This paper studies the consequence of an imprecise recall of the price by the consumers in the Bertrand price competition model for a homogeneous good. It is shown that firms can exploit this weakness and charge prices above the competitive price. This markup increases for rougher recall of the...

This paper suggests that contingent on the productivity level of the trade partner; international trade may create resource misallocation in less productive countries. It theoretically shows how productivity spillovers induced by trade with more productive countries and heterogeneity in...

The single crossing assumption simplifies the analysis of screening models as local incentive compatibility becomes sufficient for global incentive compatibility. If single crossing is violated, global incentive compatibility constraints have to be taken into account. This paper studies monotone...

This paper generalizes Porter's notion of the value chain for the analysis of service industries. The generalization entails that the flow and the physical transformation and assembly of goods that are characteristic of manufacturing are generalized into flows and transformation of data and...

This paper suggests that contingent on the productivity level of the trade partner; international trade may create resource misallocation in less productive countries. It theoretically shows how the interaction between technology diffusion induced by trade and cross sectoral heterogeneity in...

How do banks react to increased competition? Recent banking theory offers conflicting predictions about the impact of competition on bank orientation - i.e., the choice of relationship based versus transactional banking. We empirically investigate the impact of interbank competition on bank...

We extend the three-step generalized methods of moments (GMM) approach of Kapoor, Kelejian, and Prucha (2007), which corrects for spatially correlated errors in static panel data models, by introducing a spatial lag and a one-period lag of the dependent variable as additional explanatory...

To accommodate the inhomogenous character of financial time series over longer time periods, standard parametric models can be extended by allowing their coefficients to vary over time. Focusing on conditional heteroscedasticity models, we discuss various strategies to identify and estimate...

We propose a class of distribution-free rank-based tests for the null hypothesis of a unit root. This class is indexed by the choice of a reference density g, which needs not coincide with the unknown actual innovation density f. The validity of these tests, in terms of exact finite sample size,...

In a Gaussian, heterogeneous, cross-sectionally independent panel with incidental intercepts, Moon, Perron, and Phillips (2007) presents an asymptotic power envelope yielding an upper bound to the local asymptotic power of unit root tests. In case of homogeneous alternatives this envelope is...
