Parameter Stability as a Diagnostic Tool for Production Function Specification.

The control function approach remains the dominant method for estimating production functions. In this framework, unobserved productivity is recovered by inverting a proxy function that relates it to observed state variables and flexible inputs. A key specification test proposed by Levinsohn and Petrín (2003) relies on the invariance of parameter estimates across different nonparametric proxies for flexible inputs. Given the widespread use of Cobb-Douglas production functions in empirical industrial organization, we propose a related test within the parametric inversion framework of Doraszelski and Jaumandreu (2013, hereafter DJ). Specifically, we demonstrate that under the identification assumptions of DJ, the recovered productivity process—and hence the structural parameter estimates—should be invariant to the choice of flexible input used for inversion. Consequently, systematic discrepancies across inversion strategies can serve as a diagnostic tool for detecting violations of the model’s underlying assumptions. Link

How Billing Rules Shape the Interpretation of Consumer Expenditure Data

Consumer expenditure surveys typically record regular household expenditures based on the most recent bill available at the time of the interview. Therefore, the resulting data must be interpreted with careful attention to the billing protocols. The aim of this paper is to show that failing to account for the rules governing the frequency and content of invoices can compromise empirical analyses based on consumer expenditure data. Changes in billing practices—such as the time span of reported consumption, the unit of measurement, or the timing at which consumption and prices are recorded—can significantly affect comparisons across different billing regimes. To illustrate these issues, we examine how Spanish electricity billing regulations—and changes therein—affect the data reported in the consumer expenditure survey. Building on this analysis, we revisit Labandeira, Labeaga, and Teixidó (2022) to show that their empirical approach overlooks several key billing protocols, thereby calling into question the robustness of their findings.
