Price discovery and long-distance market integration: Evidence from the Republican Chinese Cotton Goods Exchange
Dear Julien Brault — this week’s five most relevant discoveries, curated for your work in Economics.
Key findings
Economics · Economic History
No. 1
The study uses a Republican-era Chinese cotton goods exchange to examine how prices formed across spatially separated markets and what that implies for long-distance integration. Its evidence is drawn from an exchange setting in which trading relationships connected distant markets, allowing price discovery to be analysed as an institutional and spatial phenomenon. For an economic historian of French postwar exchange controls and oil quotas, this provides a comparative frame for asking how administrative and market mechanisms jointly shaped price integration.

Patently peculiar: Patents and innovation in the United Kingdom of the Netherlands
The patent system of the United Kingdom of the Netherlands between 1815 and 1830 formally distinguished patents of invention from patents of importation, protecting both domestic inventions and the introduction of foreign technologies. Using a hand-collected dataset covering all applications, the authors show that administrators systematically differentiated between the two patent types in ways consistent with a technology policy encouraging domestic introduction of useful foreign technologies, while decisions reflected novelty, utility, and applicant characteristics without evidence of systematic discrimination. For a scholar of French postwar planning, this offers a historical benchmark for how discretionary administration can combine accessibility, screening, and technology transfer during industrialization.

Looking Under the Hood of Commodity Currency Predictability
The article investigates predictability in commodity currencies, with its framing pointing toward the mechanisms that generate forecastability rather than surface-level predictive performance alone. Published in Management Science as an ahead-of-print article, it belongs to the intersection of international finance, commodity-price exposure, and predictive modelling. For a researcher of postwar exchange controls and oil import quotas, it offers a contemporary finance lens for connecting commodity-linked risk to currency analysis and investment evaluation.

Subsidy salience and the effectiveness of green policies
The paper examines green purchase subsidies when consumers are environmentally conscious but pay limited attention to subsidy salience. It studies how salience affects firms’ environmental product qualities, pollution levels, and subsidy pass-through, and it describes the optimal policy mix when the government can raise salience at a cost. For policy evaluation in institutional finance, this is directly relevant to assessing whether subsidy design and communication improve environmental outcomes or mainly alter the incidence of support.

Democracy Doesn’t Always Happen Over Night: Regime Change in Stages and Economic Growth
The paper argues that democratization is often not a discrete event but a two-stage process in which autocracies enter episodes of political liberalization that may or may not culminate in regime change. Using a repeated-treatment difference-in-differences design that captures nonparallel trends and selection into treatment, it finds stronger long-run growth effects than single-event models, while repeated episodes without regime change reduce growth in democracy and episode length does not. For applied policy evaluation and institutional analysis, this shows why the timing and sequence of reform—not just the final regime label—matter for estimating growth effects.
