“…The estimated coefficient for cattle herd size is positive and significant at the 5 per cent level for beef farmers in the TB and JD models and in dairy farmer TB model; and 1 per cent level for dairy farmers in the JD model, indicating that the number of cattle on a farm would significantly influence willingness to pay for and use a subunit vaccine. This is consistent with the result of Ma et al () who found herd size to be positively and significantly influencing dairy production. The marginal effects suggest that increasing the herd by one unit increases beef and dairy farmers WTP for bTB subunit vaccines by 11 and 0.01 per cent, respectively, and 0.01 and 0.1 per cent for JD subunit vaccine.…”

The willingness to pay (WTP) approach is increasingly being used in different disciplines to assess peoples' readiness to accept change. This paper assesses the potential for two subunit vaccines for the prevention and control of bovine tuberculosis and paratuberculosis in cattle. A survey of beef and dairy farmers was conducted across Canada to identify factors that influence their WTP for subunit vaccines. Estimated results of the interval-data model indicate that the size of a farmer's cattle herd, neighbourhood effect, and buyer recommendations for vaccination significantly influence farmers' WTP while veterinarians appear to be the most critical pathway for farmers to source information on new vaccine options. The mean willingness to pay amounts for both vaccines reveals that farmers are likely to use the vaccines if the costs are kept at reasonable level.2 Companion diagnostics reveal the presence of the disease-causing organism in an infected animal but do not show a positive response in vaccinated animals. Therefore, it can differentiate between vaccinated and infected animals, especially for bTB and JD. 3 www.ifst.org/sites/default/files/Livestock%20Vaccines-PN-433_0.pdf 4 Ibid.

“…The results of these researches on effectiveness were quite diverse, which was related to the assumptions made in the models (Mareth et al, 2016;Minviel and De Witte, 2017;Minviel and Latruffe, 2017;Špička and Smutka, 2014;Rusielik and Świtłyk, 2012). The results of the analyses prove that efficiency is related to the amount of expenditure per unit of production (Michaličková et al, 2013), with farm size and production intensity (Jiang and Sharp, 2015;Ma et al, 2019). Research also indicates a link between farm efficiency and milk quality (Kelly et al, 2013) and animal welfare (Allendorf and Wettemann, 2015).…”

Abstarct:Purpose: The main objective of this article was to determine the technical efficiency of Polish dairy farms in 2008-2017, taking into account the dependence on the herd size, the milk yield of cows and the effects of scale. Design/Methodology/Approach: The non-parametric DEA method based on the concept of border efficiency was used to assess technical efficiency. The research uses models assuming constant (CCR) and variable returns to scale (BCC). The source of the data was information collected by the Farm Accountancy Data Network (FADN) in Poland. Data came from farms specializing dairying (type 45), with more than 15 cows. Findings: The results of the conducted research indicate a higher share of efficient farms using the model assuming variable returns to scale. The average efficiency ratio increased along with the increase in the size of the herd of cows and the improvement in the milk yields of cows. Practical Implications: The results of this study will be used to determine rationally the combination of inputs in dairy production. The result of these activities is an increase of efficiency and the use of economies of scale. The article clearly presents among which farm groups exists the lowest efficiency (cow herd size and milk yield). Originality/Value: The study fills a gap in approach methods to conducting research on dairy farm efficiency. On the one hand, the value of the article is built by the size of observation field, on the otherdairy farms classification by cow herd size and milk yield.

“…Productivity This article adopts stochastic frontier analysis (SFA) to estimate technical efficiency, which has been used in some studies (e.g., Jin et al 2010 , Wang et al 2016 , Ma et al 2019 , and Gong and Sickles 2020 ) to measure the productivity gap. It is worth noting that the DEA also has its own advantages, as it does not need to impose assumptions of parametric functional forms and distributional assumptions on random noise and inefficiency as in the SFA.…”

World agricultural convergence

et al. 2021

The goal of this article is to answer two questions: Has world agricultural convergence occurred? If not, how can this goal be fulfilled? This article introduces a model averaging method to consider both a parametric and a semi-parametric SFA model to better estimate technical efficiency. Then, three types of convergence tests are employed to check if world agricultural catch-up occurs and to determine the degree of convergence across different groups of countries. The empirical results on a balanced panel of 126 countries from 1970–2014 show that world agricultural convergence has not occurred. This article then investigates the situations in different groups of countries and discusses how to use international trade, irrigation system, and structural transformation to improve agricultural efficiency and to diminish the efficiency gap among different countries in the future.
