The paper introduces a residual demand hypersurface to better measure market power in locational pricing markets, specifically by analyzing how output changes at one location impact prices across all locations. This model is applied to the Italian electricity market to explain supplier bidding behavior and the effects of generation capacity divestment.

The paper investigates the trade-offs farmers face between immediate agricultural yields and the long-term maintenance of soil biota. Using optimal control theory, it identifies six bioeconomic states based on ecological interactions (normal vs. nuisance), farmer expectations (sustainable vs. non-sustainable), and technical orientations (natural resource oriented vs. agricultural effort oriented). The analysis reveals that secure property rights and long-term preferences do not automatically lead to conservation; instead, their effect is ambiguous and depends on the specific bioeconomic state of the agroecosystem.

The authors argue that current WTO measures like the Producer Subsidy Equivalent (PSE) and Aggregate Measure of Support (AMS) are inadequate because they measure the volume of support rather than trade distortion. They propose a terms-of-trade indicator—the ratio of export price index to import price index—to identify unfair trade practices. The paper includes a taxonomy of subsidies and a two-country model to demonstrate how a deterioration in terms-of-trade (below a base of 100) can signal unjustifiable over-subsidization.

The author argues that mediation is not merely a tool for conflict resolution but a strategic foreign policy instrument that allows middle powers to create 'extra political power space'. By engaging in mediation, these states can build stronger Best Alternatives to a Negotiated Agreement (BATNA), create issue linkages for 'logrolling' with senior allies, and establish network ties. The paper illustrates this through an analysis of Turkey's mediation efforts under the AK Party government between 2002 and 2011, suggesting that Turkey leveraged its role as a peace broker to secure alliance benefits from the US and consolidate domestic political power.
