This theoretical contribution shows a simple way in which the quantity equation can be derived as a long-term equilibrium solution for the case of a closed economy and an open economy, respectively. It is shown first for the case of a closed economy which parameters stand behind "velocity" and...

In a market in which sellers compete for heterogeneous buyers by posting mechanisms, we analyze how the properties of the meeting technology affect the allocation of buyers to sellers. We show that a separate submarket for each type of buyer is the efficient outcome if and only if meetings are...

Employer learning about workers' abilities plays a key role in determining how workers sort into jobs and are compensated. This study explores whether learning is symmetric or asymmetric, i.e., whether potential employers have the same information about worker ability as the incumbent firm. I...

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...

Embezzlement is a major concern in various settings. By means of a sequential modified dictator game, we investigate theoretically and experimentally whether making information more transparent and reducing the number of intermediaries in transfer chains can reduce embezzlement and improve the...

This paper extends the job market signaling model of Spence (1973) by allowing firms to learn the ability of their employees over time. Contrary to the model without employer learning, we find that the Intuitive Criterion does not always select a unique separating equilibrium. When the Intuitive...

This paper focuses on indivisible multiple-cost-single-benefit projects that must be approved by the government. A simple mechanism is proposed that ensures an efficient and fair implementation of such projects. The proposed mechanism is appropriate for a unilateral information structure: the...

COVID-19 is spreading and has reached the state of a worldwide pandemic and health systems are or will be tested in how they can deal with it. So far, during this early phase of the pandemic, outcomes in terms of case-fatality rates (CFR) differ widely across countries. We explore how...

This paper proposes a new approach to evaluate the macroeconomic effects of the Hartz IV reform in Germany, which reduced the generosity of long-term unemployment benefits. We use a model with different unemployment durations, where the reform initiates both a partial effect and an equilibrium...

Prior to 2020, the Great Recession was the most important macroeconomic shock to the United States economy in generations. Millions lost jobs and homes. At its peak, one in ten workers who wanted a job could not find one. On an annual basis, the economy contracted by more than it had since the...
