The effects of endogenous undiversifiable investment and market structure changes on security pricing are analyzed within the GEI-CAPM (General Equilibrium with Incomplete Markets Capital Asset Pricing Model). Both the mutual fund and security market line theorems are extended conditional to a...

Several models of intra-household decision making have been suggested in the literature. We present a framework that includes all suggested models and variants as special cases. We derive the theoretical predictions of these models for the relationship between expenditures on goods and the...

In the present paper, the existence of maximal elements for binary relations are studied. Generalized lexicographic relations are introduced, and some results on existence of maximal elements are provided. A simple example shows that economies with "lexicographic consumers" need not have...

The notions of instrument, intermediate target and final target are defined in the context of the cointegrated VAR. A target variable is said to be controllable if it can be made stationary around a desired target value by using the instrument. This can be expressed as a condition on the...

The long-run and short-run structure of the Danish manufacturing export sector is analyzed within a cointegrated vector autoregressive model. The price variables of the analysis can be characterized as integrated of second order, I(2), but long-run homogeneity seems to cancel the I(2)-trend...

The partial adjustment model for cigarette demand in Tansel (1993) is formulated as a restriction on the more general VAR model. The question whether the Tansel estimation results are spurious as claimed by Cameron and Collins (1998) is addressed in this framework. The role of intervention...

Exploiting a district level data set on the 2007/8 post-election violence in Kenya, this paper investigates why polarization between ethnic groups results in violent conflict in some cases, but not in others. After the announcement of highly controversial election results in December 2007,...

Within a production theoretic framework, this paper considers an axiomatic approach to benchmark selection. It is shown that two simple and weak axioms: efficiency and comprehensive monotonicity characterize a natural family of benchmarks which typically becomes unique. Further axioms are added...

This paper develops a model of simple 'reputation systems' that monitor and publish information about the behavior of sellers in a market with search frictions and asymmetric information. The reputations created by these systems influence the equilibrium search investments of buyers and thus...

Two firms selling a homogenous product to two types of buyers are involved in a sequential pricing game with zero costs. The pricing strategy available involves a fixed price and a royalty. It is shown that there exists a unique subgame perfect equilibrium with positive profits to both firms if...
