Limits to creative destruction and technologies in practice: the case of ham radio

Drawing on the structurationist notion of ‘technologies-in-practice’, this article analyses the different types of technological actions that users perform, after technological change, in order to keep a declining technology alive over time. The research question of the article is: How do technologies-in-practice based on the application of new technology hamper the creative destruction of old technology? The case study of ham radio technology and amateur radio operators is explored. The results of the investigation support the development of a technology-in-practice ‘experimentation’ and four inductive research propositions.     

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.

Does trade integration alter monetary policy transmission?

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies.

基于小波的窄带通信干扰抑制研究的探讨

窄带干扰(NBI)对直接序列扩频通信系统(DSSS)的破坏性很强,当有强窄带干扰存在时仅靠系统自身的抗干扰能力很难保证系统高质量的通信,甚至可能造成系统通信中断。因此,研究有效的窄带干扰抑制技术具有重大的实际意义。
