The purpose of this study is to examine the effect of the rural household’s head and household characteristics on credit accessibility. This study also seeks to investigate how credit constraint affects rural household welfare in the Mezam division of the North-West region of Cameroon. Using data from a household survey questionnaire, we found that 36.88% of the households were credit-constrained, while 63.13% were unconstrained. A probit regression model was used to examine the determinants of households’ credit access, while an endogenous switching regression model was used to analyze the impact of credit constraint on household welfare. The results from the probit regression model indicate the importance of the farmer’s or trader’s organization membership, occupation, and savings to the household’s likelihood of being credit-constrained. On the other hand, a prediction from the endogenous switching regression model confirms that households with access to credit have a better standard of welfare than a constrained household. From the results, it is necessary for the government to subsidize microfinance institutions, so that they can take on the risk of offering credit to rural households.

Production and  profit from maize farming can be substantially increased by allocating resources efficiently and adopting improved maize variety. In this context, a study was undertaken to determine the allocative efficiency and factors affecting adoption of improved maize variety in Eastern hills of Nepal. Random sampling was conducted in eastern part of Khotang district namely, Halesi municipality and Diktel Rupakot Majuwagadi municipality during month of March 2019. Pretested semi-structured questionnaire was administered among 80 randomly selected farmers cultivating maize since last two years. Face to face interview was scheduled to obtain data. Cobb Douglas production function was used to determine allocative efficiency; probit regression model was launched to determine factors affecting adoption of improved maize variety.  Significant positive relation of cost of seed, planting, and weeding with income has suggested to increase expenditure on certified maize seed over own farm seed, line sowing over broadcasting, and weeding. The model revealed that increasing all the factors of production by 100% would result in increase in income by 71.83%. Furthermore, cultivating improved maize variety is more profitable than own farm seed. Probit regression model showed that, farmers who have received training, who were member of cooperatives and who have received high schooling were more likely to adopt open-pollinated improved maize variety. Unavailability of inputs (seed, fertilizer, and labor), insect pest attack and adverse climatic conditions were major constraint of maize farming. Therefore, it would be better to suggest maize producers to increase expenditure on seed; make maize field weed free and adopt line sowing method. In addition, providing training, increasing access over inputs and encouraging farmers towards cooperatives could be virtuous for sustainable maize production.

AbstractWe try to analyze the impact of Chinese Textile and Garment (T&G) imports, and the internal and external factors to the firm survival and growth of T&G industry in Indonesia, for the period study of 2002 to 2007. Probit regression model is used to analyze the impact of Chinese imports to the survival of firm, while OLS regression model is used to analyze its growth. It shows that the ability of firms' survival is influenced by the internal and external factors. The Chinese imports give positive impact to the firms' survival ability. On the other hand, firm's growth is only affected by its internal characteristics, while the impact of Chinese imports is proven not significant. The Heckman test result stated that there are no correlation between firms' ability to survive and the firm growth behavior.Keywords: Growth, Survival, Chinese Imports, Textile, Indonesian Textile and Garment IndustryAbstrakStudi ini menganalisis dampak dari penetrasi impor TPT Cina, faktor internal, serta faktor eksternal terhadap kebertahanan dan pertumbuhan perusahaan dalam industri TPT Indonesia periode tahun 2002-2007. Metode probit regression digunakan untuk mengetahui dampak impor Cina terhadap kebertahanan perusahaan, sementara regresi linear sederhana (OLS) digunakan untuk menganalisis pertumbuhannya. Ditemukan bahwa kebertahanan perusahaan dipengaruhi oleh karakteristik internal dan eksternal, serta impor Cina yang memberikan dampak positif. Sementara pertumbuhan perusahaan hanya dipengaruhi oleh faktor internal, di mana impor Cina tidak memberikan dampak signikan. Hasil pengujian Heckman menyatakan tidak ada indikasi hubungan antara kebertahanan perusahaan dengan perilaku pertumbuhannya.Kata kunci: Pertumbuhan, Kebertahanan, Impor Cina, Tekstil, Industri Tekstil dan Produk Tekstil Indonesia

The Relationship

Human trafficking has received increased media and national attention. Despite concerted efforts to combat human trafficking, the trade in persons persists and in fact continues to grow. This paper describes the relationship and distinction between trafficking and ethnic fragmentation, conflict, internally displaced person by different measures of control. To explain the relationship between these factors, this study uses a Probit regression model. It appears that ethnic conflict leads the internal displacement of individuals from networks of family and community, and their access to economic and social safety nets. Dhaka Univ. J.

Bayesian Probit Regression

There is not much literature on objective Bayesian analysis for binary classification problems, especially for intrinsic prior related methods. On the other hand, variational inference methods have been employed to solve classification problems using probit regression and logistic regression with normal priors. In this article, we propose to apply the variational approximation on probit regression models with intrinsic prior. We review the mean-field variational method and the procedure of developing intrinsic prior for the probit regression model. We then present our work on implementing the variational Bayesian probit regression model using intrinsic prior. Publicly available data from the world’s largest peer-to-peer lending platform, LendingClub, will be used to illustrate how model output uncertainties are addressed through the framework we proposed. With LendingClub data, the target variable is the final status of a loan, either charged-off or fully paid. Investors may very well be interested in how predictive features like FICO, amount financed, income, etc. may affect the final loan status.
