Interest risk and default risk: A conditional volatility study

The aim of this work is to measure the risk-price sensitivity to interest rate changes in the Spanish market and to see if sensitivity is lower with public debt. To contrast this hypothesis, this study presents a model that analyzes the sensitivity of the risky prices before variations in interest rates through duration and convexity, with the purpose of explaining the price of risky bonds. The main advantages of the analysis are the possibility to determine the sensibility of the risky prices before variations of risk-free interest rates in the Spanish market and the construction of a conditional volatility model that overcomes the linearity models of constant variance.     

Debt Concentration and Bargaining Power: Large Banks,Small Banks,and Secondary Market Prices

Commerical bank debts of developing countries are held by large international banks and smaller domestic banks. This paper investigates how debt concentration—the proportion of a country's debt held by large banks relative to small banks—affects the secondary market price for these loans. We find that countries with higher concentrations have higher secondary-market prices. We explain this empirical finding in a bargaining model that endogenizes the maximum penalty that banks can credibly impose on a recalcitrant debtor. We show that the banks' bargaining power increases with the degree of debt concentration, thus increasing repayment and secondary-market prices.     

金融冲击与房地产市场波动*——一个宏观分析框架及中国的经验证据

本文从总量宏观分析的视角,提出了金融变量与房地产市场的“总体冲击—传导机制”假说,据此用中国的数据构建金融状况指数（包含房价的FCI1和不包含房价的FCI2）,再对金融状况指数（FCI1和FCI2）与房地产指数做实证分析。研究发现,在资产价格中房价比股价更能反映一国的金融状况;在引入金融状况指数的金融变量中,利率与房价的相关性最强;房价和利率对总产出的影响周期更长。国房景气指数、房地产投资指数和房价指数对FCI冲击的响应显著,并存在不同的表现。由于房价对居民财富、金融状况和宏观经济的影响显著,货币政策理应干预房价,必须精准把握干预的时机和干预的力度以及注重多种货币政策工具的有效搭配使用。     

Consumption opportunities and the real value of the external debt

Developing countries have, in the period since the oil shock of 1973–1974, built up large external indebtedness. At the same time world inflation has in good part eroded the real value of existing debts. But the measurement of the inflation effects on real debt depend critically on which among a number of deflators is selected. The deflators proposed in this context have traditionally been export prices, import prices or prices in world trade. This paper argues that the correct deflator is the domestic consumer price index. Using the consumer price index as a debt deflator it is readily shown that conventional results in trade theory are recovered in the presence of external indebtedness: The income effect of an export price increase is proportional to the level of exports, the income effect of an import price increase is proportional to the level of imports. Real income, using a comprehensive income measure, is equal to the value of domestic output less the real value of real interest payments on external debt.     

Testing for rational bubbles in the US housing market

The presence of a bubble in the US housing market prior to the 2007 subprime mortgage financial crisis is investigated. This is done by looking into the relationship between house prices and rental prices, known as the price–rent ratio, which is an important measure of a potential deviation between house prices and its fundamental value. Additionally, the interest rate is taken into account since it is an important factor in determining demand for housing mortgages and thereby influencing house prices, and explosive behavior of house prices is considered. These relationships are investigated through a theoretical and econometrical framework. The empirical evidence suggests that there was a bubble in the housing market prior to the financial crisis, even when controlling for the decreasing interest rate and the fundamental information given by the rental price in the period. Explosiveness was the main source of the price increase, such that a bubble was present in the housing market after correcting for other fundamental factors. The econometric procedures used in the analysis may therefore be relevant for monitoring the housing market.     

Feedback effects between credit ratings and financial markets

Credit rating agencies often make sharp adjustments in their pronouncements during times of stress in financial markets. These adjustments typically happen with a delay relative to shocks in market prices. Since prices convey information about what market participants are doing and thinking, it is likely that rating agencies take into account market prices when issuing their pronouncements.In order to understand the relationship between credit ratings and financial prices, we develop a model of debt roll-over in which rating agencies incorporate information publicly available in financial markets. We find that (1) rating agencies respond to market prices, i.e. nonfundamental price volatility can shift financing conditions from a low risk spread and high credit rating equilibrium to an equilibrium with high spread and low rating, and (2) rating agencies can anchor expectations about the equilibrium in financial markets, thus serving as an antidote to nonfundamental price volatility.     

