Real-time versus Day-ahead Market Power in a Hydro-based Electricity Market

Mauritzen, Johannes; Tangerås, Thomas - Institutet för Näringslivsforskning (IFN) - 2014

We analyse in a theoretical framework the link between real-time and day-ahead market performance in a hydro-based and imperfectly competitive wholesale electricity market. Theoretical predictions of the model are tested on data from the Nordic power exchange, Nord Pool Spot (NPS).We reject the...

The Silver Lining of Price Spikes: How Electricity Price Spikes Can Help Overcome the Energy Efficiency Gap

Mauritzen, Johannes - Institutet för Näringslivsforskning (IFN) - 2014

Studies have shown that many consumers and businesses fail to invest in energy efficiency improvements despite … seemingly ample financial incentives to do so – the so called energy efficiency gap or paradox. Attempts to explain this gap … significant positive effect on searching for information on energy efficiency goods. Because consumers pay for electricity based …

Market Power in the Nordic Wholesale Electricity Market: A Survey of the Empirical Evidence

Fridolfsson, Sven-Olof; Tangerås, Thomas - Institutet för Näringslivsforskning (IFN) - 2008

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...

Car Age, Taxation, Scrappage Premiums and the ELV Directive

Sandström, F. Mikael - Institutet för Näringslivsforskning (IFN) - 2003

A chain of replacement model is used to examine the effects of automobile taxes and of a scrappage premium on the life length of cars, and on the size of the car fleet. The predictions of the model are tested on data on the scrappage of cars in Sweden 1989-2002. The theoretical model predicts...

Now or Later? Trading Wind Power Closer to Real-time and How Poorly Designed Subsidies Lead to Higher Balancing Costs

Mauritzen, Johannes - Institutet för Näringslivsforskning (IFN) - 2013

An important challenge facing many deregulated electricity markets is dealing with the increasing penetration of intermittent generation. Simulation studies have pointed to the advantages of trading closer to real-time with large amounts of intermittent generation. Using Danish data, I show...

A Reexamination of Renewable Electricity Policy in Sweden

Fridolfsson, Sven-Olof; Tangerås, Thomas - Institutet för Näringslivsforskning (IFN) - 2012

Green certificates are the main instrument for promoting renewable electricity (RES-E) in Sweden. But certificates cover only a limited share of total RES-E production. Under partial coverage, crowding out may arise whereby costly new RES-E replaces inexpensive old RES-E. Granting certificates...

Renewable Electricity Policy and Market Integration

Tangerås, Thomas - Institutet för Näringslivsforskning (IFN) - 2013

I analyze renewable electricity policy in a multinational electricity market with transmission investment. If national policy makers choose support schemes to maximize domestic welfare, then a trade policy motive arises operating independently of any direct benefit of renewable electricity. The...

Nuclear Capacity Auctions

Fridolfsson, Sven-Olof; Tangerås, Thomas - Institutet för Näringslivsforskning (IFN) - 2011

We propose nuclear capacity auctions as a means to improve the incentives for investing in nuclear power. A properly designed auction would (i) allocate the license to the most efficient bidder; (ii) sell the license if and only if new nuclear power was socially optimal. In particular, capacity...

Oil Prices and Real Exchange Rate Movements in Oil-Exporting Countries: The Role of Institutions

Rickne, Johanna - Institutet för Näringslivsforskning (IFN) - 2009

Political and legal institutions affect the extent to which the real exchange rates of oil-exporting countries co-move with the oil price. In a simple theoretical model, strong institutions insulate real exchange rates from oil price volatility by generating a smooth pattern of fiscal spending...

Firm Productivity and Carbon Leakage: A Study of Swedish Manufacturing Firms

Ferguson, Shon; Sanctuary, Mark - Institutet för Näringslivsforskning (IFN) - 2014

This paper examines the intensive and extensive margins of carbon leakage. The analysis uses an increase in the Swedish electricity price to identify the impact on imports at the firm and product level. Our model of heterogenous firms predicts that higher domestic electricity prices lead firms...
