Within the framework of the POLARCAT-France campaign, aerosol physical, chemical and optical properties over Greenland were measured onboard the French ATR-42 research aircraft. The origins of CO excess peaks detected in the aircraft measurements then have ...
In this work we report an experimental study on accumulation-mode (AM) gate-all-around (GAA) nMOSFETs based on silicon nanowires with uniaxial tensile strain. Their electrical characteristics are studied from room temperature up to ~400 K and carrier mobil ...
One of the major advantages of stencil lithography is the possibility to use stencils many times. However, when stencils contain nanoapertures, the clogging of the membranes limits the useful life time of the stencils. The clogging is due to the accumulati ...
This paper proposes a capital accumulation model with a random stopping time corresponding to the occurrence of an environmental catastrophe. Depending on the preventive capital stock accumulated at the time of the catastrophe, the damage cost associated w ...
The IMP group's ARA model, with its emphasis on interaction, captures social and economic dimensions of exchanges. We draw on it to compare three cases and assess how actors act in skilful and nuanced ways in mobilizing resources, given the very different ...
This paper examines the effects of capital gains taxation on firms’ investment and financing decisions. We develop a real options model in which the timing of investment, the decision to default, and the firm’s capital structure are endogenously and jointl ...
Eleven percent of the largest public U.S. firms are headed by the CEO who founded the firm. Founder-CEO firms differ systematically from successor-CEO firms with respect to firm valuation, investment behavior, and stock market performance. Founder-CEO firm ...
This paper develops a framework for analyzing the impact of macroeconomic conditions on credit risk and dynamic capital structure choice. We begin by observing that when cash flows depend on current economic conditions, there will be a benefit for firms to ...
We relate the value of growth options in the firm's investment opportunity set to the level of debt in the firm's capital structure. Underinestment costs of debt increase and free cash flow benefits fall with additional growth options. Thus, if debt capaci ...
Structural models of default calibrated to historical default rates, recovery rates, and Sharpe ratios typically generate Baa-Aaa credit spreads that are significantly below historical values. However, this "credit spread puzzle" can be resolved if one acc ...
