Linear panel models, and the "event-study plots" that often accompany them, are popular tools for learning about policy effects. We discuss the construction of event-study plots and suggest ways to make them more informative. We examine the economic content of different possible identifying...

We study treatment-effect estimation, with a panel where groups may experience multiple changes of their treatment dose. We make parallel trends assumptions, but do not restrict treatment effect heterogeneity, unlike the linear regressions that have been used in such designs. We extend the...

This paper addresses two questions: (i) how do governments actually pay for the fiscal costs associated with currency crises; and (ii) what are the implications of different financing methods for post-crisis rates of inflation and depreciation? We study these questions using a general...

The paper studies the solvency of the Indian public sector and the eventual monetization and inflation implied by stabilization of the debt-GNP ratio without any changes in the primary deficit. The nonstationarity of the discounted public debt suggests that indefinite continuation of the pattern...

Linear panel models featuring unit and time fixed effects appear in many areas of empirical economics. An active literature studies the interpretation of the ordinary least squares estimator of the model, commonly called the two-way fixed effects (TWFE) estimator, in the presence of unmodeled...

This note presents a simple, linear test for individual effects in dynamic models using panel data; building upon the techniques of Holtz-Eakin, Newey, and Rosen (HNR) [198S] for estimating vector autoregressions using panel data. While implementing estimators which are consistent in the presence...

In this paper, we investigate the problem of estimating distributed lags in short panels. Estimates of the parameter of distributed lag relationships based on single time-series of observations have been usually rather imprecise. The promise of panel data in this context is in the N repetitions...

This paper considers why the determinants of the inter- and intra-industry variance in R&D intensity in U.S. manufacturing differ markedly even though response parameters are similar across industries. A similar aggregation effect is noted by Grunfeld and Griliches (1960), and this paper gives...
