Abstract:

Large, generalist, technology firms—so-called “big-tech” firms—powerful in their primary market, routinely enter secondary markets consisting of specialist firms. Naturally, one might expect a specialist firm to be fiercely protective of its data as a way to maintain its market position in the secondary market. Counter to this intuition, we demonstrate that a specialist firm willingly shares its market data with an intruding tech generalist. We do so by developing a model of crossmarket competition in which data collected via consumer usage in each market is a factor of product quality in both markets. We show that a specialist firm shares its data to strategically create co-dependence between the two firms, thereby softening competition and transforming the generalist firm from a traditional competitor into a co-opetitor. For the generalist intruder, data from the specialist firm substitute for its own investments in product quality in the secondary market. As such, the act of sharing data makes the intruder a stakeholder in the valuable data collected by the specialist, and consequently in the specialist’s continued success. Moreover, while the firms benefit from data sharing, consumers can be worse off from the weaker price competition and lower investments in innovation. Our results have managerial and policy implications, notably on account of backlash against data collection and the market power of big tech firms.

Interview Sequences and the Formation of Subjective Assessments

Author:

Jonas Radbruch (HU Berlin)
Amelie Schiprowski (University of Bonn)

Abstract:

Interviewing is a decisive stage of most processes that match candidates to firms and organizations. This paper studies how and why a candidate’s interview outcome depends on the other candidates interviewed by the same evaluator. We use large-scale data from high-stakes admission and hiring processes, where candidates are quasi-randomly assigned to evaluators and time slots. We find that the individual assessment decreases as the quality of other candidates assigned to the same evaluator increases. The influence of the previous candidate stands out, leading to a negative autocorrelation in evaluators’ votes of up to 40% and distorting final admission and hiring decisions. Our findings are in line with a contrast effect model where evaluators form a benchmark through associative recall. We assess potential changes in the design of interview processes to mitigate contrasting against the previous candidate.

From Couch to Poll: Media Content and The Value of Local Information

Author:

Bühler Mathias (LMU Munich)
Andrew Dickens (Brock University)

Abstract:

We document the importance of local information in mass media for the political engagement of citizens and accountability of politicians. We study this in the context of Canada, where until 1958, competition in television markets was suppressed—Canadians received either public or private television content, but never both. While public television provided national-level informational content, private television content was distinctly local and more politically relevant to voters. We find that the introduction of television reduced voter turnout, but that this effect is exclusive to public television districts. Our findings qualify existing knowledge about the political effects of the rollout of new media, by allowing the informational content to vary while holding the media type constant. We support this argument with evidence from parliamentary debates: politicians from districts with private television are more likely to speak and act on behalf of their constituents in Parliament. Our findings thus suggest that politicians are held accountable by relevant media content.

Insourcing Vs Outsourcing in Vertical Structure

Author:

Dongsoo Shin (Santa Clara University)
Roland Strausz (HU Berlin)

Abstract:

We study an agency model with vertical hierarchy---the principal, the prime-agent and the sub-agent. The principal faces a project that needs both agents' services. Due to costly communication, the principal receives a report only from the prime-agent, who receives a report from the sub-agent. The principal can directly incentivize each agent by setting individual transfers (insourcing), or sets only one overall transfer to an independent organization in which the prime-agent hires the sub-agent (outsourcing). We show that insourcing is always optimal when the principal can perfectly process the prime-agent's report. When the principal's information process is limited, however, outsourcing can be the prevailing mode of operation. In addition, insourcing under limited information process is prone to collusion between the agents, whereas no possibility of collusion arises with outsourcing.

Patents, Freedom to Operate, and Follow-on Innovation: Evidence from Post-Grant Opposition

Georg von Graevenitz (Queen Mary University of London)

Abstract:

We study the blocking effect of patents on follow-on innovation by others. We posit that follow-on innovation requires freedom to operate (FTO), which firms typically obtain through a license from the patentee holding the original innovation. Where licensing fails, follow-on innovation is blocked unless firms gain FTO through patent invalidation. Using large-scale data from post-grant oppositions at the European Patent Office, we find that patent invalidation increases follow-on innovation, measured in citations, by 16% on average. This effect exhibits a U-shape in the value of the original innovation. For patents on low-value original innovations, invalidation predominantly increases low-value followon innovation outside the patentee’s product market. Here, transaction costs likely exceed the joint surplus of licensing, causing licensing failure. In contrast, for patents on high-value original innovations, invalidation mainly increases high-value follow-on innovation in the patentee’s product market. We attribute this latter result to rent dissipation, which renders patentees unwilling to license out valuable technologies to (potential) competitors.

