This paper investigates whether Japanese people were happy and unhappy with the general election conducted on September 11, 2005, in which the Prime Minister, Koizumi, won a landslide victory. We conducted a large survey just after the election to ask people how happy they were and which party...

This paper investigates whether the Japanese voters became happy and/or unhappy due to the results of the General Election in 2009. We conducted a daily web survey for seven days before and after the election, obtaining 1068 responses. Estimating a fixed effects model, we found that supporters...

We study deterministic voting mechanisms by considering an ordinal notion of Bayesian incentive compatibility (OBIC). If the beliefs of agents are independent and generic, we show that any OBIC mechanism is dominant strategy incentive compatible under an additional mild requirement. Our result...

This paper studies the interplay between climate, health, and the economy in a stylized world with four heterogeneous regions, labeled ‘West' (cold and rich), ‘China' (cold and poor), ‘India' (warm and poor), and ‘Africa' (warm and very poor). We introduce health impacts into a simple...

We propose a model of parental altruism in relation to children’s habit formation, as children are unaware of their developing habits while young and only become cognizant with age. We show that an altruistic mother (1) maintains the amount of income transferred to her child lower than the...

Using a monthly survey, this paper finds that supporters of the governing cabinet are significantly happier than non-supporters throughout our sample period. We investigate the reason and examine two hypotheses: 1) happy persons support the ruling Liberal Democratic Party, and 2) supporters of...

We analyze a dynamic principal-agent problem in which the agent's effort in each period has strong persistent effects. We show that a simple contract, where the reward depends only on the final outcome, is explained as the optimal contract derived in the principal's optimization problem. The...

There is a divisible commodity and money. Each agent has an endowment of the two goods and continuous, monotone, convex preferences over bundles. Agents may benefit from trade. An exchange rule is a mapping that, for each profile of preferences, calculates for each agent a trade that he finds...

This paper studies the problem of a monopolist who sells a network good through a price posting scheme. The scheme posts a price of every possible allocation for each buyer, who are then asked to report their private information to the seller. The seller then implements the allocation based on...