Analyzing time–frequency relationship between interest rate,stock price and exchange rate through continuous wavelet

In this study we investigate and identify the patterns of co-movement of interest rate, stock price and exchange rate in India in the period between July 1997 and December 2010 using the cross-wavelet power, the cross-wavelet coherency, and the phase difference methodologies. Our empirical findings suggest that stock prices, exchange rates and interest rates are linked. The cross wavelet results show that stock price movements are lagging both to the exchange rate and interest rate fluctuations. The interest rate lead over the stock price movements is even clearer, especially after 2006, and it suggests that the stock market follows the interest rate signals. Comparing results of WTC and XWT, we find very clear results of phase difference of lead–lag relationship between stock prices, exchange rates and interest rates.     

A time series analysis of causality between aggregate merger and stock prices: the case of Canada

It is widely agreed that a positive relationship exists between measures of aggregate merger activity and measures of stock market performance, at least for the USA. Evidence from other countries is relatively sparse. in this paper we pursue the causality question using Canadian data. Most of the previous studies used only a bivariate system (merger and stock prices). We have extended the analysis to trivariate system (merger, stock prices and interest rate) to better reflect the capital market conditions argument for changes in merger activity. The results suggest a bidirectional causality between mergers and stock prices.

A Novel Housing Price Misalignment Indicator for Germany

From 2014 until present, housing prices in Germany have been rising faster than consumer prices in all quarters except one, raising concerns about an excessive overheating of the housing market. To assess the vulnerability of the German housing market to a future realignment of prices or even a housing bust, this paper develops a housing price misalignment indicator that is composed of seven indicators, which are commonly associated with the fundamental value of residential property. An empirical application to the most recent data suggests that the German housing market exhibits an overvaluation of approximately 11%, where interest rate risk and a relatively advanced stage of the housing cycle are identified as the main factors fueling these imbalances, while a rather solid debt‐servicing capacity mitigates these imbalances since end‐2009.     

分析师利益冲突、乐观偏差与股价崩盘风险

"股价崩盘风险"是当前金融危机背景下财务学的一个研究热点。本文使用2003-2010年中国A股上市公司的数据,研究分析师乐观偏差是否影响上市公司股价崩盘风险,并考察分析师面临的"利益冲突"是否会加剧乐观偏差对股价崩盘风险的影响。研究发现:(1)分析师乐观偏差与上市公司未来股价崩盘风险之间显著正相关,且此关系在"牛市"更为显著;(2)机构投资者持股比例越高,机构投资者数量越多,公司存在再融资行为,以及来自前五大佣金收入券商的分析师比例越高,分析师乐观偏差与崩盘风险之间的正向关系就更为显著,说明"利益冲突"会加剧两者的关系。本文的研究对于全面认识分析师在资本市场中的作用,以及如何降低我国股价崩盘风险、促进股市平稳发展具有重要的理论和现实意义。

Influence of economic factors on the valuation effects of debt offerings

The obejective of this paper is to determine whether the share price responses to debt offerings are influenced cross-sectially by economic factors. We develop hypotheses that share price responses are inversely related to nominal interest rates, and to the issuing firm's stock price level relative to the market, and positively related to economic growth. After controlling for firm-specific characteristics used in previous studies, we find that the share price responses to straight debt offerings are not significantly related to the nominal interest rates or to the issuing firm's relative stock price level, but are positively related to the economic growth. We also find that share price responses to convertible debt offerings are significantly related to the nominal interest rates, the issuing firm's relative stock price level, and economic growth in the manner hypothesized. These results imply that the signal emitted by a firm's debt offering can be influecnced not only by firm-specific characteristics, but also by prevailing economic conditions.     

Bidding and Information: Evidence from Gilt-edged Auctions

Many studies have shown that government debt auctions underprice debt compared with the secondary market. This paper corroborates this for certain forms of gilt auction by comparing the price received at auction with an almost identical parent stock in the secondary market. Although the sample is small, the parent/auction stock price comparison gives a cleaner measure than used in other studies. The paper also compares non-fungible auctions (where the auction stock differs slightly from the parent at auction and merges subsequently) with fully-fungible ones (where they are identical throughout). Significant underpricing only occurs in non-fungible auctions.     

