Abstract:
MIRAGE is a multi-region, multi-sector computable general equilibrium (CGE) model, initially devoted to trade policy analysis and more recently applied to long-term growth and environmental issues. It incorporates energy, carbon pricing, imperfect competition, and rigid investment allocation, in a sequential dynamic setup where installed capital is assumed to be immobile. The model provides trade analysis with detailed treatment of trade costs and Armington specifications, drawing upon a detailed measure of trade barriers through the MAcMap-HS6 database. Production features nested CES functions with capital-energy bundles under both perfect and imperfect competition frameworks, while final demand follows a LES-CES utility function. The sequential dynamic framework enables longterm simulations by combining total factor productivity calibration with macroeconomic projections from the MaGE model. The most recent version offers significant improvements in electricity sector modeling with renewable energy representation, base-load and peak-load dinstinctions, and detailed greenhouse gas (GHG) emissions accounting with carbon market mechanisms. This documentation provides complete technical specifications, calibration procedures, and implementation guidelines for researchers and policymakers using MIRAGE for economic policy analysis.

12. Taking Stock of Brexit

Author:

Publication Date:

Content Type:
Policy Brief
Institution:
LSE IDEAS
Abstract:
J ohn Curtice, the UK’s foremost polling expert, wrote recently that ‘politicians do not talk much about Brexit these days’ (Curtice, 2025). In Germany, too, Brexit has largely disappeared from view, according to a prominent journalist consulted in the preparation of this blog. Another expert, Anand Menon, told AP News on the fifth anniversary of the UK leaving the EU that Brexit had ‘changed our economy’, adding that ‘our politics has been changed quite fundamentally’ (Lawless, 2025). His view is that, in electoral politics, conventional political cleavages have been supplanted by ‘a new division around Brexit’ (Lawless, 2025). In much of the EU, the 2025 anniversary elicited many articles characterised by a combination of acknowledgment that Brexit had failed to deliver, resignation about the UK’s fate and a sense of growing disinterest. The Austrian newspaper Kourier summed up these sentiments: “Von skurril bis tragisch: Eine Bilanz nach fünf Jahren Brexit [From bizarre to tragic, a stocktake after five years of Brexit]” (Bauer, 2025). However, Brexit is a process, rather than a discrete event, and some of its effects are both contested and take time, and are often seen through ideological rather than analytic lenses. A useful way to assess its consequences is to distinguish between three key dimensions: economic, social and governance related. The overall economic effects of Brexit have mainly been negative on both sides of the English Channel, albeit uneven, although some critics regard the magnitudes as having been exaggerated.

14. The Ukraine War Prospect: How Peace Plans Might Work and Why They Will Fail

Author:

Content Type:
Working Paper
Institution:
Project on Defense Alternatives
Abstract:
During 2025 multiple contending Ukraine peace and cease-fire proposals were put forward by the Trump administration and America’s European partners. This article examines how the leading official proposals fell short. And it presents two, simpler proposals better aligned with battlefield realities. The article also explores the evolution of US, Ukrainian, Russian, and West European public opinion on the war. The Russia-Ukraine war has been a disaster – not only for the two principal combatants, who together have suffered 300,000 deaths, but for the entire world. This fact drives the imperative to end this conflict forthwith via negotiated compromise. Yet, as the article shows, none of the official proposals embrace this imperative. Instead, all exhibit efforts to win advantage for one side or the other. They are instances of diplo-fare – war by means of diplomacy. As such, their aim may be rejection not agreement, with an eye toward painting one’s opponent as intransigent and, in this way, build support for continuing the fight – or, in the case of President Trump’s preference, establish a pretext for US withdrawal. The simplest proposals may be the most practicable but these must reflect current battlefield realities rather than attempting to “correct” or “re-balance” them. This principle guides the independent cease-fire options suggested in this article. Otherwise, the article explores the possibility that Europe’s so-called Coalition of the Willing will respond to any serious fracture of Kyiv’s effort – a distinct possibility – by establishing a new nuclearized Europe-vs-Russia “central front” inside Ukraine. (With an Appendix summarizing the official November and December peace proposal texts.)

15. Variables of War

Author:
Lutz Unterseher
Publication Date:

Content Type:
Working Paper
Institution:
Project on Defense Alternatives
Abstract:
This essay argues that wars do not result from immutable human nature but from political motives, cultural dispositions, and calculations of military opportunity. Wars are, therefore, preventable. The essay presents a succinct causal model of war’s outbreak. ​ The formal causal argument: War’s outbreak is treated as the dependent variable; the independent variable is a mix of expansionist or preventive motives and a supportive war culture that glorifies offensive action and soldierly virtues (the “cult of the offensive”).​ Because such motives and cultures often do not lead to war, a further “sufficient condition” is posited: leaders must judge that a rapid victory is feasible, casualties acceptable, and domestic opposition manageable, typically by identifying structural vulnerabilities or “open flanks” in the opponent’s posture.​ This feasibility variable is an intermediate link between motives/culture and war and is filtered through perceptions often distorted by ideology, institutional dysfunction, or poor intelligence.

