We consider the problem of determining a set of optimal tariffs for an agent in a network, who owns a subset of the arcs of the network, and who wishes to maximize his revenues on this subset from a set of clients that make use of the network.The general variant of this problem is NP-hard,...

This paper compares two approaches towards the empirical inertia of inflation and output. Two variants that produce persistence are added to a baseline DSGE model of sticky prices: 1) sticky information applied to firms, workers, and households; and 2) a backward-looking inflation indexation...

This paper presents evidence on the industry effects of bank lending in Germany and asks whether bank lending to single industries depends on industry-specific bank credit demand or on monetary policy as determinant of bank credit supply. To this end, we estimate individual bank lending...

This article builds on the call of various authors (e.g. George & Jones, 2000; Mitchell & James,2001; Rousseau & Fried, 2001) for a better representation of time in theory-building andresearch in organizational behavior (OB). It proposes a radical temporalist approach to the study of OB which combines a...

In this paper we consider the two-machine ow shop problem with varying machine speeds. We present an algorithm which determines the optimal permutations for all machine speeds in O ( n log n ) time, where n is the number of jobs. To achieve this bound on the running time, the algorithm employs...

This paper investigates the relationship between corporate culture and market orientation using a different methodology to those usually found done in empirical studies on this topic. Conventionally, one or two key informants provide information on the firm’s marketing practices in large scale...

First, we investigate the minimal order univariate representation of some well known n-dimensionalconditional volatility models. Even simple low order systems (e.g. a multivariate GARCH(0,1)) forthe joint behavior of several variables imply individual processes with a lot of persistence inthe...

We consider machine scheduling problems where jobs have to be processed on unrelated parallel machines in order to minimize the schedule makespan. The processing time of any job is dependent on the usage of a scarce resource that can be distributed over the jobs in process. The more of that...

Domains of individual preferences for which the well-known impossibility theorems of Gibbard-Satterthwaite and Muller-Satterthwaite do not hold are studied. To comprehend the limitations these results imply for social choice rules, we search for the largest domains that are possible. Here, we...

In 1920, when Hayek was a student, he wrote a manuscript on cognitive psychology, which was published in 1952 as The Sensory Order. From the 1920s to the early 1940s Hayek developed his business cycle theory. The perceptions of economic agents play a central part in this theory. Contrary to what...
