this study estimates the residential property prices in tehran using hedonic price functions and spatial econometrics. the newly employed method is extending the analysis to the neighbourhood level (361 sectors) using the city's planning and gis tools. the results show that the spatial econometric model has higher identification than the simple econometric model. the distance between the c...

Currently, the Thailand government is promoting biofuel, especially producer of biodiesel. Starting from 2015, Ministry Energy has determined that palm oil remaining domestic consumption 14 million liters per day in 2036. Forecasting biodiesel prices are most important since price volatility affects renewable energy future. This paper presents with time series decomposition method. The source d...

This study investigates the impact of certain macroeconomic determinants on stock market returns in Gulf Cooperation Council (GCC). Those factors are: interest rates, oil prices, exchange and money supply. were empirically studied investigated to have an many countries. paper also attempts capture that those market, using a panel set data by implying several tests data, which include unit root ...

High dynamic-range imagers aim to block out or null light from a very bright primary star to make it possible to detect and measure far fainter companions; in real systems a small fraction of the primary light is scattered, diffracted, and unocculted. We introduce S4, a flexible data-driven model for the unocculted (and highly speckled) light in the P1640 spectroscopic coronograph. The model us...

We examine how asymmetric information and competition in the credit market affect voluntary information sharing between lenders. We study an experimental credit market in which information sharing can help lenders to distinguish good borrowers from bad ones, because borrowers may exogenously switch locations. Lenders, however, are also engaged in spatial competition, and lose market power by sh...

We develop a new concept of rural technology diffusion influenced by labor mobility and business relations. The technology gain effect of labor mobility increases technology diffusiveness, whereas the technology drain effect decreases it. The concept is applied to survey data from the Mekong region, a new geographic area in this context. In the econometric analysis that takes spatial correlatio...

We analyse the internal spatial wage and employment structures of the Czech Republic, Hungary, Poland, Slovakia and Slovenia, using regional data for 1996–2000. A new economic geography model predicts wage gradients and specialization patterns that are smoothly related to the regions’ relative market access. As an alternative, we formulate a ‘Comecon hypothesis’, according to which wages and se...

Spatial baseline determination is a key technology for interferometric synthetic aperture radar InSAR missions. Based on the intersatellite baseline measurement using dual-frequency GPS, errors induced by InSAR spatial baseline measurement are studied in detail. The classifications and characters of errors are analyzed, and models for errors are set up. The simulations of single factor and tota...

We consider testing the null hypothesis of no spatial correlation against the alternative of pure first order spatial autoregression. A test statistic based on the least squares estimate has good first-order asymptotic properties, but these may not be relevant in small or moderate-sized samples, especially as (depending on properties of the spatial weight matrix) the usual parametric rate of co...

The smooth threshold autoregressive (STAR) model is by far the most successful model in explaining the well-known two PPP puzzles. The nonlinearity in STAR captures the nature of vast transaction costs in trade, sunk costs in (foreign) investment, and hetergeneity in agents. In this paper, we use a variant of STAR, the Exponential STAR (ESTAR), to study the exchange rate dynamics in China durin...
