{"title":"Bundling Genetic and Financial Technologies for More Resilient and Productive Small-Scale Farmers in Africa","authors":"Stephen R Boucher, Michael R Carter, Jon Einar Flatnes, Travis J Lybbert, Jonathan G Malacarne, Paswel P Mareyna, Laura A Paul","doi":"10.1093/ej/ueae012","DOIUrl":"https://doi.org/10.1093/ej/ueae012","url":null,"abstract":"Using a multi-year, spatially-diversified randomised controlled trial spanning two African countries, this paper explores whether a complementary bundle of genetic and financial technologies can boost the resilience and productivity of small-scale farmers. The analysis shows that both moderate droughts and more severe yield losses undermine the resilience of control group households, and that these shocks have long-lasting effects as farmers invest and produce less following shocks. Severe yield shocks also increase hunger and food insecurity. The genetic technology—drought tolerant seeds—provides economically significant protection against mid-season drought and mitigates the long-term drop in farm productivity seen in the control group. The financial technology—satellite-based index insurance—offsets the long-term consequences of severe yield losses that are not mitigated by the drought tolerant seeds. Finally, the analysis shows that treatment group farmers who experienced shocks and saw the technologies in action subsequently increased their agricultural investment beyond pre-shock levels, an effect we call the resilience dividend. Unfortunately, this apparent experiential learning cuts both ways. Farmers who did not experience the efficacy of the risk management technologies backed away from using them. Our findings thus showcase how genetic and financial risk mitigating technologies can offer farmers more complete protection, as well as the challenge of inducing sustained uptake of technologies that are midway between experience and credence goods and only infrequently reveal their benefits.","PeriodicalId":501319,"journal":{"name":"The Economic Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139910636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relying on newly developed balance sheet panel data from every non-financial Russian corporation (more than 2500 of them) between 1899 and 1914, we examine the characteristics of entering and exiting corporations, how new entrants evolved and the impact of founder identity on subsequent outcomes. Russian corporations evolved within a market environment, conditional on overcoming distortionary institutional barriers to entry that slowed the emergence of these leading firms in the Imperial economy.","PeriodicalId":501319,"journal":{"name":"The Economic Journal","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139759777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consistent with a mechanism of greater distrust in the government, formerly annexed areas are more likely to vote against laws suppressing dissent and report lower political trust.

This has structural implications for the relationship between inflation and unemployment, the price Phillips Curve (PC). Using data from the European Monetary Union (EMU) and exploiting the fact that job polarisation accelerates during recessions, we obtain two empirical results. First, countries experiencing a bigger shift in the occupational structure during a downturn exhibit a flatter PC afterwards. Second, the occupational shifts experienced during the Great Recession and the Sovereign Debt Crisis explain more than a fourth of the flattening of the curve in the 2002-2018 period. Then, using a New Keynesian model with unemployment and search and matching frictions, we highlight a channel through which labour market characteristics operate on the slope of the PC. Increasing labour market fluidity –i.e., higher separation and hiring rate– decreases the slope of the PC. Using micro-data, we find that in the EMU non-routine jobs are more fluid. We conclude that job polarisation flattened the PC.","PeriodicalId":501319,"journal":{"name":"The Economic Journal","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139648687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is used to study how retail distribution affects manufacturing and consumers. As the cost of distribution falls, the retail sector increases assortment size and allows a larger mass of manufacturers to enter, allowing consumers to buy more variety. Entry primitives in manufacturing and retailing determine vertical pricing power. The equilibrium of the model predicts the national retail sector is a fraction of the total economy that depends on the demand for variety. It is not affected by, e.g., consumer transportation cost or income. Data support this prediction.","PeriodicalId":501319,"journal":{"name":"The Economic Journal","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139648697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
