This paper provides the proofs to the analysis of a continuous time matching model with saving in Bayer and Wälde (2010a). The paper proves the results on consumption growth, provides an existence proof for optimal consumption and a detailed derivation of the Fokker-Planck equations. --...

We explore effects of simultaneous price changes for the demand of a group of goods, which we refer to as a compound commodity. Specifically, we consider unit and proportional cost components (e. g., taxes, transportation costs, etc.) imposed on the compound commodity. We find that there is a...

I study whether saving behavior reveals socially relevant intertemporal preferences. To this end, I decompose the present generation’s preference for the next into its dynastic and cross-dynastic components in a model of saving. If people are concerned about the next generation as such, then...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...

We examine the investment decision problem of a group whose members have heterogeneous time preferences. In particular, they have different discount factors for utility, possibly not exponential. We characterize the properties of efficient allocations of resources and of shadow prices that would...

This paper re-examines the issues involved in the design of a direct tax on consumption, an idea that has received a fair degree of acceptance in the transition countries over the past decade (e.g., tax reforms in Croatia and Moldova). First we argue that on the subject of equivalence among a...

This paper studies a married couple s dynamic investment and consumption choices under the assumption that the couple cannot commit across time not to renegotiate their decisions. The inefficiencies that can arise are characterized. Efficiency properties of different divorce asset-division...

In this paper we consider a risk averse worker who is moving back and forth between employment and unemployment; layoffs are random and beyond the worker s influence, while the re-employment chance is directly affected by search effort. We characterize the worker s optimal savings and job-search...

We characterize intertemporal utility functions over heterogeneous goods that feature (i) a constant elasticity of substitution between goods at each point in time and (ii) a constant intertemporal elasticity of substitution for at least one of the goods. We find that a standard (stationary)...
