Price Co-Movement between Electrical Equipment and Metal Commodities—A Time-Frequency Analysis

نویسندگان

چکیده

The rising uncertainty of the global markets has caused price fluctuation equipment and materials in PT&D (Power Transmission Distribution) projects to be more complicated. As cost accounts for a large proportion total investment projects, this study investigates co-movement metal commodities’ with use wavelet coherency partial analysis under time-frequency framework. Our results indicate that (i) manifests mainly short term long term; (ii) there is no clear lead-lag relationship co-movement; (iii) short-term activated by continuous commodity price; (iv) long-term largely driven overall market movement, but effect weakened when high importance producing equipment. shed light on planning both purchase production sides.

Analysis of the Relationship between the Business Cycle and Inflation Gap in Time-Frequency Domain

Controlling the business cycle and minimizing the inflation gap are considered as two major goals for monetary policy. Hence, the policymaker will be able to make more decisive decisions with an awareness of the dynamic relationship and causal relationship between these two variables. Accordingly, the present study uses a discrete and continuous wavelet transform to provide a new understanding ...
