货币政策的产业效应分析——基于中国货币政策的实证研究

本文从基于要素密集度不同的两部门例子出发，说明了由于行业自身的异质性，每个行业对同一货币政策冲击的反应各异。接着利用E—G两步法、ADL模型和基于VAR模型的脉冲响应函数分析1995年后中国六个行业对货币政策冲击的反应。结果显示第一、二产业、房地产业对利率政策冲击反应明显，第三产业、餐饮业和批发贸易零售业反应较小。在此基础上简单分析了造成行业反应不同的原因并给出相关的政策建议。     

基于目标替代率的税延型商业养老保险扣除限额优化研究

我国养老保障体系三支柱发展严重失衡,为了缓解基本养老保险的压力,提升养老保险替代率,商业养老保险的发展迫在眉睫,税收递延型商业养老保险也开始试点。在2018年个税改革后,目前税收递延型商业养老保险推行办法下,中低收入群体无法享受实际税收优惠,高收入群体可享受的税收优惠有限且过低。本文以替代率为基准,根据精算平衡原理构建模型,对扣除限额进行优化研究,试图测算出与新个税办法匹配且有利于多层次收入水平的消费个体享受实际税优的扣除限额。同时,本文还对不同扣除限额下开始购买保险年龄、个税起征点、个人收益率及初始收入水平这四个参数变化对实际税优额的影响做了分析,得出所测算出的扣除限额的确较现行扣除限额更为合理,并提出了相关对策建议。     

Real Exchange Rate and External Balance: How Important Are Price Deflators?

This paper contrasts real effective exchange rate (REER) measures based on different deflators (consumer price index, GDP deflator, and unit labor cost) and discusses potential implications for the link—or lack thereof—between the REER and the external balance. We begin by comparing the evolution of different measures of REER to confirm that the choice of deflator plays a significant role in REER movements. A subsequent empirical investigation based on 35 developed and emerging market economies over 1995–2017 yields comprehensive and robust evidence that only the REER deflated by unit labor cost exhibits contemporaneous patterns consistent with the expenditure-switching mechanism. Finally, we show that a standard open-economy model with nominal rigidities and trade in intermediate goods is able to generate these aforementioned patterns.     

Foreign-currency transactions and the recovery of German industry in the aftermath of the First World War: the case of Schering AG

While historians have for a long time recognized the importance of the First World War to the general flow of history, business economists do not fully appreciate the impact of the war on commercial relationships. The First World War transformed the political, economic, and social context, in which business was done, forcing companies to develop new strategies and activities, some of which were almost unimaginable before August 1914. This article focuses on one aspect of doing business: foreign exchange management. It argues that Schering AG and its parent, like many German companies after the First World War, were obliged to refocus their activities around their foreign exchange exposures and that the management of foreign exchange issues contributed to a much tighter relationship between businesses, government, and business associations than had existed before the war and for which some aspects of Germany's system of corporate control were not well adapted to handle.     

Implied Volatility of Interest Rate Options: An Empirical Investigation of the Market Model

We analyze the empirical properties of the volatilityimplied in options on the 13-week US Treasury bill rate. These options havenot been studied previously. It is shown that a European style put optionon the interest rate is equivalent to a call option on a zero-coupon bond.We apply the LIBOR market model and conduct a battery of validity tests tocompare three different volatility specifications: contact, affine, and exponentialvolatility. It appears that the additional parameter in the affine and theexponential volatility function is not justified. Overall, the LIBOR marketmodel fares well in describing these options.     

Regional and State Variation in Homeownership Rates; or If California's Home Prices Were as Low as Pennsylvania's Would its Ownership Rate be as High?

There are significant disparities in homeownership rates across the regions and states of the United States. The causes of these disparities are determined within a standard probit model of the individual homeownership decision where the micro-level observations are aggregated to the regional level. Factors which play a significant role at the individual level are evaluated for their ability to explain regional differentiation. The relative price of owning and renting plays a major role as do other market level determinants. Individual demographic characteristics are not as important with the exception of those related to the immigration and citizenship status of the household head.

Money and exchange rates in the Grossman-Weiss-Rotemberg model

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.     

Cross-hedging foreign currency risk: Empirical evidence from an error correction model

In this article, the traditional price change hedge ratio estimation method is extended by applying the theory of cointegration in the case of cross-hedging of spot exchange risk of the Belgian franc (BF), the Italian lira (IL), and the Dutch guilder (NG) with U.S. Dollar Index futures contracts. Previous studies ignore the last period's equilibrium error and short-run deviations. The findings of this study indicate that the hedge ratio estimated by the error correction method is superior to that obtained from the traditional method, as evidenced by the likelihood ratio test and out-of-sample forecasts. Hedgers will be able to control the risk of their portfolios more effectively at a lower cost.
