A stylized macroeconomic model is developed with an indebted, heterogeneous Investment Banking Sector funded by borrowing from a retail banking sector. The government guarantees retail deposits. Investment banks choose how risky their activities should be. We find that the financial sector can...

A macroeconomic model is developed to analyse integration of retail and investment banks with and without deposit insurance. Benefits flow from elimination of double marginalization and insurance premia which retail banks otherwise charge investment banks. Deposit insurance increases average...

In this paper, we consider a model where producers set their prices based on their prediction of the aggregated price level and an exogenous variable, which can be a demand or a cost-push shock. To form their expectations, they use OLS-type econometric learning with bounded memory. We show that...

The aim of this paper is twofold. First, it provides a simple framework for the analyses of the transitions between two steady states with different fiscal policies. This allows us to clarify the existing results on the possibility of Pareto-improving transitions from pay-as-you-go to fully...

This article provides a simple proof of the Lorenz dominance criterion for two non-decreasing income transformations. The criterion is extended the most general case, with only very mild restrictions on the form of initial income distribution or the properties of the income transformations.

The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantative research. It is shown that it is generally possible to derive a linear-quadratic problem that approximates the exact non-linear porblem where the unconditional...
