An important goal in quantitative risk/safety analysis of chemical toxins or pharmaceutical agents is determination of toxic risk posed by exposure to the agent.

This article investigates the effects of the securities transaction tax (STT) on market trading volume and return volatility using Chinese data. We found strong evidence to support a negative relationship between STT and market trading volume. The shrinking of the tax base casts doubt on the...

This paper reports a design and building process of a net-zero-energy modular house, named ElementHouse, which was entered for the 2007 Solar Decathlon competition that was organized by the U.S. Department of Energy. This paper discusses the development of the ElementHouse from its initial...

The visibility graph approach and complex network theory provide a new insight into time series analysis. The inheritance of the visibility graph from the original time series was further explored in the paper. We found that degree distributions of visibility graphs extracted from Pseudo...

In this paper, we consider the problem of allocating an indivisible good between two agents under incomplete information. We provide a characterization of mechanisms that maximize the sum of the expected utilities of the agents among all deterministic feasible strategy-proof mechanisms: Any...

This paper analyzes the problem of matching two heterogeneous populations, e.g., men and women. If the payoff from a match exhibits complementarities, it is well known that absent any friction positive assortative matching is optimal (PAM). Coarse matching refers to a situation in which the...

In this paper, we consider the problem that a benevolent designer wants to provide a non-excludable public good with a fixed cost to agents with privately known valuations. Adopting utilitarian's point of view, the designer maximizes the ex-ante total utility of all agents. The impossibility...
