Incorporating Seasonality into an Agroeconomic Model of Ethiopia
Incorporating Seasonality Agroeconomic Model Ethiopia
2024/4/1
Ethiopia’s agriculture-based economy generates highly seasonal outputs, with most production occurring during the long-rains Meher season and a lesser amount during the short-rains Belg season. Despit...

New software tool model economic environmental impacts California drought
2020/7/10
Drought may mean restrictions for watering lawns, crop losses for farmers and an increased risk of wildfires. But it can also hit power companies in the wallet.In communities that rely on water for po...
METHOD OF GRASSLAND INFORMATION EXTRACTION BASED ON MULTI-LEVEL SEGMENTATION AND CART MODEL
Grassland Extraction Multi-level Segmentation Feature Selection CART Model Xilinhaote City
2018/5/15
It is difficult to extract grassland accurately by traditional classification methods, such as supervised method based on pixels or objects. This paper proposed a new method combing the multi-level se...
The workshop aims to describe the complex interplay of IoT technology invention and the business model innovation associated with the utilization. The interdisciplinary studies of interest include but...

Multi-criteria evaluation model to face phytosanitary emergencies:The case of citrus fruits farming in Italy
economic planning Citrus Tristeza Virus social choice NAIADE method social multi-criteria evaluation
2016/6/3
In the last decade, citrus fruits farming, at the international level, revealed an upward trend changing the traditional scenarios of the offer, with the exchange of products coming from all areas of ...
Term Structure Modelling by Using Nelson-Siegel Model
Nelson-Siegel model Nonlinear least squares Yield curve estimation
2016/1/27
Zero coupon rates are not observable in the market for a range of maturities. Therefore, an estimation methodology is required to derive the zero coupon yield curves from observable data. If we deal w...
Impact of price realization on India’s tea export: Evidence from Quantile Autoregressive Distributed Lag Model
export price realization, Quantile Autoregressive Distributed Lag model India
2015/10/9
Th e quantile autoregressive distributed lag model of Galvao et al. (2013) was employed to assess the impact of
price realization on India’s tea export. Th e results of the QADL varied signifi...
A Model of Dynamic Limit Pricing with an Application to the Airline Industry
entry deterrence limit pricing asymmetric information airlines
2015/9/24
Theoretical models of strategic investment often assume that information is asymmetric, creating incentives forincumbent firms to signal information to deter entry or encourage exit. However, the simp...
A Generalized Spatial Two-Stage Least Squares Procedure for Estimating a Spatial Autoregressive Model with Autoregressive Disturbances
Spatial autoregressive model two-stage least squares generalized moments estimation
2015/9/24
Cross-sectional spatial models frequently contain a spatial lag of the dependent variable as a regressor or a disturbance term that is spatially autoregressive. In this article we describe a computati...
INSTRUMENTAL VARIABLE ESTIMATION OF A SPATIAL AUTOREGRESSIVE MODEL WITH AUTOREGRESSIVE DISTURBANCES:LARGE AND SMALL SAMPLE RESULTS
INSTRUMENTAL VARIABLE ESTIMATION SPATIAL AUTOREGRESSIVE MODEL AUTOREGRESSIVE DISTURBANCES LARGE AND SMALL SAMPLE
2015/9/24
The purpose of this paper is two-fold. First, on a theoretical level we introduce a series-type instrumental variable (IV) estimator of the parameters of a spatial first order autoregressive model wit...
A SPATIAL CLIFF-ORD-TYPE MODEL WITH HETEROSKEDASTIC INNOVATIONS: SMALL AND LARGE SAMPLE RESULTS
SPATIAL CLIFF-ORD-TYPE MODEL HETEROSKEDASTIC INNOVATIONS SMALL AND LARGE SAMPLE RESULTS
2015/9/24
In this paper, we specify a linear Cliff-and-Ord-type spatial model. The model allows for spatial lags in the dependent variable, the exogenous variables, and disturbances. The innovations in the dist...
2SLS and OLS in a spatial autoregressive model with equal spatial weights
Spatial autoregressive models Row normalized and equal spatial weights Ordinary least squares Two stage least squares Panel data
2015/9/24
The paper considers a Cliff–Ord type spatial model with a spatially lagged dependentvariable and a row normalized weighting matrix with equal weights. We show that the 2SLSand OLS estimators are incon...
BAYESIAN AND DOMINANT STRATEGY IMPLEMENTATION IN THE INDEPENDENT PRIVATE VALUES MODEL
Independent private values incentive compatibility Bayesian implementations dominant-strategy implementation adverse selection bilateral trade mechanism design
2015/9/23
We prove—in the standard independent private-values model—that the outcome, in terms of expected probabilities of trade and expected transfers, of any Bayesian mechanism, can also be obtained with a d...
