The Need for Speed: Impacts of Internet Connectivity on Firm Productivity

Fast internet access is widely considered to be a productivity-enhancing factor. Internet access speeds vary regionally within countries and even within cities. Despite articulate pleas for network upgrades to accelerate internet access, there is little rigorous research quantifying benefits to individual firms that arise from upgraded internet connectivity. We use a large New Zealand micro-survey of firms linked to unit record firm financial data to determine the impact that differing types of internet access have on firm productivity. Propensity score matching is used to control for factors, including the firm’s (lagged) productivity, that determine firms’ internet access choices. Having matched firms, we examine the productivity impacts that arise when a firm adopts different types (speeds) of internet connectivity. Broadband adoption is found to boost productivity but we find no productivity differences across broadband type. The results provide the first firm-level estimates internationally of the degree of productivity gains sourced from upgraded internet access.Internet, broadband, productivity

Ion laser plasmas

The typical noble gas ion laser plasma consists of a high-current-density glow discharge in a noble gas, in the presence of a magnetic field. Typical CW plasma conditions are current densities of 100 to 2000 A/cm^2, tube diameters of 1 to 10 mm, filling pressures of 0.1 to 1.0 torr, and an axial magnetic field of the order of 1000 G. Under these conditions the typical fractional ionization is about 2 percent and the electron temperature between 2 and 4 eV. Pulsed ion lasers typically use higher current densities and lower operating pressures. This paper discusses the properties of ion laser plasmas, in terms of both their external discharge parameters and their internal ion and excited state densities. The effect these properties have on laser operation is explained. Many interesting plasma effects, which are important in ion lasers, are given attention. Among these are discharge nonuniformity near tube constrictions, extremely high ion radial drift velocities, wall losses intermediate between ambipolar diffusion and free fall, gas pumping effects, and radiation trapping. The current status of ion laser technology is briefly reviewed
