The same country, different experiences of safety. An evidence-led investigation of gender, past victimization, police visibility and the everyday choices people say they avoid.
Sixteen exhibits and two D3 instruments put electric-car adoption on the inspection floor. Follow Germany’s two clocks, draw a five-year path, compare sixty markets, and trace the long road from new sales to the existing fleet.
One integrated research article on AI and the boundary of the firm. Explore a clearly labeled make-or-buy teaching model, follow the financial and company evidence, and distinguish investment, control, production and responsibility.
Thirty-nine exhibits and three linked instruments compare the US, Canada and the EU. Follow the Rank Weave, inspect country relationships through time, and test how analytical weights move Canada across the Atlantic Seam.
Fourteen seconds and the making of the Moonwatch. Follow the record, inspect eleven qualification tests, compare precisely identified references, and explore a 3D watchmaker’s table.
A guided investigation into apparent choice, ownership and exposure across eight countries. Test how grouping, weighting and missing owner names change the answer.
Germany’s post-2018 disturbance average is 2.25 times its earlier rate, but 2024 is not a top-decile year in any of six countries. Ten exhibits separate forest land, canopy disturbance, recurrence and the limits of the map.
Germany and Estonia put PISA’s averages and social gaps in perspective. Twelve exhibits connect equality of opportunity, Rawls and Roemer, skill formation and the difference between AI-assisted work and independent learning.
The data-center boom is real. Fifteen exhibits separate national investment accounting, local construction outcomes and grid constraints from an unproven general housing squeeze.
Orders are one thing. Output is another. Thirty exhibits test Germany’s conditional production gap, energy exposure and capacity to execute, including the evidence against a single structural explanation.
Immigration totals can barely move while the arriving population changes profoundly. Follow the education shift and explore a world atlas of age, sex and qualifications from 1990 to 2020.
Open releases can compress the capability gap. A frozen Epoch frontier clock shows why the next closed release can open it again.
A closed Rhine bridge connects 28,845 commuting relationships to a harder question: what does an alternative route need to preserve?
Music, protest, and violence share a local geography. A county timeline and lag model show why that ecosystem should not be mistaken for a causal conveyor belt.
AI-exposed occupations were already highly paid. Germany does not yet show their wages pulling further ahead after ChatGPT.
Germany has more women than men overall—but among 18–29-year-olds there are only 912 women for every 1,000 men. A living atlas traces where the gap opens, crosses over, and widens by nationality.
AfD support rose across German districts. Working-age population retention—not aging by itself—is the strongest observed regional-capacity correlate; the political feedback loop remains unproven.
Europe’s child population is shrinking, but older recipients, premium mix and IP-enabled return loops have given the toy industry a demographic hedge.
Total Canadian airport screenings recovered above 2019, while U.S. transborder traffic fell behind domestic and non-U.S. international travel.
Employment stocks remain resilient while the flows into and between jobs weaken across five labour markets.
EU commercial flight movements recovered to 98% of 2019. European hub connectivity recovered to 88%. Frankfurt shows why frequency, seats, passengers, and connectivity need separate measures.
Across 831 U.S. occupations, relative AI exposure and projected labor demand resolve into different distributions.
Across 400 districts and 35 years, extreme heat shifted from an occasional disruption into a recurring operating condition.
Tychy’s estates reveal visible age and access differences, but a twenty-estate model cannot turn planning chronology into a causal effect.
Three city averages yield one ranking. But 74.6% of population-weighted midday surface-temperature variation lay inside the cities.
The age gradient in heat-associated presentations is strong. The evidence for an emergency-department throughput shock is not.
Production, exports, and factory-gate value reveal three different geographies of Europe’s ice-cream economy.
Kaub’s low-water shock is visible; a national nine-sector panel does not recover a stable industrial-output penalty.
Total manufacturing orders rose 3.1%, but broad orders and realized turnover moved in the opposite direction.
The June divergence between German manufacturing orders and production is real; a post-2021 structural break is not established.
The coefficient survives. Its meaning changes once convergence, capacity, and within-Land adjustment become visible.
What Germany’s regional aging ratio does and does not reveal about growth, convergence, productivity, and automation.
German chemicals and energy-intensive industry since 2010: what the gas shock caused, what it cannot explain, and why persistence changes the policy test.
Component reliability does not determine systemic safety. This second-revision manuscript derives a systemic-failure rate from dependence architecture, then composes it with welfare exposure and model ambiguity.
Tail pressure, dependence architecture, and why a falling catastrophe probability is reassuring only when it falls faster than welfare exposure grows.
A forensic BEA–BLS evidence audit corrects the apparent AI productivity gap, opens 61 industries to inspection, and traces where capability disappears before it becomes durable output.
Paul Romer, artificial intelligence, and the economics of validated knowledge: why growth depends on proof, absorption, and diffusion rather than candidate volume.
What Solow gets right about AI: capital, machine services, weak links, energy, adoption, productivity measurement, and the investment race.
Liu et al.'s NBER paper uses 175 years of data to show how technology shaped labor markets—and why AI may reverse every historical trend from education premia to gender convergence.
What train records reveal about Operation Reinhard: reconstructing the hyperintense 'pulse' of late-summer 1942 through rate-centric genocide analysis.
A deep dive into Fügener et al.'s groundbreaking research on automation versus augmentation—and the emergence of a tripartite workforce taxonomy.
How artificial intelligence reshapes the hierarchies of tacit knowledge—and the normative trade-offs between efficiency and equity in the emerging knowledge economy.
A research digest from November 2025: Structural rigidities and the macroeconomic consequences of the 'missed decade' in climate policy.
Generative AI as a Determinant of Labor Market Dynamics. New empirical evidence reveals a 13% employment decline for early-career workers in AI-exposed fields.
A comprehensive synthesis of late 2025 research from NBER, IMF, and OECD revealing a 'Great Fracture' in labor markets and industrial organization.
Why standard economic models fail when facing low-probability, high-impact events like climate change. A proposal for a new risk-adjusted discount rate.
A deep dive into empirical substitution elasticities for climate policy modeling. How flexible is production really?
A canonical research essay on decomposing Europe’s energy-intensity decline into technological and structural effects.
How Germany's feed-in tariff shaped the spatial equilibrium of wind investment (1996–2010) — and why grid integration becomes the hidden constraint.
An empirical investigation into co-authorship patterns in environmental economics. How the 'lone wolf' model of research gave way to team science.
How international trade affects environmental outcomes through scale, composition, and technique effects—evidence from European manufacturing.
A rigorous ethical examination of intergenerational discounting—why market-rate arguments fall short, and how impossibility results reshape what 'fair' evaluation can mean on infinite horizons.
A comprehensive survey of how exogenous and endogenous technological change has been incorporated into climate-energy-economics models—and why these assumptions fundamentally shape policy recommendations.
