may, on their own, generate monotone matching predictions in the absence of complementarities or anti-complementarities in production technology. We also derive sufficient conditions on the primitives of the model leading to the optimality of positive and negative matching of team members.

We study the dynamics of an oligopoly market with network externalities. In contrast to earlier work, we consider a model where products are vertically differentiated and the number of firms is arbitrary. We show that the degree of network externalities has a one-to-one relationship with the...

The Murrumbidgee River catchment is a major region of both dryland and irrigated agricultural production in eastern Australia. The salinity of water in the lower reaches of the river is the subject of concern; changing land management upstream is one option to minimise accessions of salt to the...

This paper presents a model of cumulative innovation where firms are heterogeneous in their research ability. We study the optimal reward policy when the quality of the ideas and their subsequent development effort are private information. The optimal assignment of property rights must...

The skill premium fell substantially in the first part of the 20th century and then rose at the end of the century. I argue that these changes are connected to the organization of production. When production is organized into large plants, jobs become routinized, favoring less-skilled workers. A...

In this paper we develop a theory of how factors interact at the plant level. The theory has implications for: (1) the micro foundations for capital skill complementarity (2) the relationship between factor allocation and plant size and (3) the effects of trade and growth on the skill premium....

Since 1914, the U.S. Senate has been elected and incumbent senators allowed to run for reelection without limit. This differs from several other elected offices in the U.S., which impose term limits on incumbents. Term limits may harm the electorate if tenure is beneficial or if they force high...

Since 1914, incumbent U.S. senators running for reelection have won almost 80% of the time. We investigate why incumbents win so often. We allow for three potential explanations for the incumbency advantage: selection, tenure, and challenger quality, which are separately identified using...
