We argue that job performance appraisal is an agency problem with asymmetric transfer values: an employee is paid in proportion to the rating received from his line manager, who only partially internalizes the resultant payroll cost. This asymmetry in rating valuations is based on evidence that...

What determines reciprocity in employment relations? We conducted a controlled field experiment to measure the extent to which monetary and non-monetary gifts affect workers’ performance. We find that non-monetary gifts have a much stronger impact than monetary gifts of equivalent value. We...

Awards—widespread in the corporate sector and elsewhere—are motivators that derive their value from non-pecuniary concerns such as status and self-image. Quasi-experimental panel data from the call center of a large international bank allow us to estimate the causal impact on effort when...

Employment contracts are often incomplete, leaving many responsibilities subject to workers’ discretion. High work morale is therefore essential for sustaining voluntary cooperation and high productivity in firms. We conducted a field experiment to test whether workers reciprocate wage cuts...

In recent decades, many firms offered more discretion to their employees, often increasing the productivity of effort but also leaving more opportunities for shirking. These “high-performance work systems” are difficult to understand in terms of standard moral hazard models. We show...

Academic rankings today are the backbone of research governance, which seem to fit the aims of “new public management” on the one side and the idea of the “republic of science” on the other side. Nevertheless rankings recently came under scrutiny. We discuss advantages and disadvantages...

Although the relationship between natural resources and civil war has received much attention, little is known about the underlying mechanisms. Controversies and contradictions in the stylized facts persist because resource extraction is treated as exogenous while in reality fighting affects...

Since World War II there have been about fifty episodes of large-scale mass killings of civilians and massive forced displacements. They were usually meticulously planned and independent of military goals. We provide a model where conflict onset, conflict intensity and the decision to commit...

The UNESCO World Heritage List contains the 900 most treasured Sites of humanity’s culture and landscapes. The World Heritage List is beneficial where heritage sites are undetected, disregarded by national decision-makers, not commercially exploitable, and where national financial resources,...

Museums have many different goals beyond efficiency such as social equity, financial revenue, attracting donors and gaining international, regional or local prestige. Various pricing schemes are being discussed with the aim of reaching these goals. The classical ones are entry prices and free...
