In most of the contract theory literature, contracting costs are assumed either to be high enough to preclude certain forms of contracting, or low enough to permit any contract to be written. Similarly, researchers usually treat renegotiation as either costless or prohibitively costly. This...

This paper presents a theory of dynamic trade agreements in which external institutions, such as the WTO, play a central role in supporting credible enforcement. In our model, countries engage in ongoing negotiations, and as a consequence cooperative agreements become unsustainable in the...

We show how hard evidence can be incorporated into the mechanism-design framework. We provide a link between real evidence and abstract declarations, which clarifies when the abstract-declaration environment, which was first studied in Green and Laffont's (1986) "limited verifiability" analysis,...

This paper develops a macroeconomic model in which investable assets flow to entrepreneurs through long-term relationships with lenders. Low asset flows cause relationships to break up due to insufficient liquidity. Multiple Pareto ranked steady states emerge from complementarity between...

This paper develops a theoretical framework for analyzing contracting imperfections in long-term employment relationships. We focus chiefly on limited enforceability and limited worker liquidity. Inefficient severance of employment relationships, payment of efficiency wages, the relative...

This paper evaluates a class of endogenous job destruction models based on how well they explain the observed experiences of displaced workers. We show that pure reallocation models in which relationship-specific productivity drifts downward over time are difficult to reconcile with the evidence...

Motivated by a characteristic way in which firms in developed countries make their decisions regarding cooperation with potential partners from less developed countries, we design a simple model of a DC firm's search for an LDC partner/supplier and the subsequent relationship between the two...

Motivated by evidence on the importance of incomplete information and networks in international trade, we investigate the supply of 'network intermediation.' We hypothesize that the agents who become international trade intermediaries first accumulate networks of foreign contacts while working...

Contract interpretation is an important subject for lawyers but there are few rigorous economic analyses. We use a formal model to derive the interpretive rule that an “ideal” legal enforcer would adopt. Commercial parties make contracts to maximize gains from trade. Our enforcer is ideal,...
