The Impact of Sanitary and Phytosanitary Measures on Market Entry and Trade Flows

In an attempt to disentangle the impact of sanitary and phytosanitary (SPS) measures on trade patterns, we use the database on specific trade concerns on SPS measures of the WTO. Estimating various gravity model specifications at the HS4 disaggregated level of trade, we find that aggregated SPS measures constitute obstacles to agricultural and food trade consistently to all exporters. But conditional on market entry, trade flows are positively affected by SPS measures. In addition, we find that SPS measures related to conformity assessment hamper market entry, while SPS measures related to product characteristics increase bilateral trade flows conditional on meeting the standard.

The reverse Napoleon effect: The brand appreciation of looking up by tall people

Integrating the embodied cognition framework with research on the self, this study shows that head canting (the vertical tilt of the head to look up vs. down) interacts with a viewer's physical height to influence perceived brand power and behavioral intentions. Three studies use a variety of brand cues in both laboratory and field contexts to test the effect of head canting on brand power evaluations, the role of a person's physical height as a moderator and boundary condition, and the mediating role of consumer–brand identification. Study 1, an experiment, showed that tall, but not short individuals, evaluate a brand as more powerful when looking up (rather than down) at a brand story from a standing position, with differences in brand power impacting brand attitudes and choice. Study 2 replicates these findings with 30 brands, consumers positioned in a seated position, and brand logos. Both studies rule out the construal level as a process mediator. Study 3 further examines the process and demonstrates that the interaction of head canting with a person's height impacts consumer–brand identification, which mediates brand evaluations. These findings add a brand management and physical-self perspective to previous embodiment research by specifically examining the effects of sensorimotor experiences.     

Schwaches Produktivitätswachstum — zyklisches oder strukturelles Phänomen?

Labour productivity growth in Germany and in the OECD countries has decelerated significantly in recent years. This observation is astonishing, given the fact that modern digital services can now be found throughout the economy. It may be a statistical artefact, but if it is a realistic observation, it should be investigated. The authors describe many reasons for this development. For example, the services sector, with its traditionally low productivity, makes up an increasingly large part of the economy. Moreover, the cost intensity of innovations is growing, and there are not enough innovative investments. What should be done? Reforms are suggested which aim at exploiting unused potential and create suitable conditions for facilitating sustainable productivity increases. Important policy areas include digitisation, energy transition and demographic change. But reforms must also be thought of as investments into the capacity of employees to work productively.     

More than Just an Opinion: The Effect of Verbal Self‐Expression on Consumer Choice

In an ever‐widening range of occasions, consumers have the opportunity to comment and express their opinions on brands and products. However, little is known about how voicing opinions about the choice options before actually choosing might affect consumer choice, and specifically liking of choice. This paper proposes that pre‐choice opinion expression undermines the effect of post‐choice bolstering, because opinion sufficiently satisfies self‐expressive needs and therefore supersedes the use of subsequent choice as a self‐expressive resource. This proposition is based on the assumption that opinion can psychologically substitute for choice, because the two represent alternative routes to self‐expression. Two experiments provide empirical support for this hypothesis. Study 1 showed that after articulating their opinions about the choice options, participants were less likely to idealize their choices, and this effect was mediated by a change in the construal of choice as self‐expression. Study 2 further showed that this effect is moderated by public versus private occasions of opinion voicing and by individual differences in the value of expression. Together, findings support that opinion is enough to express the self, and if such an opportunity is made available prior to choosing, consumers’ liking of their choices is weakened.
