Traffic flow directionality and network weight asymmetry are widespread notions in traffic networks. This paper investigates the influence of direction-dependant heterogeneity on traffic congestion. To capture the effect of the link directionality and link weight asymmetry, the heterogeneity...

Avalanche or cascade failure is ubiquitous. We first classify the cascading phenomena into two categories: the cascading disasters which result in large-scale functional failures and the cascading events that do not lead to disasters. We elucidate that two important factors, the increasing...

The collective dynamics of large-scale computer networks remains elusive due to not only the internal adaptive behaviors of network-wide flows, but also the spatial–temporal changes in the external environment. In this paper, we investigate the time-dependent collective behavior by using a...

We document in the US data: (1) The dominant predictable component of investment-sector TFP is its long-run movements, and a favorable shock to predictable changes in investmentsector TFP induces a broad economic boom that leads actual increases in investment-sector TFP by almost two years, and...

Five-category loan classification (FCLC) is an international financial regulation approach. Recently, the application and implementation of FCLC in the Chinese microfinance bank has mostly relied on subjective judgment, and it is difficult to control and lower loan risk. In view of this, this...

We present sharp asymptotic limit properties of the maximum of the occupation measure around intervals for a transient Brownian sheet. The corresponding multifractal analysis via packing dimension for occupation measures is also established.

The U.S. current account deficit has deepened significantly since the late 1990s. This shortfall—the value of net exports of goods and services, international financial investment net income and transfer payments—was $803 billion at its peak in 2006, or 6 percent of U.S. gross domestic...

This article imports a behavioural perspective into a team context to study the effort-coordination problem among agents. Specifically, we investigate how the presence of optimism bias impacts the severity of the free-rider problem, the organizational structure of the team and the compensation...
