Earlier studies found little evidence of scale economies at large banks; later studies using data from the 1990s uncovered such evidence, providing a rationale for very large banks seen worldwide. Using more recent data, the authors estimate scale economies using two production models. The...

The unique capital structure of commercial banking – funding production with demandable debt that participates in the economy’s payments system – affects various aspects of banking. It shapes banks’ comparative advantage in providing financial products and services to informationally...

The Great Recession focused attention on large financial institutions and systemic risk. We investigate whether large size provides any cost advantages to the economy and, if so, whether these cost advantages are due to technological scale economies or too-big-to-fail subsidies. Estimating scale...

Self regulation encouraged by market discipline constitutes a key component of Basel II’s third pillar. But high-risk investment strategies may maximize the expected value of some banks. In these cases, does market discipline encourage risk-taking that undermines bank stability in economic...

In perfectly competitive markets, prices aggregate inputs and outputs into a money metric that allows production plans to be ranked by their profitability. When informational asymmetries in competitive markets lead to adverse selection, prices in these markets assume an additional role that...

Great strides have been made in the theory of bank technology in terms of explaining banks’ comparative advantage in producing informationally intensive assets and financial services and in diversifying or offsetting a variety of risks. Great strides have also been made in explaining sub-par...

The authors argue for a shift in the focus of modeling production from the traditional assumptions of profit maximization and cost minimization to a more general assumption of managerial utility maximization that can incorporate risk incentives into the analysis of production and recover...

Using modern duality theory to recover technologies from data can be complicated by the risk characteristics of production. In many industries, risk influences cost and revenue and can create the potential for costly episodes of financial distress. When risk is an important consideration in...
