{"title":"The impact of agricultural minimum wages on worker flows in South Africa","authors":"Marlies Piek, Dieter von Fintel, Johann Kirsten","doi":"10.1111/saje.12357","DOIUrl":"https://doi.org/10.1111/saje.12357","url":null,"abstract":"Abstract This paper is the first to provide estimates of how minimum wages affect worker flows and employment growth rates in an employment scarce developing country context. We investigate the effects of a large, exogenous increase in agricultural minimum wages in South Africa. We find that changes occurred primarily among non‐seasonal workers. Non‐seasonal agricultural employment growth decreased in the initial periods after the minimum wage hike. This was mainly driven by slower rates of entry. The effect on the rate of entry decreases over time. While farms also responded by shedding non‐seasonal workers at higher rates, this negative effect was limited to 1 year directly after the minimum wage hike. Employment growth recovers 4 years after the policy shock, indicating that firms adjusted relatively quickly despite the large legislated minimum wage increase. Seasonal employment growth and rates of entry and exit of seasonal workers were for the most part unaffected. Descriptive statistics, however, suggest a slight compositional change among seasonal workers: Farms replaced the worst paid seasonal workers with other low‐income workers who were slightly better paid and presumably more productive.","PeriodicalId":46929,"journal":{"name":"SOUTH AFRICAN JOURNAL OF ECONOMICS","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136071182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observe a 40% decline in active employment between February and April 2020, half of which was composed of job terminations rather than furloughs. Initially, vulnerable groups were disproportionately affected by the labour market shock. Exploiting the dataset's panel dimension and comparing lockdown incomes of job losers to reweighted job retainers, we estimate that approximately 15%–35% of job losers fell into poverty in April. We find evidence of a limited recovery in the labour market and a decrease in poverty by June, in part attributable to expanded emergency social assistance.","PeriodicalId":46929,"journal":{"name":"SOUTH AFRICAN JOURNAL OF ECONOMICS","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46461313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By moving from price‐taking conditions to markets featuring markup heterogeneity for product varieties, the paper finds amplification of production inefficiency from −3.61% to −11.41% and amplification of total factor reallocation from 0.15% to 8.91%. The productivity results are robust to structural variations in the demand function, firm scale adjustment and firm growth. Similarly, input reallocation is robust to variation in demand structure and plant expansion. Furthermore, reallocation under common markups among all firms is robust to reallocation under heterogeneous markups among larger firms. Alternatively, large firms face demand inelasticities and charge higher markups thereby mimicking the behaviour of the survey of all firms. Under autarky, small unproductive plants charge higher markups than their small efficient counterparts. Demand elasticity increases (decreases) with industry output for smaller (larger) plants. Finally, a unit increase in capital intensity for resource‐constrained plants raises labour distortions and reduces capital distortions while reducing capital distortions for resource‐unconstrained firms.","PeriodicalId":46929,"journal":{"name":"SOUTH AFRICAN JOURNAL OF ECONOMICS","volume":"1 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41842709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a cross‐section analysis with data from the Demographic and Health Surveys (DHS) and a measure that captures variation in the terrains of the countries, we find that the more difficult it is to traverse the terrain in Burundi, Cameroon and Nigeria, the higher the likelihood of child stunting. However, this association is not consistent for Ethiopia until we account for the Oromia region, which has the capital city Addis Ababa. These results remain robust with the inclusion of socio‐economic factors related to child health (e.g. maternal health, maternal education and household income), demographic factors (e.g. gender of child), other geographical factors (e.g. rainfall patterns and malaria prevalence) and survey and region effects. The results suggest that there are complementary factors to geography that may contribute to poor child health outcomes, such as the quality of infrastructure and the ability to access healthcare services. Given that child health is a key development outcome, understanding such spatial variations associated with child health inequalities can assist in designing effective intervention programmes and allocating resources where they are most needed.","PeriodicalId":46929,"journal":{"name":"SOUTH AFRICAN JOURNAL OF ECONOMICS","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46407766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, how are terrorism and uncertainty impacting on economic complexity in Africa? Second, how are governance institutions moderating the effects of terrorism and uncertainty on economic complexity in Africa? To answer these questions, the study employed pooled ordinary least squares and dynamic system generalized method of moments (GMM) estimators, with a panel of 33 African countries over the period 2010–2021. We find that the unconditional effects of terrorism and uncertainty on economic complexity in Africa are predominantly negative and significant. We also find that governance institutions predominantly have unconditional positive and significant impact on economic complexity in Africa but failed to moderate the adverse effect of uncertainty on economic complexity. However, trade openness, international tourism and lagged economic complexity are potent factors promoting economic complexity in Africa, while physical capital stock remained a deterring factor. The study concluded that policymakers and leaders in Africa should engage in collaborative efforts at the African Union level to promote high‐quality institutions, while simultaneously addressing the detrimental effects of terrorism and uncertainty on the continent.","PeriodicalId":46929,"journal":{"name":"SOUTH AFRICAN JOURNAL OF ECONOMICS","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49051930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
