Rising to the Challenge : Bayesian Estimation and Forecasting Techniques for Macroeconomic Agent-Based Models
Delli Gatti, Domenico - 2019
We propose two novel methods to "bring ABMs to the data". First, we put forward a new Bayesian procedure to estimate the numerical values of ABM parameters that takes into account the time structure of simulated and observed time series. Second, we propose a method to forecast aggregate time...

Reverse Bayesianism : Revising Beliefs in Light of Unforeseen Events
Becker, Christoph K.; Melkonyan, Tigran; Proto, Eugenio; … - 2021
Bayesian updating is the dominant theory of learning. However, the theory is silent about how individuals react to events that were previously unforeseeable or unforeseen. Building on a recently developed axiomatic framework to analyze such situations, we test if subjects update their beliefs...

Bayesian Estimation of Epidemiological Models : Methods, Causality, and Policy Trade-Offs
Arias, Jonas; Fernández-Villaverde, Jesús; Rubio … - 2021
We present a general framework for Bayesian estimation and causality assessment in epidemiological models. The key to our approach is the use of sequential Monte Carlo methods to evaluate the likelihood of a generic epidemiological model. Once we have the likelihood, we specify priors and rely...

Exchange Rate Elasticities of International Tourism and the Role of Dominant Currency Pricing
Ding, Ding; Timmer, Yannick - 2022
We estimate exchange rate elasticities of international tourism. We show that, in addition to the bilateral exchange … rate, the exchange rate between the tourism origin country vis-à-vis the U.S. dollar is an important driver of tourism … flows, indicating a strong role of U.S. dollar pricing. The U.S. dollar exchange rate is more important for tourism …
