Finding Closest Targets in Non-Oriented DEA Models: The Case of Convex and Non-Convex Technologies

This paper draws attention for the fact that traditional Data Envelopment Analysis (DEA) models do not provide the closest possible targets (or peers) to inefficient units, and presents a procedure to obtain such targets.It focuses on non-oriented efficiency measures (which assume that production units are able to control, and thus change, inputs and outputs simultaneously) both measured in relation to a Free Disposal Hull (FDH) technology and in relation to a convex technology. The approaches developed for finding close targets are applied to a sample of Portuguese bank branches.     

Severance Payment Programs in Latin America

Latin America stands out among different regions in the world for her high employment termination costs. To this contribute both a high level of severance payments and the existence of overlapping benefits. The effectiveness of these protective measures, however, is limited by the size of the informal sector, which, in turn, may be related to employment protection levels. Another important limitation on the effectiveness of employment protection regulation is the often large transaction costs associated with making good of law provisions for the worker. Equilibrium severance pay levels may thus be well below what law mandates as evidence of low coverage rates and undesirable side effects is mounting, reform seems a critical policy issue. However, this reform cannot focus exclusively on severance pay, but it has to incorporate other overlapping benefits, such as UISAs, and advance notice. It also has to contend with a problematic political economy. Jaramillo is a Senior Researcher at the Group for Analysis of Development, GRADE. Saavedra is with the World Bank.

Geometrical Interpretation of the Mean and the Constant in a Box-Jenkins Time Series Model

Certain manuals and computer programs mistakenly identify the mean with the constant in Box-Jenkins time series models. In this paper, it will be shown that (a) the mean and the constant have different values in autoregressive models, and (b) they have an algebraic and graphical relationship.     

Integrating Environmental,Social and Governance (ESG) Disclosure for a Sustainable Development: An Australian Study

Addressing environmental, social and governance (ESG) issues has become a critical part of business strategy. This article explores the extent of ESG reporting of metal and mining sector companies listed in the Australian Securities Exchange to determine the nature of ESG indicators in use in the sector. The current study argues that stakeholder engagement is the key to enhance company environmental policy and sustainable development. According to the results of this study, ESG reporting motives are highly influenced by reporting regulations. Given the diversity in reporting of ESG, comparability of ESG strategic performance is problematic. This study contributes towards developing an ESG disclosure index, which companies could use as a legitimacy tool that external stakeholders could use to reliably measure and compare the ESG performance of companies. It also reveals there is an increased demand for more empirical research on integration of sustainability into strategic planning process.

Trading Partners and Trading Volumes: Implementing the Helpman–Melitz–Rubinstein Model Empirically

Helpman, Melitz and Rubinstein [Quarterly Journal of Economics (2008) Vol. 123, pp. 441–487] (HMR) present a rich theoretical model to study the determinants of bilateral trade flows across countries. The model is then empirically implemented through a two‐stage estimation procedure. We argue that this estimation procedure is only valid under the strong distributional assumptions maintained in the article. Statistical tests using the HMR sample, however, clearly reject such assumptions. Moreover, we perform numerical experiments which show that the HMR two‐stage estimator is very sensitive to departures from the assumption of homoskedasticity. These findings cast doubts on any inference drawn from the empirical implementation of the HMR model.     

Factors Influencing Organic and Fair Trade Coffee Growers Level of Engagement with Cooperatives: The Case of Coffee Farmers in Mexico

We study the factors influencing the percentage of organic and fair trade certified coffee sold through a cooperative by growers of five cooperatives in Mexico. The percentage of coffee sold through the cooperative was used as a proxy of growers’ engagement with a cooperative. Using factor analysis and a fractional probit regression, we evaluated the proposition that the level of engagement can be explained by transaction cost economics, social norms and connections, and farmer and farm business characteristics. We found that farm size, uncertainty regarding cooperative time of payment to the members and cooperative commitment on price to be paid negatively influence the level of engagement. In contrast, asset specificity, relational commitment, and price have a positive impact on engagement. Our results may help cooperatives and policy makers to build strategies aiming to increase this level of engagement. This is relevant because lower grower engagement has been found to be positively correlated with weak performing cooperatives.     

Prepurchase financing pool: Revealing the IRR problem

Internal rate of return (IRR) is one of the most common and important indicators in investment analysis because it is often used by managers and practitioners as a decision-making criterion. Moreover, the IRR reflects the financial cost in financing decisions and it helps to answer the following question when comparing different financing alternatives: “Which loan is the cheapest?” Among the different types of loans in Brazil, there is a financial product called a prepurchase financing pool (PPFP) that is generally regarded as the best option for financing or loans. The objective of this article is to use the prepurchase financing pool to show the flaws of IRR in financial analysis. In particular, when IRR is used to evaluate the prepurchase financing pool, one finds problems of reliability regarding (i) existence, (ii) uniqueness, and (iii) economic interpretation of the rate. The results show that the prepurchase financing pool is relevant evidence that the IRR flaws are found in financial products.     

Exploring the customer's intention to switch firms: The role of customer‐related antecedents

This study examined the customer‐related antecedents of the customer's intention to switch firms. Customer citizenship behavior was a key element in this study. Scholars have extensively studied the antecedents of customer citizenship behavior. However, the way that customer citizenship behavior relates to other attitudinal variables and the intention to switch has scarcely been analyzed. The proposed hypotheses were verified using partial least squares variance‐based structural equation modeling applied to 947 users of beauty care service firms in five countries. The results suggest that customer citizenship behavior is an antecedent of satisfaction, trust, and attitudinal loyalty. Two of these variables influence customers’ intentions to abandon relationships with the service provider. The implications of these findings enhance managers’ and scholars’ understanding of the determinants of customers’ intentions to switch firms.     

The Big Family: Informal Financing of Small‐ and Medium‐Sized Businesses by Guanxi

Guanxi facilitates interaction between companies and people in Confucian societies. Does this type of social construct still play the key role, when the entrepreneurs live in Western societies? The objective of this article is to verify the impact of Guanxi on the capacity of small and medium‐sized businesses accessing financial resources informally. To this end, data collected from small Chinese entrepreneurs active in the principal business center of Brazil were used. From nonparametric tests, the results suggest that: (1) different levels of Guanxi allow small and medium‐sized businesses to access informal financial resources; (2) different types of informal financing are mostly used, or judged to be more significant, depending on the level of Guanxi of the entrepreneur in terms of parental and nonfamily ties; and (3) unlike the Western literature on the financial cycles of start‐ups, this type of informal financing can extend beyond the initial stage of the business. © 2014 Wiley Periodicals, Inc.
