Sequential Malmquist Indices of Productivity Growth: An Application to OECD Industrial Activities

The paper applies both the standard DEA methodology with contemporaneous frontiers and DEA with sequential frontiers to study changes in productivity and efficiency in manufacturing for a sample of eleven OECD countries over a twenty-year period. It uses a decomposition of the industrial Malmquist productivity indices to locate the sources of productivity growth: 'technical progress' and 'catching up.' The alternative indices are interrelated in a unifying framework that provides an interpretation to their difference. We argue that for manufacturing industries, in which technological regress is unlikely to occur, DEA with sequential frontiers provides a more adequate measure for the contribution of technical changes than standard DEA.     

A cost analysis of SIR-Spheres yttrium-90 resin microspheres versus tyrosine kinase inhibitors in the treatment of unresectable hepatocellular carcinoma in France,Italy, Spain and the UK

Abstract

Background and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).

Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.

Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).

Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent.     

All in the family or public? Law and appropriative costs as determinants of ownership structure

We examine how the legal protection of outside shareholders and the appropriative costs that they induce influence the incentives for private firms to go public. A higher degree of protection of shareholders can increase the appropriative costs associated with the conflict between managers and shareholders. To counteract this effect the managers/owners increase the share of the firm they retain so that, overall, higher protection of outsiders increases the likelihood of going public. In addition, we examine how the share of funds raised used to finance the firm affects both appropriative costs and the decision to sell.For helpful comments we thank participants at the conference on Corporate Governance at UC Irvine (February 2002), seminar participants at the Athens University of Economics and Business, and worskshop participants on the New Organization of Labour at the 2002 CESifo summer Institute in Venice.

Problems evaluating sales representative performance?: Try activity-based costing

Activity-based costing (ABC) offers a way to improve performance evaluation by providing estimates of the cost of satisfying sales terms to which a sales representative may agree, such as number of batches in which an order is produced and number of training hours provided to customer employees. It also provides estimates of the cost of resources that a sales representative may use while engaging in marketing activities, such as making sales calls and attending trade shows. Traditional costing, which assumes that costs only vary at the unit level, does not provide estimates of the costs of many of these terms and activities.     

Development and transformation of collaborative networks in events

This study examines the mechanisms by which and the reasons that leaders of non-profit organizations transform interorganizational collaborative networks through event attendance. Drawing from a two-wave survey, this study examines the interorganizational networks of 30 individuals who participated in both waves, along with the reported activities of 121 individuals who participated in the second wave of the survey. This mixed methods study found that events transformed participants’ weak ties into strong ties and promoted development of collaborative networks. Further, the study found that participants’ motivations for attending the event and following up with contacts afterward focused on sharing resources and deepening connections. Implications for understanding how events promote formation and transformation of collaborative networks are discussed.     

Moving markets? Government bond investors and microeconomic policy changes

Do sovereign bond markets react systematically to microeconomic policy reforms? Some observers suggest that investors are very attentive to supply‐side policies such as those related to labor markets, corporate taxation, and product standards. They argue that, along with macroeconomic outcomes and broad financial market conditions, such reforms affect sovereign bond premiums, for developed as well as emerging economies. In contrast, we predict few systematic effects of supply‐side policy reforms on sovereign bond market outcomes. Our theory draws on a standard three‐equation model of the economy, widely accepted among economic and finance professionals. That model makes few clear predictions regarding the anticipated effects of microeconomic policy changes; as a result, we expect that such reforms will not generate systematic market reactions. Our analyses, based on daily data from 37 countries from 2004 to 2012, indeed reveal little evidence of a systematic bond market reaction to the 47 most significant reforms to corporate taxation and labor market regulation. These results call into question the notion that “bond market vigilantes” play a central role in compelling governments to enact specific microeconomic policy changes.     

The fundraiser's journey: A developmentally informed,grounded theory analysis

Fundraisers play a vital role in the success of nonprofit organizations, yet relatively little is known about the experiences, motivations, and thought processes that inform their career choice and development. This exploratory, cross-comparative case study of 3 fundraisers addresses this gap in the literature by examining some formative influences on fundraisers' careers, their professional growth aspirations and opportunities, and how, if at all, they engage in personal philanthropy. Results suggest that fundraisers' aptitudes, skills, and abilities may influence their career choice more than a sense of connection to the nonprofit sector or organizational mission. Further, fundraisers seek opportunities to exercise leadership at the individual, organizational, and community levels. Additionally, their personal philanthropy and social embeddedness play integral roles in their professional development. Although not large enough for generalization, these results suggest the need to study fundraisers holistically, including their psychological development and social embeddedness over time. We argue for the need to move beyond traditional marketing and public relations perspectives to explain fundraising. Instead, future studies should adopt a service-dominant logic framing that considers fundraisers as part of a larger philanthropic ecosystem. We conclude with several questions to guide future studies toward this line of inquiry.
