  Is capture-based aquaculture viable? The case of Atlantic cod in Norway
  Aquaculture, 572, p. 1-7. Doi: 10.1016/j.aquaculture.2023.739520
  Vis sammendrag

  Capture-based aquaculture (CBA) is an important branch of the aquaculture industry that differs from closed cycle farming in that the stocking material consists of captured wild fish or other aquatic organisms. By skipping the difficult early production stages of fish farming, producers can test whether assumed market advantages such as high quality and consistent supply result in higher prices – and whether these are high enough to incentivize further development of CBA and eventually close the production cycle. CBA-initiatives can also be supported by different policy measures to stimulate the activity. Since these measures involve costs, it is important to know at what level and for how long these measures should be implemented to promote economically sustainable CBA activities. We study CBA of Atlantic cod (Gadus morhua) in Norway and find an average price premium of 26% compared to wild harvested cod, but with large interannual variation. However, declining quantities of cod from CBA following reductions in a quota bonus scheme to stimulate activity, indicates that the price premium is not sufficiently large to incentivize further development of the CBA branch of the Norwegian cod industry.

  Improved tests for Granger noncausality in panel data
  The Stata Journal, 23(1), p. 230-242. Doi: 10.1177/1536867X231162034
  Vis sammendrag

  In this article, we introduce the xtgrangert command, which implements the panel Granger noncausality testing approach developed by Juodis, Karavias, and Sarafidis (2021, Empirical Economics 60: 93–112). This test offers superior size and power performance to existing tests, which stem from the use of a pooled estimator that has a faster NT−−−√ convergence rate. The test has several other useful properties: it can be used in multivariate systems; it has power against both homogeneous and heterogeneous alternatives; and it allows for cross-section dependence and cross-section heteroskedasticity.

  Politicians are commonly believed to gain financially from holding and/or having held office. We argue that there may often also be economic downsides to pursuing a political career, and investigate whether and when politicians can(not) capitalize on their political experience. We thereby study both entry into and exit from political office, and directly compare the returns to politics across government levels and types of politicians. Empirically, we build on detailed information from Norwegian administrative register data over the period 1970-2019 to study individual-level income developments before, during and after a political career at the national and local levels (covering nearly 22,000 individuals and 700,000 person-years). Using an event-study methodology, we show that politicians on average witness a significant income boost during their time in office. In sharp contrast, leaving political office is on average associated with a substantial drop in income, which generally outweighs the income gain from entry into office. These findings suggest that most politicians face a net present value loss from holding office.

  The impact of terrorism on civil servants: Longitudinal evidence from the July 22, 2011 attack in Norway
  Public Administration Review, p. 1-13. Doi: 10.1111/puar.13694
  Vis sammendrag

  Building on a growing literature assessing the societal impact of terrorism, this article analyzes whether and how a terror attack targeting public institutions affects civil servants in their day-to-day work. This is an important question to enhance our understanding of how terrorism can (or cannot) affect the operation of core government functions. Theoretically, the study contributes to a broader account of the political consequences of terrorism by combining insights from social identity and organization theory. Empirically, we exploit a two-wave survey fielded before and after the 2011 terror attack in Norway, which allows us to study the same civil servants (N = 186) before and after this event. While terrorists wish to disrupt public institutions, our findings indicate that a terror attack targeting core government institutions strengthens internal cohesion and increases attention to political signals in work tasks. We discuss implications of these effects for the functioning of democratic government.

  Reference points in sequential bargaining: theory and experiment
  The Scandinavian Journal of Economics, 125?(4?). Doi: 10.1111/sjoe.12552
  Vis sammendrag

  We introduce loss aversion in an infinite-horizon, alternating-offers model. When outside options serve as reference points, the equilibrium of our model follows that of the standard Rubinstein bargaining model, i.e., outside options do not affect the equilibrium unless they are binding. However, when reference points are given by the resources players contribute to the pie, the bargaining outcome changes such that a player's share increases in her contribution. We test our model's predictions in the laboratory. As predicted, only binding outside options impact the division of the pie. Data also show that contributions matter for bargaining outcomes when they are activated as reference points, but not quite as predicted by our theory. Proposers gain a higher share of the pie only when they have contributed a higher share than the opponent has.

  covsim: An R Package for Simulating Non-Normal Data for Structural Equation Models Using Copulas
  Journal of Statistical Software, 102(3), p. 1-45. Doi: 10.18637/jss.v102.i03
  Vis sammendrag

  In factor analysis and structural equation modeling non-normal data simulation is traditionally performed by specifying univariate skewness and kurtosis together with the target covariance matrix. However, this leaves little control over the univariate distributions and the multivariate copula of the simulated vector. In this paper we explain how a more flexible simulation method called vine-to-anything (VITA) may be obtained from copula-based techniques, as implemented in a new R package, covsim. VITA is based on the concept of a regular vine, where bivariate copulas are coupled together into a full multivariate copula. We illustrate how to simulate continuous and ordinal data for covariance modeling, and how to use the new package discnorm to test for underlying normality in ordinal data. An introduction to copula and vine simulation is provided in the appendix.
