Note – Walking on Solid Ground: A Replication Study of ‘Housing Health and Happiness’

This note summarises our replication study ‘Housing, Health, and Happiness’, henceforth HHH2009, which constitutes an important paper in the literature of housing and slum upgrading. The original authors conduct a quasi-experimental impact evaluation of ‘Piso Firme’, an intervention that replaced in-house dirt floors with cement in Mexico. We conduct a Pure Replication (PR), a Measurement and Estimation Analysis (MEA), and a Theory of Change Analysis (TCA). In our PR, we did not find any major discrepancy with the original study. In the MEA, we generally find the results to be strongly robust to different types of alternative analysis. Finally, in TCA we explore a dimension that was not reported on the published version of the study and found that households with high initial levels of cement-floor coverage benefitted significantly less from Piso Firme’s intervention. These findings are discussed in greater detail on International Initiative for Impact Evaluation’s (3ie) working paper version.     

Varieties of Radicalism: Examining the Diversity of Radical Left Parties and Voters in Western Europe

Radical left parties (RLPs) are diverse and several RLP subtypes have been distinguished in the literature. However, the degree to which these subtypes are linked to significantly different policy proposals has not been analysed, and little is known about whether subtypes are associated with differences in their respective voters’ characteristics. This article analyses the policy positions of RLPs across a number of issues, using manifesto and expert survey data, allowing insights into the differentiation between types of RLPs. RLPs differ in the extent to which they adopt New Politics issues, and the article proposes a classification of Traditional and New Left RLPs. Using cross-national survey data from the European Election Studies series and multilevel multinomial models, the article examines the ideological, policy and social differences in the electorates of the various types of RLPs. It finds socio-demographic and attitudinal differences between the voters of Traditional and New Left RLPs that are consistent with the programmatic differences of the parties.     

The Role of Immigration: Race/Ethnicity and San Diego Homicides Since 1970

Objectives

The temporal variation in homicide is examined by studying trends in race/ethnic specific killings (e.g. Blacks, Latinos and Whites). Two substantively important issues are also addressed—a closer examination of the role community heterogeneity plays in homicide levels and the treatment of immigration as an endogenous social process.

Methods

Data are reported homicides in the city of San Diego, California over the period 1960–2010. The address of each killing is geocoded into 341 census tracts.

Results

We find that neighborhoods experiencing increases in the foreign-born population tend to be less violent. White and Latino homicide victimization was reduced significantly as a product of increases in the neighborhood concentration of foreign-born individuals. Supplementary analyses did not find empirical evidence that the influx of foreign-born individuals could (or should) be considered a disruptive social process. Over the past five decennial census periods, the exponential increase in immigration in this border city is not associated with an increase in homicide victimization.

Conclusions

When examined through a wider temporal lens than is typically employed, and accounting for the endogeneity of immigrant residential settlement, we find no support for the claims that immigration is a crime generating social process.

     

Self‐Organizing Policy Networks: Risk,Partner Selection,and Cooperation in Estuaries

Policy actors seek network contacts to improve individual payoffs in the institutional collective action dilemmas endemic to fragmented policy arenas. The risk hypothesis argues that actors seek bridging relationships (well‐connected, popular partners that maximize their access to information) when cooperation involves low risks, but seek bonding relationships (transitive, reciprocal relationships that maximize credibility) when risks of defection increase. We test this hypothesis in newly developing policy arenas expected to favor relationships that resolve low‐risk dilemmas. A stochastic actor‐based model for network evolution estimated with survey data from 1999 and 2001 in 10 U.S. estuaries finds that actors do tend to select popular actors as partners, which presumably creates a centralized bridging structure capable of efficient information transmission for coordinating policies even without any government mandate. Actors also seek reciprocal bonding relationships supportive of small joint projects and quickly learn whether or not to trust their partners.     

The Origins of Conflict in Polycentric Governance Systems

Natural resources are governed by polycentric systems, which can be conceptualized as an “ecology of games” in which policy actors participate in multiple policy forums governing interdependent issues. This article analyzes why actors perceive different payoffs across the forums in which they participate, ranging from mutually beneficial games of cooperation to conflictual zero-sum games in which one actor's gain means another actor's loss. The authors develop hypotheses at the level of the individual, the forum, and the overall polycentric system and test them using survey data collected in three research sites: Tampa Bay, Florida; the Paraná River delta, Argentina; and the Sacramento–San Joaquin River delta, California. The empirical findings suggest that levels of conflict in policy forums are higher when the actors who participate in them are concerned with hot-button issues, when the forums have large and diverse memberships, and in systems with a long history of conflict. The results shed new light on the drivers of conflict and cooperation in complex governance systems and suggest ways to manage conflict.     

Focusing Events and Changes in Ecologies of Policy Games: Evidence from the Paraná River Delta

Solving environmental problems on a regional scale demands joint efforts by multiple stakeholders, but coordinating such efforts can be difficult in complex governance systems. In this article, we combine the literature in Adaptive Governance with the Ecology of Policy Games (EPGs) framework to enhance our understanding of how complex governance systems react to environmental focusing events. We study the EPGs in the Paraná River delta in Argentina following widespread fires caused by slash‐and‐burn practices in 2008, and analyze how new forums created to address the consequences of this event differ from the forums created prior to the event in terms of their capacity to attract stakeholders and to provide higher interconnectivity to the whole governance system. Furthermore, we offer an initial evaluation of the Comprehensive Strategic Plan for the Conservation and Sustainability of the Paraná River delta, the main forum in the EPGs created to address the negative consequences of the focusing event. Finally, we discuss the implications of our findings for the study of complex governance systems where stakeholders are able to address the management of natural resources at a regional scale.     

University–Industry Linkage Framework to Identify Opportunity Areas

Although there are many studies of the collaboration between academia and industry in developed countries explaining the phenomenon and prescribing best practices, the findings cannot be extrapolated to developing countries. This article fills the gap by studying these interactions for the case of Mexico. To study these interactions, we performed a state‐of‐the‐art matrix analysis to obtain internal, structural, and environmental factors from literature. Then, an interpretative structural framework was built as a model to identify opportunities in the collaboration process. The results are presented in a map that describes how each element influences the others and highlights opportunities for improvement. The model shows that industry triggers collaboration and presents a highly complex internal organization for the academy. This study helps decision makers in government, the academy, and industry to understand the elements and how the system works to develop strategies that promote more effective collaboration.
