We estimate annual discontinuities in remotely-sensed crop yields at all international land borders and link them to changes in the economic freedom index by the Fraser Institute, a country-level measure of institutional quality. Each point of the ten-point index increases the discontinuity by...

A causal vector autoregressive (CVAR) model is introduced for weakly stationary multivariate processes, combining a recursive directed graphical model for the contemporaneous components and a vector autoregressive model longitudinally. Block Cholesky decomposition with varying block sizes is...

Epidemics represent a threat to human life and economy. Meanwhile, medical and non-medical approaches to fight against them may result in additional economic shocks. In this paper, we examine the economic impact of the 2003 SARS outbreak in China and associated government policies. Although the...

As the increasing IT energy consumption emerged as a prominent issue, computer system energy consumption monitoring and optimization has gradually become a significant research forefront. However, most existing energy monitoring methods are limited to hardware-based measurement or coarse-grained...

For nearly half a century, existing studies on institutions and institutional change have produced a large number of results from different perspectives and concepts, however, existing studies still lack a unified dynamic framework. In this paper, based on the existing research, a generalized...

We extract cyclic information in turnover and find it can explain the momentum “echo”. The reversal in recent month momentum is the key factor that cancels out the recent month momentum and excluding it makes the “echo” regress to a damped shape. Both rational and behavioral theories can...
