"Local Inference in General Long Memory Series"
Abstract A generalization of the Exact Local Whittle estimator in Shimotsu and Phillips (2005) was proposed in Arteche (2020) for jointly estimating all the memory parameters in general long memory time series that possibly display standard, seasonal and/or other cyclical strong persistence. Its asymptotic properties permit straightforward standard inference based on Wald statistics of interesting hypotheses such as the existence of unit roots and equality of memory parameters at some or all seasonal frequencies, which can be used as a prior test for the application of seasonal differencing filters. Lagrange Multiplier-type tests, which avoid the need to estimate the memory parameters, are proposed here as a means of testing for the existence of long memory of any degree at any set of frequencies. The tests are applicable to both stationary and non-stationary as well as to invertible and non-invertible series exhibiting any type of standard, cyclical or seasonal persistence. No estimation of parameters or specification of short memory behaviour is required, as the tests are based on a local spectral specification around the frequencies of interest. Standard inference can be implemented thanks to the chisquared asymptotic distribution under the null hypothesis. The testing strategy is shown to be consistent against constant departures from the null hypothesis and the asymptotic distribution of the test statistics under local alternatives is also shown. Finally, the robustness of the tests to the presence of some deterministic components is shown.

"Causal inference with auxiliary observations" with Takahiro Hoshino (Keio University), Taisuke Otsu（London School of Economics）
Abstract In the evaluation of social programs, it is often difficult to conduct randomized controlled experiments due to non-compliance; therefore the local average treatment effect (LATE) is commonly applied. However, the LATE identifies the average treatment effect only for a subpopulation known as compliers and requires the monotonicity assumption. Given these limitations of the LATE, this paper proposes a nonparametric strategy to identify the causal effects for larger populations (such as the ATT and ATE) and to remove the monotonicity assumption in the cases of non-compliance. Our strategy utilizes two types of auxiliary observations, one is an outcome before assignment and the other is a treatment before assignment. These observations do not require specially designed experiments, and are likely to be observed in baseline surveys of the standard experiment or panel data. We show the results for the random assignment and those of multiply robust representations in the case where the random assignment is violated. We then present details of the GMM estimation and testing methods which utilize over-identified restrictions. The proposed strategy is illustrated by empirical examples which revisit the studies by Thornton (2008), Gerber et al. (2009), and Beam (2016), as well as the data set from the Oregon Health Insurance Experiment and that from an experimental data on marketing in a private sector.
