People often tacitly assume an egocentric perspective when describing spatial scenes, and then use ambiguous descriptions (e.g., “The bottle is on the left.”).

What is a fiscal consequence of legislative term limits? We develop a legislative bargaining model that predicts a u-shaped relationship between the level of seniority within a legislature and government spending. The size of government spending decreases as the level of seniority increases from low tomoderate, while it increases as the level of seniority increases from moderate to high. The mo...
