Dynamic stochastic analysis of the farm subsidy-efficiency link: evidence from France

Abstract

The existing literature on the subsidy-efficiency nexus is almost exclusively based on static modelling and thus ignores the inter-temporal nature of production decisions. The present paper contributes to this literature by developing a dynamic stochastic frontier model, which is then estimated using a sample of French farms over the period 1992-2011. For comparison purposes, the static counterpart of the dynamic model is also estimated. The results indicate that, in the dynamic case as well as in the static one, public subsidies are negatively associated with farm technical efficiency. Nevertheless, these linkages are found to be weak, and they are much weaker when dynamic aspects are taken into account.

The Role of Technical Efficiency Achieving Sustainable Development: A Dynamic Analysis of Norwegian Dairy Farms

“…There is no consensus in the economics literature on the relationship between debt and technical efficiency. For instance, earlier results obtained by [23] support our finding; however, [25] reported a positive correlation between technical efficiency and debt-to-asset ratio.…”

“…The datasets contain observations with zero values for investments. Thus, to use a flexible functional form (Translog), following the literature (see, for instance, [25,34] we transformed the value; that is, ln (I + I 2 + I) . All values are adjusted to 2015 values.…”

“…We can find in the literature both parametric and non-parametric dynamic approaches. Both kinds of approaches have pros and cons with respect to conducting dynamic efficiency measurement (see for a detailed review [4,25]). This study focuses on the parametric dynamic approach.…”

Dynamic Inefficiency and Spatial Spillovers in Dutch Dairy Farming

“…,Zhu et al (2012),Minviel and Sipil€ ainen (2018) andSkevas et al (2018b) who report a positive effect on inefficiency as a result of the income effect nature of subsidies that lowers farmers' motivation to work efficiently.…”

Endogenous dynamic efficiency in the intertemporal optimization models of firm behavior

“…is to estimate technical efficiency from Silva & Oude Lansink's (2013) dynamic directional distance function (oriented in the space of freely-varying inputs and investments into quasi-fixed dynamic factors) under its duality to the optimal current value function associated with the firm's intertemporal cost-minimization problem under the Hamilton-Jacobi-Bellman conditions (e.g., Serra et al, 2011;Kapelko et al, 2014;Oude Lansink et al, 2015;Kapelko, Oude Lansink & Stefanou, 2016, 2017Minviel & Sipiläinen, 2018). Thus, in practice, the strategy for a (primal) estimation of dynamic technical efficiency is effectively the same as that for the estimation of a more conventional static efficiency except that in the former case a distance to the frontier is measured in the space of variable inputs and investments as opposed to merely conditioning the distance function on quasi-fixed levels of dynamic inputs.…”
