Globalization, aggregate productivity, and inflation

This paper investigates the effects of globalization on aggregate productivity, output growth, and inflation. I present a simple two-country, two-good, flexible exchange rate model using Fisher Ideal aggregators to examine changes in the mapping from microeconomic to macroeconomic productivity growth as nations globalize. Advances in industry-specific labor productivity are shown to have potentially a much greater pass-through to aggregate productivity, output, and prices the more open nations are to trade. Globalization raises both the level and growth rate of aggregate productivity by allowing more economywide reorganization in response to ongoing technological advances than would be optimal otherwise. ; I develop a globalized version of the quantity equation of money, where inflation in the home country depends on domestic money growth and a weighted average of home and foreign GDP growth. Relative country size, consumer preferences, production technologies, and the openness of trade are the chief determinants of these weights. Calibrating the model to match certain stylized facts about the U.S. and global economies, U.S. consumer price inflation falls from roughly 3.8 percent when economies are closed to under 2 percent in the transition period, eventually settling at around 2.3 percent in free trade. Producer and consumer prices trek a common path under autarky but diverge as the world globalizes. Both home and foreign aggregate productivity growth rates increase—by 0.4 and 0.7 percentage points, respectively. Roughly 30 percent of the output weight in the determination of home inflation shifts from the home to the foreign economy—greater than might be expected from strong home bias.Globalization ; Inflation (Finance) ; Microeconomics ; Macroeconomics ; Gross domestic product

The Multi-Dimensional Nature of Wind Shear Investigations

The impact of air carrier accidents has lead to investigations into the wind shear phenomenon. This report includes such topics as wind shear characterization, aircraft pilot performance in shear conditions, terminology and language development, wind shear forecasting, ground and flight wind shear displays, wind shear data collection and dissemination, and pilot factors associated with wind shear encounters. Some areas which show promise for short term solutions to the wind shear hazards includes: (1) improved gust front warning through ground based sensors; (2) greater pilot awareness of wind shear through improved training; and (3) airborne displays based on groundspeed/airspeed comparisons

Electrical phase angle as a new method to measure fish condition

In this study, phase angle (the ratio of resistance and reactance of tissue to applied electrical current) is presented as a possible new method to measure fish condition. Condition indices for fish have historically been based on simple weight-at-length relationships, or on costly and timeconsuming laboratory procedures that measure specific physiological parameters. Phase angle is introduced to combine the simplicity of a quick field-based measurement with the specificity of laboratory analysis by directly measuring extra- and intracellular water distribution within an organism, which is indicative of its condition. Phase angle, which can be measured in the field or laboratory in the time it takes to measure length and weight, was measured in six species of fish at different states (e.g., fed vs. fasted, and postmortem) and under different environmental treatments (wild vs. hatchery, winter vs. spring). Phase angle reflected different states of condition. Phase angles 15° indicated fish that were in better condition. Phase angle was slightly affected by temperatures (slope = – 0.19) in the 0–8°C range and did not change in fish placed on ice for <12 hours. Phase angle also decreased over time in postmortem fish because of cell membrane degradation and subsequent water movement from intra- to extracellular (interstitial) spaces. Phase angle also reflected condition of specific anatomical locations within the fish
