Optimal Discounts in Green Public Procurement

We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...

Estimating Demand with Multi-Homing in Two-Sided Markets

We empirically investigate the relevance of multi-homing in two-sided markets. First, we build a micro-founded structural econometric model that encompasses demand for differentiated products and allows for multi-homing on both sides of the market. We then use an original dataset on the Italian daily newspaper market that includes information on double-homing by readers to estimate readers’ and advertisers’ ...

Mexico and U.S. Power Systems under Variations in Natural Gas Prices

This study examines the impact of natural gas prices on the power systems of Mexico and the United States. For this, we develop an integrated modeling framework by soft linking three different techno-economic bottom-up models of the power and energy systems, one partial equilibrium model of the natural gas sector, and a partial equilibrium model of the Mexican energy sector. Our results show several ...

The Effect of Changing Marginal-Cost to Physical-Order Dispatch in the Power Sector

The analysis of local environmental policies is essential when evaluating the consistency of national public policies vis-à-vis the compliance of global agreements to reduce climate change. This study explores one of these policies; the 2021 Mexican reform to change electric power dispatch from a marginal-cost-based to a command and control physical system prioritizing power generation from the state ...

Energy Transition Metals

The energy transition requires substantial amounts of metals such as copper, nickel, cobalt and lithium. Are these metals a key bottleneck? We identify metal-specific demand shocks, estimate supply elasticities and pin down the price impact of the energy transition in a structural scenario analysis. Metal prices would reach historical peaks for an unprecedented, sustained period in a net-zero emissions ...

Market Concentration in Europe: Evidence from Antitrust Markets

An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level while firm level revenues are a poor indicator of product sales. We use a novel database that identifies over ...

Accounting for Spatiality of Renewables and Storage in Transmission Planning

The current governance process to plan the German energy system omits two options to substitute grid expansion: First, placing renewables closer to demand instead of where site conditions are best. Second, utilizing storage instead of additional transmission infrastructure to prevent grid congestion. In the paper, we apply a comprehensive capacity expansion model based on the AnyMOD modeling framework ...

ECB Can Lower Fuel and Heating Costs by Increasing Interest Rates but Would Risk Economic Recovery

Inflation has been growing considerably since the middle of 2021, with rising energy prices driving the increase in particular. Since the end of February 2022, the trend has also been exacerbated by the ongoing Russian invasion of Ukraine. To keep prices stable, the European Central Bank must rein in its accommodative monetary policy. However, would doing so—by enacting an interest rate increase, for ...
