description: The most entropic fluid can be related to a dense gas of black holes that we use to study the beginning of the universe. We encounter difficulties to compatibilize an adiabatic expansion with the growing area for the coalescence of black holes. This problem may be circumvented for a quantum black hole fluid, whose classical counterpart can be described by a percolating process at the critical point. This classical regime might be related to the energy content of the current universe.

description: El presente documento presenta una medición de impacto del programa de capacitación laboral juvenil PROJoven. Se utilizó información socio-laboral de una muestra de beneficiarios y un conjunto de individuos que conformaron el grupo de control. Esta información fue recogida antes de iniciados los cursos de capacitación de la sexta convocatoria (línea de base) y después de seis meses de concluido el programa por parte de los jóvenes beneficiarios (primera medición de salida). La muestra total de beneficiarios disponible para la evaluación fue de 1,018, representando poco menos del 30% del total de jóvenes atendidos en la sexta convocatoria de PROJoven. Asimismo, se contó con información para 1,561 potenciales controles, es decir, individuos que poseen características comparables a las de los beneficiarios pero que no fueron parte del programa. El objetivo es comparar la nueva situación económica de los beneficiarios, como consecuencia de su participación en PROJoven, con la situación que hubiesen alcanzado en el caso de no haber asistido al programa.

description: Casi cinco años después de haber culminado las privatizaciones en telecomunicaciones y electricidad, así como haber realizado importantes reformas en agua potable y alcantarillado, es necesario realizar un balance sobre los resultados de dichas reformas. A fin de determinar si el resultado fue positivo o negativo, esta investigación trata de cuantificar los efectos de las privatizaciones de los servicios públicos (agua, telecomunicaciones y electricidad) sobre el consumo y bienestar de los hogares urbanos peruanos. Por tanto, nuestro principal objetivo es analizar los efectos sobre la distribución del ingreso e identificar que hogares se beneficiaron y cuales se perjudicaron por los cambios en precios originados por las privatizaciones. Para lograr este objetivo se aplican tres metodologías complementarias. La primera estima curvas de concentración para mostrar como se distribuyen los servicios entre la población. La segunda metodología, basada en Waddams-Price y Hancock (1998), mide cambios en el gasto de los hogares inducidos por cambios en los niveles de precios de los servicios y su estructura relativa. Finalmente, estimamos ecuaciones de demanda para los diferentes servicios analizados, aplicando la metodología en dos etapas de Heckman para corregir por la probabilidad de acceder al servicio. Utilizando la elasticidad de demanda así estimada se calcularon los cambios en el bienestar de los consumidores de dichos servicios.

Example of the data presentation used in this study. In order to account for the high number of time points analyzed (17) during the three phases of the MBRA experiments (pre-treatment, treatment and post-treatment), data of bacterial density, alpha and beta diversity analysis of microbiota composition and pro-inflammatory potential were processed and presented as exemplified here for the Jaccard measurement of beta diversity of microbiota composition. A. Principal coordinate analysis at each individual time points. B. Histograms of Jaccard distance separating control samples from every other condition – including control themselves. C-D. These various time points were subsequently combined in a XY representation with two normalizations steps : the distance separating control samples from themselves were normalized as 1 (C) in order to account for inter-chambers and day-to-day variations, and the distance observed at the 24 h time point were normalize as 1 (D) in order to account for pre-treatment inter-chambers variations. E. Finally, area under the curve was determined for the treatment phase (72 h > 216 h) and the post-treatment phase (216 h > 274 h) in order to present, for both phases, the global impact of emulsifier exposure on microbiota composition and function. Data are the means +/- S.E.M (N = 3). *P

description: The Cressie-Read (CR) family of power divergence measures is used to identify a new class of statistical models and estimators for competing explanations of the data in binary choice models. A large flexible class of cumulative distribution functions and associated probability density functions emerge that subsumes the conventional logit model, and forms the basis for a large set of estimation alternatives to traditional logit and probit methods. Asymptotic properties of estimators are identified, and sampling experiments are used to provide a basis for gauging the finite sample performance of the estimators in this new class of statistical models.

