The literature on taxation of rents from nonrenewable resources uses different theoretical assumptions and methods and a variety of empirical observations to arrive at widely diverging conclusions. Many studies use models and methods which disregard uncertainty, investigating distortionary...

Under international tax competition, corporate income tax rates are predicted to decrease, and the tax burden will shift onto immobile factors. This case study considers tax changes that illustrate the predictions for Norway 2012-2018. Petroleum rent was taxed at high rates in 2012, and while...

From a CAPM-type model the cost of equity is derived for a firm operating under various foreign tax systems. The firm’s shares are traded in a market which is unaffected by these systems. The cost of capital depends on the foreign tax system, even for fully equity financed projects. This is...

We discuss the prevalence of pooling equilibria in a two-period model of an insurance market with asymmetric information. We solve the model numerically. In addition to reporting cases where a pooling equilibrium exists, we pay attention to why, in the case of non-existence of a pooling...

Non-neutral taxation, and in particular imperfect loss offset, is shown to have a strong effect not only on investment decisions, but also on required expected after-tax rates of return to equity. Systematic risk is valued according to the CAPM, while non-linear taxes are valued by option...

Lund (2002a) showed in a CAPM-type model how tax depreciation schedules affect required expected returns after taxes. Even without leverage higher tax rates implied lower betas when tax deductions were risk free. Here they are risky, and marginal investment is taxed together with inframarginal...

Even for fully equity-financed firms there may be substantial effects of taxation on the after-tax cost of capital. Among the few studies of these effects, even fewer identify all effects correctly. When marginal investment is taxed together with inframarginal, marginal beta differs from average...

A framework for forecasting new COVID-19 cases jointly with hospital admissions and hospital beds with COVID-19 cases is presented. This project, dubbed CovidMod, produced 21-days ahead forecasts each working day from March 2021 to April 2022, and forecast errors that were used to assess...

We estimate the quantitative importance of labour market institutions for equilibrium unemployment in OECD. The empirical equation for unemployment is based on the solution of a dynamic macroeconomic model where wages and prices are jointly determined with unemployment. Compared to existing...

Macroeconomic theories take polar views on the importance of choice versus chance. At the micro level, it seems realistic to assume that both dimensions play a role for individual employment outcomes, although it might be difficult to separate these two effects. Nevertheless the choice and...
