The Unassuming Economist

From a new paper by Tarek Atalla, Simona Bigerna and Carlo Andrea Bollino:

“In the global carbon policy debate, pricing is considered to be a key instrument to achieving the desired levels of emissions reductions.

The Pigouvian tax is theoretically the best solution to tax carbon emissions, in order to achieve emissions reduction through financial investment, but it has not proved to be politically viable. A Pigouvian tax sets out to correct negative externalities, or consequences for society – such as the consequences of climate change – by levying additional taxes. However, from the viewpoint of the private sector, such taxation imposes a deadweight loss with respect to the original private equilibrium. This generates political resistance that may impede achieving the theoretical optimal solution.

Most international policy meetings since the Kyoto Protocol agreement have resulted in lukewarm commitments from developed economies and strong resistance from emerging economies over the fair economic allocation of the burden associated with the various calls for emissions reduction. This kind of situation suggests the need for alternative formulations, in the realm of what economists call ‘second-best options,’ to tackle the issue of realistically financing alternative policies.

This paper considers alternative policy formulation aimed at funding investment for climate policies, based on the principle of minimizing deadweight losses associated with taxation and on consumer preferences. (A deadweight loss is the added burden placed on consumers and suppliers when the market equilibrium is altered because of tax, for example. It results when supply and demand are out of equilibrium.)

The policy proposal we examine here is a Ramsey allocation, which aims at designing an economically optimal taxation scheme for financing climate mitigation investments. A Ramsey pricing policy, applied to energy prices, would mean that efficient taxation should be inversely proportional to the consumer (household) energy demand elasticity of the individual country. In other words, the more inelastic a country’s consumer energy demand, the higher the efficient taxation should be in that country. The overall taxation scheme is optimal because it minimizes the deadweight loss.

This strategy is not aimed at directly reducing emissions, and hence energy consumption. It can, in a more general way, help to assist with providing efficient funding for a wider range of policies, such as carbon sequestration, alternative fuels, energy efficiency, and the earth’s albedo enhancing. In this framework, notice that carbon sequestration and artificially enhancing the earth’s albedo represent technological solutions aimed at reducing carbon dioxide (CO2) concentration and adding sunlight reflecting aerosol in the soil
or stratosphere, thereby cooling the climate in a different way than reducing carbon emissions (NAS 1992). The strategy makes explicit use of household preferences, as expressed through their energy demand behavior, econometrically estimated at the world level.

A Ramsey allocation can be integrated into the general principle of mutual cooperation that motivates climate agreements, as it reflects a common but differentiated burden of all parties.”

From a new IMF working paper by Bertrand Gruss and Suhaib Kebhaj:

“This paper presents a comprehensive database of country-specific commodity price indices for 182 economies covering the period 1962-2018. For each country, the change in the international price of up to 45 individual commodities is weighted using commodity-level trade data. The database includes a commodity terms-of-trade index which proxies the windfall gains and losses of income associated with changes in world price as well as additional country-specific series, including commodity export and import price indices. We provide indices that are constructed using, alternatively, fixed weights (based on average trade flows over several decades) and time-varying weights (which can account for time variation in the mix of commodities traded and the overall importance of commodities in economic activity). The paper also discusses the dynamics of commodity terms of trade across country groups and their influence on key macroeconomic aggregates.”

A new working paper by Nida Cakir Melek, Michael Plante, Mine K. Yucel:

“We examine the implications of the U.S. shale oil boom for the U.S. economy, trade balances, and the global oil market. Using comprehensive data on different types of crude oil, and a two-country general equilibrium model with heterogenous oil and refined products, we show that the shale boom boosted U.S. real GDP by 1 percent and improved the oil trade balance as a share of GDP by more than 1 percentage points from 2010 to 2015. The boom led to a decline in oil and fuel prices, and a dramatic fall in U.S. light oil imports. In addition, we find that the crude oil export ban, which was in place during a large part of this boom, was a binding constraint, and would likely have remained a binding constraint thereafter had the policy not been removed at the end of 2015.”

From a new working paper by Myunghyun Kim:

“This paper studies international transmission of U.S. monetary policy shocks to commodity exporters and importers. After first showing empirically that the shocks have stronger effects on commodity exporters than on importers, I then augment a standard three-country model to include commodities. Consistent with the empirical evidence, the model
indicates that an expansionary monetary policy shock to the U.S. increases the aggregate output of commodity exporters by more than that of importers. This is because the increased U.S. aggregate demand triggered by the shock leads to greater U.S. demand for commodities and higher real commodity prices, and thus the exports of commodity exporters increase relative to those of commodity importers. Furthermore, I show that if commodity exporters’ currencies are pegged to the U.S. dollar, then the U.S. monetary policy shocks have stronger spillovers to commodity exporters and importers. In the event that the U.S. becomes a net energy exporter, the shocks will have weaker effects on commodity exporters and stronger impacts on importers.”