description: Organic multiferroic tunnel junctions (OMFTJs) with multi-resistance states have been proposed and drawn intensive interests due to their potential applications, for examples of memristor and spintronics based synapse devices. The ferroelectric control of spin-polarization at ferromagnet (FM)/ferroelectric organic (FE-Org) interface by electrically switching the ferroelectric polarization of the FE-Org has been recently realized. However, there is still a lack of understanding of the transport properties in OMFTJs, especially the interplay between the ferroelectric domain structure in the organic barrier and the spin-polarized electron tunneling through the barrier. Here, we report on a systematic study of the temperature dependent transport behavior in La0.6Sr0.4MnO3/PVDF/Co OMFTJs. It is found that the thermal fluctuation of the ferroelectric domains plays an important role on the transport properties. When T>120K, the opposite temperature dependence of resistance for in up and down ferroelectric polarization states results in a rapid diminishing of tunneling electroresistance (TER). These results contribute to the understanding of the transport properties for designing high performance OMFTJs for memristor and spintronics applications.

description: El presente documento de trabajo tiene por objeto presentar y analizar los datos de la evaluación del impacto educativo de un programa de desayunos escolares en escuelas rurales de la zona altoandina del Perú. En la evaluación se comparan medidas de peso, talla, tasas de matrícula y deserción escolar, asistencia, aptitudes cognoscitivas y rendimiento en pruebas estandarizadas de matemática y comprensión de lectura en estudiantes de cuarto grado de primaria de un grupo de tratamiento que recibió desayuno por al menos tres años y un grupo de contraste, que no participó del programa. Se encontraron resultados positivos para el grupo de tratamiento en memoria de corto plazo, hemoglobina, tasa de deserción escolar y asistencia diaria a la escuela. Los resultados no muestran diferencias entre los dos grupos en talla para edad, índice de masa corporal, ni en pruebas de rendimiento escolar. La ausencia de efectos positivos en las pruebas de rendimiento en el grupo de tratamiento puede relacionarse a que el tiempo que los alumnos estaban en el aula con el profesor disminuyó luego de la introducción del programa de desayunos y/o a la mayor tasa de deserción en el grupo de contraste durante los tres años anteriores a la evaluación. Los resultados son de interés para las partes involucradas en el programa, pero también para un público más amplio de evaluadores de programas e investigadores interesados en los determinantes del rendimiento escolar en zonas pobres de países en vías de desarrollo.

A geostrophic-like model for large Hartmann number flows
Creators: name: Alboussiere, Thierry
Publisher: name: arXiv
Year: 2005
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: A flow of electrically conducting fluid in the presence of a steady magnetic field has a tendency to become quasi two-dimensional, i.e. uniform in the direction of the magnetic field, except in thin so-called Hartmann boundary layers. The condition for this tendency is that of a strong magnetic field, corresponding to large values of the dimensionless Hartmann number (Ha >> 1). This is analogous to the case of low Ekman number rotating flows, with Ekman layers replacing Hartmann layers. This has been at the origin of the homogeneous model for flows in a rotating frame of reference, with its rich structure: geostrophic contours and shear layers of Stewartson, Munk and Stommel. In magnetohydrodynamics, the characteristic surfaces introduced by Kulikovskii play a role similar to the role of the geostrophic contours. However, a general theory for quasi two-dimensional magnetohydrodynamics is lacking. In this paper, a model is proposed which provides a general framework for quasi two-dimensional magnetohydrodynamic flows. Not only can this model account for otherwise disconnected past results, but it is also used to predict a new type of shear layer, of typical thickness Ha^{-1/4}.

description: The $α$-$z$ Rényi relative entropies are a two-parameter family of Rényi relative entropies that are quantum generalizations of the classical $α$-Rényi relative entropies. In \cite{zhang20CFL} we decided the full range of $(α,z)$ for which the Data Processing Inequality (DPI) is valid. In this paper we give algebraic conditions for the equality in DPI. For the full range of parameters $(α,z)$, we give necessary conditions and sufficient conditions. For most parameters we give equivalent conditions. This generalizes and strengthens the results of Leditzky, Rouz{é} and Datta in \cite{LRD17DPI}.

description: We present the calculation of the next-to-next-to-leading order (NNLO) zero-jettiness beam and soft functions, up to the second order in the expansion in the dimensional regularization parameter $ε$. These higher order terms are needed for the computation of the next-to-next-to-next-to-leading order (N$^3$LO) zero-jettiness soft and beam functions. As a byproduct, we confirm the $O(ε^0)$ results for NNLO beam and soft functions available in the literature.

