We present an efficiency wage model in which workers'' effort depends on the level and on the growth rate of their wage relative to an alternative wage. Using data for four countries (US, UK, FR, GY), the implications of the model are examined and are found to be in accordance with the...

The industrial organization of transactions has changed dramatically during the past decade (Thompson and Wright, 1988). Several scholars have discussed and documented the phenomenon of what has been called `the shrinking organization'' (Ford and Farmer, 1986; Lichtenberg, 1992). The apparent...

An impossibility theorem for preference aggretating rules is discussed. In this theorem no transitivity condition or acyclicity condition is imposed on the preferences: neither on the individual level nor on the aggregated level. Under the conditions that aggregation is non-dictatorial,...

Technological innovations and growing consumer demand have led to a variety of design and expansion problems in telecommunication networks. In particular, local access net- works have received a lot of attention, since they account for approximately 60% of total investments in communication...

Sign-compatible dynamics describe changes in the composition of a population driven by differences in fitness. A saturated equilibrium is a fixed point for sign-compatible dynamics where each subgroup with positive population share has highest fitness. An evolutionary stable equilibrium is a...

Network formation within the BRITE-EURAM program is investigated. We describe the role of the hub of the network, which is defined as the set of main contractors that account for most of the participations. We study the effects that the conflict of objectives within European research funding...

We consider the problem of (re)allocating the total endowment of an infinitely divisible commodity among agents with single-peaked preferences and initial endowments. We propose an extension of the so-called uniform rule and show that it is the unique rule satisfying strategy-proofness, Pareto...

We consider the problem of reallocating the total initial endowments of an infinitely divisible commodity among agents with single-peaked preferences. With the uniform reallocation rule we propose a solution which satisfies many appealing properties, describing the effect of population and...
