House price seasonality, market activity, and the December discount
Show summary
In Norway, house prices tend to drop in December. This regularity is persistent across regions and over time. I exploit a transaction data set with high temporal granularity to document and estimate the size of the December discount. I control for a composition effect using a hedonic model and I control for unobserved heterogeneity by using repeat sales and involving ask prices and appraisal values. By segmenting into submarkets, I search for determinants of price seasonality. The evidence suggests that the December effect is linked to time-on-market for each unit and transaction volumes within each submarkets.

IV estimation of spatial dynamic panels with interactive effects: large sample theory and an application on bank attitude towards risk
Show summary
This paper develops a new instrumental variables estimator for spatial, dynamic
panels with interactive effects under large N and T asymptotics. For this class of models, most
approaches available in the literature are based on quasi-maximum likelihood estimation. The
approach put forward here is appealing from both a theoretical and a practical point of view
for a number of reasons. First, it is linear in the parameters of interest and computationally
inexpensive. Second, the IV estimator is free from asymptotic bias. Third, the approach can
accommodate endogenous regressors as long as external instruments are available. The IV
estimator is consistent and asymptotically normal as N, T → ∞ , such that N/T → c , where
0 < c < ∞ . We study the determinants of risk attitude of banking institutions. The results
show that the capital regulation introduced by the Dodd–Frank Act has succeeded in influencing
banks’ behaviour.

COVID-19 among guestworkers in Norway
Show summary
Guestworkers in Norway is a group we have little knowledge about, even though this group makes up nearly 4% of the Norwegian workforce in high seasons during a normal year. During the COVID-19 pandemic, migrant guestworkers in Norway were the subject of strict infection prevention measures, but there is little knowledge about actual infections in this group compared to residents. In this analysis, we study whether infection rates were higher among guestworkers compared to a relevant comparison group in the general population. A guestworker is a non-resident migrant worker with a temporary id-number (d number) and active employment. Our study gives valuable information on whether additional precautionary measures for this group would have been justified. In this paper we use employment data from the State Register of Employers and Employees (Aa-registeret) from April 1st, 2020 to October 1st, 2021, together with results from PCR tests. We compare the probability of infection among guestworkers in Norway with a group of employees who are permanent residents, controlling for gender, age, occupation and local infection rate. We find a lower confirmed incidence of COVID-19 among guestworkers, and no difference in positivity rate.

The structure of Norwegian seafood trade
Show summary
While seafood is a highly traded commodity, lack of data has largely prevented examination of the firms and industries that are conducting the actual transactions. In this paper we use highly disaggregated data to provide an overview of the seafood exports from Norway, the world’s 2nd largest seafood exporting country, and a country where fisheries as well as aquaculture are important industries. The industry has a global reach with Norwegian seafood reaching 172 different countries in the period 2016–2020. While there are as many as 437 different exporting firms, this is relatively few firms compared to the 11,024 different buyers that import Norwegian seafood. There is significant heterogeneity in the export sector from very small firms handling only a few products to very large firms handling a large variety of products. The average firm is quite specialized and serves only 9 markets. However, there are also a handful of large exporters who ship products from all three main sectors in the Norwegian seafood industry to a large number of markets. The 10% largest companies make up 39% of the total export value and provide significant synergies between the aquaculture, pelagic and whitefish sectors.

Static and dynamic inefficiencies in an optimizing model of epidemics
Show summary
Several externalities arise when agents shield optimally to avoid infection during an epidemic. We classify externalities into static and dynamic and compare the decentralized and optimal solutions when agents derive utility from social interaction. For low infection costs agents shield too little; for high costs they shield too much because of a “rat race to shield”: they delay social action until other agents contract the disease and society reaches herd immunity. Other externalities drive more wedges between the private and social outcomes. The expectation of a fully effective vaccine that ends the disease faster changes results, reversing excessive shielding.

Reference points in sequential bargaining: theory and experiment
Show summary
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.

