Technical efficiency analysis correcting for biases from observed and unobserved variables: an application to a natural resource management project

This article brings together the stochastic frontier framework with impact evaluation methodology to compare technical efficiency (TE) across treatment and control groups using cross-sectional data associated with the MARENA Program in Honduras. A matched group of beneficiaries and control farmers is determined using propensity score matching techniques to mitigate biases stemming from observed variables. In addition, possible self-selection arising from unobserved variables is addressed using a selectivity correction model for stochastic frontiers recently introduced by Greene (J Prod Anal 34:15?C24, 2010). The results reveal that average TE is consistently higher for beneficiary farmers than the control group while the presence of selectivity bias cannot be rejected. TE ranges from 0.67 to 0.75 for beneficiaries and from 0.40 to 0.65 for the control depending on whether biases were controlled or not. The TE gap between beneficiaries and control farmers decreases by implementing the matching technique and the sample selection framework decreases this gap even further. The analysis also suggests that beneficiaries do not only exhibit higher TE but also higher frontier output.     

Infant mortality: an insured population perspective

Many insurers offer life coverage to individuals during the first year of life. The policies tend to have small face values, but frequently contain premium waiver or additional purchase options. General population mortality is significantly higher at this age relative to older children and even middle-aged adults. This article presents the mortality experience of an insured cohort in which death occurred under 1 year of age. In summary, the insured population's mortality rate was significantly lower and the leading causes of death were different than the general population.     

Physician acquisition: what to avoid after the deal is complete

After a hospital acquires a physician practice, relations can become strained between the parties in any of four areas: Governance and decision making. Technology. Payment structures. Emotional factors related to the acquisition.     

Uncertainty and central bank transparency: A non-Bayesian approach

We use a non-Bayesian approach to uncertainty, where “ambiguity” is taken into account, in order to analyze the issue of central bank transparency, and we underline that the use of such an approach may greatly change the results. We reconsider a specific argument against transparency found in the literature. We show that, in the presence of ambiguity, the argument can become a case in favor of transparency, which seems more in accordance with some stylized facts. Reduced Knightian uncertainty associated with increased transparency can contribute to making transparency beneficial.     

Mexican national cross-border shopping: Exploration of retail tourism

This exploration of cross-border shopping by Mexican national shoppers at a regional discount outlet mall studies the: (1) economic impacts of their expenditures on the local and regional economies, and (2) activities they engage in while at the outlet malls and benefits received from shopping there. Spending by cross-border shoppers varied by accommodation type; hotels or motels/friends and family spent approximately $800 (U.S.) on clothing daily and condominiums/day visitors between $400 and $475 (U.S.). The multiplier for cross-border spending at the local level ranged from 1.27 to 1.45. Top cross-border shopper activities were shopping and buying, followed by eating, and visiting.     

Adoption rationales of new management practices

This study considers that multiple and diverse rationales, including rational, emotional and socially conditioned responses can influence the adoption of management practices. The study includes four case studies in order to subject the adoption rationales that Sturdy (2004) posits to empirical inquiry and to explore the impacts of these differing rationales on characteristics of the subsequent adoption. The findings show that five of the six rationales Sturdy proposes are empirically identifiable. The findings also suggest that, subject to the exploratory nature of the study, earlier adoption of management practices is associated with political and psychodynamic rationales, consistent with notions of being seen to adopt new ways of working. The findings also suggest that the political and dramaturgical rationales are associated with more rapid adoption due to influential individuals or groups acting as champions. Whilst Sturdy proposes his rationales as a simple list, the findings of this study suggest a more complex relationship between the rationales. The study contributes to the growing body of literature that addresses the important topic of management practices, particularly those that provide an expository consideration.     

A U.S. Manufacturing Strategy for the 21st Century: What Policies Yield National Sector Competitiveness?

The national debate over the fate of U.S. manufacturing is back, with some asking the question: Is manufacturing dead? However, the U.S. manufacturing sector has been making a surprising comeback and added jobs in 2010 and 2011 following 12 straight years of declines. Utilizing economic data, coupled with qualitative manufacturing industry information, offers a unique opportunity for the authors to present a pragmatic and strategic national manufacturing strategy based on the realities of a continually evolving R&D/high-technology-based U.S. manufacturing sector.     

Supply chain environmental investments in dynamic industries: Comparing investment and performance differences with static industries

Research linking investments in environmental practices to firm performance has matured over the past years. However, empirical research is still ambiguous on how and whether investments in environmental practices improve a plant's performance. We believe that contingency factors, especially the industry in which plants act has a significant role in the success of environmental investments. Using empirical data collected across a wide range of industries our results indicate that plants competing in dynamic industries such as apparel do on average invest less in supply chain environmental practices compared to plants in static industries. In addition, these environmental investments do not significantly improve operational performance in dynamic industries in terms of cost, quality, delivery and flexibility. However, in static industries environmental investments do significantly improve a plant's operational performance in terms of cost, quality and flexibility.     

Economics at the FTC: Drug and PBM Mergers and Drip Pricing

Economists at the Federal Trade Commission pursue the agency??s competition and consumer protection missions. In this year??s essay, in antitrust, we discuss two recent mergers that involved Rx drugs: First, we describe key elements of the inquiry into the Express Scripts/Medco transaction in the pharmacy benefit management industry. Next, we analyze a merger that involved drugs that are used to treat patent ductus arteriosus: a condition that affects premature babies. On the consumer protection side, we discuss a pricing strategy??drip pricing??that involves the release of price information about a multi-part product over time as the consumer goes through the purchase process.
