We correct and extend the results of Gans (2015) regarding the effects of net neutrality regulation on equilibrium outcomes in settings where a content provider sells its services to consumers for a fee. We examine both pricing and investment effects. We extend the earlier paper's result that...

The information system shall represent the support of the put on and of the simplification of rules and administrative procedures in order to ensure a broad and non-discriminatory public access to public services and also to reduce tariffs for these services, along with the operating costs and...

The emergence of dynamic supply chains has resulted in increased global competition and demand for greater product variety. The object of supply chain management is to deal effectively with materials flow, information flow, and financing flow of supply network in competitive, collaborative, and...

We determine optimal monetary policy under commitment in a forwardlooking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because...

We show how to use a simple perturbation method to solve non-linear rational expectation models. Drawing from the applied mathematics literature we propose a method consisting of series expansions of the non-linear system around a known solution. The variables are represented in terms of their...

This paper investigates the impact on the network growth of the level of merchant discount, the level of Multilateral Interchange Fee (MIF), and the consumers' and the merchants' awareness of positive network effects. In an artificial market, in which issuers and acquirers belong to the same...

Phenomena such as the Great Moderation have increased the attention of macro-economists towards models where shock processes are not (log-)normal. This paper studies a class of discrete-time rational expectations models where the variance of exogenous innovations is subject to stochastic regime...

We will present a model to compute a lower bound for the price of this option. The model, represented by a non-linear parabolic PDE, is implemented with finite elements in order to demonstrate the results with several derivatives from the European market.