Does Online Fundraising Increase Charitable Giving? A Nationwide Field Experiment on Facebook

Author:

Maja Adena (WZB Berlin)
Anselm Hager (HU Berlin)

Abstract:

Does online fundraising increase charitable giving? Using the Facebook advertising tool, we implemented a natural field experiment across Germany, randomly assigning almost 8,000 postal codes to Save the Children fundraising videos or to a pure control. We studied changes in the donation revenue and frequency for Save the Children and other charities by postal code. Our geo-randomized design circumvented many difficulties inherent in studies based on click-through data, especially substitution and measurement issues. We found that (i) video fundraising increased donation revenue and frequency to Save the Children during the campaign and in the subsequent five weeks; (ii) the campaign was profitable for the fundraiser; and (iii) the effects were similar independent of video content and impression assignment strategy. However, we also found some crowding out of donations to other similar charities or projects. Finally, we demonstrated that click data may be an inappropriate proxy for donations and recommend that managers use careful experimental designs that can plausibly evaluate the effects of advertising on relevant outcomes.

Interpersonal Preferences and Team Performance: The Role of Liking in Complex Problem Solving

Author:

Timm Opitz (MPI-IC)

Abstract:

Organizations increasingly rely on teams to solve complex problems. The ability of teams to work well together is critical to their success. I experimentally test whether team performance is affected by whether team members like each other. I find that teams in which partners like each other do not outperform teams in which partners dislike each other. However, teams in which one partner likes the other more than the other perform best. The performance differences result directly from changes in collaborative behavior when learning the team partner's interpersonal preferences, not indirectly from interacting with different individuals. Participants do not anticipate this pattern and expect to be most successful in a team where partners like each other. This provides insights into how teams should be optimally composed, when self-selection may be detrimental to performance, and what information about others' interpersonal preferences should be revealed.

The Formation of Subjective House Price Expectations

Joachim Winter (LMU Munich)

Abstract:

Subjective house price expectations drive individual housing choices and market dynamics. We study the formation of subjective expectations about local house prices using novel survey data from Britain, a country with high homeownership rates and widely varying local housing dynamics. There is a substantial and heterogeneous perception gap and individuals extrapolate strongly from perceived but not from realized past price changes. In addition, expectations are predicted by wider, easily observable measures of local economic conditions, especially among individuals with low financial sophistication. Individuals residing in local housing markets where past prices are less informative or less observable rely more strongly on local economic conditions in their belief formation. Our results emphasize the role of heterogeneity in expectations formation processes, and their underlying information set.

Workplace Connections and Labor Migration: The Role of Information in Shaping Expectations

Author:

Michelle Hansch (HU Berlin)
Jan Nimczik (ESMT, RFBerlin, IAB, IZA)
Alexandra Spitz-Oener (HU Berlin, RFBerlin, IAB, IZA)

Abstract:

In a context where improved employment outcomes entail relocating to a new destination, how does information from former coworkers alter workers’ labor migration decisions? We explore this question using the unique backdrop of German reunification in the early 1990s. For former workers of the German Democratic Republic (GDR), improving employment outcomes typically meant relocating to West Germany, which most were reluctant to do. We show that information from former GDR coworkers in West Germany significantly increased the employment probability of East Germans in West Germany. To identify these network effects, we document and exploit that GDR workers were as-good-as randomly assigned to networks by the GDR system from the perspective of the West German market economy. We then establish that the networks only trigger migration responses among East Germans whose contacts had positive work experiences in the West and were similar in their earnings potential in the market-based economy of reunified Germany. These contacts, in essence, serve as role models for the workers’ prospects in the West, leading workers to trust the advice and assessments provided and ultimately altering the expected benefits from labor migration for the specific worker.

How to Increase Public Support for Carbon Pricing

Author:

Andrej Woerner (LMU Munich)
Taisuke Imai (University of Osaka)
Davide Pace (LMU Munich)
Klaus Schmidt (LMU Munich)

Abstract:

The public acceptability of a carbon price depends on how the revenues from carbon pricing are used. In a fully incentivised experiment with a large representative sample of the German population, we compare five different revenue recycling schemes and show that support for a carbon price is maximised by a “Climate Premium” that pays a fixed, uniform, upfront payment to each person. This recycling scheme receives more support than tax and dividend schemes, than using revenues for the general budget of the government, and than earmarking revenues for environmental projects. Furthermore, we show that participants and experts underestimate the public support for carbon pricing.
