This paper investigates the effects of rule-based prudential policies on the banks competition in the deposit market. Using the imperfect competition structure and focusing on heterogeneous banks, we develop a partial equilibrium model, under which implications of how capital adequacy ratio regulation is implemented either discriminatory between banks (micro) or non-discriminatory and uniformly for all banks (macro) will be analyzed. Among the features that are emphasized in this analytical model is the role of self-regulation of bank capital in building confidence in the banking network in a non-linear manner. This, in a range of capital adequacy ratios, has featured the use of that prudential policy tool as a self-defeating one for the policymaker's goal in curbing the portion of high-risk projects in the targeted bank's assets portfolio. Further, a channel to explain the role of monetary policy in establishing stability or fragility of the banking network is introduced. In particular, the role of investors' degree of risk aversion in motivating banks to set their monitoring efforts has been evaluated.

This paper takes a novel perspective in analyzing theoretically how the sovereign wealth funds (SWFs) would impact on the sovereign risk, and thereby, the financial sector and, due to some frictions, the real sector of its owner economy. This happens as we suggest SWFs could help in mitigating the extant financial markets incompleteness. In a standard dynamic (continuous time) stochastic partial equilibrium model, it is shown how the SWFs would, under certain conditions, mitigate its owner sovereign risk, in which case it leads to the possibility of impacting on external financing costs of financial intermediaries and corporate sector. In particular, we explore how the sensitivity of default and/or financial distress and/or debt restructuring against (domestic and/or foreign) adverse shocks to the economy would be less, when there is a SWF in the economy in comparison with when the economy lacks it. This is investigated for two sources of financing the SWF. Further, we argue how the costs and benefits of establishing the SWF would be affected by the (relative) size of SWF, its type, and the state of the financial (surplus) capacity in time of setting up the SWF. The externality associated with the establishment of the SWF for the sovereign risk and formation of the new channel for the transmission of monetary and fiscal policies have been examined too. Mutual interactions between the SWF and the monetary and fiscal policy within the analytical framework have been analyzed as well.
