- We explore the impact of climate change adaptation on the technical efficiency of Ethiopian farmers using panel data collected from 6820 farm plots. We employ Green's (2010) stochastic frontier approach and propensity score matching to address selection bias. Our results reveal that climate change adaptation improves the efficiency of maize, wheat and barley production. We also show that failure to account for selection bias underestimates the average efficiency level. Our findings imply that the expansion of climate change adaptation at larger scales will provide a double benefit by curbing climate-related risks and increasing the efficiency of farmers. Moreover, increasing credit access and introducing mechanisms that allow farmers to get enough water during the main growing season will enhance the efficiency of subsistence farmers.

Information policies and biased cost perceptions : The case of Swedish residential energy consumption

Tidskriftsartikel (refereegranskat)abstract
- Households typically receive utility bills where all electricity use during a fixed period is lumped together. The lack of direct feedback in the form of marginal costs of using specific electric appliances potentially leads to mistakes in households' decision-making because of biased cost perceptions. In this paper, we test the commonly held notion that lack of relevant energy-related knowledge results in cost underestimation of using electric appliances that may lead to over-consumption of energy. Contrary to this notion, our results show that less knowledgeable energy consumers tend to have higher cost perceptions than others. This finding implies that less knowledgeable energy consumers may consume too little of energy. We also find that a substantial share of the sampled households, in particular less knowledgeable energy consumers, are less willing to receive relevant cost-free information about their energy use and costs. This finding suggests that poor energy-related knowledge may not only be a matter of high information search and processing costs, but also a matter of consumers’ limited attention capacity.

The effects of wind power on electricity markets : A case study of the Swedish intraday market
- 2021
-
Ingår i: Energy Economics. - : Elsevier. - 0140-9883 .- 1873-6181. ; 96

Tidskriftsartikel (refereegranskat)abstract
- We investigate the process of electricity price formation in the Swedish intraday market, given a large share of wind power in the Swedish electricity system. According to Karanfil and Li's (2017) approach, if the intraday market is efficient, with large shares of intermittent electricity in the entire electricity system, intraday prices should send signals based on scarcity pricing for balancing power. Based on this theory, we analyze Swedish electricity market data for the period 2015–2018 and find that the Swedish intraday market, despite its small trading volumes, is functioning properly. In particular, our results show that intraday price premia mostly respond to wind power forecast errors and other imbalances resulting from either supply or demand sides of the electricity market, as they should if the intraday market is efficient. The results of wind power forecast errors hold for central and southern Sweden, but not for northern Sweden where the share of wind power production is still very small. However, we find no effect of unplanned nuclear power plant outages on intraday price premia.

Realized dynamic effect of retrofits on energy consumption in Soviet-era multi-apartment buildings
- 2024

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Retrofit programs for old and highly energy-inefficient housing stock from the Soviet era are widely believed to offer a rare win-win opportunity for mitigating climate change and addressing acute energy poverty issues in Eastern European urban neighborhoods. However, despite government subsidies and a push for greater energy efficiency, many people do not undertake retrofits. This raises the question: do these retrofits truly deliver the promised returns? This paper aims to examine the effects of retrofit programs on old Soviet-era multi-apartment buildings' realized dynamic energy savings in Lithuania by analyzing monthly energy bills. Our findings suggest that retrofits are associated with a 50% to 59% reduction in average space heating consumption across various post-retrofit periods. Additionally, retrofits have a short-term effect on electricity savings of 3% to 3.6%. However, our cost-benefit analysis indicates that the energy savings were not sufficiently large to cover the initial investment costs.

Social Comparisons in Real Time : A Field Experiment of Residential Electricity and Water Use
- 2021
-
Ingår i: Scandinavian Journal of Economics. - : John Wiley & Sons. - 0347-0520 .- 1467-9442. ; 123:2, s. 558-592
-
Tidskriftsartikel (refereegranskat)abstract
- In this paper, we carry out a field experiment that contributes to the literature on how social comparisons affect residential energy and water use in two important ways. First, we study a social comparison treatment that is continuous and communicated via pre‐installed in‐home displays, which are salient and updated in real time. Second, we estimate the effects of provision of social comparisons on two distinguished resources – electricity and water – in the same experimental setting. We find that, on average, our social comparison reduces daily residential energy consumption by 6.7 percent but has no effect on overall residential water use.
