The Effect of Incentives in Non-Routine Analytical Team Tasks - Evidence From a Field Experiment
Author:
Abstract:
Despite the prevalence of non-routine analytical team tasks in modern economies, little is known about how incentives influence performance in these tasks. In a field experiment with more than 3000 participants, we document a positive effect of bonus incentives on the probability of completion of such a task. Bonus incentives increase performance due to the reward rather than the reference point (performance threshold) they provide. The framing of bonuses (as gains or losses) plays a minor role. Incentives improve performance also in an additional sample of presumably less motivated workers. However, incentives reduce these workers' willingness to "explore" original solutions.

The Impact of a Negative Labor Demand Shock on Fertility - Evidence From the Fall of the Berlin Wall
Author:
Abstract:
How does a negative labor demand shock impact fertility? I analyze this question in the context of the East German fertility decline after the fall of the Berlin Wall in 1989. I exploit differential pressure for restructuring across East German industries which led to unexpected, exogenous, and permanent changes to labor demand. I find that throughout the 1990s, women more severely impacted by the demand shock had relatively more children than their less-severely-impacted counterparts. Thus, the demand shock did not only depress the aggregate fertility level but also changed the composition of mothers. My paper shows that these two effects do not necessarily operate in the same direction.

Signal Sell: Product Lines when Consumers Differ Both in Taste for Quality and Image Concern
Author:
Abstract:
This paper analyzes optimal product lines when consumers differ both in their taste for quality and in their desire for social image. The market outcome features partial pooling and product differentiation that is not driven by heterogeneous valuations for quality but by image concerns. A typical monopoly outcome is a two-tier product line resembling a "masstige" strategy as observed in luxury goods markets. Products can have identical quality and differ only in price and image, thereby rationalizing quality-equivalent line extensions. Under competition, both average quality and market coverage are (weakly) higher but monopoly can yield higher welfare than competition.

Matching with Waiting Times: The German Entry-Level Labor Market for Lawyers
Author:
Abstract:
We study the allocation of German lawyers to regional courts for legal trainee-ships. Because of excess demand in some regions lawyers often have to wait before being allocated. The currently used "Berlin" mechanism is not weakly Pareto efficient, does not eliminate justified envy and does not respect improvements. We introduce a mechanism based on the matching with contracts literature, using waiting time as the contractual term. The resulting mechanism is strategy-proof, weakly Pareto efficient, eliminates justified envy and respects improvements. We extend our proposed mechanism to allow for a more flexible allocation of positions over time.

Privacy and Platform Competition
Author:
Abstract:
We analyze platform competition where user data is collected to improve adtargeting. Considering that users incur privacy costs, we show that the equilibrium level of data provision is distorted and can be inefficiently high or low: if overall competition is weak or if targeting benefits are low, too much private data is collected, and vice-versa. Further, we find that softer competition on either market side leads to more data collection, which implies substitutability between competition policy measures on both market sides. Moreover, if platforms engage in two-sided pricing, data provision is efficient.

Learning From Unrealized versus Realized Prices
Author:
Abstract:
Our experiments investigate the extent to which traders learn from the price, differentiating between situations where orders are submitted before versus after the price has realized. In simultaneous markets with bids that are conditional on the price, traders neglect the information conveyed by the hypothetical value of the price. In sequential markets where the price is known prior to the bid submission, traders react to price to an extent that is roughly consistent with the benchmark theory. The difference's robustness to a number of variations provides insights about the drivers of this effect.

Strategic Decentralization and the Provision of Global Public Goods
Author:
Abstract:
We study strategic decentralization in the provision of a global public good. A federation, with the aim of maximizing the aggregate utility of its members, may find it advantageous to decentralize the decision-making, so that its members act autonomously to maximize their own utility. If utility is fully transferable within a federation, the larger a federation is or the more sensitive it is to the public good, the more it has incentives to remain centralized. If an overall increase in the sensitivity to the public good induces some federation(s) to decentralize, it may lead to a decrease in the aggregate provision. With non-transferable utility within a federation, those members that are smaller or less sensitive to the public good are more likely to prefer decentralization. Some members within a federation becoming more sensitive to the public good may thus lead to a lower aggregate provision, because the increased heterogeneity of the federation makes it more inclined to decentralize.

Fairness in Markets and Market Experiments
Author:
Abstract:
Whether pro-social preferences identified in economic laboratories survive in natural market contexts is an important and contested issue. We investigate how fairness in a laboratory experiment framed explicitly as a market exchange relates to preferences for fair trade products before and after the market experiment. We find that the willingness to buy at a higher price when higher wages are paid to the worker correlates both with the choice for a fair trade product before the laboratory experiment and with whether the participants are willing to pay a positive fair trade premium, elicited at the end of the experiment. These results support the notion that fairness preferences as assessed in laboratory experiments capture preferences for fair behavior in comparable situations outside the laboratory.

Skills, Signals, and Employability: An Experimental Investigation
Author:
Abstract:
As skills of labor-market entrants are usually not directly observed by employers, individuals acquire skill signals. To study which signals are valued by employers, we simultaneously and independently randomize a broad range of skill signals on pairs of resumes of fictitious applicants among which we ask a large representative sample of German human-resource managers to choose. We find that signals in all three studied domains - cognitive skills, social skills, and maturity - have a significant effect on being invited for a job interview. Consistent with the relevance, expectedness, and credibility of different signals, the specific signal that is effective in each domain differs between apprenticeship applicants and college graduates. While GPAs and social skills are significant for both genders, males are particularly rewarded for maturity and females for IT and language skills. Older HR managers value school grades less and other signals more, whereas HR managers in larger firms value college grades more.

Size Matters - 'Over'investments in a Relational Contracting Setting
Author:
Abstract:
The corporate finance literature documents that managers tend to over-invest in their companies. A number of theoretical contributions have aimed at explaining this stylized fact, most of them focusing on a fundamental agency problem between shareholders and managers. The present paper shows that over-investments are not necessarily the (negative) consequence of agency problems between shareholders and managers, but instead might be a second-best optimal response to address problems of limited commitment and limited liquidity. If a firm has to rely on relational contracts to motivate its workforce, and if it faces a volatile environment, investments into general, non-relationship-specific, capital can increase the efficiency of a firm's labor relations.
