Investigating the Dynamic Effects of Counterfeits with a Random Changepoint Simultaneous Equation Model

Qian, Yi - 2011

Using a unique panel dataset and a new model, this article investigates the dynamic effects of counterfeit sales on authentic-product price dynamics. We propose a Bayesian random-changepoint simultaneous equation model that simultaneously takes into account three important features in empirical...

Identification Through Heteroskedasticity : Measuring "Contagion: Betweenargentinean and Mexican Sovereign Bonds

Rigobon, Roberto - 2010

In this paper, I develop a new identification method to solve the problem of simultaneous equations, based on heteroskedasticity of the structural shocks. I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak...

Dynamic Seemingly Unrelated Cointegrating Regression

Mark, Nelson C.; Ogaki, Masao; Sul, Donggyu - 2021

Multiple cointegrating regressions are frequently encountered in empirical work as, for example, in the analysis of panel data. When the equilibrium errors are correlated across equations, the seemingly unrelated regression estimation strategy can be applied to cointegrating regressions to...

Identification and Estimation of Triangular Simultaneous Equations Models Without Additivity

Imbens, Guido W.; Newey, Whitney K. - 2021

This paper investigates identification and inference in a nonparametric structural model with instrumental variables and non-additive errors. We allow for non-additive errors because the unobserved heterogeneity in marginal returns that often motivates concerns about endogeneity of choices...

Dummy Endogenous Variables in a Simultaneous Equation System

Heckman, James J. - 2021

This paper considers the formulation and estimation of simultaneous equation models with both discrete and continuous endogenous variables. The statistical model proposed here is sufficiently rich to encompass the classical simultaneous equation model for continuous endogenous variables and more...

Aggregation of Consumer Ratings : An Application to Yelp.Com

Dai, Daisy - 2012

Because consumer reviews leverage the wisdom of the crowd, the way in which they are aggregated is a central decision faced by platforms. We explore this "rating aggregation problem" and offer a structural approach to solving it, allowing for (1) reviewers to vary in stringency and accuracy, (2)...

Politics 2.0 : The Multifaceted Effect of Broadband Internet on Political Participation

Campante, Filipe R. - 2013

We investigate the causal impact of broadband Internet on political participation using data from Italy. We show that … emergence of new political entrepreneurs who used the Internet to convert the initial "exit" back into "voice". Overall, these … nuanced effects underscore the general equilibrium dynamic induced by the Internet …