16. After Ukraine: Prospects for a Russian Resurgence in the Middle East

Author:

Publication Date:

Content Type:
Special Report
Institution:
The Washington Institute for Near East Policy
Abstract:
Moscow has cultivated ties with U.S. adversaries and allies alike, and Washington must respond by advancing a holistic policy that empowers Ukrainian commercial interests and addresses deficits in sanctions policy. Russia’s position in the Middle East has faced major setbacks in recent years, including the fall of Syrian dictator Bashar al-Assad, the weakening of Iran and its proxies, and the toll from Moscow's unending war of choice in Ukraine. But reports of a Russian retreat from the region are premature. Alongside traditional defense and economic relationships with Algeria, Egypt, and Iraq, Moscow has cultivated ties with a host of other countries—U.S. adversaries and allies alike. With Iran, it has reportedly begun assembling Su-35 fighters as part of a $6.5 billion deal that would boost the regime’s air force. With the United Arab Emirates, an American ally, Russia’s non-oil trade grew to $11.5 billion as of 2024. And in Syria, Russia’s pre-revolution military bases remain in place, while an October meeting between Presidents Putin and Sharaa indicated a cooperative spirit. In this comprehensive Policy Note, experts Anna Borshchevskaya and Matt Tavares argue that Russia is poised for a resurgence in the Middle East, especially once the war in Ukraine ends—a point they also make clear in a hard-hitting op-ed published in the National Interest. Washington, they argue, must recognize the multiple threats this would present to U.S. interests in the region and develop a vigorous counterstrategy in response—one that includes empowering Ukrainian commercial interests, refining sanctions policy, and rebutting Russian propaganda in real-time.

17. Pakistan Steps In: Sudan and the Transformation of Regional Security

Abstract:
A $1.5 billion Pakistani arms deal with Sudan signals a regional shift from diplomacy toward military escalation, which may prolong the war in Sudan. At a moment that should have seen renewed momentum toward a political settlement in Sudan, reports suggest that Pakistan, with Saudi mediation, is nearing completion of a $1.5 billion arms deal with the war-torn country. Far from being a routine arms transaction, the deal encompasses Karakoram-8 aircraft, more than 200 drones, and air defense systems. It also potentially includes JF-17 multirole fighter jets, produced jointly by Pakistan Aeronautical Complex and China’s Chengdu Aircraft Corporation. This development points to a deeper regional shift away from sponsoring dialogue and toward a military resolution to the Sudanese conflict.

19. Russia Leverages Venezuela to Expand Influence in Western Hemisphere

Working Paper
Institution:
The Jamestown Foundation
Abstract:
Moscow has condemned the U.S. capture of Venezuelan President Nicolas Maduro while avoiding substantive retaliation, demonstrating both symbolic solidarity and an unwillingness to jeopardize relations with Washington. The Kremlin’s relationship with Venezuela enables Moscow to project power beyond Cuba in the Western Hemisphere, access Venezuela’s oil reserves, and cultivate an alliance aligned with an anti-Western agenda. Russian energy firms have gained oil stakes and repayment-in-kind options for investments in Venezuela, while joint financial ventures and Venezuela’s crypto experiments have served as testing grounds for sanctions-evasion mechanisms later adapted by Russia. Arms transfers, military-industrial collaboration, and media partnerships through RT, Sputnik, and TeleSur expanded Russia’s military footprint and narrative reach in the Western Hemisphere, though the financial return on Russian investments remains limited and challenged by U.S. pushback.

20. Russia–Azerbaijan Relations Remain in State of Limbo

Content Type:
Working Paper

The Jamestown Foundation
Abstract:
Azerbaijani President Ilham Aliyev’s decision to skip Commonwealth of Independent States (CIS) and Eurasian Economic Council meetings in December 2025 signaled renewed strain with Moscow, surprising observers who believed the October 2025 Dushanbe summit had stabilized relations after the December 2024 Azerbaijan Airlines (AZAL) crash. Tensions resurfaced after Azerbaijan learned Russia had closed the crash’s criminal investigation, which contradicted Russian President Vladimir Putin’s Dushanbe assurances of missile-related responsibility, legal accountability, and compensation, instead attributing the crash to weather and pilot error. Conflicting Russian narratives and public criticism in Azerbaijan highlight a widening gap between Moscow’s political statements and legal actions, leaving normalization stalled and Russia–Azerbaijan relations suspended in distrust rather than reconciliation.
