This paper determines the demand for a forestry program amongst rural households in western Kenya. It is based on a field survey with 277 households, using a stratified random sampling approach. The study follows attribute based method to elicit farmers’ preferences. Demand is measured in terms of additional number of trees that a household is willing to plant under different price schedules, including direct economic incentive to plant new seedlings. The mean willingness to plant new trees per household increases from 44 trees when farmers have to pay 10ksh/seedling, to 244 trees when farmers receive a payment of 10ksh/seedling. The paper uses fixed effects, random effects and random effect tobit models to estimate relevant parameters. Hausman...

Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers while adding value for feeder cattle buyers. However, questions remain regarding the economic costs and returns of such programs. A model was estimated with data from three consecutive-day sales, to determine the value that buyers place on preconditioning programs and related feeder cattle traits. Our results indicate that price premiums, although evident, appear to be insufficient by themselves to cover the marginal costs of preconditioning.

The Persistence of Poverty in Rural China: Applying an Ordered Probit and a Hazard Approach

Glauben, Thomas; Herzfeld, Thomas; Wang, Xiaobing.

The present study investigates the analysis of poverty persistence of Chinese farm households in the well-off Zhejiang province in the southeast. We firstly apply an ordered probit model examining household, farm, and regional characteristics affecting the probability that households are chronically poor. In addition, we apply a hazard approach to identify the risk of falling into and climbing out of poverty. Results indicate that there are increasing chances to climb out of poverty over time, and that the risk of falling into poverty seems to decrease after the household spent some time outside poverty.

The objectives of this paper are to study the impact of liberalisation on trade deficits and current accounts of developing countries. It is expected that trade liberalisation would promote economic growth from the supply side by leading to a more efficient use of resources, by encouraging competition, and by increasing the flow of ideas and knowledge across national boundaries. Trade liberalisation could lead to faster import growth than export growth and hence the supply side benefits may be offset by the unsustainable balance of payments position. This study uses panel data of 42 countries (both time-series and cross-section dimension) to estimate the effect of trade liberalisation and growth on trade balance while controlling for other factors such as...

We investigate the relationships between water quality and socioeconomic factors in California at the county level for the years 1993 to 2006 using 24 water quality indicators coming from seven different types of water bodies. We estimate these relationships using three classes of models: the traditional per capita income-pollution level - Environmental Kuznets Curve (EKC) - specifications, a more inclusive model containing main socioeconomic variables such as agricultural intensity, land use, ethnic composition, population density and educational attainment, and a model that includes the socioeconomic variables while accounting for spatial correlations too. For most water quality indicators, we do not find support for EKC specifications. For pollutants...

Complexities associated with the management of common pool resources (CPR) threaten governance at some marine protected areas (MPA). In this paper, using economic experimental games (EEG), we investigate the effects of both external regulation and the complementarities between internal regulation and non-coercive authority intervention—what we call co-management—on fishermen’s extraction decisions. We perform EEG with fishermen inhabiting the influence zone of an MPA in the Colombian Caribbean. The results show that co- management exhibits the best results, both in terms of resource sustainability and reduction in extraction, highlighting the importance of strategies that recognize communities as key actors in the decision-making process for the...

Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread...

After controlling a variety of feeder cattle characteristics and market and sale conditions in Iowa feeder auctions, the price premiums for preconditioning claims (vaccinations and minimum 30 days of weaning) with and without third-party certification (TPC) are estimated as $6.12/cwt and $3.35/cwt, respectively. These premiums differ statistically (p<0.0001), and their difference exceeds the average participation cost of TPC ($1/cwt). This indicates that TPC is valued in the market to credibly signal preconditioning investment under asymmetric information.

EU policy reform simulation based on panel data estimation of on- and off-farm labour supply equations for Dutch dairy farmers

Ooms, Daan L.; Hall, Alastair R..

This research focuses on the estimation of labour supply equations for Dutch dairy farmers that are suitable for policy simulations. Data availability leads to the fact that we can not estimate structural labour supply equations. We show how to derive reduced form equations suitable for policy simulations. In this research we use the panel data sample selection estimation approach of Kyriazidou (1997) and Wooldridge (1995) to estimate the off-farm labour supply equation. The two lead to different estimation results and different simulation results based on these.