description: En este estudio se construyen indicadores de desempeño a partir de las propias percepciones de los maestros acerca de su rendimiento, de sus posibilidades de tomar decisiones y de tener un efecto sobre el desempeño de los alumnos. Estos indicadores no miden el desempeño propiamente dicho, sino más bien intentan medir determinadas actitudes que usualmente se asocian con un mejor desempeño en el aula. Se encuentra que, controlando por las características de los maestros y de los alumnos, los maestros de escuelas privadas tienen una mejor percepción de su propio desempeño. Las diferencias en favor de los docentes privados pueden estar reflejando diferencias organizacionales entre ambos tipos de escuelas y diferencias en la estructura de estímulos y de incentivos.
The effect of Joule heating on the terahertz radiation in the superconductor media

description: Moving vortex lattice in type-II superconductors can result in the radiation of electromagnetic waves in the range of terahertz frequency. The vortex flow dynamics in superconductors follow the London equation. In this paper, the effects of the superconductor coherence length and the London penetration depth on the radiated power is investigated by solving the London equation in the presence of vortices. The results show that by decreasing the coherence length, the radiation power will significantly increase. Also, it is possible to obtain more radiated power with a sharp peak by increasing the penetration depth. Further investigation of the effect of Joule heating reveals that radiation power is almost independent of temperature when we are far from critical temperature. But on the other hand, near the critical temperature, the radiation power is strongly dependent on the temperature variation. Also, by increasing the bias current, the radiation power will augment, and the frequency of radiated peaks will change accordingly.

description: El efecto del nivel de salud de los individuos sobre su productividad y sus ingresos es incuestionable desde varios puntos de vista. Sin embargo, la medición de ese efecto ha sido bastante más complicada que, por ejemplo, la correspondiente al efecto de la educación. Las razones de esta complejidad son de carácter conceptual, técnico y de calidad de la información. Esta medición se complica aún más en países en desarrollo debido a las limitaciones de los indicadores de salud disponibles, en su mayoría afectados por la propia percepción del individuo. En este sentido, el presente reporte muestra evidencia acerca de los determinantes de salud para los varones adultos de zonas urbanas y sus efectos en la productividad, usando dos medidas de morbilidad autoreportadas: el número de días de enfermedad y el número de días de incapacidad. Ambas se encuentran afectadas por el problema de la endogeneidad, pero parecen diferir en la magnitud del error de reporte asociado a ellas.
Nitrosyl complexes of vanadium, niobium, tantalum, tungsten, and iron

description: Treatment of V(CO)₅(NO) with trimpsi (trimpsi = BuSi(CH₂PMe₂)₃), followed by heating in THF, generates (trimpsi)V(CO)₂NO in moderate yields. (trimpsi)V(CO)₂NO has been studied by X-ray crystallography, ⁵¹V{¹H} NMR spectroscopy, and cyclic voltammetry. (trimpsi)V(CO)₂NO can be oxidised by the reaction with [Cp₂Fe] [BF₄], generating [(trimpsi) V(CO)₂NO] [BF₄]. Treatment of (trimpsi) V(CO)₂NO with one equiv of PhICl₂, Br₂, or I₂, or two equiv of C1NO, generates (trimpsi)VX₂ (NO) (X = CI, Br, I) in good yields. Treatment of (trimpsi)M(CO)₂NO (M = Nb, Ta) with I₂, followed by addition of excess PMe₃, provides (trimpsi)MI₂(NO)(PMe₃) in low to moderate yields. The reaction between (trimpsi)M(CO)₂NO (M - Nb, Ta) with one equiv of C1NO provides (trimpsi)M(NO) ₂Cl. These two complexes are thermally sensitive and have only been characterised by low-temperature IR and NMR spectroscopies. Treatment of (trimpsi)VCl₂ (NO) with p-toluic acid and Proton Sponge provides (trimpsi)V(O₂CPh-4-Me)₂(NO) in moderate yield. Alternatively, treatment of (trimpsi) V(CO)₂NO with benzoyl peroxide also generates a carboxylate complex, namely (trimpsi)V(O₂CPh)₂(NO). The reaction between (trimpsi)VCl₂(NO) and 0.5 equiv of MgR₂x(dioxane) (R = CH₂SiMe₃, CH₂CMe₃, Me) forms (trimpsi)V(R)Cl(NO) in good yields. Several attempts to form complexes of the type (trimpsi)VR₂(NO) have been unsuccessful. Treatment of [V(NO)₃Cl2][sub n] with excess THF generates mer-(THF)₃VCl₂(NO) in good yield. The reaction of mer-(THF)₃VCl₂(NO) with excess MeCN generates fac- (MeCN)₃VCl₂(NO). Both complexes have been characterised by X-ray crystallography. The reaction of VCI₄ with NO has been found to generate [NO][VCl₅] and VCI₃. [NO][VCl₅] can also be formed by the reaction of VC1₄ and C1NO. Treatment of [NO][VCl₅] with excess [NEt₃CH₂Ph][Cl] generates [NEt₃CH₂Ph]₂[VCl₆] in moderate yield, while exposure of a DME solution of [NO][VCl₅] to air generates (DME)VC1₂(O)(μ-O)V(O)C1₂(DME). The reaction between Fe(NO)₃Cl and [Ag][X] (X = BF₄, PF₆) forms Fe(NO)₃(η¹-X) in moderate yields. Alternatively, Fe(NO)₃( η¹-X) can also be formed by the action of [NO][X] upon Fe powder. Fe(NO)₃( η¹-BF₄) has been characterised by X-ray crystallography. During the course of this research [Fe(NO)₃(EtCN)][PF₆] and [Fe(NO)₃(μ-PO₂F₂)Fe(NO)₃][PF₆] have also been isolated and structurally characterised. The iron trinitrosyl complexes exhibit bent nitrosyl linkages and a molecular orbital rationale is given to explain these metrical parameters. The solid-state molecular structure of another trinitrosyl complex, namely fac-W(NO)₃C1₃, was also determined. fac-W(NO)₃Cl₃ exhibits linear nitrosyl ligands, and a rationale is provided to explain the difference between the iron and tungsten cases.

