this study has investigated the long-run and short-run effects of relative productivity on real exchange rate using annual time series data of iran and its major trade partners over the period 1980-2005. to analyze such effect which refers to the balassa-samuelson effect, this research uses auto-regressive distributed lags (ardl) method, to deal with dynamics of the relationship between product...

make or buy decision is one of the main areas of decision making for managers. transaction cost economics (tce), as an influential economic approach to the theory of the firm, tries to put forward a theoretical framework for this important decision. from tce perspective, the greater the asset specificity, the more the behavioral uncertainty and the more the transaction frequency, the more will ...

in this article, the effectiveness of eight different technical indexes including simple moving average, weighted moving average, exponential moving average, relative strength, commodity channel, stochastic, money flow and demand are examined by comparison between indexes returns with buy and hold returns. the results shows the return of buy and hold strategy is more than technical indexes in t...

A basic neoclassical model of production is often used to assess the contribution of investment to output growth. In the model, investment raises the capital stock and output growth increases in proportion to the growth in capital. It has been argued, however, that computers, as a “general purpose technology,” lead to process innovations and facilitate organizational coinvestments. Since there ...

Many forecasts are conditional in nature. For example, a number of central banks routinely report forecasts conditional on particular paths of policy instruments. Even though conditional forecasting is common, there has been little work on or with methods for evaluating conditional forecasts. This paper provides analytical, Monte Carlo, and empirical evidence on tests of predictive ability for ...

The authors examine the link between consumption and disaggregate wealth in Canada. They use a vector-error-correction model in which permanent and transitory shocks are identified using the restrictions implied by cointegration proposed by King, Plosser, Stock, and Watson (1991) and Gonzalo and Granger (1995). This procedure allows the authors to identify the reaction of consumption to both ty...

This paper evaluates the interacted effects of the fiscal and monetary policies on the nominal and real macro-variables of the Iranian economy. Our analysis is thus based on the optimal control theory by which the optimal path of the control variables including monetary and fiscal tools are determined over the period 1963-2006. We also use a macro-econometric model in form of a simultaneous equ...

abstract the aim of this study was to selecting the suitable model for forecast land, production and price of sugar beet in iran. for this purpose, models applied to forecast are arima, single and double exponential smoothing, harmonic, artificial neural network and arch for period 1993-2008. results of durbin-watson tests, land, production and price of sugar beet series were found non stochast...

The authors provide a detailed empirical analysis of Canadian city housing prices. They examine the long-run relationship between city house prices in Canada from 1981 to 2005 as well as idiosyncratic relations between city prices and city-specific variables. The results suggest that city house prices are only weakly correlated in the long run, and that there is a disconnect between house price...

Recently, a significant share of the empirical analysis on the impact of public capital on regional growth has used multivariate time-series frameworks based on vector auto regressive (VAR) models. Nevertheless, not as much attention has been dedicated to the analysis of the long-run determinants of regional growth processes using multi-region panel data and applying panel integration and co-in...