Symbolic stationarization of dynamic equilibrium models
Show summary
Dynamic equilibrium models are specified to track persistent time series. Thus, unit roots are typically introduced as exogenous driving forces and the optimality conditions adjusted to produce a stationary solution. This adjustment step requires tedious algebra and often leads to algebraic mistakes, especially in complicated models. We propose an algorithm employing differentiation rules that simplifies the step of rendering non-stationary models stationary. It is easy to implement and works when trends are stochastic or deterministic, exogenous or endogenously determined. Three examples illustrate the mechanics and the properties of the approach. A comparison with existing methods is provided (97 words).

Dynamic spending and portfolio decisions with a soft social norm
Show summary
We explore the implications of a preference ordering for an investor-consumer with a strong preference for keeping consumption above an exogenous social norm, but who is willing to tolerate occasional dips below it. We do this by splicing two CRRA preference orderings, one with high curvature below the norm and the other with low curvature at or above it. We find this formulation appealing for many endowment funds and sovereign wealth funds, including the Norwegian Government Pension Fund Global, which inspired our research. We derive an analytical solution, which we use to describe key properties of the policy functions for consumption and portfolio allocation. We find that annual spending should not only be significantly lower than the expected financial return, but mostly also procyclical. In particular, financial losses should, as a rule, be followed by larger than proportional spending cuts, except when some smoothing is needed to keep spending from falling too far below the social norm. Yet, at very low wealth levels, spending should be kept particularly low in order to build sufficient wealth to raise consumption above the social norm. Financial risk taking should also be modest and procyclical, so that the investor sometimes may want to “buy at the top” and “sell at the bottom.” Many of these features are shared by habit-formation models and other models with some lower bound for consumption. However, our specification is more flexible and thus more easily adaptable to actual fund management. The nonlinearity of the policy functions may present challenges regarding delegation to professional managers. However, simpler rules of thumb with constant or slowly moving equity share and consumption-wealth ratio can reach almost the same expected discounted utility. Nevertheless, the constant levels will then look very different from the implications of expected CRRA utility or Epstein–Zin preferences in that consumption is much lower.

Volterra Equations Driven by Rough Signals 3: Probabilistic Construction of the Volterra Rough Path for Fractional Brownian Motions
Show summary
Based on the recent development of the framework of Volterra rough paths (Harang
and Tindel in Stoch Process Appl 142:34–78, 2021), we consider here the probabilistic
construction of the Volterra rough path associated to the fractional Brownian motion
with H > 1
2 and for the standard Brownian motion. The Volterra kernel k(t,s) is
allowed to be singular, and behaving similar to |t − s|
−γ for some γ ≥ 0. The
construction is done in both the Stratonovich and Itô senses. It is based on a modified
Garsia–Rodemich–Romsey lemma which is of interest in its own right, as well as
tools from Malliavin calculus. A discussion of challenges and potential extensions is
provided.

Changing Supply Elasticities and Regional Housing Booms
Show summary
Developments in U.S. house prices over the past decade mirror those of the 1996–2006 boom. Construction activity has, however, been weak. Using data for 254 U.S. metropolitan areas, we show that housing supply elasticities have fallen markedly in recent years. We find that housing supply elasticities have declined more in areas in which land-use regulation has tightened the most, and in areas that experienced the sharpest housing busts. Consistent with the declining housing supply elasticities, we find that monetary policy shocks have had a stronger effect on house prices during the past decade than during the previous boom. At the same time, building permits respond less.

Public Employees as Elected Politicians: Assessing Direct and Indirect Substantive Effects of Passive Representation
Show summary
In many countries, public sector employees are eligible to hold political offices during their employment as civil servants. This often triggers conflict-of-interest concerns that elected public employees might sway policies to their professional benefit. In this article, we build on representation scholarship in political science and public administration to assess such substantive effects of public employees’ political representation using detailed Norwegian administrative register and survey data (2003–19). Our main results indicate that public employees differ little from other members within their party in terms of ideology and policy preferences. They do, however, appear to move their party slightly toward the left of the political spectrum, consistent with preference spillover effects induced by heightened public sector representation. Finally, using an instrumental variable approach exploiting close elections, we find that political representation of public employees is associated with at best modest public spending, employment, and wage effects at the local level.

