In theory, the choice of ReLU(0) in [0, 1] for a neural network has a negligible influence both on backpropagation and training. Yet, in the real world, 32 bits default precision combined with the size of deep learning problems makes it a hyperparameter of training methods. We investigate the...

As a result of COVID-19, the export of medical goods has been subject to various global restrictions. Consequently, several countries have increased the supply of medical goods to alleviate the effects of this health crisis. This study entails a theoretical and empirical analysis of the effects of...

An incumbent seller contracts with a buyer under the threat of entry. The contract stipulates a price and a penalty for breach if the buyer later switches to the entrant. Sellers are heterogenous in terms of the gross surplus they provide to the buyer. The buyer is privately informed on her...

This article investigates the impact of flood risk on vulnerability and welfare at the household level in Vietnam. The analytical sample is taken from a household survey conducted in a north central Vietnam community through a three-stage stratified random sampling method. The propensity score...

In view of training increasingly complex learning architectures, we establish a nonsmooth implicit function theorem with an operational calculus. Our result applies to most practical problems (i.e., definable problems) provided that a nonsmooth form of the classical invertibility condition is...

Econometric land use models study determinants of land use shares of different classes: “agriculture”, “forest”, “urban” and “other” for example. Land use shares have a compositional nature as well as an important spatial dimension. We compare two compositional regression models with a spatial...

Individuals and society value safety, but safety does not have an easily available market price. This is a problem for cost-benefit analysis (CBA), which is a powerful tool to evaluate government policies, as it requires that all benefits and costs are measured in a common metric, which usually is...

It is shown that every spectrum of a finite irreducible Markov generator whose eigen-values are real and of geometric multiplicity 1 can be obtained as the spectrum of an irreducible pure-birth Markov process with jumps from the right-most boundary to all the other points. A whole isospectral...

Artificial Intelligence (‘AI’) and machine learning (‘ML’) — adaptive computer programs that attempt to perform functions typically associated with the human mind — offer new opportunities for improving the decision-making capacity and productivity of the Indian judiciary. First, the algorithmic...

COVID-19 has had worse health, education, and labor market effects on groups with low socioeconomic status (SES) than on those with high SES. Little is known, however, about whether COVID-19 has also had differential effects on noncognitive skills that are important for life outcomes. Using panel...
