This paper examines the evolution of market structure in emerging market banking systems during the 1990s. While significant bank consolidation has been taking place in these countries, reflected in a sharp decline in the number of banks, this process has not systematically been associated with...

This paper studies two new models in which banks face a non-trivial asset allocation decision. The first model (CVH) predicts a negative relationship between banks' risk of failure and concentration, indicating a trade-off between competition and stability. The second model (BDN) predicts a...

This study investigates the impact of financial sector reforms on interest rate spreads in the commercial banking system in Malawi. The financial reform program commenced in 1989 when both the Reserve Bank Act and the Banking Act were revised with the easing of entry requirements into the...

This paper develops a model of political regulation in which politicians set the regulated price in order to maximize electoral support by signaling to voters a pro-consumer behavior. Political incentives and welfare constraints interact in the model, yielding an equilibrium in which the real...

Developing countries apply numerous sector-specific taxes to telecommunications, whose buoyant revenues and formal enterprises provide a convenient 'tax handle'. This paper explores whether there is an economic rationale for sector-specific taxes on telecommunications and, if so, what form they...

This paper presents a new version of MAPMOD (Mark II) to study the effectiveness of macroprudential regulations. We extend the original model by explicitly modeling the housing market. We show how household demand for housing, house prices, and bank mortgages are intertwined in what we call a...

This paper analyzes the effects of product market reforms in the short and medium term across 10 regulated industries and 18 advanced economies for the period 1998-2013 using internationally comparable firm-level data based on Orbis. It provides four key insights. First, product market reforms...

The paper investigates the economic effects of major product market reforms in some of the historically most protected non-manufacturing industries. It relies on a unique mapping between new annual data on reform shocks and sector-level outcomes for five network industries (electricity and gas,...

The choice of infrastructure delivery through public versus private provision is driven by investment and operational efficiency, and cost of capital differentials. While the first two factors are measurable --- albeit with mixed results --- the appropriate discount rate instigates...

We examine the extent to which regulations of entry and credit access are related to competition using data on 28 manufacturing sectors across 64 countries. A robust finding is that bureaucratic and costly entry regulations tend to hamper competition, as proxied by the price-cost margin, in the...
