“…quality and quantity of feed, health care and housing), which are likely to have occurred and contributed positively to the average milk yield of animals. In absence of information about possible changes in inputs and the costs related to such changes, conclusions on the impact of these trends in terms of costs and benefits and more generally in terms of the overall economic efficiency of the system ( Acosta and De los Santos-Montero, 2019 ) cannot be drawn. Karugia et al (2001) concluded that crossbreeding of cattle had a positive effect on the Kenyan economy and social welfare, although they speculated that the introduction of exotic genes may have not been beneficial at farm level, because improved animal productivity also involved accrued input costs.…”

Importation of livestock genetic resources from industrialized countries for introgression of specific traits and other forms of crossbreeding is often indicative of a shift in production systems toward greater intensification and specialization. In developing countries, imported genetic resources are regarded as both a solution to improve the performance of local livestock and as one of the main threats to local populations. Using international databases, censuses and technical reports, we investigate ongoing trends and consequences of these two phenomena in 40 countries from Africa, Asia and Latin America. In these countries, the share of locally adapted breeds within species has decreased by an average of 0.76% per year over the last 20 years. The corresponding increase has been distributed between pure exotic breeds and crossbred animals, with differences across regions. In several countries, increased utilization of exotic cattle breeds and crossbreeding has been accompanied by a trend in increased milk yield per cow. The shift from local genetic resources to crossbred and exotic animals must be considered in the context of challenges such as food security, erosion of agrobiodiversity, interactions with other agricultural production, reduction of poverty and provision of ecosystem services, as well as resilience to and mitigation of climate change.

“…This specification can be estimated through a multi-step procedure as in the work of Kumbhakar et al (2014) or through a more efficient simulated maximum likelihood estimation (MLE) method, as in the work of Filippini and Greene (2015) and Colombi et al (2014). The multi-step procedure involves easier computation and provides consistent estimates, which justify the extensive use in the literature (e.g., Agasisti and Gralka 2019;Acosta and Santos-Montero 2019), as is the case for this paper.…”

Transient and Persistent Efficiency and Spatial Spillovers: Evidence from the Portuguese Wine Industry

et al. 2021

This paper investigates the presence of spatial spillovers in firms’ productive (in)efficiency. For this purpose, a spatial stochastic frontier model is specified and estimated, accounting for spatial dependence and persistent and transient (in)efficiency. This approach is applied to a panel dataset from 2014 to 2019 of Portuguese wineries. Apart from the traditional input and output quantities used in the estimation of a production function, the novelty of this study is the inclusion of information on the firms’ exact location, which allows incorporating the neighboring dependence in the productive efficiency analysis. Empirical findings show that despite the Portuguese wineries’ technological positive dependence on spatial closeness for both inputs and outputs, the geographic closeness is not strong enough to provide overall productive efficiency gains.

“…For the first time, total factor energy efficiency will be defined and measured by distinguishing the components in stochastic frontier model, where individual effects are disentangled and long-and short-run inefficiencies are measured at the provincial level in China. The disparity between individual heterogeneity, long run efficiency, short run efficiency and disturbance term, which contributes to exact estimation and recognition of efficiency, has been specified within stochastic frontier model in recent years (Acosta and De los Santos-Montero, 2019;Musau et al, 2020), but lacks detailed empirical evidence on China. Here, individual effect is used as a different term from efficiency and reveal heterogeneity in characteristics between provinces.…”
