Brain-computer interfaces (BCI) are communication systems that allow people to send messages or commands without movement. BCIs rely on different types of signals in the electroencephalogram (EEG), typically P300s, steady-state visually evoked potentials (SSVEP), or event-related desynchronization. Early BCI systems were often evaluated with a selected(More)
This paper exploits the significant positive response of the share of agricultural value added and GDP per capita growth to variations in the international prices for agricultural commodities and rainfall to construct instrumental variables estimates of the causal effect that changes in the size of the agricultural sector and GDP per capita growth have on(More)

We use a rich dataset of regional government expenditures for Japan during the 1990-2000 period to estimate from within-prefecture variation the multiplier of government investment and government consumption expenditures. Our main finding is that government spending did not have multipliers effects that are on average larger than one. Government investment(More)
