When the transmission channel between savers and borrowing firms is disturbed, firms may find themselves borrowing-constrained. I study the optimal fiscal policy response to a tightening borrowing constraint in a simple two-period model. I find that it is not optimal to subsidize firms, although...

In this paper, we study how lower corporate tax rates impact investment by including two novel channels into a DSGE model used for fiscal policy analysis in Norway. We capture both how foreign firms relocate and invest in the country when corporate taxes are reduced and how the inflow of FDI...

I offer a macroeconomic perspective on the "Reserves for All" (RFA) proposal to let the general public use electronic central bank money. After distinguishing RFA from cryptocurrencies and relating the proposal to discussions about narrow banking and the abolition of cash I propose an...

We find empirical evidence of a financial accelerator using a data based procedure of Structural Model Design. Credit to firms, asset prices and aggregate economic activity interact over the business cycle in our empirical model of a dynamic economy. Furthermore, the interdependence between...

The paper compares the welfare properties of two competing organizations of the monetary system: The current fractional reserve banking system versus a narrow banking system where inside money is fully backed by outside money issued by the central bank. Using a New Monetarist model, the analysis...

We analyze policy in a two-tiered monetary system. Noncompetitive banks issue deposits while the central bank issues reserves and a retail CBDC. Monies differ with respect to operating costs and liquidity. We map the framework into a baseline business cycle model with "pseudo wedges" and derive...

We analyze retail central bank digital currency (CBDC) in a two-tier monetary system with bank deposit market power and externalities from liquidity transformation. Resource costs of liquidity provision determine the optimal monetary architecture and modified Friedman (1969) rules the optimal...

This paper is published as Chapter 7 of Handbook of Microsimulation Modelling edited by Cathal O''Donoghue, and issued in the series Contributions to Economic Analysis by Emerald Publishing Group. The purpose of the paper is to provide a detailed discussion in relation to the development of the...

This paper examines regulation in the presence of adjustment costs and resource scarcity, allowing for imperfectly informed firms. I find strong evidence that announcement of future environmental regulation will reduce current emissions in the combined presence of resource scarcity and...

A tax on fuel combined with tax-exemptions or subsidies for purchase of fuel-efficient vehicles is implemented in many countries to reduce greenhouse gas emissions and other negative externalities from road traffic. This study, however, shows that a tax on fuel should be combined with heavier...
