Sweden has experienced a sequence of tax and benefit reforms during the last decade. The purpose of this paper is to evaluate these extensive reforms from the points of view of labour supply, welfare and inequality. As a basis of the analysis, we use the household labour supply model, which is...

This paper concerns green accounting in a global economy, which is characterized by transboundary environmental problems. The world is divided into two separate regions, and the regions differ substantially with respect to income per capita, emissions of greenhouse gases per capita, population...

This paper analyses how market shares for brand name drugs are affected by generic competition. The analysis is based on micro data for twelve original drugs, wich are all subject to generic competition. For five of these drugs, we find that the price of the original relative to the average...

This paper analyzes the welfare consequences of coordinated tax reforms in an economy where a transboundary environmental externality and an international wage bargaining externality are operative at the same time. We assume that the wage in each country is decided upon in a bargain between...

There is a rich literature analyzing the problems that will arise as the share of elderly and retired in the population increases in the near future. However, the locational decisions among the elderly as well as their implications in terms of taxes/transfers and of allocation of...

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The government is assumed to act in accordance with a utilitarian objective function. The main purpose of the paper is to study the determinants of tax progression and,...

This paper concerns redistribution and optimal taxation in an OLG model with two employed ability-types. We assume that the wage rates are determined by bargaining between unions and firms, implying that the equilibrium is characterized by unemployment. The tax instruments are nonlinear taxes on...

This paper concerns redistribution and provision of public goods in an economic federation with two levels of government: a local government in each locality and a central government for the economic federation as a whole. We assume that each locality is characterized by two ability-types (high...

This paper concerns optimal income and commodity taxation in a two-type overlapping generations model, where used durable goods are traded in a second-hand market. As second-hand transactions are difficult to observe, we assume that the government is unable to directly control second-hand...

In this paper, we introduce cost benefit rules for projects embedded in a stochastic optimal growth framework. We model uncertainty in terms of Brownian motion and Ito integrals. Taking the mathematical expectation of the project means that the Ito integrals vanish, and we end up with a cost...
