To help households and firms with exploding energy costs in the aftermath of the Ukraine war, a new policy called the "energy price brake" was implemented. A unique feature of this relief measure is that it provides a transfer that increases in the consumer's contractual per-unit price of...

To support the green transition in the automotive sector, the EU has introduced CO2 emission performance standards, also known as the excess emissions premium (EEP) regulation, which will tighten until 2035. Manufacturers exceeding their average fleet emission targets must pay a penalty. The...

To counter the threat of deindustrialization due to soaring energy prices and facilitate a green transition, policymakers have devised new subsidy schemes such as the "bridge electricity price" (BEP). To analyze this, we develop a model, where the principal introduces a subsidy program to...

We analyze the equilibrium effects of different subsidies on target goods under both perfectly competitive and monopolistic market structures. We concentrate our analysis on three particularly common forms of subsidies: (i) a per-unit subsidy, (ii) an ad valorem subsidy, and (iii) an "inversely...

Katz (1987), DeGraba (1990), and Yoshida (2000) have formulated theories that price discrimination bans in intermediary goods markets tend to have positive effects on allocative, dynamic and productive efficiency, respectively. We show that none of these results is robust vis-à-vis endogenous...

We analyze the effects of structural remedies on merger activity in a Cournot oligopoly when the Antitrust Agency (AA) cannot observe a proposed merger's efficiency type. Provided the AA follows a consumer surplus standard, an efficient merger type is doomed to over-fix with its divestiture...

We analyze the welfare effects of structural remedies on merger activity in a Cournot oligopoly if the antitrust agency applies a consumer surplus standard. We derive conditions such that otherwise price-increasing mergers become externality-free by the use of remedial divestitures. In this...

We re-examine the view that a ban on price discrimination in input markets is particularly desirable in the presence of buyer power. This argument crucially depends on an inverse relationship between downstream firms' profits and the uniform input price. Assuming different input efficiencies...
