Structural Change, Competition and Job Turnover in the Swedish Manufacturing Industry 1964-96

The rate of inter-industry job turnover in Swedish manufacturing seems to be driven by the dispersion of profit changes among industries. Shifts in international competitiveness among industries played a central role for explaining this pattern. The rate of intra-industry job turnover among plants has been higher in industries with many small plants, low profit margins and high import penetration.Comparative advantage; market power; structural change; job turnover

Gamma Rays from Heavy Neutralino Dark Matter

We consider the gamma-ray spectrum from neutralino dark matter annihilations and show that internal bremsstrahlung of W pair final states gives a previously neglected source of photons at energies near the mass of the neutralino. For masses larger than about 1 TeV, and for present day detector resolutions, this results in a characteristic signal that may dominate not only over the continuous spectrum from W fragmentation, but also over the \gamma-\gamma and \gamma-Z line signals which are known to give large rates for heavy neutralinos. Observational prospects thus seem promising.Comment: 4 pages, 4 figures; revised to match published versio

Significant Gamma Lines from Inert Higgs Dark Matter

One way to unambiguously confirm the existence of particle dark matter and determine its mass would be to detect its annihilation into monochromatic gamma-rays in upcoming telescopes. One of the most minimal models for dark matter is the inert doublet model, obtained by adding another Higgs doublet with no direct coupling to fermions. For a mass between 40 and 80 GeV, the lightest of the new inert Higgs particles can give the correct cosmic abundance of cold dark matter in agreement with current observations. We show that for this scalar dark matter candidate, the annihilation signal of monochromatic \gamma\gamma and Z\gamma final states would be exceptionally strong. The energy range and rates for these gamma-ray line signals make them ideal to search for with the soon upcoming GLAST satellite.Comment: 4 pages, 3 figures; minor changes and text improvements; references updated; published versio

Silver-spoon upbringing improves early-life fitness but promotes reproductive ageing in a wild bird

Early-life conditions can have long-lasting effects and organisms that experience a poor start in life are often expected to age at a faster rate. Alternatively, individuals raised in high-quality environments can overinvest in early-reproduction resulting in rapid ageing. Here we use a long-term experimental manipulation of early-life conditions in a natural population of collared flycatchers (Ficedula albicollis), to show that females raised in a low-competition environment (artificially reduced broods) have higher early-life reproduction but lower late-life reproduction than females raised in high-competition environment (artificially increased broods). Reproductive success of high-competition females peaked in late-life, when low-competition females were already in steep reproductive decline and suffered from a higher mortality rate. Our results demonstrate that ‘silver-spoon’ natal conditions increase female early-life performance at the cost of faster reproductive ageing and increased late-life mortality. These findings demonstrate experimentally that natal environment shapes individual variation in reproductive and actuarial ageing in nature

The Effect of Customer Information during New Product Development on Profits from Goods and Services

Purpose – This study aims to investigate how customer information obtained at different phases of a new product development (NPD) process influences profits from new offerings. Design/methodology/approach – A survey was conducted in the context of NPD in goods and services. A unique database was constructed that merged key informant survey responses with financial data for 244 firms. This database was used to replicate and extend previous research by posing a number of hypotheses regarding the role of obtaining customer information in NPD. Findings – The results show that obtaining customer information during NPD influences the profits from new offerings, which vary depending on the phase of the NPD process. The financial rewards from obtaining customer information for goods are highest in the early phases of the NPD process and decline in later phases. The financial rewards for services, on the other hand, are high in the early and late phases of the NPD process. Research limitations/implications – The research is based on a survey combined with objective financial data, that is, a combination of different data sources. The research would have benefitted from longer data series and a higher response rate. Originality/value – This study replicates and extends previous research by testing the role of obtaining customer information in both manufacturing and service firms by combining survey data with objective financial data

The Invisible Power of MacHines Revisiting the Proposed Flash Order Ban in the Wake of the Flash Crash

Technological innovation continues to make trading and markets more efficient, generally benefitting market participants and the investing public. But flash trading, a practice that evolved from high-frequency trading, benefits only a select few sophisticated traders and institutions with the resources necessary to view and respond to flashed orders. This practice undermines the basic principles of fairness and transparency in securities regulation, exacerbates information asymmetries and harms investor confidence. This iBrief revisits the Securities and Exchange Commission\u27s proposed ban on the controversial practice of flash trading and urges the Securities and Exchange Commission and the Commodity Futures Trading Commission to implement the ban across the securities and futures markets. Banning flash trading will not impact high-frequency trading or other advantageous innovative trading practices, and will benefit all market participants by making prices and liquidity more transparent. In the wake of the May 6, 2010 flash crash and the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act, now is an opportune time for the Securities and Exchange Commission and Commodity Futures Trading Commission to implement the ban
