Converting to organic farming in France: Is there a selection problem? AgEcon
Latruffe, Laure; Nauges, Celine.
Using a sample of French crop farms during the 1999-2006 period, we test whether less technically efficient farmers are more likely to engage in organic farming in order to benefit from conversion subsidies. Despite some limitations in our data, we find no evidence of such selection effect. On the contrary, our estimation results indicate that more technically efficient farmers are more likely to convert to organic farming. This finding is found to be robust to the method of calculation of efficiency scores, either parametric or non-parametric. This study also confirms that farm’s characteristics (education, farm size and legal status) and farmers’ practices under conventional farming do impact the probability of conversion to OF.

Environmental and production cost impacts of no-till: Estimates from observed behaviour AgEcon
Laukkanen, Marita; Nauges, Celine.
No-till has been promoted as a cultivation method that reduces both production costs and the environmental impacts of farming relative to conventional tillage. Using farm-level data from Finland, we show that no-till has no statistically significant effect on total variable costs but that it increases the use of plant protection products and fertilizers, and decreases the use of labor. An environmental impact simulation combining the results on input use with a nutrient and herbicide runoff model predicts that no-till produces environmental benefits on highly erodible land, but may be even detrimental to the environment in average conditions.

Food Safety Regulation and Firm Productivity: Evidence from the French Food Industry AgEcon
Requillart, Vincent; Nauges, Celine; Simioni, Michel; Bontemps, Christophe.
The purpose of this article is to assess whether food safety regulations imposed by the European Union in the 2000s may have induced a slow-down in the productivity of firms in the food processing sector. The impact of regulations on costs and productivity has seldom been studied. This article contributes to the literature by measuring productivity change using a panel of French food processing firms for the years 1996 to 2006. To do so, we develop an original iterative testing procedure based on the comparison of the distribution of efficiency scores of a set of firms. Our results confirm that productivity decreased in the poultry processing industry at the time when safety regulation was reinforced.

Heterogeneous Responses to Water Conservation Programs: The Case of Residential Users in Los Angeles AgEcon
Hanemann, W. Michael; Nauges, Celine.
We propose a detailed analysis of heterogeneity in households’ responses to water conservation programs (price increase, voluntary and mandatory conservation) during periods of water shortage. Using a unique dataset covering water consumption of all residential users in Los Angeles (California) during the drought (1988-1992), we show that households generally were responsive to the conservation measures but that the magnitude of households’ responses varies depending on the instrument and on households’ characteristics, in particular the size of their lot. Price elasticity is estimated between –0.29 and –0.47 in the high season (June-October), and between 0 and –0.19 in the low season (November-May). Results suggest that the voluntary conservation program...

Identifying the Effect of Unobserved Quality and Expert Reviews in the Pricing of Experience Goods: Empirical Application on Bordeaux Wine AgEcon
Dubois, Pierre; Nauges, Celine.
We propose a structural empirical approach à la Levinsohn and Petrin (2003) to disentangle the effect of experts’ grades from the effect of unobserved quality on the pricing of experience goods. Using a panel data set of 108 châteaux selling wine on the Bordeaux ‘en primeur’ market, we provide some empirical validation for the theoretical result that the price set by wine producers is used as a signal for wine quality. We confirm that experts’ grades affect producers’ choice of ‘en primeur’ price above the effect of unobserved wine quality. Our empirical results also show that failing to control for endogeneity caused by the omission of unobserved leads to over-estimate the influence of experts’ grades on the ‘en primeur’ price.

On Production Function Estimation with Selectivity and Risk Considerations AgEcon
Koundouri, Phoebe; Nauges, Celine.
In the estimation of production functions, ignoring risk considerations can cause inefficient estimates, while biased parameter estimates arise in the presence of sample selection. In the presence of uncertainty and selection bias, the latter introduced by the endogeneity of qualitative characteristics of inputs in crop choice, we show that correcting for risk considerations (a la Just and Pope, 1978, 1979) but not selection bias, can produce incorrect inferences in terms of risk behavior. The arguments raised in this study have estimation and policy implications for stochastic production analysis applied to all goods whose qualitative characteristics can affect sample selection.
