software, in fact, seriously...
