Consistent with the theory of storage, we find that positive inventory surprises move adjusted calendar spreads toward full financial carry (i.e., toward zero), whereas negative surprises make them more negative. Our results demonstrate that inventory news matters more when convenience yield is relatively high. In addition, we find that larger WASDE inventory surprises lead to greater volatility in calendar spreads. We also show that surprises generally move futures prices across the forward curve in the same direction, but nearby contracts respond more strongly than deferred contracts. Overall, our results confirm the value of WASDE reports and futures markets in efficiently allocating grain over time.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"12 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Options respond faster to new information, whereas futures contribute more to the efficient price shared by both markets. We provide a market microstructure explanation for this pattern. We find a 1 per cent increase in options’ relative aggressive quoting, defined as quotes that move the best bid or offer price, is associated with a 0.25 per cent increase in their relative speed of price adjustment and a 0.15 per cent decline in their relative contribution to the efficient price. By contrast, options’ relative trading volume is negatively associated with their speed advantage and is unrelated to their contribution to the efficient price. These findings highlight the distinct roles of quoting and trading in cross-market price discovery.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"42 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149150937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop a system dynamics model in which cyclical behaviour arises endogenously from biological delays and a simple adjustment rule, without the explicit modelling of price or forward-looking optimization from decision-makers. The model reproduces the cyclical component of Dutch pork prices, matching its wavelength and turning points, and explains the gradual shortening of the cycle through technological changes that reduced production lead times. Sensitivity analysis further separates the parameters that govern the cycle’s wavelength from those that govern its amplitude, and identifies policy levers acting on each. Our findings do not imply that prices are irrelevant; rather, they highlight that a significant part of the pork cycle is structural, with prices primarily reflecting underlying production delays. This perspective complements rational-expectations models and clarifies why similar ‘pork cycle’ patterns appear in other industries with long lead times.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"4 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper develops a new framework for measuring trade diversification based on Hill numbers, which capture both the extensive and intensive margin of trade connections. Using HS6-level bilateral data for 188 countries from 2000 to 2022, I first document global patterns of diversification and concentration across agri-food sectors. The descriptive evidence shows that most countries trade with many partners in principle, yet effectively rely on only a few, especially for grains and oilseeds. I then estimate the effect of import and export diversification on within-year food price volatility using a shift–share instrumental-variable design that exploits exogenous foreign sector-level shocks weighted by lagged bilateral trade exposure. The empirical results show that more balanced and diversified import portfolios are strongly associated with lower food price volatility, whereas export diversification plays a more limited role. Policies encouraging diversification can reduce food price volatility but involve trade-offs between efficiency from international specialization and resilience of the input–output network.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"22 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148922852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recycling process requires high energy inputs, thus the joint distribution of (input) energy and (output) fertilizer commodity prices is a crucial determinant of the profitability of investing.

Moreover, we show that standard approaches overestimate the variance of investment returns. Finally, we find that phosphorus recycling investments are only profitable with substantial subsidies or savings on disposal expenditures.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"35 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148894708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We develop a bargaining and search model with two mechanisms: information discovery, which reduces herders’ search costs, and information posting, which expands market access. Using household survey data, we find that smartphone adoption increases selling prices. Mechanism analysis shows that traditional phone functions improve information access, while smartphone-specific features, especially information posting, enhance bargaining power by expanding selling channels and trader access. These findings demonstrate that digital technologies affect market outcomes not only through improved information access but also by reshaping bargaining structures and market participation.","PeriodicalId":50476,"journal":{"name":"European Review of Agricultural Economics","volume":"32 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148894709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that carbon pricing reduces emissions, and higher price levels are associated with lower uncertainty in policy outcomes. While expected results remain similar to deterministic simulations, stochastic modeling reveals greater regional and sectoral heterogeneity.

Nevertheless, having a larger climate club imposing CBAM tariffs and applying exporters’ emission intensities are more effective in lowering global emissions.
