Formulating a model comprising transportation, uncertainty and price, we describe how Web procurement is likely to boost volumes of international services vs. materials inputs. Using panel data for over 2,000 firms, we find that Web procurement increases international services outsourcing by...

Trade in intermediate goods as one possible link between rising trade and foreign direct investment is examined. To explain growing intermediate goods trade, three hypotheses are brought forward: outsourcing, global sourcing and the increasing importance of MNE networks. These hypotheses are...

We experimentally investigate purchase decisions with linear and nonlinear pricing under risk. The experiment is based on a single period stochastic inventory problem with endogenous cost. It extends classic binary lottery experiments to test standard decision theoretic predictions concerning...

Formulating a model which summarises transportation costs, uncertainty and price, we describe how a switch to ICT procurement can impact more readily procured services rather than materials. Uncertainty represents a catch-all factor describing the dovetailing of operations between two neither...

In multi-attribute procurement auctions with multiple objects, the auctioneer may care about the interplay of quality attributes that do not belong to the same item – like each item’s delivery time, if all items are needed at once. This can in?uence the performance of the auction mechanism....

When procurement contracts are awarded through competitive tendering participating firms commit ex ante to fulfil a set of contractual duties. However, selected contractors may find profitable to renege ex post on their promises by opportunistically delivering lower quality standards. In order...

A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by quality and sellers have private reserve prices for their items. Sellers quote prices strategically, inducing a knapsack game. The buyer's problem is to select a subset of maximal quality. We...

Ein Berater erfüllt einerseits die Rolle des Wissensvermittlers, andererseits kann er die Funktion übernehmen, bestehende Probleme und geplante Maßnahmen verschiedenen Interessensgruppen gegenüber zu legitimeren. Dieser Artikel zeigt empirische Evidenz für die Rolle des IT-Beraters auf...
