Nitrous oxide (N 2 O) production and consumption occur concomitantly in the soil and their accurate quantification as the gas diffuses in situ under high background concentration of atmospheric dinitrogen remains largely elusive. This study designed an analytical and reliable approach for...

We present a simple discrete-time version of the continuous-time agency model under mean-volatility joint ambiguity uncertainties, which conveniently captures a number of important properties of optimal contracts without having to rely on complex continuous-time mathematical issues. The...

This paper provides a model that uses preference heterogeneity to rationalize the cross-sectional and intertemporal variation in a firm's product proliferation strategies. Product-line dynamics arise from shocks to preference heterogeneity. For example, in the potato chip category I study,...

Many online-first retailers have adopted omnichannel strategies to expand their territories from online to offline. In this paper, we seek to understand the function of offline showroom for multi-category online retailing platforms, which is relatively understudied. Using detailed...
