We study the stability of the no-arbitrage property under model uncertainty. We measure model uncertainty with the total variation distance of underlying probability distributions. We show that sufficiently small changes of the underlying probability distribution preserve the no-arbitrage...

Mainstream macro-models have assumed away financial frictions, in particular default. The minimum addition in order to introduce financial intermediaries, money and liquidity into such models is the possibility of default. This, in turn, requires that institutions and price formation mechanisms...

In this paper we propose a novel way to model the labor market in the context of a New-Keynesian general equilibrium model, incorporating labor market frictions in the form of hiring and firing costs. We show that such a model is able to replicate many important stylized facts of the business...

Emissions trading mechanisms have been proposed, and in some cases implemented, as a tool to reduce pollution. We explore the similarities between emission-trading mechanisms and monetary mechanisms. Both attempt to implement desirable allocations under various frictions, including risk and...

This article considers the empirical record of the 1942-1951 period of Federal Reserve history when the Fed was more politically accountable and more independent of private financial interests. During the 1940s, federal spending was nearly twice as high as today, and federal borrowing was more...

The main focus of the present paper is to analyze the impacts of financial policy on inflation rates. The analysis depended on time series data and was divided into theoretical and applied analytical framework. An econometric model was utilized to reflect the relations between financial policy...

The present paper aims to analyze impacts of financial policy on the foreign currencies exchange rates. The study utilizes time series data analyses in order to reach better econometric model that may reflect the relationship between financial policy and foreign exchange rates in Sudan between...

This Article focuses on the U.S. Federal Reserve's controversial practice of loaning U.S. dollars to foreign central banks, which the foreign central banks then turn around and loan to institutions in their jurisdictions. The Federal Reserve does not know the identity of these recipient...
