A comparison of treatment effects estimators using a structural model of AMI treatment choices and severity of illness information from hospital charts

We compare the performance of various matching estimators using a novel approach that is feasible in the absence of experimental data. We estimate a structural model of hospital choices and catheterization for Medicare heart attack victims using hospital chart data on patient heterogeneity. With the estimated structural parameters, we simulate data for which the treatment effect is known. We find that as measures of individual heterogeneity are added to the controls, matching estimators perform well. However, the estimators do a poor job recovering the true treatment effect when measures of individual heterogeneity are unavailable. Copyright © 2010 John Wiley & Sons, Ltd.     

An Input–Output Analysis of the Nonprofit Sector in the USA and Germany

This paper presents an exploratory input–output analysis of the nonprofit sectors in former West Germany and the USA based on the conceptual and data structure provided by the System of National Accounts. When compared with the USA, the West German nonprofit sector catered more to government demands. A higher proportion of West German nonprofit services went to government and a smaller proportion went to households. In terms of the multiplier effect of nonprofit output, we find that an additional dollar of nonprofit services delivered to households and/or government induced indirectly an additional 83 cents of business output in the USA. By comparison, West Germany's nonprofit sector had a lower multiplier effect, with 43 Pfennig per DM1. We also find that businesses have a much larger stake in nonprofit production as intermediate suppliers when compared to their role as intermediate consumers. The economic position the nonprofit sector occupies in both countries is that of a producing sector, taking inputs from businesses and providing outputs for households and governments. This general structural characteristic suggests that the nonprofit sector is particularly sensitive to changes in government policies as well as to shifts in private household incomes, yet relatively insensitive to demand changes in other industries.

Managerial perspectives on drivers for and barriers to sustainable supply chain management implementation: Evidence from New Zealand

The purpose of this paper is to examine the factors that drive or prevent companies' implementation of sustainable supply chain management (SSCM) practices. To this end, we interviewed 29 senior managers from 23 New Zealand‐based companies. The key reported drivers were customer expectation, top management commitment, moral and ethical values of managers, reputation management, and economic and operational benefits. Conversely, cost concerns, strategic and structural restraints, supplier and customer issues, and a lack of effective regulations were cited as critical obstacles to SSCM implementation. Thus, the evidence from our findings provides support for both instrumental and normative logics for SSCM implementation. The findings further indicate that, in general, instrumental and normative logics are congruent; however, varied tensions arise when managers seek to simultaneously address competing yet desirable SSCM aspects. Accordingly, we argue that it is imperative to understand, work through, and manage such tensions as balancing divergent sustainability aspects holds considerable potential for successful SSCM implementation.     

Fiscal Rules and Financial Systems: Complements or Substitutes?

We study the effect of fiscal rules on a country's credit rating and their interaction with financial development. We build a rich set of panel data, which includes a novel index for the strength of fiscal rules. We find a positive and significant effect of fiscal rules on sovereign ratings. We also find that this effect is attenuated in economies with a more developed domestic financial system. Therefore, financial markets act as a substitute for fiscal rules in lowering the default risk assessed by credit rating agencies. This substitution effect between fiscal rules and financial development is mostly triggered through the monitoring and enforcement dimension of fiscal rules.     

Transfer Pricing and Ownership Structure

We study the performance of jointly owned production units where upstream firms sell inputs to a downstream final market producer. It is found that, compared to integrated firms, co-ownership leads to overinvoicing of input prices (transfer prices), resulting in lower aggregate profits. Tax and tariff policy may lessen the organizational inefficiencies of jointly owned firms. The analysis suggests that firms must have other reasons for forming jointly owned production units than those guided by production efficiency and benefits from delegation of decision-making.

Residential Enclosure,Power and Relationality: Rethinking Sociopolitical Relations in Southeast Asian Cities

As in many other areas around the globe, enclosed residential spaces have proliferated in Southeast Asia since the 1990s. Recent publications have presented such gated communities as ‘porous enclaves', implying multiple socio‐spatial dynamics of movements through gates and walls. However, the enclave model does not suffice for analyzing the relational dynamics generated by enclosed residential estates. The concept of ‘ecotonal space' and social geography are used to show, in the case of Cambodia's capital Phnom Penh, that the enclosure and its borders are producers and products of multiple social, spatial, economic and political relations, both symbolic and material. Property developers assert their position as an emerging elite in the city's society and politics, a process based on different types of everyday relations they have with the inhabitants of their residential estates and territorial institutions. The enclosed residential estate can serve as a resource for deploying new power relations. Consubstantial with the neopatrimonial nature of the Cambodian economy and politics, this process is a response to the opacity and uncertainty of real estate markets and urban development.     

What does IT Take for Congress to Enact Good Policies? an Analysis of Roll Call Voting in the US Congress

We study the conditions under which members of Congress incorporate policy‐specific considerations in their decisions. To do this, we estimate a model that accounts for the influence of private information about legislation quality on voting patterns in the House and Senate. We find that minority party members are more likely to evaluate proposals on their merits than majority members, but institutional and electoral considerations significantly attenuate these partisan differences. In particular, seniority, electoral safety, and constituents' political knowledge have a balancing effect on partisan predispositions to rely on policy‐relevant information, making minority (majority) members less (more) likely to vote informatively.
