We discuss the effects of AD-protection in a standard Dixit model of entry deterrence. In an AD-regime, the newcomer is constrained by a minimum-price rule in addition to existing irreversible entrance costs. For minimum prices which lie below the Stackelberg one, we find that AD-rules distort...

For a market of horizontal product differentiation, the paper examines the effects of the level of competition on the firm's decision between a product and process innovation. When firms have to choose between the two types of innovation, it is demonstrated that both firms undertake the product...

To solve boundary value problems for linear systems of stochastic differential equations we propose and justify a numerical method based on the Gibbs sampler. In contrast to the technique which yields for linear systems an "exact" numerical solution, the proposed method is simpler to generalize...

In this paper we propose an alternative explanation for the nature, sources and consequences of inflation rate differentials in a monetary union, such as EMU. To achieve this, we build on the new neoclassical synthesis (NNS) framework, recently advanced by Goodfriend (2002) and Goodfriend and...

This paper compares the welfare effects of anticipated and unanticipated cost-push shocks within the canonical New Keynesian model with optimal monetary policy. We find that, for empirically plausible degrees of nominal rigidity, the anticipation of a future cost-push shock leads to a higher...

The purpose of this paper is to show how to solve linear dynamic rational expectations models with anticipated shocks by using the generalized Schur decomposition method. Furthermore, we determine the optimal unrestricted and restricted policy responses to anticipated shocks. We demonstrate our...

The endorsement of expansionary fiscal packages has often been based on the idea that large multipliers can contrast rising unemployment. Is that really the case? We explore those issues in a New Keynesian model in which unemployment arises because of matching frictions. We compare fiscal...

In this paper we present a history-friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries. The model is history friendly, in that it attempts at replicating some basic, stylized qualitative features of the evolution of...

This study models producer protection legislation that would grant growers the right to claim damages (PPLD) if their contracts are prematurely terminated. In the absence of contracting frictions that prevent contractors from redesigning contracts to accommodate exogenous policy changes, PPLD...
