Procurement auctions and unit-price contracts

In competitive procurement auctions, bids often have the form of unit-price contracts (UPCs). We show that optimal bidding behavior in UPC auctions is typically non-monotonic, and therefore may lead to inefficient allocations. However, UPC auctions may still be desirable for the buyer when compared to efficient mechanisms such as the first-price auction. In a UPC auction, low types…

A short and intuitive proof of Marshall's rule

When the price of an input factor to a production process increases, then the optimal output level declines and the input is substituted by other factors. Marshall's rule is a formula that determines the own-price elasticity for one factor as a weighted sum of the elasticities of output market demand and factor substitution. This note offers a proof for Marshall's rule that…

Strategic technology partnering in high-velocity environments: lessons from a case study

Strategic technology alliances have received increased attention in the management literature. However, considerably less weight has been given to the study of this phenomenon in different environments and particularly in high velocity environments. This paper analyzes six cases of strategic technology partnerships in the mobile telephone industry. We investigate how, in high…

Weak and strong ties, individualism-collectivism, and the diffusion of technological knowledge

Despite the importance of gathering technological knowledge from external sources, many firms are not well-placed to collect information from beyond their own boundaries. Government policies designed to improve access to technological knowledge often encourage firms to develop strong ties with competitors, suppliers or customers. But although strong ties are valuable, especially when…

Combining socio-demographic and logistic factors to explain the generation and collection of waste paper

The aim of this paper is to develop a model predicting the collected amount of waste paper at the regional level of municipalities. Learning about the factors that influence the amount of collected paper is a prerequisite for the evaluation and reorganization of collection systems. We hypothesize that the amount of collected paper depends on both the waste potential and the factors…

DELI: an interactive new product development tool for the analysis and evaluation of market research data

This paper presents DELI, a new interactive tool for supporting new product development decisions. DELI addresses the `chicken and egg` problem in new product development: a product's features shape the way that the market is segmented and targeted, but that very segmentation/targeting itself determines which features the product needs to incorporate. It is very useful,…

Is Strong Reciprocity a Maladaptation? On the Evolutionary Foundations of Human Altruism

In recent years a large number of experimental studies have documented the existence of strong reciprocity among humans. Strong reciprocity means that people willingly repay gifts and punish the violation of cooperation and fairness norms even in anonymous one-shot encounters with genetically experimental evidence suggesting that ultimate evolutionary explanations of strong…

A Nation-Wide Laboratory - Examining trust and trustworthiness by integrating behavioral experimen

"Typically, laboratory experiments suffer from homogeneous subject pools and self-selection biases. The usefulness of survey data is limited by measurement error and by the questionability of their behavioral relevance. Here we present a method integrating interactive experiments and representative surveys thereby overcoming crucial weaknesses of both approaches. One of the…

A Product Market Theory of Worker Training

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each others’ trained employees and finally engage in imperfect product market competition. Equilibria with and without training, and multiple equilibria can emerge. If…
