HWWI Research

In der Publikationsreihe „HWWI Research“ werden Reports und Paper veröffentlicht, die die Forschungsergebnisse von HWWI Mitarbeitern sowie von Forschungspartnern präsentieren. Sie sind gedacht und konzipiert für nationale und internationale Fachkreise.

HWWI Research Reports stellen ausführlich Ergebnisse der institutseigenen Forschungsarbeit vor. Sie erscheinen sowohl in gedruckter als auch in elektronischer Form.

HWWI Research Papers sind Forschungsbeiträge, die die Ergebnisse der Forschungsarbeit von internen – und bei Kooperationen – auch von externen Wissenschaftlern präsentieren. Sie erscheinen mehrmals im Monat und sind lediglich online verfügbar.

HWWI Research Reports und Papers erscheinen in deutscher oder englischer Sprache (in Ausnahmefällen stehen sie ebenfalls in beiden Sprachen zur Verfügung).

Cost structure of bio-based plastics: A Monte-Carlo-Analysis for PLA

28.06.2021 | HWWI Research Paper 197, Hamburg | von Claudia Wellenreuther, André Wolf, Nils Zander

This paper conducts a meta-analysis of the estimated costs of producing Polylactic Acid (PLA). Cost contributions of specific inputs and process stages are identified through a production chain perspective. By applying the Monte Carlo technique, uncertainties in current estimates are reflected, both regarding technological input requirements and the development of input...

On the right track? The role of work experience in migrant mothers’ current employment probability

25.06.2021 | HWWI Research Paper 196, Hamburg | von Christina Boll, Andreas Lagemann

This paper investigates the role of work experience in migrant mothers’ current employment in Germany. Unlike previous papers, we focus on actual experience and add the motherhood aspect. To this end, we use data from the German Socio-Economic Panel 2013-2018 including the IAB-SOEP Migration Sample.

The Role of COVID-19 in Spatial Reorganization: Some Evidence from Germany

06.05.2021 | HWWI Research Paper 195, Hamburg | von Andree Ehlert, Jan Wedemeier, Tabea Zahlmann

This paper analyzes the role of regional demographic, socioeconomic and political factors on changes in mobility during the COVID-19 pandemic. It provides new empirical evidence for the regional differentiation of lockdown measures and indicates a possible reorganization of spatial economic and social activities beyond the course of the pandemic. Spatial econometric...

Market dynamics of biodegradable bio-based plastics: projections and linkages to European policies

20.08.2020 | HWWI Research Paper 193, Hamburg | von Niklas Döhler, Claudia Wellenreuther, André Wolf

This paper analyzes the future market perspectives for biodegradable bio-based plastics at the global and the European level. Relevant determinants of demand are identified, categorized and used as a basis for own projections. By implementing a system dynamics approach, the evolution of global production capacities is modelled on an annual basis for the period until...

Combined Transport in Europe: Scenario-based Projections of Emission Saving Potentials

19.05.2020 | HWWI Research Paper 192, Hamburg | von Malte Jahn, Paul Schumacher, Jan Wedemeier, André Wolf

The paper at hand discusses the different typologies of combined transportation in Europe. It shows that an improvement of handling infrastructure for combined transport can positively reduce environmental costs of trading between regions. However, the expected emission reduction effects are relatively small in comparison to the total emissions of the transport sector....
