Abstract

Attainment of standards in a country’s real estate market to meet international investors’ expectations contributes significantly to the real estate sector. However, in developing economies characterized by an environment of uncertainty where stability cannot be achieved, direct investments in real estate can bring returns to foreign investors. This is because economic uncertainty in developing countries raises the exchange rate. An increase in the exchange rate keeps real estate prices in developing countries relatively low. Foreign investors then take advantage of the low prices to invest in real estate in that country. The study aims to research whether the uncertainty in developing countries increases the foreign direct real estate investments. The study examines the relationship between the uncertainties in selected developing economies in Europe and the real estate investments by foreigners in the period 2008–2018. Gengenbach, Urbain, and Westerlund Panel Cointegration test and PDOLS coefficient estimation methods were used in the study. According to the analysis results, a 1% increase in the uncertainty index in the economies examined increases foreign direct investments by 5.731%. Since this study is one of the most detailed studies measuring foreign direct real estate investments under uncertainty conditions in the economy, it contributes to the literature. To sustainably increase foreigners’ direct real estate investments in developing countries, economic and political stability should be prioritized. Facilitating the bureaucratic process, providing tax reductions, making real estate suitable for demand, following the appropriate price policy, and making various environmental regulations will also increase foreigners’ direct real estate investments. Doi: 10.28991/esj-2021-01293 Full Text: PDF

Abstract

There are many types of skewed distribution, one of which is the lognormal distribution that is positively skewed and may contain true zero values. The coefficient of quartile variation is a statistical tool used to measure the dispersion of skewed and kurtosis data. The purpose of this study is to establish confidence and credible intervals for the coefficient of quartile variation of a zero-inflated lognormal distribution. The proposed approaches are based on the concepts of the fiducial generalized confidence interval, and the Bayesian method. Coverage probabilities and expected lengths were used to evaluate the performance of the proposed approaches via Monte Carlo simulation. The results of the simulation studies show that the fiducial generalized confidence interval and the Bayesian based on uniform and normal inverse Chi-squared priors were appropriate in terms of the coverage probability and expected length, while the Bayesian approach based on Jeffreys' rule prior can be used as alternatives. In addition, real data based on the red cod density from a trawl survey in New Zealand is used to illustrate the performances of the proposed approaches. Doi: 10.28991/esj-2021-01289 Full Text: PDF
