Abstract

Relative to the randomized controlled trial (RCT), the basic regression discontinuity (RD) design suffers from lower statistical power and lesser ability to generalize causal estimates away from the treatment eligibility cutoff. This chapter seeks to mitigate these limitations by adding an untreated outcome comparison function that is measured along all or most of the assignment variable. When added to the usual treated and untreated outcomes observed in the basic RD, a comparative RD (CRD) design results. One version of CRD adds a pretest measure of the study outcome (CRD-Pre); another adds posttest outcomes from a nonequivalent comparison group (CRD-CG). We describe how these designs can be used to identify unbiased causal effects away from the cutoff under the assumption that a common, stable functional form describes how untreated outcomes vary with the assignment variable, both in the basic RD and in the added outcomes data (pretests or a comparison group’s posttest). We then create the two CRD designs using data from the National Head Start Impact Study, a large-scale RCT. For both designs, we find that all untreated outcome functions are parallel, which lends support to CRD’s identifying assumptions. Our results also indicate that CRD-Pre and CRD-CG both yield impact estimates at the cutoff that have a similarly small bias as, but are more precise than, the basic RD’s impact estimates. In addition, both CRD designs produce estimates of impacts away from the cutoff that have relatively little bias compared to estimates of the same parameter from the RCT design. This common finding appears to be driven by two different mechanisms. In this instance of CRD-CG, potential untreated outcomes were likely independent of the assignment variable from the start. This was not the case with CRD-Pre. However, fitting a model using the observed pretests and untreated posttests to account for the initial dependence generated an accurate prediction of the missing counterfactual. The result was an unbiased causal estimate away from the cutoff, conditional on this successful prediction of the untreated outcomes of the treated.

Abstract

This article by Bolko von Oetinger, a senior vice president and director of the Strategy Institute for the Boston Consulting Group, is the first in a series of three articles that distill the ideas in the book, A Passion for Ideas: How Innovators Create the New and Shape Our World, edited by Heinrich von Pierer and von Oetinger (Purdue University Press, 2002). The book includes interviews with and articles by successful innovators from many areas: business, politics, the arts, the sciences, psychology, education, advertising, architecture, universities, and schools. Dr von Oetinger has blended comments from the experts with his own experience to offer five patterns of behavior needed for corporate innovation. This article provides many quotations from the book while presenting the first two behavioral patterns: (1) finding something new is not the problem; getting rid of the old presents the real threat; and (2) since innovation creates anxiety, you have to open up your organization

Abstract

My interest in public administration as a discipline was sparked by Dr Joseph P.L. Jiang, who was a student of the late Professor Fred W. Riggs at Indiana University, in 1968 when I took his course in public administration during my final year at the Department of Political Science, University of Singapore. I also remember fondly my first meeting with Professor Riggs during the same year when he gave a guest lecture in Dr Jiang's course (Quah, 2008d). I met Fred again many years later at various international conferences but I remember fondly our meetings in Chiangmai in June 1993 and in Honolulu in June 1996. I have also remained in touch with Dr Jiang after his return to Taipei.

Abstract

Purpose

This paper aims to examine the complexity of attribute configurations affecting tourism decisions related to peer-to-peer accommodation and the sharing economy in destinations affected by recession.

Design/methodology/approach

Based on chaos and complexity theories this non-parametric research examines the perspectives of 352 peer-to-peer accommodation holidaymakers in Athens, Greece. Using fuzzy-set qualitative comparative analysis (fsQCA), the study examines the complex relations between social and economic aspects, benefits, risks and consumer trust with regard to purchasing intentions. The paper also compares fsQCA with the dominant linear methods of analysis (regression; Cramer’s V) and highlights fsQCA’s suitability when dealing with tourism complexity.

Findings

The results reveal three configurations explaining the attributes of holidaymakers’ tourism decisions characterised by socio-economic orientation, trust formulation and price sensitivity. They also highlight the superiority of fsQCA towards conventional linear analyses in complexity aspects.

Research limitations/implications

The examination of the complexity concept using fsQCA can provide a better understanding of the influence of attributes which affect tourism decisions especially for countries suffering from deep recession such as Greece. Still, due to the lack of fsQCA implementation in tourism studies, its full potential needs to be further examined.

Originality/value

In terms of the literature, the study provides an understanding of the complexity formulation of tourism decisions during recession, with special focus on the sharing economy. It further explores the attributes that affect tourism decisions and associated linkages. Methodologically, the study highlights the value of fsQCA and its advantages compared to conventional methods of correlational analysis. It also progresses from fit to predictive validity for the models suggested.

Abstract

THE re‐organisation of local government in Greater London and the resultant amalgamation of library authorities is viewed by many with considerable misgivings. The upheaval of staff, the loss of status for some senior officers, the general uncertainty for the future—these are very real consequences of the Act and they cannot be ignored. Many chief librarians will see the work of a lifetime, perhaps spent in building up a comprehensive and unified system, made virtually meaningless overnight.

Abstract

THE luncheon given by the Lord Mayor, Sir Ralph Perring, to more than 700 guests at Guildhall on November 14, officially launched the country on National Productivity Year. Apart from representatives of the 120 local committees these were people from trade and employers' associations, trades unions, professional bodies and research organisations. It was, in effect, a token mobilisation of Britain's industrial might, because behind it stands a large army devoted to the task of increasing the country's output.

Abstract

Two linked topics concerning environmental issues at the WTO and their implications for MNEs are considered – namely, international business in the environmental goods and services sector, and the relationship of the WTO to the emerging climate change regime, particularly the Kyoto Protocol. Liberalization of barriers to international trade and investment in environmental goods and services could expand market access and otherwise change competitive conditions for multinational firms. The relationship of the WTO to the Kyoto Protocol is on the broader agenda of environmental and economic diplomacy. Decisions concerning these two sets of issues during the next few years will affect multinational firms’ competitive positions, strategies and operations in many industries. For instance, the liberalization of barriers to trade and FDI in the environmental goods and services industry creates new international market opportunities for firms that want to expand abroad; it also creates new competitive threats in home markets. The chapter was in press when the WTO Cancun ministerial meeting collapsed in mid-September 2003.
