工业产品质量指数编制的理论探讨

现行工业产品质量指数因直接相加产品抽查批次、没有考虑产品市场占有率、且不具抽样随机性原则而有失科学性。以统计指数基本理论为依据 ,用“质量指数”替代“产品质量稳定提高率” ,理论和实践上均具可行性。     

Choosing sides in the trilemma: international financial cycles and structural change in developing economies

ABSTRACT

This paper analyzes the impact of international financial cycles on structural change in developing economies. It is argued that the impact of these cycles depends on the specific combination of macroeconomic and industrial policies adopted by the developing economy. The cases of Brazil and Argentina are contrasted with those of Korea and China. In the Asian economies, macroeconomic policy has been a complementary tool along with industrial policy to foster the diversification of production and capabilities. Inversely, in the case of the Latin American countries, long periods of real exchange rate (RER) appreciation, combined with the weaknesses (or absence) of industrial policies, contributed to the loss of capabilities and lagging behind.     

Exchange rates and bertrand oligopoly

The impact of exchange-rate changes on industrial prices seems ambiguous. Incomplete and even perverse pass-through has been observed: the import prices in the depreciating country decrease while those in the appreciating country increase. To explain these counterintuitive price reactions we consider a situation of international Bertrand competition: two firms, based in different countries, are selling in both countries simultaneously. The profit-maximizing duopolists set the prices for their products in each of the two markets which are segmented on the demand side. We then study the qualitative effect of an exogenous exchange-rate change on the Bertrand-Nash equilibrium. Under the strong assumption of linear demand and cost functions we have normal exchange-rate pass-through. However, allowing for more general cost structures in this simple static model enables us to show that the import prices in both countries might move in counterintuitive directions.

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.     

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.     

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.
