This paper studies welfare effects of a soft borrowing constraint on sovereign debt. The constraint is modeled as a proportional fine per unit of debt in excess of a specified reference value, resembling features of the Stability and Growth Pact. Sovereign debt is the result of myopic fiscal...

This paper proposes a reduced form model of dynamic duopoly in the context of heterogeneous innovations framework. Two agents invest into expansion of variety of available products and into the improvement of quality of existing products simultaneously. Every newly introduced product has its own...

Empirical evidence has shown that exporters are more capital intensive than non-exporters. Based on this evidence, I construct a two-factor general equilibrium model with firm heterogeneity in factor intensities, monopolistic competition, scale economies and international trade. This setting can...

A defined contribution pension plan allows consumption to be redistributed from the plan member's working life to retirement in a manner that is consistent with the member's personal preferences. The plan's optimal funding and investment strategies therefore depend on the desired profile of...

We propose a method to compute equilibria in dynamic models with several continuous state variables and occasionally binding constraints. These constraints induce non-differentiabilities in policy functions. We develop an interpolation technique that addresses this problem directly: It locates...

In this paper we show the impact of considering jumps in the return process of risky assets when deciding how to invest and consume throughout time. Agents derive their utilities from consumption over time. We consider an agent that invests in the financial market and in durable and perishable...

Micro evidence indicates that each period a fraction of prices is kept unchanged under a positive trend inflation rate. In a sticky price model based on this evidence, recent research shows that high trend inflation is a serious cause for indeterminacy of rational expectations equilibrium under...

In this paper we investigate the optimal harvesting of a renewable natural resource. While in most standard approaches the resource is located at a single point, we allow the resource to be distributed spatially. Consequently, an agent who exploits the resource has to travel from one location to...

In response to the Great Financial Crisis, the Federal Reserve, the Bank of England and many other central banks have adopted unconventional monetary policy instruments. We investigate if one of these, purchases of long-term government debt, could be a valuable addition to conventional...

A number of studies sought to measure the effects of non-standard policy on bank funding markets. This paper carries those estimates a step further by looking at the effects of bank funding market stress on the volume of bank lending. By separately modeling loan supply and demand, we determine...