description: In order to understand the bounds of utilization of the Grover's search algorithm for the large unstructured data in presence of the quantum computer noise, we undertake a series of simulations by inflicting various types of noise, modelled by the IBM QISKit. We apply three forms of Grover's algorithms: (1) the standard one, with 4-10 qubits, (2) recently published modified Grover's algorithm, set to reduce the circuit depth, and (3) the algorithms in (1) and (2) with multi-control Toffoli's modified by addition of an ancilla qubit. Based on these simulations, we find the upper bound of noise for these cases, establish its dependence on the quantum depth of the circuit and provide comparison among them. By extrapolation of the fitted thresholds, we predict what would be the typical gate error bounds when apply the Grover's algorithms for the search of a data in a data set as large as thirty two thousands.

description: El objetivo de esta investigación es evaluar empíricamente los factores que determinan las estrategias de vinculación al mercado de los productores agrarios en el Perú. Asimismo, estudia el papel de los costos de transacción en el comportamiento de los hogares rurales. Además, la investigación plantea e implementa una propuesta metodológica para cuantificar los costos de transacción. Los resultados muestran que los costos de transacción en el área bajo estudio (los distritos de Pazos y Huaribamba, en Tayacaja, Huancavelica) equivalen a 50 % del valor de venta y son apreciablemente más altos (60 %) para los productores conectados al mercado a través de caminos de herradura que para aquellos vinculados al mercado a través de caminos carrozables, confirmando la importancia de la inversión en infraestructura de caminos rurales. Se confirma también que los costos de transacción son bastante mayores para los pequeños que para los grandes productores (67 % frente a 32 % del valor de venta). Los resultados muestran que no sólo la distancia o el tiempo al mercado son variables cruciales para explicar la estrategia de vinculación al mercado (esto es, cuánto vender y a qué mercado), sino también diversos indicadores como la experiencia del productor en el mercado donde opera, la estabilidad de sus relaciones con los agentes con que comercia y los recursos que invierte en obtener información relevante y en supervisar el cumplimiento de los contratos implícitos asociados a las transacciones realizadas.

