The globalization of capital and product markets has many implications for economic welfare. Countries can specialize in the production of goods for which they have comparative advantages, and capital is allocated more efficiently. However, one potentially adverse effect of globalization is the...

Stylized facts suggest that output volatility in OECD countries has declined in recent years. However, the causes and the nature of this decline have so far been analyzed mainly for the United States. In this paper, we analyze whether structural breaks in the dynamics and the volatility of the...

This paper discusses whether the integration of international financial markets affects business cycle fluctuations. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock....

The process of European integration has gained considerable momentum during the past couple of years. This paper provides an assessment of the degree of integration of both the accession states of central and eastern Europe and of the pre-ins for monetary union with respect to Germany. Using...

Does the mere presence of big banks affect macroeconomic outcomes? Gabaix (2011) shows that idosyncratic shocks can have aggregate effects if the distribution of firm sizes in manufacturing follows a power law distribution. Our contribution is two-fold. First, we expand the theory of granularity...

Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix (2008a) and construct a measure of...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...

Does the structure of banking markets affect macroeconomic volatility and, if yes, is this link different in low-income countries? Banking markets in low-income countries differ from those in developed market economies. Banking systems in lower-income countries are typically smaller and less...

Aggregated output in industrialized countries has become less volatile over the past decades. Whether this "Great Moderationʺ can be found in firm level data as well remains disputed. We study the evolution of firm level output volatility using a balanced panel dataset on German firms that...
