Financial time series including high frequency structures like jumps, spikes and stochastic volatility are usually modeled in an ad-hoc manner by stochastic differential equations together with Levy processes. Estimating the parameters and determining the jump size distributions do not have a precise and universally accepted method. Under these circumstances, complexities and confusions usually arise. This book, approaches to this issue from a very different angle through introducing an autocorrelation one process together with finite number of Fourier series terms. Introduction of Fourier series to estimate the dynamics of the process is not done in an ad-hoc manner or as done before in dealing with seasonality. Here the moving average is transformed to a “moving and fluctuating” average by the help of Fourier series. Instead of adding jump structures to the model which makes the parameter estimation quite cumbersome, our model in discrete time can easily be transformed to a well-known mean reverting continuous time process. Moreover, our alternative model turned out to be a quite powerful and accurate forecasting technique.

Son dönemlerde Türkiye’de konut ve kentleşme kavramları, kentsel dönüşüm uygulamalarının da etkisiyle dikkat çeken konular arasında yer almaktadır. Oluşturulan plan ve programların temelinde yer alan ve öncelikli konulardan biri olan konut kavramı, bu kitabın ana konusunu oluşturmaktadır. Mikroekonomik açıdan konut piyasasının gelişimi ve makro açıdan ise konut piyasasının büyüme ile olan ilişkisi çalışmada yer alan konular arasındadır. Bununla birlikte çalışmada tanımlayıcı istatistiklere yer verilerek konut piyasası incelenmekte ve konut talebini belirleyen değişkenler ampirik bir modelleme ile tahmin edilmektedir.

The Belt and Road Initiative is the most ambitious project in the 21^st century. Its main goals are infrastructure development, financial integration, people to people connectivity. Developing countries which desperately need infrastructure upgrade welcomed Chinese investments, finding an opportunity to be connected to global economy. Although economic and political consequences are discussed in the literature, the spatial consequences of the Belt and Road Initiative are neglected. The Belt and Road Initiative lays out six main economic corridors, reconfiguring the space across the continents. Eurasia, where three of six economic corridors pass through, is mostly affected by this spatial process. The countries in Eurasia are linked with corridors on which dry ports, special economic zones, and free trade areas are set up. This signifies new spatial characteristics in Eurasia.
