“Bluewashing” the Firm? Voluntary Regulations,Program Design,and Member Compliance with the United Nations Global Compact

Voluntary programs have emerged as important instruments of public policy. We explore whether programs lacking monitoring and enforcement mechanisms can curb participants’ shirking with program obligations. Incentive‐based approaches to policy see monitoring and enforcement as essential to curb shirking, while norm‐based approaches view social mechanisms such as norms and learning as sufficient to serve this purpose. The United Nations Global Compact (UNGC), a prominent international voluntary program, encourages firms to adopt socially responsible policies. Its program design, however, relies primarily on norms and learning to mitigate shirking. Using a panel of roughly 3,000 U.S. firms from 2000 to 2010, and multiple approaches to address endogeneity and selection issues, we examine the effects of Compact membership on members’ human rights and environmental performance. We find that members fare worse than nonmembers on costly and fundamental performance dimensions, while showing improvements only in more superficial dimensions. Exploiting the lack of monitoring and enforcement, UNGC members are able to shirk: enjoying goodwill benefits of program membership without making costly changes to their human rights and environmental practices.     

Opportunities and competition in thick labor markets: Evidence from plant closures

Since Marshall (1890), it has been widely held in urban economic theory that cities insure workers against the risk of unemployment by offering a larger pool of potential jobs. Using a large administrative panel data set on workers displaced as a result of plant closures, we examine whether positive effects from a higher urban job density are offset by more intense competition between workers. When controlling for the sorting of workers between regions, we find robust evidence that the effect of job competition on unemployment duration exceeds that of job opportunities in absolute value. Our results put the idea of urban risk-sharing into perspective and provide an explanation for observed longer unemployment durations in cities.     

SLAVES IN BRONZE AGE SOUTHERN SCANDINAVIA?

The article proposes that unfree labour was an integral part of Bronze Age society. The presence of the unfree (thralls or even slaves) in prehistoric societies has rarely been discussed and never in the light of archaeological evidence. The article is based on empirical material from 333 fully excavated house remains from 120 sites in the Viborg area in northwest Jutland, Denmark. Based on the reconstructed size of these longhouses, the location of fireplaces, entrances and the subdivision of space, it is suggested that farmsteads, in general, had two, often clearly separated habitation units. In the Early Bronze Age, a longhouse was usually subdivided into two parts, and during the Late Bronze Age, this subdivision manifested in the construction of two longhouses. After a thorough analysis of the archaeological record, it is suggested that the owner of the land had occupied one habitation unit, while the other was reserved for the unfree.     

Sharpening Advocacy Coalitions

The concept of “advocacy coalitions” is the bedrock of the Advocacy Coalition Framework (ACF), one of the most established and successful approaches for understanding policy processes across the globe. This article revisits and sharpens the conceptual definition of advocacy coalitions. We summarize the lessons from its theoretical emphases under the ACF and specify its five attributes (policy actors, shared beliefs, coordination, resources, and stability). Through this specification, we identify the ideal coalition type and several coalition subtypes. We then clarify and make a distinction between how we think about coalitions as a concept and how we approach coalitions empirically. This article sharpens the lens for describing and explaining coalitions toward better observations, theorizing, and measurements. It ends with next steps for further deepening and broadening knowledge about advocacy coalitions.     

Horticulturists and oxygen ecozones in the tropical and subtropical forests of Southeast South America

We analyse the isotopic values (δ¹³C, δ¹⁵N) of the diet of pre-Columbian horticulturalist populations from tropical and subtropical areas of southeastern South America, belonging to the Guarani and Taquara archaeological units. The data indicate different trends in each one (T?=?4.21; P?=?0.0004), showing a mixed diet with maize consumption in the Guarani samples (δ¹³C_co?=??15.5?±?1.8‰; δ¹³C_ap ?10.4?±?0.8‰) and a depleted one in the Taquara ones (δ¹³C_co ?18.2?±?1.7‰; δ¹³C_ap ?11.9?±?0.9‰), with a significant internal dispersion in both populations. The first population has higher nitrogen values (δ¹⁵N 11.1?±?0.6‰) compared to the Taquara samples (δ¹⁵N 9.3?±?1‰), suggesting a more carnivorous diet. The recognition of these pre-Columbian mixed diets involves the identification of maize cultivation on the Atlantic side of the southernmost area of South America (Parana Delta, 34° SL). Through the analysis of δ¹⁸O we have identified two isotopic ecozones, the first along the Paraná River Valley, with an average value of δ¹⁸O ?3.7?±?0.5‰ (CV?=?13.5%; CI?=??3.83 / ?3.16), and the second one, located in the Planalto of southern Brazil (Araucaria Forest), with a mean value of δ¹⁸O ?1.5?±?0.3‰ (CV?=?16.5%; CI?=??1.69 / ?1.29). The isotopic data (δ¹³C, δ¹⁵N and δ¹⁸O) suggest human movements between these two ecozones.     

Neolithic and Bronze Age ungulate footprint-tracks of the Severn Estuary: Species,age, identification and the interpretation of husbandry practices

Ungulate footprint-tracks provide information regarding the species and age of animals. Combined with other datasets, this contributes to interpretation of seasonal husbandry patterns in the Severn Estuary, focusing on Bronze Age intertidal footprint-tracks at Redwick and Goldcliff East and the Late Neolithic site of Oldbury. Metric dimensions and morphology of modern contemporary ungulate footprint-tracks are used as analogues to help understand the species and age of prehistoric ungulates. Findings indicate that Dexter cattle and Soay sheep are metrically similar to British prehistoric ungulates. The prehistoric sites have a concentration of neonatal and juvenile individuals. Along with evidence provided by environmental data, faunal skeletal assemblages and lipid and isotopic analysis, this leads to the conclusion that the presence of younger animals and evidence at Brean Down for dairying is consistent with saltmarsh grazing activity in spring and summer.
