Safeguarding livelihoods against reductions in economic output

Secular stagnation, escalating socio-ecological crises, and the urgent need to scale back resource use in affluent countries make reductions in economic output increasingly likely. In this context, the prevailing vulnerability of livelihoods to a reduction in output poses a fundamental threat, and obstructs stringent environmental policies that reduce production or consumption. This study explores what creates this vulnerability, and how it might be overcome. We introduce a novel analytic framework that describes the relationship between economic output and the adequacy of livelihoods. Using empirical data for the years around the Global Financial Crisis, we illustrate the vulnerability of livelihoods in the UK. Based on our framework, we show that the vulnerability is not inevitable but arises when livelihoods are dependent on wage labour whilst employment and adequate incomes for workers are insecure, or when adequate pensions are insecure. These conditions are pervasive in contemporary capitalist economies, primarily due to profit maximisation and neoliberal welfare and labour policy. Profit maximisation may in fact actively foster the vulnerability of livelihoods, as the vulnerability can be used as a lever for squeezing wages, and as a pretext for pursuing economic growth and blocking environmental policies. Finally, we identify a range of interventions that could overcome the vulnerability, including specific versions of universal basic services, a universal basic income, a minimum income guarantee, a job guarantee, living wages, worktime reduction, and a pension guarantee, alongside changes in capital-labour relations and a shift to not-for-profit provisioning. Such interventions could secure livelihoods in volatile or contracting economies, and make stringent environmental policies socially sustainable and more politically palatable

Luxury-focused carbon taxation improves fairness of climate policy

Equitable climate policies are required for a just and rapid energy transition. A widely discussed climate policy instrument is carbon taxes. Previous studies of the distributional implications of carbon taxation focused on uniform carbon taxes across sectors. Differentiated tax rates across goods and services received less attention. Here we model an alternative carbon tax design accounting for the distribution of household consumption and carbon footprints across 88 countries covering the global north and south. The policy distinguishes luxury and basic consumption and sets higher carbon prices for luxury. The policy reduces yearly global household emissions by 6% compared with no policy and inequalities are reduced compared with no policy and compared with a uniform carbon tax. By 2050, the policy saves around 100 gigatonnes carbon dioxide equivalents, which is 75% of what is needed for households to remain within a 2° consistent climate pathway

Limit on Bs0B^0_s oscillation using a jet charge method

A lower limit is set on the B_{s}^{0} meson oscillation parameter \Delta m_{s} using data collected from 1991 to 1994 by the ALEPH detector. Events with a high transverse momentum lepton and a reconstructed secondary vertex are used. The high transverse momentum leptons are produced mainly by b hadron decays, and the sign of the lepton indicates the particle/antiparticle final state in decays of neutral B mesons. The initial state is determined by a jet charge technique using both sides of the event. A maximum likelihood method is used to set a lower limit of \, \Delta m_{s}. The 95\% confidence level lower limit on \Delta m_s ranges between 5.2 and 6.5(\hbar/c^{2})~ps^{-1} when the fraction of b quarks from Z^0 decays that form B_{s}^{0} mesons is varied from 8\% to 16\%. Assuming that the B_{s}^{0} fraction is 12\%, the lower limit would be \Delta m_{s} 6.1(\hbar/c^{2})~ps^{-1} at 95\% confidence level. For x_s = \Delta m_s \, \tau_{B_s}, this limit also gives x_s 8.8 using the B_{s}^{0} lifetime of \tau_{B_s} = 1.55 \pm 0.11~ps and shifting the central value of \tau_{B_s} down by 1\sigma

Measurement of the Bs0^0_s lifetime and production rate with Ds−l+^-_s l^+ combinations in Z decays

The lifetime of the \bs meson is measured in approximately 3 million hadronic Z decays accumulated using the ALEPH detector at LEP from 1991 to 1994. Seven different \ds decay modes were reconstructed and combined with an opposite sign lepton as evidence of semileptonic \bs decays. Two hundred and eight \dsl candidates satisfy selection criteria designed to ensure precise proper time reconstruction and yield a measured \bs lifetime of \mbox{\result .} Using a larger, less constrained sample of events, the product branching ratio is measured to be \mbox{\pbrresult
