Perceptions of organizational downsizing
This paper uses cognitive dissonance theory as a foundation for developing hypotheses about how past experience as a layoff agent influences respondents' perceptions of organizational downsizing. Consistent with many theoretical frameworks in organization studies, cognitive dissonance is conceptualized as an unmeasured construct that mediates between layoff agency and…

A dynamic segmentation approach for targeting and customizing direct marketing campaigns
An important aspect of customer relationship management is the targeting of customer segments with tailored promotional activities. While most contributions focus on the selection of promising customers for targeting, only few authors address the question of which specific differential offers to direct to the selected target groups. We focus on both issues and propose a flexible, two…

Using revealed preferences to infer environmental benefits, evidence from recreational fishing licenses
We develop and apply a new method for estimating the economic benefits of an environmental amenity. The method is based upon the notion of estimating the derived demand for a privately traded option to utilize an open access good. In particular, the demand for state fishing licenses is used to infer the benefits of recreational fishing. Using panel data on state fishing license sales…

The impact of bank consolidation on commercial borrower welfare
We estimate the impact of bank merger announcements on borrowers' stock prices for publicly traded Norwegian firms. Borrowers of target banks lose about 0.8% in equity value, while borrowers of acquiring banks earn positive abnormal returns, suggesting that borrower welfare is influenced by a strategic focus favoring acquiring borrowers. Bank mergers lead to higher relationship…

Strategic behavior and underpricing in uniform price auctions: Evidence from finnish treasury auctions
We contribute to the debate on the optimal design of multiunit auctions by developingand testing robust implications of the leading theory of uniform price auctions on the bid distributions submitted by individual bidders. The theory, which emphasizes market power, has little support in a data set of Finnish Treasury auctions. A reason may be that the Treasury acts strategically by…

Comment on William C. Brainard and Herbert E. Scarf's "How to Compute Equilibrium Prices in 1891"
Bill and Herb have provided an illuminating and interesting presentation of Irving Fisher's Ph.D. dissertation Mathematical Investigations in the Theory of Value and Prices. They correctly emphasize that Fisher's fundamental contribution to the early theory of general equilibrium was the construction of a machine to compute the equilibrium quantities in a Walrasian model of…

Divisible good auctions: the role of allocation rules
We examine the role of allocation rules in determining the set of equilibrium prices in uniform- price auctions. Beginning with Wilson (1979), the theoretical literature has argued that these auctions are subject to possible low equilibrium prices. We show that this is due to the way the asset is being divided. We focus on allocation rules that specify the way the asset is divided in…

Underpricing and market power in uniform price auctions
In uniform auctions, buyers chosse demand schedules as strategies and the same "market clearing" price for units awarded. Despite the widespread use of these auctions, the extant theory shows that they are susceptible to arbitrarily large underpricing. We make a realistic modification to the theory by letting prices, quantities, and bids be discrete. We show that…

Stationary Markov equilibria for overlapping generations
At a stationary Markov equilibrium of a Markovian economy of overlapping generations, prices at a date-event are determined by the realization of the shock, the distribution of wealth and, with production, the stock of capital. Stationary Markov equilibria may not exist; this is the case with intra-generational heterogeneity and multiple commodities or long life spans. Generalized…

Testable implications of general equilibrium theory: A differentiable approach
Is general equilibrium theory empirically testable? Our perspective on this question differs fromthe standard, Sonnenschein–Debreu–Mantel (SDM) viewpoint. While the SDM tradition considersaggregate (excess) demand as a function of prices, we suppose that what is observable is the equilibriumprice vector as a function of the fundamentals of the economy.We apply this perspective to…

Is intertemporal choice theory testable?
Kreps–Porteus preferences constitute a widely used alternative to time separability. We showin this paper that with these preferences utility maximization does not impose any observable restrictions on a household’s savings decisions or on choices in good markets over time. The additional assumption of a weakly separable aggregator is needed to ensure that the assumption of utility…
