In this paper we study the problem of a city that is surrounded by two shopping centres. The first has low transport costs but is easily congested (near city center, access by road). The second one has higher transport costs but is less prone to congested access (ample public transport capacity...

There has been a very large amount of research devoted to the study of activity patterns. The initial studies have been developed in geography (space and time description of human activity, as described by Torsten, Hägerstrand and Peter Hagget) and in economics (starting with the seminal work...

People who anticipate the introduction of a policy can adapt their behavior, perhaps in ways that make the policy ineffective and exacerbate the problem to be addressed. This paper develops a political economy model to study strategic behavior related to the introduction of congestion policies,...

Consider a principal who appoints an agent. Let the agent potentially serve for a sufficiently long time that one principal is replaced by another over this period. Suppose also that the quality of the agent appointed increases with the effort the incumbent principal devotes to hiring. Then the...

Consider a public project which produces a consumption good and which benefits future generations. Let a conventional cost-benefit analysis find that it gives higher benefits than projects it would dis-place in the private sector. Voters may nevertheless oppose the public project: the...

Reduced inequality in human capital may reduce appropriationfrom the rich. They may therefore favor policies such as incometransfers and mandatory schooling which equalize human capital.Comparing several such policies, we find that mandatory schooling leads to higher incomes for both the rich...

We consider a firm that is subject to employment protection laws that limit the firm's ability to fire labor. In particular, we suppose that though a firm which shuts down can fire all its workers, it may fire no fewer. Compared to a firm that is subject to no employment protection, a firm...

We consider duopolists innovating and producing a good subject to network externalities, so that the reservation price of a consumer increases with aggregate consumption. The post-innovation network consists of two compatible sub-networks, with increased network valuation of the new product....

We consider taxation by a Leviathan government and by a utilitarian government in the presence of heterogeneous locations within a country, when migration from one country to another is and is not possible. In a closed economy, a utilitarian government may transfer income from the poor to the...

Corporate success stories often resemble a snowball. We show how initial luck in hiring talented people, the resulting technological advantage, superior corporate culture, and statusseeking by workers and by consumers can make small initial differences generate large differences over time.
