The effects of fuel prices and vehicle sales on fuel‐saving technology adoption in passenger vehicles

Although economic theory suggests that both sales and fuel costs affect technology adoption by vehicle manufacturers, there is very little empirical evidence on either effect. We document a strong connection between a vehicle's sales and its energy efficiency. Using a demographics‐driven demand shifter to isolate demand‐side changes in sales, we find that a one standard deviation increase in sales raises efficiency by 0.2%, compared with a mean improvement rate of 1.4% per year between 1997 and 2013. Higher fuel prices also increase technology adoption directly by increasing willingness to pay for fuel cost savings. The results have two implications: manufacturers will continue to focus technological improvements on top selling vehicles; and fuel taxes will have larger effects on technology adoption than fuel economy standards and feebates.     

Energy benchmarking in support of low carbon hotels: Developments,challenges, and approaches in China

Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking.     

GROWTH AND VARIABILITY OF SCHOOL DISTRICT INCOME TAX REVENUES: IS TAX BASE DIVERSIFICATION A GOOD IDEA FOR SCHOOL FINANCING?

School districts in Ohio have the option of diversifying their revenue base by adopting income taxes. Using a panel of Ohio school districts that adopted a local income tax from 1990 to 2008, we find that revenues are procyclical and fluctuate only mildly. The estimated short‐ and long‐run income elasticity of school district income tax revenues is 1.05 and 1.04, respectively. We also find that the school district tax base fully adjusts to its long‐run equilibrium within 2 years. Finally, we show that school district income tax adoption does not provide more stability to total school district tax revenues in the short or the long run. (JEL H71, H75)     

OPTIONS TO THE REALM: A COST NEUTRAL PROPOSAL TO IMPROVE POLITICAL INCENTIVES

In this article, we draw on the literature on political property rights, political accountability, and strategic management and entrepreneurship to propose a cost neutral reform aimed at promoting long‐run economic prosperity. We propose replacing politicians' defined benefit pensions with a financial contract that is tied to economic performance. In particular, we propose a contract that pays out a lump sum to a politician 30 years after their election if real gross domestic product per capita is above some preset benchmark. Furthermore, we show that the contract can be priced such that it is cost neutral in terms of present value with a defined‐benefit pension. We argue that this contract provides a net benefit to society. (JEL D70, D72)

The economic burden of depression among adults with rheumatoid arthritis in the United States

Aims: Depression is the most frequent comorbidity reported among patients with rheumatoid arthritis (RA). Comorbid depression negatively impacts RA patients’ health-related quality-of-life, physical function, mental function, mortality, and experience of pain and symptom severity. The objective of this study was to assess healthcare utilization, expenditures, and work productivity among patients with RA with or without depression.

Materials and methods: Data from adult patients who had at least two visits each related to RA and depression over a 1-year period were extracted from the Truven Health MarketScan research databases. Outcomes comprised healthcare resource utilization, work productivity loss, and direct healthcare costs comparing patients with RA with depression (n?=?3,478) vs patients with RA without depression (n?=?43,222).

Results: Patients with RA and depression had a significantly greater relative risk of hospitalization and number of all-cause and RA-related hospitalizations, utilization of emergency services, days spent in the hospital, physician visits, and RA-related surgeries compared with RA patients without depression. Patients with RA and depression had a higher risk of and experienced more events and days of short-term disability compared with patients without depression. The incremental adjusted annual all-cause and RA-related direct costs were $8,488 (95% CI = $6,793–$10,223) and $578 (95% CI = –$98–$1,243), respectively, when comparing patients with RA and depression vs RA only.

Limitations: The current analysis is subject to the known limitations of retrospective studies based on administrative claims data.

Conclusions: This study suggested increased healthcare utilization, work productivity loss, and economic burden among RA patients due to comorbid depression. These findings emphasize the importance of managing depression and including depression as a factor when devising treatment algorithms for patients with RA.
