Trees and Matchings

open access: yes, 1999
In this article, Temperley's bijection between spanning trees of the square grid on the one hand, and perfect matchings (also known as dimer coverings) of the square grid on the other, is extended to the setting of general planar directed (and undirected)

Competitive diplomacy in bargaining and war

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract War is often viewed as a bargaining problem. However, prior to bargaining, countries can vie for leverage by expending effort on diplomacy. This article presents a dynamic model of conflict where agenda‐setting power is endogenous to pre‐bargaining diplomatic competition.

An extension of the basic local independence model to multiple observed classifications

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

How Can Inflation Contracts Discipline Central Bankers When Agents Are Learning?

open access: yesBulletin of Economic Research, EarlyView.
ABSTRACT This paper studies, in a new Keynesian model with a positive optimal output gap, how to design linear inflation contracts to shape the central bank's incentive structure when private expectations are based on adaptive learning. In this model, under rational expectations, inflation contracts could only partially deal with the time‐inconsistency

Late payments, higher prices? An experimental investigation of competitive procurement

open access: yesDecision Sciences, EarlyView.
Abstract The decision to pay one's supplier late is commonplace across global supply chains and, arguably, a key challenge for many businesses. In a multiple‐methods study, we contribute to the literature by documenting important empirical and anecdotal features about the likelihood and severity of late payments, formulating and solving a theoretical ...

Strategic Flip‐Flopping in Political Competition

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study candidates' position adjustments in response to information about voters' preferences. Repositioning allows candidates to move closer to the median voter, but it incurs financial and electoral costs. In a subgame‐perfect equilibrium, candidates diverge from the center ex ante if the costs of adjustment are sufficiently large.

Limit Orders and Knightian Uncertainty

open access: yesInternational Economic Review, EarlyView.
ABSTRACT A wide variety of financial instruments allows risk‐averse traders to reduce their exposure to risk. This raises the question of what financial instruments allow ambiguity‐averse traders to reduce their exposure to ambiguity. We show in this paper that price‐contingent orders, such as limit orders, are sufficient: In a two‐period trading model,

Evaluating Allocations of Opportunities

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper provides a robust criterion for comparing lists of probability distributions—interpreted as allocations of opportunities—faced by different social groups. We axiomatically argue in favor of comparing those lists of probability distributions on the basis of a uniform—among groups—valuation of their expected utility.

Vessel arrival planning with full information

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Planning efficiency and timely arrival of vessels is crucial to smooth operations of maritime transport networks, ensuring optimal utilization of resources and minimizing operational costs. Coordination between vessel operators and terminals has the potential to reduce costs, fuel consumption, and waiting time.

Artificial intelligence‐powered microscopy: Transforming the landscape of parasitology

open access: yesJournal of Microscopy, EarlyView.
Abstract Microscopy and image analysis play a vital role in parasitology research; they are critical for identifying parasitic organisms and elucidating their complex life cycles. Despite major advancements in imaging and analysis, several challenges remain. These include the integration of interdisciplinary data; information derived from various model
