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 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...

This paper shows that the supply side of credit is a major factor for the phenomenonof hampered interest rate pass-through in monopolistic banking markets. Our data,covering all 1,555 small and medium sized banks in Germany, provides a clear wayto partial out demand shocks; we are thus able to...

This paper examines empirically the relationship between innovation and market structure within a simultaneous framework at the industry level of aggregation. We use a model in which R&D affects both, demand and cost conditions. An optimization process leads to optimal industry R&D expenditure...

This paper proposes and empirically implements a framework for analyzing industry competition and the degree of joint profit maximization of merging firms in differentiated product industries. Using pre- and post-merger industry data, I am able to separate merging firms' intra-organizational...

One explanation provided for the relatively high and increasingly stable spreads for moderate - sized IPOs ($20-$80 million) documented in Chen and Ritter (2000) is that issuing firms focus less on price and more on a combination of investment bank-differentiating factors (such as underwriter...

We show that statistical tests of OPEC behavior have very low power across a wide range of alternative hypotheses regarding market structure. Consequently, it is difficult, given the current availability and precision of data on demand and costs, to distinguish collusive from competitive...

This paper investigates the effects of changes in market structure on residential service quality in local U.S. broadband markets. Our analysis focuses on identifying causal effects on quality from entry (or exit) by firms using both legacy and non-legacy broadband network technologies.We...

Most of the literature on retail fuel markets find high-frequency and asymmetric price cycles. This is typically explained by the model of Edgeworth price cycles. A key element of this model is that prices fall to marginal costs during a cycle. It seems challenging to address this assumption...

This study examines and compares characteristics, financing patterns, and performance outcomes of women-owned and men-owned young entrepreneurial firms. Using fully imputed data from the Kauffman Firm Surveys of U.S. start-up firms, we first examine the differences in firm and owner...
