The paper estimated the degree of competitiveness and the main driving forces of the inherent market structure of the Nigerian banking industry. This is with a view to determining the structural implications of recent financial reforms on the banking sector in Nigeria. A unique contribution of...

Bank market power shapes firm investment and financing dynamics and hence affects the transmission of macroeconomic shocks. Motivated by a secular increase in the concentration of the US banking industry, I study bank market power through the lens of a dynamic general equilibrium model with...

The interbank network, in which banks compete with each other to supply and demand differentiated financial products, fulfils an important function but may also result in risk propagation. We examine this trade-off by setting out a model in which banks form interbank network links endogenously,...

We introduce endogenous participation of market makers into a Kyle-type model with long-lived asymmetric information. The main result is that under a plausible parameter setting, the trading volume and price volatility show a U-shape with respect to time, meaning that the market trading...

This study proposes a tractable imperfectly competitive economy where traders are socially connected with each other via an information network. We investigate the impact of information linkages on market equilibrium outcomes. In the linear-quadratic-normal framework, we establish the existence...

In a standard financial market model with asymmetric information with a finite number N of risk-averse informed traders, competitive rational expectations equilibria provide a good approximation to strategic equilibria as long as N is not too small: equilibrium prices in each situation converge...
