We examine drivers of cost overruns in Norwegian development projects in the oil and gas sector. The multivariate longitudinal econometric analysis employs a unique and detailed dataset consisting of 80 different projects between 2000 and 2015. Among the significant results, we find that the...

The oil and gas sector plays a crucial role in the Norwegian economy. It accounts for a very large proportion of gross domestic product, government revenues, investment and exports. A sharp fall in oil prices has had a significant impact on the economy and focused great attention on the cost...

Development projects in the oil industry often have cost overruns. Through analysis of data from Norwegian development projects in the petroleum industry, this paper investigates the common effect of business cycle developments on cost overruns. Lack of capacity and expertise in a tight supplier...

Cost overrun is ubiquitous in public procurement. We argue that this can be the result of a constraint optimal award procedure when the procurer cannot commit not to renegotiate. If cost differences are more pronounced for more complex designs, it is optimal to fix a simple design ex ante and to...

We extend the literature on local income tax competition by allowing for inter-jurisdictional spillovers and imperfect rivalry in consumption of a publicly provided good. Comparing decentralized second-best results of a theoretical model with an efficient benchmark, we identify three...

We study the effect of reforms that close loopholes in the enforcement of the dividend-withholding tax (DWT). We focus on a Danish reform enacted in 2016, and compare Denmark to its Nordic neighbors. Our main outcome of interest is the quantity of stocks on loan. Before the reform all Nordic...

We study the role of endogenous healthcare choices by households to extend their expected lifetimes on economic growth and welfare in a decentralized overlapping generations economy with the realistic feature that households' savings are held in annuities. We characterize healthcare spending in...

This paper investigates the distributional and efficiency consequences of an environmental tax reform, when the revenue from the green tax is recycled by varying labor tax rates. We build a general equilibrium model with imperfect heterogeneous labor markets, pollution consumption externalities,...

We show the effects of the bargaining power of labour unions on product innovation under decentralised and centralised wage bargaining. In this context, we show the implications of preference function, which affects the market size. A higher union bargaining power increases innovation if...

We provide a theoretical framework to contribute to the current debate regarding the tendency of pharmaceutical companies to direct their R&D toward marketing products that are "follow-on" drugs of already existing drugs, rather than toward the development of breakthrough drugs. We construct a...
