Persistent shifts in equilibria are likely to arise in oligopolistic markets and may be detrimental to the measurement of conduct, related markups and intensity of competition. We develop a cointegrated VAR (vector autoregression) based approach to detect long-run changes in conduct when data...

The paper investigates the existence and extent of economies of scale in depository and settlement systems. Evidence from 16 settlement institutions across different regions for the years 1993–2000 indicates the existence of significant economies of scale. The degree of such economies,...

This is the first paper that examines economies of scale in stock exchanges. The data employed in the study include cost and output statistics for 37 stock exchanges in four continents around the world for the year 1997. I estimate two traditional cost functions and find that ray (overall) scale...

This paper investigates the existence and extent of economies of scale and scope among stock exchanges. Evidence from 38 exchanges in 32 countries and 4 continents around the world for the years 1989-1998 indicates the existence of significant economies of scale and scope. The degree of such...

European nations substitute between employment protection regulations and labor market expenditures (e.g., unemployment insurance benefits) for providing worker insurance. Employment regulations more directly tax firms making frequent labor adjustments than other labor market insurance...

Motivated by the U.S. events of the 2000s, we address whether a too low for too long interest rate policy may generate a boom-bust cycle. We simulate anticipated and unanticipated monetary policies in state-of-the-art DSGE models and in a model with bond financing via a shadow banking system, in...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

This paper models the effects of financial development on economic growth through better or more efficient utilization of technological innovations. The model is based on the endogenous growth theory of Aghion and Howitt and its derivatives, especially the growth model of Aghion, Howitt and...

This paper tests for the presence of a credit channel (particularly a bank-lending sub-channel) for monetary policy in the housing market. We argue that the importance of this channel for investment in residential housing is highly dependent on the structural features, and particularly the...
