The paper analyses the fiscal effects of productivity shifts in the private sector. Within a stylized model with inelastic labour supply, it shows that productivity shifts in sectors producing non-traded goods (N-sector) are irrelevant for the tax rates necessary to meet the government budget...

We present a model for an energy market that includes a green certificate for suppliers of energy from renewables and a purchaser commitment to buy these certificates. We show that price and volume effects in the energy market are ambigous under a wide range of alternative levels of the...

The Norwegian pension reform of 2006 intends to (1) improve long run fiscal sustainability by reducing the growth in public old-age expenditures, (2) strengthen labour supply incentives, and (3) maintain the main redistributive features of the present system. We assess to what extent the reform...

Large petroleum revenues make Norway an enviable fiscal loner. The fiscal policy rule adopted from 2001 transforms petroleum wealth into foreign assets, and only the real return on the financial fund should be spent annually. Despite this ambitious saving of the petroleum wealth, we find it...

Ageing combined with generous welfare state schemes makes the present fiscal policy in Norway unsustainable, despite large government petroleum revenues. We estimate to what extent two suggested reforms of the public pension system improve fiscal sustainability and stimulate employment, two main...

Assessments of fiscal sustainability (FS) problems should be based on present values of government revenues and expenditures over an infinite horizon. The paper shows that realistic assumptions imply that the growth rate of government expenditure components may exceed both the steady state...

Supporters of public disclosure of personal tax information point to its deterrent effect on tax evasion, but this effect has not been empirically explored. Although Norway has a long tradition of public disclosure of tax filings, it took a new direction in 2001 when anyone with access to the...

In order to analyse the consequences of uncertainty for prices and efficiency in a hydropower system, we apply a two-period model with uncertainty in water inflow. We study three different market structures, perfect competition, monopoly and oligopoly and stress the importance of the shape of...

Economists, in particular Bresnahan and Trajtenberg (1995), have recently drawn attention to the importance of generic or general purpose technologies (GPTs) and their significance for economic growth. An interesting part of this research identifies coordination problems in the introduction of...

The formation of peer groups with social norms for private contributions to a public good is analyzed in an n-player two stage game. First people choose a peer group, then they choose whether to contribute. The first choice is made through a learning process represented by evolutionary dynamics,...