External shocks and persistence of external debt in open vulnerable economies: The case of Africa

We examine the extent to which two external shocks, the world interest rate shock and the commodity price shock, lead to external debt accumulation in Africa. We begin by estimating a dynamic stochastic general equilibrium model of external debt burden, and solve the linear equations using the quadratic method of undetermined coefficients. Consequently, we run simulations of 50 time periods. Our results show that both world commodity price and world interest rate shocks impact external debt accumulation in the majority of our sample African countries. Interestingly, world commodity price shocks lead to an increase in external debt while world interest rate shocks appear to discourage accumulation of external debt.     

The empirical study on price discovery of cornstarch futures market in China

This article aims at exploring the performance of the price discovery function of cornstarch futures market in China. In order to test the stationarity of the cash and futures prices of cornstarch, the augmented Dickey–Fuller test is applied. Both prices are integrated of order one. Then, the Johansen cointegration test is conducted to test the cointegrating relationship between those two prices. Finally, the Granger causality test is performed to observe the direction of causality. The evidence shows that there is a long-run relationship between cash and futures prices and the futures price Granger causes cash price. As a whole, price discovery of cornstarch market in China is present although it is a newly emerged market.     

The drivers of household indebtedness reconsidered: An empirical evaluation of competing arguments on the macroeconomic determinants of household indebtedness in OECD countries

Abstract

Household debt is at a record high in most Organisation for Economic Co-operation and Development (OECD) countries and it played a crucial role in the recent financial crisis. Several arguments on the macroeconomic drivers of household debt have been put forward, and most have been empirically tested, albeit in isolation of each other. This article empirically tests 7 competing hypotheses on the macroeconomic determinants of household indebtedness together in one econometric study. Existing arguments suggest that residential house prices, upward movements in the prices of assets demanded by households, the income share of the top 1%, falling wages, the rolling back of the welfare state, the age structure of the population, and the short-term interest rate drive household indebtedness. We formulate these arguments as hypotheses and test them for a panel of 13 OECD countries over the period 1993–2011 using error correction models. We also investigate whether effects differ in boom and bust phases of the debt and house price cycles. The results show that the most robust macroeconomic determinant of household debt is real residential house prices, and that the phase of the debt and house price cycles plays a role in household debt accumulation.     

上市公司、资本虹吸与房价的地区差异

鉴于上市公司与房价地区差异的研究鲜见,文章首次从地区层面寻找上市公司影响房价的微观传导路径.研究发现,上市公司从一级市场上融资、内部人在二级市场上减持均会"虹吸"全国资金,增加当地货币资本,进而正向影响房价,即高融资或高减持地区成为"虹吸方";融资虹吸与减持虹吸对房价的影响存在差异,减持虹吸引起财富集聚,对房价的影响更多地由富裕阶层的购房需求所推动,而融资虹吸带来的财富影响比较分散.地区股票市值与房价呈现螺旋增长关系,在股市上涨期间替代效应占主导地位,两者的增长率负相关;而在下跌期间财富效应占主导地位,两者的增长率正相关.文章从企业层面阐释了房价地区差异的金融成因及路径,并试图厘清股票市场与房价的增长结构,为地区经济的协调发展提供了参考.     

A frequency domain causality investigation between futures and spot prices of Indian commodity markets

This paper examines the direction, strength and extent of causal relationship between futures and spot prices of Indian commodity markets using frequency domain approach of Breitung and Candelon (2006). Frequency domain analysis offers an effective alternative tool by examining the causality in frequency domain, whereas in traditional econometric causality analysis tools focus only on the time domain. Daily futures and spot price series on eight commodities from the Indian commodity exchanges (MCX and NCDEX) were examined for the period 3rd January, 2008 to 31st December, 2012. The results of frequency domain analysis suggest that there is a strong uni-directional relationship from futures to spot in almost all the selected commodities. This indicates that futures market has a powerful price discovery function in all the selected commodities; which in turn indicates the efficiency of Indian commodity futures market.     

Structural breaks,cointegration and the farm-retail price spread for lamb

This paper examines the farm—retail price spread for lamb from monthly UK data for 1979–1993. Using cointegration, it examines seasonal patterns in producer and retail prices and seeks to identify a long-run relationship between them. Results show that a long-run relationship exists, and that the direction of Granger-causality is from retail to producer prices. Lamb prices are therefore set in the retail market. Results also show that there is a structural break in the relationship in January 1990 when the price increases; this coincides exactly with a change in policy.
