摘要：Many e-commerce platforms use buyers' personal data to intermediate their transactions with sellers. How much value do such intermediaries derive from the data record of each single individual? We characterize this value and find that one of its key components is a novel externality between records, which arises when the intermediary pools some records to withhold the information they contain. Our analysis has several implications about compensating individuals for the use of their data, guidi...

摘要：We design a laboratory experiment to study bargaining behaviour when negotiations involve multiple issues. Parties must discover both trading prices and agreement scopes, giving rise to unexplored information structures and bargaining strategies. We find that bargainers often trade the efficient set of issues despite lacking information about individual aspects. However, beneficial agreements critically hinge on integrated negotiations that allow deals on bundles of issues. Moreover, access to...

摘要：We study partially linear models when the outcome of interest and some of the covariates are observed in two different datasets that cannot be linked. This type of data combination problem arises very frequently in empirical microeconomics. Using recent tools from optimal transport theory, we derive a constructive characterization of the sharp identified set. We then build on this result and develop a novel inference method that exploits the specific geometric properties of the identified set....

摘要：We consider the effects of climate change on seasonally migrant populations that herd livestock-i.e. transhumant pastoralists-in Africa. Traditionally, transhumant pastoralists benefit from a cooperative relationship with sedentary agriculturalists whereby arable land is used for crop farming in the wet season and animal grazing in the dry season. Rainfall scarcity can disrupt this arrangement by inducing pastoral groups to migrate to agricultural lands before the harvest, causing conflict to ...

摘要：We consider a procurement auction for the provision of a basic service to which an add-on must later be appended. Potential providers are symmetric, have private information on their cost for the basic service and the winning firm must also implement the add-on. To finance value-enhancing activities related to the add-on, this firm may need extra funding by outside financiers. Nonverifiable effort related to these activities creates a moral hazard problem which makes the firm's payoff function...

摘要：We study dynamic signalling when the sender does not see the signals that her actions generate. The sender then uses her past play to forecast what a receiver believes, in turn forcing the receiver to forecast the previous forecast, and so forth. We identify a class of linear-quadratic-Gaussian games where this endogenous higher-order uncertainty can be handled. The sender's second-order belief is key: it is a private state that she controls, and it creates a new channel for information transm...

摘要：How should the government respond to automation? We study this question in a heterogeneous agent model that takes worker displacement seriously. We recognize that displaced workers face two frictions in practice: reallocation is slow and borrowing is limited. We analyze a second best problem where the government can tax automation but lacks redistributive tools to fully alleviate borrowing frictions. The equilibrium is (constrained) inefficient and automation is excessive. Firms do not interna...

摘要：Interviewing is a decisive stage of most processes that match candidates to firms and organizations. This article 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 in...

摘要：How do innovation and education policy affect individual career choices and aggregate productivity? This paper analyses the effect of R&D subsidies and higher education policy on productivity growth through the supply of innovative talent. We put scarce talent, higher education attainment, and career choice at the centre of a new endogenous growth framework with individual-level heterogeneity in talent, financial resources, and preferences. We link the model to micro-level data from Denmark on...

摘要：We develop a model of size-based market power in a frictional labour market. In the canonical search environment, competition for workers is encoded in outside options. In our granular setting, large employers remove their own job postings from their workers' outside option. Thus, size gives market power and a more concentrated market structure depresses wages because it reduces competition for workers. We calibrate the model to Austrian data and find that such size-based market power depresse...
