In this work, we try to find factors that determine the export continuity of Peruvian apparel exporters. Logistic regression has been used because it gives several advantages over other methods where the outcome variable is dichotomous or continuous with few values. Logit model exhibits significant interactions which have been deeply analyzed. Likewise, it was possible an exhaustive residual and goodness-of-fit analysis. Finally, we could validate the model for forecast of export continuity in 2006.

Objective: to find some determinants of financial inclusion in Colombian microenterprises for the period 2015 and 2017. Method: financial inclusion is defined from its four dimensions (access, use, quality, and wellness), and econometric probability models. Logit type is estimated, such that it allows an approximation to the determinants to effectively increase the financial inclusion of microenterprises. Results: It was found that education, the separation of household finances from microenterprise finances, business formality and Information technology and communications perform a fundamental role to comprehensively increase financial inclusion, that is, in all its dimensions. Conclusions: higher levels of financial education and knowledge of managing information technologies, financial inclusion grows in an integral way from the demand for financial services.

This research aims to show the application of the bootstrap method in the process of estimating the willingness to pay (WTP) for a determined environmental service, using the binary choice model for contingent valuation. The main contribution of the research, is the inclusion of an additional criterion in the bootstrap process, in which samples are randomly selected containing balanced values in the dependent dichotomous variable. For illustrative purposes, it is used the data base from the Postigo (2011) study, in order to estimate the mean, standard error and the confidence interval of the WTP through de bootstrap method. In comparison of the results obtained in the baseline scenario, if the bootstrap method with balanced subsamples is applied, it would be obtained logit coefficients with greater statistical significance and also lower mean and standard error of the WTP.

La presente investigación tiene como objetivo mostrar la aplicación del método bootstrap dentro del proceso de estimación de la disposición a pagar (DAP) de un determinado bien y/o servicio ambiental, bajo el enfoque de la valoración contingente de formato binario. El principal aporte de la investigación, es la inclusión de un criterio adicional en el proceso de remuestreo bootstrap, seleccionándose aleatoriamente muestras que contengan valores balanceados en la variable dependiente binaria. Con fines ilustrativos, se utilizó la base de datos del estudio de Postigo (2011), con el objetivo de estimar la media, el error estándar y el intervalo de confianza de la DAP mediante bootstrap. En comparación con los resultados obtenidos usando un remuestreo convencional, al aplicarse el bootstrap con muestras balanceadas, se obtuvo una disminución del promedio y error estándar estima...

Uno de los métodos de valoración económica más conocidos es denominado valoración contingente. En su aplicación, los encuestados responden una pregunta sobre su disposición a pagar (DAP) por el uso y preservación de un bien público. Sin embargo, este método tiene una seria limitación relacionada con la posibilidad de obtener sesgo hipotético, debido a la falta de honestidad en las respuestas, lo que produce un desbalance en el tamaño de los grupos de respuestas negativas (no dispuestas a pagar) y positivas (dispuestas a pagar). Utilizando datos de valoración contingente del Bosque Reservado de la Universidad Nacional Agraria de la Selva (BRUNAS), se calculó la DAP utilizando diferentes modelos de regresión logística binaria. El primer modelo se obtuvo considerando el conjunto original de datos con grupos no balanceados. El segundo modelo se estimó luego de aplicar el al...

The study analyzes the conservation value of forests assigned to indigenous populations of the Peruvian Amazon: San Jacinto and Puerto Arturo in Madre de Dios, communities with different realities in terms of conservation and forest management. Two scenarios prevail here: The San Jacinto indigenous community with 7 033,98 ha of forest, is characterized by disorder and the development of activities that put the community at risk (gold mining), while Puerto Arturo with 3 731 ha is a community committed to the management and conservation of its resources. By means of the Contingent Valuation Method (CVM) through the dichotomous logit model we try to define the willingness of the individuals to accept compensation (WAC) on proposed prices of a hypothetical scenario. The results show that the average annual WAC to implement the environmental program was S/ 20,46 (USD 6,30) and S/ 14,84 (USD 4...

Objective. Determine the factors that explain school dropout in the Huánuco region, Peru, for the period 2010 - 2020. Methods. The research was of an applied type, it adopted an explanatory level and a non-experimental design. Two perspectives on school dropout (individual and institutional perspective) and data from the National Household Survey were used as a theoretical basis for the estimation of a logistic regression model. Results. It was found that the probability of school dropout increases: (i) regarding socioeconomic factors, if the student belongs to a household with a low socioeconomic level (2.985 pp.), lives in a single-parent family (0.234 pp.), has dropout parent’s basic education (4,013 pp.); (ii) regarding personal factors, if the student is older (0.801 pp.), or is male (0.856 pp.), or has the need to work (1.986 pp.). Conclusions. It is established that the socioec...

La presente investigación intenta encontrar los principales factores que determinan la continuidad de las empresas de confecciones del Perú en la actividad exportadora. El uso de la regresión logística fue inevitable debido a las ventajas que ofrece sobre otros métodos en el tratamiento de variables de respuesta dicotómica y ante la presencia de covariables que pueden ser también dicotómicas o continuas con pocos valores. El modelo logit ajustado presenta interacciones significativas las cuales fueron ampliamente analizadas en este trabajo, asimismo, se realizó un exhaustivo análisis de residuos y bondad de ajuste y, finalmente, se pudo validar el modelo para pronóstico de continuidad de las empresas de confecciones en el año 2006.

Objectives: Traditional stated-preference models with fixed effects assume that individuals behave similarly. However, empirical evidence has shown that individuals’ preferences are often diverse. Hierarchical Bayesian models that include random effects provide individual-specific utilities to account for heterogeneity. This research studies oncologists’ choices about various pharmaceutical therapies for patients who have metastatic breast cancer. Methods: In this discrete choice experiment conducted in Lima, Peru, each of 113 oncologists was presented with 11 choice tasks (each consisting of four scenarios of therapies plus the NONE option) and asked to pick the best choice. The attributes included Treatment Scheme, Patient Recovery Status, Treatment Length, Cost, and Risk Factors. Hierarchical Bayesian methods were used in this multinomial logit conjoint analysis to account for het...

The growth of micro-credit along with the excellent conditions to carry out microfinance activity in the economy and financial system of the Republic of Peru are pushing for Microfinance Institutions (IMF) increased competition with banks in this segment business. Like in commercial banks, in microfinance questions such as: is this customer profitable?, What is the credit limit that I must accept to his/her application?, What interest rate should I charge to him/ her?, How I can reduce the risk default?, etc., are matters to be assessed properly. We propose a method that could facilitate improvement in customer qualification between failed and not failed. To this end, we propose a methodology that analyzes credit risk in the provision of microcredit through the design of a credit scoring model that we apply to a Development Agency for Small and Micro Enterprise (EDPYME), which is an IMF ...
