In the paper attempts are made to integrate two parts of Trygve Haavelmo’s work: investment theory and dynamic econometric models of interrelated markets. Specifically, the duality in the representation of the capital service price and the capital quantity in relation to the investment price and quantity are brought to the forefront and confronted with elements from simultaneous equation modeling of vector autoregressive systems containing exogenous variables (VARX), using linear four-equation models. The role of the interest rate and the modeling of the expectation element in the capital service price and the capital’s retirement pattern, and their joint effect on the model’s investment quantity and price dynamics are discussed. Stability conditions are illustrated by examples. Extensions relaxing geometric decay and ways of accounting for forward-looking behavior, including rational expectations, are outlined. Some remarks on the theory-data confrontation of this kind of model are given.

Abstract Optimal perturbations are constructed for a two-layer β-plane extension of the Eady model. The surface and interior dynamics is interpreted using the concept of potential vorticity building blocks (PVBs), which are zonally wavelike, vertically confined sheets of quasigeostrophic potential vorticity. The results are compared with the Charney model and with the two-layer Eady model without β. The authors focus particularly on the role of the different growth mechanisms in the optimal perturbation evolution. The optimal perturbations are constructed allowing only one PVB, three PVBs, and finally a discrete equivalent of a continuum of PVBs to be present initially. On the f plane only the PVB at the surface and at the tropopause can be amplified. In the presence of β, however, PVBs influence each other’s growth and propagation at all levels. Compared to the two-layer f-plane model, the inclusion of β slightly reduces the surface growth and propagation speed of all optimal perturbations. Responsible for the reduction are the interior PVBs, which are excited by the initial PVB after initialization. Their joint effect is almost as strong as the effect from the excited tropopause PVB, which is also negative at the surface. If the optimal perturbation is composed of more than one PVB, the Orr mechanism dominates the initial amplification in the entire troposphere. At low levels, the interaction between the surface PVB and the interior tropospheric PVBs (in particular those near the critical level) takes over after about half a day, whereas the interaction between the tropopause PVB and the interior PVBs is responsible for the main amplification in the upper troposphere. In all cases in which more than one PVB is used, the growing normal mode configuration is not reached at optimization time.

The contemporary genomic diversity of viruses is a result of the continuous and dynamic interaction of past ecological and evolutionary processes. Thus, genome sequences of viruses can be a valuable source of information about these processes. In this review, we first describe the relevant processes shaping viral genomic variation, with a focus on the role of host–virus coevolution and its potential to give rise to eco-evolutionary feedback loops. We further give a brief overview of available methodology designed to extract information about these processes from genomic data. Short generation times and small genomes make viruses ideal model systems to study the joint effect of complex coevolutionary and eco-evolutionary interactions on genetic evolution. This complexity, together with the diverse array of lifetime and reproductive strategies in viruses ask for extensions of existing inference methods, for example by integrating multiple information sources. Such integration can broaden the applicability of genetic inference methods and thus further improve our understanding of the role viruses play in biological communities.

AbstractHow important is the enforcement of political rights in new democracies? The authors use the enfranchisement of the emancipated slaves following the American Civil War to study this question. Critical to their strategy, black suffrage was externally enforced by the United States Army in ten Southern states during Reconstruction. The authors employ a triple-difference model to estimate the joint effect of enfranchisement and its enforcement on taxation. They find that counties with greater black-population shares that were occupied by the military levied higher taxes compared to similar nonoccupied counties. These counties later experienced a comparatively greater decline in taxation after the troops were withdrawn. The authors also demonstrate that in occupied counties, black politicians were more likely to be elected and political murders by white supremacist groups occurred less frequently. The findings provide evidence on the key role of federal troops in limiting elite capture by force during this period.

Drawing upon ideas stemming from social disorganisation theory, this study explores how structural and social aspects of the school context affect youth substance-use behaviours in terms of smoking, alcohol and/or drug use. A key focus is to investigate the joint effect of school collective efficacy and schools’ substance-use norms on students’ substance use. Analyses are based on combined information from two independent data collections conducted in 2014 among ninth grade students ( n = 5122) and teachers ( n = 1105) in 81 senior-level schools in Stockholm. Results from multilevel analyses confirm previous research by suggesting that the proneness to engage in substance use varies depending on the socioeconomic profile of the school. Youth in socioeconomically advantaged schools were more prone to engage in substance use than youth in disadvantaged school settings. Furthermore, collective incentives for exerting social control against substance use seem to be weaker in schools where conventional values towards substance use (anti-substance-use norms) are suppressed.

The Impact

Prior research demonstrates that status demotion in the loyalty reward program heightens negative emotions, particularly when demotion is due to changes in company policies. In this research, we argue that such negative emotions are likely to spillover to evaluations of post-demotion promotions. We further argue that such spillover effects should be attenuated among individuals high in need for status. Study 1 examines the joint effect of the cause of demotion and customers’ need for status on loyalty. In study 2, we investigate the impact of exclusivity cues in post-demotion promotions and show that exclusive promotions diminish the negative impact of policy-based demotions on post-promotion loyalty among individuals high (vs. low) in need for status. Travel and tourism companies might want to consider using geographical location as a proxy for need for status or priming status-seeking via exclusive promotions (“elevate your travel experience”) to alleviate demoted customers’ negative emotions.

Moderating Role

There are two typical forms of trust in organisational settings—institution-based trust and interpersonal trust. The role of interpersonal trust in promoting interdepartmental knowledge sharing has been investigated. The effect of institution-based trust, especially the joint effect of institution-based and interpersonal trust, on interdepartmental knowledge sharing has not been adequately described. This article builds a conceptual model to describe the independent and joint effects of these two forms of trust on the satisfaction and success of interdepartmental knowledge sharing. The moderating role of knowledge tacitness is also described in this model, which is tested on 294 collaborative task scenarios between departments within Chinese IT firms. The empirical results essentially support the proposed model and contribute to organisational trust and interdepartmental knowledge-sharing discussions by clarifying the substantial roles of these two forms of trust in the context of interdepartmental collaboration and knowledge sharing.
