Climate Change, Uncertainty, and Policy
, 2021 While the foundations of climate science and ethics are well established, fine-grained climate predictions, as well as policy-decisions, are beset with uncertainties. This chapter maps climate uncertainties and classifies them as to their ground, extent and location.

Monetary Policy and Uncertainty about the Natural Unemployment Rate [PDF]
Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment.

Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction
Advanced Materials, EarlyView.CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

Risk and Policy Uncertainty on Stock–Bond Return Correlations: Evidence from the US Markets
Risks, 2020 This paper investigates dynamic correlations of stock–bond returns for different stock indices and bond maturities. Evidence in the US shows that stock–bond relations are time-varying and display a negative trend.

Policy Uncertainty, Electoral Securities and Redistribution [PDF]
SSRN Electronic Journal, 2008 This article investigates how uncertainty about the adoption of a redistribution policy affects political support for redistribution when individuals can trade policy‐contingent securities in the stock market. In equilibrium the support for redistribution is smaller than where no “policy‐insurance market” is available.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?
Advanced Robotics Research, EarlyView.Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

Regional trade policy uncertainty
Journal of International EconomicsHigher uncertainty about trade policy has recessionary effects in U.S. states. First, this paper builds a novel empirical measure of regional trade policy uncertainty, based on the volatility of national import tariffs at the sectoral level and the sectoral composition of imports in U.S. states.
