This paper derives and estimates rules for fiscal policy that prescribe the optimal response to changes in unemployment and debt. We combine the reducedform model of the economy from a linear VAR with a non-linear welfare function and obtain analytic solutions for optimal policy. The variables...

Most countries have automatic rules in their tax-and-transfer systems that are partly intended to stabilize economic fluctuations. This paper measures how effective they are. We put forward a model that merges the standard incomplete-markets model of consumption and inequality with the new...

This paper considers the economic and political drivers of sovereign default, focusing on countries rich enough to render sovereign default a ‘won’t pay’ rather than a ‘can’t pay’ phenomenon. Unlike many private contracts, sovereign debt contracts rely almost exclusively on...

Guided by theories of management by exception, we study the impact of Information and Communication Technology on worker and plant manager autonomy and span of control. The theory suggests that information technology is a decentralizing force, whereas communication technology is a centralizing...

The increased adoption of fertiliser and improved seeds are key to raising land productivity in Ethiopian agriculture. However, as in much of sub-Saharan Africa, the adoption and diffusion of such technologies has been slow. We use data from the Ethiopia between 1999-2009 to examine the role of...

The recovery from the last recession has been slower than any other recovery in the post-WWII period both in the US and in many other advanced economies. There is an ongoing debate around the causes of such a slow recovery. Are there any structural factors that are constraining the speed of...

Sovereign yield spreads within currency unions may reflect the risk of outright default. Yet, if exit from the currency union is possible, spreads may also reflect currency risk. In this paper, we develop a New Keynesian model of a small member country of a currency union, allowing both for...

The gravity equation in international trade is one of the most robust empirical finding in economics: bilateral trade between two countries is proportional to size, measured by GDP, and inversely proportional to the geographic distance between them. While the role of size is well understood, the...

Clusters have already been extensively shown to favor firm-level economic performance (productivity, exports, innovation etc.). However, little is known about the capacity of firms in clusters to resist economic shocks. In this paper, we analyze whether firms that agglomerate in clusters and...

The paper reports the result of an experimental game on asset integration and risk taking. We find evidence that winnings in earlier rounds affect risk taking in subsequent rounds, but no evidence that real life wealth outside the experiment affects risk taking. We find some evidence of...
