A Brief Survey of Modern Optimization for Statisticians

Modern computational statistics is turning more and more to high‐dimensional optimization to handle the deluge of big data. Once a model is formulated, its parameters can be estimated by optimization. Because model parsimony is important, models routinely include non‐differentiable penalty terms such as the lasso. This sober reality complicates minimization and maximization. Our broad survey stresses a few important principles in algorithm design. Rather than view these principles in isolation, it is more productive to mix and match them. A few well‐chosen examples illustrate this point. Algorithm derivation is also emphasized, and theory is downplayed, particularly the abstractions of the convex calculus. Thus, our survey should be useful and accessible to a broad audience.

The Impact of Foreign Banks on Monetary Policy Transmission During the Global Financial Crisis of 2008–2009: Evidence from Korea

This article examines the impact of foreign banks on the monetary policy transmission mechanism in the Korean economy during the period from 2000 to 2012, with a specific focus on the lending behavior of banks with different types of ownership. Using bank-level panel data of the banking system in Korea, we present consistent evidence on the buffering impact that the foreign banks, especially foreign bank branches including US bank branches, on the effectiveness of the monetary policy transmission mechanism in Korea from the bank-lending channel perspective during the global financial crisis of 2008–2009.     

慕课视野下高职院校的教学模式改革研究

在互联网高度普及的情况下,慕课作为一种新的知识传播手段,必然会带来教学模式的变化,对于高职教育也不例外。本文分析了纯慕课教学模式与传统教学模式的优劣,然后针对高职教育及高职学生的自身特点来构建高职混合慕课教学模式,以及应用该教学模式来有效提高高职学生的学习兴趣与学习效率、提高高职教师的教学水平和教学效率。     

The impact of the global financial crisis on the cross-currency linkage of LIBOR–OIS spreads

This article examines the impact of global financial crisis on cross-currency linkage of the LIBOR–OIS spread, a financial stress measure in interbank markets. The impulse response analysis is conducted in a multivariate setting, adopting the bias-corrected bootstrap as a means of statistical inference. The overall evidence suggests that the crisis has substantially changed the nature of the cross-currency interactions in liquidity stress. Also global money markets have failed to contain stress in US dollar funding and the role of the Japanese yen as a liquidity source appears to be significant, while these two currencies drive the cross-currency system of liquidity stress.
