A folyó ráfordítások és tőkemérlegek együtthatóiból közelítőleg ki lehet számítani a növekedési rátát, az egyensúly arányait, valamint a fontosabb ciklusok tartamát és formáját. A tanulmány a diszkrét, illetve a folytonos idő kezelését, a ciklust keltő alapvető...

The crisis, in a dazzling way, shows not only that state regulation of financial activities is ineffective, but that political subordination of this activity, rather than an obligation to make a profit, thus creating a higher value than is consumed, leads, in the long term, to an unsustainable...

Cet article présente les contributions originelles et essentielles de T. Sargent et C. Sims à la modélisation macro-économétrique. Après avoir exposé leur critique de la modélisation existante, cet article s'attache à préciser l'originalité de leurs approches respectives. La...

There is a demand for safe assets, either government bonds or private substitutes, for use as collateral. Government bonds are safe assets, given the government's power to tax, but their supply is driven by fiscal considerations, and does not necessarily meet the private demand for safe assets....

Markov-switching DSGE (MSDSGE) modeling has become a growing body of literature on economic and policy issues related to structural shifts. This paper develops a general perturbation methodology for constructing high-order approximations to the solutions of MSDSGE models. Our new method, called...

What can history tell us about the relationship between the banking system, financial crises, the global economy, and economic performance? Evidence shows that in the advanced economies we live in a world that is more financialized than ever before as measured by importance of credit in the...

We propose a theory of monetary policy and macroprudential interventions in financial markets. We focus on economies with nominal rigidities in goods and labor markets and subject to constraints on monetary policy, such as the zero lower bound or fixed exchange rates. We identify an aggregate...

The recent financial crisis has highlighted the limits of the 'originate to distribute' model of banking, but its nexus with the macroeconomy and monetary policy remains unexplored. I build a DSGE model with banks (along the lines of Holmström and Tirole [28] and Parlour and Plantin [39] and...

In this paper, we first document that two predictions of the heterogeneous firm version of the Dornbusch (1987) pricing model are confirmed in micro data on US import prices: while the rate at which a firm reacts to changes in its own cost is U-shaped in market share, the rate at which it reacts...

Guided by a macroeconomic model in which non-energy commodity prices are endogenously determined, we apply a new factor-based identification strategy to decompose the historical sources of changes in commodity prices and global economic activity. The model yields a factor structure for commodity...