The impact of fanya juu bunds on productivity in a high rainfall area in the Ethiopian highlands is analyzed based on data from a cross section household survey with multiple plot observations per household. The results from parametric and non-parametric analysis indicated that productivity from conserved plots was lower than from non-conserved plots. The Oaxaca-Blinder productivity decomposition results showed that there was little difference in plot characteristics between conserved and non-conserved plots, however the returns to those characteristics were higher for non-conserved plots. The sensitivity analysis, increasing fodder grass production on bunds, suggests that there are possibilities to make conserved plots as productive as non-conserved ones....

This paper aims at analysing the role of the environment in innovative strategies based on firm economic performance indicators such as employment, turnover, and labour productivity growth. We exploit a unique dataset of 773 Italian service firms with 20 or more employees comprising 1993-1995 CIS II data on firm innovation strategic motivations and 1995-1998 data on employment, turnover, and labour productivity from the System of the Enterprise Account (SEA). We specify a Gibrat-like empirical model in which the covariates include firm strategies (innovation and environmental), and a set of other explanatory variables and controls. Our econometric findings show a negative link between environmental motivations and growth in employment and turnover and a...

The article investigates the investment and financial constraints for French, Hungarian and Slovenian farms using FADN panel data with different econometric estimation approaches. Farm gross investment is positively associated with real sales growth and cash flow implying the absence of soft budget constraint. Gross farm investment is positively associated with investment subsidies. Specific results by country are found depending on farm indebtedness. Investment subsidies can mitigate some capital market imperfections in short-term, while on long-term what is crucial is farm sale ability to successfully compete in the output market gaining sufficient cash flow for farm competitive survival and investment.

We estimated dynamic panel models for the agri-food trade of six new Member States (the Czech Republic, Latvia, Lithuania, Romania, Slovakia and Slovenia) with selected countries and trade groupings between 1996 and 2005. In general, we found low income elasticities and high price elasticities of import demand for agricultural commodities. The lagged values for trade are highly significant. We also show that accession to the EU increased the new Member States' exports, but had less impact on their imports. The new Member States have gained significantly from liberalised access to the EU agri-food markets.

We examine the affect of retail and manufacturer coupons on the nutritional quality of breakfast cereal purchases made by households. Using household level purchase data we find that coupon usage has a significant impact on the nutritional quality of cereals purchased by households. Specifically, we find that the average sugar content decreases and the fiber content increases. This suggests that coupons have a positive impact on the nutritional quality of cereals purchased by households, holding all other factors constant. Given the prolific use of coupons by households and the fact that they offer both a price discount and an advertisement for products, they might be an effective way to help guide consumers to healthier food choices.

Food product differentiation leads to significant price variations among the same products, meaning that specific products can be sold in higher prices. An Hedonic Price analysis is adopted to investigate the influence of food differentiation on consumer prices and to identify product attributes’ values for the olive oil market. This will con- tribute to device the most appropriate olive oil differentiation strategies in order to be purchased by consumers in a higher price. The retail price structure was estimated in relation to several product natural attributes, to production and processing conditions, to quality control and to labeling and distribution. Findings demonstrate that olive oil price differentiation is mainly influenced by...

On the use of honesty priming task to mitigate hypothetical bias in choice

de Magistris, Tiziana; Gracia, Azucena; Nayga, Rodolfo M., Jr..

We test whether the use of an honesty priming task from the social psychology literature can help mitigate hypothetical bias in stated preference choice experiments (CE). Using a between-sample design, we conducted experiments with five treatments: (1) hypothetical CE without cognitive task, (2) hypothetical CE with cheap talk script, (3) hypothetical CE with neutral priming task, (4) hypothetical CE with honesty priming task, and (5) non-hypothetical CE. Results generally suggest that marginal willingness to pay estimates from treatment 4 where subjects are given honesty priming task before the choice experiment are not statistically different from marginal valuations from treatment 5 where subjects are in a non-hypothetical choice experiment. Values from...

Does Scarcity Exacerbate the Tragedy of the Commons? Evidence from Fishers’ Experimental Responses

Maldonado, Jorge Higinio; Moreno-Sanchez, Rocio del Pilar.

Economic Experimental Games (EEGs), focused to analyze dilemmas associated with the use of common pool resources, have shown that individuals make extraction decisions that deviate from the suboptimal Nash equilibrium. However, few studies have analyzed whether these deviations towards the social optimum are affected as the stock of resource changes. Performing EEG with local fishermen, we test the hypothesis that the behavior of participants differs under a situation of abundance versus one of scarcity. Our findings show that under a situation of scarcity, players over-extract a given resource, and thus make decisions above the Nash equilibrium; in doing so, they obtain less profit, mine the others-regarding interest, and exacerbate the tragedy of the...