description: Greenhouse horticulture can play a major role in Flemish rural development, regional economy and employment. However, the sector deals with structural problems. Scale increase of greenhouse firms is required for economic reasons, but high investments and risks make this quasi unsupportable for individual farmers. Clustering greenhouses into greenhouse parks is a possible way out. Through collaboration and mutual material exchanges, firms enjoy scale effects and eco-efficiency is enhanced without individual enlargement. The government is planning pilot projects to investigate possibilities of greenhouse parks in Flanders. Obviously, many obstacles are faced, such as spatial planning, coordination of policy levels and institutions and interactions with different stakeholders, e.g. local people, environmentalists, the distribution sector. Moreover, the mere set-up of such a high impact process is a challenge. We look at similar projects, implemented in the Netherlands in order to obtain a better view on possibilities, critical success factors, triggers and threats for greenhouse parks in Flanders. Dutch cases of successes and failures are explored by case study research. After the first data gathering round, only preliminary results are presented. Different concepts such as transition and system innovation are used as theoretical lenses in the analysis. In a later phase of the research, information and lessons learned from Dutch projects will be combined with research data of Flanders. First results indicate the importance of “Related activities in the neighbourhood”, “Land”, “Financial conditions”, “Role of different policy levels”, “Support of stakeholders”, “Collaboration” and “Process specific parameters”.

The case study is the olive (Olea europaea L.) plantations of the mountain areas of Andalusia (Spain) which, because of their low yield, are likely to be abandoned after the decoupling of the EU olive oil subsidies. The results suggest that the edge of major agricultural areas (mostly olive groves), the natural vegetation and areas adjacent to Natural Park with oaks would be most suitable for wildlife habitat restoration. These results are in agreement other studies carried out by other researchers on biodiversity, based on either individual or groups of species.

description: In this paper, we investigate whether people’s knowledge of the past influences their preferences and values towards future landscape change. “Knowledge of the past” is one aspect of the information set held by individuals, and a well-established finding in stated preference work is that changes in information can change preferences and values. The case studies used here relate to prospective changes in woodland cover in a UK national park the Lock Lomond and Trossachs. We find that people who are made aware that the landscape has changed over time are more likely to favour changes to the current landscape. Knowledge of the past therefore seems to have an impact on preferences for future landscapes.

description: Public Rights of Way (PROW) in England and Wales, provides a wide range of social and economic benefits to those other than owners of land. The protection and extension of PROW are an important way of encouraging people to engage in informal enjoyment of urban and rural areas, with beneficial consequences for health and welfare. In urban areas they provide networks of mobility and interaction for people at the community level, helping to reduce reliance on motorised transport. In the rural context they define access to the countryside, critically linked to recreation and tourism, as well as providing mobility networks for local residents. This study describes the use of a Choice Experiment (CE) to derive monetary estimates the social benefits of PROW in an English county.
The Marchenko method for evanescent waves

description: With the Marchenko method, Green's functions in the subsurface can be retrieved from seismic reflection data at the surface. State-of-the-art Marchenko methods work well for propagating waves but break down for evanescent waves. This paper discusses a first step towards extending the Marchenko method for evanescent waves and analyses its possibilities and limitations. In theory both the downward and upward decaying components can be retrieved. The retrieval of the upward decaying component appears to be very sensitive to model errors, but the downward decaying component, including multiple reflections, can be retrieved in a reasonably stable and accurate way. The reported research opens the way to develop new Marchenko methods that can handle refracted waves in wide-angle reflection data.

description: The point contact of a tunnel tip approaching towards Ag(111) and Cu(111) surfaces is investigated with a low temperature scanning tunneling microscope. A sharp jump-to-contact, random in nature, is observed in the conductance. After point contact, the tip-apex atom is transferred to the surface, indicating that a one-atom contact is formed during the approach. In sharp contrast, the conductance over single silver and copper adatoms exhibits a smooth and reproducible transition from tunneling to contact regime. Numerical simulations show that this is a consequence of the additional dipolar bonding between the homoepitaxial adatom and the surface atoms.

description: Current EU legislation states that premiums for agri-environmental schemes must be calculated based on forgone profit and additional costs. This approach has been implemented for the last decades without much success in farmer uptake, a situation that might even worsen as the 20% additional payment as incentive for participation has been excluded in the new EU Rural Development Framework 2007-2013. This paper tries to explain why supply side estimated premiums might not suffice to assure farm profitability investigating the role that fixed costs have on adoption. A farm profit maximizing model is proposed where fixed and transaction costs are split from variations in marginal profit. This model is then developed to identify the potential barriers to adoption associated with the presence of fixed compliance costs. A sample of farmers eligible for an agri-environmental scheme entailing a land-use change is used to test whether the theoretical models are valid for explaining adoption decisions. Two different econometric specifications are used to identify the role of fixed costs, one assuming that uptake and surface decisions are governed by the same variables and another distinguishing both decisions. Estimation results show that there is an adoption barrier derived from the initial farm technical assets and know-how affecting the fixed compliance costs of introducing the new crop. Therefore not compensating for fixed costs can curtail agri-environmental policy success. In addition, there is an adoption barrier derived from transaction costs which are reduced in the presence of social networks.

