Inflation Transmission Diagnostics via a Bayesian Graph Vector Autoregressive Model with Markov Switching

Journal of Systems Science & Complexity 2024年

The transmission of inflation is a widespread occurrence, and managing inflationary pressures is a crucial macroeconomic challenge. Although inflation is a typical macroeconomic variable,its contemporaneous and lagged causal relationships have not been thoroughly investigated, which could result in missing important policy insights. The Bayesian graph vector autoregression(BGVAR)model can identify contemporaneous and lagged causal relationships among economic variables, but it lacks practical research on inflationary inflation. To account for the structural transformation in the inflation transmission process, the authors propose a Bayesian graph vector autoregressive model with Markov switching(MS-BGVAR), which considers both regime switching and contemporaneous causality among macroeconomic variables. The proposed study focuses on analyzing the dynamics of inflation transmission relationships among G7 countries under different regimes, as these countries represent developed nations. The authors use inflation data from 1971–2019, which shows two distinct inflation regimes within the sample period. The authors conduct simulation experiments to generate moderately dimensional simulated data for both regimes and indicators, demonstrating the theoretical reliability of the proposed model in accurately identifying graph structures. Finally, the authors apply the proposed model to identify structural breaks and causal transmission relationships in the inflation transmission process of G7 economies, demonstrating that the proposed model has significant economic significance and good explanatory power in the selected target countries.

New potential barite reference materials for LA-MC-ICP-MS sulfur isotope analysis with application to hydrothermal barite in the Huayangchuan deposit， western China

Journal of Earth Science 2024年

Sulfur isotopes of S-bearing materials are powerful tools to trace various geological processes and sulfur sources in earth sciences， especially in ore deposits where sulfide-sulfate pair coprecipitates widely. However， in-situ S isotope determination of barite is challenging without natural matrix-matched reference material. In this study， we present two natural barite reference materials （1-YS and 294-YS） for in-situ sulfur isotopic analysis. Independent LA-MC-ICP-MS laboratories were utilized to test the δ34S micron-scale homogeneity of 1-YS and 294-YS barites that have 2s repeatabilities of better than ±0.45 ‰ and ±0.41 ‰， respectively. Meanwhile， the in-situ analysis results are consistent with the results of the bulk analysis by GS-IRMS within uncertainty. The grand mean δ34S values of 1-YS （13.37‰ ± 0.42 ‰， 2s） and 294-YS （14.38‰ ± 0.44 ‰， 2s） are the final recommended values obtained from four independent laboratories. All the results confirm the suitability of 1-YS and 294-YS barite used as calibration materials with respect to in-situ S isotopic analysis. Moreover， the new developed barite reference materials were used as matrix-matched standard to calibrate the barite samples from the Huayangchuan carbonatite-hosted U-polymetallic deposit （Qinling orogenic belt， western China） to obtain δ34S values. Utilizing the temperature-dependent δ34S fractionation of barite-pyrite pair， we calculate the formation temperature of barite （i.e.， 506 to 537 ℃） and the δ34S value of mineralizing fluid （i.e.， -7.11‰ to -7.59 ‰） in the Huayangchuan deposit. The results indicate an involvement of sedimentary sulfur， presumably acting as a potential uranium source （e.g.， upper crustal materials） for the giant Huayangchuan deposit.
