Oil, Volatility, and Institutions

Federal Reserve Bank of Dallas, Globalization and Monetary Policy Institute Working Papers, 2017
This chapter examines the long-run effects of oil revenue and its volatility on economic growth, as well as the role of institutions in this relationship. We collect annual and monthly data on 17 major oil producers between 1961 and 2013, and use the panel autoregressive distributed lag (ARDL) approach as well as its cross-sectionally augmented version

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Shaping Carbon Nitrides for Advanced Macrostructures

Advanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Volatility of Oil Prices

IMF Working Papers, 1996
This paper examines the behavior of crude oil prices since 1980, and in particular the volatility of these prices. The empirical analysis covers “spot” prices for one of the key internationally traded crudes, namely Dated Brent Blend. A GARCH (generalized autoregressive conditional heteroscedastic) model, which allows the conditional variance to be ...
