The effects of Federal funds rate surprises on S&P 500 volatility and volatility risk premium

In this paper, we examine the effects of expected and surprise components in Federal funds target rate changes on realized and implied volatility. We find that surprise changes in the target rate significantly increase volatility. Consistent with the efficient market hypothesis, our analysis suggests that the expected component of a target rate change as well as the target rate change itself, do not significantly affect volatility. We also show that larger than expected decreases in the Federal funds target rate tend to lower the volatility risk premium.     

Aid,Aid Volatility and Sectoral Growth in Sub-Saharan Africa: Does Finance Matter?

This article examines the impact of aid and its volatility on sectoral growth by relying on panel dataset of 37 sub-Saharan African (SSA) countries for the period 1983–2014. Findings from the system-generalized methods of moments show that, while foreign aid significantly drives sectoral growth, aid volatility deteriorates sectoral value additions impacting heavily on non-tradable sectors with no apparent effect on the agricultural sector. The deleterious effect of aid volatility on sectoral value additions in SSA is weakened by a well-developed financial system with significant impact on the tradable sector. Evidently, development of domestic financial markets enhances aid effectiveness.     

Gender diversity in the hospitality industry: An empirical study in Turkey

This paper, an investigation of gender diversity in the Turkish hospitality industry, focuses on two primary objectives: (a) exploring the potential relationships between gender and several demographic factors, and (b) examining the possible existence of a gender effect regarding employees’ perceptions of recruitment and earning potential decisions. Results, based on 682 surveys, show that, in the male-dominated Turkish hospitality industry, there is a significant gender effect for two of four demographic variables and with respect to recruiting efforts and earning potential. These findings could have some important managerial implications for addressing gender diversity in the (Turkish) hospitality industry.     

Does training benefits lead to acquisition of livelihood assets and change in social status? Evidence from training of rice farmers

Livelihood assets which are considered and recognised for their life-supporting role contribute significantly and basically to the standard of living of people. These contributions as deemed more meaningful are considered necessary to farmers whenever an opportunity exists to diversify their investment. This study looked at how the benefits from increase in farmers' rice yield contribute to farmers ability to acquire livelihood assets to enhance their standard of living. A sample size of 265 from a population of 880 farmers trained by Japan International Cooperation Agency on sustainable rainfed low-land rice production technology was used. The objective was to establish how proceeds from rice sale influenced the acquisition of livelihood assets by farmers to support their standard of living. Using spearman rho correlation, it was found that a strong positive correlation exists between increase rice output and livelihood assets acquisition. It is recommended that the technology should be disseminated nationwide specially in low-land rice farming areas so that all farmers in the country could benefit.     

Correlation and Volatility Dynamics in International Real Estate Securities Markets

We study international correlation and volatility dynamics of publicly traded real estate securities using monthly returns from 1984 and 2006. We also examine, for comparison, the correlations among the corresponding stock markets. A multivariate dynamic conditional correlation model captures the time-varying correlation within the full period. We confirm lower correlations between all real estate securities market returns than those between the stock market returns themselves. Some significant variations and structural changes in the correlation structure happened within the sample period. We detect a strong and positive connection between real estate securities market correlations and their conditional volatilities. We also find the international correlation structure of real estate securities and the broader stock market are linked to each other. Our results have economic motivations regarding the potential integration of international real estate securities markets and the possibility of including information on changing correlations and volatilities to design more optimal portfolios for international real estate securities.

Unification of Dual Foreign Exchange Markets

In this paper I investigate the impact of overnight floating of the official rate and easing foreign exchange restrictions on post-unification domestic inflation rate. After analysing the behaviour of an economy under dual foreign exchange markets, an official market with a crawling foreign exchange rate and a free illegal parallel market. The paper also shows that maintaining a unified free exchange rate depends on the degree of foreign exchange restrictions under dual foreign exchange system and on the level of the official reserve that prompts foreign exchange liberalisation policy. This revised version was published online in July 2006 with corrections to the Cover Date.     

Portfolio diversification: the influence of herding,status-quo bias,and the gambler’s fallacy

This experimental study examines the influence of herding [following the majority of fellow gamblers or the most successful gambler (guru)], status-quo bias, and the gambler’s fallacy on diversification behavior. We find that neither herding nor status-quo bias contributes significantly to non-optimal portfolio choices. The gambler’s fallacy, however, plays an important role in these decisions. Many subjects appear to find patterns in a history of random events and then use these “patterns” to infer the sequence of future events. The gambler’s fallacy is significantly responsible for the fact that the optimal structure of a portfolio is considered in only 37.7% of all choices made by an investor.
