    Camawa. Can, may and want. These are the constituents of the home office frequency decision. Not every job can be done from home nor is it a matter of all or nothing. Every job profile can be positioned on a continuum reflecting its home office feasibility. Further, those who can, might not may: Firms call back employees to the office or set constraints such as a home office budget. Last but not least 'cama' does not mean anything without 'wa' - the preference dimension. This work tries to account for all three dimensions simultaneously by means of a structural equation model (SEM). We find that the may dimension is of most substance and an employee's perception of her employer's point of view plays a crucial role in it. Meanwhile, preferences are governed by several suitability considerations. Personal suitability, residential suitability and the suitability of the home office workstation play into the decision, perceived personal suitability being the most important of the three.
  • Home office frequency and mobility tool ownership choices
    Item type: Conference Poster
    Heimgartner, Daniel; Sallard, Aurore; Balać, Miloš; et al. (2023)
    Home office is the lasting legacy of the pandemic. This study explores the preferences for different work from home (WFH) arrangements and scrutinizes their implications for mobility tool ownership (MTO). Together with alternative daily activity chains the expected shift in transport demand can be simulated under various hybrid work scenarios thereby supporting strategic decision making.
  • Preferred strategies to reduce CO2-emissions by 30
    Item type: Conference Paper
    Heimgartner, Daniel; Lichtin, Florian Maurus; Axhausen, Kay W. (2024)
    While cost of climate policies and their distributional consequences have become increasingly relevant, very little is currently known about how people across societal sub-groups evaluate and trade-off necessary behavioural changes and financial costs when faced with decisions about how to reduce individual carbon emissions. To understand such preferred pathways, a priority evaluator experiment was fielded. 3‘456 participants were tasked to reduce their initial carbon emission levels by 30% by choosing their preferred strategy mix and how intensely they want to pursue any chosen strategy. We use a Multiple Discrete-Continuous Extreme Value Model (MDCEV) to model both dimensions simultaneously. We find that while strategies that imply behavioral change are generally accepted, they usually only contribute little to overall savings. Meanwhile, outsourcing a considerable chunk of reductions via certificates is a prominent choice. In particular, high-income households tend to reduce emissions via investments, while lower-income households may have to bear disproportionally more of the behavioral cost in order to reach the reduction target. People further to the right on the political scale reach the target less frequently and prefer measures that benefit the housing unit (better insulation of the facade and roof), or install solar panels. This might be important since right-leaning individuals are generally more critical of climate change and the need to take personal action. Incentivizing these individuals to invest in reduction strategies might therefore be pivotal.
  • Understanding modal splits before, during, and after the pandemic
    Item type: Working Paper

    Arbeitsberichte Verkehrs- und Raumplanung
    The adjustments of mobility patterns during early stages of the pandemic are well understood. However, various effects are intertwined in these observations and therefore the findings’ robustness remains questionable. The MOBIS-Covid data set provides a unique opportunity to put these initial findings in perspective as a large panel has been tracked from before the crisis up until today. Switzerland lifted all its measures counteracting the spread in mid February, reaching a potential new equilibrium in the months that followed. A comprehensive set of descriptive indicators has been constructed in order to disentangle the narrative of the crisis from the perspective of transport demand. Special emphasis has been given to the question of how new hybrid working arrangements drive modal splits (as measured by mode distance shares). The descriptive findings are strengthened by a mixed multiple discrete- continuous extreme value model (MMDCEV). We find a strong shift in modal splits from car and train, to more regional, slow-moving modes. This effect is very likely to persist with new working arrangements established. Car could in fact loose the most considerable mode share due to home office. We estimate an upper bound indicating that the car mode share drops from 62% to 52%). This contrasts previous literature: Once we control for working from home and commuting trips, car in fact looses importance. Train (being the other main commute mode) looses mode share in similar relative dimensions as car does.

    While the home office frequency choice is well researched, applicable work arrangement attributes are usually not known and therefore omitted. The goal of our work is to elicit the attractiveness of different hybrid work policies as well as their implications for home office frequencies. We hypothesize that in the absence of any incentive schemes or constraints, employees would choose their stated free choice frequency and any deviation from it has to be attributed to the work arrangemenet. Multinomial logit (work arrangement choice) and ordinal logistic regression (frequency choice) models are employed, leveraging stated preference data uniquely collected for this purpose. We find that salary adjustments provide the biggest lever both in terms of attractiveness of the arrangement and its elasticity effect on telework supplied. While its practicality remains questionable it puts the other proposed attributes into proportion which all have considerable smaller effects (while significant). The only other substantial policy is whether or not work from anywhere is allowed. The resulting elasticity effects make it unlikely that large variations in telework frequencies can be attributed to work policies. This strengthens the big body of empirical work which abstracts from these factors.
