Reassessing EU Comparative Advantage: The Role of Technology

IWH-CompNet Discussion Papers,
Nr. 2,
2024
Abstract
Based on the sufficient statistics approach developed by Huang and Ottaviano (2024), we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data requirements, but still comprehensive in terms of information. The lack of systematic cross-industry correlation between export specialization and technological advantage suggests that standard measures of revealed comparative advantage only imperfectly capture a country’s technological prowess due to the concurrent influences of factor prices, market size, markups, firm selection and market share reallocation.

Abstract
In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty—nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for more reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants.

Inflation Concerns and Green Product Consumption: Evidence from a Nationwide Survey and a Framed Field Experiment

IWH Discussion Papers,
Nr. 10,
2024
Abstract
Promoting green product consumption is one important element in building a sustainable society. Yet green products are usually more costly. In times of high inflation, not only budget constraints but also the fear that prices will continue to rise might dampen green product consumption and, hence, limit the effectiveness of exerted efforts to promote sustainable behaviors. To test this suggestion, we conducted a Germany-wide survey with almost 1,200 respondents, followed by a framed field experiment (N=500) to confirm causality. In the survey, respondents’ stated “green” purchasing behavior is, as to be expected, positively correlated with concerns about climate change. It is also negatively correlated with concerns about future inflation and energy costs, but after controlling for observable characteristics such as income and educational level only the correlation with concerns about future prices remains significant. This result is driven by individuals with below-median environmental attitude. In the framed field experiment, we use the priming method to manipulate the saliency of inflation concerns. Whereas sizably relaxing the budget constraint (i.e., by 50 percent) has no impact on the share of organic products in participants’ baskets, the priming significantly decreases the share of organic products for individuals with below-median environmental attitude, similar to the survey data.

Dekarbonisierung in Europa: Regionalwirtschaftliche Effekte in ausgewählten Kohleregionen und kohlenstoffintensiven Regionen Europa
Katja Heinisch, Oliver Holtemöller, Christoph Schult
Wirtschaft im Wandel,
Nr. 3,
2023
Abstract
Die EU hat mit dem „Fit for 55“-Paket zwei große klimapolitische Ziele festgelegt: die Senkung der Treibhausgasemissionen um 55% bis zum Jahr 2030 und Treibhausgasneutralität ab dem Jahr 2050. Im Rahmen des EU-Horizon-2020-Projekts ENTRANCES werden die gesellschaftlichen Effekte der Dekarbonisierung und besonders des Kohleausstiegs in verschiedenen europäischen Regionen interdisziplinär analysiert und darauf basierend Handlungsempfehlungen für die Politik abgeleitet. Der vorliegende Beitrag stellt erste analytische Ergebnisse vor.

Economic Sentiment: Disentangling Private Information from Public Knowledge
Katja Heinisch, Axel Lindner
IWH Discussion Papers,
Nr. 15,
2021
Abstract
This paper addresses a general problem with the use of surveys as source of information about the state of an economy: Answers to surveys are highly dependent on information that is publicly available, while only additional information that is not already publicly known has the potential to improve a professional forecast. We propose a simple procedure to disentangle the private information of agents from knowledge that is already publicly known for surveys that ask for general as well as for private prospects. Our results reveal the potential of our proposed technique for the usage of European Commissions‘ consumer surveys for economic forecasting for Germany.
