We propose a new class of voting rules, called Size Approval Voting. According to this rule, the effective weight of a vote from a given individual depends on how many other alternatives the very same individual votes for. In particular, weights are assumed to be non-negative and weakly...

In 1848 freedom of press was written into the Constitution of the Kingdom of the Netherlands. This paper investigates the expected life span of daily newspapers in the Netherlands since then. Life expectancy depends on the cyclical evolution of the number of daily newspapers through time. The...

Decision making typically requires judgements about causal relations. We need to know both the causal effects of our actions and the causal relevance of various environmental factors. Judgements about the nature and strength of causal relations often differ, even among experts. How to handle...

We analyze strategic firm behavior in settings where the production stage is followed by several periods during which only sales take place. We analyze the dynamics of the market structure, the development of prices and sales over time, and the implications for profits and consumer surplus. Two...

A set of agents with different waiting costs have to receive a service of different length of time from a single provider which can serve only one agent at a time. One needs to form a queue and set up monetary transfers to compensate the agents who have to wait. We prove that no rule satisfies...

This study develops a new bias-corrected estimator for the fixed-effects dynamic panel data model and derives its limiting distribution for fixed T and N large. The bias-corrected estimator is derived as a bias correction of the least-squares dummy variable (within) estimator. It does not share...

Condorcet''s famous jury theorem reaches an optimistic conclusion on the correctness of majority decisions, based on two controversial premises about voters: they are competent and vote independently, in a technical sense. I carefully analyse these premises and show that: (i) whether a premise...

In this paper, we compare the cause and effect of immaterial rewards and sanctions oncooperation in a voluntary contributions experiment. We find that both rewards andsanctions increase contributions only when subjects interact repeatedly, though rewardsseem to be more effective than sanctions....
