Geopolitical Risks and Movements in Islamic Bond and Equity Markets: A Note

Abstract This study applies a non-parametric causality-in-quantiles test to examine the causal effect of geopolitical risks on return and volatility dynamics of Islamic equity and bond markets. Geopolitical risks are generally found to impact Islamic equity market volatility measures, rather than returns. However, geopolitical risks tend to predict both returns and volatility measures of Islamic bonds. Interestingly, causality, when it exists for returns and/or volatility of Islamic equities and bonds, is found to hold over entire conditional distributions of returns and volatilities, barring the extreme ends of the same.

The Dynamic Relationship between Housing Prices and the Macroeconomy: Evidence from OECD Countries

This paper studies the dynamic relationship among house prices, income and interest rates in 15 OECD countries. We find that any disequilibrium in the long-run cointegrating relationship among these variables is corrected by the subsequent movement in house prices in most of these countries. This error-correction property of house prices implies that most of the variations in house prices are transitory, as compared to the movements in income and interest rates that are permanent, suggesting that the short-run movements in house prices are independent of the movements in income and interest rates. The results suggest that only the permanent movement in house prices, income and interest rates are associated with each other. We also find that the correlation in house price cycles across different OECD countries has changed over time with the highest correlation during the boom period of 1998–2005.

The international REIT’s time-varying response to the U.S. monetary policy and macroeconomic surprises

Abstract International real estate markets and the ever increasing role of the U.S. economic and policy developments have played a central role both in international portfolio management as well as broader economic policy making. In this paper, we measure the extent of time-varying impact of the U.S. monetary policy and macroeconomic news on the international Real Estate Investment Trusts (REITs) stock returns. Results suggest that there has been significant variation both across time and across countries in the impact of U.S. news on the global REIT stocks. Further, the country’s stock market capitalization to GDP ratio has strong connections with the time-varying nature of the impact of the U.S. news on the global REIT stock returns.

Estimating excess sensitivity and habit persistence in consumption using Greenbook forecast as an instrument

In this paper, we revisit the issue of excess sensitivity of consumption to income and address the weak instrument problem that is well documented in this literature. Using quarterly data for the U.S. economy, we first highlight the weak instrument problem by showing that the use of conventional instruments tends to overestimate the share of rule-of-thumb consumers. To address this weak instrument problem, we propose a new instrument for endogenous disposable income growth in the consumption function, namely, the Greenbook forecast of real disposable income growth. We show that this instrument encompasses the information contained in the conventional set of instruments, and is a superior predictor of income growth. We find that using our proposed instrument ameliorates the weak instrument problem and provides a much smaller estimate for the rule-of-thumb consumers. We also extend our empirical framework to allow for habit persistence and provide an estimate for this important parameter of the consumption function. Finally, we use a time-varying specification of consumption function that allows for endogenous regressors, and document a decline in the share of rule-of-thumb consumers and a rise in the habit- persistence parameter in the U.S. over our sample period. We find that an increase in credit growth and supplementary income benefits are negatively correlated with share of rule-of-thumb consumers, whereas they are positively correlated with habit persistence parameter.

Exploring the Dynamic Relationship in the Shadow Banking System

In this paper, we study the dynamic relationship in the shadow banking system by examining the short-run and the long-run relationship among the financial assets of the money market fund, the commercial paper, and the repurchase agreement market. The evidence suggests that there exists a common long-term cointegrating trend among these three components of the shadow banking system for 1985-2013 sample period. Any disequilibrium in this long-run relationship among these variables is corrected by movement in the financial assets of the money market funds. The trend-cycle decomposition from the estimated cointegrating relationship shows that the cyclical component in the money market funds is large and captures the huge swings in these markets during the financial crisis. Our results are also robust to the exclusion of the financial crisis, and it reveals the changing role of the commercial paper and the repurchase agreement market in the shadow banking system.
