Commodity polyester plastics such as PET, PBT, and PEN are hydrogenolytically deconstructed to their starting monomeric carboxylic acids light alkanes using a solventless tandem catalytic approach with two air- moisture-stable catalysts, Hf(OTf)4 Pd/C. These selective reactions operate near the polymer melting temperature under 1 atm H2 compatible mixed plastics, reported by Yosi Kratish Tobin ...

The apparent inconsistency between the Tobin Separation Theorem and the advice of popular investment advisors pointed out by Canner et al (1997) is shown to be explicable in terms of the hedging demands of optimising long-term investors in an environment in which the investment opportunity set is subject to stochastic shocks. ∗Goldyne and Irwin Hearsh Professor of Banking and Finance, Universit...

That MNCs communicate concern for the natural environment in order to suggest that they are operating in an environmentally responsible manner to stakeholders is well known (Deegan, Rankin & Tobin, 2002). Communicating concern for the natural environment has been shown to reduce NGO and government scrutiny (Delmas, 2001) and influence stock price (Bansal & Roth, 2000). Research has also suggest...

We develop a model of “intrinsic” cycles, driven by the decentralized behaviour of entrepreneurs and Þrms making continuous, divisible improvements in their productivity. We show that when the introduction of productivity impovements is endogenous, implementation cycles arise even in the presence of reversible investment and consumption—smoothing. The implied cyclical equilibrium is unique with...

Controls on short-term capital inflows or panic-driven capital outflows may benefit emerging markets with fragile financial sectors and adjustable-peg currency regimes. However, the controls seen so far are relatively easy to evade, often complex and obscure, and supported by large corruptible bureaucracies. A tax on foreign-exchange payments avoids these drawbacks. It is transparent, inexpensi...
