The Antecedent-Behavior-Consequence (ABC)-analysis is a tool for analyzing behavior and stems from the field of psychology where it is used as a tool for the understanding of behavior in general and organizational behavior in particular. In this paper the ABC-analysis is implemented as a tool to understand why people behave ethically in organizations, through the identification of key environmental factors that cause such behavior. This analysis can be the first step to recognizing the complexity of circumstances determining ethical behavior, as well as trigger for changing that behavior. This will be elaborated in the implementation process of an ethical code. The working of the ABC-analysis will be illustrated with an example derived from field research concerning the reorganization of a department of a chemical company.  相似文献

We use an intensity-based framework to study the relation between macroeconomic fundamentals and cycles in defaults and rating activity. Using Standard and Poor's U.S. corporate rating transition and default data over the period 1980–2005, we directly estimate the default and rating cycle from micro data. We relate this cycle to the business cycle, bank lending conditions, and financial market variables. In line with earlier studies, the macro variables appear to explain part of the default cycle. However, we strongly reject the correct dynamic specification of these models. The problem is solved by adding an unobserved dynamic component to the model, which can be interpreted as an omitted systematic credit risk factor. By accounting for this latent factor, many of the observed macro variables loose their significance. There are a few exceptions, but the economic impact of the observed macro variables for credit risk remains low. We also show that systematic credit risk factors differ over transition types, with risk factors for downgrades being noticeably different from those for upgrades. We conclude that portfolio credit risk models based only on observable systematic risk factors omit one of the strongest determinants of credit risk at the portfolio level. This has obvious consequences for current modeling and risk management practices.  相似文献

This study's goal was to establish the prevalence of driving under the influence of alcohol (DUI) and alcohol consumption patterns among drivers in Cali, Colombia, in 2013. A cross-sectional study based on a roadside survey using a stratified and multi-stage sampling design was developed. Thirty-two sites were chosen randomly for the selection of drivers who were then tested for blood alcohol concentration (BAC) and asked to participate in the survey. The prevalence of DUI was 0.88% (95% confidence intervals [95% CI] 0.26%–1.49%) with a lower prevalence when BAC was increasing. In addition, a higher prevalence was found during non-typical checkpoint hours (1.28, 95% CI ?0.001%–0.03%). The overall prevalence is considered high, given the low alcohol consumption and vehicles per capita. Prevention measures are needed to reduce DUI during non-typical checkpoints and ongoing studies are required to monitor the trends and enable the assessment of interventions.  相似文献

Suppliers are expected to reduce manufacturing firm supply risks by minimizing supply failures and by resolving supply problems, even those ones resulting from firm’s actions. Integration mechanisms may enhance interaction and collaboration in the firm supply chain, especially in the buyer-supplier interface, to reach these goals. Based on case studies in four North-American manufacturing companies in the electronic and aerospace industries, we analyzed the importance of integration mechanisms for manufacturing firms to address supply problems. We also explored some drivers supporting those mechanisms. Supplier commitment was found to be a key integration factor to address supply problems. This may be accomplished by trust and power mechanisms. Internal integration between purchasing and manufacturing groups also played a significant role in supplier collaboration at the problem solving process. Customer integration seemed more important to address supply problems for contract manufacturers than for Original Equipment Manufacturing (OEM) firms. Although supply problems might originate several stages upstream in the supply chain, surprisingly there was no integration beyond direct suppliers in the manufacturing firm supply chain.  相似文献

This paper studies the relation between inflation and economic development. The literature is largely silent regarding both the theoretical and empirical perspectives that undeveloped countries endure higher average inflation than developed economies. We present a simple theoretical model linking the inflation phenomenon to the tradition of development economics. Empirical evidence is garnered to test the hypothesis that economic development engenders a downward bias to inflation rates. Through the feasible-GLS estimator in a panel of 65 countries from 2001 to 2011, we aim at listing a number of variables most commonly used to explain differences in the stage of economic development across countries and identifying the most statistically relevant ones to account for differences in inflationary patterns. While our results show that inflation is inversely correlated with the level of the technological content of the economy (measured by share of high-tech exports), human capital and cyclical unemployment, it is directly related to the degree of inflation persistence and terms of trade growth. However, our findings still present an inverse and low correlation between inflation persistence and economic development, implying that development-sensitive variables allowed into the model can only partially account for the differences in inflation at different levels of economic development.  相似文献

Historically, some societies around the world killed newborn twins, though the practice was forsaken in the early twentieth century. Anthropologists have proposed different theses: (1) the delivery of twins occurred when the mother cheated on her husband, or committed a great sin, and killing the twins was the penalty, (2) twin-killing was done to assert that human beings were different from animals among which multiple births in the same delivery were seen, (3) twins brought a dilemma to the kinship structure of societies and to cope with it different rules were adopted, twin-killing being the extreme one, (4) twin-killing was a means to face resource stress. We argue that although those interpretations are useful, we can improve the understanding of that phenomenon by adding an identity economics model, where twins are a taboo. Identity economics helps us explain the persistence of the practice and its eventual decline. We make our case with examples from the Igbo of Nigeria.  相似文献

This article computes input-specific scores of technical efficiency for a sample of water utilities located in the southern Spanish region of Andalusia. In addition, differences in efficiency between different operating environments are investigated. Concerning the debate about ownership and efficiency, we find that privately owned companies outperform public utilities in their management of labour. Furthermore, technical efficiency is found to be greater among firms located in highly populated areas and for utilities providing water services to tourist municipalities. Finally, no empirical evidence supporting the greater technical efficiency of consortia of water utilities, a managerial strategy strongly encouraged by regional politicians, is found.  相似文献

Abstract

While a large body of literature examines the environmental impact of trade on the environment, this discussion focuses largely on the context of inter-industry trade. Empirical evidence has long suggested that an increasing share of international trade takes the form of intra- rather than inter-industry trade. In an attempt to fill this gap, the present paper uses a price-setting duopoly model of intra-industry trade to highlight the environmental consequences of trade liberalization when oligopolistic rivalry rather than comparative advantage drives international trade. We find that the environmental impact of trade liberalization depends mostly on two factors, namely, on the nature of pollution (i.e. whether it is local, transboundary or global) and on which country liberalizes trade (i.e. whether it is the ‘clean’ country or the ‘dirty’ country).  相似文献
