Complexity and uncertainty define our world, now more than ever. Scholars and practitioners celebrate modular contract design as an especially effective tool to manage these challenges. Modularity divides complex structures into relatively discrete, independent components with simple...

This paper examines the role of the third party (the IMF) in resolving sovereign default on external debt. We first show that the effects of third party intervention in debt negotiations are quite sensitive to the assumed enforcement mechanism for sovereign debt. The model is then adapted to an...

The possibility of default limits available liquidity. If the potential default draws nearer, a liquidity crisis may ensue, causing a crash in asset prices, even if the probability of default barely changes, and even if no defaults subsequently materialize. Introducing default and limited...

Recently, Blanchard and Kremer (BK) argued that disorganization has led to the output decline in the former Soviet Union. In this paper we introduce liquidity and credit constraints into the BK model and show how these problems can alleviate the hold-up problem. We argue further that barter...

Since the fall of communism, the former Soviet Union experienced a strong output decline and a dramatic increase in arrears and barter. We develop a model which explains how these three phenomena are connected. We introduce liquidity and credit constraints into a model of disorganization and...
