As long as workers do not value their leisure much, the Mortensen-Pissarides search and matching model implies that unemployment and job vacancies would be much less responsive to changes in labor productivity than what we observe in the business cycles of the Canadian labor market. These...

Two-color triangular urn models have been investigated recently. Moments of ball counts of a particular color have been obtained exactly and asymptotically in a number of sources (Janson, 2006, Kuba and Panholzer, 2014, and Flajolet et al., 2006). Exact factorial moments are in Kuba and...

Modeling portfolio credit risk involves the default dependencies between the individual securities in a portfolio. The copula is a common approach to construct it. It parameterizes the joint distribution of individual defaults independently of their marginal distributions. The current market...

China’s urban agricultural development takes on stage evolution, and functional structure, customer structure, industrial organization, innovation activity, spatial form and industrial value of each stage has significant difference. Using the system variable analysis method, this paper...

This paper uses a set of unique data from Chinese listed companies to examine the influence of analyst coverage on corporate philanthropy. Results show that companies followed by more analysts engage in more philanthropy, which provides support for the reputational capital view of corporate...

The algorithm, generalized orthogonal components regression (GOCRE), is proposed to explore the relationship between a categorical outcome and a set of massive variables. A set of orthogonal components are sequentially constructed to account for the variation of the categorical outcome, and...

The mathematical model is often used for fitting the trend of changes in cultivated land resources in the land use planning, but the fitting effect is different in different study areas. In this paper, we take two geographically adjacent cities with great differences in the economic development...

Since high temperature superconducting magnetic energy storage system (HT SMES) has attracted significant attention for their fast response in milliseconds, high efficiency (cyclic efficiency over 95%) and unlimited times of charging and discharging cycles, it can be used for system stabilizing...

The demand for petroleum has risen rapidly due to increasing industrialization and modernization of the world. The limited reserve of the fossil fuels is also dwindling alongside escalation in the prices. The threats from these and food insecurity are, however, drawing the attention of...