The price of cost-effectiveness thresholds under therapeutic competition in pharmaceutical markets
Show summary
Health systems around world are increasingly adopting cost-effectiveness (CE) analysis to inform decisions about access and reimbursement. We study how CE thresholds imposed by a health plan for granting reimbursement affect drug producers’ pricing incentives and patients’ access to new drugs. Analysing a sequential pricing game between an incumbent drug producer and a potential entrant with a new drug, we show that CE thresholds may have adverse effects for payers and patients. A stricter CE threshold may induce the incumbent to switch pricing strategy from entry accommodation to entry deterrence, limiting patients’ access to the new drug. Otherwise, irrespective of whether entry is deterred or accommodated, a stricter CE threshold is never pro-competitive and may in fact facilitate a collusive outcome with higher prices of both drugs. Compared to a laissez-faire policy, the use of CE thresholds when an incumbent monopolist is challenged by therapeutic substitutes can only increase the surplus of a health plan if it leads to entry deterrence. In this case the price reduction by the incumbent necessary to deter entry outweighs the health loss to patients who do not get access to the new drug.

The competing influence of psychological job control on family-to-work conflict
Journal of Occupational and Organizational Psychology, 96(2), p. 351-377.
Doi:
10.1111/joop.12426
Show summary
Psychological job control has typically been negatively related to work-to-family and family-to-work conflict. Based on the job demand-resource model and boundary theory, we argue that psychological job control may indirectly be positively related to family-to-work conflict by both increasing supplemental work, that is, the rate of engagement in work outside of formal working hours without receiving compensation aided by mobile technology, and work-to-family conflict. We hypothesize that this proposed positive indirect relationship will be lower among employees who perceive a high segmentation norm at their workplace. Based on a two-wave study of 4518 employees, we obtained support for a serial moderated mediation model that suggests a dual effect of psychological job control on family-to-work conflict, such that psychological job control was positively associated with family-to-work conflict through supplemental work and work-to-family conflict at low levels of segmentation norms. By examining the dual effects of psychological job control, this study aims to further understand the mechanisms involved in determining whether and when psychological job control, together with supplemental work, encourages employees to uphold or cross boundaries between work and nonwork domains. Our findings imply that psychological job control can both be a resource and a demand depending on the levels of segmentation norms.

The impact of terrorism on civil servants: Longitudinal evidence from the July 22, 2011 attack in Norway
Show summary
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.

Fancy Seeing You Here…Again: Uncovering Individual-Level Panel Data in Repeated Cross-Sectional Surveys
Show summary
Many theories in Public Administration and Public Management explicitly relate to changes over time in the attitudes, values, perceptions, and/or motivations of public-sector employees. Examining such theories using (repeated) cross-sectional datasets may lead to biased inferences and an inability to expose credible causal relationships. As developing individual-level panel datasets is costly and time-consuming, this article presents a method to make better use of existing surveys fielded repeatedly among the same respondent pool without individual identifiers. Specifically, it sets out an approach to create a system of unique identifiers using information about respondents' background characteristics available within the original data. The result is a panel dataset that allows tracking (a subset of) individual respondents across time. The article discusses issues of feasibility, credibility as well as ethical considerations. The methodology has further practical value by highlighting data characteristics that can help minimize identifiability of respondents while creating public-release datasets.

The politics of distributing blame and credit: Evidence from a survey experiment with Norwegian local politicians
Show summary
How do politicians attribute responsibility for good and poor policy outcomes across multiple stakeholders in a policy field where they themselves can affect service provision? Such ‘diffusion’ decisions are crucial to understand the political calculations underlying the allocation of blame and credit by office-holders. We study this issue using a between-subjects survey experiment fielded among local politicians in Norway (N = 1073). We find that local politicians attribute responsibility for outcomes in primary education predominantly to school personnel (regardless of whether performance is good or bad) and do not engage in local party-political blame games. However, we show that local politicians are keen to attribute responsibility for poor outcomes to higher levels of government, especially when these are unaligned with the party of the respondent. These findings suggest that vertical partisan blame-shifting prevails over horizontal partisan blame games in settings with a political consensus culture.

