The German current account balance has moved from surplus to deßcit in the course of unificalion. A theorelical model for the current account, encompassing the elaslicities, the monetary, and the absorptions approach, is set up and lested for Germany and the United States, using cointegration...

Sustainable intensification of Ghana's smallholder farming is critical to mitigate rural poverty. Innovations for sustainable intensification include agro-ecological practices, which build up soil fertility, and mulching, which conserves soil moisture. To stimulate the adoption of these...

Combining a Dynamic Computable General Equilibrium (DCGE) model of the Yemeni economy with a microsimulation model that captures the link between changes in household incomes and changes in nutrition status, this paper provides a quantitative assessment of the agricultural, economy-wide, and...

Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level dataset on the foreign activities of German firms to test whether foreign...

We use the Factor-Augmented Vector Autoregression (FAVAR) approach of Bernanke, Boivin and Eliasz (2005) to estimate the effects of monetary policy shocks on wages and employment in the euro area. The use of a large data set comprising country, sectoral and euro area-wide data allows us to...

How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually...

In a series of summits, leading countries of the world will meet to draw up an international arrangement for financial stability. Such a rule system should prevent a financial crisis as we have seen it in 2007 and 2008. It should include appropriate principles of monetary policy, rules for...

Models with heterogeneous interacting agents explain macro phenomena through interactions at the micro level. We propose genetic algorithms as a model for individual expectations to explain aggregate market phenomena. The model explains all stylized facts observed in aggregate price fluctuations...

The literature has shown that product market frictions and firms dynamic play a crucial role in reconciling standard DSGE with several stylized facts. This paper studies optimal monetary policy in a DSGE model with sticky prices and oligopolistic competition. In this model firms' monopolistic...

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.
