Does the launch of an Analytics and Data Science (ADS) graduate program increase the ADS job opportunities in its local area? Using job postings data and a difference-in-difference event-study design, we find that an ADS program increases the number of job postings by 11.2 and the number of ADS...

We examine how the presence of a firm’s political connections in a candidate location affects the firm’s likelihood of choosing that location over unconnected but otherwise comparable ones to establish a new subsidiary. First, because of various benefits that political connections can...

The J-TEXT Tokamak device has the operation ability of the high field side horizontal divertor configuration. Under this divertor configuration, plasma equilibrium is unstable in the horizontal direction. This work studies the performance of the horizontal displacement control system to the...

Soil extracellular enzymatic stoichiometry, the ratio of soil enzyme activities related to the acquisition of nutrients such as carbon (C), nitrogen (N), and phosphorus (P), which can reflect the demand for resources by microorganisms. However, how cover crop and chemical fertilizer shift...

A serial of of pyridine-based chelates M-PYPA were synthesized via a facile and green strategy. The chelates served as highly efficient catalysts toward CO 2 cycloaddition. For Fe-PYPA, a conversion rate of 95.8% and a product selectivity of 98.6% to PO were achieved at 100 °C with 1.5 MPa CO 2...

Firms that are more central invest more in equilibrium. Central firms are exposed to larger idiosyncratic shocks that propagate in the production network. Their incentive to engage in precautionary saving is larger, leading to larger investment. In the data, I find support for this prediction,...
