In June 2005, a questionnaire survey was sent to 9000 companies in the Kansai Area (Osaka, Kyoto and Hyogo), the second largest economic block in Japan, with 2041 companies responding. This article introduces the results of this questionnaire survey. The greatest feature of this study is that,...

The almost continuous stagnation of the Japanese economy for the past two decades has had an adverse impact on Japanese households from at least three perspectives: A decline in the standard of living, an increase in risks and uncertainties relating to livelihood, employment, old age, etc., and...

We study how high-frequency traders (HFTs) strategically decide their speed level in a market with a random speed bump. If HFTs recognize the market impact of their speed decision, they perceive a wider bid-ask spread as an endogenous upward-sloping cost of being faster. We find that the speed...

In a second-price sequential auction with both global and local bidders, we explore the optimal order for selling heterogeneous goods to maximize efficiency or revenue. Our findings indicate that selling the good with very small variance (almost-zero variance) first yields higher revenue, while...

We study a signaling game where agents signal their type by choosing when to quit pursuing an uncertain project. High types observe news about project quality and quit when bad news arrives. This creates opportunities for low types who do not observe any news to mimic high types by quitting...

We consider the economy consisting of n agents and m heterogenous objects where the seller benefits v from objects. Our study focuses on the multi-object allocation problem with monetary transfers where each agent obtains at most one object (unit-demand). In the situation with arbitrary n, m and...

We consider the problem of allocating multiple units of an indivisible object among a set of agents and collecting payments. Each agent can receive multiple units of the object, and has a (possibly) non-quasi-linear preference on the set of (consumption) bundles. We assume that preferences...

The class of double-crossing preferences, where signaling is cheaper for higher types than for lower types at low signaling levels and the opposite is true at high signaling levels, underlines the phenomenon of countersignaling. We show that under the D1 refinement, the equilibrium signaling...

Each agent in a market needs to supplement his skill with a particular skill of another agent to complete his project. A platform matches the agents and allows members of the same match to share their skills. A match is valuable to an agent if he is matched with any agent who possesses a skill...
