Prompt K_short production in pp collisions at sqrt(s)=0.9 TeV

The production of K_short mesons in pp collisions at a centre-of-mass energy of 0.9 TeV is studied with the LHCb detector at the Large Hadron Collider. The luminosity of the analysed sample is determined using a novel technique, involving measurements of the beam currents, sizes and positions, and is found to be 6.8 +/- 1.0 microbarn^-1. The differential prompt K_short production cross-section is measured as a function of the K_short transverse momentum and rapidity in the region 0 < pT < 1.6 GeV/c and 2.5 < y < 4.0. The data are found to be in reasonable agreement with previous measurements and generator expectations.Comment: 6+18 pages, 6 figures, updated author lis

Do Foreign-Owned Firms Provide Better Working Conditions Than Their Domestic Counterparts? A Comparative Analysis

This paper analyses to what extent working conditions in foreign-owned firms differ from those in their domestic counterparts. It makes three main contributions. First, we replicate the consensus in the empirical literature by applying a standardised methodology to firm-level data for three developed (Germany, Portugal, UK) and two emerging economies (Brazil, Indonesia). We show that, consistent with previous evidence, foreign-owned firms offer substantially higher average wages than domestic firms and that this difference is particularly important in emerging economies. Second, we show that these positive wage effects of foreign takeovers reduce in size when controlling for changes in the composition of the workforce, although they tend to remain positive and statistically significant. However, the wage effects associated with worker movements from domestic to foreign firms are potentially important, particularly in emerging economies. Third, we look not only at wage outcomes but also consider other working conditions such as working hours, job stability and union coverage. We find that foreign takeovers of domestic firms tend to have a small positive effect on wages, but little effect on other aspects of working conditions

Measurement of sigma (pp -> bbX) at √s=7 TeV in the forward region

Decays of b hadrons into final states containing a D-0 meson and a muon are used to measure the bb; production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In the pseudorapidity interval 2 < eta < 6 and integrated over all transverse momenta we find that the average cross-section to produce b-flavoured or b-flavoured hadrons is (75.3 +/- 5.4 +/- 13.0) mu b

Capital accumulation and fiscal policy in an OLG model with family altruism

The idea of family altruism is that parents care only about their children's income and not about the use of this income made by the children. First, we establish dynamical properties which place the OLG model with family altruism halfway between the model with pure life-cyclers (Diamond (1965)) and the one with dynastic altruism (Barro (1974)). Then, we show that this concept leads to interesting fiscal policy conclusions less clear-cut and more realistic than those obtained with the two previous standard OLG models: a pay as you go social security is neutral but not a public debt

Institutions, deindustrialization, and functional income distribution in Japan

We investigate the long-term drivers of the labor share in Japan using data from the Japanese Industrial Productivity database from 1970 to 2012. The descriptive and econometric results indicate that the decline in the labor share observed in Japan during the period of analysis was highly concentrated in the low-knowledge-intensity sectors, the employment share of which has increased remarkably. These sectors also experienced a strong increase in non-regular workers, who constitute a secondary segment of the labor market in Japan, characterized by low wages and very limited union coverage. The low level of protection of this group of workers and the increase in market power concentration have probably contributed to reducing the bargaining power of labor vis-à-vis employers and, consequently, the labor share
