A hornet's nest could be an apt simile for fossil fuel prices in India. Over years a policy maze has evolved around it, with sharply diverging influence on disparate constituencies. We estimate the increase in total cost of farming as a multiple of direct input costs of fossil fuels in farming....

Minimization of damage from the rising trend of global warming would warrant two kinds of action for a country like India: a) abatement of greenhouse gas emissions and b) adaptation to climate change so as to reduce climate change related vulnerability of the people. The target of low carbon...

The article studies the macroeconomic impact of oil price changes in 17 highly heterogeneous countries classified in six groups: advanced, emerging, oil producer, non-oil producers, with energy price controls and without energy price controls. The results show that despite analyzed countries...

Traditional climate policy is based on the market-liberal paradigm that relies on carbon pricing, a belief in self-regulating markets, and transfer payments for the so-called "losers" of the transfor- mation process. The market-liberal approach to climate policy is certain to fail because it is...

This study analyzes the short-run effects on the German economy of the fossil energy crisis in 2022 and discusses some implications for the design of a resilient, renewable energy system. The study shows that the energy crisis led to a short-run output loss comparable to the output losses...

In the wake of the global energy crisis, many European countries used energy price controls to fight inflation and to stabilize the economy. Despite its wide adoption, many economists remained skeptical. In this paper, we argue that price controls should be part of the policy toolbox to respond...

A barrier option is a financial derivative which includes an activation (or deactivation) clause within a standard vanilla option. For instance, a copper mining company could secure to sell in at least K dollars each ton of copper during the next year, by buying M European put options. However,...

We investigate financial markets under model risk caused by uncertain volatilities. For this purpose we consider a financial market that features volatility uncertainty. To have a mathematical consistent framework we use the notion of G-expectation and its corresponding G-Brownian motion...

We consider fundamental questions of arbitrage pricing arising when the uncertainty model is given by a set of possible mutually singular probability measures. With a single probability model, essential equivalence between the absence of arbitrage and the existence of an equivalent martingale...

We investigate American options in a multiple prior setting of continuous time and determine optimal exercise strategies form the perspective of an ambiguity averse buyer. The multiple prior setting relaxes the presumption of a known distribution of the stock price process and captures the idea...
