Economic growth and the environment: Theory and facts

Several recent papers propose competing theoretical explanations for the empirical observation of an inverted U-shape relationship between environmental degradation and per-capita income. We propose the following test of the theory: calibrate a theoretical model to an already developed economy using information unrelated to the pollution–income curve. Then simulate the model starting from a less developed initial condition and compare the predicted pollution–income relationship with that in the data. Our results are mixed. Some support exists for the theory that the inverted U-shape results from a corner solution in which less developed countries do not abate pollution. However, because we find abatement is relatively inexpensive, the model predicts pollution peaks at a level of per capita income much lower than that observed in our U.S. data. For some pollutants, we find evidence of a structural break in preferences in the early 1970s. When the structural break is added, the model performs better for two of three pollutants.     

Ethical Problems, Conflicts and Beliefs of Small Business Professionals

This paper presents the results of a national study of the beliefs and perceptions of small business professionals concerning ethics within their company and business in general. The study examined their views on the relationship between success and ethical conduct as well as the extent and nature of ethical conflicts experienced by the respondents. Some comparisons are made with similar studies that have been conducted in the past. Respondents have the most ethical conflicts with customers and employees, and with regard to honesty in contracts/agreements. Most also believe that ethical standards are lower than they were 10 and 20 years ago, primarily because society's moral standards are lower. Additionally, they believe that the behavior of top management has the most influence on decisions in ethical situations. Finally, consistent with prior studies, they believe that they have the most responsibility to customers, ahead of employees and stockholders.     

Risk of major amputation or death among patients with critical limb ischemia initially treated with endovascular intervention,surgical bypass,minor amputation,or conservative management

Aims: Patients with critical limb ischemia (CLI) have an increased risk of major amputation. The initial treatment approach for CLI may significantly impact the subsequent risk of major amputation or death. The objective of this study was to describe the initial treatment approaches of patients with CLI and the limb outcomes associated with each approach.

Methods: Data from MarketScan Commercial and Medicare Supplemental Databases from January 2006–December 2014 was utilized. Cohorts of CLI patients were defined as follows: (1) peripheral vascular intervention (PVI); (2) peripheral vascular surgery (PVS); (3) minor amputation without concomitant PVI or PVS (MinAMP); and (4) Patients without PVI, PVS, or MinAMP (conservative therapy). The odds of major amputation or inpatient death were estimated using the Cox proportional hazards model. For those patients requiring a major amputation, the incremental expenditures per member per month (PMPM) were estimated using a gamma log-link model.

Results: Conservative therapy was associated with significantly higher odds of major amputation or inpatient death compared to patients who underwent minor amputation (1.59-times), PVI (2.08-times), or PVS (2.12-times). Patients treated with an initial strategy of minor amputation also had higher odds of major amputation or inpatient death compared to PVS (1.31-times) or PVI (1.33-times). The estimated incremental expenditures PMPM for patients with a major amputation was $5,165.

Conclusions: Revascularization reduces the risk of a major amputation or inpatient death for patients with CLI when compared to conservative therapy. Major amputation is also associated with significantly higher healthcare expenditures.     

Identity and social exclusion: an experiment with Hispanic immigrants in the U.S.

In this study we conduct a lab-in-the-field experiment with low-income Hispanics in three neighborhoods in a large city in the U.S. to investigate how identity and social exclusion influences individual contributions to fund local public goods. We find that while the strength of identity has a significant and positive impact on individual contributions to local public goods, the perception of social exclusion significantly decreases contributions. Our findings thus suggest factors that may impede full civic participation, and shed important light on potential policies to increase integration of immigrants and ethnic minorities into mainstream society.     