Information, perceptions, and electoral behaviour of young voters: A randomised controlled experiment
Show summary
The way people absorb and process politically relevant information is central to their subsequent political behaviour (in terms of turnout and vote choice). Nonetheless, little is known about how young voters – who might be more impressionable than more experienced voters – respond to the provision of such information. In this article, we design a between-subject randomised controlled trial that exposes a sample of university students to positive, neutral or negative information about central government performance before the 2017 Portuguese local elections. We find that young voters update their perceptions more when exposed to negative news. This negativity bias is stronger for first-time voters. We also find that negative information significantly affects turnout of initially undecided young voters. Our results imply that sensitivity to information is heterogeneous and that some young voters may be prone to manipulation through the provision of negative news.

Improved tests for Granger noncausality in panel data
Show summary
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.

New results on asymptotic properties of likelihood estimators with persistent data for small and large T
Show summary
This paper revisits the panel autoregressive model, with a primary emphasis on the unit-root case. We study a class of misspecified Random effects Maximum Likelihood (mRML) estimators when T is either fixed or large, and N tends to infinity. We show that in the unit-root case, for any fixed value of T, the log-likelihood function of the mRML estimator has a single mode at unity as
. Furthermore, the Hessian matrix of the corresponding log-likelihood function is non-singular, unless the scaled variance of the initial condition is exactly zero. As a result, mRML is consistent and asymptotically normally distributed as N tends to infinity. In the large-T setup, it is shown that mRML is asymptotically equivalent to the bias-corrected FE estimator of Hahn and Kuersteiner (Econometrica 70(4):1639–1657, 2002). Moreover, under certain conditions, its Hessian matrix remains non-singular.

Child Penalties in Politics
Show summary
Women tend to experience a substantial decline in their labour income after their first child is born, while men do not. Do such ‘child penalties’ also exist in the political arena? Using comprehensive administrative data from Norway, we find that women are less likely than men to secure elected office after their first child is born. The effects manifest already from the nomination stage, where mothers receive less favourable rankings on party lists relative to comparable fathers. This paper broadens our understanding of a fundamental social issue in political representation and demonstrates how motherhood affects even positively selected women.

Judicial subversion: The effects of political power on court outcomes
Show summary
Are politicians in power treated more leniently in court? We show that Brazilian mayoral candidates charged with misconduct are 65 percent less likely to be convicted if they narrowly win the election. Politicians play no direct role in the judges’ careers, suggesting that formal independence does not completely insulate the judiciary from political influence. The effect is driven by districts with few judges and by judges with higher career instability.

On Dihedral Angle Sums of Prisms and Hexahedra
Show summary
Various angle characteristics are used (e.g. in finite element methods or computer graphics) when evaluating the quality of computational meshes which may consist, in the three-dimensional case, of tetrahedra, prisms, hexahedra and pyramids. Thus, it is of interest to derive (preferably tight) bounds for dihedral angle sums, i.e. sums of angles between faces, of such mesh elements. For tetrahedra this task was solved by Gaddum in 1952. For pyramids, this was resolved by Korotov, Lund and Vatne in 2022. In this paper, we compute tight bounds for the remaining two cases, hexahedra and prisms.

SEQUENTIAL PRICE SETTING: THEORY AND EVIDENCE FROM A LAB EXPERIMENT
Show summary
In the Varian (1980; American Economic Review 70(4) (1980), 651–59) model of price competition, a change from simultaneous to sequential price setting dramatically changes equilibrium strategies, and in the unique symmetric, equilibrium prices are pushed up to the monopoly price. There also exists an asymmetric equilibrium with lower average prices. Our main contribution is to test these predictions in the laboratory. Our data strongly support the qualitative model predictions. However, a fraction of players set low prices in accordance with the asymmetric equilibrium, which is puzzling. We show that the puzzle to a large extent can be resolved by introducing competitive preferences in the model.
