Are labour inspections effective when labour regulations vary according to the size of the firm? Evidence from Peru

This article analyses the impact of enforcement of four labour standards (pension system enrolment, minimum wage, maximum weekly working hours and written employment contract) on compliance in Peru, where labour regulations and penalties vary according to firm size. The author uses household survey data to analyse a factor not previously studied – adjustment by firms through downsizing to benefit from lower fines and less stringent regulations. The empirical findings indicate that enforcement efforts have little effect on either the degree of compliance or the size of firms.     

When Does Poor Governance Presage Biosecurity Risk?

Border inspection, and the challenge of deciding which of the tens of millions of consignments that arrive should be inspected, is a perennial problem for regulatory authorities. The objective of these inspections is to minimize the risk of contraband entering the country. As an example, for regulatory authorities in charge of biosecurity material, consignments of goods are classified before arrival according to their economic tariff number. This classification, perhaps along with other information, is used as a screening step to determine whether further biosecurity intervention, such as inspection, is necessary. Other information associated with consignments includes details such as the country of origin, supplier, and importer, for example. The choice of which consignments to inspect has typically been informed by historical records of intercepted material. Fortunately for regulators, interception is a rare event; however, this sparsity undermines the utility of historical records for deciding which containers to inspect. In this article, we report on an analysis that uses more detailed information to inform inspection. Using quarantine biosecurity as a case study, we create statistical profiles using generalized linear mixed models and compare different model specifications with historical information alone, demonstrating the utility of a statistical modeling approach. We also demonstrate some graphical model summaries that provide managers with insight into pathway governance.     

A sampling plan for one-shot systems considering destructive inspection

Abstract

The paper is concerned with an acceptance sampling problem under destructive inspections for one-shot systems. The systems may fail at random times while they are operating (as the systems are considered to be operating when storage begins), and these failures can only be identified by inspection. Thus, n samples are randomly selected from N one-shot systems for periodic destructive inspection. After storage time T, the N systems are replaced if the number of working systems is less than a pre-specified threshold k. The primary purpose of this study is to determine the optimal number of samples n*, extracted from the N for destructive detection and the optimal acceptance number k*, in the sample under the constraint of the system interval availability, to minimize the expected cost rate. Numerical experiments are studied to investigate the effect of the parameters in sampling inspection on the optimal solutions.     

Modified chain sampling plans for lot inspection by variables and attributes

The purpose of acceptance sampling is to develop decision rules to accept or reject production lots based on sample data. When testing is destructive or expensive, dependent sampling procedures cumulate results from several preceding lots. This chaining of past lot results reduces the required size of the samples. A large part of these procedures only chain past lot results when defects are found in the current sample. However, such selective use of past lot results only achieves a limited reduction of sample sizes. In this article, a modified approach for chaining past lot results is proposed that is less selective in its use of quality history and, as a result, requires a smaller sample size than the one required for commonly used dependent sampling procedures, such as multiple dependent sampling plans and chain sampling plans of Dodge. The proposed plans are applicable for inspection by attributes and inspection by variables. Several properties of their operating characteristic-curves are derived, and search procedures are given to select such modified chain sampling plans by using the two-point method.     

L'inspection du travail,un outil efficace quand les règles et sanctions varient selon les effectifs de l'entreprise? Analyse à partir du cas péruvien

L'auteure analyse l'effet de la rigueur du dispositif de mise en application de la législation sur le respect effectif des droits au travail lorsque les règles et sanctions dépendent des effectifs de l'entreprise. À partir de données de l'enquête auprès des ménages du Pérou (2008–2013), elle examine l'influence en la matière de facteurs déjà connus (effet dissuasif de l'inspection, glissement vers le secteur informel) mais aussi celui du «redimensionnement», stratégie utilisée par les employeurs pour se prévaloir de régimes plus favorables. Elle montre que l'intensité du dispositif de contrôle n'influe que modérément sur le degré de conformité. L'effet «redimensionnement» est lui aussi limité.     

Quality Management in Multi‐Level Supply Chains with Outsourced Manufacturing

Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection‐based approach and an external failure‐based approach, in two supply chains – a dyadic supply chain and a multi‐level supply chain where the brand owner outsources manufacturing to an independent contract manufacturer. Our study finds that the brand owner's optimal choice between the two quality management approaches could be opposite in the two supply chains. Specifically, we show that if agency costs exist between the contract manufacturer and the brand owner, the brand owner may prefer an inspection‐based approach in the multi‐level supply chain in contrast to preferring an external failure‐based approach in the dyadic supply chain. In particular, inspections can be effective for the brand owner to limit the manufacturer's profit by excluding defective finished products and components, which in turn reduce agency costs in the multi‐level supply chain. Hence, the efficiency of an inspection‐based approach relative to an external failure‐based approach can be higher in the multi‐level supply chain as compared to the dyadic one. Our findings suggest that firms should adjust to changes in supply chain structures and re‐evaluate the efficiencies of different quality management approaches accordingly.

高校纪检法制化建设研究

高校对于一个现代国家的发展起着非常关键的作用。高校纪检法制化要通过法制宣传，提高高校纪检法制观念，建立起一套系统的纪检制度和配套的纪检保障机制，从而实现高校纪检的法制化，为迈向法治化奠定规范基础。     

论苏区邮政检查的操作方法与纪律

为了获得情报，肃清内奸，加强宣传，反制敌方邮检，苏区实行了邮检制度。邮检对象包括：密写、密函信件，记录有军政情报内容的胶卷、录音带、录像带、报刊杂志，夹藏有显微点以及炸弹、毒品、恐吓信、内容反动的信件或者出版物。邮检方式主要有四种。对受检邮件的处理方式有三种。总之，苏区对邮检极为重视，除严格选拔邮检员外，还制定了纪律，操作也较规范。