Food and beverage television advertising exposure and youth consumption,body mass index and adiposity outcomes

This study examines the relationships between exposure to food and beverage product television advertisements and consumption and obesity outcomes among youth. Individual‐level data on fast food and soft drink consumption and body mass index (BMI) for young adolescents from the Early Childhood Longitudinal Study, kindergarten cohort, (1998–1999) and adiposity measures for children from the US National Health and Nutrition Examination Survey (2003–2004) were combined with designated market area (DMA) Nielsen media advertising ratings data. To account for unobserved individual‐level and DMA‐level heterogeneity, various fixed‐ and random‐effects models were estimated. The results showed that exposure to soft drink and sugar‐sweetened beverage (SSB) advertisements is economically and statistically significantly associated with higher frequency of soft drink consumption among youth even after controlling for unobserved heterogeneity, with elasticity estimates ranging from 0.4 to 0.5. The association between fast food advertising exposure and fast food consumption disappeared once we controlled for unobservables. Exposure to cereal advertising was significantly associated with young adolescents' BMI percentile ranking, but exposures to fast food and soft drink advertisements were not. The results on adiposity outcomes revealed that children's exposure to cereal advertising was associated with both percent body fatness and percent trunk fatness; fast food advertising was significantly associated with percent trunk fatness and marginally significantly associated with percent body fatness; and exposure to SSB advertising was marginally significantly associated with percent body and trunk fatness. The study results suggest that continued monitoring of advertising is important and policy debates regarding the regulation of youth‐directed marketing are warranted.     

Should Cruise Ports Market Ecotourism? A Comparative Analysis of Passenger Spending Expectations within the Panama Canal Watershed

This study examined the expected spending patterns of cruise ship passengers as they debarked ships at ports within the Panama Canal Watershed. Results suggest that targeting marketing efforts toward ecotourism opportunities may increase long‐term ecological and economic benefits to port communities and local businesses. Most respondents were interested in ecotourism‐related activities in the Panama Canal Zone and nearby coastal areas. Furthermore, the ecotourism‐related market segments expected to spend significantly more money in port than conventional tourists. The growing ecotourism market represents an important opportunity for the cruise industry to partner with local ecotourism operators, enhancing profitability while simultaneously supporting sustainable development.

Intergovernmental Fiscal Arrangements and Provincial Consumption Risk Sharing in China

This paper utilizes a panel data set on two major fiscal reforms in China—the fiscal contract system (FCS) in 1980-93 and the tax-sharing system (TSS) after 1994—to examine how the various aspects of intergovernmental fiscal arrangement affect the ability of the fiscal system to facilitate risk sharing. The high revenue decentralization and the proliferation of extrabudgetary revenue items in the FCS generally weakened the central government's ability to support interprovincial risk sharing. This situation was reversed in the TSS period. In addition, the effect of central-to-local transfer (transfer-in) and local-to-central transfer (transfer-out) on risk sharing was asymmetric in the sense that transfer-out enhances risk sharing but transfer-in does not.     

Welfare effects of automatic-IRAs

Several states require employers who do not offer retirement benefits to automatically enroll their employees in individual retirement accounts (IRAs). We quantify the welfare effects of this program for individuals who follow a rule-of-thumb to make savings decisions. We find workers who save more than 3% would be willing to give up 0%–1.4% of lifetime consumption to avoid an IRA. We also consider a fully rational model with credit frictions, stochastic income and pre-retirement withdrawals, and costly IRA opt-outs. We find that being enrolled in an IRA is most likely to benefit workers who do not borrow during the life-cycle.     

DIS/POSSESSORY DATA POLITICS: From Tenant Screening to Anti-Eviction Organizing

In this article I place tenant screening data grabbing practices in tension with the ongoing work of housing justice-based tool making. While the tenant screening industry has spent decades amassing eviction data to facilitate the blocklisting of tenants with prior eviction records and thereby reifying racial capitalist geographies, housing organizers today rely on some of this same data to illuminate evictor networks and organize anti-eviction campaigns. This has been particularly important in the wake of corporate landlordism in which evictions are executed through opaque shell companies. Tenant-made tools attempt to undo this uneven landscape in which landlords own troves of data about tenants, but in which tenants don't even know their own landlords’ names. While opening up all eviction data to the public might appear to be an antidote, doing so can also provide screening companies with even more data to use in blocklisting. In my examination of this conjuncture, I forge the analytic of dis/possessory data politics to map out the violence of tenant screening data predation while also problematizing the technoliberal impulse to open up all eviction data. Yet dis/possessory data politics also attest to care and coalition work marked by practices of possession beyond logics of theft, banishment and techno solutionism.