description: The recent line of research into topology design focuses on lowering network diameter. Many low-diameter topologies such as Slim Fly or Jellyfish that substantially reduce cost, power consumption, and latency have been proposed. A key challenge in realizing the benefits of these topologies is routing. On one hand, these networks provide shorter path lengths than established topologies such as Clos or torus, leading to performance improvements. On the other hand, the number of shortest paths between each pair of endpoints is much smaller than in Clos, but there is a large number of non-minimal paths between router pairs. This hampers or even makes it impossible to use established multipath routing schemes such as ECMP. In this work, to facilitate high-performance routing in modern networks, we analyze existing routing protocols and architectures, focusing on how well they exploit the diversity of minimal and non-minimal paths. We first develop a taxonomy of different forms of support for multipathing and overall path diversity. Then, we analyze how existing routing schemes support this diversity. Among others, we consider multipathing with both shortest and non-shortest paths, support for disjoint paths, or enabling adaptivity. To address the ongoing convergence of HPC and "Big Data" domains, we consider routing protocols developed for both HPC systems and for data centers as well as general clusters. Thus, we cover architectures and protocols based on Ethernet, InfiniBand, and other HPC networks such as Myrinet. Our review will foster developing future high-performance multipathing routing protocols in supercomputers and data centers.

description: Ashtamudi estuary of south India provides many direct and indirect use values to the local community in terms of fishing, coconut husk retting, recreation and inland navigation. Nowadays the estuary is facing many threats like pollution, reclamation, injudicious fishing practices etc. At the same time it is having many potential future uses also. So it is imperative to assess the option value of the estuary to appraise the importance to conserve it. Here a contingent valuation method is applied for the assessment. The high option value of the estuary indicates the urgent need of conserving it for the potential future uses.

description: The paper deals with the problem of finding relative values for species in the case of biodiversity conservation in a cultural landscape. We use the concept of shadow prices to derive flexible functional forms that allow us to conduct an interactive and internal valuation process. The paper is organized such as that (1) the theory of shadow price derivation is presented in a framework of programming. (2) We obtain quadratic objective functions for participant in the valuation process. (3) Quasi demand and supply functions are derived from which we can simulate a market. (5) The special role of ecologists as experts and potential managers of a landscape is ad-dressed and (6), or finally, a balanced solution on values, value oriented management, and species prevalence is provided.

description: The reduced density matrix of many-body systems possessing an additive conserved quantity can be decomposed in orthogonal sectors which can be independently analyzed. Recently, these have been proven to equally contribute to entanglement entropy for one dimensional conformal and integrable systems. In this paper, we extend this equipartition theorem to the disordered critical systems by studying the random singlet phase. We analytically compute the disorder averaged symmetry resolved Rényi entropies and show the leading orders are independent of the symmetry sector. Our findings are cross-checked with simulations within the numerical strong disorder renormalization group. We also identify the first subleading term breaking equipartition which is of the form $s^2/\ln\ell$ where $s$ is the magnetization of a subsystem of length $\ell$.

One size fits all? Female Headed Households, Income Risk, and Access to Resources

subject: income risk

description: Studies dealing with productivity in female (FHH) and male headed households (MHH) find that FHH appear to be either less, equally, or more productive compared to MHH. Lower productivity of FHH is often explained by insecure access to land, while the findings of higher productivity largely remain unexplained. This paper is an attempt to reconcile these contrasting findings by constructing a model that accounts for productivity effects arising from secure land rights and the risk of falling short of income. Both affect productivity, but they do so in opposite directions. While tenure insecurity tends to decrease labor effort, income risks increase it as subsistence farmers want to avoid falling (deeper) into poverty. Depending on which of these risks prevails in the perception of farmers, they become either more or less productive than a benchmark farmer who faces none of these constraints. The model is tested using data from Kenya where FHH are categorized by different land tenure security schemes. The results from a stochastic cost frontier model establish that FHH facing tenure insecurity are less productive compared to MHH. However, this result only obtains in case households do not face income risks.
