We investigate multiunit exchange where a central planner and participants both bring commodities to sell and the central planner plays the role of platform provider. The central planner has restrictions on allocations. We characterize the optimal mechanism concerning his (her) revenue under...

In estimation of parameters in restricted spaces, several interesting and surprising results have been developed from a decision-theoretic point of view. For instance, in estimation of a normal mean with a known variance, the sample mean is minimax in the case that the mean is bounded from one...

This paper shows that new economic geography models are capable of simulating the real-world tendency for urban agglomeration to the primate city. It is often observed that while regional populations were dispersed in early times, they have been increasingly concentrated into one capital region...

This paper proposes a simple econometric framework that can identify moral hazard and selection problems separately in insurance markets. Although our methodology requires behavioral assumptions on the consumer's optimization, we show that these assumptions are necessary for the separate...

Both Japan in the late 1980s and the U.S. in the mid-2000s experienced an unsustainable boom in real estate prices along with high stock market valuations, and when the bubble burst, many households and financial institutions found themselves in dire straits. One major lesson from this...

The Henry George Theorem (HGT), or the golden rule of local public finance, states that, in first-best economies, the fiscal surplus, defined as aggregate land rents minus aggregate losses from increasing returns to scale activities, is zero at optimal city sizes. We derive a general second-best...

In this paper, we investigate equilibrium cycles in dynamic general equilibrium models with cash-in-advance constraints. Our findings are two-fold. First, in such models, if an equilibrium cycle exists, then there also exists a continuum of equilibrium cycles in its neighborhood. Second, the...

The Japanese aircraft industry, which operated on a very small scale before World War II, became Japan's largest manufacturing industry by the end of the war. In this paper, we explore the causes of the growth of the aircraft industry during this time by focusing on the No. 5 Works of Mitsubishi...

This paper compares the three recent episodes of boom and bust cycles in asset prices: Japan in the late 1980s to the 1990s; the U.S. since the mid 1990s; and China during the last decade. Although we have not yet seen a collapse of Chinese property prices, the increases so far are comparable to...

This paper offers a brief summary of non-traditional monetary policy measures adopted by the Bank of Japan (BOJ) during the last two decades, especially the period 1998-2006, when the so-called Zero Interest Rate Policy (ZIRP) and Quantitative Easing (QE) were put in place. The paper begins with...
